Origin of Permian gabbroic intrusions in the southern margin of the Altai Orogenic belt: A possible link to the Permian Tarim mantle plume?  

NASA Astrophysics Data System (ADS)

Zircon U-Pb dating and Hf isotopic compositions, whole-rock and mineral geochemistry, as well as field and petrographic observations, are reported for the Permian gabbroic intrusions in the southern margin of the Altai orogenic belt. Similar zircon ages (~ 280 Ma) of these intrusions to that of the Permian Tarim mantle plume suggest a possible link to the Tarim plume. Olivine grains from the intrusions have Fo contents ranging from 69 to 81 and NiO from 0.05 to 0.21 wt.%, indicating the crystallization from evolved mafic magmas. Clinopyroxene grains from the intrusions have 0.3 to 1.5 wt.% TiO2 and display a rift- to arc-like affinity. The intrusions are tholeiitic and have slightly LREE-depleted to LREE-enriched chondrite-normalized rare earth element (REE) patterns. Zircons from the intrusions have ?Hf(t) values higher than + 8.0, whereas the whole-rock ?Nd(t) values range from + 2.7 to + 7.0. Rocks from the intrusions have Nb/La of 0.2 to 0.8, consistent with the derivation from a depleted sub-lithospheric mantle with variable degrees of crustal contamination. The presence of primary hornblende and/or biotite in the rocks indicates metasomatism by slab-derived fluids/melts in the mantle source. We propose that upwelling of asthenospheric mantle in the Permian Tarim mantle plume along the Irtish suture zone, resulted in partial melting of the sub-continental lithospheric mantle. Based on a comparison between the Ni-Cu sulfide-bearing Kalatongke complex and un-mineralized intrusions, we suggest that Ni-Cu sulfide mineralized intrusions in the Altai orogenic belt are characterized by the enrichments of LREEs and LILEs and by the presence of primary water-bearing minerals.

Accretionary history of the Altai-Mongolian terrane: perspectives from granitic zircon U-Pb and Hf-isotope data  

NASA Astrophysics Data System (ADS)

The Central Asian Orogenic Belt (CAOB) consists of many tectonic terranes with distinct origin and complicated evolutionary history. Understanding of individual block is crucial to reconstruct the geodynamic history of the gigantic accetionary collage. This study presents zircon U-Pb ages and Hf isotopes for the granitoid rocks in the Russian Altai mountain range (including Gorny Altai, Altai-Mongolian terrane and CTUS suture zone between them), in order to clarify the timing of granitic magmatism, source nature, continental crustal growth and tectonic evolution. Our dating results suggest that granitic magmatism of the Russian Altai mountain range occurred in three major episodes including 445~429 Ma, 410~360 Ma and ~241 Ma. Most of the zircons within the Paleozoic granitoids present comparable positive ?Hf(t) values and Neoproterozoic crustal model ages, which favor the interpretation that the juvenile crustal materials produced in the early stage of CAOB were probably dominant sources for the Paleozoic magmatism in the region. The inference is also supported by widespread occurrence of short-lived juvenile materials including ophiolites, seamount relics and arc assemblages in the north CAOB. Consequently, the Paleozoic massive granitic rocks maybe not represent continental crustal growth at the time when they were emplaced, but rather record reworking of relatively juvenile Proterozoic crustal rocks although mantle-derived mafic magma was possibly involved to sever as heat engine during granitic magma generation. The Early Triassic granitic intrusion may be product in an intra-plate environment, as the case of same type rocks in the adjacent areas. The positive ?Hf(t) values (1.81~7.47) and corresponding Hf model ages (0.80~1.16 Ga) together with evidence of petrology are consistent with the interpretation that the parental magma of the Triassic granitic intrusion was produced from enriched mantle-derived sources under an usually high temperature condition which is likely due to basaltic magma that underplated the lower crust. Our data combined with evidence of the regional geology enable us to conclude that the Gorny Altai and Altai-Mongolian terranes possibly have similar tectonic natures, but represent two separate accretionary systems before Devonian collision. The accretion and amalgamation processes resulted in the Paleozoic granitoid magmatism and caused the two terranes to merge as a composite tectonic domain at the Siberian continental margin.

[Haplotype diversity in mtDNA and Y-chromosome in populations of Altai-Sayan region].  

PubMed

Polymorphism of mtDNA was examined in five ethnic populations that belong to the Turkic language group and inhabit the territory of the Altai-Sayan upland (N = 1007). Most of the haplogroups identified in the examined populations belonged to East Eurasian lineages. In all five populations, only three haplogroups, C, D, and F, were prevailing. The frequencies of the other six haplogroups (A, B, G, M, Y, and Z) varied in the range from 1.1 to 6.5%. Among West Eurasian haplogrous, the most common were haplogroups H, J, T, and U. An analysis of Y-chromosome haplogroups in 407 individuals showed that only two haplogroups, N* and R1a1, were present in all five populations examined. Moreover, in different ethnic groups, the highest frequencies were observed for C-M130, N-P43, and N-Tat haplogroups. The differences in the distribution patterns of ancient West Eurasian and East Eurasian haplotypes from Gorny Altai in the present-day populations from the northern part of Eurasia revealed can be explained in terms of the multistage expansion of humans across these territories. The ubiquity of haplotypes from haplogroup H and cluster U across the wide territory from the Yenisei River basin to the Atlantic Ocean can indicate directional human expansion, which most likely occurred out of Central Asia as early as in the Paleolithic era, and took place in several waves with the glacier retreat.

A Few Issues on the Peat Research in the Altai Mountains  

NASA Astrophysics Data System (ADS)

At the present time we carry out complex research of marsh ecosystems in various areas of Gorny Altai to reveal the perspective deposits of peat in the Altai Mountains with the purpose of its use in the medical and recreational spheres. The peat deposits of the Northeastern Altai, Central Altai, and Southeastern Altai are surveyed; the selective chemical analysis of peat and marsh waters is carried out. The group structure of organic substance of various samples of peat is investigated by the method of Institutes of Peat. The toxic metals of Cd, Pb, Hg, Cu, Zn, and As were defined by the method of stripping voltammetry. The region of the Altai Mountains is characterized by the contrastive distribution of some heavy metals and arsenic in a soil cover. This is caused by a variety of petrography and granulometry of soil forming material, and also by a landscape and geochemical situation in the system of vertical zoning. The sources of natural accumulation of heavy metals in the ground might be the deposits of polymetals. In this connection the content of the specified toxic elements in the peat under research has been identified. The peat of the Turochak deposit is characterized by a significant ash content - up to 41,9%; the increased ash content is typical of the Kutyush deposit: from 6,1% up to 19, %. The peat of the Northeastern Altai is referred to non-bitumunous: the content of bitumen makes up less than 5%. In comparison with the European peat the peat under study of the transitive and lowland type is characterized by the significant content of easy hydrolysable substances in the amount of 24,8-41,1%. The amount of the non-hydrolysable rest makes up around 4,3 - 7,4 %. The total content of fulvic acids is less than the content of humic acids by 2,9 - 5,8 times. The high content of humic acids which can reach up to 58 % is characteristic of certain deposits. Humic acids extracted from the peat are characterized, as a rule, by similar IR-spectra. The distinctions are shown in an unequal intensity of characteristic absorption bands, in their spreading and some shifts. It is revealed that humic acids of peat with the increase in a degree of decomposition are exposed to transformation; therefore the increase in their structure of functional groups is observed. As a result of the research which was carried out the following elements among heavy metals in the lowland peat of the Altai Mountains are revealed: Cd (2,7 - 30)> Hg (0,67)> Zn (0,22) ~Pb (0,21)> Cu (0,13)> As (0,03). The degree of mobility of chemical elements in the peat varies within the limits of 1,3 - 36%. According to the degree of their mobility these elements form the following line: Zn (36 %)> Pb (18,1 %)> Cd (9,6 %)> Cu (1,3 %). The content and the character of distribution of the heavy metals under study and arsenic in the peat of the Altai Mountains have their unique features in comparison with the same valley analogues. The mountain peat of the Central Altai contains much less Hg than the West Siberian one: 0,078 mg/g and 0,69 mg/g accordingly. Cd represents itself as the concentrator in the lowland peat of the Northeastern and Central Altai, its content is actually the same and makes up approximately 0,3 mg/kg. The lowland Altai and West Siberian peat has the same amount of Pb: 4-5 mg/kg; they have smaller amounts of Zn and Cu in comparison with the European and West Siberian peat. The revealed features of distribution of some toxic metals are the display of specificity of peat genesis in the conditions of a mountain relief. The complex of the data received by us allows to consider the peat of the Altai Mountains as a non-polluting raw source concerning the amount of some natural toxic substances. The possible perspective directions of practical application of the mountain peat can be medicine, veterinary science, and agriculture.

Tectonic Setting and Structural Evolution of the Late Cenozoic Gobi Altai Orogen, Mongolia  

NASA Astrophysics Data System (ADS)

The Gobi Altai is an intraplate, intracontinental transpressional orogen in southern Mongolia that formed in the Late Cenozoic as a distant response to the Indo-Eurasia collision. The modern range formed within crust constructed by successive terrane accretion and ocean suturing events and widespread granite plutonism throughout the Paleozoic. Modern reactivation of the Gobi Altai crust and the kinematics of Quaternary faults are fundamentally controlled by Paleozoic basement structural trends, the location of rigid Precambrian blocks, orientation of SHmax and possible thermal weakening of the lower crust due to an extensive history of Mesozoic-Cenozoic basaltic volcanism in the region, and the presence of thermally elevated asthenosphere under the Hangay Dome to the north. Modern mountain building processes in the Gobi Altai typically involve reactivation of NW-striking basement structures in thrust mode and development of linking E-W left-lateral strike-slip faults which crosscut basement structures within an overall left-lateral transpressional regime. Restraining bends, other transpressional ridges and thrusted basement blocks are the main range type, but are discontinuously distributed and separated by internally drained basins filling with modern alluvial deposits. Unlike a contractional thrust belt, there is no orogenic foreland or hinterland, and thrusts are both NE and SW directed with no evidence for a basal decollement. Normal faults related to widespread Cretaceous rifting in the region appear to be unfavourably oriented for Late Cenozoic reactivation despite widespread topographic inversion of Cretaceous basin sequences. The discovery of major Cretaceous normal fault systems in the Gobi Altai has important implications for workers investigating the region's neotectonic development, because the pre-existing rift basin architecture may have influenced the modern orogenic architecture and network of seismically active faults. Although the Gobi Altai has structural and basinal elements similar to continental transform systems undergoing transpressional deformation, such as the San Andreas system, it differs in several important aspects. The Gobi Altai is a reactivated mechanically weak belt between more rigid basement blocks in a continental interior. The Gobi Altai does not transfer plate motions, but terminally accommodates intraplate strain by oblique deformation. The Gobi Altai is a diffuse belt of deformation, but no singular strike-slip fault is dominant as is the case with the San Andreas Fault or Dead Sea Transform. Because the Gobi Altai is an actively developing youthful mountain range in an arid region with low erosion rates, it provides an excellent opportunity to study the way a continental interior reactivates due to a distant continental collision. Preserved peneplain surfaces, fresh alluvial fans, and sharply defined fault scarps and active mountain fronts express a very strong tectonic signal, without the obscuring effects of a humid/high erosion rate climate signal. Finally, the Gobi Altai is a useful analog for how other more advanced intracontinental transpressional orogens such as the eastern Tien Shan and Altai developed during earlier stages of their evolution.

[Polymorphism of the Y-chromosome diallelic loci in the ethnic populations of the Altai-Sayan region].  

PubMed

Using the data on five biallellic Y-chromosome loci (DYS199, 92R7, SRY1532, RBF5 and DYS287) polymorphism, genetic structures of the five Turkic-speaking ethnic groups of the Altai-Sayan highland (Tuvinians, Sojots, Shorians, Khakassians, and Southern Altaians (Altai-Kizhi), were described. The gene pools of the populations examined were characterized by the presence of pronounced paleo-Caucasoid component (92R7-T-lineages). The frequency of this component increased westward, reaching more than 70% in Shorians and Southern Altaians. Haplotype TAT-C (RBF5 locus) was observed in all populations, except Shorians, with the frequencies varying from 5.4% in Altai-Kizhi to 18.8% in Khakassians. The Alu-insertion in the DYS287 locus was revealed only in the Altaian sample with the frequency of 3.3%. It was established that the Altai-Sayan populations studied split into two statistically significantly different groups. One of the groups was represented by Tuvinians, Sojots, and Khakassians, while another one was comprised of Shorians and Altaians. PMID:11963568

Oceanic Basalts of the Paleo-Asian Ocean: Geochemistry and Structural Setting in Folded Zones of Altai and East Kazakhstan (Central Asia)  

NASA Astrophysics Data System (ADS)

Four periods of basaltic volcanism of the Paleo-Asian Ocean have been studied: 1) Vendian-Early Cambrian (Kurai zone); 2) Early-Middle Cambrian (Katun zone); 3) Late Cambrian-Early Ordovician (Zasurin Formation) and 4) Late Devonian-Early Carboniferous (Chara belt) ages. The studied entities are oceanic basalts incorporated in four Caledonian accretion-collision zones.The Early Cambrian collision of the Siberian continent and Gondwana-derived terranes formed the Kurai and Katun accretionary zones in Gorny Altai. The Late Cambrian-Early Ordovician collision of the Siberian continent and Gondwana-derived terranes formed shear zones comprising oceanic sediments and basalts (Zasurin Formation). The Late Devonian-Early Carboniferous collision of the Siberian and Kazakhstan continents formed the Chara shear belt including basaltic terranes (Buslov et al., 2001). Geochemical features of tholeiites, subalkaline and alkaline basalts incorporated in accretionary terranes illustrate the history of oceanic volcanism with OIB, OPB and MORB affinities. According to REE there are LREE-enriched, transitional and MORB/OPB-like samples. LREE vary and are considerably enriched (LaN (ppm) 25-65 for Kurai, 35-55 for Katun, 100-160 for Zasurin, and 35-105 for Chara OIB) relative to chondrites. HREE have much smaller ranges: 6 to 13 times that of chondrites for Kurai and Katun and 10 to 20 times for Zasurin and Chara. There is also a positive correlation between La/Yb and SiO2. In the multi-element diagrams Kurai samples display Sr enrichment relative to K, whereas Zasurin and Chara samples show negative Sr peaks. Except for the Katun wedge, most display moderate to strong Nb-Ta depletion suggesting fractionation of ilmenite and magnetite at the base of the crust or a previous melting episode in the source. For all groups of basalts, transitions between end members of basalts: from N-MORB, through E-MORB and T-MORB (OPB?) to OIB were found. Zr/Y and Sm/Nb ratios show two distinct linear trends suggesting two independent magma sources regardless of ages: near-constant Zr/Y=2-3 and Sm/Nb=1-1.5 probably represent MORB or OPB while Zr/Y=6 and Sm/Nb=5-6 represent OIB-type rocks. The oceanic metabasalts from those four areas display many common geochemical features. On one hand, they could have been melted at different degrees of partial melting and at different depths. On the other hand they could have melted from one mantle source, but then differently influenced and/or contaminated by the upper mantle, for example, a weakly depleted oceanic mantle could interact with upwelling plume melts. Thus, the fragments of oceanic crust from Gorny Altai, North-West Altai and East Kazakhstan comprise not only ophiolitic rock units, but also oceanic plateau and oceanic island units as important markers in reconstruction of the structure of foldbelts. It is concluded that intra-plate volcanism was active in the Vendian to Early Carboniferous period of the evolution of the Paleo-Asian Ocean. The fragments of weakly to strongly differentiated oceanic basalts have been preserved in accretion-collision zones and their geochemical data indicate that the Altai and East Kazakhstan metabasalts could have been formed at mid-oceanic ridges, oceanic islands or oceanic plateaux of the Paleo-Asian Ocean in Vendian to Early Carboniferous times. This study was supported by RFBR grants no. 01-05-65228, 02-05-64627 and 03-05-64668.

Reflection of climatic changes in Altai phenology  

NASA Astrophysics Data System (ADS)

The last decades of the past century showed noticeable climate changes in many parts of the Earth (IPCC, 2007). Numerous models suggest that the climate changes will continue, showing a variable intensity especially in mountain regions. Altai Mountains, located at the boundary of taiga, desert, and semiarid regions of Central Asia, are exposed to intensive climatic and environmental changes. Analysis of changes in phenological parameters is the simplest process for track changes in the ecology of species in response to climate change. We present climatic characteristic and statistical analysis changes of thermal and precipitation regimes in Altai Mountains (Russian and Mongolian Altai), and the response of phenological parameters to these changes. The close correlation between temperature series of the Russian and northern part of Mongolian Altai is determined. At the same time, a correlation between precipitation data is observed only for the cold (November - March) seasons. It was found that the rate of temperature increase for the period under consideration (1940-2012) ranged from 0.15 to 0.55 ° C/10 years, and the most significant increase was registered during the cold seasons. An increase of annual means of precipitation is in the range from 2.32 to 6.37 mm / 10 years. The maximal increase (29 mm / 10 years) was observed in the data from the Kara-Tyureck station, whose location is the highest one of the considered stations (2600 m). During the maximal warming (1980-1999), a 2-4.5 times increase of annual average temperature was observed as compared to the period of 1940 - 1979. The amount of precipitation is increased for Ust'-Koksa (5 times) and Ulgiy (2 times) stations, but it is 3 times lower for Kosh-Agach and Kara-Tyureck stations. The results of the correlation analysis of temperature and precipitation data for the analyzed Russian and Mongolian Altai stations were confirmed and detailed by the wavelet and wavelet coherence / phase analysis. The temperature series variations obtained with the wavelet analysis correspond to the periods of North Atlantic Oscillation and solar activity variation, and precipitation are in good agreement with changes in Pacific Decadal Oscillation. The analyzed climatic change influenced on the beginning of pollination of different plant species in Altai region. If average (for 27 years) of the beginning of pollination of Artemisia gmelinii (a typical representative of Central Asian steppe vegetation) was counted at 24 of August, a mass pollination of this species was at 5th of September. So deviation reached 14 days. Under condition of more cool summer the pollination in most cases (80 %) started later. Additionally we counted average temperature of beginning of pollination of this species which was + 21.5 C0, and sums of action temperatures (+5 C0) = 1675, (+10 C0) = 1491.

The Altai Mountains environmental disaster (Eastern Kazakhstan)  

NASA Astrophysics Data System (ADS)

The space centre "Baikoniyr" (Kazakhstan) has had substantial affects on the environment. During the past several decades as a result of the launching of carrier rockets, such as "Proton" that use as fuel the asymmetrical dimethylhydrazine (ASDH), more well-known as "heptyl", the unique mountain landscapes in Eastern Kazakhstan have been subjected to pollution. In 2004, RSE "Kazakh research Institute of Ecology and Climate" carried out the complex geochemical and radiation researches in East Kazakhstan that is an impact area of second stages of carrier rockets. Such detailed examinations of this area were conducted for the first time because the Eastern Kazakhstan Mountains are difficult for human access. The landscape-geochemical research over the natural landscapes covered the ridge, low, and middle mountains with fir forests. The research results have shown the presence of heptyl in the samples of the soil, plants, and rivers’ bottom sediments. The findings of the influence of space activity on environment of the Kazakhstan part of the Altai Mountains confirm and complement the Russian scientific research results over the territory of the neighbouring Altai Krai. Though the heptyl pollution in the investigated region is of a local nature and highly spatially inhomogeneous, nevertheless, this anthropogenic effect intensifying from year to year increases the load on the natural ecosystems. In particular, it strengthens the desertification process of mountain regions of East Kazakhstan.

First molecular screening of deafness in the Altai Republic population  

PubMed Central

Background We studied the molecular basis of NSHL in Republic of Altai (South Siberia, Russia). The Altaians are the indigenous Asian population of the Altai Mountain region considered as a melting-pot and a dispersion center for world-wide human expansions in the past. Methods A total of 76 patients of Altaian, Russian or mixed ethnicity and 130 Altaian controls were analyzed by PCR-DHPLC and sequencing in the GJB2 gene. The GJB6 deletion and the common non-syndromic deafness-causing mitochondrial mutations were also tested when appropriate. Results 8.3% of the Altaian chromosomes were carrying GJB2 mutations versus 46.9% of the Russian chromosomes. The 235delC mutation was predominant among Altaians, whereas the 35delG mutation was most prevalent among Russian patients. Conclusion We found an Asian-specific GJB2 diversity among Altaians, and different GJB2 contribution for deafness in the Altaian and Russian patients. The high carrier frequency of 235delC in Altaians (4.6%) is probably defined by gene drift/founder effect in a particular group. The question whether the Altai region could be one of founder sources for the 235delC mutation widespread in Asia is open. PMID:15790391

Biological proxies recorded in a Belukha ice core, Russian Altai  

NASA Astrophysics Data System (ADS)

Different biological proxies such as pollen, cysts, and diatoms were identified and quantified in the upper part of a Belukha ice core from the Russian Altai. The ice core from the Belukha glacier collected in 2001 (4062 m a.s.l., 49°48' N, 86°34' E) was analyzed with annual resolution in the period 1964-2000. Daily data of the frequency of synoptic patterns observed in the Northern Hemisphere along with daily data of precipitation have been used to identify the predominant atmospheric circulations (elementary circulating mechanisms, or ECMs) generating the entry of biological proxies on the glacier surface. It was shown that the high-resolution records of diatoms, cysts, spores, and plant pollen in the Belukha ice core are the biological proxies for the changes in the structure of precipitation in the Altai region since these records can reflect changes in the contribution of different atmospheric circulation to annual or seasonal precipitation. The joint consideration of the transport ability of the biological species and the data of precipitation allowed us to determine the main modern sources of biological proxies deposited at the Belukha glacier. The main sources of diatoms in the Belukha ice core are water bodies of the Aral, Caspian, and northern Kazakhstan basins; coniferous tree pollen originated from the taiga forest of the boreal zone of western Siberia; pollen of deciduous trees and herbs from steppe and forest-steppe vegetation in the northern Altai and eastern Kazakhstan; and cysts and spores of plants were transported from local water bodies and forests. The identified source regions of the biological species are supported by back trajectory analyses and are in good agreement with emission source regions of the trace elements in the ice core.

Biological proxies recorded in a Belukha ice core, Russian Altai  

NASA Astrophysics Data System (ADS)

Different biological proxies such as pollen, cysts, and diatoms were identified and quantified in the upper part of a Belukha ice core from the Russian Altai. The ice core from the Belukha glacier collected in 2001 (4062 m a.s.l., 49°48' N, 86° 34' E) was analyzed with annual resolution in the period 1964-2000. We used daily data of the frequency of synoptic patterns observed in the Northern Hemisphere along with daily data of precipitation to identify the main modern sources of biological proxies deposited at the Belukha glacier. Our analyses revealed that main sources of diatoms in the Belukha ice core are water bodies of the Aral, Caspian, and North Kazakhstan basins. Coniferous trees pollen originated from the taiga forest of the boreal zone of West Siberia and pollen of hardwoods and herbs from steppe and forest steppe vegetation in the Northern Altai and East Kazakhstan. Cysts of algae and spores of inferior plants were transported from local water bodies and forests. The identified source regions of the biological species are supported by back trajectory analyses and are in good agreement with emission source regions of the trace species in the ice core.

Provenance of Early Paleozoic metasediments in the central Chinese Altai: Implications for tectonic affinity of the Altai-Mongolia terrane in the Central Asian Orogenic Belt  

NASA Astrophysics Data System (ADS)

The Chinese Altai is one of the most typical segments of the Altai-Mongolia terrane, of which the tectonic evolution and affinity are hotly disputed and still not well constrained. Early Paleozoic metasedimentary rocks are extensive in the Altai-Mongolia terrane and their provenance is a key to unravelling the tectonic history of this terrane. Metasediments from Kulumuti Group were collected from the central Chinese Altai for geochemical study. They have low Chemical Index of Alteration (CIA = 52-54) and high Index of Compositional Variability (ICV = 0.81-1.19) values, different from the mature post-Archean Australian average shale (PAAS), indicating relatively weak chemical weathering and a source compositionally dominated by immature material that lacks alumina-rich minerals. These rocks are moderately enriched in light rare earth element (LREE) and show relatively flat heavy rare earth element (HREE) patterns (LaN/YbN = 2.36-9.80, GdN/YbN = 1.31-2.45). Compared with PAAS, they mostly have lower large ion lithophile element concentrations (e.g. Rb, Sr, Ba, Th, U and Pb) and similar contents of high field strength elements (e.g. Zr, Hf and Y), but with lower Nb and Ta. The metasediments have high Rb concentrations (> 50 ppm), relatively high K2O (> 1.1 wt.%) and low REE contents with negative Eu/Eu* anomalies, indicating that these rocks were derived from an acid-intermediate igneous source. The rocks have slightly enriched Nd isotopic compositions with calculated initial ?Nd(t) values mostly ranging from - 4.3 to - 0.2 and TDM2 model ages between 1.22 and 1.56 Ga. Detrital zircons from two samples of the Kulumuti metasediments have similar age spectra, dominated by Early Paleozoic to latest Neoproterozoic zircons (465-576 Ma) with a few older grains formed between 766-972 Ma and 1321-2572 Ma, remarkably consistent with those from the low-grade metamorphic Habahe Group in the western Chinese Altai. In combination with previous published data, the detrital zircons from Early Paleozoic metasediments in the Chinese Altai dominantly formed between 430-580 and 750-950 Ma, with only a minor population of Meso- to Paleoproterozoic grains. When compared with adjacent terranes, the age spectrum of the Chinese Altai is most similar to that of the Tarim Craton. This craton provided Precambrian materials for the Early Paleozoic metasedimentary rocks now exposed in the Chinese Altai, and therefore suggests that the whole Altai-Mongolia terrane has a close tectonic affinity to the Tarim Craton.

Arsenic in the soil-natural water-plant system of the Altai region  

NASA Astrophysics Data System (ADS)

The high natural content of total arsenic in the soil cover of the Altai region has been revealed. Natural waters and plants are distinguished by low arsenic concentrations. The intensity of the biogenic and water migration of arsenic does not depend on its total content in the soil. The accumulative distribution of arsenic in the mountainous forest soils of Altai is mainly due to biogenic processes, while in the steppe soils, it is specified by the evaporative concentration. Favorable conditions for arsenic migration are observed in the southeastern Altai during the periods of seasonal moistening. The arsenic content in the soils and plants of technogenic landscapes in the Altai region considerably exceeds the provisional permissible concentrations and the background concentrations of this element.

Hybrid dysgenesis determinants in a natural Drosophila population from Altai  

SciTech Connect

Localization of mobile elements P and hobo in the genomes of isofemale Drosophila lines obtained from a natural population from Biisk (Altai) was analyzed by in situ hybridization. The average copy number per genome was 27.1 for P and 22.0 for hobo. The highest number of P and hobo copies was recorded in the 3R and 21 chromosomes, respectively. The X chromosome contained the lowest number of hobo copies. For P, this relationship was not shown. Both transposons had preferential localization sites, or {open_quotes}hot spots,{close_quotes} which partly coincided with intercalary heterochromatin regions. Correlation analysis of P and hobo copy number showed independent distribution of these hybrid dysgenesis determinants. The 1A site, which is thought to be associated with the P cytotype expression, was not labelled in any line. 40 refs., 1 fig., 5 tabs.

Tracing the origin of the east-west population admixture in the Altai region (Central Asia).  

PubMed

A recent discovery of Iron Age burials (Pazyryk culture) in the Altai Mountains of Mongolia may shed light on the mode and tempo of the generation of the current genetic east-west population admixture in Central Asia. Studies on ancient mitochondrial DNA of this region suggest that the Altai Mountains played the role of a geographical barrier between West and East Eurasian lineages until the beginning of the Iron Age. After the 7th century BC, coinciding with Scythian expansion across the Eurasian steppes, a gradual influx of East Eurasian sequences in Western steppes is detected. However, the underlying events behind the genetic admixture in Altai during the Iron Age are still unresolved: 1) whether it was a result of migratory events (eastward firstly, westward secondly), or 2) whether it was a result of a local demographic expansion in a 'contact zone' between European and East Asian people. In the present work, we analyzed the mitochondrial DNA lineages in human remains from Bronze and Iron Age burials of Mongolian Altai. Here we present support to the hypothesis that the gene pool of Iron Age inhabitants of Mongolian Altai was similar to that of western Iron Age Altaians (Russia and Kazakhstan). Thus, this people not only shared the same culture (Pazyryk), but also shared the same genetic east-west population admixture. In turn, Pazyryks appear to have a similar gene pool that current Altaians. Our results further show that Iron Age Altaians displayed mitochondrial lineages already present around Altai region before the Iron Age. This would provide support for a demographic expansion of local people of Altai instead of westward or eastward migratory events, as the demographic event behind the high population genetic admixture and diversity in Central Asia.

Rudny Altai base-metal belt: Localization of massive sulfide mineralization  

NASA Astrophysics Data System (ADS)

The geodynamic evolution, deep structure, and metallogenic regionalization of the Rudny Altai are considered in terms of plate tectonics. The base-metal massive sulfide deposits are genetically related to the group of basalt-andesite-rhyolite sequences formed in rift or island-arc geodynamic setting in the Devonian at the early stage of Hercynian tectogenesis. Taking into account economic reserves of ore and major metals (Cu, Pb, Zn, Au, Ag), as well as lateral and vertical regional metallogenic zoning of the Rudny Altai, the localization of massive sulfide mineralization in ore-bearing structural elements and particular deposits has been specified. The ore productivity of ore-bearing geochronological levels for base metals and the contribution of these levels to the total reserves of the region are characterized in detail. The Rudny Altai basemetal belt is regarded as a continuous ore-bearing structural unit situated in Russia and Kazakhstan.

In 2010, in the ethnic structure of population the percentage of Russians reduced up to 55.7% and of indigenous population increased up to 35.3%. In the Republic positive dynamics of population size is preserved. More than 3/5 of population live in rural territories. The main factor of increase of population size is its natural growth (11 per 1000 of population). The high level of natal V.M.ity and low death rate are observed. In the age structure of population percentage of persons younger than able-bodied age (25.8%) is larger than in persons of older than able-bodied age (15.4%). The tendency of decreasing of percentage of persons younger than able-bodied age and persons of able-bodied age is marked. The process of aging of population is expressed in deterioration of ratio between age groups younger than able-body age and groups of able-bodied age. The low indicator of life expectancy of population if noted. The neoplasms are at third place among causes of death (140.6 per 100 000 of population) after diseases of cardiovascular system and traumas and intoxications. In the structure of disability neoplasms are at second place (12.3%) after diseases of cardiovascular system. The demographic situation has to be taken into account in the process of organization of medical care of population. PMID:25219038

Forest- and agroclimatic potential in the Altai-Sayan ecoregion under climate change during the XXI century  

NASA Astrophysics Data System (ADS)

The Altai Sayan ecoregion (ASE), central Asia, is located in Russia, Mongolia, China and Kazakhstan, within the window 80-102° E and 42-57° N, north of the territory of Tibet. The ASE is a territory with a great variety of landscapes observed at a short distance: from nival and tundra landscapes at highlands, to taiga (dark-needled and light-needled) and subtaiga at middle elevations, to steppes at lower elevations. This southern part of Siberia is known as having a high agroclimatic potential due to favorable climatic and soil resources. Crops of food, forage, and biofuels primarily reside in steppe and forest-steppe zones and are resistant to frequent droughts and the cold climate. Regional studies over the Altai-Sayan ecoregion have already registered a change in climate at the end of the 20th century: January temperatures increased 1-2°C and July temperatures increased 0.7-1.5°C over the last 50 years in the northern portion of ASE; in the southern, more continental portion of ASE, both January and July temperature increased two times greater, 2-4°C and 1.4-3.2°C,0 respectively. Our goal was to model how mountain vegetation in ASE may be altered in a changing climate through the century to the year 2080 and if the agroclimatic potential in the lowlands of ASE may benefit from climate change. We used our montane bioclimatic vegetation model (MontBioCliM) to predict the future vegetation distribution, coupling MontBioCliM with the HadCM3 A2 and B1 climate change scenarios for 2020, 2050, and 2080. MontBioCliM is an envelope-type model that predicts a vegetation type from three climatic indices: growing degree days, base 5C; negative degree days below 0°C; and annual moisture index (a ratio between growing degree days and annual precipitation). Our model runs indicated that by 2080, forest habitats would decrease from 52% to 48% according to the moderate scenario B1 and from 52% to 38% according the harsh A2 scenario. In a warmer climate, grasslands better adapted to hot and dry climates would replace forest which may not be regenerate because of an increased potential for severe and large fires. At the expense of forests, more potential agricultural lands were modeled to appear in new forest-steppe and steppe habitats in foothills and lowlands in ASE. These lands might become suitable for growing traditional crops and introducing new crops. Bioclimatic models determining crop range and regression models determining crop yields were constructed and applied to the above climate change scenarios. Crops were predicted to extend in size and to 2-fold increase. However, due to shortage of water in the future dry climate crops would necessitate irrigation. A new agroclimatic potential of the Altai-Sayan ecoregion was predicted to evolve as climate changes.

Microelements in Lowland Peat of the Northeastern Part of the Altai Mountains  

NASA Astrophysics Data System (ADS)

The greatest areas of bogs are concentrated in the northeastern part of Altai Republic. This place due to a great amount of precipitation and a powerful accumulation of snow with a little drain in comparison with other areas has plenty of bogs. A quarter of all bogs of the Altai Mountains is concentrated here. The bogs develop mainly in the valleys of the rivers. The bogs have a modern origin and the process of bog formation goes at the present time by overgrowing of oxbow and valley lakes, and also by bogging of dry lands - woods and meadows. The area of bogs in relation to the general territory of highlands makes up 1%. Nevertheless, these territories are regarded as complex ecosystems which have economic and scientific value. Let's consider the content of heavy metals in different horizons of the peat under study. The samples of peat of the deposit being examined are characterized by a low total content of zinc: 6,21-44,12 mg/kg. The average amount of zinc in the soils of the Altai Mountains is much larger and makes up 70,3 mg/kg. Quite a significant amount of copper is washed away from peat thickness, its total amount is at the level of 1,58-10,73 mg/kg. The reason for it, probably, lies in the fact that there is a significant amount of fulvic acids in the composition of humic acids which enable the migration of copper beyond the limits of the peat ground in the conditions of the sour environment. A completely different situation is observed in the soils of the Altai mountain area. The biogeochemistry of copper in the soils of the Altai Mountains is thoroughly investigated by M.A.Malgin, A.V.Puzanov, O.A.Yelchininova. Its average amount in the soils of the Altai Mountains makes up 40,6 mg/kg which is twice as much as the abundance ratio in comparison with the world soils. The authors explain this fact as follows: copper is an inactive element in the soils since its ions are easily precipitated by sulfide-, carbonate-, and hydroxide ions, and also are taken up by humic acids of soils. Therefore, notwithstanding the washing type of a water mode, the leaching of copper from the soils of the Altai Mountains is not observed. The amount of cadmium in the investigated lowland peat makes up from 0,12 up to 0,57 mg/kg which is almost two times less than the roughly allowable concentration. Also the monotonous increase of the concentration factor of cadmium upwards on the structure is observed. The peat of the surveyed deposit as far as the amount of cadmium is concerned is actually at the level of the background soils of the Altai mountain area. The amount of lead in the peat under study is not subject to significant fluctuation - from 1,34 up to 10,0 mg/kg which is lower than the average amount characteristic of the soils of the Altai Mountains. The roughly allowable concentration of lead for sour soils makes up 65 mg/kg, therefore the peat under study is non-polluting or lead-free. There is an even distribution of lead in the structure of the axial section. In the distribution of zinc, copper, cadmium, lead in peat thickness there is a contrast between the top layers and the bottom ones. The top layers are characterized by higher concentration of elements. The lowland peat of the northeastern part of Altai Republic in comparison with the West-Siberian peat is characterized by the increased values of zinc and has the same amount of copper and lead.

Paleozoic to Mesozoic Construction of Asia as revealed by the Altai Mountains in NW China  

NASA Astrophysics Data System (ADS)

The Paleozoic growth of Asia was accomplished primarily by the accretion of material between the Siberian, Eastern European, North China and Tarim cratons into the Central Asian Orogenic System (CAOS). The construction of this Asian nucleus is important because it represents a substantial fraction of the continental crust generated in the Phanerozoic; however, the tectonic processes responsible for this growth are poorly understood largely because of a lack of regional data. Previous workers have suggested that the CAOS grew via magmatic addition in the Precambrian to Carboniferous and that the Permian marks the end of tectonic activity associated with the construction of the CAOS. To address this, we determined U-Pb zircon ages and geochemical data of southern Altai plutons and combined these with thermobarometry and Th-Pb monazite and 40Ar/39Ar thermochronology of associated metamorphic rocks. U-Pb ion-microprobe zircon ages reveal major pulses of magmatism in the Ordovician-Devonian and Permian. Deformed plutons and gneisses have ages ranging from 392 ± 17 Ma to 451 ± 14 Ma, whereas unfoliated plutons and dikes have ages between 286 ± 12 and 278 ± 9 Ma. Permian intrusions in the region are often interpreted as anorogenic. Our geochemistry indicates a calc-alkaline signature with a decoupled LIL/HFS slope in extended trace element diagrams and a negative Nb anomaly in both Permian and Devonian-Ordovician plutons, consistent with a subduction zone setting. Amphibolite-grade metamorphic rocks have Permian to Jurassic Th-Pb monazite ages and zircons from associated orthogneisses display rims consistent with Permian metamorphic zircon growth. Metamorphism was immediately followed by exhumation along thrust faults. Permian to Triassic mica and K-feldspar 40Ar/39Ar ages record this cooling. The spatial pattern of cooling ages suggest that exhumation-related deformation initiated to the south adjacent to the Junggar suture in the Permian, but continued into the Triassic farther north. These results suggest NW China records an Ordovician-Devonian arc magmatic history, while contractional deformation associated with final collision and ocean closure is young, occurring in the latest Paleozoic. Closure of the paleo-Asian ocean was accompanied by Permian arc magmatism and younger contractional deformation as northern Asia stabilized in the Mesozoic.

Ancient DNA analysis affirms the canid from Altai as a primitive dog.

The origin of domestic dogs remains controversial, with genetic data indicating a separation between modern dogs and wolves in the Late Pleistocene. However, only a few dog-like fossils are found prior to the Last Glacial Maximum, and it is widely accepted that the dog domestication predates the beginning of agriculture about 10,000 years ago. In order to evaluate the genetic relationship of one of the oldest dogs, we have isolated ancient DNA from the recently described putative 33,000-year old Pleistocene dog from Altai and analysed 413 nucleotides of the mitochondrial control region. Our analyses reveal that the unique haplotype of the Altai dog is more closely related to modern dogs and prehistoric New World canids than it is to contemporary wolves. Further genetic analyses of ancient canids may reveal a more exact date and centre of domestication. PMID:23483925

Late-Paleozoic-Mesozoic deformational and deformation related metamorphic structures of Kuznetsk-Altai region  

NASA Astrophysics Data System (ADS)

Kuznetsk-Altai region is a part of the Central Asian Orogenic Belt. The nature and formation mechanisms of the observed structure of Kuznetsk-Altai region are interpreted by the author as the consequence of convergence of Tuva-Mongolian and Junggar lithospheric block structures and energy of collision interaction between the blocks of crust in Late-Paleozoic-Mesozoic period. Tectonic zoning of Kuznetsk-Altai region is based on the principle of adequate description of geological medium (without methods of 'primary' state recovery). The initial indication of this convergence is the crust thickening in the zone of collision. On the surface the mechanisms of lateral compression form a regional elevation; with this elevation growth the 'mountain roots' start growing. With an approach of blocks an interblock elevation is divided into various fragments, and these fragments interact in the manner of collision. The physical expression of collision mechanisms are periodic pulses of seismic activity. The main tectonic consequence of the block convergence and collision of interblock units is formation of an ensemble of regional structures of the deformation type on the basis of previous 'pre-collision' geological substratum [Chikov et al., 2012]. This ensemble includes: 1) allochthonous and autochthonous blocks of weakly deformed substratum; 2) folded (folded-thrust) systems; 3) dynamic metamorphism zones of regional shears and main faults. Characteristic of the main structures includes: the position of sedimentary, magmatic and PT-metamorphic rocks, the degree of rock dynamometamorphism and variety rock body deformation, as well as the styles and concentrations of mechanic deformations. 1) block terranes have weakly elongated or isometric shape in plane, and they are the systems of block structures of pre-collision substratum separated by the younger zones of interblock deformations. They stand out among the main deformation systems, and the smallest are included into the deformation systems. 2) folded (folded-thrust) deformation systems combine deformation zones with relic lenses of Paleozoid substratum, and predominantly conform systems of the main faults. Despite a high degree of regional deformation the sedimentary-stratified and intrusive-contact relations of geological bodies are stored within the deformation systems, and this differs in the main the collision systems from zones of dynamic metamorphism. 3) regional zones of dynamic metamorphism of Kuznetsk-Altai region are the concentration belts of multiple mechanic deformations and contrast dynamometamorphism of complexes. The formational basis of dynamic metamorphism zones is tectonites of the collision stage. Zones of dynamic metamorphism attract special attention in the structural model of Kuznetsk-Altai region. They not only form the typical tectonic framework of collision sutures, but also contain the main part of ore deposits of this region. Pulse mode of structure formation of Kuznetsk-Altai region is detected. Major collision events in Kuznetsk-Altai region were in the late-Carboniferous-Triassic time (307-310, 295-285, 260-250 and 240-220 Ma). This study was supported by a grant of the Russian Foundation for Basic Research (project nos. 14-05-00117).

[Hygienic assessment of the radiation risk of radon emanation in the Altai Krai].  

PubMed

The unique climatic and geographical location of the Altai Krai determines the specific radiation dose load for the population, which is composed of the complex of radiological indices, the structure of which is largely dependent on the type of locality and, to a greater extent due to the action of radon, which is currently the main source of internal radiation of the population of upland districts and adjacent territories. There was performed a hygienic assessment of the radiation risk and the expected decline in life expectancy and population health due to radon exposure in the model areas of the Altai Krai. To calculate the additional risk there were used some models for radiation risk extrapolation: a risk constant model, model GSF (Jacobi's model), Lubin model (TSE/AGE/WL) and BEIR VI model for smoking and nonsmoking population, as well as the combined model. The lowest values of the radiation risk and the expected decline in life expectancy are typical for Charyshsko-Ust-Kalmanskaya zone, the maximum--for Kuryinsko--Pospelikhinskaya zone. PMID:25051739

Constraining the timing of the most recent cataclysmic flood event from ice-dammed lakes in the Russian Altai Mountains, Siberia, using cosmogenic in situ 10Be  

NASA Astrophysics Data System (ADS)

Ice-dammed lakes were repeatedly formed in intermontane basins in the Russian Altai Mountains throughout the Pleistocene. These cataclysmic outburst floods, caused by ice-dam failures, were documented as Earth's largest flood waves by other geoscientists. Using in situ 10Be, we successfully dated surfaces of flood-associated boulders located in a former lake basin and downvalley from a former ice dam. Our precise surface exposure ages suggest that all boulders were associated with the most recent out of a number of cataclysmic floods that occurred at 15.8 ± 1.8 ka. The field location of the boulders implies that they were deposited by the largest late Pleistocene flood that drained the Chuya-Katun Lake completely following initial dam failure. A published reconstruction of the late glacial paleoenvironment in the vicinity of the former ice dam indicates that dam failure was likely a result of climatically induced downwasting of glaciers. The failure of the ice dam provides more evidence for the timing of widespread warming during the late glacial in southern Russia. This flooding event in the headwaters of the Ob River coincides with a freshwater peak as recorded in isotopic records of the Kara Sea and the Arctic Ocean.

Holocene climate change and peatland dynamics in the Altai Mountains in Northwest China  

NASA Astrophysics Data System (ADS)

Here we present preliminary results from a peat-core record to investigate responses of upland vegetation and peatlands to Holocene climate change in the Altai Mountains. Chronology of a 650-cm-long peat core from the Iron Arshad Khan (IAK) peatland in the western Altai Mountains was controlled by 20 AMS dates on identifiable terrestrial macrofossils, covering the entire Holocene. Lithology results indicate that the peat accumulation initiated at 11 ka (1 ka =1000 cal BP), with a sharp increase in organic matter content to >80%. Plant macrofossil data show a sequence of changes from the peatlands dominated by Cyperaceae before 8.1 ka, to Cyperaceae and brown moss-dominated at 8-4.5 ka, Sphagnum and Cyperaceae-dominated at 4.5-2 ka, and to Cyperaceae-dominated again after 2 ka. Carbon accumulation rates were highest at >40 gC/m2/yr at 8.5-7 ka, more than doubled the Holocene average at the site. Pollen analysis shows the highest tree pollen (mainly from Picea) of up to 59% occurred at 8-6.4 ka, suggesting a warm and wet mid-Holocene 'optimum' climate in the region. Organic matter bulk density shows an increasing trend after 6.4 ka, suggesting increasing cumulative decomposition of accumulated peat. Our multi-proxy data indicate clear responses of peatland species composition, moisture conditions and carbon accumulation to regional climate change. The cooling and drying trend since the mid-Holocene was likely in response to the decrease in summer insolation and in westerly-induced precipitation. Furthermore, our results from this temperate highland peatland may shed new lights on understanding peatland carbon dynamics in northern Eurasia, including the largest peatland basin in West Siberia, as well as Holocene climate changes in central Asia.

Ecological Structure of Recent and Last Glacial Mammalian Faunas in Northern Eurasia: The Case of Altai-Sayan Refugium  

PubMed Central

Pleistocene mammalian communities display unique features which differ from present-day faunas. The paleocommunities were characterized by the extraordinarily large body size of herbivores and predators and by their unique structure consisting of species now inhabiting geographically and ecologically distinct natural zones. These features were probably the result of the unique environmental conditions of ice age ecosystems. To analyze the ecological structure of Last Glacial and Recent mammal communities we classified the species into biome and trophic-size categories, using Principal Component analysis. We found a marked similarity in ecological structure between Recent eastern Altai-Sayan mammalian assemblages and comparable Pleistocene faunas. The composition of Last Glacial and Recent eastern Altai-Sayan assemblages were characterized by the occurrence of large herbivore and predator species associated with steppe, desert and alpine biomes. These three modern biomes harbor most of the surviving Pleistocene mammals. None of the analyzed Palearctic Last Glacial faunas showed affinity to the temperate forest, taiga, or tundra biome. The Eastern part of the Altai-Sayan region could be considered a refugium of the Last Glacial-like mammalian assemblages. Glacial fauna seems to persist up to present in those areas where the forest belt does not separate alpine vegetation from the steppes and deserts. PMID:24454791

[Phylogeography of Altai osmans (Oreoleuciscus sp., Cyprinidae, Pisces) based on sequence variation of the mitochondrial DNA cytochrome b gene].  

PubMed

Representatives of the genus Oreoleuciscus (Altai osmans) from the water bodies of Western Mongolia were examined for sequence polymorphism of the mitochondrial DNA fragment containing the cytochrome b (Cyt-b) gene. A total of 17 sequence variants (haplotypes) were discovered, which formed two clusters, A and B, with nonoverlapping geographic localization. Cluster A included haplotypes of Altai osmans from the Valley of Lakes water bodies. Cluster B consisted of two subclusters, the first of which (B1) united sequence variants of the populations from Hollow of the Great Lakes and the lakes of the Great Altai Range. The second subcluster (B2) was formed by the haplotypes originating from the Hollow of the Lake Uvs, some isolated lakes of the Northwestern Khangay region, and the water bodies of the Arctic Ocean Basin (basins of Selenga and Orchon rivers). Based on the genetic divergence estimates and the radiation time of genetic geographic groups identified, the existence of three allopatric species of Altaic osmans in the genus Oreoleuciscus was substantiated.

[Genetic analysis of the South Altaian population of the Mendur-Sokkon village, Altai Republic].  

PubMed

This study was a continuation of complex research on the gene pool of indigenous Siberian populations conducted at the Institute of Cytology and Genetics, Siberian Division, Russian Academy of Sciences. In the population of South Altaians from the Mendur-Sokkon village, Ust'-Kanskii raion, Altai Republic, polymorphism for the following genetic markers was studied: blood groups ABO, MNSs, Rhesus, Kell, Duffy, and P; erythrocyte acid phosphatase (AcP); phosphoglucomutase 1 (PGM1); haptoglobin (Hp); and transferrin (Tf). The genetic position of South Altaians relative to the populations of the European part of Russia, Siberia, and the Urals was estimated. It was demonstrated that the gene pool of the South Altaian population of Mendur-Sokkon possessed both Caucasoid and Mongoloid genetic characteristics, with the latter prevailing. Genetically, this population is most closely related to Mongols and Nentsis. The genetic distance between South and North Altaians was large; this agreed with earlier genetic data and confirmed anthropological and ethnographic evidence indicating that these two groups had different backgrounds and were at different stages of ethnogenesis.

Environmental changes in the northern Altai during the last millennium documented in Lake Teletskoye pollen record  

NASA Astrophysics Data System (ADS)

A high-resolution pollen record from Lake Teletskoye documents the climate-related vegetation history of the northern Altai Mountain region during the last millennium. Siberian pine taiga with Scots pine, fir, spruce, and birch dominated the vegetation between ca. AD 1050 and 1100. The climate was similar to modern. In the beginning of the 12th century, birch and shrub alder increased. Lowered pollen concentrations and simultaneous peaks in herbs (especially Artemisia and Poaceae), ferns, and charcoal fragments point to colder and more arid climate conditions than before, with frequent fire events. Around AD 1200, regional climate became warmer and more humid than present, as revealed by an increase of Siberian pine and decreases of dry herb taxa and charcoal contents. Climatic conditions were rather stable until ca. AD 1410. An increase of Artemisia pollen may reflect slightly drier climate conditions between AD 1410 and 1560. Increases in Alnus, Betula, Artemisia, and Chenopodiaceae pollen and in charcoal particle contents may reflect further deterioration of climate conditions between AD 1560 and 1810, consistent with the Little Ice Age. After AD 1850 the vegetation gradually approached the modern one, in conjunction with ongoing climate warming.

DNA analysis for section identification of individual Pinus pollen grains from Belukha glacier, Altai Mountains, Russia  

NASA Astrophysics Data System (ADS)

Pollen taxon in sediment samples can be identified by analyzing pollen morphology. Identification of related species based on pollen morphology is difficult and is limited primarily to genus or family. Because pollen grains of various ages are preserved at below 0?°C in glaciers and thus are more likely to remain intact or to suffer little DNA fragmentation, genetic information from such pollen grains should enable identification of plant taxa below the genus level. However, no published studies have attempted detailed identification using DNA sequences obtained from pollen found in glaciers. As a preliminary step, this study attempted to analyze the DNA of Pinus pollen grains extracted from surface snow collected from the Belukha glacier in the Altai Mountains of Russia in the summer of 2003. A 150-bp rpoB fragment from the chloroplast genome in each Pinus pollen grain was amplified by polymerase chain reaction, and DNA products were sequenced to identify them at the section level. A total of 105 pollen grains were used for the test, and sequences were obtained from eight grains. From the sequences obtained, the pollen grains were identified as belonging to the section Quinquefoliae. Trees of the extant species Pinus sibirica in the section Quinquefoliae are currently found surrounding the glacier. The consistency of results for this section suggests that the pollen in the glacier originated from the same Pinus trees as those found in the immediate surroundings.

Central Asian Water Cycle Variability over the past Century from Ice-core Isotope Records (Altai, Tien Shan)  

NASA Astrophysics Data System (ADS)

The Altai and Tien Shan ice cores records are expanding our understanding of the inter-Hemispheric water cycle and climate dynamics: the moisture advection from Atlantic and Pacific Oceans, and from Aral-Caspian closed drainage basin to the Arctic Ocean defining the interaction over time between the westerly jet stream, and the Asian monsoon, Siberian and Tibetan Highs and deciphering local verses regional change over the temperate and high latitudes. The multi-parameter high-resolution (i.e., sub-seasonal) glacio-climatic and environmental records from the upper fifty meter of the 175 m surface to bottom ice core recovered in 2003 from the Belukha snow-firn plateau at 4115 m (Altai Mts.) and the upper 20 m of the 160 m deep ice-core recovered in 2000 from the head of Inylchek Glacier at 5200 m (Tien Shan Mts.) were developed and evaluated. The long-term meteorological, synoptic, dust storm and forest fire records and physical stratigraphy data were the basis for calibration, validation and interpretation. The mean annual snow accumulation on the Inylchek glacier for the period from 1992 to 1998 was found to be 116 g cm-2/yr. Validation of the Altai ice core records through the marker horizon of volcanic eruptions showed monthly accordance in the dating century accumulation ice core records with the mean accumulation rate of 650 g cm-2/yr. The ? 18O, ? D and d excess records showed well-preserved seasonal variation, which is significantly controlled by air temperature, by share of cold/or warm season precipitation amount and origin, transport and recycling of moisture. The ? 18O-? D relationship in the upper 50 m of the Altai ice core records has the same slope to the co-variance as that of the global meteoric water line (i.e., 8), while the Tien Shan ice-core records has lower slope (i.e., 7). The snow accumulation of central Asian glaciers was formed from oceanic precipitation and the moisture originated over Aral-Caspian sources. The Northern Atlantic contributed 15% of moisture, while Black and Eastern Mediterranean Seas 32% to the 20 m Inylchek accumulation. The rest precipitation on the Tien Shan glacier has inter-continental origin. The d-excess show means maximum in winter and minimum in summer in both ice-cores records. About 70% of the Altai snow firn core d-excess records vary within 6% and 15% with maximum of more than 40% within the range from 8% to 13% with the shift to higher values in the upper part of ice core pointing on increased share of moisture recycled over intercontinental Asia. More than half of accumulation on the Altai records had Atlantic Ocean origin. Precipitation from the Arctic and Pacific Oceans had the smallest deuterium excess and their share in total accumulation is increasing. Ice core analysis of the composition of ? 18O reflected different synoptic situations, which will be reconstructed along with air temperature for about the century of ice core records.

Permian hornblende gabbros in the Chinese Altai not from the Tarim mantle plume  

NASA Astrophysics Data System (ADS)

In the Chinese Altai, on the northern side of the Erqis fault, the ~10-m-wide Qiemuerqieke gabbro is composed almost entirely of hornblende and plagioclase. Its relative crystallization sequence is olivine, hornblende, plagioclase, and it shows a narrow compositional range in SiO2 (48.7-50.2 wt%), MgO (6.33-8.54 wt%), FeO (5.27-6.46 wt%), Na2O (3.06-3.71 wt%), and K2O (0.26-0.37 wt%). These contents result in a high Mg# value (68-72) and a low K2O/Na2O ratio of ~0.1. It has (87Sr/86Sr)i ratios of 0.70339-0.70350, ?Nd(t) values of 4.8-6.0, and zircon ?Hf(t) of 11.4-15.8; these values demonstrate a mantle-derived source, and a whole-rock ?18O of ~6.7‰ suggests a mantle wedge origin. The presence of magmatic hornblende suggests a relatively high water fugacity, and the crystallization temperature (715-826 °C) calculated using Ti-in-zircon thermometry is considerably lower than that of a normal mafi c melt but consistent with an origin from a water-bearing magma. The gabbro has a secondary ion mass spectrometry zircon U-Pb age of 276.0 ± 2.1 Ma, which is coeval with the 275 Ma mantle plume in the northern Tarim craton, but the Qiemuerqieke petrological and geochemical data do not indicate an abnormally high mantle temperature or a deep mantle signature, which would commonly characterize a mantle plume source. Our results integrated with published data support a model of juvenile crustal growth by a subduction-related process.

Folded Lithospheric Basins in Central Asia: Altai-Sayan and Tien Shan basins in a folding lithosphere  

NASA Astrophysics Data System (ADS)

Central Asia is a classic example for continental lithospheric folding. In particular, the Altay-Sayan belt in South-Siberia and the Kyrgyz Tien Shan display a special mode of lithospheric deformation, involving decoupled lithospheric mantle folding and upper crustal folding and faulting. A review of the paleostress data and tectono-stratigraphic evolution of the Kurai-Chuya basin in Siberian Altai, Zaisan basin in Kazakh South Altai and Issyk-Kul basin in Kyrgyz Tien Shan suggests that these basins were initiated in an extensional context and later inverted by a combination of fault-controlled deformation and flexural folding. They deformed by a combination of lithospheric buckling inducing surface tilting, uplift and subsidence, together with upper crustal fault-controlled deformation. They are good examples of Folded Lithospheric Basins (FLB) which typically form in a buckling lithosphere. Their characteristic basin fill and symmetry, inner structure, folding wavelength and amplitude, thermal regime and time frame are examined in relation to basement structure, stress field, strain rate, timing of deformation, and compared to existing modelling results. Both regions of active lithospheric folding have a heterogeneous crust with a long history of accretion-collision, subsequently reactivated as a far-field effect of the Indian-Eurasian collision. Thanks to the youthfulness of the tectonic deformation in this region (peak deformation in late Pliocene - early Pleistocene), the surface expression of lithospheric deformation is well documented by the surface topography and superficial tectonic structures.

The paper describes the results of a sociological study of delivery of healthcare in the Republic of Altai to search for ways to improve its quality and to provide access to the local population. Analysis was made with regard to an interdisciplinary, comprehensive approach to considering the range of problems associated with not only the health of local residents and identifying risk factors leading to diseases, but also by determining the possibilities that could promote the minimization of causes that have a considerable impact on the occurrence of diseases and also hamper healthcare delivery in the human settlements of Gornyi Altai, which are difficult of access. The investigation has used sociological and statistical methods. It has been ascertained that the available healthcare forces and means should be today employed at the regional level, by applying the principles of necessary sufficiency in conjunction with the local population's social motivation to be involved in the activity associated with the rendering of medical services. In addition, it is necessary to systemically use mobile medical units as a significant factor for the optimization of medical care to the population living in Russia's regions which are difficult of access.

Present condition of the coniferous undergrowth of forest-tundra ecotone of North-Chuya ridge (Central Altai)  

NASA Astrophysics Data System (ADS)

Investigations of high-mountain regions which are characterized by extreme climate conditions are of current importance since the response of environmental ecosystems to climate changes is clearly expressed there. The work presented was performed on the territory of two mountain glacial basins located on the northern macroslope of North-Chuya ridge (Russia, Central Altai). High-mountain vegetation of the area being considered didn't undergo an anthropogenic impact. It should be noted that investigations of coniferous undergrowth of forest-tundra ecotone of Aktru and Korumdu mountain glacial basins (2200-2500 m ab. s.l.) haven't been conducted before. A climatic representativeness of Aktru basin was proved by numerous data (Tronov et all, 1965, Sevastianov, 1998). The goal of the work was studying of condition and adaptations of young Pinus sibirica Du Tour and Larix sibirica Ledeb. to forest-tundra ecotone conditions. These species form the treeline on many ridges of Central Altai (Kuminova, 1960), including North-Chuya (Timoshok, 2004). It is shown that the number of young Siberian stone pines and larches in the forest-tundra ecotone is not big, Siberian stone pine being found more often than larch. A considerable quantity of young Siberian stone pines grows in sheltered sites (near big stones, boulders, stumps, etc.). During the research period dead young trees have been found in single cases. The maximum percentage of Siberian stone pine trees (42.4%) growing in sheltered sites was registered in Aktru basin on the east-southeast slope whereas on the west-northwest slope the maximum percentage of Siberian stone pines growing in clusters has been revealed (34.4%). Also on the west-northwest slope the maximum quantity of Siberian stone pines that changed their terminal shoots have been found (62.5%). During the investigation young trees with signs of diseases were registered. Chermes (Pineus cembrae Chol.) has been found on shoots and needles. On the west-northwest slope the corresponding damage constitutes about 3.2% of target Siberian stone pine trees. In forest-tundra ecotone of Aktru basin young larches, often single, grow on exposed sites, and theirs stems often change terminal shoots. There are no diseased trees discovered. For Korumdu mountain glacial basin high percentage of Siberian stone pine trees (41.4%) was registered on the west-northwest slope growing in sheltered sites, as well as trees in clusters (7,2%). On this slope 100% of Siberian stone pines change their terminal shoots meanwhile for the east-southeast slope this characteristic constitutes just 57%. Siberian stone pines with diseases have been registered for the west-northwest slope (7.2%). Thus, considering forest-tundra ecotone of North-Chuya ridge one can conclude that the Siberian stone pine undergrowth condition is more viable on east-southeast slopes than on the west-northwest slopes. The larch undergrowth is not as viable as the Siberian stone pine's one. The work presented is supposed to be used as a basis for detecting response and adaptations of high-mountain coniferous undergrowth to regional climate changes. References 1.

Fragments of the Vendian-Paleozoic oceanic crust of the Paleo-Asian Ocean in foldbelts (Altai-Sayan, Central Asia)  

NASA Astrophysics Data System (ADS)

Four main accretion-collision stages of the evolution of the Paleo-Asian ocean have been recognized in Altai-Sayan: 1) Early-Middle Cambrian, 2) Late Cambrian-Early Ordovician, 3) Devonian-Early Carboniferous and 4) Late Paleozoic. The 1st and 2nd stages characterize evolution of the Kuznetsk-Altai island-arc system, which was accreted to the Siberian continent. The third stage refers to two collisional events during the closing of the Paleo-Asian Ocean: the Gondwana-derived Altai-Mongolian terrane collided with the Siberian continent (D3), and the latter collided with the Kazakhstan continent (C2). Each stage was recorded in folded rock units. Paleooceanic crust fragments occur within accretionary wedges and suture zone. Their geological identification was supported by geochemical data. The better studied areas are Kurai and Katun accretionary wedges, Charysh-Terekta shear zone, and Chara ophiolitic suture zone. Identification of the Vendian-Early Carboniferous oceanic crust extended our knowledge about the Paleo-Asian Ocean evolution. The Kurai and Katun accretionary wedges recorded the Vendian-Cambrian stage of the Kuznetsk-Altai island arc evolution. The Charysh-Terekta zone resulted from the Late Devonian collision of the Altai-Mongolian terrane and the Siberian continent. The Chara ophiolitic suture was formed after the Late Carboniferous-Permian collision of the Siberian and Kazakhstan continents. The Kurai accretionary wedge is composed of the tectonic sheets of the Baratal paleoisland and Chagan-Uzun ophiolites. The Katun accretionary wedge involves paleo-oceanic island rock units: limestones, dolomites, siliceous shales, and basaltic flows. The Charysh-Terekta zone is composed of several tectonic lenses (e.g. Zasurin Formation) comprising sandstones, cherts, pillow-basalts, volcanoclastics, and gabbro-diabase sills and dikes. The Chara ophiolitic belt consists of several melange zones with high-pressure metamorphic rocks (metabasaltic rocks) metamorphosed deep-water siliceous sediments, eclogites, amphibolites, glaucophane schists and volcanic-siliceous rocks with radiolarians and conodonts. The geochemical study of metabasaltic rocks from those four entities indicates that they were formed in two major settings: at mid-oceanic ridges and in oceanic islands. The fragments of the oceanic crust of the Paleo-Asian Ocean were involved in accretionary wedges and shear zones as a result of accretion-collision processes and subduction.

Variation, Variability, and the Origin of the Avian Endocranium: Insights from the Anatomy of Alioramus altai (Theropoda: Tyrannosauroidea)  

PubMed Central

The internal braincase anatomy of the holotype of Alioramus altai, a relatively small-bodied tyrannosauroid from the Late Cretaceous of Mongolia, was studied using high-resolution computed tomography. A number of derived characters strengthen the diagnosis of this taxon as both a tyrannosauroid and a unique, new species (e.g., endocranial position of the gasserian ganglion, internal ramification of the facial nerve). Also present are features intermediate between the basal theropod and avialan conditions that optimize as the ancestral condition for Coelurosauria—a diverse group of derived theropods that includes modern birds. The expression of several primitive theropod features as derived character states within Tyrannosauroidea establishes previously unrecognized evolutionary complexity and morphological plasticity at the base of Coelurosauria. It also demonstrates the critical role heterochrony may have played in driving patterns of endocranial variability within the group and potentially reveals stages in the evolution of neuroanatomical development that could not be inferred based solely on developmental observations of the major archosaurian crown clades. We discuss the integration of paleontology with variability studies, especially as applied to the nature of morphological transformations along the phylogenetically long branches that tend to separate the crown clades of major vertebrate groups.

Geochemical study of the Cambrian-Ordovician meta-sedimentary rocks from the northern Altai-Mongolian terrane, northwestern Central Asian Orogenic Belt: Implications on the provenance and tectonic setting  

NASA Astrophysics Data System (ADS)

The Altai-Mongolian terrane (AM) is a key component of the Central Asian Orogenic Belt (CAOB), but its tectonic nature has been poorly constrained. This paper reports geochemical compositions of Cambrian-Ordovician meta-sedimentary rocks from the northern AM to trace their source nature and depositional setting, which in turn place constraints on the geodynamic evolution of the AM. The Cambrian-Ordovician meta-sedimentary rocks from the northern AM show variable major-element compositions, with negative correlation between SiO2 and TiO2, Al2O3, Fe2O3T, MgO and K2O. Their high ICV values (1.18-2.53) and relatively low CIA values (37.9-76.3) indicate that the sediments were immature and probably underwent mild to moderate chemical weathering. The low-SiO2 samples are characterized by relatively restricted SiO2/Al2O3 (mostly 2.60-6.07) and low Rb/Sr ratios (0.02-1.89), implying their proximal deposition without obvious sedimentary sorting and recycling. In contrast, the high-SiO2 samples show much higher SiO2/Al2O3 ratios (15.4-19.9) possibly due to sedimentary sorting and/or silicification. All these samples yield relatively high Al2O3/TiO2 ratios (15.6-22.8), strong LREEs/HREEs differentiation ((La/Yb)N = 4.86-10.7) and obvious negative Eu anomalies (?Eu = 0.61-0.83). Combined with their Th/Sc, Zr/Sc, La/Th and Co/Th ratios comparable with intermediate-acidic magmatic rocks, we infer that these kinds of magmatic rocks served as a major source for the investigated meta-sedimentary rocks. The TiO2, Al2O3 and Fe2O3T + MgO concentrations are mostly higher than typical sediments from passive margin, and the Th/U, La/Sc, Th/Sc, Eu/Eu?, Zr/Hf, Zr/Th and La/Th ratios are quite similar to sediments from continental arcs. These data suggest that the Cambrian-Ordovician meta-sedimentary rocks from the northern AM were most likely deposited in an environment related to a continental arc setting rather than a passive regime. These rocks show strong similarities to their counterparts in the Chinese Altai (CA, southern AM) and Tseel terrane (southeastern extension of the CA in western Mongolia) in terms of geochemical compositions and depositional setting. With combination of recent isotopic studies for detrital zircons, our data suggest that the AM probably represented a coherent accretionary prism along a continental arc in the early Paleozoic.

The Altai earthquake response of the measuring systems of the Sayano-Shushenskaya hydroelectric power station dam on the Yenisei River  

NASA Astrophysics Data System (ADS)

Results of retrospective analysis of in situ observations in the dam foundation and adjacent bank rocks of the Sayano-Shushenskaya hydroelectric power station (SSHPS) during the nucleation and energy release of the Altai earthquake of September 27, 2003, are presented. A group of most reliable precursors of this earthquake is identified in measured parameters monitoring the state of the facility and surrounding bedrock. The correlation is examined between the precursor occurrence time and the energy of the earthquakes recorded in the regional catalog in 1990-2005, in the period of the normal SSHPS operation.

Magmatism and tectonic evolution of the Chinese Altai, NW China: insights from the Paleozoic mafic and felsic intrusions  

NASA Astrophysics Data System (ADS)

The Chinese Altai, as a key segment of the Central Asian Orogenic Belt (CAOB), is dominated by variably deformed and metamorphosed sedimentary rocks, volcanic rocks and plutonic rocks. The plutonic rocks include extensive granites and relatively subordinate mafic intrusions. For instance, mafic dykes in the northwestern region (Habahe area) have an emplacement age of 375.5±4.8Ma and include gabbroic and doleritic dykes. The gabbroic dykes have chondrite-normalized REE patterns similar to N-MORB (La/YbN=0.86~1.1), together with their high ?Nd(t) values (+7.6~+8.1), indicating deriviation from a N-MORB-type depleted asthenospheric mantle. While the doleritic dykes resemble E-MORB (La/YbN= 1.12~2.28) with relatively low ?Nd(t) values (+3.4-+5.4) and high initial 87Sr/86Sr ratios (0.7057-0.7060), suggesting derivation from a mantle wedge metasomatized by slab-derived fluids and/or melts. In contrast, mafic intrusions in the southeastern region (Keketuohai area) occur as a zoned intrusion with an emplacement age of 409±5 Ma, consisting of dunite, olivine gabbro, hornblende gabbro and pyroxene diorite. Their ?Nd(t) values (0 to +2.7) suggest that the parental magma was produced by partial melting of the lithospheric mantle under a high geothermal regime. Zircon U-Pb ages demonstrate that voluminous granitoids were continuously emplaced over more than 30 % area of the Chinese Altai during the period from 447 Ma to 368 Ma with a climax at ca. 400 Ma. Positive ?Hf(t) values (0 to +9) of normal magmatic zircons suggest that the granitoid magmas were derived from juvenile sources. The extensive magmatism at ca. 400 Ma significantly changed the Hf isotopic composition of the magma source by substantial input of juvenile material in a relatively short period. Four representative large S-type granitic intrusions were emplaced from 419 to 393 Ma, consistent with a period of intensive magmatic activities. The S-type granitic magmas were generated by dehydration melting of newly accreted materials, which were possibly brought to at least middle crustal depth by subduction-related activities in an active continental margin. In contrast, Carboniferous rocks were relatively minor and some granodioritic intrusions in the northwestern region have 313±5 Ma emplacement age. They are characterized by distinctively low total REE contents (67-187 ppm) without pronounced negative Eu anomalies and mantle-like whole-rock Nd-Sr isotopic compositions (?Nd(t)=+2.5 to +4.5; (87Sr/86Sr)i =0.7038 to 0.7048) and zircon ?Hf(t) values (+5.93 to +12.9), implying that parental magma was probably derived from an oceanic lithospheric mantle. Magmatism was active continuously from the Early to Middle Paleozoic, and the strongest magmatic activity took place in the Devonian. Mafic and felsic rocks mostly have positive zircon ?Hf(t) values, and show a dramatic change in zircon Hf isotope compositions at ca. 400 Ma, suggesting significant contributions from mantle-derived juvenile materials to the crust. These findings, together with the occurrence of chemically distinctive igneous rocks and the high-T metamorphism, can be collectively accounted for by ridge-trench interaction during the accretionary orogenic process. In contrast, Carboniferous magmatism represents an important transitional episode from subduction-related regime to post-orogenic extension.

Mineralogical and geochemical features of promising types of gold mineralization in the western Altai-Sayany folded region (Russia)  

NASA Astrophysics Data System (ADS)

The western Altai-Sayany folded region is one of the oldest mining regions of Russia. Typical gold deposits are quartz-viens and skarns, which formation is associated with intrusion of island-arc and collision granitoids. Due to the fact that the traditional gold ore base of the region has already been largely worked out, the necessity of prospecting for new gold deposits has arisen. On the basis of available data, one may state that the outlook for the development of gold-mining industry of the Altai-Sayany region is concerned with gold mineralization in weathering crusts, epithermal gold-silver, gold-porhyry and gold-sulfide formations. The total gold resource potential of these object types is estimated by us at the level of 2000 t. The gold mineralization of epithermal gold-silver formation is confined to Early-Middle Devonian volcanic-plutonic belt. Here, gold-bearing zones of beresitization, argillization, sulfidization and silicification are discovered among volcanites. Maximum contents of noble metals are found in quartz-sulfide veins among sulfidized (arsenic pyrite, pyrite, galenite, sphalerite and fahlore, etc.) and silicified volcanic and subvolcanic rocks. Ore zones are marked by anomalously high content of Au, Ag, Pb, Zn, As, Sb, Hg not only in bedrocks, but also in haloes of dispersion in loose deposits. Gold-sulfide mineralization in terrigenous carbonaceous strata is confined to Late Riphean, Early Cambrian and Devonian metamorphosed complexes. This rocks were formed in the marginal sea basins. Metamorphism and repeated tectono-magmatic activation in the region resulted in redistribution and accumulation of gold. Gold-ore zones are marked by intensive silicification and sulfidization and are characterized mostly by occurrences of multiple generations of pyrite and arsenic pyrite. Gold occurs both in free state and in sulphides. Geochemistry of gold-ore zones can be characterized by associated elevated content of As, Ag, Sb, Cu, Hg. Gold-sulfide mineralization in terrigenous-carbonate strata (Karline type) is confined to Vendian and Late Devonian-Carboniferous carbonaceous dolomite and limestone. Formation of such epithermal mineralization is associated with Mesozoic Siberian plume evolution. Gold mineralization is confined to major tectonic zones, it is accompanied by listwenite, jasperoid and argillizated rock as well as barite, polymetal and mercury mineralization. Geochemistry of gold-ore zones can be characterized by associated elevated content of As, Ag, Sb, Pb, Zn, Hg Tl. Gold-porphyritic mineralization is confined to the areas of distribution of small massifs and dyke fields composed of diorite, granitoid, monzonite, and syenitoid. It is significant that gold is closely associated with copper and molybdenum reflecting general regularities in formation of porphyry orogenic systems. Gold-ore zones are accompanied by kalifeldsparization, silicification and sulfidization. The most widely distributed minerals in ore zones are chalcopyrite, bornite, pyrite, molybdenite, fahlores etc. Gold in crusts of weathering is found in Cretaceous-Paleogene clay and clay-rubbly deposits distributed predominantly among Early Cambrian gold-bearing sulfidized vulcanogenic-sedimentary rocks. Average content of gold in the crusts of weathering is 0.5-1.5 g/t. The gold is of high fineness, with little silver admixture, predominantly free, recoverable by gravity separation, fine in some areas, and associated with clay particles.

Mitochondrial DNA variation in the aboriginal populations of the Altai-Baikal region: implications for the genetic history of North Asia and America.  

PubMed

The discovery of mtDNA types common to Asians and Amerinds (types A, B, C, and D) forced investigators to search for those nations of Asia which, though not considered the ancestors of the Amerinds, have retained a close genetic resemblance with them. We collected samples and studied the gene pools of the Turkic-speaking nations of South Siberia: Altaians, Khakassians, Shorians, Tuvinians, Todjins, Tofalars, Sojots, as well as Mongolian-speaking Buryats. The data indicate that nearly all Turkic-speaking nations of Siberia and Central Asia, as well as the Buryats, have types A, B, C, and D in their gene pool. The highest total frequency of these types is observed in the Tuvinians and Sojots. They, as well as the Buryats, also have the lowest frequency of the europeoid types. The most mixed Asian-Europeoid gene pool examined turned out to be that of the Shorians. An important finding was the presence of type X in the Altaians, which had not yet been detected in Asia. As shown by computer analysis, this DNA sequence is not a late European admixture. Rather, the Altai variant X is ancient and can be close to the ancestral form of the variants of contemporary Europeans and Amerinds. The presented results prove that of all nations in Asia, the Turkic-speaking nations living between Altai and Baikal along the Sayan mountains are genetically closest to the Amerinds. PMID:15126280

Atmospheric circulation patterns and geochemistry time series from ice/firn cores and snow samples of central Asian glaciers (Pamir, Tien Shan and Altai).  

NASA Astrophysics Data System (ADS)

Combination of high mountain ice-core isotope-geochemistry, ground based aerosol monitoring, NASA remote sensed and a NOAA atmospheric pressure distribution data were used to receive information on sources of dust/loess transport, their time and spatial extension in modern and pre-industrial time. Hundreds of samples from snow pits and ice/firn cores obtained from central Asian glaciers were collected, processed and analyzed. The NASA RS products address the gap in interpretation of available snow, firn and ice records by providing the spatial resolution necessary for identifying possible local and regional-scale dust sources, transport routes and depositions. NOAA Hypslit program modeled the air back-trajectories allowed to found association between the ice core geochemistry records and aerosol sources. To find the circulation patterns, which are closely associated with geochemistry ice core/snow pit records, the correlation coefficients between the Empirical Orthogonal Functions of the atmospheric circulation patterns and geochemistry time coefficients for first two unrotated scores were computed. The loess / dust storm sources with corresponding geo-chemical composition (trace elements, major ions and dust particles) in western, central and northern Asia were identified: 1. Tajik loess deposition and Iran, Afghanistan /Turkmenistan sands are for the Pamir. For example, the Pamir ice core records that associated with Tajikistan loess deposition are characterized by high concentrations of REEs and Al, high or median content of Ca, and a background S concentration. Samples from the Pamir Mountains differed in having low concentrations of Gadolinium. Occasional intrusions of Chinese loess to Pamir glaciers are not excluded. REE profile of pilot Pamir cores documented one of the most extreme droughts of 2001 and 2002 that developed in south-west Asia. 2. Chinese loess deposition in the Takla Makhan, sands in the Tajikistan Deserts and western Gobi, and dust aerosols from Aral region are for the Tien Shan; 3. Western and central Gobi and Kazakhstan dust are for the Altai. The Aral region is the source of dust aerosol for Altai also. Based on in-situ data in the western Central Asia and Altai ice core records of particle number content there is tendency on decrease of dust storms frequency from the 30th in central and eastern Asia.

Anticlockwise P-T evolution at ?280 Ma recorded from ultrahigh-temperature metapelitic granulite in the Chinese Altai orogenic belt, a possible link with the Tarim mantle plume?  

NASA Astrophysics Data System (ADS)

An ultrahigh-temperature (UHT) metapelitic granulite assemblage consisting of garnet(g)-spinel(sp)-orthopyroxene(opx)-sillimanite(sil)-cordierite(cd)-ilmenite(ilm)-biotite(bi)-plagioclase(pl)-quartz(q) occurs within migmatitic paragneiss near Kalasu in the Chinese Altai, NW China. Textural relations, mineral compositions and P-T estimates, indicate three stages of mineral assemblages: (1) pre-peak prograde stage (M1) consisting of a sp-sil-bearing or sp-opx-bearing inclusion assemblage, with low-Al2O3 contents (4-5 wt.%) in orthopyroxene and P-T conditions of ?7 kbar and ?890 °C, (2) peak UHT stage (M2) comprising a g-opx-cd-bearing coarse-grained assemblage, with high-Al2O3 contents (8-9 wt.%) in orthopyroxene and peak conditions of ?8 kbar and ?970 °C, and (3) post-peak HT stage (M3) containing an oriented opx-bi-sil-bearing assemblage in matrix, with moderate amounts of Al2O3 (6-7 wt.%) in orthopyroxene and P-T conditions of 8-9 kbar and ?870 °C. The three discrete stages define an anticlockwise P-T path involving initial prograde heating and post-peak near isobaric cooling. Such a near isobaric cooling anticlockwise P-T path suggests that UHT metamorphism likely occurred in an overall extensional tectonic setting with associated underplating of mantle-derived mafic magma. A SHRIMP zircon U-Pb age of 278 ± 2 Ma obtained from the metapelitic granulite indicates UHT metamorphism in the Altai orogen occurred during the Permian, coeval with spacially associated mantle-derived mafic intrusions (?280 Ma) and the Tarim mantle plume (?275 Ma). Thus, the Permian UHT metamorphism of the Chinese Altai is likely associated with underplating and heating of mantle-derived mafic magma as a result of the Tarim mantle plume.

A new approach for reconstruction of the Holocene climate in the Mongolian Altai: The high-resolution ?13C records of TOC and pollen complexes in Hoton-Nur Lake sediments  

NASA Astrophysics Data System (ADS)

?13C of total organic carbon (TOC) and pollen grain, TOC, C/N ratio, and ?15N of total organic nitrogen (TON) in a 2.57-m long core from Hoton-Nur Lake in Mongolian Altai have been measured for reconstruction of the Holocene climates. The ?13C values of TOC and pollen carbon have similar average values but different ranges. Pollen ?13C has negative correlation with %AP (arboreal taxa pollen) and positive correlation with %NAP (herbaceous pollen and spores) that are connected with conditions of humidity in the area. Taiga-biome has lighter ?13C than steppe-biome. Hence, pollen ?13C composition is more sensitive to changes of humidity in the analogous spectra than palynotaxonomical structure and ?13C of TOC. Based on our results, the Holocene climates in Mongolian Altai are: (1) dry conditions prior to 11.5 kyr BP; (2) wet conditions between 11.5 and 6.0 kyr BP; (3) a relatively dry/cool episode during 6-4 kyr BP; (4) stable cool and semiarid conditions with moderately effective moisture during the past 4000 years. Two abrupt climatic changes occurred at ˜7.45 kyr BP and ˜11.5 kyr BP might be related to glacial activities. The Holocene climatic trend in Mongolian Altai which is controlled by the Westerlies is similar to the trend of monsoonal climate shown by the Chinese speleothem records as well as the lake/sand dune evidence in the deserts of NW China. The contact of the two climatic systems and shift of the monsoonal boundary during the past need to be further studied.

Extent and timing of paleoglaciation in the Kanas Valley, Altai Mountains, China, based on remote sensing, field investigations and multiple dating methods  

NASA Astrophysics Data System (ADS)

Reconstructions of the timing and extent of past glaciation provide key constraints for paleoclimate and numerical modeling of past glacier behavior. As part of the multinational Central Asian Paleoglaciology Project we are reconstructing the timing and extent of past glaciation along and across a series of mountain ranges in central Asia using consistent methods for mapping, field investigations and numerical dating. Here we report on new findings for the Kanas Valley in northwest China, a large glaciated valley system on the south side of the Altai Mountains. Previous studies have concluded that the Kanas Valley has been shaped by a series of major glacial advances that produced overdeepened basins, a U-shaped valley cross profile, and extensive glacial and glaciofluvial deposits. Existing Optically Stimulated Luminescence (OSL) and Electron Spin Resonance (ESR) dating results suggest major glaciation in the Kanas Valley during Marine Oxygen Isotope Stages (MIS) 3, 5, and 6, but very limited MIS 2 glaciation. Limited MIS 2 glaciation has also been suggested for other parts of central Asia, and this contrasts with extensive MIS 2 glaciation in Europe and North America. Field studies in 2013 provided new evidence for the highest elevation extent of glaciation in the Kanas Valley in the vicinity of the 20-km long Lake Kanas, with the upper limit of distinct erratics on the valley sidewalls indicating past ice thicknesses here up to 1000 m. Upper limits of erratics extending from Lake Kanas to the mapped maximum down-valley extent of glaciation suggest an ice surface slope of 1.8 degrees for the lower half of the paleoglacier in the Kanas Valley, assuming that all the erratics were deposited at the same time. Systematic sampling of glacial erratics, basal till, terminal moraines, glacially eroded bedrock, and glaciofluvial deposits provided material that is being used for cosmogenic radionuclide, OSL and ESR dating of the glacial chronology, and for dating intercomparisons.

Southern blotting.  

PubMed

Southern blotting is the transfer of DNA fragments from an electrophoresis gel to a membrane support, resulting in immobilization of the DNA fragments, so the membrane carries a semipermanent reproduction of the banding pattern of the gel. After immobilization, the DNA can be subjected to hybridization analysis, enabling bands with sequence similarity to a labeled probe to be identified. This unit describes Southern blotting via upward capillary transfer of DNA from an agarose gel onto a nylon or nitrocellulose membrane, and subsequent immobilization by UV irradiation (for nylon) or baking (for nitrocellulose). A Support Protocol describes how to calibrate a UV transilluminator for optimal UV irradiation of a nylon membrane. An alternate protocol details transfer using nylon membranes and an alkaline buffer, and is primarily used with positively charged nylon membranes. A second alternate protocol describes a transfer method based on a different transfer-stack setup. The traditional method of upward capillary transfer of DNA from gel to membrane has certain disadvantages, notably the fact that the gel can become crushed by the weighted filter papers and paper towels that are laid on top of it. This slows down the blotting process and may reduce the amount of DNA that can be transferred. The downward capillary method described in the second alternate protocol is therefore more rapid and can result in more complete transfer. PMID:18432697

Late Paleozoic tectono-metamorphic evolution of the Altai segment of the Central Asian Orogenic Belt: Constraints from metamorphic P-T pseudosection and zircon U-Pb dating of ultra-high-temperature granulite  

NASA Astrophysics Data System (ADS)

Ultra-high-temperature (UHT) granulite-facies rocks offer important constraints on crustal evolution processes and tectonic history of orogens. UHT granulites are generally rare in Phanerozoic orogens. In this study, we investigate the late Paleozoic pelitic UHT granulites from Altai in the western segment of the Central Asian Orogenic Belt (CAOB). The diagnostic minerals in these rocks include high alumina orthopyroxene (Al2O3 up to 9.76 wt.%, and y(opx) = AlVI in orthopyroxene up to 0.21) coexisting with sillimanite and quartz, and low Zn spinel (ZnO = 1.85-2.50 wt.%) overgrowth with quartz. Cordierite corona separates sillimanite from orthopyroxene. The high alumina orthopyroxene is replaced by symplectites of low-alumina orthopyroxene (~ 5.80 wt.% Al2O3) and cordierite. These textural observations are consistent with a significant decompression following the peak UHT metamorphism. Phase equilibrium modeling using pseudosections and the y(opx) isopleths indicate an anti-clockwise P-T path for the exhumation of the Altai orogenic belt. The pre-peak assemblage of spinel + quartz in garnet is stable at high- to ultra-high-temperature and low-pressure conditions (P < 5.8 kbar at T ~ 900 °C). The peak P-T values recorded by high aluminium orthopyroxene is > 940 °C and 7.8 to 10 kbar. Subsequent near-isothermal decompression occurred at 890 to 940 °C and 5 to 6 kbar. The final-stage cooling is recorded at 750 and 800 °C and 4 to 5 kbar accompanied by a decrease in the y(opx) values (0.11-0.12). In the UHT granulite, zircon grains are commonly enclosed within cordierite. The overgrowth rims of the zircon grains yield a weighted mean 206Pb/238U age of 277 ± 2 Ma using LA-ICP-MS zircon dating, which is interpreted to mark the timing of decompression and cooling. We propose that the anti-clockwise P-T path of the UHT granulite in the Altai orogenic belt could be related to an extensional event related to the sinistral strike-slip along the Irtish tectonic belt after the subduction and slab detachment during the convergence of the Kazakhstan-Junggar plate and the Siberian plate.

Southern blotting.  

PubMed

Southern blotting is the transfer of DNA fragments from an electrophoresis gel to a membrane support (the properties and advantages of the different types of membrane, transfer buffer, and transfer method are discussed in detail), resulting in immobilization of the DNA fragments, so the membrane carries a semipermanent reproduction of the banding pattern of the gel. After immobilization, the DNA can be subjected to hybridization analysis, enabling bands with sequence similarity to a labeled probe to be identified. This appendix describes Southern blotting via upward capillary transfer of DNA from an agarose gel onto a nylon or nitrocellulose membrane, using a high-salt transfer buffer to promote binding of DNA to the membrane. With the high-salt buffer, the DNA becomes bound to the membrane during transfer but not permanently immobilized. Immobilization is achieved by UV irradiation (for nylon) or baking (for nitrocellulose). A Support Protocol describes how to calibrate a UV transilluminator for optimal UV irradiation of a nylon membrane. An alternate protocol details transfer using nylon membranes and an alkaline buffer, and is primarily used with positively charged nylon membranes. The advantage of this combination is that no post-transfer immobilization step is required, as the positively charged membrane binds DNA irreversibly under alkaline transfer conditions. The method can also be used with neutral nylon membranes but less DNA will be retained. A second alternate protocol describes a transfer method based on a different transfer-stack setup. The traditional method of upward capillary transfer of DNA from gel to membrane described in the first basic and alternate protocols has certain disadvantages, notably the fact that the gel can become crushed by the weighted filter papers and paper towels that are laid on top of it. This slows down the blotting process and may reduce the amount of DNA that can be transferred. The downward capillary method described in the second alternate protocol is therefore more rapid than the basic protocol and can result in more complete transfer. Although the ease and reliability of capillary transfer methods makes this far and away the most popular system for Southern blotting with agarose gels, it unfortunately does not work with polyacrylamide gels, whose smaller pore size impedes the transverse movement of the DNA molecules. The third alternate protocol describes an electroblotting procedure that is currently the most reliable method for transfer of DNA from a polyacrylamide gel. Dot and slot blotting are also described.

Debris-covered glacial forms and dynamics of glaciers of the Mongun-Taiga mountain massif (Altai-Sayan mountain system).

Mongun-Taiga mountain massif (3970 m) is situated in the intersection of Altai and Sayan mountain ridges. Average annual temperature within the massif is below -2.6°C, annual precipitation 145-300 mm. Glaciation of the massif has total area of 20 km2. Geographers of Saint-Petersburg University study the glaciers and periglacial zone since 1990. Since the maximum of the LIA the glaciers retreat, short stabilizations took place in early 1920-s, mid-1960-s and mid-1980-s. In 1995-2008 glaciation lost 19% of area. Irregular rate of glacial retreat after the LIA lead to formation of 3 groups of debris covered objects. The first group is connected with moraines of LIA (altitude 2650-3000 m). They consist of ice core and debris cover of different thickness. The mechanism of their formation is the following: stabilization of the edges of the glaciers causes accumulation of the debris, they armor the ice, preventing it from melting. When warming starts the exposed part of the glacier grows thinner, the ice under the moraine looses contact with the main body of the glacier. Increased flow of glacial melt water in the last 10 years led to exposure of moraine ice. Some glaciers which supported LIA moraines on the internal side, retreated abruptly in the period of 1995-2008. Moraines lost their stability, they collapse intensely and ice core melts out. This is observed at Seliverstova glacier (2.8 km2). The second group (altitude 2850-2950 m) is situated between LIA moraines and glaciers. It is represented by layers of ice covered by thin (several dozen cm) moraine. Streams along the edges of the layers expose ice to the depth of 2-3 meters in many places. Edges of glaciers on aerial photos of 1965 coincide with the edges of these layers. It proves their glacial origin. Objects of the third group are parts of glaciers that lost their connection with the main glacial masses and turned into dead ice and small cirque glaciers that lost their accumulation area and activity in 1995-2008. The process of armoring of these ice masses is now very active. Rock glaciers of the massif also have glacial genesis but they don't belong to any group because they integrate buried ice of different generations at least from the maximum of the LIA . Periodic cutoff of new masses of buried ice from the glaciers provides continuous alimentation of rock glaciers. We mapped 17 rock glaciers with total area of 5.5 km2. 2 active rock glaciers under valley glaciers Left Mugur and Right Mugur have the shape of tongues cutting through moraines of LIA and extending 350-500 m further down the slope. Activity of these rock glaciers is proved by transverse crevasses, steepness, instability and bareness of frontal ledges, abundance of boulders fallen from these ledges. We estimate the average rate of their advance from the beginning of LIA 0.5-0.7 m/year .

Cenozoic normal faulting and regional doming in the southern Hangay region, Central Mongolia: implications for the origin of the Baikal rift province  

NASA Astrophysics Data System (ADS)

The Hangay Dome in central Mongolia is a mountainous region covering more than 200,000 km 2 with numerous flat-topped peaks over 3000 m that preserve a Late Cretaceous-Paleogene erosion surface. Doming began in the middle Oligocene producing more than 2000 m of regional topographic uplift. The range represents an important kinematic link between the Baikal rift province to the north and Altai transpressional ranges to the south and west. Structural field investigations of major faults visible on satellite imagery indicate that the southern Hangay Dome region is dominated by Late Cenozoic normal faults that bound small half-graben. Most faults are NE-striking and faults at the highest elevations are the most recently active. Most graben appear to be isolated systems that constitute small sediment sinks perched on the flanks and crests of the dome. The first-order feature is the dome itself and most sediment eroded off of the dome is deposited in the Mongolian Valley of Lakes or is carried northwards by the Selenga river and its extensive tributaries. The basement of the dome is a Precambrian craton although the shape and dimensions of the craton are poorly constrained to the north and east. Late Cenozoic uplift of the southern dome region appears to be confined to the area underlain by cratonic basement whereas the Altai region to the south and west is underlain by mechanically weaker Palaeozoic arc and accretionary belts. With respect to the regional northeast directed SHmax, the Hangay craton appears to have acted as a rigid passive indentor focusing Late Cenozoic transpressional deformation around its west and southern margins. Models invoking a Late Cenozoic plume as the driving force for doming and widespread alkaline volcanism on the dome are not strongly supported by geochemical and isotopic data on Neogene-Recent volcanics and the spatial correlation between areas that are domed and older cratonic crust appears too coincidental to be ignored. Convective removal of an overthickened lithospheric root leading to adiabatically decompressed asthenosphere could explain regional doming and volcanism, however major crustal thickening last occurred in the Permian in the southern Hangay region and the time lag between thickening and postulated root removal and plateau uplift (>200 Myr) appears too long. An alternative model is explored based on speculated lithospheric mantle flow patterns driven by India's continued northeastward indentation. It is suggested that lithospheric mantle flow diversion around the overthickened Hangay craton crustal keel could cause lithospheric thinning beneath the craton and passive asthenospheric upwarp leading to regional topographic uplift and decompression melting/alkali volcanism. In general, the angular relationship between Precambrian craton boundaries and the prevailing northeasterly SHmax appears to control the kinematics of late Cenozoic deformation throughout the Hangay, Altai, Sayan and Baikal regions.

The appearance of the elements of the Protopteris floras: Paleogeographic constraints  

NASA Astrophysics Data System (ADS)

The elements of the Protopteris floras were identified in lower Emsian deposits in areas of collision and rift-related volcanism in Gorny Altai, Tuva Trough, Khakassia, Rybinsk Depression, and the eastern Kuznetsk Basin. The appearance of this type of flora in Siberia was accompanied by short-term climatic transitions from humid to arid conditions and periodic shoreline oscillations. The eruptions of volcanoes brought chemical elements and compounds into the atmosphere, which were responsible for mutations in the plants. Natural selection, which was caused by changes in climatic conditions, also played an important role.

Southern hemisphere observations  

NASA Astrophysics Data System (ADS)

Because of insurmountable problems associated with absolute dating, the non-literate cultures of the Southern Hemisphere can contribute little to Applied Historical Astronomy, although Maori traditions document a possible supernova dating to the period 1000-1770 AD. In contrast, the abundant nineteenth century solar, planetary, cometary and stellar observational data provided by Southern Hemisphere professional and amateur observatories can serve as an invaluable mine of information for present-day astronomers seeking to incorporate historical data in their investigations.

Redshifts of southern clusters  

SciTech Connect

New redshifts are presented for 10 rich clusters of galaxies of the Abell et al. (1989) cluster catalog (Abell's southern extension). These are the first results of a survey of southern cluster redshifts, to be completed out to z of about 0.1. In six clusters the redshifts of the first and second brightest galaxy were measured, giving typical differences of about 650 km/sec. This gives confidence in both the identification of the brightest galaxies and the redshift measurement. It is also found that the redshifts agree well with the log (cz)-m10 relationship. 13 refs.

Accretion of southern Alaska  

USGS Publications Warehouse

Paleomagnetic data from southern Alaska indicate that the Wrangellia and Peninsular terranes collided with central Alaska probably by 65 Ma ago and certainly no later than 55 Ma ago. The accretion of these terranes to the mainland was followed by the arrival of the Ghost Rocks volcanic assemblage at the southern margin of Kodiak Island. Poleward movement of these terranes can be explained by rapid motion of the Kula oceanic plate, mainly from 85 to 43 Ma ago, according to recent reconstructions derived from the hot-spot reference frame. After accretion, much of southwestern Alaska underwent a counterclockwise rotation of about 50 ?? as indicated by paleomagnetic poles from volcanic rocks of Late Cretaceous and Early Tertiary age. Compression between North America and Asia during opening of the North Atlantic (68-44 Ma ago) may account for the rotation. ?? 1987.

This SeaWiFS true-color image acquired over Southern Africa on Sept. 4, 2000, shows a thick shroud of smoke and haze blanketing much of the southern half of the continent. The smoke in this scene is being generated by a tremendous number of fires burning over a large area across the countries of Angola, Zambia, Mozambique, Zimbabwe, Botswana, and the Northern Province of South Africa. In this image, the smoke (grey pixels) is easily distinguished from clouds (bright white pixels). Refer to the Images and Data section for a larger scale view of the fires in Southern Africa. Data from both the SeaWiFS and Terra satellites are being used by an international team of scientists participating in the SAFARI field experiment. The objective of SAFARI is to measure the effects of windblown smoke and dust on air quality and the Earth's radiant energy budget. This image was produced using SeaWiFS channels 6, 5, and 1 (centered at 670 nm, 555 nm , and 412 nm, respectively).

Astrophysics in Southern Africa  

E-print Network

The government of South Africa has identified astronomy as a field in which their country has a strategic advantage and is consequently investing very significantly in astronomical infrastructure. South Africa now operates a 10-m class optical telescope, the Southern African Large Telescope (SALT), and is one of two countries short listed to host the Square Kilometre Array (SKA), an ambitious international project to construct a radio telescope with a sensitivity one hundred times that of any existing telescope. The challenge now is to produce an indigenous community of users for these facilities, particularly from among the black population which was severely disadvantaged under the apartheid regime. In this paper I briefly describe the observing facilities in Southern Africa before going on to discuss the various collaborations that are allowing us to use astronomy as a tool for development, and at the same time to train a new generation of astronomers who will be well grounded in the science and linked to their colleagues internationally.

Forecasting southern california earthquakes.  

PubMed

Since 1978 and 1979, California has had a significantly higher frequency of moderate to large earthquakes than in the preceding 25 years. In the past such periods have also been associated with major destructive earthquakes, of magnitude 7 or greater, and the annual probability of occurrence of such an event is now 13 percent in California. The increase in seismicity is associated with a marked deviation in the pattern of strain accumulation, a correlation that is physically plausible. Although great earthquakes (magnitude greater than 7.5) are too infrequent to have clear associations with any pattern of seismicity that is now observed, the San Andreas fault in southern California has accumulated sufficient potential displacement since the last rupture in 1857 to generate a great earthquake along part or all of its length.

These MISR nadir-camera images of southern Florida were acquired on October 18, 2000 (Terra orbit 4446). The view on the left includes Daytona Beach near the top and the Florida Keys at the bottom. Orlando appears as a grayish patch near the top of the image, just to the east of the greenish Lake Apopka, Florida's fourth largest and most polluted lake. On the coast is Cape Canaveral, home of the Kennedy Space Center.

The large body of water in the middle of the land area is Lake Okeechobee. On the western (Gulf of Mexico) coast, Charlotte Harbor and Fort Myers are visible. Along the eastern (Atlantic) coast, partially obscured by clouds, are Palm Beach, Fort Lauderdale, and Miami. Further to the east, the shallow waters and reefs of the Little Bahama and Great Bahama Banks appear in striking blue and green colors.

The two righthand images show the Florida Everglades and the Keys in more detail. Like the lefthand view, the top image is a natural color composite of blue, green, and red band imagery. On the bottom is a false color composite comprised of green, red, and near-infrared data. Near-infrared light is invisible to the human eye. The high reflectance of plants in this part of the electromagnetic spectrum, displayed here in shades of red, is the basis of many satellite-based techniques for detecting and characterizing land surface vegetation.

Beyond Southern Skies  

NASA Astrophysics Data System (ADS)

Beyond Southern Skies tells the story of the planning and construction of the Parkes Telescope in rural New South Wales, Australia and surveys its achievements over the past thirty years. Around this central theme Peter Robertson presents a broader history of radio astronomy, describing its rapid rise to become the respected partner of traditional optical astronomy. The opening up of the radio window on the universe has been one of the most exciting developments in modern science. The technical achievements of the telescope outlined in Peter Robertson's very readable book will be accessible to a general audience. Readers will be fascinated by the lively account of the personalities, politics and controversy that lay behind the decision to build the Parkes Telescope. Since its completion in 1961, the telescope has contributed much to our knowledge of quasars, pulsars, masers, supernova remnants and molecular clouds, as well as the other unusual objects discovered in recent years. During the 1990s the telescope will continue to play a part in our quest to understand the origin and nature of the universe, and our place in it.

In what seemed like the blink of an eye, wildfires ignited in the paper-dry, drought-stricken vegetation of Southern California over the weekend of October 20, 2007, and exploded into massive infernos that forced hundreds of thousands of people to evacuate their communities. Driven by Santa Ana winds, fires grew thousands of acres in just one to two days. The fires sped down from the mountains into the outskirts of coastal cities, including San Diego. Dozens of homes have burned to the ground, and at least one person has died, according to local news reports. Several of the fires were burning completely out of control as of October 22. This image of the fires in California was captured at 1:55 p.m. U.S. Pacific Daylight Time on October 22, 2007. Places where MODIS detected actively burning fires are outlined in red. Thick streamers of smoke unfurl over the Pacific Ocean. The brownish plumes are clouds of dust.

Southern Bald Eagles  

NASA Technical Reports Server (NTRS)

This is one in a series of remarkable photos documenting the daily lives of two of KSC's most famous residents: The Southern Bald Eagles which inhabit an enormous nest on the Kennedy Parkway North. Each fall, the eagles take up winter residence in the nest to breed and raise a new generation. Thanks to a remote-controlled Nikon camera installed yearly in the same pine tree as the nest, the activities of these magnificent birds are recorded on film. This year, a rare and unique event was captured by the camera when a second clutch of eggs was laid, even though a healthy eaglet was born a month earlier. Although it is impossible to determine if it is the same eagles returning each year, the continued tolerance shown by this pair to the human presence seems to indicate that they are the same couple. According to wildlife experts, eight to nine pairs of bald eagles inhabit nests at KSC. The nest on Kennedy Parkway North is particularly well-known because of its huge size and close proximity to a busy road.

A number of organizations have developed to provide assistance to the region, and the Southern Rural Development Center (SRDC), located at Mississippi State University is one such entity. The center's mission statement reflects this sentiment, as it notes its primary directive is "to strengthen the capacity of the region's 29-land grant institutions to address critical contemporary development issues impacting the well-being of people and communities in the rural South." Visitors interested in these issues will find plenty to examine here, as they may elect to view a calendar of germane events (such as regional science conferences and the like), look over a list of their primary focus areas, learn about available funding opportunities, and download any number of policy publications and newsletters which date back to 1993.

Quaternary ledoyoms in the mountains of southern Siberia  

NASA Astrophysics Data System (ADS)

In the 1930s V.P. Nekhoroshev identified intermontane depressions in the Altai mountains that he suspected o be completely filled by glaciers from the surrounding mountains at the time of maximum glaciation. He called such depressions "ledoyoms," or "ice bodies." Some basins already contained lakes when the glaciers advanced into them; in others the valley glaciers impounded lakes when they advanced into the basins. The advancing glaciers in this case became floating or grounded "shelf" glaciers at their lower ends, and some—singly or with neighboring glaciers—armored completely the surface of the "catch lakes." Thus, ledoyoms may develop as: (1) ice only, with no related lake. (2) catch lakes, with both glaciers and related lakes. (3) aufeis ledoyoms; (4) ice-dammed lakes lacking glacial ice cover. During the last glacial maximum some Altai lakes were covered with glacial ice for thousands of years. They consisted of a thick lens of lake water covered by lake ice, aufeis, glacier ice, snow and firn, and became independent centers of glaciation with subradial ice outlets. Possible modern analogs are the subglacial lakes under 3-4 km of glacier ice at Dome B, Dome C, and Vostok Station in Eastern Antarctica.

Tectospheric structure beneath southern Africa  

Microsoft Academic Search

P-wave and S-wave delay times from the broad- band data of the southern Africa seismic experiment have been inverted to obtain three-dimensional images of velocity perturbations in the mantle beneath southern Africa. High velocity mantle roots appear to extend to depths of at least 250 km, and locally to depths of 300 km beneath the Kaap- vaal and Zimbabwe cratons.

Central and southern Africa  

SciTech Connect

Exploration in central and southern Africa continued to expand during 1980. The greatest concentration of activity was in Nigeria. However, there was considerable increase in the level of exploratory work in Cameroon and Congo. Significant new finds have been made in Ivory Coast. Geological and geophysical activity was carried out in 18 of the countries, with those in the western part having the largest share. Seismic work involved 225 party months of operation. Most of this time was spent on land, but marine operations accounted for 73,389 km of new control. Gravity and magnetic data were recorded during the marine surveys, and several large aeromagnetic projects were undertaken to obtain a total of 164,498 line km of data. Exploratory and development drilling accounted for a total of 304 wells and 2,605,044 ft (794,212 m) of hole. The 92 exploratory wells that were drilled resulted in 47 oil and gas discoveries. In development drilling 89% of the 212 wells were successful. At the end of the year, 27 exploratory wells were underway, and 34 development wells were being drilled for a total of 61. Oil production from the countries that this review covers was 918,747,009 bbl in 1980, a drop of about 9% from the previous year. Countries showing a decline in production were Nigeria, Gabon, Cabinda, and Zaire. Increases were recorded in Cameroon, Congo, and Ghana. A new country was added to the list of producers when production from the Belier field in Ivory Coast came on stream. 33 figures, 15 tables.

Kinematic model of southern California  

SciTech Connect

A kinematic model for southern California, based on late-Quaternary slip rates and orientations of major faults in the region, is proposed. Internally consistent motions are determined assuming that these faults bound rigid blocks. Relative to North America, most of California west of the San Andreas fault is moving parallel to the San Andreas fault through the Transverse Ranges and not parallel to the motion of the Pacific plate. The velocities of the blocks are calculated along several paths in southern California that begin in the Mojave Desert and end off the California coast. A path that crosses the western Transverse Ranges accumulates the accepted relative North America-Pacific plate velocity, whereas paths to the north and south result in a significant missing component of motion, implying the existence of a zone of active deformation in southern California. 70 references.

Unprecedented Fires in Southern Africa  

NASA Technical Reports Server (NTRS)

The fires that raged across southern Africa this August and September produced a thick 'river of smoke' over the region. NASA-supported studies currently underway on the event will contribute to improved air pollution policies in the region and a better understanding of its impact on climate change. This year the southern African fire season peaked in early September. The region is subject to some of the highest levels of biomass burning in the world. The heaviest burning was in western Zambia, southern Angola, northern Namibia, and northern Botswana. Some of the blazes had fire fronts 20 miles long that lasted for days. In this animation, multiple fires are burning across the southern part of the African continent in September 2000. The fires, indicated in red, were observed by the Advanced Very High Resolution Radiometer (AVHRR) instrument on board the NOAA-14 satellite. The fires generated large amounts of heat-absorbing aerosols (the dark haze), which were observed with the Earth Probe Total Ozone Mapping Spectrometer (TOMS) instrument. These observations were collected as part of a NASA-supported field campaign called SAFARI 2000 (Southern African Regional Science Initiative). The recent six-week 'dry-season' portion of this experiment was planned to coincide with the annual fires. SAFARI 2000 planners tracked the changing location of fires with daily satellite maps provided by researchers at NASA's Goddard Space Flight Center. 'Every year African biomass burning greatly exceeds the scale of the fires seen this year in the western United States,' says Robert Swap of the University of Virginia, one of the campaign organizers. 'But the southern African fire season we just observed may turn out to be an extreme one even by African standards. It was amazing how quickly this region went up in flames.' The thick haze layer from these fires was heavier than campaign participants had seen in previous field studies in the Amazon Basin and during the Kuwati oil fires. The haze aerosols sampled were more heat-absorbing than expected, which means the haze layer may have a significant warming influence on the region's atmosphere.

Southern Alaska Coastal Relief Model  

NASA Astrophysics Data System (ADS)

The National Geophysical Data Center (NGDC), an office of the National Oceanic and Atmospheric Administration (NOAA), in conjunction with the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado at Boulder, has developed a 24 arc-second integrated bathymetric-topographic digital elevation model of Southern Alaska. This Coastal Relief Model (CRM) was generated from diverse digital datasets that were obtained from NGDC, the United States Geological Survey, and other U.S. and international agencies. The CRM spans 170° to 230° E and 48.5° to 66.5° N, including the Gulf of Alaska, Bering Sea, Aleutian Islands, and Alaska’s largest communities: Anchorage, Fairbanks, and Juneau. The CRM provides a framework for enabling scientists to refine tsunami propagation and ocean circulation modeling through increased resolution of geomorphologic features. It may also be useful for benthic habitat research, weather forecasting, and environmental stewardship. Shaded-relief image of the Southern Alaska Coastal Relief Model.

Mutation detection by Southern blotting.  

PubMed

Following the discovery of the structure of DNA in 1953, it became clear that scientists needed to be able to distinguish different DNA sequences. In 1975, Edward Southern published details of a new method for detecting DNA fragments based upon their specific sequence [corrected]. An indication of the importance of his work is that the technique was eponymously named after him and that subsequent methods based loosely on similar principles were named using a play on his surname (western and northern blot). The simplicity and effectiveness of the technique led to its universal acceptance as a standard method for identification of DNA sequences. In the modern laboratory where turn-around times assume ever greater importance, the process can seem relatively time-consuming. In some cases, this has led to its replacement by more rapid techniques such as long-range PCR. Nevertheless, more than 30 years after its invention, the Southern blot remains a cornerstone of molecular biology. PMID:20938846

Dusty Skies over Southern California  

NASA Technical Reports Server (NTRS)

Southern California's 'Santa Anas' are dry, north-easterly winds having speeds in excess of 25 knots (46 kilometers/hour). Santa Ana conditions are commonly associated with gusts of more than twice this level. These offshore winds usually occur in late fall and winter when a high pressure system forms in the Great Basin between the Sierra Nevadas and the Rocky Mountains. The air warms as it flows downslope from the high plateau, and its speed increases dramatically when forced through narrow canyons and mountain passes. Due to Southern California's uneven terrain, the strength of the winds varies greatly from place to place, and the Santa Anas can be sufficiently strong to pick up surface dust.

This view from the Multi-angle Imaging SpectroRadiometer shows the pattern of airborne dust stirred up by Santa Ana winds on February 9, 2002. The image is from MISR's 70-degree forward-viewing camera, and airborne particulates are especially visible due to the camera's oblique viewing angle. Southeast of the Los Angeles Basin, a swirl of dust, probably blown through the Banning Pass, curves toward the ocean near Dana Point. The largest dust cloud occurs near Ensenada, in Baja California, Mexico. Also visible in this image is a blue-gray smoke plume from a small fire located near the southern flank of Palomar Mountain in Southern California.

This image was acquired during Terra orbit 11423, and represents an area of about 410 kilometers x 511 kilometers.

MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

Comparison of seismotomographic and thermogravitational models with distribution of the seismotectonic deformation orientations for southern Siberia area  

NASA Astrophysics Data System (ADS)

The recent geodynamics of southern Siberia is under influence of external and internal factors. First, fields of tension arise on borders of a large earth's plates during their interaction caused by lateral movement. Second, processes in the sublithospheric part of the upper mantle of the region. To study influence of these factors we carried out the comparison of various geophysical methods results, with taking into account available geological data on a faults structure of the region. The joint analysis included results of seismotomographic modeling, determinations of seismotectonic deformation (STD) principal axes orientation, and data of numerical thermogravitational modeling of upper mantle convection with considering influence on its structure of a local overheat under surrounding thick lithosphere blocks. The 3D model of seismic P-waves anomalies distribution in the upper mantle of southern Siberia and adjacent areas is updated by addition to calculations a new data from the ISC catalog. It is calculated by a technique developed during the previous researches (Koulakov, Bushenkova, 2010). Thickness estimates of a «seismic lithosphere» are made in the same way, as in work (Bushenkova, etc., 2008). The received estimates are used for specification of boundary conditions for a numerical thermogravitational modeling (Chervov, Chernykh, Journal of Engineering Thermophysics, in press). A principal axes STD orientations are calculated on Riznichenko&Kostrov's method by data of focal mechanisms solution about 770 earthquakes with magnitude of 3.5 - 7.3 which have occurred in the crust of Altai-Sayan area from 1970 to 2007. We have executed a comparison of seismotomographic and thermogravitational models with distribution of the principal axes STD orientations for the southern Siberia and adjacent territories. The following features were found. It is possible to observe a tendency to azimuthal change of the principal axes STD orientations along borders of positive and negative seismic velocity anomalies in the obtained seismotomographic model. We observe obvious correlation of the principal exes STD orientations distribution and convection flows distribution in the obtained numerical thermogravitational model of the upper mantle structure. Namely, orientations of an extension are mainly located along descending flow (in the plan), whereas orientations of a shortening - across them respectively. Further with approach to an ascending flow it is possible to observe a tendency to change of the direction of the STD orientations of an extension axes around its center, and on radii - directly over the center of this ascending flow. We consider that, due to stability of the observed tendencies, in other areas with similar block structure of a lithosphere, it will be possible to predict orientations of a principal axes seismotectonic deformations for the subsequent seismic events in similar regions. Work is performed with partial support of the RFBR #13-05-00054 and IP SB RAS #76.

Southern Appalachian Regional Seismic Network  

SciTech Connect

The seismic activity in the southern Appalachian area was monitored by the Southern Appalachian Regional Seismic Network (SARSN) since late 1979 by the Center for Earthquake Research and Information (CERI) at Memphis State University. This network provides good spatial coverage for earthquake locations especially in east Tennessee. The level of activity concentrates more heavily in the Valley and Ridge province of eastern Tennessee, as opposed to the Blue Ridge or Inner Piedmont. The large majority of these events lie between New York - Alabama lineament and the Clingman/Ocoee lineament, magnetic anomalies produced by deep-seated basement structures. Therefore SARSN, even with its wide station spacing, has been able to define the essential first-order seismological characteristics of the Southern Appalachian seismic zone. The focal depths of the southeastern U.S. earthquakes concentrate between 8 and 16 km, occurring principally beneath the Appalachian overthrust. In cross-sectional views, the average seismicity is shallower to the east beneath the Blue Ridge and Piedmont provinces and deeper to the west beneath the Valley and Ridge and the North American craton. Results of recent focal mechanism studies by using the CERI digital earthquake catalog between October, 1986 and December, 1991, indicate that the basement of the Valley and Ridge province is under a horizontal, NE-SW compressive stress. Right-lateral strike-slip faulting on nearly north-south fault planes is preferred because it agrees with the trend of the regional magnetic anomaly pattern.

Coal Mining in Southern Illinois  

NSDL National Science Digital Library

After graduating from high school in 1936, C. William "Doc" Horrell received a $12 camera from his mother. Horrell was immediately bitten by the photography bug, and created a dark room in his mother's walk-in-closet. He attended Southern Illinois Normal University (now the Southern Illinois University Carbondale), and after his time in the armed services, he opened up his own photography studio in Anna, Illinois. In the 1960s, Doc began wandering around southern Illinois to document the region's coal mining industry. Over the next few years, he took thousands of photographs, some of which formed the heart of his 1973 book, "The Land Between the Rivers". The good folks at SIU Carbondale have created this online exhibit to introduce users to Horrell's work. Visitors can make their way through the exhibit, and they may find themselves gravitating to the complete online collection, which contains over 750 items. It's a tremendous find, and it includes images of abandoned coal mining facilities, men at work, and coal trains.

Geothermal resources of southern Idaho  

SciTech Connect

The geothermal resource of southern Idaho as assessed by the U.S. Geological Survey in 1978 is large. Most of the known hydrothermal systems in southern Idaho have calculated reservoir temperatures of less than 150 C. Water from many of these systems is valuable for direct heat applications. A majority of the known and inferred geothermal resources of southern Idaho underlie the Snake River Plain. However, major uncertainties exist concerning the geology and temperatures beneath the plain. The largest hydrothermal system in Idaho is in the Bruneau-Grang View area of the western Snake River Plain with a calculated reservoir temperature of 107 C and an energy of 4.5 x 10 to the 20th power joules. No evidence of higher temperature water associated with this system was found. Although the geology of the eastern Snake River Plain suggests that a large thermal anomaly may underlie this area of the plain, direct evidence of high temperatures was not found. Large volumes of water at temperatures between 90 and 150 C probably exist along the margins of the Snake River Plain and in local areas north and south of the plain.

To say that there are a few earthquake research centers in Southern California is a bit like saying that Chicago sits on a lake of some size. It's a bit of an obvious remark, but given that there are a number of such projects, it's important to take a look at some of the more compelling ones out there. One such important resource is the Southern California Earthquake Data Center, sponsored by a host of organizations, including the California Institute of Technology and the United States Geological Survey. Visitors to the project site can peruse some of its recent work, which includes a clickable map of the region that features information on recent earthquakes in California and Nevada. Equally compelling is the clickable fault map of Southern California where visitors can learn about the local faults and recent activity along each fault. Another key element of the site is the historical earthquake database, which may be of interest to both the general public and those who are studying this area.

Southern rim of Pacific Ocean basin: southern Andes to southern Alps  

SciTech Connect

Between the southern Andes of Tierra del Fuego and the southern Alps of New Zealand lies the least accessible and geologically least explored part of the Pacific Ocean basin. A joint United Kingdom-United States project was initiated in 1983 to elucidate the geologic history and structure of the Pacific margin of Antarctica from the Antarctic Peninsula to Pine Island Bay at approximately lone. 105/sup 0/W. The first season (1983-1984) of this West Antarctic Tectonics Project was spent in the Ellsworth-Whitmore crustal block, and the second (1984-1985) in the Thurston Island crustal block. The project involves structural and general field geology, petrology, geochemistry, paleomagnetism, and airborne geophysics (magnetics and radar ice echo sounding). A final geologic season will be spent in the Pensacola Mountains of the Transantarctic Range in 1987-1988.

Geothermal resources of southern Idaho  

USGS Publications Warehouse

The geothermal resource of southern Idaho as assessed by the U.S. Geological Survey in 1978 is large. Most of the known hydrothermal systems in southern Idaho have calculated reservoir temperatures of less than 150?C. Water from many of these systems is valuable for direct heat applications, but is lower than the temperature of interest for commercial generation of electricity at the present time. Most of the known and inferred geothermal resources of southern Idaho underlie the Snake River Plain. However, major uncertainties exist concerning the geology and temperatures beneath the plain. By far the largest hydrothermal system in Idaho is in the Bruneau-Grand View area of the western Snake River Plain with a calculated reservoir temperature of 107?C and an energy of 4.5? 10 20 joules. No evidence of higher temperature water associated with this system has been found. Although the geology of the eastern Snake River Plain suggests that a large thermal anomaly may underlie this area of the plain, direct evidence of high temperatures has not been found. Large volumes of water at temperatures between 90? and 150?C probably exist along the margins of the Snake River Plain and in local areas north and south of the plain. Areas that appear particularly promising for the occurrence of large high-temperature hydrothermal systems are: the area north of the Snake River Plain and west of the Idaho batholith, the Island Park area, segments of the margins of the eastern Snake River Plain, and the Blackfoot lava field.

Our objectives were to use modem geodetic data, especially those derived from space techniques like Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), and the Global Positioning System (GPS) to infer crustal deformation in southern California and relate it to plate tectonics and earthquake hazard. To do this, we needed to collect some original data, write computer programs to determine positions of survey markers from geodetic observables, interpret time dependent positions in terms of velocity and earthquake caused episodic displacements, and construct a model to explain these velocities and displacements in terms of fault slip and plate movements.

Atmospheric chemistry over southern Africa  

NASA Astrophysics Data System (ADS)

Changing Chemistry in a Changing Climate: Human and Natural Impacts Over Southern Africa (C4-SAR); Midrand, South Africa, 31 May to 3 June 2011 During the southern African dry season, regional haze from mixed industrial pollution, biomass burning aerosol and gases from domestic and grassland fires, and biogenic sources from plants and soils is worsened by a semipermanent atmospheric gyre over the subcontinent. These factors were a driver of several major international field campaigns in the 1990s and early 2000s and attracted many scientists to the region. Some researchers were interested in understanding fundamental processes governing chemistry of the atmosphere and interaction with climate change. Others found favorable conditions for evaluating satellite- derived measurements of atmospheric properties and a changing land surface. With that background in mind a workshop on atmospheric chemistry was held in South Africa. Sponsored by the International Commission on Atmospheric Chemistry and Global Pollution (ICACGP; http://www.icacgp.org/), the workshop received generous support from Eskom, the South African power utility; and the Climatology Research Group of the University of the Witwatersrand, Johannesburg, South Africa.

Southern Africa CTA Site Proposal  

E-print Network

Southern Africa has some of the world's best sites for air Cherenkov telescopes. South Africa has only one viable site, which is south of Sutherland and also close to the Southern African Large Telescope (SALT). This site has very good infrastructure and is easy to access, but only 47% of the night-time has a cloudless sky usable for observations. Namibia, which already hosts the H.E.S.S telescope, has a number of potential sites with much less cloud coverage. The H.E.S.S. site is one of the highest of these sites at 1840 m a.s.l. with about 64% of the night-time cloudless. It also has very low night sky background levels and is relatively close (about 100 km) to Windhoek. Moving further away from Windhoek to the south, the cloud coverage and artificial night sky brightness becomes even less, with the site at Kuibis (between Keetmanshoop and Luderitz) at 1640 m a.s.l. having clear night skies 73% of the time. Even though this site seems remote (being 660 km from Windhoek by road), it is close to the national ...

Southern African AIDS Training Programme.  

PubMed

The Canadian Public Health Association (CPHA) with the Canadian International Development Agency (CIDA), in a little over 2 years, have established a Southern African AIDS Training Programme (SAT) that is effective in developing community-based responses to acquired immunodeficiency syndrome (AIDS). Based in Harare, Zimbabwe, the program provides financial assistance, training, monitoring, and advice and information to 120 project partners. The average grant size is $40,000. In a second phase of the project, SAT will attempt to meet the requests of its partners for more services. Currently, to meet needs for rapid, responsive training, and novel approaches to skill building, SAT has developed a collaborative nongovernmental organization (NGO) initiative, "The School Without Walls". This program identifies and amplifies what has worked effectively for organizations and programs. Other similar organizations and programs learn from these experiences. Site visits, apprenticeships, mentor organizations, and skills-building based on shared problem-diagnosis and resolution are some of the techniques employed. A draft report of the CIDA midterm external evaluation of SAT recommends renewal of the program, resourcing of the program to meet its regional responsibilities, and adoption of "The School Without Walls" as a central strategy for southern Africa.

Airborne Particulates over Southern Africa  

NASA Technical Reports Server (NTRS)

This map shows the abundance of airborne particulates, or aerosols, over Southern Africa during the period August 14 - September 29, 2000. Low particle concentrations are shown in shades of blue, and high concentrations in shades of red. The results were generated from MISR imagery acquired over this time period, and processed using MISR's automated software system. The approach for deriving aerosol amount makes use of the variation of scene brightness and contrast as a function of observation angle. Black areas over the land area correspond to places where a result was not obtained, for example, due to the presence of clouds.

Extensive burning of grass and shrubland for land management and agriculture comprises a principal source of these aerosols. Vegetation availability increases northward, hence the greater abundance of haze and smoke in Angola and southern Zaire. The lower aerosol abundance around Lesotho and southeastern South Africa is consistent with the higher terrain elevations near the Drakensberg Mountains.

MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

Aseismic uplift in southern california.  

PubMed

Preliminary examination of the historic geodetic record has disclosed crustal uplift of 0.15 to 0.25 meter that apparently began around 1960 and has since grown to include at least 12,000 square kilometers of southern California. This uplift extends at least 150 kilometers west-northwestward along the San Andreas Fault from Cajon to Maricopa, southward from the San Andreas into the northern Transverse Ranges, and eastward from Lebec into and including much of western Mojave block. It seems to have grown spasmodically eastward from a center near the junction of the San Andreas and Garlock faults and has occurred largely within an area that has remained virtually aseismic since at least 1932. Although much of this area has been characterized by crustal mobility since at least the turn the century, the described uplift seems to be an unusually large and probably unique event superimposed the existing pattern of continuing deformation.

[Japanese encephalitis in Southern Europe].  

PubMed

In 2012, a fragment of the Japanese encephalitis virus (JEV) genome was isolated from a pool of Culex pipiens mosquitoes caught in 2010 and 2011 in Northern Italy. JEV has a broad geographical distribution in South and Southeast Asia and Oceania, and is the most important cause of viral encephalitis in Asia in humans and also causes encephalitis in horses and fertility problems in pigs. However, recently isolated JEV genome fragments in mosquitoes in Italy could be an indication of repeated introduction of JEV, enzootic circulation of JEV or a related virus in Southern Europe. Until more information is available, Japanese encephalitis remains a travel-related infectious disease for travellers to JEV endemic and epidemic areas outside of Europe. PMID:25090898

Between 1969 and 1991 there were 166,410 births in Southern Israel with 13 maternal deaths (7.8/100,000). In the Jewish population there were 119,130 deliveries with 7 maternal deaths (5.9/100,000), and the Bedouins had 47,280 deliveries with 6 maternal deaths (12.7/100,000). Prenatal care was an important preventive factor. 7 maternal deaths occurred among 151,088 women who had received prenatal care (4.6/100,000), whereas 6 such deaths occurred among 15,322 without prenatal care (39.1/100,000) (P value 0.0005). Ten of the 13 women who died were over 24 years old. Eight of the 13 patients were multiparous. Live births occurred in 6 patients and stillbirths in 5 patients. Hemorrhage, preeclampsia-eclampsia and pulmonary embolism were the leading causes of maternal death. PMID:8512350

Southern Mexico Miocene Magmatic Activity  

NASA Astrophysics Data System (ADS)

Magmatic activity in southern Mexico have been occurred in three important volcanic regions: Los Tuxtlas Volcanic Field (TVF), Chiapanecan Volcanic Arc (CVA), and Tacaná Volcanic Complex (TVC). This activity produce alkaline and calc-alkaline products. The TVF has been active since 7 Ma ago producing Na-alkaline basanite, trachybasalt, and trachyandesite (41 63 wt% SiO2), and calc-alkaline basalts, basaltic-andesites, and andesites (45 63 wt% SiO2). The CVA including El Chichon Volcano produced calc-alkaline magmas varying from andesites to dacites (57 65 wt% SiO2) emitted between 2100 ka ago (Tzontehuitz) to 225 ka and K-alkaline magmas emitted from 1.1 Ma ago (trachybasalt, 46 51 wt% SiO2) to the Recent (trachyandesite, 57 63 wt% SiO2). The TVC emitted calc-alkaline products varying from basaltic-andesite (52 57 wt% SiO2) as mafic enclaves, andesites (57 63 wt% SiO2), and dacites (63 68 wt% SiO2). El Chichón and TVF present slight enrichments in K2O, Na2O, Rb, Sr, Th, U, Cs, and LREE respect to TVC, these are signatures related to subduction environment. The presence of alkaline magmas at El Chichón and TVF correspond to mantle low degree melts that reach the surface along with calc-alkaline lavas due to a tensional stress field that allows their pass to the surface. In the generation of the magmas of southern Mexico three components are involved: mantle partial melting fluids, fluid from subducted lithosphere, and continental crust, likely interacting in different ratios through time and in different proportions from SW to NE.

Implementing a Southern Ocean Observing System  

NASA Astrophysics Data System (ADS)

The Southern Ocean is fundamental to the operation of the Earth system. It is the central connection among the major ocean basins and between the upper and lower layers of the global ocean circulation. It influences global climate and planetary-scale biogeochemical cycles, because the Southern Ocean accounts for half of the annual ocean uptake of anthropogenic carbon from the atmosphere [Rintoul et al., 2001; Le Quéré et al., 2007; Meredith et al., 2012]. The Southern Ocean also supplies nutrients that fertilize the majority of global ocean biological productivity north of 30°S [Sarmiento et al., 2004].

Climatology of extreme winds in southern California  

SciTech Connect

A climatology of annual extreme winds in southern California has been prepared. The climatology includes a description of extreme wind regions, defined on the basis of observed winds and topography. Extreme wind distribution parameters have been estimated for 46 locations using data obtained from the National Climatic Data Center. Probabilities associated with extreme winds have been estimated for these locations. The results of the analysis are generally consistent with previous estimates of extreme winds in southern California. Although in several instances the current estimates are significantly higher than previous estimates. The data examined do not indicate that there has been a significant change in the extreme wind climate of southern California.

Meteor showers of the southern hemisphere  

NASA Astrophysics Data System (ADS)

We present the results of an exhaustive meteor shower search in the southern hemisphere. The underlying data set is a subset of the IMO Video Meteor Database comprising 50,000 single station meteors obtained by three Australian cameras between 2001 and 2012. The detection technique was similar to previous single station analysis. In the data set we find 4 major and 6 minor northern hemisphere meteor showers, and 12 segments of the Antihelion source (including the Northern and Southern Taurids and six streams from the MDC working list). We present details for 14 southern hemisphere showers plus the Centaurid and Puppid-Velid complex, with the ? Aquariids and the Southern ? Aquariids being the strongest southern showers. Two of the showers (?^2 Sagittariids and ? Cetids) were previously unknown and have received preliminary designations by the MDC. Overall we find that the fraction of southern meteor showers south of -30deg declination (roughly 25%) is clearly smaller than the fraction of northern meteor showers north of +30deg declination (more than 50%) obtained in our previous analysis.

Southern Saskatchewan Ticagrelor Registry experience  

PubMed Central

Background As ticagrelor enters into clinical use for acute coronary syndrome, it is important to understand patient/physician behavior in terms of appropriate use, adherence, and event rates. Methods The Southern Saskatchewan Ticagrelor Registry is a prospective, observational, multicenter cohort study that identifies consecutive patients started on ticagrelor. We aimed to evaluate both on- and off-label use, identify characteristics of patients who prematurely stop ticagrelor, and describe patient/physician behavior contributing to inappropriate stoppage of this medication. Results From April 2012 to September 2013, 227 patients were initiated on ticagrelor, with a mean age of 62.2±12.1 years. The participants were 66% men and had a mean follow up of 157.4±111.7 days. Seventy-four patients (32.4%) had off-label indications. Forty-seven patients (20.7%) prematurely stopped ticagrelor and were more likely to be older, women, nonwhite, present with shock, and complain of dyspnea. Twenty-six of the 47 patients stopped ticagrelor inappropriately because of patient nonadherence (18 patients) and physician advice (eight patients). A composite outcome event of death from vascular causes, myocardial infarction, or stroke occurred in 8.8% of the entire cohort and was more likely to occur in those older then 65 years, those presenting with cardiogenic shock, and those who prematurely stopped ticagrelor. Conclusion In this real-world registry of patients started on ticagrelor, a third have off-label indications and a fifth prematurely stop the medication. Premature discontinuation was an independent predictor of major life-threatening bleeding and increased composite event rate of death from vascular causes, myocardial infarction, or stroke.

Unusual Southern Hemisphere tree growth patterns induced by changes in the Southern Annular Mode  

NASA Astrophysics Data System (ADS)

Recent changes in the summer climate of the Southern Hemisphere extra-tropics are primarily related to the dominance of the positive phase of the Southern Annular Mode. This shift in the behaviour of the Southern Annular Mode--essentially a measure of the pressure gradient between Southern Hemisphere mid and high latitudes--has been predominantly induced by polar stratospheric ozone depletion. The concomitant southward expansion of the dry subtropical belts could have consequences for forest growth. Here, we use tree-ring records from over 3,000 trees in South America, Tasmania and New Zealand to identify dominant patterns of tree growth in recent centuries. We show that the foremost patterns of growth between 1950 and 2000 differed significantly from those in the previous 250 years. Specifically, growth was higher than the long-term average in the subalpine forests of Tasmania and New Zealand, but lower in the dry-mesic forests of Patagonia. We further demonstrate that variations in the Southern Annular Mode can explain 12-48% of the tree growth anomalies in the latter half of the twentieth century. Tree-ring-based reconstructions of summer Southern Annular Mode indices suggest that the high frequency of the positive phase since the 1950s is unprecedented in the past 600 years. We propose that changes in the Southern Annular Mode have significantly altered tree growth patterns in the Southern Hemisphere.

Highlighting areas around the rim of southern Lake Michigan, Greenberg's work discusses some state parks and other nature preserves. Serving as a guide, he signals to his readers small outcroppings of nature that have survived and endured, in spite of civilization. Fox example, Mr. Greenberg calls attention to the Indiana Dunes National Lakeshore and State Park. A wet, grassy plain full of plantlife, the park sits north of the industrial southern tip of Lake Michigan, exactly where one might have failed to look for a park that, with the exceptions of the Grand Canyon and Great Smoky Mountains, has more types of plants than any other national park.

Tomographic image of the southern California mantle  

SciTech Connect

P wave teleseismic travel time delays recorded by the Southern California Array are inverted by the method of backprojection tomography to obtain images of variations in the P wave velocity structure to a depth of 750 km. Two major upper mantle features are resolved: One beneath the Transverse Ranges region and another beneath the Salton Trough region. The Transverse Ranges feature appears as a curtainlike, east trending, high-velocity anomaly. This feature is {approximately}60 km thick, extends most deeply on its eastern end (to {approximately}250 km), and attains a maximum velocity {approximately}3% greater than average southern California mantle of the same depth. The Salton Trough feature, which is not as well resolved as the Transverse Ranges feature, is composed of low velocities in the upper 70-100 km. These P wave velocities are depressed 3-4% compared to average southern California mantle. Tests of the inversion indicate the major aspects of the imaged structure are authentic.

The southern California uplift and associated earthquakes  

USGS Publications Warehouse

Southern California earthquakes ??? M5.5 during the period 1955/01/01-1994/01/17 were concentrated along or adjacent to the south flank of the southern California uplift, as defined both at its culmination and following its partial collapse. Spatial clustering of these earthquakes within three more-or-less distinct groups suggests either gaps along the south flank that were previously filled or are yet to be filled. Nearly all of the indicated earthquakes accompanied or followed partial collapse of the uplift, and seismic activity within this regime seems to have been increasing through at least 1994/01/17.

Roses in the Southern Sky  

NASA Astrophysics Data System (ADS)

The two best known satellite galaxies of the Milky Way, the Magellanic Clouds, are located in the southern sky at a distance of about 170,000 light-years. They host many giant nebular complexes with very hot and luminous stars whose intense ultraviolet radiation causes the surrounding interstellar gas to glow. The intricate and colourful nebulae are produced by ionised gas [1] that shines as electrons and positively charged atomic nuclei recombine, emitting a cascade of photons at well defined wavelengths. Such nebulae are called "H II regions", signifying ionised hydrogen, i.e. hydrogen atoms that have lost one electron (protons). Their spectra are characterized by emission lines whose relative intensities carry useful information about the composition of the emitting gas, its temperature, as well as the mechanisms that cause the ionisation. Since the wavelengths of these spectral lines correspond to different colours, these alone are already very informative about the physical conditions of the gas. N44 [2] in the Large Magellanic Cloud is a spectacular example of such a giant H II region. Having observed it in 1999 (see ESO PR Photos 26a-d/99), a team of European astronomers [3] again used the Wide-Field-Imager (WFI) at the MPG/ESO 2.2-m telescope of the La Silla Observatory, pointing this 67-million pixel digital camera to the same sky region in order to provide another striking - and scientifically extremely rich - image of this complex of nebulae. With a size of roughly 1,000 light-years, the peculiar shape of N44 clearly outlines a ring that includes a bright stellar association of about 40 very luminous and bluish stars. These stars are the origin of powerful "stellar winds" that blow away the surrounding gas, piling it up and creating gigantic interstellar bubbles. Such massive stars end their lives as exploding supernovae that expel their outer layers at high speeds, typically about 10,000 km/sec. It is quite likely that some supernovae have already exploded in N44 during the past few million years, thereby "sweeping" away the surrounding gas. Smaller bubbles, filaments, bright knots, and other structures in the gas together testify to the extremely complex structures in this region, kept in continuous motion by the fast outflows from the most massive stars in the area. The new WFI image of N44 The colours reproduced in the new image of N44, shown in PR Photo 31a/03 (with smaller fields in more detail in PR Photos 31b-e/03) sample three strong spectral emission lines. The blue colour is mainly contributed by emission from singly-ionised oxygen atoms (shining at the ultraviolet wavelength 372.7 nm), while the green colour comes from doubly-ionised oxygen atoms (wavelength 500.7 nm). The red colour is due to the H-alpha line of hydrogen (wavelength 656.2 nm), emitted when protons and electrons combine to form hydrogen atoms. The red colour therefore traces the extremely complex distribution of ionised hydrogen within the nebulae while the difference between the blue and the green colour indicates regions of different temperatures: the hotter the gas, the more doubly-ionised oxygen it contains and, hence, the greener the colour is. The composite photo produced in this way approximates the real colours of the nebula. Most of the region appears with a pinkish colour (a mixture of blue and red) since, under the normal temperature conditions that characterize most of this H II region, the red light emitted in the H-alpha line and the blue light emitted in the line of singly-ionised oxygen are more intense than that emitted in the line of the doubly-ionised oxygen (green). However, some regions stand out because of their distinctly greener shade and their high brightness. Each of these regions contains at least one extremely hot star with a temperature somewhere between 30,000 and 70,000 degrees. Its intense ultraviolet radiation heats the surrounding gas to a higher temperature, whereby more oxygen atoms are doubly ionised and the emission of green light is correspondingly stronger, cf. P

Eddy impact on the Southern Ocean ventilation  

NASA Astrophysics Data System (ADS)

This study examines the specific role of mesoscale eddies and coherent structures in the ventilation of the Southern Ocean through the analysis of Lagrangian particle trajectories in a suite of idealized numerical simulations. Being the biggest potential reservoir for heat and atmospheric gases, the Southern Ocean is of great importance in the Earth's climate system. Therefore, the understanding of ventilation, the process establishing communication between the surface mixed layer and the ocean interior, is crucial to quantify the storage of CO2 by the ocean and to improve climate change projections. Idealized numerical simulations of the Southern Ocean at 1/8o resolution are carried out using the NEMO Ocean General Circulation Model. Twin simulations with and without eddies having the same stratification and mean circulation, are considered using several definitions of eddies. The analysis of the differences between such simulations allows examination of the direct effect of eddies on ventilation of the Southern Ocean. The role played by coherent structures is also discussed by looking at the trajectories of particles specifically injected inside individual vortices.

Southern Ocean: Its involvement in global change  

SciTech Connect

Southern Ocean is the site of considerable water mass formation which cools and ventilates the modern world ocean. At the polar front zone, formation of cool, low salinity water sinks and spreads northward at intermediate depths limiting the downward penetration of the thermocline. Within the seasonal sea ice zone and along the margins of Antarctica, convection injects very cold oxygenated water into the deep and bottom ocean. These conditions developed as Antarctica shifted into its present configuration and grew a persistent glacial ice sheet, about 14 million years ago. The potential of the Southern Ocean to ventilate the deep and bottom ocean layers is related to occurrence of polynyas that form within the winter sea ice cover. Global climate changes would be expected to alter the polynya size and frequency. Under greenhouse-induced warming offshore polynyas may become less common as the static stability of the Southern Ocean mixed layer increases. This would diminish the Southern Ocean's cooling influence on the deep layers of the world ocean, resulting in a warmer deep ocean. The fate of coastal polynyas is less clear.

Early German Plans for a Southern Observatory  

NASA Astrophysics Data System (ADS)

As early as the 18th and 19th centuries, French and English observers were active in South Africa. Around the beginning of the 20th century the Heidelberg astronomer Max Wolf (1863-1932) proposed a southern observatory. In 1907 Hermann Carl Vogel (1841-1907), director of the Astrophysical Observatory Potsdam, suggested a southern station in Spain. His ideas for building an observatory in Windhuk for photographing the sky and measuring the solar constant were taken over by the Göttingen astronomers. In 1910 Karl Schwarzschild (1873-1916), after having visited the observatories in America, pointed out the usefulness of an observatory in South West Africa, where it would have better weather than in Germany and also give access to the southern sky. Seeing tests were begun in 1910 by Potsdam astronomers, but WW I stopped the plans. In 1928 Erwin Finlay-Freundlich (1885-1964), inspired by the Hamburg astronomer Walter Baade (1893-1960), worked out a detailed plan for a southern observatory with a reflecting telescope, spectrographs and an astrograph with an objective prism. Paul Guthnick (1879-1947), director of the Berlin observatory, in cooperation with APO Potsdam and Hamburg, made a site survey to Africa in 1929 and found the conditions in Windhuk to be ideal. Observations were started in the 1930s by Berlin and Breslau astronomers, but were stopped by WW II. In the 1950s, astronomers from Hamburg and The Netherlands renewed the discussion in the framework of European cooperation, and this led to the founding of ESO in 1963, as is well described by Blaauw (1991).

Seismic and Eustatic cycles in the southern Apenine deformation front : Case example of Basilicate (Southern Italy)  

NASA Astrophysics Data System (ADS)

Detailed tectonic analyses and geological mapping in muddy fold-belt front is a hard target. Using both fieldwork and GIS software associated to new soil datations of the different marine terrassic levels of the Tarento Gulf (Southern Italy) we were able to re-interprete from an active tectonic point of view the deformation front of southern Apenines. Furthermore by combining our data with the known eustatic curve of the mediteranean sea along the southern italian shore, we were able to decipher the landscape evolution of the southern Apenines deformation front and we are now able to differenciate the geomorphic signal of both active tectonic and eustatic processes and their related geomorphic features on the Tarento Gulf marine terrasses. Therefore the two passed seismic cycle of the Southern Apenine deformation front are revealed herein and appear to be coherent with both a regular intersismic linear creep period (time =240 ka/uplift=70m) and a rapid cosismic uplift (time :10Ka/uplift = 45m). This study give us new inputs to better understand the deformation front of Southern Apenine (Italy) which is of prime importance today in European Geoscience as well as italian "Protezione Civile Nazionale".

A kinematic model of southern California.  

USGS Publications Warehouse

We propose a kinematic model for southern California based on late Quaternary slip rates and orientations of major faults in the region. Internally consistent motions are determined assuming that these faults bound rigid blocks. The velocities of the blocks are calculated along several paths that begin in the Mojave Desert and end off the California coast. A path that crosses the western Transverse Ranges accumulates the accepted relative North America-Pacific plate velocity, whereas paths to the north and south result in a significant missing component of motion. This implies the existence of a zone of active deformation in southern California that is interpreted to include the western Transverse Ranges and northwest trending, predominately strike-slip faults close to the coast both north and south of the Transverse Ranges. Strain on this system accounts for about a third of the total North America- Pacific plate motion. -from Authors

We present the result of a search for southern Galactic Be star candidates within the group of miscellaneous variables of the ASAS-2 catalog of variable stars, using statistical, morphological, photometric, and color criteria. This search lead us to obtain a catalog of 213 new Be star candidates. The I-band light curves of these candidates show outbursts (Type-1 stars) only in 9% of the sample, and stochastic variations (Type-4 stars) in 91% of the sample. We do not find stars showing clear high and low states (Type-2 stars) or showing outbursts and high and low states simultaneously (Type-1/Type-2 stars). Our sample of southern Galactic Be star candidates provide valuable new bright targets for high resolution spectroscopic studies with small/medium size telescopes.

Fire scars and smoke plumes result from biomass burning in the savannas of southern Democratic Republic of Congo. Astronauts aboard the International Space Station observed the seasonal increase in savanna burning, which traditionally peaks in June in southern Democratic Republic of Congo. This image, taken on May 16, 2002, is centered near 8.6S, 27.4 E. These fires, likely the result of human activities, are thought to contribute significant emissions to the atmosphere (Cahoon, et al, 1992). The darker area in the foreground is a more heavily wooded hillside; most burning occurs in the grassier savannas which appear red-brown.

Adjoint Tomography of the Southern California Crust  

NASA Astrophysics Data System (ADS)

Adjoint tomography utilizes 3D simulations of seismic wave propagation in conjunction with a tomographic technique based on adjoint methods. We begin with an initial 3D model of shear and compressional wavespeeds for southern California provided by the Southern California Earthquake Center (SCEC; model CVM-H), extending to a depth of 60~km. We use the spectral-element method to simulate 140 good-quality local earthquakes, each recorded by as many as 160 stations. We compute misfits between observed and synthetic seismograms by using a new automated time-window selection algorithm that picks any time window within which the data and 3D synthetics are reasonably similar (e.g., P, S, Love, and Rayleigh waves). For each record with a measurement, we compute an adjoint source that is used to create an adjoint wavefield. The interaction between the adjoint wavefield and the regular wavefield forms the gradient of the misfit function for one event. These gradients are combined using a source subspace projection method to compute a model update. We present a seismic wavespeed model for the southern California crust and uppermost mantle. Over the course of 16 iterations, we have applied net changes in excess of ± 30% from the initial 3D model. With each iteration, the changes in wavespeeds have improved the data fit, and we are able to include additional seismograms whose fits to the data for previous model iterations were too poor for selection. The tomographic results compare well with surface geology, the most striking features being the low wavespeeds of the southern San Joaquin basin, the high wavespeeds beneath the western Transverse Ranges, the low wavespeeds in the Coast Ranges, the low wavespeeds in the eastern Mojave region, and the sharp contrast at the eastern front of the Sierra Nevada due to volcanism in the Coso Junction area. Several dramatic improvements of three-component seismic waveforms highlight the power of the iterative approach.

[The new migratory deal in Southern Europe].  

PubMed

The author examines migration patterns in Southern Europe during the 1970s and early 1980s, noting particularly the reduction in migration northward from this region. It is noted that "departure potential remains sizable in certain areas of Portugal, Spain, Southern Italy, and most particularly, of Turkey and Yugoslavia. Transoceanic migrations have by no means ceased, as new flows of skilled labor have, since 1974, gone towards Arab states endowed with petrol (oil) revenues. And yet, the paramount fact is most surely the emergence and the proliferation in Greece, Spain, and (especially) in Italy, of basically clandestine (illegal) immigration. This movement is due to the convergence of several factors: economic and demographic disparities between northern and southern shores of the Mediterranean Sea, the sealing-off of borders in Northwestern Europe and the 'carry-over' effect upon nations of 'transit', the extent of the flow of refugees, and--most particularly--the appeal provided by the development, in these new employer countries, of an underground economy accompanied by the extension into industry of the practice of 'undeclared' work. And notwithstanding the series of rules lastly drawn up in Spain and in Greece, such forms of clandestine (unauthorized) migration appear highly likely--to say the least--to persist."

Ground-water provinces of southern Rhodesia  

USGS Publications Warehouse

Ground-water development, utilization, and occurrence in nine ground-water provinces of Southern Rhodesia are summarized in this report. Water obtained from drilled wells for domestic and stock use has played an important part in the social and economic development of Southern Rhodesia from the beginnings of European settlement to the present. Most of the wells obtain water from fractures and weathered zones in crystalline rocks, before recently, there has been an interest in the possibility of obtaining water for irrigation from wells. Studies of the authors indicate that quantities of water sufficient for irrigation can be obtained from alluvial sediments in the S'abi Valley, from Kalahari sands in the western part of the country, are perhaps from aquifers in other areas. The ground-water provinces fall into two groups--those in the crystalline rocks and those in the noncrystalline rocks. Historically, the wells in crystalline rocks, especially the Gold belts province and the Intrusive granites province, have played a major role in supplying water for the needs of man. These provinces, together with two other less important crystalline rock provinces, form the broad arch which constitutes the central core of the country. The noncrystalline rocks overlie and flank the crystalline rocks to the southeast, northwest, and north. The noncrystalline rock provinces, especially the Alluvium-Kalahari province, contain the most productive or potentially productive ground-water reservoirs in Southern Rhodesia and offer promise of supplying water for irrigation and for other purposes.

Industrial Physics---Southern California Style  

NASA Astrophysics Data System (ADS)

Only in Southern California did space-age style really come into its own as a unique expression of Cold War scientific culture. The corporate campuses of General Atomic in San Diego and North American Aviation in Los Angeles perfectly expressed the exhilarating spirit of Southern California's aerospace era, scaling up the residential version of California modernism to industrial proportion. Architects William Pereira and A.C. Martin Jr., in collaboration with their scientific counterparts, fashioned military-industrial `dream factories' for industrial physics that embodied the secret side of the space-age zeitgeist, one the public could only glimpse of in photographs, advertisements, and carefully staged open houses. These laboratories served up archetypes of the California dream for a select audience of scientists, engineers, and military officers, live-action commercials for a lifestyle intended to lure the best and brightest to Southern California. Paradoxically, they hid in plain sight, in the midst of aerospace suburbs, an open secret, at once visible and opaque, the public face of an otherwise invisible empire. Now, at the end of the aerospace era, these places have become an endangered species, difficult to repurpose, on valuable if sometimes highly polluted land. Yet they offer an important reminder of a more confident time when many physicists set their sights on the stars.

Permanent GPS Geodetic Array in Southern California  

NASA Technical Reports Server (NTRS)

The southern California Permanent GPS Geodetic Array (PGGA) was established in the spring of 1990 to evaluate continuous Global Positioning System (GPS) measurements as a new too] for monitoring crustal deformation. Southern California is an ideal location because of the relatively high rate of tectonic deformation, the high probability of intense seismicity, the long history of conventional and space geodetic measurements, and the availability of a well developed infrastructure to support continuous operations. Within several months of the start of regular operations, the PGGA recorded far-field coseismic displacements induced by the June 28, 1992 (M(sub w)=7.3), Landers earthquake, the largest magnitude earthquake in California in the past 40 years and the first one to be recorded by a continuous GPS array. Only nineteen months later, on 17 January 1994, the PGGA recorded coseismic displacements for the strongest earthquake to strike the Los Angeles basin in two decades, the (M(sub e)=6.7) Northridge earthquake. At the time of the Landers earthquake, only seven continuous GPS sites were operating in southern California; by the beginning of 1994, three more sites had been added to the array. However, only a pair of sites were situated in the Los Angeles basin. The destruction caused by the Northridge earthquake spurred a fourfold increase in the number of continuous GPS sites in southern California within 2 years of this event. The PGGA is now the regional component of the Southern California Integrated GPS Network (SCIGN), a major ongoing densification of continuous GPS sites, with a concentration in the Los Angeles metropolitan region. Continuous GPS provides temporally dense measurements of surface displacements induced by crustal deformation processes including interseismic, coseismic, postseismic, and aseismic deformation and the potential for detecting anomalous events such as preseismic deformation and interseismic strain variations. Although strain meters yield much higher short-term resolution to a period of about 1 year, a single continuous GPS site is significantly less expensive than a single strain meter and probably has better long-term stability beyond a 1-year period. Compared to less frequent field measurements, continuous GPS provides the means to better characterize the errors in GPS position measurements and thereby obtain more realistic estimates of derived parameters such as site velocities.

Ecology of southern ocean pack ice.  

PubMed

Around Antarctica the annual five-fold growth and decay of sea ice is the most prominent physical process and has a profound impact on marine life there. In winter the pack ice canopy extends to cover almost 20 million square kilometres--some 8% of the southern hemisphere and an area larger than the Antarctic continent itself (13.2 million square kilometres)--and is one of the largest, most dynamic ecosystems on earth. Biological activity is associated with all physical components of the sea-ice system: the sea-ice surface; the internal sea-ice matrix and brine channel system; the underside of sea ice and the waters in the vicinity of sea ice that are modified by the presence of sea ice. Microbial and microalgal communities proliferate on and within sea ice and are grazed by a wide range of proto- and macrozooplankton that inhabit the sea ice in large concentrations. Grazing organisms also exploit biogenic material released from the sea ice at ice break-up or melt. Although rates of primary production in the underlying water column are often low because of shading by sea-ice cover, sea ice itself forms a substratum that provides standing stocks of bacteria, algae and grazers significantly higher than those in ice-free areas. Decay of sea ice in summer releases particulate and dissolved organic matter to the water column, playing a major role in biogeochemical cycling as well as seeding water column phytoplankton blooms. Numerous zooplankton species graze sea-ice algae, benefiting additionally because the overlying sea-ice ceiling provides a refuge from surface predators. Sea ice is an important nursery habitat for Antarctic krill, the pivotal species in the Southern Ocean marine ecosystem. Some deep-water fish migrate to shallow depths beneath sea ice to exploit the elevated concentrations of some zooplankton there. The increased secondary production associated with pack ice and the sea-ice edge is exploited by many higher predators, with seals, seabirds and whales aggregating there. As a result, much of the Southern Ocean pelagic whaling was concentrated at the edge of the marginal ice zone. The extent and duration of sea ice fluctuate periodically under the influence of global climatic phenomena including the El Niño Southern Oscillation. Life cycles of some associated species may reflect this periodicity. With evidence for climatic warming in some regions of Antarctica, there is concern that ecosystem change may be induced by changes in sea-ice extent. The relative abundance of krill and salps appears to change interannually with sea-ice extent, and in warm years, when salps proliferate, krill are scarce and dependent predators suffer severely. Further research on the Southern Ocean sea-ice system is required, not only to further our basic understanding of the ecology, but also to provide ecosystem managers with the information necessary for the development of strategies in response to short- and medium-term environmental changes in Antarctica. Technological advances are delivering new sampling platforms such as autonomous underwater vehicles that are improving vastly our ability to sample the Antarctic under sea-ice environment. Data from such platforms will enhance greatly our understanding of the globally important Southern Ocean sea-ice ecosystem. PMID:12154613

Southern Ocean Response to NADW Changes  

NASA Technical Reports Server (NTRS)

The possibility of North Atlantic Deep Water (NADW) changes in both past and future climates has raised the issue of how the Southern Ocean would respond. Recent experiments with the GISS coupled atmosphere-ocean model have shown that a "bipolar see-saw" between NADW production and Antarctic Bottom Water (AABW) production in the Weddell Sea can occur in conjunction with freshening of the North Atlantic. However, this effect operates not through a slow ocean response but via a rapid atmospheric mechanism. As NADW reduces, colder temperatures in the North Atlantic, and Northern Hemisphere in general, are associated with higher surface pressure (increased atmospheric mass). Reduced mass in the Southern Hemisphere occurs in response, with lower pressure over the South Pole (an EOF #1 effect, the "high phase" of the Antarctic Oscillation).The lower pressure is associated with stronger west winds that generate an intensified Antarctic Circumpolar Current (ACC), which leads to longitudinal heat divergence in the South Atlantic (and heat convergence in the Southern Indian Ocean). Colder temperatures in the Weddell Sea region lead to sea ice growth, increased salinity and surface water density, and greater Weddell Sea Bottom Water production. Increased poleward transport of heat occurs in the South Atlantic in conjunction with increased bottom water production, but its convergence at high latitudes is not sufficient to offset the longitudinal heat divergence due to the intensified ACC. The colder temperatures at high latitudes in the South Atlantic increase the latitudinal temperature gradient, baroclinic instability, eddy energy and eddy poleward transport of momentum, helping to maintain the lower pressure over the pole in an interactive manner. The heat flux convergence in the Indian Ocean provides a warming tendency in that region, and overall global production of AABW remains unchanged. These results have implications for the interpretation of the ice core records of the last deglaciation, but may also be relevant for changes during the Holocene and perhaps even in response to increased CO2 forcing,

Ecology of rabies in Southern Rhodesia  

PubMed Central

The spread of rabies since 1950 in Southern Rhodesia is described, and its probable causes analysed; the outbreak is attributed chiefly to the vast domestic-dog population, but cases have been noted among many other species of animal. The difficulties encountered in enforcing general control measures are discussed; however, the advent of Flury-strain avianized vaccine has allowed of a successful inoculation campaign which, in spite of some failure in immunization, is satisfactorily controlling the disease in most of the areas involved.

River Knick Points of Southern Africa  

NASA Astrophysics Data System (ADS)

Successful interpretation of the longitudinal profiles of rivers in southern Africa requires identification of the relative roles of bedrock geology, tectonics, river capture history, climatic change and eustasy. Knick points, expressed as waterfalls or as changes in gradient, are examined for the Kunene, Orange, Zambezi and Shire Rivers utilising Shuttle Imaging Radar topographic data, Gtopo 30 topographic data, Hydro 1K drainage data, satellite imagery, zoogeography and fieldwork. The results provide insights into what can, and cannot, be inferred about the uplift history of Africa.

Ethnobotanical remarks on Central and Southern Italy  

PubMed Central

Background The present paper is a brief survey on the ethnobotanical works published by the Authors since 1981, concerning the research carried out in some southern and central Italian regions. Before Roman domination these territories were first inhabited by local people, while the southern areas were colonized by the Greeks. These different cultural contributions left certain traces, both in the toponyms and in the vernacular names of the plants and, more generally, in the culture as a whole. Methods Field data were collected through open interviews, mainly of farmers, shepherds and elderly people, born or living in these areas for a long time. Voucher specimens of collected plants are preserved in the respective herbaria of the Authors and in the herbarium of "Roma Tre" University. Important contributions have been made by several students native to the areas under consideration. A comparative analysis with local specific ethnobotanical literature was carried out. Results The paper reports several examples concerning human and veterinary popular medicine and in addition some anti-parasitic, nutraceutic, dye and miscellaneous uses are also described. Moreover vernacular names and toponyms are cited. Eight regions of central and southern Italy (particularly Latium, Abruzzo, Marche and Basilicata) were investigated and the data obtained are presented in 32 papers. Most of the species of ethnobotanical interest have been listed in Latium (368 species), Marche (274) and Abruzzo (203). The paper also highlights particularly interesting aspects or uses not previously described in the specific ethnobotanical literature. Conclusion Phyto-therapy in central and southern Italy is nowadays practised by a few elderly people who resort to medicinal plants only for mild complaints (on the contrary food uses are still commonly practised). Nowadays therapeutic uses, unlike in the past, are less closely or not at all linked to ritual aspects. Several plants deserve to be taken into consideration not only from the anthropological or cultural point of view, but also for further phyto-chemical investigation. Our studies, as well as those of other authors, try to provide an original picture of the local ethno-biodiversity. PMID:17537240

Fifteen species of parasites including Haemaphysalis leporispalustris, Ixodes dentatus, Amblyomma americanum, Cediopsylla simplex, Odontopsyllus multispinosus, Cuterebra sp., Obeliscoides cuniculi, Trichostrongylus calcaratus, Trichostrongylus affinis, Longistriata noviberiae, Dermatoxys veligera, Trichuris sp., Mosgovoyia sp., Taenia pisiformis, and Hasstilesia tricolor as well as coccidia oocysts were collected from 96 cottontail rabbits (Sylvilagus floridanus) confined to a pen in southern Illinois in 1983 and 1984. The diversity of parasites and the intensities of infections were similar to published reports on free-ranging populations. Most variations in parasite abundances were attributable to season. Few lesions were seen in association with parasitism. PMID:1491303

The normal choroidal thickness in southern Thailand  

PubMed Central

Objective To investigate the association between subfoveal choroidal thickness in healthy southern Thailand volunteers and age, axial length, and refractive error. Subjects and methods This was a prospective cross-sectional case series. A total of 210 eyes of 105 healthy volunteers (86 women, age 23–83 years) in southern Thailand were examined with enhanced depth-imaging optical coherence tomography. Subjects with systemic diseases that may affect the choroidal vascular blood vessels, such as diabetes, impaired renal function, and hypertension, were excluded. Refractive error and axial length were measured by autorefractometry and an IOLMaster, respectively. Subfoveal choroidal thickness was measured from the outer border of the retinal pigment epithelium to the inner scleral border in the subfoveal area. Results The mean subfoveal choroidal thickness was 279.4±75.49 ?m, and the mean age was 46.4±16.45 years. Subfoveal choroidal thickness was negatively correlated with age (r2=0.33, P<0.0001) and axial length (r2=0.02, P<0.02). Multivariable regression analysis showed subfoveal choroidal thickness was positively and negatively correlated with a spherical equivalent refractive error and axial length, respectively, when adjusted for age. Conclusion Age is the most important factor in choroidal thickness rather than axial length and refractive error. Subfoval choroidal thickness was decreased 2.67 ?m every year and 14.59 ?m with 1 mm increase in axial length.

SkyMapper: Surveying the Southern Sky  

NASA Astrophysics Data System (ADS)

SkyMapper is a 1.3m telescope built by the Australian National University as a replacement for the Great Melbourne Telescope lost in the fires that destroyed Mt Stromlo Observatory in 2003. The telescope features an 8sq-degree FOV, which when coupled with a new 16kx16k array, yields 5.7sq-degree sampled at 0.5" per pixel. SkyMapper is undertaking a comprehensive 6-colour, 6-epoch survey of the southern celestial hemisphere - the Southern Sky Survey, as well as a shallow full hemispheric survey to provide photometric and astrometric calibrations to 16mag. Additional time will be used to undertake a limited number of other science programs, including a supernova survey that will help imprive Dark Energy constraints. In addition to reviewing the telescope and its surveys, I will show the first results of the telescope, and discuss how others can work with our team and use the SkyMapper dataset on their own scientific programs.

Wood energy in eastern and southern Africa  

SciTech Connect

This paper has outlined a learning curve in dealing with the wood energy situation in eastern and southern Africa. The curve began in total ignorance when wood energy was not considered part of the energy problem. Dominance of wood fuel, throughout the region, became immediately apparent on calculation of national energy balances. The discovery of this other energy crisis'' was, again, to prove that a little knowledge is a dangerous thing, since the emphasis on project intervention was at a national, not local, level. In evaluating the success and failure of energy intervention strategies it was increasingly apparent that the wood energy problem was but another symptom of the problems of subsistence production in Africa. Wood energy, in effect, was simply the rubbish that was left from a wider utilization of biomass, and trying to grow woodfuel per se, especially as a full-price monetary good, was impossible so long as the major relationships and the subsistence system remained outside the market. The failures, however, have allowed the identification of a range of methods for woody biomass intervention in eastern and southern Africa, from which wood energy could be an offtake.

Southern Ocean carbon trends: Sensitivity to methods  

NASA Astrophysics Data System (ADS)

Southern Ocean is highly under-sampled with respect to variables needed to assess trends in air-sea carbon dioxide fluxes. Multiple investigators have made use of sparse measurements of surface ocean partial pressure of CO2 (pCO2), but there remains a lack of consensus as to recent trends in the carbon sink here. We analyze impacts of specific methodological choices on pCO2 trends, with a focus on regional binning, time series length, and spatial biases. We find the most robust approach to include binning based on geographic areas, the removal of spatial gradients in climatological pCO2, the use of annual-average data, and the consideration of trends across multiple combinations of start and end years. Applying this approach, we find that Southern Ocean carbon uptake slowed from about 1990 to 2006 and subsequently strengthened from 2007 to 2010. More data are needed to reduce uncertainties and increase our ability to diagnose change in the carbon sink.

Megaliths and Neolithic astronomy in southern Egypt  

NASA Astrophysics Data System (ADS)

The Sahara west of the Nile in southern Egypt was hyperarid and unoccupied during most of the Late Pleistocene epoch. About 11,000 years ago the summer monsoons of central Africa moved into Egypt, and temporary lakes or playas were formed. The Nabta Playa depression, which is one of the largest in southern Egypt, is a kidney-shaped basin of roughly 10km by 7km in area. We report the discovery of megalithic alignments and stone circles next to locations of Middle and Late Neolithic communities at Nabta, which suggest the early development of a complex society. The southward shift of the monsoons in the Late Neolithic age rendered the area once again hyperarid and uninhabitable some 4,800 radiocarbon years before the present (years BP). This well-determined date establishes that the ceremonial complex of Nabta, which has alignments to cardinal and solstitial directions, was a very early megalithic expression of ideology and astronomy. Five megalithic alignments within the playa deposits radiate outwards from megalithic structures, which may have been funerary structures. The organization of the megaliths suggests a symbolic geometry that integrated death, water, and the Sun. An exodus from the Nubian Desert at ~4,800 years BP may have stimulated social differentiation and cultural complexity in predynastic Upper Egypt.

CHANGES IN SNOWFALL IN THE SOUTHERN SIERRA  

E-print Network

A time series (1916–2009) of annual snowfall totals for Huntington Lake (HL, elev. 2141 m) in the southern Sierra Nevada of California is reconstructed. A reconstruction is (a) necessary because HL data after 1972 are mostly missing and (b) possible because nearby stations reveal high correlations with HL, two above 0.90. The results show mean annual snowfall in HL is 624 cm with an insignificant trend of +0.5 cm (+0.08%) ±13.1 cm decade ?1. Similar positive but insignificant trends for spring snowfall were also calculated. Annual stream flow and precipitation trends for the region again were insignificantly positive for the same period. Snow-water-equivalent comparisons, measured on 1 Apr since 1930 at 26 sites and since 1950 at 45, show similar small, mostly positive, and insignificant trends. These results combined with published temperature time series, which also reveal no significant trends, form a consistent picture of no remarkable long-term changes in the snowfall of this area and elevation of the southern Sierra Nevada of California since the early 20 th century.

Neo-Alpine evolution of the Southern Eastern Alps  

Microsoft Academic Search

The Eastern Southern Alps, located to the east of the N Giudicarie Line, have been originated by polyphase compressional evolution of Tertiary age. The oldest structural system corresponds to the Mesoalpine (Eocene) and early Neoalpine (Oligomiocene) compressional events, which originated the Dinaric system (NW–SE trending) present in the NE side of the Southern Alps. The subsequent tectonic belt is the

Transient tracer applications in the Southern Ocean  

NASA Astrophysics Data System (ADS)

Transient tracers can be used to constrain the Inverse-Gaussian transit time distribution (IG-TTD) and thus provide information about ocean ventilation. Individual transient tracers have different time and application ranges which are defined by their atmospheric history (chronological transient tracers) or their decay rate (radioactive transient tracers). The classification ranges from tracers for highly ventilated water masses, e.g. sulfur hexafluoride (SF6), the decay of Tritium (?3H) and to some extent also dichlorodifluoromethane (CFC-12) to tracers for less ventilated deep ocean basins, e.g. CFC-12, Argon-39 (39Ar) and radiocarbon (14C). The IG-TTD can be empirically constrained by using transient tracer couples with sufficiently different input functions. Each tracer couple has specific characteristics which influence the application limit of the IG-TTD. Here we provide an overview of commonly used transient tracer couples and their validity areas within the IG-TTD by using the concept of tracer age differences (TAD). New measured CFC-12 and SF6 data from a section along 10° E in the Southern Ocean in 2012 are presented. These are combined with a similar data set of 1998 along 6° E in the Southern Ocean as well as with 39Ar data from the early 1980s in the western Atlantic Ocean and the Weddell Sea for investigating the application limit of the IG-TTD and to analyze changes in ventilation in the Southern Ocean. We found that the IG-TTD can be constrained south to 46° S which corresponds to the Subantarctic Front (SAF) denoting the application limit. The constrained IG-TTD north of the SAF shows a slight increase in mean ages between 1998 and 2012 in the upper 1200 m between 42-46° S. The absence of SF6 inhibits ventilation analyses below this depth. The time lag analysis between the 1998 and 2012 data shows an increase in ventilation down to 1000 m and a steady ventilation between 2000 m-bottom south of the SAF between 51-55° S.

Evaluation of network RTK in southern Ontario  

NASA Astrophysics Data System (ADS)

Network Real-Time Kinematic (RTK) has become popular in the past decade as an efficient method of precise, real-time positioning. Its relatively low cost and ease-of-use makes it a good candidate to replace static relative Global Positioning System (GPS) in, e.g., land surveying. A lack of previous studies aroused the interest of the Ministry of Transportation of Ontario (MTO) to request York University to complete a comprehensive study of the performance of network RTK in southern Ontario and whether it is a suitable method for MTO control surveying. Extensive fieldwork campaigns in the winter of 2010 and summer of 2011 were carried out and ˜300 hours of static and ˜50 hours of kinematic network RTK data were collected from three different service providers. A set of metrics were defined to characterize the performance of network RTK: availability, time-to-first-fix, precision, accuracy, solution integrity and moving average filtering. The data were used to characterize the horizontal performance of network RTK services and the results along with a set of guidelines and specifications were provided (Saeidi et al., 2011; Bisnath et al., 2012). This thesis presents the horizontal network RTK performance evaluation, as well as the vertical and kinematic performance. The aforementioned metrics are used to evaluate the quality of network RTK in southern Ontario, and to compare to similar services available in other locations. The result have revealed expected ˜2-3 cm (95%) precision for the horizontal and vertical components; however, large horizontal and vertical biases were observed, which can be as high as 4 cm. The solution integrity has shown that typically, 3? solution uncertainties are larger than the actual errors, unless large biases exist. Moving average filtering has confirmed that due to large outliers and spikes in the solutions, 1 second observation periods are not sufficient to provide a precise solution; larger observation windows should be used, e.g., 5 minutes, to reduce the magnitude of maximum errors. The kinematic analysis has revealed issues with synchronization and timing between different data sets. Also, low solution availability while using the network RTK in kinematic mode is seen throughout the results. Overall, network RTK service performance in southern Ontario is slightly lower than the norm reported from similar services in other places.

The effect of Antarctic sea ice on the Southern Hemisphere atmosphere during the southern summer  

NASA Astrophysics Data System (ADS)

This study examines the influence of Antarctic sea ice distribution on the large scale circulation of the Southern Hemisphere using a fully coupled GCM where the sea ice submodel is replaced by a climatology of observed extremes in sea ice concentration. Three 150-year simulations were completed for maximum, minimum and average sea ice concentrations and the results for the austral summer (January-March) were compared using the surface temperatures forced by the sea ice distributions as a filter for creating the composite differences. The results indicate that in the austral summer the polar cell expands (contracts) under minimum (maximum) sea ice conditions with corresponding shifts in the midlatitude Ferrell cell. We suggest that this response occurs because sea ice lies in the margin between the polar and midlatitude cells. The polarity of the Southern Hemisphere Annular (SAM) mode is also influenced such that when sea ice is at a minimum (maximum) the polarity of the SAM tends to be negative (positive).

Even these early approach frames show wild dynamics in the roiling environment south of the white belt. Notice the small tumbling white cloud near the center.

As Voyager 1 approached Jupiter in 1979, it took images of the planet at regular intervals. This sequence is made from 17 images taken once every Jupiter rotation period (about 10 hours). These images were acquired in the Blue filter around Feb. 1, 1979. The spacecraft was about 37 million kilometers from Jupiter at that time.

Several datasets regarding the ocean in the Southern Hemisphere are combined into a coregistered format to analyze the use of the data in multidisciplinary research. The datasets are described detailing bathymetric climatological data on surface pigment concentration, eddy-kinetic-energy measurements, surface wind-stress magnitudes, sea-surface temperatures, surface densities, and nitrate concentrations. The data are combined in a common projection which facilitates the comparison of the fields, and the combined data yield insights regarding such phenomena as bottom topography, surface heat and moisture fluxes, and divergences in flow. The number of available datasets is shown to be good, and the data can be used to develop working hypotheses on the relationships between physical and biogeochemical processes.

NASA Technical Reports Server (NTRS)

Parameters of the UK 1.2 meter Schmidt telescope are described. Plates taken with this instrument are in two categories, those for systematic sky surveys and those taken at the request of research users. A collaborative project with the European Southern Observatory was undertaken to obtain a two-color survey of the sky south of -20 deg declination to complement the Palomar survey. A near infrared survey of the Galactic Plane and the Megallanic Clouds is being done. The area south of -20 deg and the zone between 0 deg and -15 deg are also being surveyed. Pending a decision on survey parameters, all available A quality prism plates are being retained to form a basis for systematic survey. Nearly half the plates taken on a service basis for the UK astronomical community are to fulfill nonsurvey requests. Plates taken for surveys which are not of A grade quality are also made available for research purposes.

Observations from an in progress program to study early type galaxies are presented. International Ultraviolet Explorer (IUE) spectra of the southern galaxies NGC 1326 and 1808 are presented and compared to IUE archival spectra of four galaxies of approximately similar morphological type. The targets were selected on the basis of their infrared astronomy satellite emission, peculiarities in their dust structure as revealed from charge coupled device frames and the presence of H I from 21 cm data. Preliminary results show large differences in stellar populations, and the presence of early spectral type stars are correlated with UV extinction and IR excess. Interpretation of the data is presented, discussing the correlations between extinction, gas content and stellar populations.

Interpretation of recent Southern Hemisphere climate change.  

PubMed

Climate variability in the high-latitude Southern Hemisphere (SH) is dominated by the SH annular mode, a large-scale pattern of variability characterized by fluctuations in the strength of the circumpolar vortex. We present evidence that recent trends in the SH tropospheric circulation can be interpreted as a bias toward the high-index polarity of this pattern, with stronger westerly flow encircling the polar cap. It is argued that the largest and most significant tropospheric trends can be traced to recent trends in the lower stratospheric polar vortex, which are due largely to photochemical ozone losses. During the summer-fall season, the trend toward stronger circumpolar flow has contributed substantially to the observed warming over the Antarctic Peninsula and Patagonia and to the cooling over eastern Antarctica and the Antarctic plateau.

Wastewater effluent dispersal in Southern California Bays  

NASA Astrophysics Data System (ADS)

The dispersal and dilution of urban wastewater effluents from offshore, subsurface outfalls is simulated with a comprehensive circulation model with downscaling in nested grid configurations for San Pedro and Santa Monica Bays in Southern California during Fall of 2006. The circulation is comprised of mean persistent currents, mesoscale and submesoscale eddies, and tides. Effluent volume inflow rates at Huntington Beach and Hyperion are specified, and both their present outfall locations and alternative nearshore diversion sites are assessed. The effluent tracer concentration fields are highly intermittent mainly due to eddy currents, and their probability distribution functions have long tails of high concentration. The dilution rate is controlled by submesoscale stirring and straining in tracer filaments. The dominant dispersal pattern is alongshore in both directions, approximately along isobaths, over distances of more than 10 km before dilution takes over. The current outfall locations mostly keep the effluent below the surface and away from the shore, as intended, but the nearshore diversions do not.

Late Holocene paleoecology of the Southern Plains  

NASA Astrophysics Data System (ADS)

Analyses of pollen and land snails from rocksheter sites in the Osage Hills of northeastern Oklahoma indicate that the period 2000-1000 yr B.P. was moister than today. During that time, colonies of the prairie vole Microtus ochrogaster were present in the Texas Panhandle. About 1000 yr B.P. the climate changed to dry conditions that have persisted to the present. Disjunct colonies of small mammals in Texas became extinct at the beginning of the dry episode, thereby establishing the composition of the modern fauna. The climatic model for the origin of the Panhandle Aspect (A.D. 1200-1500) is questioned on the grounds that the Southern Plains experienced a long period of dry climate commencing A.D. 950.

SAAMER transmits 10 times more power than regular meteor radars, and uses a newly developed transmitting array, which focuses power upward instead of the traditional single-antenna-all-sky configuration. The system is configured such that the transmitter array can also be utilized as a receiver. The new design greatly increases the sensitivity of the radar enabling the detection of large number of particles at low zenith angles. The more concentrated transmitted power enables additional meteor studies besides those typical of these systems based on the detection of specular reflections, such as routine detections of head echoes and non-specular trails, previously only possible with High Power and Large Aperture radars. In August 2010, SAAMER was upgraded to a system capable to determine meteoroid orbital parameters. This was achieved by adding two remote receiving stations approximately 10 km away from the main site in near perpendicular directions. The upgrade significantly expands the science that is achieved with this new radar enabling us to study the orbital properties of the interplanetary dust environment. Because of the unique geographical location, SAAMER allows for additional inter-hemispheric comparison with measurements from Canadian Meteor Orbit Radar, which is geographically conjugate. Initial surveys show, for example, that SAAMER observes a very strong contribution of the South Toroidal Sporadic meteor source, of which limited observational data is available. In addition, SAAMER offers similar unique capabilities for meteor showers and streams studies given the range of ecliptic latitudes that the system enables detailed study of showers at high southern latitudes (e.g July Phoenicids or Puppids complex). Finally, SAAMER is ideal for the deployment of complementary instrumentation in both, permanent and campaign, operational mode. Results from various radar meteor investigations as well as radar/optical observation campaign will be presented in this paper.

Extratropical Cyclone in the Southern Ocean  

NASA Technical Reports Server (NTRS)

These images from the Multi-angle Imaging SpectroRadiometer (MISR) portray an occluded extratropical cyclone situated in the Southern Ocean, about 650 kilometers south of the Eyre Peninsula, South Australia. The left-hand image, a true-color view from MISR's nadir (vertical-viewing) camera, shows clouds just south of the Yorke Peninsula and the Murray-Darling river basin in Australia. Retrieved cloud-tracked wind velocities are indicated by the superimposed arrows. The image on the right displays cloud-top heights. Areas where cloud heights could not be retrieved are shown in black. Both the wind vectors and the cloud heights were derived using data from multiple MISR cameras within automated computer processing algorithms. The stereoscopic algorithms used to generate these results are still being refined, and future versions of these products may show modest changes. Extratropical cyclones are the dominant weather system at midlatitudes, and the term is used generically for regional low-pressure systems in the mid- to high-latitudes. In the southern hemisphere, cyclonic rotation is clockwise. These storms obtain their energy from temperature differences between air masses on either side of warm and cold fronts, and their characteristic pattern is of warm and cold fronts radiating out from a migrating low pressure center which forms, deepens, and dissipates as the fronts fold and collapse on each other. The center of this cyclone has started to decay, with the band of cloud to the south most likely representing the main front that was originally connected with the cyclonic circulation. These views were acquired on October 11, 2001, and the large view represents an area of about 380 kilometers x 1900 kilometers. Image courtesy NASA/GSFC/LaRC/JPL, MISR Team.

Tectonic Rotations in the Southern Central Andes  

NASA Astrophysics Data System (ADS)

During the last ten years numerous paleomagnetic studies have reported large clockwise rotations (>25°) in Mesozoic and early Paleogene rocks along the forearc of northern Chile (Arriagada et al., 2003, doi:10.1029/2001JB001598; Arriagada et al., 2006, doi:10.1029/2005TC001923; Taylor et al., 2007, doi:10.1029/2005JB003950). Taylor et al (2007) have argued that these rotations occurred in response to rapid and highly oblique Nazca-South American plate convergence between 60-45 Ma, prior to later Incaic deformation mostly localized along the Domeyko fault system (DFS). However, the striking symmetry of the pattern of clockwise rotations in northern Chile and counterclockwise rotations in southern Peru (Roperch et al., 2006, doi:10.1029/2005TC001882) suggests that rotations likely occurred contemporaneously with the rotations in Peru and pre 20 Ma compressional deformation in the Bolivian Eastern Cordillera. Thus the rotations within the Chilean forearc appear to be not only the result of transpression associated to oblique convergence west of the DFS but also to deformation that should have occurred across the Puna region during the late Eocene - Oligocene. To test this hypothesis, we drilled 31 sites in late Paleozoic and Tertiary (pre Miocene) red beds in the southern Puna. Characteristic remanent magnetizations were determined after detailed thermal demagnetization. Preliminary results show a regional pattern of highly variable clockwise rotations. Measurements of anisotropy of magnetic susceptibility show that most sites record a well-defined magnetic lineation oriented either NS or NNE- SSW that we interpret as evidence for the record of Andean compression even at sites far away from major thrust faults. The deviation of the AMS lineation from a NS trend can be correlated with the tectonic rotation determined by the characteristic remanent magnetizations.

Northerners versus southerners: Italian anthropology and psychology faced with the "southern question".  

PubMed

Following the Unification of Italy (1861), when confronted with the underdevelopment problems of the south that had given rise to the so-called "southern question," some Italian anthropologists and psychologists began to study the populations of the south from the psycho-anthropological point of view. These scientists, at times subject to preconceived ideas toward the southerners, conveyed observations and descriptions of the southern character traits that, in general, were considered different, in a negative sense, with respect to those of the northern peoples. To explain such diversity in the "psychological" characteristics between the north and south of the country (presumed cause also of the south's backwardness), various hypotheses were advanced related to the kind of heredity theory adopted, which could be of, more or less, an "innatist" or "transformist" or "environmentalist" kind. The distinction proposed in this article between at least 2 different "hereditarian" theories formulated by the Italian scientists, and the confrontation of these theories with the hypotheses expressed by the "southernist" sociologists, contrary to the idea of "racial varieties" present in the Italian population, allows one to understand in what way and in what sense, at the threshold of the 20th century, there arose the ideology of "Nordicism" and the roots of racism were planted.

Upper Permian fluviolacustrine deposits of southern Africa and the late Permian climate southern Gondwana  

SciTech Connect

Upper Permian-age fluviolacustrine deposits are widespread throughout southern Africa. In the southern part of the subcontinent, where deposition took place in foreland basin settings, the sequences are thicker and fluvial-dominated whereas, lacustrine-dominated deposits accumulated in settings of low relief, broad warping and mild faulting at the northern end. The geographic extent and lateral correlatability of these deposits suggest the existence of concurrent, perhaps interconnected, giant lakes within major fluvial frameworks throughout the subcontinent, thousands of miles inland from the sea. This period of major lake development within fluvial depositional settings suggests climatic conditions that sustained a uniquely wet continental environment, deep in the heart of the Gondwanan supercontinent. Simulations based on various general circulation and energy balance climate models predict extreme seasonal temperatures and aridity for Gondwana at the palaeolatitudes of southern Africa during the Late Permian. On the other hand, distribution of climate-sensitive rocks, palynologic and palaeobotanic data and vertebrate fossils, coroborate the temperature climate documented by sedimentologic studies. The erroneous modeling results may have arisen from the fact that the models do not employ palaeogeographies that accommodate the existence of the vast lakes and rivers of Gondwana. The Late Permian palaeogeography of series of giant lakes within major fluvial frameworks would have had considerable influences on the regional climate. This suggests that it is imperative that numerical modeling studies incorporate accurate palaeogeographies, constructed based on available geological data, in order to recreate past climates with acceptable degree of accuracy.

Processes controlling Southern Ocean cloud-climate feedbacks (Invited)  

NASA Astrophysics Data System (ADS)

We use a fully coupled climate model (CESM) to identify processes controlling intriguingly diverse Southern Ocean cloud feedbacks in response to increased greenhouse gas forcing. Modeled Southern Ocean cloud-climate feedbacks range from the most positive (enhancing greenhouse warming at ~40 degrees South) to the most negative (damping greenhouse warming at ~60 degrees South) on the planet. As greenhouse gas concentrations increase, Antarctic sea ice loss, warming, and a poleward stormtrack shift/sub-tropical expansion all modify Southern Ocean clouds. Our analysis shows that Southern Ocean clouds are controlled both by thermodynamics (cloud changes for a given subsidence rate) and by dynamics (changes in subsidence rates). Hinting at the importance of thermodynamics, absorbed shortwave radiation over the Southern Ocean is substantially more affected by increased greenhouse gas forcing than by a poleward stormtrack shift in the absence of greenhouse forcing. While we find CESM a useful tool, CESM has substantial Southern Ocean biases (e.g., excessive Antarctic sea ice, excessive absorbed shortwave radiation). Thus, we also assess the impact that these biases have on the realism of CESM Southern Ocean cloud-climate greenhouse feedbacks.

Clean Air Slots Amid Dense Atmospheric Pollution in Southern Africa  

NASA Technical Reports Server (NTRS)

During the flights of the University of Washington's Convair-580 in the Southern African Regional Science Initiative (SAFARI 2000) in southern Africa, a phenomenon was observed that has not been reported previously. This was the occurrence of thin layers of remarkably clean air, sandwiched between heavily polluted air, which persisted for many hours during the day. Photographs are shown of these clean air slots (CAS), and particle concentrations and light scattering coefficients in and around such slot are presented. An explanation is proposed for the propensity of CAS to form in southern Africa during the dry season.

Olivine in the Southern Isidis Basin  

NASA Technical Reports Server (NTRS)

The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) took this observation of the transition region between Libya Montes and the Isidis Basin on Mars at 17:16 UTC (12:16 p.m. EST) on January 2, 2007, near 3.6 degrees north latitude, 84.1 degrees east longitude. The image was taken in 544 colors covering 0.36-3.92 micrometers, and shows features as small as 18 meters (60 feet) across. The image is about 11 kilometers (7 miles) wide at its narrowest point.

The Isidis Basin resulted from of a gigantic impact on the surface of Mars early in the planet's history. The southern rim, where this target is located, is a region of complex geology and part of the planetary dichotomy boundary that separates the older southern highlands from the lower, younger northern plains. The image on the left was constructed from three visible wavelengths (RGB: 0.71, 0.60, 0.53 microns) and is a close approximation of how the surface would appear to the human eye. The image on the right was constructed from three infrared wavelengths (RGB: 2.49, 1.52, 1.08 microns) chosen to highlight variations in the mineralogy of the area. Of interest is that features in this image not only differ in color, but also in texture and morphology. The gray areas absorb similarly at all wavelengths used in this image, but display absorptions at other wavelengths related to the iron- and magesium-rich mineral pyroxene. The reddest areas absorb strongly at the wavelengths used for green and blue, which is attributable to another iron- and magesium-rich mineral, olivine. The brownish areas show subdued mineral absorptions and could represent some type of mixture between the other two materials. The presence of the mineral olivine is particularly interesting because olivine easily weathers to other minerals; thus, its presence indicates either the lack of weathering in this region or relatively recent exposure.

CRISM's mission: Find the spectral fingerprints of aqueous and hydrothermal deposits and map the geology, composition and stratigraphy of surface features. The instrument will also watch the seasonal variations in Martian dust and ice aerosols, and water content in surface materials -- leading to new understanding of the climate.

The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) is one of six science instruments on NASA's Mars Reconnaissance Orbiter. Led by The Johns Hopkins University Applied Physics Laboratory, the CRISM team includes expertise from universities, government agencies and small businesses in the United States and abroad.

Volatile organic compound sources for Southern Finland  

NASA Astrophysics Data System (ADS)

Volatile organic compounds (VOCs) have several sources, both biogenic and anthropogenic. Emissions of biogenic VOCs in a global scale are estimated to be an order of magnitude higher than anthropogenic ones. However, in densely populated areas and during winter time the anthropogenic VOC emissions dominate over the biogenic ones. The aim of this study was to clarify potential local sources and source areas of VOCs in different seasons. Diurnal behaviour in winter and spring were also compared at two different sites in Finland: SMEAR II and III (Station for Measuring Ecosystem - Atmosphere Relations). SMEAR II is a rural site located in Hyytiälä in Southern Finland 220 km North-West from Helsinki whereas SMEAR III is background urban site located 5 km from the downtown of Helsinki. The volume mixing ratios of VOCs were measured with a proton-transfer-reaction mass spectrometer (PTR-MS, Ionicon Analytik GmbH, Austria) during years 2006-2011. Other trace gases such as CO, NOXand SO2 were also measured in both sites and used for source analysis. Source areas for long term VOC measurements were investigated with trajectory analysis and sources for local and regional concentrations were determined by Unmix multivariate receptor model. Forest fires affect air quality and the biggest smoke plumes can be seen in satellite images and even hinder visibility in the plume areas. They provide temporally and spatially well-defined sources that can be used to verify source area estimates. During the measurement periods two different forest fire episodes with several hotspots, happened in Russia. Forest fires which showed up in these measurements were in 2006 near the border of Finland in Vyborg area and 2010 in Moscow area. Forest fire episodes were clearly observed in trajectory analysis for benzene, toluene and methanol and also CO and NOX. In addition to event sources continuous source areas were determined. Anthropogenic local sources seemed to be dominant during winter in both sites. However during spring biogenic influence increased. In addition to source analysis this behaviour was visible in enhanced diurnal cycles of VOCs (Patokoski et al., 2014, in press). We will present important sources and source areas for Southern Finland's concentrations.

Lower Mississippian trilobites from southern New Mexico  

USGS Publications Warehouse

Twenty-three species of trilobites are recognized in the lower Mississippian Caballero and Lake Valley Formations of southern New Mexico. Species exhibit a segregation into shelf and off-shelf faunas, and can be subdivided into three distinct stratigraphic faunas. Species found in the Caballero Formation are similar to those found in the Chouteau Formation of Missouri. A second fauna, comprising species found in the Alamogordo, Nunn, and Tierra Blanca Members of the Lake Valley Formation, is correlated with the Fern Glen and Burlington Formations of Missouri. The third fauna found in the Arcente and Dona Aha Members of the Lake Valley Formation is correlated with the Warsaw and Salem Formations of the United States midcontinent region. Named species from the Kinderhookian Caballero Formation include: Dixiphopyge armata (Vogdes, 1891), Comptonaspis swallowi (Shumard, 1855), Brachymetopus indianwellsensis new species, Ameropiltonia perplexa new species, Griffithidella caballeroensis new species, and Kollarcephalus granatai new genus and new species. Named species from the Lake Valley Formation include: Pudoproetus fernglenensis (Weller, 1909), Breviphillipsia semiteretis Hessler, 1963, Griffithidella doris (Hall 1860), Phillibole planucauda (Brezinski, 1998), Piltonia carlakertisae new species, Australosutura llanoensis Brezinski, 1998, Thigriffides triangulatus new species, Thigriffides? alamogordoensis new species, Namuropyge newmexicoensis new species, Nunnaspis stitti new genus and new species, Hesslerides arcentensis new genus and new species, as well as an unnamed species of Proetides Hessler, 1962, Namuropyge Brezinski, 1988, and Thigriffides Hessler, 1965.

Observations of southern emission-line stars  

NASA Technical Reports Server (NTRS)

A catalog of 1929 stars showing H-alpha emission on photographic plates is presented which covers the entire southern sky south of declination -25 deg to a red limiting magnitude of about 11.0. The catalog provides previous designations of known emission-line stars equatorial (1900) and galactic coordinates, visual and photographic magnitudes, H-alpha emission parameters, spectral types, and notes on unusual spectral features. The objects listed include 16 M stars, 25 S stars, 37 carbon stars, 20 symbiotic stars, 40 confirmed or suspected T Tauri stars, 16 novae, 14 planetary nebulae, 11 P Cygni stars, 9 Bep stars, 87 confirmed or suspected Wolf-Rayet stars, and 26 'peculiar' stars. Two new T associations are discovered, one in Lupus and one in Chamaeleon. Objects with variations in continuum or H-alpha intensity are noted, and the distribution by spectral type is analyzed. It is found that the sky distribution of these emission-line stars shows significant concentrations in the region of the small Sagittarius cloud and in the Carina region.

Helminths of the ocelot from southern Texas.  

PubMed

In the USA, the ocelot (Leopardus pardalis) is a highly endangered felid found only in a few remaining vestiges of native thornshrub brushland in the Lower Rio Grande Valley (LRGV) of extreme southern Texas. From 1987-1998, carcasses of 15 adult ocelots that died of vehicular accidents or natural causes were examined for helminths. All cats had 1-8 (mean = 3) helminth species. All were infected with 1-101 (mean +/- SE = 32 +/- 7) Toxascaris leonina. Other helminths from these ocelots were Alaria marcianae, Brachylaima sp., Mesocestoides lineatus, Taenia rileyi, Oncicola canis, Dirofilaria immitis, Physaloptera rara, Ancylostoma tubaeformae, Cylicospirura chevreuxi, Vogeloides felis, and Metathelazia californica. Additionally, two cats had scarring of the aorta with lesions typical of those caused by Spriocerca lupi, although larval nematodes were not seen. A clinal variation in size of nearly three orders of magnitude was noted in the diplostomatid trematodes in the small intestine of one adult male ocelot. Despite the differences in size, all specimens appeared morphologically identical and were regarded as A. marcianae. Helminth prevalences and abundances, including those of potentially pathogenic species like D. immitis, were low. Although a single heartworm infection may have contributed to the death of one ocelot, helminth infections in general seemed to be of no great consequence to this endangered ocelot population. The helminth fauna of ocelots in the LRGV is reflective of that from wild felids in general; all have been reported previously from the bobcat (Lynx rufus) and mountain lion (Puma concolor) elsewhere in Texas.

NH3 observations of southern cold cores  

NASA Astrophysics Data System (ADS)

We propose an NH3 spectral line study of southern massive star formation sources that have been mapped in millimetre continuum emission using the SIMBA bolometer on the SEST. Following a multiwavelength investigation into these cores, using followup and existing submillimetre continuum observations as well as archival infrared data, we have drawn spectral energy distribution (SED) diagrams for the cores. SED profiling reveals source specific parameters such as their temperature and luminosity. Analysis of our SED fits indicates a differentiation in temperature for cores devoid of methanol maser sources and/or UC HII regions compared to those associated with these objects. This has led us to propose that this temperature differentiation is indicative of an evolutionary sequence for the cores in our sample. We now need an independent determination of the temperature of the cores in order to test the robustness of our SED fits and hypotheses drawn from these fits. A systematic determination of the temperature of all the cores in the sample will allow determination of the temperature and subsequent analysis of cores without enough data to SED profile. Ammonia is an excellent molecular cloud thermometer and is perfectly suited to this work.

Bathymetry of southern Mauna Loa Volcano, Hawaii  

USGS Publications Warehouse

Manua Loa, the largest volcano on Earth, lies largely beneath the sea, and until recently only generalized bathymetry of this giant volcano was available. However, within the last two decades, the development of multibeam sonar and the improvement of satellite systems (Global Positioning System) have increased the availability of precise bathymetric mapping. This map combines topography of the subaerial southern part of the volcano with modern multibeam bathymetric data from the south submarine flank. The map includes the summit caldera of Mauna Loa Volcano and the entire length of the 100-km-long southwest rift zone that is marked by a much more pronounced ridge below sea level than above. The 60-km-long segment of the rift zone abruptly changes trend from southwest to south 30 km from the summit. It extends from this bend out to sea at the south cape of the island (Kalae) to 4 to 4.5 km depth where it impinges on the elongate west ridge of Apuupuu Seamount. The west submarine flank of the rift-zone ridge connects with the Kahuku fault on land and both are part of the ampitheater head of a major submarine landslide (Lipman and others, 1990; Moore and Clague, 1992). Two pre-Hawaiian volcanic seamounts in the map area, Apuupuu and Dana Seamounts, are apparently Cretaceous in age and are somewhat younger than the Cretaceous oceanic crust on which they are built.

Southern Regional Center for Lightweight Innovative Design  

SciTech Connect

The Southern Regional Center for Lightweight Innovative Design (SRCLID) has developed an experimentally validated cradle-to-grave modeling and simulation effort to optimize automotive components in order to decrease weight and cost, yet increase performance and safety in crash scenarios. In summary, the three major objectives of this project are accomplished: To develop experimentally validated cradle-to-grave modeling and simulation tools to optimize automotive and truck components for lightweighting materials (aluminum, steel, and Mg alloys and polymer-based composites) with consideration of uncertainty to decrease weight and cost, yet increase the performance and safety in impact scenarios; To develop multiscale computational models that quantify microstructure-property relations by evaluating various length scales, from the atomic through component levels, for each step of the manufacturing process for vehicles; and To develop an integrated K-12 educational program to educate students on lightweighting designs and impact scenarios. In this final report, we divided the content into two parts: the first part contains the development of building blocks for the project, including materials and process models, process-structure-property (PSP) relationship, and experimental validation capabilities; the second part presents the demonstration task for Mg front-end work associated with USAMP projects.

Uranium mineralization in southern Victoria Land, Antarctica  

SciTech Connect

For the past 10 antarctic field seasons, an airborne gamma-ray spectrometric survey has been conducted over widely separated parts of the continent. Localized accumulations of both primary and secondary uranium minerals have been discovered at several localities scattered along the Transantarctic Mountains from the Scott Glacier to northern Victoria Land. A number of highly significant radiation anomalies have been discovered in the area between the Koettlitz Glacier and the Pyramid Trough. The occurrences consist of pegmatite vein complexes which contain an association of primary uranium and thorium minerals. Of still greater significance is the fact that abundant secondary uranium minerals were found in association with the primary deposits, and they indicate clearly that uranium is geochemically mobile under the conditions imposed by the arid polar climate that now exists in southern Victoria Land. Preliminary results of a uranium analysis performed by neutron activation indicate a concentration of 0.12% uranium in a composite sample from the two veins. Even higher levels of thorium are present. The nature of the primary uranium mineralization is currently under investigation. Preliminary results are discussed.

Beta-Thalassaemia types in southern Sardinia.  

PubMed Central

In this study the prevalence of the different beta-thalassaemia types in southern Sardinia was investigated by cellulose acetate and agar gel electrophoresis or globin chain synthesis analysis on column chromatography or both in (1) all the patients (347) presenting with thalassaemia major or intermedia at our haematology service from 1976 to 1979, and (2) a group of 82 patients with transfusion-dependent thalassaemia major randomly chosen from 236 under our care. Apart from six subjects with delta(beta)0/beta+-thalassaemia genotype and eight with beta0/beta+ or less probably beta+/beta/-thalassaemia, all thalassaemia major and intermedia patients studied were beta0-thalassaemia homozygotes. Globin chain synthesis on peripheral blood cells from these patients, performed at different intervals from blood transfusion, showed no incorporation of radioactive leucine into beta-globin peak, the same as before the transfusion. No correlation between kappa/gamma ratios and clinical severity or hypersplenism was found. Globin chain synthesis analysis carried out at birth in three infants later found to have homozygous beta0-thalassaemia demonstrated imbalanced or borderline kappa/gamma ratios. Images PMID:7241542

In the case of Southern Vietnam, is of high concern dioxin contamination in the areas affected by past-use chemical defoliants. Our study related to the zone considered as a "hot spot"--Bien Hoa Airbase and surrounding areas (Bien Hung Lake). Although the war ended over 30 years ago, the adverse effects on this territory still continue. Soil and sediment were selected for our research as they act as a sink for PCDD/Fs. The samples were taken and analyzed in CECOTOX laboratory following certified procedures. The total amounts of PCDD/Fs (2,3,7,8 related congeners) in the samples were converted into WHO-TEQ and compared with standard values proposed by Canadian environmental quality guidelines. The obtained data shows a relatively high risk (up to 20.4 times higher than (probable effect level) PEL value for sediment and 46 times higher than standard value for soil). The research is continuing on the assessment of dioxin transport in food chain. Moreover, considering the obtained data a complete solution should be found urgently to solve the problem of dioxin contamination in the studied areas. PMID:17222446

Antarctic ice sheet fertilises the Southern Ocean  

NASA Astrophysics Data System (ADS)

Southern Ocean (SO) marine primary productivity (PP) is strongly influenced by the availability of iron in surface waters, which is thought to exert a significant control upon atmospheric CO2 concentrations on glacial/interglacial timescales. The zone bordering the Antarctic Ice Sheet exhibits high PP and seasonal plankton blooms in response to light and variations in iron availability. The sources of iron stimulating elevated SO PP are in debate. Established contributors include dust, coastal sediments/upwelling, icebergs and sea ice. Subglacial meltwater exported at the ice margin is a more recent suggestion, arising from intense iron cycling beneath the ice sheet. Icebergs and subglacial meltwater may supply a large amount of bioavailable iron to the SO, estimated in this study at 0.07-0.2 Tg yr-1. Here we apply the MIT global ocean model (Follows et al., 2007) to determine the potential impact of this level of iron export from the ice sheet upon SO PP. The export of iron from the ice sheet raises modelled SO PP by up to 40%, and provides one plausible explanation for seasonally very high in situ measurements of PP in the near-coastal zone. The impact on SO PP is greatest in coastal regions, which are also areas of high measured marine PP. These results suggest that the export of Antarctic runoff and icebergs may have an important impact on SO PP and should be included in future biogeochemical modelling.

ICESat Observations of Southern Alaska Glaciers  

NASA Technical Reports Server (NTRS)

In late February and March, 2003, the Ice, Cloud, and land Elevation Satellite (ICESat) measured ice and land elevations along profiles across southern Alaska. During this initial data acquisition stage ICESat observations were made on 8-day repeat tracks to enable calibration and validation of the ICESat data products. Each profile consists of a series of single point values derived from centroid elevations of an $\\approx$70 m diameter laser footprint. The points are s4pakated by $\\approx$172 m along track. Data siets of 8-day observations (an ascending and descending ground track) crossed the Bering and Malaspina Glacier. Following its 1993--1995 surge; the Bering Glacier has undergone major terminus retreat as well as ike thinning in the abtation zone. During the later part of the 20th century, parts of the Malaspina thinned by about 1 m/yr. The multiple observation profiles across the Bering and Malaspina piedmont lobes obtained in February/March are being geolocated on Landsat images and the elevation profiles will be used for a number o scientific objectives. Based on our simulations of ICESat performance over the varied ice surface of the Jakobshavn Glacier of GReenland, 2003, we expect to measure annual, and possibly seasonal, ice elevation changes on the large Alaskan glaciers. Using elevation data obtained from a second laser, we plan to estimate ice elevation changes on the Bering Glacier between March and October 2003.

A model El Nino-Southern Oscillation  

NASA Technical Reports Server (NTRS)

A coupled atmosphere-ocean model is developed and used to study the ENSO (El Nino/Southern Oscillation) phenomenon. With no anomalous external forcing, the coupled model reproduces certain key features of the observed phenomenon, including the recurrence of warm events at irregular intervals with a preference for three to four years. It is shown that the mean sea surface temperature, wind and ocean current fields determine the characteristic spatial structure of ENSO anomalies. The tendency for phase-locking of anomalies is explained in terms of a variation in coupling strength associated with the annual cycle in the mean fields. Sensitivity studies reveal that both the amplitude and the time scale of the oscillation are sensitive to several parameters that affect the strength of the atmosphere-ocean coupling. Stronger coupling implies larger oscillations with a longer timescale. A critical element of the model oscillation is the variability in the equatorial heat content of the upper ocean. Equatorial heat content increases prior to warm events and decreases sharply during the events. A theory for this variability and the associated transitions between non-El Nino and El Nino states is presented. Implications of the model results for the prediction of El Nino events are discussed.

Magnetotelluric Data, Southern San Luis Valley, Colorado  

USGS Publications Warehouse

Introduction The population of the San Luis Valley region is growing rapidly. The shallow unconfined and the deeper confined Santa Fe Group aquifer in the San Luis Basin is the main sources of municipal water for the region. Water shortfalls could have serious consequences. Future growth and land management in the region depend on accurate assessment and protection of the region's ground-water resources. An important issue in managing the ground-water resources is a better understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits that fill the Rio Grande rift, which contain the principal ground-water aquifers. The U.S. Geological Survey (USGS) is conducting a series of multidisciplinary studies of the San Luis Basin located in southern Colorado. Detailed geologic mapping, high-resolution airborne magnetic surveys, gravity surveys, an electromagnetic survey, called magnetotellurics (MT), and hydrologic and lithologic data are being used to better understand the aquifer systems. The primary goal of the MT survey is to map changes in electrical resistivity with depth that are related to differences in rock type. These various rock types help control the properties of aquifers in the region. This report does not include any interpretation of the data. Its purpose is to release the MT data acquired at the 22 stations shown in figure 1.

Sediment Dynamics and Southern Steelhead Habitat (Oncorhynchus mykiss) in the Matilija Creek Watershed, Southern California  

NASA Astrophysics Data System (ADS)

Matilija Creek, one of two principal forks of the Ventura River, drains 142 km2 in the Transverse Ranges of southern California. Thanks to rapid tectonic uplift and weak clastic rocks, sediment yields exceed 1200 m3/km2 annually. Matilija Dam was built in 1947 with an initial capacity of 8 million m3 and is now nearly full of sediment. The dam is structurally unsafe, blocks anadromous fish migration, and is being considered for removal. The Ventura River has one of the southernmost runs of steelhead trout (Oncorhynchus mykiss), with an average of approximately 2,500 annually migrating up Matilija Creek before the dam was built. The high sediment yields and highly variable flow regime have raised questions about the interactions among high flows, sediment transfer from lower order tributaries to the third order channels used by the fish, and fish life history. Previous studies in Southern California have documented sediment yields (especially following debris flows and fires, and mostly in the San Gabriel Mountains), but the interaction of geomorphic processes and aquatic habitat in this highly episodic environment is not well understood. We used a combination of mapping and survey techniques, sediment traps, grain size analysis, lithologic analysis and scour rods to study intra-annual geomorphic processes and sediment dynamics affecting Southern Steelhead habitat in the Matilija Creek area in 16 study pools over the 2002 and 2003 flow seasons (dry and "normal", respectively) and found little sediment was deposited or scoured from pools. However, other processes not previously recognized significantly affected the steelhead habitat in the study pools including tufa cementation (carbonate deposition) and alder root growth in spawning gravels, as well as seasonal desiccation of some reaches. Removal of Matilija Dam will reopen suitable habitat to steelhead trout, but managers should recognize that habitat quality is likely to vary considerably from year-to-year, especially in response to episodic events.

Parasites and vector-borne pathogens of southern plains woodrats (Neotoma micropus) from southern Texas  

PubMed Central

From 2008–2010, southern plains woodrats (Neotoma micropus) from southern Texas, were examined for parasites and selected pathogens. Eight helminth species were recovered from 97 woodrats including, Trichuris neotomae from 78 (prevalence=80%), Ascarops sp. from 42 (43%), Nematodirus neotoma from 31 (32%), Raillietina sp. from nine (9%), Taenia taeniaeformis larvae from eight (8%), and an unidentified spiurid, a Scaphiostomum sp. and a Zonorchis sp. each from a single woodrat. Besnotia neotomofelis was detected in three (3%) woodrats and microfilaria were detected in seven (7%). PCR testing of blood samples from 104 woodrats detected a novel Babesia sp. in one (1%) and Hepatozoon sp. in 17 (16%) woodrats. Partial 18S rRNA gene sequence of the Babesia was 94% similar to B. conradae. Histologic examination of tissues detected intestinal coccidia in 7 of 104 (7%), Sarcocystis neotomafelis in 26 (25%), Hepatozoon sp. in 21 (20%), and Dunnifilaria meningica in four (4%) woodrats. Three woodrats (5%) were seropositive for Toxoplasma gondii. Ectoparasites recovered included fleas (Orchopeas sexdentatus and O. neotomae), ticks (Ixodes woodi and Ornithodoros turicata), mites (Trombicula sp. and Ornithonyssus (Bdellonyssus) bacoti) and bot flies (Cuterebra sp.). The only difference in prevalence related to gender was for N. neotoma (males > females, p=0.029). Prevalence of T. neotomae and all intestinal parasites combined was significantly higher in adults compared with juveniles (p=0.0068 and p=0.0004), respectively. Lesions or clinical signs were associated with Cuterebra, T. gondii, and B. neotomofelis. Collectively, these data indicate that woodrats from southern Texas harbor several parasites of veterinary and/or medical importance. PMID:22108764

Geomagnetic Field Response at Southern and Northern Hemisphere Babita Chandel, Shailendra Saini, Sneha Yadav,S.K.Vijay and A.K.Gwal Space Science Laboratory, Department of Physics, Barkatullah University, Bhopal-462026, India ABSTRACT: This paper represents the geomagnetic field response at Southern Hemisphere (MAITRI) and Northern Hemisphere (TROMSO). The Indian Antarctic Station MAITRI is located at geomagnetic Long. (66.030, 53.210) where as TROMSO is at geomagnetic Long. (66.030, 53.210). We studied the behaviour of geomagnetic field with respect to geomagnetic storms at both the stations TROMSO and MAITRI. It was observed that at Southern Hemisphere there is more variation in winter as compared to the summer season, where as in Northern Hemisphere the variations are more in summer as compared to winter. As in the Northern hemisphere the magnetospheric plasma is strongly turbulized in summer and in Southern hemisphere the magentospheric plasma is strongly turbulized in winter.

The South Pacific Convergence Zone and Southern Hemisphere Teleconnections  

NASA Astrophysics Data System (ADS)

The South Pacific Convergence Zone (SPCZ) delineates the main region of quasi-persistent convection in the tropical southwest Pacific. Interannual variability in its location has a significant impact on precipitation and to a lesser extent on temperature variability across many southwest Pacific Island states. SPCZ variability is significantly linked to variations in the El Niño-Southern Oscillation (ENSO) cycle, and to longer-scale variability in the Pacific characterised by the Interdecadal Pacific Oscillation (IPO, also known as the Pacific Decadal Oscillation). There also appear to be links between the SPCZ and higher latitude Southern Hemisphere circulation variability and the Southern Annular Mode. This presentation will review the nature of ENSO/IPO relationships with the SPCZ, and will discuss mechanisms for teleconnections with the SAM and the extratropical Southern Hemisphere circulation.

European Population Substructure: Clustering of Northern and Southern Populations  

PubMed Central

Using a genome-wide single nucleotide polymorphism (SNP) panel, we observed population structure in a diverse group of Europeans and European Americans. Under a variety of conditions and tests, there is a consistent and reproducible distinction between “northern” and “southern” European population groups: most individual participants with southern European ancestry (Italian, Spanish, Portuguese, and Greek) have >85% membership in the “southern” population; and most northern, western, eastern, and central Europeans have >90% in the “northern” population group. Ashkenazi Jewish as well as Sephardic Jewish origin also showed >85% membership in the “southern” population, consistent with a later Mediterranean origin of these ethnic groups. Based on this work, we have developed a core set of informative SNP markers that can control for this partition in European population structure in a variety of clinical and genetic studies.

The Southern Cone: A critical element in North American geology  

SciTech Connect

The Pacific and Atlantic-Gulf of Mexico continental margins converge towards southern Mexico, delimiting the Southern Cone of North American. The margins are controlled by late Precambrian to early Paleozoic rift systems. The Neoproterozoic rifts along the Pacific margin truncate the 1.3--1.0 Ga Grenville-Llano front and still older structural boundaries within the craton, such as the Snowbird line. The Atlantic margin originated by separation from another continent within the Grenville orogen near the time of the Precambrian-Cambrian boundary. The Gulf of Mexico margin was initiated with rifting at that time, but appears to truncate the Ordovician Taconian orogen in Georgia. The continental margins of the Southern Cone may prove critical in understanding the origin of North America as a discrete continent. A possible continuation of the Grenville-Llano front has now been identified along the Pacific margin of the East Antarctic craton; the opposite side of the Grenville orogen may be present in South America and East Antarctic; a southern continuation of the Taconic Appalachians may have been identified in southern South American and Antarctica (L. Dalla Salda et al., Geology, 1992 a;b: I. Dalziel, Geology, 1991, and GSA Today, 1992; P. Hoffman, Science, 1991; E. Moores, Geology, 1991). Thus the geology of the Southern Cone of North America provides opportunities for critical testing of these globally important hypotheses, notably through geochronometry, isotope geochemistry, stratigraphy, and paleobiogeography. Conversely, East Antarctica, southern Africa, and the proto-Andean margin of South America may offer exciting opportunities to further understanding of pre-Pangea geology across southern North America.

Synchronicity of historical dry spells in the Southern Hemisphere  

NASA Astrophysics Data System (ADS)

A shift in climate occurred during the mid-1970s that affected the hydroclimate of the Southern Hemisphere resulting in drying trends across continental regions including Australia, New Zealand and southern and western Africa. There is also anecdotal evidence of other periods of climatic synchronicity in the Southern Hemisphere (e.g. the 1920s and 1940s), indicating that the mid 1970s event may not be anomalous. This paper identifies periods within the last ~120 yr using statistical analysis where dry spells (in terms of annual to multi-decadal rainfall deficiencies) have coincided across the continental Southern Hemisphere in order to characterize temporal consistency. It is shown that synchronicity of dry spells is (a) most likely common over the last 120 yr and (b) associated with changes in the large-scale climate modes of the Pacific, Indian and Southern Oceans. Importantly, the findings presented in this paper have marked implications for drought management and drought forecasting studies in the Southern Hemisphere.

OVERVIEW OF NATURAL OIL SEEPAGE IN THE SANTA BARBARA CHANNEL AND SOUTHERN SANTA MARIA BASIN, SOUTHERN CALIFORNIA  

Microsoft Academic Search

A five year study of tars and oils in southern California waters and beaches is underway as part of a joint U.S. Geological Survey-Minerals Management Service (USGS\\/MMS) program to identify natural and anthropogenic sources. Natural sources for these petroleum hydrocarbons include ubiquitous onshore and offshore shallow oil seeps, especially prominent along the southern California coast. Anthropogenic sources include accidental oil

Characteristics of Southern California coastal aquifer systems  

USGS Publications Warehouse

Most groundwater produced within coastal Southern California occurs within three main types of siliciclastic basins: (1) deep (>600 m), elongate basins of the Transverse Ranges Physiographic Province, where basin axes and related fluvial systems strike parallel to tectonic structure, (2) deep (>6000 m), broad basins of the Los Angeles and Orange County coastal plains in the northern part of the Peninsular Ranges Physiographic Province, where fluvial systems cut across tectonic structure at high angles, and (3) shallow (75-350 m), relatively narrow fluvial valleys of the generally mountainous southern part of the Peninsular Ranges Physiographic Province in San Diego County. Groundwater pumped for agricultural, industrial, municipal, and private use from coastal aquifers within these basins increased with population growth since the mid-1850s. Despite a significant influx of imported water into the region in recent times, groundwater, although reduced as a component of total consumption, still constitutes a significant component of water supply. Historically, overdraft from the aquifers has caused land surface subsidence, flow between water basins with related migration of groundwater contaminants, as well as seawater intrusion into many shallow coastal aquifers. Although these effects have impacted water quality, most basins, particularly those with deeper aquifer systems, meet or exceed state and national primary and secondary drinking water standards. Municipalities, academicians, and local water and governmental agencies have studied the stratigraphy of these basins intensely since the early 1900s with the goals of understanding and better managing the important groundwater resource. Lack of a coordinated effort, due in part to jurisdictional issues, combined with the application of lithostratigraphic correlation techniques (based primarily on well cuttings coupled with limited borehole geophysics) have produced an often confusing, and occasionally conflicting, litany of names for the various formations, lithofacies, and aquifer systems identified within these basins. Despite these nomenclatural problems, available data show that most basins contain similar sequences of deposits and share similar geologic histories dominated by glacio-eustatic sea-level fluctuations, and overprinted by syndepositional and postdepositional tectonic deformation. Impermeable, indurated mid-Tertiary units typically form the base of each siliciclastic groundwater basin. These units are overlain by stacked sequences of Pliocene to Holocene interbedded marine, paralic, fluvial, and alluvial sediment (weakly indurated, folded, and fractured) that commonly contain the historically named "80-foot sand," "200-foot sand," and "400-foot gravel" in the upper part of the section. An unconformity, cut during the latest Pleistocene lowstand (??18O stage 2; ca. 18 ka), forms a major sequence boundary that separates these units from the overlying Holocene fluvial sands and gravels. Unconfined aquifers occur in amalgamated coarse facies near the bounding mountains (forebay area). These units are inferred to become lithologically more complex toward the center of the basins and coast line, where interbedded permeable and low-permeability alluvial, fluvial, paralic, and marine facies contain confined aquifers (pressure area). Coastal bounding faults limit intrabasin and/or interbasin flow in parts of many basins. ?? 2009 Geological Society of America.

Cross folding in southern Bighorn basin  

SciTech Connect

Analysis of Landsat Thematic Mapper imagery coupled with surface structural investigations of well-exposed folds in the southern Bighorn basin have revealed two northwest-trending folds that have been refolded. The eastern boundary of the Owl Creek Mountains is characterized by a well-defined alignment of folds that extend north-northwest from the Owl Creek thrust front. Bridger monocline, Wildhorse Butte anticline, and Red Hole anticline lie along this trend. Initial Laramide folding, probably during latest Cretaceous time, resulted in a single, continuous, north-northwest-trending anticline with a southwestward vergence. This anticline was progressively unfolded from south to north as the Owl Creek Range was thrust southward over the Wind River basin in earliest Eocene time; scissors-like vertical motion along this flexure rotated the axial surface of the early formed Bridger anticline, resulting in a monocline with a reversed vergence (northeastward). Formation of the Thermopolis/East Warm Springs anticline parallel to the north flank of the range accompanied thrusting and effectively refolded the northern end of the Wildhorse Butte anticline along an east-west axis. Faulting of the oversteepened south limb of the Red Hole cross fold was contemporaneous with folding. Cross-cutting fold axes in this area and the Mud Creek area to the west are best explained by a counterclockwise change in stress direction during the latest phase of the Laramide orogeny. Vertical movement along the eastern side of the Owl Creek Range results from differential motion in the hanging wall of the crystalline thrust sheet.
