    The Baratal limestone in the Gorny Altai Mountains, southern Siberia, occurs as large allochthonous blocks within a Cambrian accretionary complex that developed around the Siberia craton. Before the final accretion to Siberia in the Cambrian, the terrigenous clastic-free Baratal limestone was deposited directly upon a basaltic basement with a geochemical signature identical to that of modern oceanic plateau. The Baratal

    New phosphatic microfossils were recently discovered in an Ediacaran–Cambrian mid-oceanic paleo-atoll limestone in the southern Gorny Altai Mountains in southern Siberia. Microfossils with calcium phosphate shells are abundant in the limestone that occurs as an exotic block within a Cambrian accretionary complex in the Kurai area. SEM observations confirm that the calcium phosphatic shells are ellipsoidal and equal-sized, about 200–300 ?m

    Dzhangyskol is a small lake of glacial origin in the central part of the Altai Mountains in southern Siberia. Pollen stratigraphies and chronologies of two cores record the vegetational development of the area from the Late Glacial treeless landscape to the forest and steppe of today. The modern lake is a remnant of a much larger ice-dammed lake, which was

    The Chuya complex consists of more then 400 early Mesozoic lamprophyre dikes that occur in the vast territory in the structures of the Gorny and Mongolian Altay. Based on the irregular distribution of the dikes, various researchers have distinguished from 3 to 6 separate dike swarms or areas. Each of them is spatially connected with a specific simultaneous ore deposit. For example, in the Aktash area, there are the Aktash, Chagan-Uzun and other Sb-Hg deposits, in the territory of the South-Chuya area there are the Kalguta Mo-W and Chagan-Burgasy Ag-Pb deposits and within the Yustyd area there are the Askhatin-Gol Ni-Co-As deposit, Asgat, Ozernoe and Tolbonour Ag-Sb deposits. But the genetic link between the magmatic rocks and close in time and space ore deposits has not yet been proven. In this work samples of lamprophyre dikes from the largest areas (Yustyd and South Chuya) were studied. The dikes are extraordinarily similar in mineralogical and chemical aspects. The greatest differences are in the isotopic characteristics of the rocks. Lamprophyres and syenites of the South-Chuya area have negative eNd (~-4) and an elevated 87Sr/86Sr (>0.711) ratio whereas lamprophyres of the Yustyd area are close to BSE (eNd~0, 87Sr/86Sr=0.705-0.707)/ Using data on the composition of rock-forming minerals, study of chemical characteristics and composition of lamprophyre fluid inclusions, we propose different sources with similar geochemical characteristics and varying degrees of metasomatic mantle material provoked different isotopic composition. The resulting liquid rich in carbonates and composite fluids in conjunction with low degrees of melting generates approximately petrochemical and mineralogical similar compositions newly formed rocks.

    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.

    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.

    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.

    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

    Using the data on mitochondrial DNA (mtDNA) polymorphism, genetic structures of the four Turkic-speaking ethnic groups of Altai-Sayan highlands, Southern Altaians (Altai-Kizhi), Khakassians, Shorians, and Sojots, were described. Mitochondrial gene pools of the populations examined were characterized by different ratios between Mongoloid (M*, C, D, E, G, A, B, and F) and Caucasoid (H, U, T, J, and K) mtDNA lineages. All the populations studied had a strongly pronounced Mongoloid component, the frequency of which was 88.2% in Sojots, 75.9% in Khakassians, 67.4% in Altaians, and 64.3% in Shorians. Maximum frequency of the Caucasoid component (35.7%) was observed in Shorians. Phylogenetic and statistical analyses of the mtDNA group frequency distribution patterns in the gene pools of the ethnic populations of Altai-Sayan highlands and the adjacent territories showed that the populations of the region fell into three groups. The first group included Khakassians, Tuvinians and Altaians, the second group consisted of Sojots, Buryats, and Mongols, while the third group was composed of Uigurs, Kazakhs, and Kyrgyzes. The isolated position of Shorians among the populations examined can be explained by their different anthropological composition and their presumptive relatedness to Finno-Ugric populations of Siberia.

    Quantitative reconstruction of the Holocene vegetation and climate dynamics in the semiarid Mongolian Altai based on the palynological investigation of two sediment cores recovered from Hoton-Nur Lake (48°37'18''N, 88°20'45''E, 2083 m) in 1980 and 2004 (Tarasov et al., 2000, Rudaya et al., in press), suggests that boreal woodland replaced the primarily open landscape of northwestern Mongolia at about 10 kyr BP in response to a increase in precipitation from 200-250 mm/yr to 450-550 mm/yr. A decline of the forest vegetation and a return to a predominance of open vegetation types occurred after 5 kyr BP when precipitation sums dropped dawn to 250-300 mm/yr. This pattern resembles oxygen isotope records of monsoon dynamics from China, demonstrating an abrupt strengthening of the summer monsoon at 12 kyr BP and an associated increase in precipitation and in lake levels between 11 and 8 kyr BP, followed by the stepwise attenuation of the monsoon circulation and climate aridization towards the modern levels. The records from the neighboring areas of Kazakhstan and Russia, situated west and north of Hoton-Nur, demonstrate spatially and temporally different Holocene vegetation and climate histories, indicating that the Altai Mountains as a climate boundary are of pivotal importance for the Holocene environmental history of Central Asia. For example, during the first half of the Holocene the areas west of the Mongolian Altai range was drier than present whereas the areas east of the range was moister than present. A shift towards wetter conditions occurred in the western region only during the second half of the Holocene, when the mid-latitudinal belt, stretching from the Baltic Sea to Kazakhstan and southern Siberia, came under the control of the Atlantic air masses. At the same time conditions of the Mongolian Altai became relatively dry. The pollen records from the northern region, including Russian Altai display two precipitation maxima during past 12 kyr. In line with the records from the eastern and western regions, the early Holocene (summer monsoon-associated) maximum was more pronounced in the eastern part of the northern region and the late Holocene (westerly-associated) maximum could be better seen in its western part.

    Toxocariasis is one of the most important zooanthroponotic natural-focal parasitic diseases in the Republic of Altai. The prevalence of their invasion among the inhabitants of the Republic has increased by more than 7 times. The data of the authors' observations ofToxocara infection in animals (cats, dogs), soil contamination with helminth eggs, and prevalence of human toxocariasis in the Republic of Altai, by considering the results of tests for antibodies against its pathogen in the inhabitants of the region, were automatically processed using geoinformation mapping simulation, which yielded a mapping model to rank the region's area by morbidity rates. The use of up-to-date computers and geo information systems makes it possible to systematize information on this invasion and to see major foci of the disease to reveal the reasons for their assignment to the specific type of the region's landscape.

    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.

    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.

    Human activities have significantly altered atmospheric Pb concentrations and thus, its geochemical cycle, for thousands of years. Whereas historical Pb emissions from Western Europe, North America, and Asia are well documented, there is no equivalent data for Eastern Europe. Here, we present ice-core Pb concentrations for the period 1680-1995 from Belukha glacier in the Siberian Altai, assumed to be representative of emissions in Eastern Europe and the Altai. Pb concentrations and (207)Pb/(206)Pb ratios were strongly enhanced during the period 1935-1995 due to the use of Pb additives in Russian gasoline mined in the Rudny Altai. Comparable to Western Europe and North America, Eastern European Pb emissions peaked in the 1970s. However, the subsequent downward trend in Eastern Europe was mainly caused by the economic crisis in the U.S.S.R. and not by a phase-out of leaded gasoline. Pb concentrations in the period 1680-1935, preceding the era of intensified industrialization in Russia, reflect the history of local emissions from Rudny Altai mining and related metallurgical processing primarily for the production of Russian coins. During this time, Altai ore Pb contributed about 40% of the regional atmospheric Pb. PMID:22420491

    On the Western Altai, 50 km southward from the city of Ust-Kamenogorsk, at the same latitude as the Ak-Baur sanctuary, another interesting complex of ancient objects was examined in 2006-2007. This complex consists of a grotto, ``spotty'' stone and platforms with holes. In the grotto anthropomorphic and geometric drawings madein red ochre were found. The centre of the composition schematically represents human figures with joined hands. One kilometer to the west from the complex there is a sharp-pointed mountain Zhangiztas. In its bottom part a ``zoomorphic'' ledge is visible; it reminds a sideview of a ``head with the opened mouth and tongue''. Observing the sunset on the days of equinox, one can watch the Sun ``setting down'' on the top of Mt. Zhangistas, then ``sliding'' along the right-side slope and finally ``rolling into the mouth''; in other words, it is ``swallowed by a monster''. The ``zoomorphic'' peculiarity of the mountain outliers (monad nocks) of the Monastyri complex as a whole and of their separate rocky juts was comprehended in the antiquity; the evidence for it is the presence of manmade holes near them; these holes might have an astronomical meaning.

This paper presents the results of the study of seasonal changes in the isotopic composition of precipitation and surface layers of warm and cold glaciers in Central Altai. The isotopic composition of warm glaciers (North Chui Ridge) significantly (by more than 6.5 ) facilitated relatively mean value of ice core layers from cold Belukha glacier. This difference primarily may be due to: 1) with multiple cryogenic isotope fractionation of warm glaciers surface, which leads to the formation of significantly lighter ice isotopic composition; 2) accumulation of the edge portion of the warm glaciers occurs mainly due to the winter solid precipitation. The isotopic composition of summer precipitation (July 2013) in the Central Altai ranged from -7.55 to -10.28 0/00for ?18O and from -135.20 to -136.04 0/00 for ?D, which indicates that the formation of precipitation fallen on the earth surface of precipitated on the surface glacier great contribution moisture exchange processes arising from the passage of moist Atlantic air masses over the territory of the Aral- Caspian region. Integrated use of data on the trajectory of air masses (model HYSPLIT), synoptic situation and the isotopic composition of precipitation can detect features of the formation of precipitation . For example , it was shown to cause rainfall in the Central Altai July 16, 2013 was the formation of occlusions of Altai, and the moisture in the air mass moving over the continent to weak evaporative fractionation .

    Alluvial fans in southern Monglia occur along a group of narrow discontinuous mountain ranges which formed as transpressional uplifts along a series of strike-slip faults. They provide information on the nature of neotectonic activity in the eastern Gobi Altai range and on palaeoclimate change. Alluvial fan formation was dominated by various geomorphological processes largely controlled by climatic changes related to

    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).

    We investigated the antihypoxic effect of herb mixture from the Altai in an experiment with rats. This mixture of herbs contains bioflavonoids. Also, it has antioxidant, anti-inflammatory, antispasmodic, angioprotective and antiplatelet properties. The animals received decoction of herbs into the stomach through a tube. Courses lasted 3, 7, 14 and 21 days. Resistance to acute hypobaric hypoxia evaluated by time of animal life in modeling rise to a height of 11,500 meters above sea level. In result, a significant antihypoxic effect was observed in rats treated with decoction of herbs for 21 days. Shorter courses of treatment were not effective. PMID:24000712

    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.

    This study investigates glacier dynamic and climatic variations in the southeastern part of the Russian Altai (SE Altai) during the last 7000 years. Recent glacier retreats and ice melting in moraines has led to exhumation of organic material allowing the possibility of radiocarbon dating. We report here 57 new radiocarbon dates from wood remains buried by moraines and from proglacial forefields, from peat layers and lacustrine sediments that cover moraines, from dead trees at the upper tree limit, and from rock glaciers on trough slopes from six glacial valleys in the North Chuya Range, SE Altai. Such a numerous dataset for the vast but unified in neotectonic and climatic conditions area is presented for the first time the history of research in the Altai. Together with 62 previously published radiocarbon ages, mainly of fossil soils and peat layers in the foot of the ranges in SE Altai, they form the basis for understanding the relative magnitudes and timing of the most important glacial and climatic events of SE Altai. New data refute the traditional concept of the Russian Altai Holocene glaciations as a consecutive retreat of the late Würm glaciers and argue their complete degradation at the head of trough valleys at least 7000 cal. years BP. Moraine complexes of three Holocene glacial stages are morphologically expressed in trough valleys of the North Chuya range. They correlate with three identified periods of glacial advances: from 4900 to 4200 cal. years BP (Akkem stage), from 2300 to 1700 cal. years BP (Historical stage) and in the 13th-19th centuries (Little Ice Age (LIA) or Aktru stage). The coincident extremes of lowering temperature and increasing precipitation during the Akkem stage led to abrupt glacier advances and forming of the most remote moraine complexes downstream in the valleys. Following glacier advances had distinctly smaller magnitudes. In addition to the radiocarbon data, the time limits of the Historical stage were defined more precisely using dendrochronological and archaeological data from Scythian burials of Pazyryk culture in SE Altai. Repeated forest regrowth in the presently glaciatiated area indicates significant retreat or even complete glacier degradation during interstage warming. The decreases of glacier length in the following stages argues for intensification of aridity in the SE Altai during the second half of the Holocene. The thermal minimum in the middle of 19th century, the greatest in the last millennium, did not positively influence the mass balance of glaciers, which also supports this conclusion.

    Background Virtually all well-documented remains of early domestic dog (Canis familiaris) come from the late Glacial and early Holocene periods (ca. 14,000–9000 calendar years ago, cal BP), with few putative dogs found prior to the Last Glacial Maximum (LGM, ca. 26,500–19,000 cal BP). The dearth of pre-LGM dog-like canids and incomplete state of their preservation has until now prevented an understanding of the morphological features of transitional forms between wild wolves and domesticated dogs in temporal perspective. Methodology/Principal Finding We describe the well-preserved remains of a dog-like canid from the Razboinichya Cave (Altai Mountains of southern Siberia). Because of the extraordinary preservation of the material, including skull, mandibles (both sides) and teeth, it was possible to conduct a complete morphological description and comparison with representative examples of pre-LGM wild wolves, modern wolves, prehistoric domesticated dogs, and early dog-like canids, using morphological criteria to distinguish between wolves and dogs. It was found that the Razboinichya Cave individual is most similar to fully domesticated dogs from Greenland (about 1000 years old), and unlike ancient and modern wolves, and putative dogs from Eliseevichi I site in central Russia. Direct AMS radiocarbon dating of the skull and mandible of the Razboinichya canid conducted in three independent laboratories resulted in highly compatible ages, with average value of ca. 33,000 cal BP. Conclusions/Significance The Razboinichya Cave specimen appears to be an incipient dog that did not give rise to late Glacial – early Holocene lineages and probably represents wolf domestication disrupted by the climatic and cultural changes associated with the LGM. The two earliest incipient dogs from Western Europe (Goyet, Belguim) and Siberia (Razboinichya), separated by thousands of kilometers, show that dog domestication was multiregional, and thus had no single place of origin (as some DNA data have suggested) and subsequent spread.

    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.

    We examined microorganisms and pollen in a pit (4.5 m deep) and a shallow ice core (25.01 m long) from Sofiyskiy glacier in the Altai mountains of Russia for potential use in dating ice cores from a mid-latitude glacier. The ice-core and pit samples contained various green algae, cyanobacteria, bacteria, fungi and pollen. In the vertical profiles of the pit, algal biomass peaks corresponded to high ?18O layers and Pinaceae pollen peaks, suggesting that these algae grew during the melt season. In contrast, the layer with the lowest ?18O contained almost no algal cells. Major peaks of the cyanobacteria, bacteria and a fungus roughly corresponded to those of the algae. However, seasonal changes in these microorganisms became indistinct deeper in the core, as did the seasonal variation in ?18O and major ions, most likely due to heavy meltwater percolation and/or post-depositional decomposition. In contrast, clear seasonal cycles were evident in the algal biomass and pollen in snow samples. Assuming that the peaks of the snow algae and Pinaceae pollen marked summer layers and that the layers with almost no snow algae represented the winter layers, we estimated that the ice core contained 16 annual layers (1985-2001). The mean annual mass balance for the period was estimated to be 1.01 m w. e. The value agreed well with those estimated from stake measurements, indicating that snow algae and pollen could provide reliable boundary markers of annual layers in the ice cores of this region.

    Soils of the southwestern part of the Dzhulukul Depression in Ulagan district of the Altai Republic have been studied. They belong to two soil divisions: Al-Fe-humus soils (with various types of podburs) and iron-metamorphic soils (rzhavozems). The soils within the eluvial part of the studied catena—iron-illuvial soddy podburs—are developed from the residuum of magmatic and metamorphic rocks with high (up to 80 vol %) content of gravels and coarse rock fragments. Their high porosity favors downward migration and precipitation of humus-iron compounds on the surface of gravels and mineral grains in the illuvial horizon. The soils of the accumulative part of the catena—permafrost-affected raw-humus pod-burs and gleyic podburs)—are developed from moraine deposits of loamy-sandy texture with up to 30 vol % of gravels. In these soils, the features of the Al-Fe-humus migration are weakly pronounced; the soils are underlain by the waterproof frozen horizon (permafrost), have high humus content, and have thixotropic properties in the lower horizons. Their reaction is slightly acid to neutral, and their base saturation is up to 80%. These characteristics do not meet the criteria of podburs as defined in the new Russian soil classification system. Their origin may be related to the local mixing of weathering products of different bedrock materials, including magmatic, metamorphic, and sedimentary rocks during the deposition of moraine sediments. Iron-metamorphic soils (rzhavozems) are formed on convex parts of slopes from the residuum and colluvial derivatives of magmatic and metamorphic rocks (granite, metamorphic slates, red-colored sandstone, etc.). A distinctive feature of these soils is their ocherous-brown color and a considerable content of gravels in the entire profile. The chemical properties of rzhavozems resemble those of the Al-Fe-humus soils of automorphic positions: acid and slightly acid reaction, low base saturation, and a relatively high content of organic carbon in the organic and mineral horizons.

    The Mengku iron deposit (110 Mt at 44% Fe) in the eastern extension of the Rudnyi Altai mineral belt, Xinjiang, NW China, is hosted in an Early Devonian volcano-sedimentary sequence affected by prograde skarn formation (clinopyroxene, garnet, scapolite and albite) and retrograde alteration (actinolite, epidote, chlorite and apatite). Ore minerals are magnetite, with minor chalcopyrite, pyrrhotite and pyrite. Gangue minerals include predominantly diopside, andradite, epidote, chlorite, quartz and calcite. Fluid inclusions in garnet and clinopyroxene yield homogenization temperatures (Th) of 241-500 °C, and salinities of 9.6-13.0 wt.% NaCl equivalent. Fluid inclusions in quartz consist of two varieties: (1) liquid-vapor-solid inclusions with (Th) of 348-458 °C and salinities of 38.2-57.1 wt.%, and (2) two-phase inclusions with (Th) of 166-382 °C and salinities of 9.6-13.0 wt.% NaCl equivalent. Two-phase inclusions in calcite vary from 145 to 265 °C, with salinities of 1.2-9.6 wt.% NaCl equivalent. The fluid evolution progressed from high temperature and moderate salinity (prograde skarn stage) to moderate T and salinity (retrograde stage), to low T and salinity (sulfide stage). Stable isotope data of quartz and calcite (-84‰ to -110‰ ?D, 5.5-7.0‰ ? 18O SMOW, and -3.8‰ to -6.1‰ ? 13C PDB) reflect late-stage interaction of meteoric water with granitic rocks. Skarn formation was likely related to a Late Devonian tonalite (378 ± 7 Ma, U-Pb zircon age). The geological and geochemical evidence suggests magnetite skarn formation from granite-related fluids which reacted with andesitic to mafic volcanics and their intercalated carbonate beds and lenses, contrary to earlier interpretations of the deposit as of synsedimentary-exhalative origin or related to iron-oxide magma.

    We report the first high-resolution (with intervals ca. 20-50 years) late-Holocene (4200 yr BP) pollen record from Lake Teletskoye, Altai Mountains, obtained from the underwater Ridge of Sofia Lepneva in 2006 (core Tel 2006). The study presents (i) the results of palynological analysis of Tel 2006; (ii) the results of spectral analysis of natural cycles based on the periodical fluctuation of taiga-biome curve; and (iii) quantitative reconstructions of the late-Holocene regional vegetation, woody coverage and climate in northern part of the Altai Mountains in order to define place of Northeast Altai on the map of the late-Holocene Central Asian environmental history. Late Holocene vegetation of the northeastern part of Altai recorded in Tel 2006 core is characterized by spread of dark-coniferous forest with structure similar to modern. Dominant trees, Siberian pine (Pinus sibirica) and Siberian fir (Abies sibirica), are the most ecological sensitive taxa between Siberian conifers (Shumilova, 1962), that as a whole suggests mild and humid climatic conditions during last 4200 years. However, changes of pollen taxa percentages and results of numerical analysis reveal pronounced fluctuation of climate and vegetation. Relatively cool and dry stage occurred prior to ca. 3500 cal yr BP. Open vegetation was widespread in the region with maximum deforestation and minimal July temperatures between 3800-3500 cal yr BP. Steppe-like communities with Artemisia, Chenopodiaceae and Cyperaceae could grow on the open sites around Lake Teletskoye. Reconstructed woody coverage is very low and varies between 29-35%. After ca. 3500 cal yr BP the area of dark-coniferous mountain taiga has significantly enlarged with maximums of woody coverages and taiga biome scores between ca. 2470-1040 cal yr BP. In the period of ~3500-2500 cal yr BP the averages July temperatures increased more than 1 0C. Climate became warmer and wetter. During last millennium (after 1040 cal yr BP) average July temperatures fell to 17.04 0C. Minimums of July temperatures related to AD1560-1650 and may reflect Little Ice Age in the northeastern Altai. This assumption is in an agreement with previous data from Lake Teletskoye (core Tel 2001-02 covered last 1000 years) where the period with relatively cold and dry climate was revealed between AD1560 and 1820 (Andreev et al., 2007). The coldest period in Tuva according to dendrochronological data (Myglan, Oidupaa, Vaganov, 2012) was in 17-19 centuries with minimum of June-July temperatures at AD1778-1819. Pollen records from the Chuya basin (southeastern part of Russian Altai) revealed the onset of LIA around AD1600 (Schluetz&Lehmkuhl, 2007). Open steppe-like vegetation slightly enlarged after ~AD1700 with increasing of continentality. Modern Index of Continentality mapping for the Altai Mountains is in range of 50-59 (Grieser et al., 2006). The average Index of Continentality calculated for last 30 years using data from Barnaul meteostation, located 300 km northwest of the lake in forest-steppe zone, is 40.6; the average Index of Continentality for Yailu meteostation (north shore of Lake Teletskoye) is 20. Index of Continentality reconstructed from Tel 2006 varies in limits of 48-58 and obviously shows regional but not local situation. Throughout the Tel 2006 record woody coverages vary between 29.0% at the 3890 cal yr BP and 50.3% at the AD1830. Woody coverage greater than 65% is associated with the Siberian mid-latitudinal zonal taiga. Areas north and south of the taiga zone have moderate forest coverage (25-45%), suggesting greater landscape openness (Tarasov et al., 2007). Regarding to VCF data, modern woody cover in 20 km around the lake is ca. 55% (http://glcf.umiacs.umd.edu/data/vcf). Reconstructed woody coverage is lower than observed and reflect probably forest development in the whole lake catchment basin. Spectral analysis of Tel 2006 data demonstrates periodic changes of taiga-biome curve of ~1050, ~470 and ~210 years intervals during the Late Holocene. Kravchinsky et al. (2013) presume that the 1000- and 500-

    Two quantitative methods were used to reconstruct paleoenvironments and vegetation in the Altai-Sayan mountains, Central Asia, during the Holocene. The 'biomization' method of Prentice et al (1996 Clim. Dyn. 12 185-96), applied to the surface pollen record, worked fairly well in the reconstructions of current vegetation. Applying this method to fossil pollen data, we reconstructed site paleovegetation. Our montane bioclimatic model, MontBioCliM, was used inversely to convert site paleovegetation into site paleoclimates. The differences between site paleo and current climates served as past climate change scenarios. The climatic anomalies for 2020, 2050, and 2080 derived from HadCM3 A1FI and B1 of the Hadley Centre, UK, served as climate change scenarios in the 21st century. MontBioCliM was applied directly to all climate scenarios through the Holocene to map past and future mountain vegetation over the Altai-Sayan mountains. Our results suggest that the early Holocene ca 10 000 BP was cold and dry; the period between 8000 and 5300 BP was warm and moist; and the time slice ca 3200 BP was cooler and drier than the present. Using kappa statistics, we showed that the vegetation at 8000 BP and 5300 BP was similar, as was the vegetation at 10 000 BP and 3200 BP, while future vegetation was predicted to be dissimilar to any of the paleovegetation reconstructions. The mid-Holocene is frequently hypothesized to be an analog of future climate warming; however, being known as warm and moist in Siberia, the mid-Holocene climate would likely impact terrestrial ecosystems differently from the projected warm and dry mid-century climate.

    A new evolutionary genetic phenomenon - increase in the number of B-chromosomes (almost threefold) accompanied by change in B chromosome morphotypes - was discovered in the Artybash population of East Asian mouse Apodemus peninsulae (Mountain Altai) over a historically short period (22 years), comparable with a small number of mouse generations (ten generations). The process of increase in the number of A. peninsulae B-chromosomes in Mountain Altai has been monitored over 26 years (1980, 1986, 1988, 1990, 2002, and 2006). A concept of a new type of genomic mutations - mutations in the number of B-chromosomes-has been substantiated. The phenomenon of genomic mutations in pro-B-chromosomes has been discovered only in the Mountain Altai populations. This region differs from the remaining A. peninsulae dwelling localities by pollution with unspent liquid propellant (UDMH, heptyl). It is assumed that the variants of mouse B chromosome system in the studied A. peninsulae populations in the overall habitation area over long-term periods are likely to remain relatively stable and that their variation is controlled by homeostatic processes. Disturbance of these processes, in particular, due to anthropogenic load, can disrupt the cyclic pattern of increase and decrease in the number of A. peninsulae B-chromosomes in individual years.

    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.

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

    Chernykh, Alexandr

    2013-04-01

    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.

  15. Microclimate affects soil chemical and mineralogical properties of cold-alpine soils of the Altai Mountains (Russia)

    Precipitation and temperature particularly influence soil properties by affecting the type and rates of chemical, biological, and physical processes. To a great extent, element leaching and weathering rates are governed by these processes. Vegetation growth and decomposition, that depend on temperature and the other environmental factors, influence weathering reactions through the production of acidity and organic ligands that may promote chemical weathering and subsequent elemental leaching. The present work focuses on cold-alpine soils of the Altai Mountains (Siberia, Russia). The investigated field site (2380 m asl) is characterised by cold winters (with absolute minimum temperatures of -50°C; a mean temperature in January is -21°C) and cool summers (+8°C mean temperature in July). The mean annual temperature is -5.4°C. Annual precipitations are relatively low (500 mm with 20% of precipitation in July). Permafrost is widespread and occurs sometimes at a depth of 30 to 50 cm. Several studies have shown the influence of slope aspect and the resulting microclimate on soil weathering and development. There is however no unanimous agreement whether weathering is more intense on north- or south-facing slopes and whether small differences in thermal conditions may lead to detectable differences. Higher temperatures do not necessarily lead to higher weathering rates in cold alpine regions as shown by previous investigations in the European Alps. Water fluxes through the soils seemed to be more important. We consequently investigated soils in the cold-alpine environment of the Central Altai Mountains on a very small area close to a local glacier tongue. Half of the investigated soil profiles were south-facing (5) and the other half north-facing (5). The soils have the same parent material (mica-rich till), altitude, topography, and soil age. The vegetation is alpine grassland that is partially intersected with some juniper and mosses, which portion in the soil surface increases towards the hill footslope. Soil chemical properties such as organic C, N, soil organic matter quality (using DRIFT), pH value, (oxy)hydroxides, total elemental contents (XRF), and soil mineralogy (using diagnostic treatments and XRD) were determined. The age constraint of the site was given by geomorphic studies, 14C dating of a nearby peat-bog and of the stable organic matter fraction of the soils. The soils have a Holocene age. The results showed astonishingly clearly - similarly to the European Alps - that the south-facing soils have a lower weathering state. This is expressed by statistically significant lower pH-values, more oxalate and dithionite extractable Fe, Al, Mn, and Si contents, higher C concentrations and stocks and even lower total Si- and Ca-contents at north facing sites. A similar weathering trend was also obtained from the weathering index (Ca+K)/Ti. The geochemical evolution of the soils seems also here to be enhanced at north facing sites, although very severe climatic conditions prevail. We must assume that weathering is not limited by temperature in the active layer but rather by soil moisture that seems to be higher during the warmer period in the north-facing soils. This is furthermore confirmed by the appearance of slightly evident features of an umbric soil horizon at the north-facing sites at the hill footslope. Furthermore, biodegradation seem to be less pronounced on north-facing sites compared to south-facing sites. Poorly degraded organic matter is consequently accumulated on north-facing sites. This finally gives rise to more organic and mobile organic ligands that promote weathering processes.

    During field work in 2009 were sampled cores of bottom sediments of Lake Shira (Khakassia) and Lake Kucherla (Altai). Sediments contain annually laminated layers (varves). The average thickness of layers in the Lake Shira sediments is 1.3 mm, in the Lake Kucherla sediments - 2.3 mm. Cores were impregnated with epoxy resin and then are prepared solid samples thickness of 2 mm for X-ray scan. X-ray scanning was carried out in the Siberian Synchrotron Radiation Center (Budker Institute of nuclear physics SB RAS, Novosibirsk) using the excitation energies of 18 and 24 keV by the methods described in papers [1, 2]. Scanning X-ray fluorescence analysis on synchrotron radiation (SR-XRFA) as a high-efficiency method of microelement analysis is adapted to determine more than 35 elements with minimal step 0.1 mm. A detailed study of the varves with a spatial resolution of 100 microns showed seasonal variation of trace-element composition within the annual layers. It was counting the number of annual layers using the geochemical variations of sediment. Key geochemical indicators of terrigenous (Ti, Ga, Rb, Sr, Zr) and organogenic (Zn, Br, U) components of sediments were identified. Comparison of meteorological data for the past 50 years with the lithological and geochemical parameters of sediments showed a stable dependence of trace-element composition of sediments with the climate variation in the region. Investigated lakes contain high-resolution records of regional climate changes. [1] K.V. Zolotarev et all. Nucl. Instrum. and Meth. A470 (2001),376. [2] A.V. Daryin et all. Nucl. Instrum. and Meth.

    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

    Pollen spectra circulating in the atmosphere contain the important information about primary biological aerosol particles (PBAP), worldwide interest in which has significantly increased in recent decades [Despres, 2012]. It is related to the fact that many researchers suggest primary aerosols as a condensation nucleus significantly affected on the formation of clouds and precipitation and, consequently, on the hydrological cycle and climate, especially at the regional level [Andreae et al., 2008; Poschlet et al., 2010; Prenni et al., 2009]. We present the comparison of pollen spectra obtained during the dry and wet atmospheric deposition in Altai Krai (Russia) and identification of the sources/regions of their receipts. Altai Krai is located in the center of the Eurasian continent, at the border of several natural and climatic zones. A significant part of the region's territory is characterized as a forest-steppe zone with a lot of natural and anthropogenic landscapes, accompanied by continental climate. It provides a rich diversity of natural vegetation and cultural associations. During last 10 years pollen grains has been monitored in the airspace of Barnaul city (the capital of Altai Krai) located in the central part of the forest-steppe zone). During the monitoring, the attempts to determine the origin of pollen spectra (local or introduced) were made as well. In the long-term average dates of the first wave of dusting in the spring season 2014 Burkard pollen traps were used in order to monitor the airspace in Barnaul, namely dry deposition of pollen grains [Nenasheva, 2013]. To estimate the wet deposition PBAP (pollen), which can reach 80% in the middle latitudes, precipitation sampler were installed close to Burkard pollen traps in order to sample precipitation. The samples were filtered through a filter having a pore diameter of 1 µm, then prepared and examined for the presence of pollen grains. The comparison of the results of pollen analysis of 10 samples of precipitation and the samples obtained by Burkard pollen traps for dates with precipitation from April to May 2014 showed the following. Pollen spectra isolated from the different types of precipitation (dry and wet) correspond to each other in taxonomic composition in 85% of cases. For example, isolated pollen spectra for 11 April, considering the wet deposition, is characterized by the presence of Pinus sylvestris. According to Burkard pollen traps, pollen grains Pinus sylvestris were also identified in the air. To identify the sources of pollen grains, we estimated the long-term average date of pine dusting on the territory of Barnaul. During the period from 2004 till 2013 it accounts for the end of the second decade of May. Thereby, isolated pollen grains are unlikely to have local origin. To confirm this fact, backward trajectories were calculated on April 11, 2014 using the model HYSPLIT [http://ready.arl.noaa.gov/HYSPLIT.php]. Trajectories showed the southwest transport of pollen to have been identified in the atmospheric surface layer from the territory in the south of Altai Krai, including the surroundings of Lake Zaisan (Kazakhstan), where earlier dusting of pine could be observed mentioned.

    The genetic variability in seven yak populations from the Sayan-Altai region and in F1 hybrids between yak and cattle (khainags) was investigated with the help of a technique that involves the use of inter simple sequence repeat (ISSR) markers generated with PCR primers (AG)9C and (GA)9C. Samples for the analysis were collected in Mongolia, Tuva, and Altai from 2008 through 2012. The examined yak populations differed in in the presence/absence of ISSR fragments, as well as in their frequency. In total, 46 ISSR fragments were identified using two marker systems; the proportion of polymorphic loci constituted 76% and 90% for the AG-ISSR and GA-ISSR markers, respectively. For the total sample of yaks, total genetic diversity (Ht), within-population diversity (Hs), and interpopulation diversity (Gst) constituted 0.081, 0.044, and 0.459 for the AG-ISSR and 0.137, 0.057, and 0.582 for the GA-ISSR markers, respectively. Based on ISSR finger printing, species- and breed-specific DNA patterns were described for the three groups of animals (yaks, cattle, khainags). For the domestic yak, the species-specific profile was represented by eight ISSR fragments. Genetic relationships between the yak populations, cattle breeds, and khainags were examined with the help of four different approaches used in the analysis of population structure: estimation of phylogenetic similarity, multidimensional scaling, principal component analysis, and cluster analysis. Clear evidence on the differentiation of the populations examined at the interspecific, as well as at intraspecific, level were obtained. Similar (relative); as well as remote (isolated), yak populations were identified. Khainags occupy an intermediate position between yak and cattle. However, the data on the ISSR-PCR marker polymorphism (genome polymorphism, population structure).indicate that part of the analyzed khainag genome was more similar to the yak genome than to the cattle genome.

  20. Geochemical and detrital zircon studies of meta-sedimentary rocks from the Teletsk and Ulagan blocks, Russian Altai: Implications on their tectonic affinity and geodynamic evolution

    A combined whole-rock geochemical and detrital zircon geochronological and Hf-isotope study was conducted on meta-sedimentary sequences of the Teletsk and Ulagan blocks in order to trace their provenance, depositional setting and tectonic affinity. Samples from the Teletsk and Ulagan blocks underwent epidote-amphibole- and greenschist-facies metamorphism, respectively, but all of them show comparable geochemical characteristics. They are characterized by high Al2O3/SiO2 ratios and ICV (Index of Chemical Variability) values, while (Gd/Yb)N ratios and REEs compositions are comparable to those of the upper continental crust, indicating that their protoliths were immature and probably deposited proximal to the source areas without significant sedimentary sorting. The low CIA (Chemical Index of Alteration) values for these samples (47.3-74.5 and 52.5-74.5, respectively) further suggest that the source rocks underwent mild to moderate chemical weathering. All the samples show major elements (e.g., Al2O3/TiO2, TiO2/Fe2O3T, Fe2O3T/Al2O3), REEs concentrations, HFSEs and transition elements compositions between the typical andesites and granites, but deviate from those of basaltic rocks, implying that intermediate-felsic rocks served dominant sources during the sedimentation. These geochemical characteristics are consistent with the continental island arc setting, which is discriminated by the TiO2, Al2O3 and Fe2O3T + MgO concentrations higher than those of passive marginal depositions, but La/Sc, Ti/Zr, La/Th, La/Sc and Zr/Th ratios comparable to those of depositions in continental island arc settings. Two samples from the Teletsk and Ulagan blocks yield similar detrital zircon age spectra, with the most prominent population of ca. 620-470 Ma old and a subordinate one of ca. 943-743 Ma old. Comparison with surrounding tectonic units shows that the Tuva-Mongolian terrane and surrounding island arcs in western Mongolia probably provided substantial sources to the protoliths. The similarities in geochemical compositions and detrital zircon patterns with those for the Altai-Mongolian terrane suggest that the Teletsk and Ulagan blocks possibly represented the northern margin of this terrane with different crustal levels. Our study places further constraints that the whole Altai-Mongolian terrane possibly represented a large subduction-accretion complex built upon the active margin in the western Mongolia during the early Paleozoic.

    The Chinese Altai is a key region to decipher the accretionary history of the gigantic CAOB, one of the largest accretionary orogenic belts on the earth. However, its Paleozoic tectonothermal events and tectonic implications remain debated. In this study, a suite of igneous rocks, including high Mg dacite of the Kangbutiebao Formation and the associated gneissic granite, have been studied for their petrogenesis and tectonic implication. The high Mg dacite is dated at 400±2Ma, which broadly resembles the emplacement age of the high Mg gneissic granite of 406±9Ma, possibly suggesting that they were generated in a common tectono-magmatic event. Both rocks have zircon inheritances of ~500 Ma, which is consistent with the age of predominant zircon population for in the widespread Habahe sequence, indicating that their precursor magmas were probably mainly derived from the Habahe sediments. The high-Mg rock association has similar REE and trace element patterns to those of the Habahe sediments and they plot close to the field of the Habahe sediments in Th/Ta versus La/Ta diagram. They have high A/CNK ratios (1.33-2.05), supporting their source was sedimentary rocks. In Ba/Th versus (La/Sm)N diagram, these rocks are characterized by high La/Sm ratios which suggests a greater contribution of sediments rather than altered oceanic crust in the magma generation. However, the high Mg# values (~51) of the studied rocks argue against derivation purely from remelting of Habahe sediments. In order to explain the high Mg# values (~51) of these rocks, the participation of mantle-derived melt into the precursor magma is considered. Zircons from this rock association mostly have ?Hf(t) values from +0.85 to +9.71, supporting the involvement of juvenile materials in the magma generation. Samples from the high Mg rock association fall in the same field as the sanukitoids in TiO2 versus Mg# and Sr/Y versus Y diagrams, plot in the fractional crystallization trend of differentiated sanukitoids in Harker diagram. Similar to the sanukitoids in the Setouchi area, our high Mg rock association also involved melting of subducted sediments in a hot subduction regime. Combined with previous work, a ridge subduction regime is used to interpret the early Devonian tectonic evolution of the Chinese Altai.

  2. 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?

    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.

    August 2, 1999, marks the spring equinox for the martian southern hemisphere. It is also the start of autumn for regions north of the equator. Winter in the south has finally come to a close, and the seasonal frosts of the wintertime south polar cap are retreating. Small, local dust storms frequently occur along the margins of the polar cap, as the colder air blowing off the cap moves northward into warmer regions.

    The wide angle camera view of Mars shown here was obtained by the Mars Global Surveyor Mars Orbiter Camera in late July 1999, about 1 week before the start of southern spring. The frosty, retreating south polar cap (white) is seen in the lower quarter of the image, and wisps of dust storm clouds (grayish-orange in this view) occur just above the cap at the lower left. The southern most of the large environmental changes volcanoes, Arsia Mons, is seen at the upper left. Arsia Mons is about 350 kilometers(220 miles) across.

    Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, CA and Denver, CO.

    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). The data were acquired and provided by the Satellite Applications Center in Pretoria, South Africa. Image courtesy Gene Feldman, SeaWiFS Project and Orbital Sciences

    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.

    1987-01-01

    The ability to fractionate nucleic acids and to determine which of them has sequences complementary to an array of DNA or RNA molecules is one of the most powerful tools of molecular biology. The Southern blot, named for its inventor, is a method for transferring size-fractionated DNA from a gel matrix to a solid support followed by hybridization to a labeled probe. The identical process for RNA playfully became known as the Northern blot. The use of dried agarose gels as the immobilized phase facetiously became known as the Unblot. As a reflection of the versatility of the technique, there are now dot blots, spot blots, slot blots, fast blots, Western blots and no doubt more to come. All are invaluable tools for investigating and analyzing mRNAs, clones, genes, fragments, flanking sequences, repetitive elements, and the like. For example, a Southern blot of a restricted genomic clone must be almost identical with a blot of similarly restricted genomic DNA, hybridized to the same probe. A cloned cDNA must be capable of hybridizing to the mRNA from which it supposedly was derived. Blots, then, are often key elements in establishing the identity of nucleic acids of interest.

    Over the past two weeks, heavy rains have inundated southern Russia, giving rise to floods that killed up to 83 people and drove thousands from their homes. This false-color image acquired on June 23, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite shows some of the worst flooding. The Black Sea is the dark patch in the lower left-hand corner. The city of Krasnodor, Russia, which was one of the cities hardest hit, sits on the western edge of the larger lake on the left side of the image, and Stavropol, which lost more lives than any other city, sits just east of the small cluster of lakes on the right-hand side of the image. Normally, the rivers and smaller lakes in this image cannot even be seen clearly on MODIS imagery. In this false-color image, the ground is green and blue and water is black or dark brown.

Kennedy and Lyndon Johnson declared war on rural poverty during their time in the White House, there has been an overriding concern with alleviating the persistently high levels of poverty in the American South. 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.

  1. Callisto's Southern Hemisphere

    1997-01-01

    These views of Callisto's southern hemisphere were taken by the Near Infrared Mapping Spectrometer just after closest approach in orbit G8 on May 6, 1997. These false color images show surface compositional differences, red = more ice, blue = less ice.

    The upper left view contains Buri, a crater with a diameter of about 60 km. In the infrared spectrum, Buri and the rays that extend from the crater have high abundance of water ice compared to the surrounding region. The center view, a large (200 km or 120 mile diameter) unnamed impact crater with a distinct ring or circle around it reveals a complex mix of ice and non-ice materials. This is possibly due to impact excavation of the ice-rich subsurface which suggests that the darker material is just a thin surface covering caused by impact debris or a lag deposit from which the ice has evaporated away. The infrared data shows spectral signatures for both sulfur and carbon as two potential materials which could play a part in the complicated make-up of Callisto's surface.

  2. Southern Oral History Program

    NSDL National Science Digital Library

    Since the rise of interest in social history in the United States, a number of academics and public citizens have remained committed to preserving the voices and perspectives of everyday people. The Southern Oral History Program (SOHP) at the University of North Carolina at Chapel Hill is a rather fine example of such a commitment. Founded in 1973, the SOHP has recorded over 2900 interviews with people from all walks of life, and their website contains a generous sampling of this material. First-time visitors may wish to start by watching "Spoken Memories", which provides a nice introduction to the history and work of SOHP. Afterwards, they can sample some of the online audio archives, or listen to the "Interview of the Month" feature. For those who wish to read as they listen, the interviews are complemented by transcripts in several different file formats. Visitors should also feel welcome to browse through the online finding aid to the SOHP's collection and offer their own feedback or inquiries.

  3. Fires in Southern California

    2007-01-01

    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. Fires northwest of Los Angeles seemed calmer at the time of this image than they were the previous day.

    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.

  5. Southern Dust Devils

    NASA Technical Reports Server (NTRS)

    2004-01-01

    [figure removed for brevity, see original site]

    Released 9 July 2004 The atmosphere of Mars is a dynamic system. Water-ice clouds, fog, and hazes can make imaging the surface from space difficult. Dust storms can grow from local disturbances to global sizes, through which imaging is impossible. Seasonal temperature changes are the usual drivers in cloud and dust storm development and growth.

    Eons of atmospheric dust storm activity has left its mark on the surface of Mars. Dust carried aloft by the wind has settled out on every available surface; sand dunes have been created and moved by centuries of wind; and the effect of continual sand-blasting has modified many regions of Mars, creating yardangs and other unusual surface forms.

    In our final dust devil image we are again looking at the southern hemisphere of Mars. These tracks occur mainly on the northeast side of the topographic ridges. Of course, there are many exceptions, which makes understanding the dynamics that initiate the actual dust devil cyclone difficult.

  6. Kinematic model of southern California

    SciTech Connect

    Weldon, R.; Humphreys, E.

    1986-02-01

    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.

  16. Unprecedented Fires in Southern Africa

    NASA Technical Reports Server (NTRS)

    2002-01-01

    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.

  17. Pteropods in Southern Ocean ecosystems

    NASA Astrophysics Data System (ADS)

    Hunt, B. P. V.; Pakhomov, E. A.; Hosie, G. W.; Siegel, V.; Ward, P.; Bernard, K.

    2008-09-01

    To date, little research has been carried out on pelagic gastropod molluscs (pteropods) in Southern Ocean ecosystems. However, recent predictions are that, due to acidification resulting from a business as usual approach to CO 2 emissions (IS92a), Southern Ocean surface waters may begin to become uninhabitable for aragonite shelled thecosome pteropods by 2050. To gain insight into the potential impact that this would have on Southern Ocean ecosystems, we have here synthesized available data on pteropod distributions and densities, assessed current knowledge of pteropod ecology, and highlighted knowledge gaps and directions for future research on this zooplankton group. Six species of pteropod are typical of the Southern Ocean south of the Sub-Tropical Convergence, including the four Thecosomes Limacina helicina antarctica, Limacina retroversa australis, Clio pyramidata, and Clio piatkowskii, and two Gymnosomes Clione limacina antarctica and Spongiobranchaea australis. Limacina retroversa australis dominated pteropod densities north of the Polar Front (PF), averaging 60 ind m -3 (max = 800 ind m -3) and 11% of total zooplankton at the Prince Edward Islands. South of the PF L. helicina antarctica predominated, averaging 165 ind m -3 (max = 2681 ind m -3) and up to >35% of total zooplankton at South Georgia, and up to 1397 ind m -3 and 63% of total zooplankton in the Ross Sea. Combined pteropods contributed <5% to total zooplankton in the Lazarev Sea, but 15% (max = 93%) to macrozooplankton in the East Antarctic. In addition to regional density distributions we have synthesized data on vertical distributions, seasonal cycles, and inter-annual density variation. Trophically, gymnosome are specialist predators on thecosomes, while thecosomes are considered predominantly herbivorous, capturing food with a mucous web. The ingestion rates of L. retroversa australis are in the upper range for sub-Antarctic mesozooplankton (31.2-4196.9 ng pig ind -1 d -1), while those of L. helicina antarctica and C. pyramidata are in the upper range for all Southern Ocean zooplankton, in the latter species reaching 27,757 ng pig ind -1 d -1 and >40% of community grazing impact. Further research is required to quantify diet selectivity, the effect of phytoplankton composition on growth and reproductive success, and the role of carnivory in thecosomes. Life histories are a significant knowledge gap for Southern Ocean pteropods, a single study having been completed for L. retroversa australis, making population studies a priority for this group. Pteropods appear to be important in biogeochemical cycling, thecosome shells contributing >50% to carbonate flux in the deep ocean south of the PF. Pteropods may also contribute significantly to organic carbon flux through the production of fast sinking faecal pellets and mucous flocs, and rapid sinking of dead animals ballasted by their aragonite shells. Quantification of these contributions requires data on mucous web production rates, egestion rates, assimilation efficiencies, metabolic rates, and faecal pellet morphology for application to sediment trap studies. Based on the available data, pteropods are regionally significant components of the Southern Ocean pelagic ecosystem. However, there is an urgent need for focused research on this group in order to quantify how a decline in pteropod densities may impact on Southern Ocean ecosystems.

  2. Classifying Southern Hemisphere extratropical cyclones

    NASA Astrophysics Data System (ADS)

    Catto, Jennifer

    2015-04-01

    There is a wide variety of flavours of extratropical cyclones in the Southern Hemisphere, with differing structures and lifecycles. Previous studies have classified these manually using upper level flow features or satellite data. In order to be able to evaluate climate models and understand how extratropical cyclones might change in the future, we need to be able to use an automated method to classify cyclones. Extratropical cyclones have been identified in the Southern Hemisphere from the ERA-Interim reanalysis dataset with a commonly used identification and tracking algorithm that employs 850hPa relative vorticity. A clustering method applied to large-scale fields from ERA-Interim at the time of cyclone genesis (when the cyclone is first identified), has been used to objectively classify these cyclones in the Southern Hemisphere. This simple method is able to separate the cyclones into classes with quite different development mechanisms and lifecycle characteristics. Some of the classes seem to coincide with previous manual classifications on shorter timescales, showing their utility for climate model evaluation and climate change studies.

  3. Geothermal resources of southern Idaho

    SciTech Connect

    Mabey, D.R.

    1983-01-01

    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.

    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.

    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 ...

  15. Airborne Particulates over Southern Africa

    NASA Technical Reports Server (NTRS)

    2001-01-01

    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.

  19. Combustion metamorphism in southern california.

    Bentor, Y K; Kastner, M

    1976-08-01

    In several places in Southern California bituminous sediments of the Monterey Formation-siliceous shales, phosphatic rocks, dolomites, and arkoses-were affected during the Pleistocene and as late as the l9th century by spontaneous subsurface combustion of organic matter, during which temperatures up to 1600 degrees C were reached. This oxidative heating (combustion metamorphism) affected rock complexes over areas of tens of square kilometers that tend to occur in clusters. As a result of these processes, the rocks recrystallized and partially melted to form pseudomagmas which intruded the country rocks. The chemical compositions of these melts differ from those of igneous magmas. Acid and intermediate siliceous melts as well as phosphatic melts have formed. These two types are generally immiscible. The following high-temperature minerals were determined: alpha- and beta-cristobalite, quartz, calcic plagioclase, diopsidic pyroxene, wollastonite, cordierite, graphite, fluorapatite, and fluorite; at lower temperature pyrite, gypsum, aragonite, calcite, jarosite, and hexahydrite crystallized.

    Castle, R O; Church, J P; Elliott, M R

    1976-04-16

    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.

    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

    2009-01-01

    Efforts to form this Alliance began in 2008 to showcase the impact testing capabilities within the southern United States. Impact testing customers can utilize SITA partner capabilities to provide supporting data during all program phases-materials/component/ flight hardware design, development, and qualification. This approach would allow programs to reduce risk by providing low cost testing during early development to flush out possible problems before moving on to larger scale1 higher cost testing. Various SITA partners would participate in impact testing depending on program phase-materials characterization, component/subsystem characterization, full-scale system testing for qualification. SITA partners would collaborate with the customer to develop an integrated test approach during early program phases. Modeling and analysis validation can start with small-scale testing to ensure a level of confidence for the next step large or full-scale conclusive test shots. Impact Testing Facility (ITF) was established and began its research in spacecraft debris shielding in the early 1960's and played a malor role in the International Space Station debris shield development. As a result of return to flight testing after the loss of STS-107 (Columbia) MSFC ITF realized the need to expand their capabilities beyond meteoroid and space debris impact testing. MSFC partnered with the Department of Defense and academic institutions as collaborative efforts to gain and share knowledge that would benefit the Space Agency as well as the DoD. MSFC ITF current capabilities include: Hypervelocity impact testing, ballistic impact testing, and environmental impact testing.

    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.

  4. Emissions from savanna fires in southern Africa

    NASA Astrophysics Data System (ADS)

    Sinha, Parikhit

    2004-12-01

    Airborne measurements are presented of emissions from savanna fires in southern Africa during the dry season. Measurements were obtained aboard the University of Washington Convair-580 research aircraft during the SAFARI 2000 field project in August and September 2000. Savanna fires in southern Africa emit a wide range of gaseous and particulate species including carbon, sulfur, nitrogen, halogen, and oxygenated compounds. Emission factors, emission ratios, and regional emissions of fifty trace gas and particulate species were derived, including eight species not previously reported in the literature (dimethyl sulfide, methyl nitrate, five species of hydrocarbons, and particles with diameters from 0.1--3 mum diameter). The physical, chemical, and radiative properties of the plume from a large savanna fire in South Africa are characterized, including plume dimensions, secondary formation of ozone and organic acids, oxidation of hydrocarbons, coagulation of particles, and gas-to-particle conversion in aged smoke. Numerous fires, thermodynamically stable layers aloft, and large-scale anticylonic flow result in high concentrations of air pollution distributed throughout the lower troposphere over southern Africa during the dry season. Average regional concentrations of CO (261 +/- 81 ppbv), SO2 (2.5 +/- 1.6 ppbv), O3 (64 +/- 13 ppbv), black particulate carbon (2.3 +/- 1.9 mug m-3), organic particulate carbon (6.2 +/- 5.2 mug m-3), total particle mass (26.0 +/- 4.7 mug m-3) are comparable to those found in polluted urban environments. The GEOS-CHEM model of tropospheric chemistry is used to characterize the transport of biomass burning emissions from southern Africa to the neighboring Atlantic and Indian Oceans during the dry season (May--October) of 2000. A large quantity of biomass burning emissions from southern Africa is transported westward over the latitudes 0--20°S to the southern Atlantic Ocean (˜40 Tg CO from May--October), contributing to a pollution anomaly in the south Atlantic Ocean. However, most of this material is transported back eastward over higher latitudes to the south (21--60°S) eventually reaching the southern Indian Ocean. As a result, ˜60 Tg of CO from biomass burning in southern Africa is transported eastward to the Indian Ocean across the latitude band 0--60°S from May--October, enhancing background CO concentrations by ˜4--13 ppbv per month over the southern subtropical Indian Ocean during the dry season.

    In the sorts of places you would least expect it, author Joel Greenberg reveals an abundance of life and bio-diversity in his A Naturalist's Tour of Southern Lake Michigan. 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.

    1987-01-01

    The role of medium-scale waves on three dynamic aspects of the Southern-Hemisphere general circulation is examined using data generated by the FGGE analyses of the ECMWF. The momentum and sensible heat transports by the medium-scale waves are discussed. The effects of medium-scale waves on atmospheric circulation of the Southern Hemisphere during the summer, in particular the vacillation of atmospheric energetics, are investigated. The horizontal and vertical structures and the transport properties of this wave regime and their relation to downstream development in the Southern Hemisphere are analyzed. It is observed that medium-scale waves supply about a half of the total eddy transport of sensible heat and momentum; the wave regime contributes to the time average of various energy contents and energetic components of atmospheric motion during the southern summer; and the wave regime is amplified during the developing stages of downstream development.

  17. Early German Plans for a Southern Observatory

    NASA Astrophysics Data System (ADS)

    Wolfschmidt, Gudrun

    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).

    A report is given of a project to use IRAS Band 3 (60 microns) and Band 4 (100 microns) observations to investigate the far-infrared properties of southern galactic molecular clouds. A method by which dust temperature and total gas column density can be estimated is presented. Results are tabulated for 65 prominent southern far-infrared sources. The dust temperatures are closely grouped between 30 and 50 K, while the column densities range between 2 x 10 to the 20th and 10 to the 22nd/sq cm. Maps of dust temperature and gas column density have been generated for two fields containing far-infrared sources to illustrate the effectiveness of this form of presentation.

    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.

  3. Primary production in Southern Ocean waters

    NASA Astrophysics Data System (ADS)

    Arrigo, Kevin R.; Worthen, Denise; Schnell, Anthony; Lizotte, Michael P.

    1998-07-01

    The Southern Ocean forms a link between major ocean basins, is the site of deep and intermediate water ventilation, and is one of the few areas where macronutrients are underutilized by phytoplankton. Paradoxically, prior estimates of annual primary production are insufficient to support the Antarctic food web. Here we present results from a primary production algorithm based upon monthly climatological phytoplankton pigment concentrations from the coastal zone color scanner (CZCS). Phytoplankton production was forced using monthly temperature profiles and a radiative transfer model that computed changes in photosynthetically usable radiation at each CZCS pixel location. Average daily productivity (g C m-2 d-1) and total monthly production (Tg C month-1) were calculated for each of five geographic sectors (defined by longitude) and three ecological provinces (defined by sea ice coverage and bathymetry as the pelagic province, the marginal ice zone, and the shelf). Annual primary production in the Southern Ocean (south of 50°S) was calculated to be 4414 Tg C yr-1, 4-5 times higher than previous estimates made from in situ data. Primary production was greatest in the month of December (816 Tg C month-1) and in the pelagic province (contributing 88.6% of the annual primary production). Because of their small size the marginal ice zone (MIZ) and the shelf contributed only 9.5% and 1.8%, respectively, despite exhibiting higher daily production rates. The Ross Sea was the most productive region, accounting for 28% of annual production. The fourfold increase in the estimate of primary production for the Southern Ocean likely makes the notion of an "Antarctic paradox" (primary production insufficient to support the populations of Southern Ocean grazers, including krill, copepods, microzooplankton, etc.) obsolete.

    Geophysical data from the southern Appalachians are generally interpreted in terms of Paleozoic collisional tectonics; the later effects of Mesozoic extension are often overlooked or downplayed. This paper reinterprets seismic reflection data from Georgia with the view that Mesozoic extension is responsible for most of the seismic reflection patterns one sees today. The interpretation suggests that geophysical data from a particular area reflect the most recent tectonic event rather than earlier and perhaps more geologically obvious events.

    The southern Pierre Auger observatory in Argentina takes data routinely now, and the first physics results have been obtained and published. The successful operation of the experiment is soon going to be enhanced by the low energy extension HEAT and the muon detector system AMIGA. Both of these extensions individually have a large potential to answer further questions for example concerning the high energy galactic cosmic ray component and the transition from galactic to extragalactic cosmic rays. )

  10. Trajectory Model Outputs Over Southern Africa

    Freiman, M.; Riphagen, H.

    2001-12-01

    Trajectories provide a useful and relatively simple method of analysing possible three-dimensional transportation paths of air, aerosols, trace gases and water vapour with time. Wind trajectories advect a large number of measurements, all made at different times, backward or forward in time from the point at which they were made using forecast (during the campaign) and analysed (after the campaign) wind fields. These fields change both spatially and temporally over time. A Lagrangian kinematic trajectory analysis is employed. The trajectory model was driven by two sets of data: forecast meteorological, real-time, 3-hourly input data during the SAFARI2000 campaign, and analysed meteorological, 6-hourly input wind data after the campaign. In both cases the resolution of the data over Southern Africa was 0.5 degrees. Five-point trajectory clusters (at 2.5 degree spacing) were run to and from Maun, Mongu, Middleburg, Windhoek, Springbok and Durban to roughly cover the whole Southern African region at multiple levels from the lower to the upper-troposphere. In total, 6163 trajectories were calculated using forecast data. The dominant transport modes during the Southern African Regional Science Initiative (SAFARI 2000) are direct westerly and recirculated transport (predominantly on a subcontinental scale). The frequencies at which these transport modes occur vary with height and location. The trajectory output data is useful first and foremost to observe the dominant circulation patterns over Southern Africa both spatially and temporally at different levels of the troposphere and at various scales of motion. Secondly, the data is useful for anyone wishing to examine the sources of monitored upper-air aerosols and / or trace gases, to discriminate, for instance, between oceanic, clean continental and polluted continental air masses contributing to the observed concentrations. Finally, the data can be used to explain elevated or declined concentrations downwind within specified times.

  11. Permanent GPS Geodetic Array in Southern California

    NASA Technical Reports Server (NTRS)

    Green, Cecil H.; Green, Ida M.

    1998-01-01

    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.

    2008-01-01

    In June 2008, heavy rain caused severe flooding across southern Wisconsin. The floods were aggravated by saturated soils that persisted from unusually wet antecedent conditions from a combination of floods in August 2007, more than 100 inches of snow in winter 2007-08, and moist conditions in spring 2008. The flooding caused immediate evacuations and road closures and prolonged, extensive damages and losses associated with agriculture, businesses, housing, public health and human needs, and infrastructure and transportation. Record gage heights and streamflows occurred at 21 U.S. Geological Survey streamgages across southern Wisconsin from June 7 to June 21. Peak-gage-height data, peak-streamflow data, and flood probabilities are tabulated for 32 USGS streamgages in southern Wisconsin. Peak-gage-height and peak-streamflow data also are tabulated for three ungaged locations. Extensive flooding along the Baraboo River, Kickapoo River, Crawfish River, and Rock River caused particularly severe damages in nine communities and their surrounding areas: Reedsburg, Rock Springs, La Farge, Gays Mills, Milford, Jefferson, Fort Atkinson, Janesville, and Beloit. Flood-peak inundation maps and water-surface profiles were generated for the nine communities in a geographic information system by combining flood high-water marks with available 1-10-meter resolution digital-elevation-model data. The high-water marks used in the maps were a combination of those surveyed during the June flood by communities, counties, and Federal agencies and hundreds of additional marks surveyed in August by the USGS. The flood maps and profiles outline the extent and depth of flooding through the communities and are being used in ongoing (as of November 2008) flood response and recovery efforts by local, county, State, and Federal agencies.

  18. Southern Ocean Response to NADW Changes

    NASA Technical Reports Server (NTRS)

    Rind, David; Schmidt, G.; Russell, G.; deMenocal, P.; Hansen, James E. (Technical Monitor)

    2000-01-01

    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,

  19. Late-glacial of southern South America

    NASA Astrophysics Data System (ADS)

    Heusser, C. J.

    Overall trends in late-glacial paleoenvironments of southern South America are interpretable from the pollen stratigraphy of radiocarbon dated sections of mires in Tierra del Fuego (55°S), the Chilotan archipelago (42-43°S), and the Chilean Lake District (39-41°S). In Tierra del Fuego, southern beech ( Nothofagus) and shrub and herb taxa (Gramineae, Empetrum, Acaena, Gunnera, Compositae and Cyperaceae) serve as indicators of the changing climate; in the Chilotan archipelago and in the Chilean Lake District, southern beech and other trees (species of Myrtaceae, Podocarpus, Prumnopitys, Pseudopanax and Weinmannia) suffice as indices of climatic change. Pollen records from each of these regions, although in need of greater dating control, indicate climatic sequences that are broadly similar. The records, however, are not regionally consistent in all aspects and differ in their indicator value with the implication of fossil beetle evidence. Attempts at correlation can be unsatisfactory at times and can stem inter alia from the different ecophysiological responses of both plants and beetles to environmental pressures. These differences, which affect the timing of reproduction and migration, may result in the variable occurrence of different species in the records. The broad implication of the pollen data is that following a glacial readvance culminating at about 15,000-14,500 BP, late-glacial climate was generally warmer during intervals before 13,000 and between 12,000 and 11,000 BP, and was cooler between 13,000 and 12,000 and from 11,000 to 10,000 BP.

  2. Spatial Organization of Decadal and Bidecadal Rainfall On Southern North America and Southern South America

    NASA Astrophysics Data System (ADS)

    Lucero, O. A.; Rodriguez, N. C.

    The spatial organization of decadal and bidecadal components (fluctuations) of annual rainfall is identified in this research for two regions: 1) southern South America, and 2) southern North America (conterminous USA, southeastern Canada and northern and central Mexico). Findings indicate that these decadal and bidecadal components have highly-coherent wave-like spatial organization. Two types of organization of decadal and bidecadal components of annual rainfall were identified: a train of propagating fluctuations, and quasi-standing fluctuations. For decadal components, such patterns alternate in time. A widespread change in the spatial organization of decadal com- ponents of annual rainfall took place simultaneously in both continents in 1932. The bidecadal component is organized as standing fluctuations in southern North Amer- ica, and as travelling fluctuations in southern South America. The spatial pattern of decadal fluctuations of annual rainfall has 12- and 13-year cycle; and the spatial pat- tern of bidecadal fluctuations has predominantly 21- and 22-year cycles.

    With the launch of the South African National Laser Centre, new programs will need to be defined. Medical, environmental and industrial laser applications must obviously take top priority -- as opposed to the uranium isotope separation and military applications of the past. We argue however, that a small effort in laser ablation for space propulsion is justifiable, since a few very large CO2 lasers are available and since two tentative propulsion experiments have already been conducted in South Africa. We attempt to give LISP (Laser Impulse Space Propulsion) an equatorial and a Southern dimension.

  6. Ethnobotanical remarks on Central and Southern Italy

    Guarrera, Paolo Maria; Lucia, Leporatti Maria

    2007-01-01

    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

  7. Detecting Ambient Tectonic Tremor in Southern California

    NASA Astrophysics Data System (ADS)

    Brown, J. R.; Hough, S. E.; Ampuero, J. P.

    2012-12-01

    In every tectonic setting where it is observed, tremor proves difficult to detect due to its long durations and low amplitudes close to the noise band. This is particularly true in southern California where cultural noise sources are both spatially and temporally pervasive. Ambient tectonic tremor in circum-Pacific subduction zones was shown to consist of repeating low-frequency earthquakes and locates at the deep extent of the primary seismogenic zone in a region downdip of historical M 8+ earthquakes. The signals were also shown to have a distinct spectral shape (typically around 1-8 Hz) whose higher frequency falloff differs from that of local noise and ordinary earthquakes. In the strike-slip setting, families of deep ambient tremors near the Parkfield-Cholame segment of the San Andreas fault were considered proxies for deep fault slip. Whether ambient tremor occurs in a similar fashion- or even at all- in southern California remains unclear. We employ a combination of running autocorrelation and matched-filter techniques successfully used in both subduction and strike slip settings to detect and locate tremor/low-frequency earthquakes in southern California. In our case, however, detections are accepted or rejected by calculating their spectral shapes to assure the signals are distinct from local noise sources and earthquakes. We scan continuous seismic recordings of the Southern California Seismic Network near the San Jacinto fault from 2008-2012 to detect tremor-like signals, distinguish their spectral shape from other sources, and subsequently locate it. We target this area on account of the abundance of seismic stations including borehole stations. Also, since tremor (2-8 Hz) was triggered by the passing surface waves of the 2002 M 7.9 Denali earthquake in vicinity of the San Jacinto fault we expect an ambient signal to occur in the same area with a similar spectral shape. The application of a spectral discriminator is particularly needed in this region, where previous analysis identified recurrent transients with a spectrum peaked between 3 and 4 Hz associated with heavy train traffic along the Coachella Valley.

  11. Holocene tephrostratigraphy of southern Chiloé Continental (Andean southern volcanic zone; ~43°S), Chile

    The eruptive history of the volcanoes in the southern part of the Andean Southern Volcanic Zone (42.5-45°S) is very poorly constrained: only several late Quaternary eruptions have been identified, mostly from study of sparse roadcuts [1]. In this study, we further constrain the Holocene explosive eruption history around 43°S by identifying and analysing tephra layers preserved in a ~3.25m long peat core from Cuesta Moraga [2], ~35km east of Yanteles volcano. Cryptotephra was extracted following the method of [3], in addition to macrotephra; owing to the vicinity of the sampling site to the tephra sources, cryptotephra was found throughout the core stratigraphy, but was sufficiently variable in concentration that discrete layers were identifiable and attributed to specific eruptions. Chemical analysis of the glass by electron microprobe shows that the tephra layers originate from a number of volcanoes in the region. This new tephrostratigraphy improves our knowledge of the important history of explosive volcanism in this area, potentially tying the tephrostratigraphies of surrounding areas (e.g., [4]) and allowing improved evaluation of regional volcanic risk.

  2. Observations of change in the Southern Ocean.

    PubMed

    Jacobs, Stan

    2006-07-15

    The Southern Ocean has been in a state of disequilibrium with its atmosphere and cryosphere during recent decades. Ocean station and drifting float observations have revealed rising temperatures in the upper 3000m. Salinity has declined in intermediate waters and more rapidly in the sparsely sampled high latitudes. Dissolved oxygen levels may also have decreased, but measurement accuracy is inconsistent. Sea ice area increased from 1979 to 1998, particularly in the Ross Sea, while a decline in ice extent since the early 1970s has been led by the Amundsen-Bellingshausen sector. Fresher waters with lower oxygen isotope content on the Pacific-Antarctic continental shelf are consistent with increased melting of continental ice. Newly forming bottom water has become colder and less salty downstream from that region, but generally warmer in the Weddell Sea. Many ice shelves have retreated or thinned, but others have grown and no trend is apparent in the large iceberg calving rate. Warming and isotherm shoaling within the polar gyres may result in part from changes in the Southern Annular Mode, which could facilitate deep-water access to the continental shelves. Sea-level rise over the past half century has a strong eustatic component and has recently accelerated. Observations over longer periods and with better spatial coverage are needed to better understand the processes causing these changes and their links to the Antarctic ice sheet. PMID:16782605

  3. SOAR + SMARTS Southern White Dwarf Survey

    NASA Astrophysics Data System (ADS)

    Subasavage, John P.; Lepine, S.

    2012-01-01

    We present early results from the SOAR + SMARTS Southern White Dwarf SURVEY (SSSWDS). Our initial sift of relatively bright (15 < V < 18), white dwarf candidates uses the technique of reduced proper motion with inputs from the SUPERBLINK proper motion database combined with photographic magnitudes. Crude distance estimates from the linear photographic magnitude-color relation of Oppenheimer et al. 2001 are obtained and permit prioritized follow-up. For confirmation of luminosity class, we use the SOAR telescope atop Cerro Pachon equipped with the Goodman Spectrograph and a moderate resolution grating. In tandem, we acquire multi-epoch, optical Johnson-Kron-Cousins BVRI photometry using the SMARTS 1.0m telescope atop CTIO. Combined with JHK from 2MASS, we compare the photometric SED to relevant white dwarf model atmospheres to estimate physical parameters (e.g., effective temperature, mass) and distance. For the nearest targets, specifically those within the RECONS (www.recons.org) horizon of 25 pc, we aim to obtain trigonometric parallaxes as part of the Cerro Tololo Inter-American Observatory Parallax Investigation (CTIOPI) project being conducted at the SMARTS 0.9m telescope. To date, we have confirmed 100 relatively bright, new white dwarfs in the southern hemisphere. Of those, 13 are estimated to be within our 25 pc horizon-of-interest, including two that are estimated to be within 15 pc. Ongoing observations will boost these figures by the end of the project.

  4. Nebular Abundances of Nearby Southern Dwarf Galaxies

    2003-01-24

    The results of optical spectroscopy of H II regions in a sample of southern dwarf irregulars consisting of five dwarf galaxies in the Centaurus A group, four dwarfs in the Sculptor group, and eight additional dwarf galaxies are presented. Oxygen abundances are derived using the direct method where [O III]4363 is detected; otherwise, abundances are derived with the bright-line method using the McGaugh and the Pilyugin calibrations. ESO358-G060 has the lowest oxygen abundance (12+log(O/H) = 7.32), which is comparable to the value for the second most metal-poor galaxy known (SBS0335-052). In all, new oxygen abundances are reported for nine dwarf galaxies; updated values are presented for the remaining galaxies. Derived oxygen abundances are in the range from 3% to 26% of the solar value. Oxygen abundances for dwarfs in the southern sample are consistent with the metallicity-luminosity relationship defined by a control sample of dwarf irregulars with [O III]4363 abundances and well-measured distances. However, NGC5264 appears to have an (upper branch) oxygen abundance approximately two to three times higher than other dwarfs at similar luminosities. Nitrogen-to-oxygen and neon-to-oxygen abundance ratios are also reported; in particular, IC1613 and IC5152 show elevated nitrogen-to-oxygen ratios for their oxygen abundances.

    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.

  6. Malaria epidemiology and control in Southern Africa.

    The burden of malaria has decreased dramatically within the past several years in parts of sub-Saharan Africa, following the scale-up of interventions supported by the Roll Back Malaria Partnership, the President's Malaria Initiative and other partners. It is important to appreciate that the reductions in malaria have not been uniform between and within countries, with some areas experiencing resurgence instead. Furthermore, while interventions have greatly reduced the burden of malaria in many countries, it is also recognized that the malaria decline pre-dated widespread intervention efforts, at least in some cases where data are available. This raises more questions as what other factors may have been contributing to the reduction in malaria transmission and to what extent. The International Center of Excellence for Malaria Research (ICEMR) in Southern Africa aims to better understand the underlying malaria epidemiology, vector ecology and parasite genomics using three contrasting settings of malaria transmission in Zambia and Zimbabwe: an area of successful malaria control, an area of resurgent malaria and an area where interventions have not been effective. The Southern Africa ICEMR will capitalize on the opportunity to investigate the complexities of malaria transmission while adapting to intervention and establish the evidence-base to guide effective and sustainable malaria intervention strategies. Key approaches to attain this goal for the region will include close collaboration with national malaria control programs and contribution to capacity building at the individual, institutional and national levels.

  9. Magma Piracy in the Southern Mariana Backarc

    NASA Astrophysics Data System (ADS)

    Becker, N. C.; Fryer, P.; Martinez, F.; Stern, R. J.; Bloomer, S. H.

    2001-12-01

    Since 1997 the southern Mariana convergent margin system has been mapped with Hydrosweep, MR-1, and SeaBeam swath sonar systems on five cruises resulting in 168,500 km2 of bathymetry data and 186,800 km2 of sidescan data, revealing anomalous processes relative to the rest of the Mariana region. Most of the Mariana Arc is characterized by arc volcanism dominated by large, central volcanoes located at the boundary between a backarc basin with slow-spreading ridge morphology and a nonaccretionary forearc composed of Eocene volcanic arc rocks But southwest of Tracey Seamount, the southernmost large central arc volcano, the character of the arc and backarc changes dramatically. The arc volcanoes become small or nonexistent, but those that do occur lie along relict spreading fabric within the backarc basin. Furthermore, the spreading center appears to have an inflated, fast-spreading morphology, including dueling propagator fabric, and this southern backarc basin forms a shallow plateau overall. The spreading center then becomes less well-defined west of 143oE, and the volcanism appears to cease altogether west of 142oE in an area of amagmatic rifting, an observation supported by earthquake focal mechanisms and magnetics. The inflated morphology of the spreading axis, along with the absence or reduced size of nearby arc volcanoes suggests that arc magmas have been entrained into the backarc-spreading magmatic system. This "magma piracy" would result in arc magma being erupted at the backarc spreading center, therefore the backarc crust would be formed in part from arc magmas. Dredge samples from along the active ridge show compositions consistent with this suggestion. We suggest that this magma piracy has dominated the southern backarc basin for at least the last 3 m.y. since the robust spreading began. We suggest that the apparently higher magma production rate and the hybridized crust could account for the shallowness of the basin, as the more evolved arc-lavas would be generally more buoyant than backarc basin basalt alone.

  10. Evaluation of network RTK in southern Ontario

    NASA Astrophysics Data System (ADS)

    Saeidi, Amir

    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.

    Ciguatera fish poisoning results from the bioconcentration of a variety of toxins produced by marine dinoflagellates. Signs and symptoms vary widely, but it usually presents as gastrointestinal and neurologic complaints beginning shortly after the ingestion of fish containing the toxins. Symptoms may persist for months and sometimes even years. Although cases have been reported throughout the United States, epidemics are most common along tropical and subtropical coasts and usually involve the ingestion of large carnivorous fish. We review the literature and report the first epidemic of 25 cases of ciguatera fish poisoning presenting to area hospitals in Southern California that were successfully tracked by the Department of Health Services and isolated to fish caught off the coast of Baja California, Mexico.

    Equine epizootics of Venezuelan equine encephalitis (VEE) occurred in the southern Mexican states of Chiapas in 1993 and Oaxaca in 1996. To assess the impact of continuing circulation of VEE virus (VEEV) on human and animal populations, serologic and viral isolation studies were conducted in 2000 to 2001 in Chiapas State. Human serosurveys and risk analyses indicated that long-term endemic transmission of VEEV occurred among villages with seroprevalence levels of 18% to 75% and that medical personnel had a high risk for VEEV exposure. Seroprevalence in wild animals suggested cotton rats as possible reservoir hosts in the region. Virus isolations from sentinel animals and genetic characterizations of these strains indicated continuing circulation of a subtype IE genotype, which was isolated from equines during the recent VEE outbreaks. These data indicate long-term enzootic and endemic VEEV circulation in the region and continued risk for disease in equines and humans. PMID:15663847

    The Southern Indus basin extends approximately between lat. 23/sup 0/ and 28/sup 0/31'N, and from long. 66/sup 0/E to the eastern boundary of Pakistan. Of the 55 exploratory wells drilled (1955-1984), 27 were based on results of multifold seismic surveys. Five commercial oil discoveries and one gas discovery in Cretaceous sands, three gas discoveries in Paleocene limestone or sandstone, and one gas-condensate discovery from lower Eocene limestone prove that hydrocarbons are present. The main hydrocarbon fairways are Mesozoic tilted fault blocks. Tertiary reefal banks, and drape and compressional anticlines. Older reservoirs are accessible toward the east and northeast, and younger mature source rocks are to the west, including offshore, of the Badin block oil field area. The Indus offshore basin reflects sedimentation associated with Mesozoic rifting of the Pakistan-Indian margin, superimposed by a terrigenous clastic depositional system comprised of deltas, shelves, and deep-sea fans of the Indus River.

    An improved understanding of heterogeneities in dengue virus transmission might provide insights into biological and ecologic drivers and facilitate predictions of the magnitude, timing, and location of future dengue epidemics. To investigate dengue dynamics in urban Ho Chi Minh City and neighboring rural provinces in Vietnam, we analyzed a 10-year monthly time series of dengue surveillance data from southern Vietnam. The per capita incidence of dengue was lower in Ho Chi Minh City than in most rural provinces; annual epidemics occurred 1–3 months later in Ho Chi Minh City than elsewhere. The timing and the magnitude of annual epidemics were significantly more correlated in nearby districts than in remote districts, suggesting that local biological and ecologic drivers operate at a scale of 50–100 km. Dengue incidence during the dry season accounted for 63% of variability in epidemic magnitude. These findings can aid the targeting of vector-control interventions and the planning for dengue vaccine implementation. PMID:23735713

    The southern Pierre Auger Observatory has been detecting cosmic rays above 1018eV since 2004, exploiting a hybrid air shower detection technique, with 1660 water Cherenkov detectors together with 24 air fluorescence telescopes on a 3000 km2 site. As low energy enhancements to the observatory, 3 additional telescopes with elevated fields of view were built (HEAT). The detector density was increased in the HEAT fields of view by a factor of four in an area of about 25 km2. This setup enables unbiased hybrid data taking above 1017eV. The infilled area is also being equipped with large underground scintillator muon detectors (AMIGA). Finally, a prototype array of radio antenna stations (AERA), working from 30 to 80 MHz, has been installed in a part of the infill. Properties and status of AMIGA, HEAT, and AERA are presented.

    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.

  1. Brazil to Join the European Southern Observatory

    NASA Astrophysics Data System (ADS)

    2010-12-01

    The Federative Republic of Brazil has yesterday signed the formal accession agreement paving the way for it to become a Member State of the European Southern Observatory (ESO). Following government ratification Brazil will become the fifteenth Member State and the first from outside Europe. On 29 December 2010, at a ceremony in Brasilia, the Brazilian Minister of Science and Technology, Sergio Machado Rezende and the ESO Director General, Tim de Zeeuw signed the formal accession agreement aiming to make Brazil a Member State of the European Southern Observatory. Brazil will become the fifteen Member State and the first from outside Europe. Since the agreement means accession to an international convention, the agreement must now be submitted to the Brazilian Parliament for ratification [1]. The signing of the agreement followed the unanimous approval by the ESO Council during an extraordinary meeting on 21 December 2010. "Joining ESO will give new impetus to the development of science, technology and innovation in Brazil as part of the considerable efforts our government is making to keep the country advancing in these strategic areas," says Rezende. The European Southern Observatory has a long history of successful involvement with South America, ever since Chile was selected as the best site for its observatories in 1963. Until now, however, no non-European country has joined ESO as a Member State. "The membership of Brazil will give the vibrant Brazilian astronomical community full access to the most productive observatory in the world and open up opportunities for Brazilian high-tech industry to contribute to the European Extremely Large Telescope project. It will also bring new resources and skills to the organisation at the right time for them to make a major contribution to this exciting project," adds ESO Director General, Tim de Zeeuw. The European Extremely Large Telescope (E-ELT) telescope design phase was recently completed and a major review was conducted where every aspect of this large project was scrutinised by an international panel of independent experts. The panel found that the E-ELT project is technically ready to enter the construction phase. The go-ahead for E-ELT construction is planned for 2011 and when operations start early in the next decade, European, Brazilian and Chilean astronomers will have access to this giant telescope. The president of ESO's governing body, the Council, Laurent Vigroux, concludes: "Astronomers in Brazil will benefit from collaborating with European colleagues, and naturally from having observing time at ESO's world-class observatories at La Silla and Paranal, as well as on ALMA, which ESO is constructing with its international partners." Notes [1] After ratification of Brazil's membership, the ESO Member States will be Austria, Belgium, Brazil, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom. More information ESO, the European Southern Observatory, is the foremost intergovernmental astronomy organisation in Europe and the world's most productive astronomical observatory. It is supported by 14 countries: Austria, Belgium, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries. ESO also plays a leading role in promoting and organising cooperation in astronomical research. ESO operates three unique world-class observing sites in Chile: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope, the world's most advanced visible-light astronomical observatory and VISTA, the world's largest survey telescope. ESO is the European partner of a revolutionary astronomical telescope ALMA, the largest astronomical project in existence. ESO is currently planning

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

    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.

  3. Tectonic Rotations in the Southern Central Andes

    NASA Astrophysics Data System (ADS)

    Arriagada, C.; Mpodozis, C.; Roperch, P.

    2007-05-01

    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.

  4. Potential Dust Emissions from Sources in the Southern Hemisphere.

    NASA Astrophysics Data System (ADS)

    Bhattachan, A.; D'Odorico, P.; Okin, G. S.

    2014-12-01

    The Southern Hemisphere currently exhibits low levels of atmospheric dust concentrations relative to the Northern Hemisphere. Recent research suggests that dust concentrations could, however, increase as a result of loss of vegetation cover in the Southern Kalahari and the Mallee. Disturbances resulting from grazing and agriculture are identified as such drivers of land use change in these regions. While studies on the importance of atmospheric dust in global-scale processes are abundant, little has been done to locate the potential dust sources in the Southern Hemisphere because potential new sources are by definition inactive and are undetected in satellite images. To this end, using a combination of laboratory experiments and field observations, we assess that the sediments collected from the dunefields in the Southern Kalahari and Mallee can emit substantial amount of dust, are rich in soluble iron and dust from these sources would reach the Southern Ocean. It is suggested that the supply of soluble iron through atmospheric dust deposition limits the productivity of the Southern Ocean. Thus intensification of land use can potentially make these regions an important source of iron given their proximity to the Southern Ocean. This iron-rich dust could stimulate ocean productivity in future as more areas are reactivated as a result of land-use and droughts.

    Observations in the southern galactic hemisphere in the declination range between -17.5 and 2.5 degrees are combined with other available observation. The data set is used to study the spatial distribution of galaxies of a contiguous area of 3.13 sr of the Southern Galactic Cap. An approximately homogeneous magnitude-limited sample of galaxies in the Southern Galactic Cap is constructed from different catalogs. The resulting large scale structure is similar to that of previous surveys in which bright galaxies are distributed on surfaces which intersect at sharp corners and nearly surround voids that are almost empty of galaxies. 29 refs.

    .3 The Southern Ocean in models The Southern Ocean has been represented in models with a range of complexities, from full Earth system models to simple 2D quasi-geostrophic models to 1D flux models. Due to computational restrictions, modern global circulation... models and earth system models are eddy-permitting, rather than eddy-resolving. This requires some parametrisation of eddy activity, as previously mentioned. Lee and Coward (2003) studied the Southern Ocean in the OCCAM model at 1/4? (eddy permitting...

  7. The last glacial-Holocene transition in southern Chile.

    Bennett, K D; Haberle, S G; Lumley, S H

    2000-10-13

    Warming at the last glacial termination in the North Atlantic region was interrupted by a period of renewed glacial activity during the Younger Dryas chronozone (YDC). The underlying mechanism of this cooling remains elusive, but hypotheses turn on whether it was a global or a North Atlantic phenomenon. Chronological, sedimentological, and palaeoecological records from sediments of small lakes in oceanic southern Chile demonstrate that there was no YDC cooling in southern Chile. It is therefore likely that there was little or no cooling in southern Pacific surface waters and hence that YDC cooling in the North Atlantic was a regional, rather than global, phenomenon.

  10. Early holocene openlands in southern New England.

    The pre-historical vegetation structure in temperate forest regions is much debated among European and North American ecologists and conservationists. Frans Vera's recent hypothesis that large mammals created mosaics of forest and openland vegetation in both regions throughout the Holocene has been particularly controversial and has provoked new approaches to conservation management. Thirty years earlier, American paleoecologists Herb Wright and Margaret Davis debated whether abundant ragweed pollen at Rogers Lake, Connecticut at 9500 yr BP signified local forest openings or long-distance transport of pollen from Midwestern prairies. Using new pollen records from Harvard Forest and the North American Pollen Database, we address this question and offer insights to the openland discussion. Ragweed and other forbs exceed 3.5% at five sites in a restricted area of southern New England between 10,100 and 7700 yr BP. Strong evidence suggests this pollen originated from the landscapes surrounding these sites (supporting Davis), as ragweed pollen percentages do not increase with longitude from New England to the Midwest. Ragweed pollen percentages are also unrelated to basin size and therefore unrelated to the proportion of extraregional pollen in New England. High forbs values were associated with increases in oak, decreases in white pine, and relatively high charcoal values. Modern pollen records with similar forb and tree percentages occur along the Prairie Peninsula region of the Upper Midwest. However, the closest analogue to the southern New England early Holocene assemblages comes from Massachusetts' Walden Pond in the early 18th century. These results and the affiliation of ragweed for open, disturbed habitats suggest that oak-pine forests with large openings persisted for over 2000 years due to dry conditions and perhaps increased fire frequency. This conclusion is corroborated by independent lake level and climate reconstructions. Because these early Holocene openlands have no detectable analogue in New England for the past 7000 years before European settlement, we suggest that all important openlands today are almost exclusively a legacy of Colonial agriculture and should be managed accordingly. Nonetheless, our results may have implications for forest dynamics accompanying projected climate change to more arid conditions in New England over the next century. PMID:17089662

    The founding and early development of the Southern Pediatric Neurology Society was in many ways parallel to that of the Child Neurology Society. The organization started out as the Southern Child Neurology Society but the name was changed at the time of incorporation so as to avoid confusion of identity and purpose with the larger Child Neurology Society. Although there are archives of early days and the later development of the Southern Pediatric Neurology Society, the details have never been set down in a narrative explaining the events that led to the development of the organization. In this paper, we try to produce a written record of the history of the founding and early development of the Southern Pediatric Neurology Society. PMID:24646505

  20. The Southern Cone: A critical element in North American geology

    SciTech Connect

    Dalziel, I.W.D. (Univ. of Texas, Austin, TX (United States). Inst. for Geophysics)

    1993-02-01

    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.

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

    NASA Astrophysics Data System (ADS)

    Minear, J. T.; Kondolf, G. M.

    2003-12-01

    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.

    Inhomogeneous networks and reference frames are an important issue for Very Long Baseline Interferometry (VLBI). In this work we examine the performance of southern stations and baselines in routine VLBI experiments. A positive impact on baseline length repeatabilities of the increased observing effort by the Australian AuScope VLBI antennas is found by analysing three years of global rapid-turnaround VLBI sessions: while worse results are found for southern baselines compared to northern baselines for the first half of the investigated sessions, the northern and southern baseline length repeatabilities are about the same in the second half of the period. In simulations, the actual observing plan with a significantly lower number of observations for southern stations is identified as a major reason for the worse length WRMS for southern baselines, though other factors seem to influence the results as well. Simulating radio source position uncertainties, effects of up to 10 mm are found on baseline length WRMS for long southern baselines. Improving all source position uncertainties through more frequent observations to better than 50 ? as could reduce this effect by up to 30 % .

    Several massive wildfires were raging across southern California over the weekend of October 25, 2003. Whipped by the hot, dry Santa Ana winds that blow toward the coast from interior deserts, at least one fire grew 10,000 acres in just 6 hours. Moving northwest to southeast along the coast, the first cluster of red dots is a combination of the Piru, Verdale, and the Simi Incident Fires; The next cluster-to the east of Los Angeles-is the Grand Prix (west) and Old (east) Fires; To their south is the Roblar 2 Fire; Next is the Paradise Fire; Then the massive Cedar Fire, whose thick smoke is completely overshadowing the coastal city of San Diego; Finally, at the California-Mexico border is the Otay Fire. At least 13 people have lost their lives because of these fires, which officials are reporting were caused by carelessness and arson. Thousands have been evacuated across the region and hundreds of homes have been lost.

  6. Absolute Proper Motions of Southern Globular Clusters

    Our program involves the determination of absolute proper motions with respect to galaxies for a sample of globular clusters situated in the southern sky. The plates cover a 6(deg) x 6(deg) area and are taken with the 51-cm double astrograph at Cesco Observatory in El Leoncito, Argentina. We have developed special methods to deal with the modelling error of the plate transformation and we correct for magnitude equation using the cluster stars. This careful astrometric treatment leads to accuracies of from 0.5 to 1.0 mas/yr for the absolute proper motion of each cluster, depending primarily on the number of measurable cluster stars which in turn is related to the cluster's distance. Space velocities are then derived which, in association with metallicities, provide key information for the formation scenario of the Galaxy, i.e. accretion and/or dissipational collapse. Here we present results for NGC 1851, NGC 6752, NGC 6584, NGC 6362 and NGC 288.

  7. Helminths of the ocelot from southern Texas.

    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.

    Fawcett, J.H.

    1987-01-01

    This dissertation is in the field of environmental economics and is about institutional change. Chapter 1 sets up a contrast between utilitarian and functionalist thinking on institutional change. Functionalist theory is shown to go usefully beyond utilitarian theory in explaining the outcome of institutional operation and change. Chapter 2 introduces the politics of air pollution control along with a supply-demand model to represent utilitarian theory. Chapter 3 provides a brief history of air pollution control in Southern California that is couched in terms of the supply and demand for clean air. In chapter 4 the rational is for using visibility reduction as the measure of air quality is given along with the basic trends in this indicator; results show a general improvement in air quality. In chapter 5 the concept of structural change is introduced. The regulation of the automobile is heavily implicated. In chapter 6, the air-quality trends are controlled for basic causal factors. Chapter 7 concludes that the changes predicted by the utilitarian model do not occur, while the results are consistent with the functionalist model.

    Interpretation of regional seismic data acquired in the 1990s together with a re-appraisal of the wells drilled in the 1970s has lead to an appreciation that the southern West Greenland Basin is underexplored and may contain large quantities of hydrocarbons. The regional structure and stratigraphy of the basin has been worked out. An early phase of extension, probably in the Early Cretaceous, was followed by a thermal subsidence phase in the Late Cretaceous during which thick mudstones were deposited. Renewed extension and strike-slip faulting associated with the onset of sea-floor spreading in the Labrador Sea in the Early Tertiary lead to the formation of large structures capable of trapping large quantities of hydrocarbons. Flat spots have been identified in several prospects in the Fylla Structural Complex, which is presently open for licensing, and other large structural traps exist on the Kang{cflx a}miut Ridge and in the Ikermiut area. Stratigraphic traps exist in a large syn-rift fan of mid-Cretaceous age and in Lower Tertiary basin-floor fans.

    2007-01-01

    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.

    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.

  16. Carboniferous sedimentation and tectonics in southern Morocco

    The Carboniferous rocks of southern Morocco record the gradual change from the extensional tectonic style of the early Paleozoic to a compressional regime. During the Tournaisian and early Visean, northwest compression formed a rising anticline in the Anti-Atlas, which provided sediments to shallow marine basins formed in the flanking synclines. During the late Visean, tectonic activity increased markedly, and northward-downthrowing normal/oblique slip faulting formed submarine fault scarps. Turbidity currents and debris flows together with giant exotic blocks were shed northward from these scarps. The turbidity currents were deflected eastward to flow down the axes of these small easterly plunging marine basins. A late Visean phase of minor folding with locally developed cleavage and quartz veining closed these basins. The folded sequences are unconformably overlain by uppermost Visean fluvial sediments deposited from northward and eastward-flowing rivers. During the Pennsylvanian, collisional tectonics recorded in the Moroccan Meseta to the north were probably responsible for thrust faulting and the formation of a high-angle cleavage. Thick (up to 4.5 km) sandstones and conglomerates with red mudstones, paleosols, and coals are preserved on the fringes of the area. These were deposited by southeast-flowing rivers and are interpreted as the eroded remnants of a syn-postorogenic molasse deposited in a major foredeep south of the main orogen.

    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.

    Surrounded by the Benue trough, the Middle Niger River depression, the Niger River delta, and the Abakaliki anticlinorium, Nigeria's Anambra basin probably holds a thick, unexplored sequence with significant hydrocarbon potential. The basin's sediment could be 16,000 ft thick; a Bouguer gravity survey indicates two parallel northeast-southwest trending gravity lows (the Anambra low and the Awka depression) separated by the Onitsha high. Although geologists interpret the basin as Upper Cretaceous-Lower Tertiary, its southern portion is down-warped and overlapped by the delta's thick Tertiary deposits, lowering the Cretaceous to prohibitive depths in the overlap areas; wells drilled to 16,000 ft at the delta's apex thus have not encountered the Cretaceous sediments. An evaluation of the basin's pre-Santonian hydrocarbon prospects will require a deep exploratory drilling program. As Nigeria shifts its production emphasis from oil to gas and firms up plans for an LNG plant in the Niger delta, exploration in the gas-prone Anambra basin will probably surge.

    From a regional inventory of monthly droughts, which was evaluated in six regions of southern South America, the seasonal occurrence of the phenomenon and its persistence together with the duration of monthly and annual sequences, extreme events, and other statistical estimates of the proposed index have been studied. In a primary analysis, it is possible to observe that regions present different behaviors regarding the duration of dry sequences, with more persistence in the Argentinean continental region. Temporal behaviors of the annual indexes have also been analyzed, in the attempt to determine any aspects of the impact of global warming. Through this analysis, the presence of long favorable tendencies regarding precipitations or the inverse of droughts occurrence are confirmed for the eastern Andes Mountains in Argentina (ARG) with its five sub-regions (Northwest Argentina-NWA, Northeast Argentina-NEA, Humid Pampa-HP, West-Centre Provinces-WC and Patagonia-PAT, and the inverse over the central region of Chile (CHI). Other climatic great-scale changes are interdecadales variations and variances explained according to ENSO.

    Presented in this report is a summary of the major structures and seismotectonic zones in Southern Africa (Botswana, Lesotho, Namibia, South Africa and Swaziland), which includes available information on fault plane solutions and stress data. Reports published by several experts contributed much to the prepared zones. The work was prepared as part of the requirements for the SIDA/IGCP Project 601 titled "Seismotectonics and Seismic Hazards in Africa" as well as part of the seismic source characterisation of the GEM-Africa Seismic hazard study. The seismic data used are part of the earthquake catalogue being prepared for the GEM-Africa project, which includes historical and instrumental records as collected from various agencies. Seventeen seismic zones/sources were identified and demarcated using all the available information. Two of the identiied sources are faults with reliable evidence of their activity. Though more faults have been identified in unpublished material as being active, more work is being carried out to obtain information that can be used to characterise them before they are included in the seismotectonic model. Explanations for the selected boundaries of the zones are also given in the report. It should be noted that this information is the first draft of the seismic source zones of the region. Futher interpreation of the data is envisaged which might result in more than one version of the zones.

    Southern spring on Mars began with a 'bang' in late June 2001 with a series of large dust storms that in some regions were still occurring each day well into September. By early July, the martian atmosphere was so hazy that opportunities for high resolution imaging of the planet were very limited. This wide angle camera view obtained by the Mars Global Surveyor Mars Orbiter Camera shows a large dust-raising event that occurred on July 8, 2001, as cold, raging winds blew off the frozen south polar cap (bottom) and rushed toward the network of troughs known as Labyrinthus Noctis near the martian equator (center). A second, smaller dust storm can be seen near the top just left of center, northwest of the Ascraeus Mons volcano (uppermost dark elliptical feature). To give a sense of scale, Ascraeus Mons is large enough to nearly cover the state of Washington, home of the famous (and much smaller) Mount St. Helens volcano. Sunlight illuminates the scene from the left, and north is toward the upper right.

    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.

    Whilst we have now a good understanding how past glaciation influenced species at the northern hemisphere, our knowledge of patterns and modes of speciation is far more limited for the southern hemisphere. We provide mtDNA based data on the phylogeography of a circumpolar distributed southern hemisphere seabird group-the southern skua complex (Catharacta spp.). Diversification of southern skuas dates between 210,000 yBP and 150,000 yBP and coincides with a glacial spanning 230,000-140,000 yBP. Skuas most likely first inhabited the Antarctic continent, in the course of global cooling and increasing glaciation spread to the sub-antarctic islands and Tristan da Cunha and finally colonized Patagonia and the Falkland Islands at the glacial maximum. Despite significant differences between taxa most populations still exchange genes with neighboring populations of other taxa and speciation is incomplete. PMID:18706509

  7. Characteristics of Southern California coastal aquifer systems

    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.

  8. Southern California Shaded Relief, Color as Height

    From the desert to the mountains to the sea,' this image shows in striking detail the varied topography of Southern California. The data, which cover an area one and a half times the size of New Jersey, were acquired in 15 seconds by the Shuttle Radar Topography Mission (SRTM). The large V-shape across the center of the image is the intersection of the mountains uplifted along two major faults. The San Andreas Fault is the lower part of the 'V' and the Garlock Fault is the upper part. Between the faults is the western Mojave Desert, including the alternate landing site for the Shuttle at Edwards Air Force Base, near the center of the image. The Pacific Coast appears in the lower left of the image, from Oxnard at the left center edge, curving southeast to Los Angeles. The flat blue area along the top is the southern end of California's Central Valley. Along the right edge of the image is NASA's Goldstone Deep Space Tracking Station. Scientists will use data like these to study a broad range of topics, including ecology, the environment, geology, as well as to make assessments of seismic, flood, and wildfire hazards.

    This shaded relief image was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. Colors show the elevation as measured by SRTM. Colors range from blue at the lowest elevations to white at the highest elevations. This image contains about 3000 meters (10,000 feet) of total relief. White speckles on the face of some of the mountains are holes in the data caused by steep terrain. These will be filled using coverage from an intersecting pass.

    The Shuttle Radar Topography Mission (SRTM), launched on February 11,2000, uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. The mission is designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, an additional C-band imaging antenna and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) and the German (DLR) and Italian (ASI) space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise, Washington, DC.

    As understanding of the complex relations among environmental stressors and biological responses improves, a logical next step is predictive modeling of biological condition at unsampled sites. We developed a boosted regression tree (BRT) model of biological condition, as measured by a benthic macroinvertebrate index of biotic integrity (BIBI), for streams in urbanized Southern Coastal California. We also developed a multiple linear regression (MLR) model as a benchmark for comparison with the BRT model. The BRT model explained 66% of the variance in B-IBI, identifying watershed population density and combined percentage agricultural and urban land cover in the riparian buffer as the most important predictors of B-IBI, but with watershed mean precipitation and watershed density of manmade channels also important. The MLR model explained 48% of the variance in B-IBI and included watershed population density and combined percentage agricultural and urban land cover in the riparian buffer. For a verification data set, the BRT model correctly classified 75% of impaired sites (B-IBI < 40) and 78% of unimpaired sites (B-IBI = 40). For the same verification data set, the MLR model correctly classified 69% of impaired sites and 87% of unimpaired sites. The BRT model should not be used to predict B-IBI for specific sites; however, the model can be useful for general applications such as identifying and prioritizing regions for monitoring, remediation or preservation, stratifying new bioassessments according to anticipated biological condition, or assessing the potential for change in stream biological condition based on anticipated changes in population density and development in stream buffers.

  10. Hydrated Minerals in the Martian Southern Highlands

    Hydrated minerals including sulfates, phyllosilicates, and hydrated silica have been observed on the surface of Mars by the orbital near-infrared spectrometers OMEGA and CRISM [1,2]. Global maps from OMEGA [3,4] show that km-scale and larger exposures of these minerals are scattered widely throughout the planet's low and mid latitudes, but are relatively rare. Yet CRISM has found hundreds to thousands of Fe/Mg-phyllosilicate exposures in the highlands of Terra Tyrrhena alone [2], suggesting that smaller exposures may be much more common. To search for such exposures, we have surveyed the browse products from all PDS-released CRISM targeted observations (as of July 2008) across a large fraction of the Southern highlands, including the Noachis, Cimmeria, and Sirenum regions. Sulfates are observed in Noachian-aged terrains in each of these regions, including as far South as -63º latitude, suggesting that sulfate formation may have occurred locally or regionally throughout a large fraction of Martian history. Some of our strongest phyllosilicate detections occur adjacent to inferred chloride-bearing deposits [5] in Terra Sirenum. Also in Sirenum, the D 100 km Columbus crater contains light-toned, hydrated sulfate-bearing layers overlying materials that contain both a kaolin group clay and Fe/Mg-smectite clay, in different locations. However, phyllosilicates do not appear predominantly associated with impact craters in the regions surveyed, in contrast with Terra Tyrrhena [2]. We are currently searching for additional hydrated mineral exposures using CRISM multispectral data, providing further detail on their global distribution and identifying local areas of interest for future focused studies.

    This work presents results of the Joint Project for Solar UV Index Measurements in Southern Bahia State (PIU Project), and represents the first effort to measure UV radiation in this tourist region. The project goal is twofold: it has a scientific component in which the distribution of UV Index will be mapped out, and it also intends to disseminate the data as a mean of divulgation of the UV Index levels to the population. This constitutes a meaningful effort to reduce health risks from excessive solar radiation exposure in a country that reports more than 120,000 new skin cancer cases each year. This project is within the framework of a larger initiative to studying UV index distribution in Brazilian regions. PIU project has had two phases: 1) seasonal measurements were performed during the summer and winter seasons of 2006 and 2007 on a sandy beach in Ilhéus (15,0° S; 39,0° W; sea level), as well as on an asphalt surface in the urban perimeter of Itabuna (14,8° S; 39,3° W; 54 m ASL); and 2) since October 2007, measurements have been continuously conducted on a concrete surface, about 20 km from the beach, in a urban area of Ilhéus. During the summer season, UV Index reaches extreme values (>11), and in winter, results range between high (6

    Current evidence of phenological responses to recent climate change is substantially biased towards northern hemisphere temperate regions. Given regional differences in climate change, shifts in phenology will not be uniform across the globe, and conclusions drawn from temperate systems in the northern hemisphere might not be applicable to other regions on the planet. We conduct the largest meta-analysis to date of phenological drivers and trends among southern hemisphere species, assessing 1208 long-term datasets from 89 studies on 347 species. Data were mostly from Australasia (Australia and New Zealand), South America and the Antarctic/subantarctic, and focused primarily on plants and birds. This meta-analysis shows an advance in the timing of spring events (with a strong Australian data bias), although substantial differences in trends were apparent among taxonomic groups and regions. When only statistically significant trends were considered, 82% of terrestrial datasets and 42% of marine datasets demonstrated an advance in phenology. Temperature was most frequently identified as the primary driver of phenological changes; however, in many studies it was the only climate variable considered. When precipitation was examined, it often played a key role but, in contrast with temperature, the direction of phenological shifts in response to precipitation variation was difficult to predict a priori. We discuss how phenological information can inform the adaptive capacity of species, their resilience, and constraints on autonomous adaptation. We also highlight serious weaknesses in past and current data collection and analyses at large regional scales (with very few studies in the tropics or from Africa) and dramatic taxonomic biases. If accurate predictions regarding the general effects of climate change on the biology of organisms are to be made, data collection policies focussing on targeting data-deficient regions and taxa need to be financially and logistically supported.

    To study the levels and distributions of radionuclides released in the Chernobyl accident, we sampled surface peat from 62 sites in Southern and Central Finland and measured 131I, 134Cs, 137Cs, 132Te, 140Ba, 103Ru, 90Sr, 141Ce, and 95Zr. The distribution of fallout activities was highly uneven, depending on movement of the contaminated air mass and rainfall distribution during the critical days. The highest values observed were 420 kBq m-2 of 131I and 70 kBq m-2 of 137Cs. The nuclide ratios showed wide and partly unexpected variations. The high-boiling-point, or nonvolatile, elements Ce and Zr were spread mostly on a 200-km-wide zone extending across Finland from southwest to northeast. The more volatile elements, I, Ce, and Te, showed quite a different, more widespread, fallout distribution, while an intermediate behavior was observed for Ba, Ru, and possibly Sr. These results can be explained by assuming that pulverized nuclear fuel material released in the reactor explosion on 26 April reached Finland via Poland and the Baltic Sea and traversed the country along the above-mentioned narrow zone, while volatile material, evaporated in the reactor fire from 26 April to 5 May, arrived in several waves and was consequently more widely and evenly spread. From their elemental melting and boiling points, Ru and Mo would appear to belong to the nonvolatile group and Sr to the volatile. Yet, their actual behaviors were opposite; Ru in particular was found in the nonvolatile as well as the volatile fallout, possibly because Ru activities were present in the fuel partly in the metallic state and partly as volatile oxides.

  14. Jurassic hydrocarbon exploration of southern Florida

    South Florida Jurassic exploration has been overlooked as a viable exploration target due to lack of data and plate-tectonics application. In Florida, {open_quotes}basement{close_quotes} is defined as crystalline, igneous, metamorphic, and unmetamorphosed sediments of Paleozoic age. Age-dating of zircons has proven that the Florida lower Paleozoic terrane is not akin to that of North America but is part of the West African Guinean shield. Previous published reconstructions of late Paleozoic fits of crustal plates and continents have failed to account for the differences in peninsula Florida basement and the geologic and tectonic continuities of peninsula Florida, Yucatan, Cuba, Hispaniola, and Bahamas. Pre-Atlantic reconstruction of the Gulf of Mexico in this study proposes that there was a Florida connection to Yucatan-Cuba-Africa during the Triassic. This reconstruction also shows that the Jurassic sediments that are well known in the northern Gulf Coast should have been deposited in similar depositional environments in southern Florida. Deep drilling on the Florida peninsula has confirmed this hypothesis. By using plate tectonic reconstruction based on the rising of the North Atlantic Ocean and evidence from petrology of basement samples from deep wells together with petrographic analyses of Jurassic sediments, a Smackover-equivalent exploration play can be developed. Petrographic and petrophysical analysis of these wells that have encountered Jurassic marine shales, anhydrite, dolomite, carbonate, and elastic sediments has determined that these sediments are from shallow-water subtidal, tidal, intertidal, and supratidal environments. Excellent gas shows, oil stain in the pores and high TOC values in the marine shales, indicate that large accumulations of hydrocarbon are present.

  16. Transport of Biomass Burning Emissions from Southern Africa

    The transport of biomass burning emissions from southern Africa to the neighboring Atlantic and Indian Oceans during the dry season (May-October) of 2000 is characterized using ground, ozonesonde, and aircraft measurements of carbon monoxide (CO) and ozone (O3) in and around southern Africa, together with the GEOS-CHEM global model of tropospheric chemistry. The model shows a positive bias of approximately 20% for CO and a negative bias of approximately 10-25% for O3 at oceanic sites downwind of fire emissions. Near areas of active fire emissions the model shows a negative bias of approximately 60% and approximately 30% for CO and O3, respectively, likely due to the coarse spatial (2 deg. x 2.5 deg.) and temporal (monthly) resolution of the model compared to that of active fires. On average, from 1994 to 2000, approximately 60 Tg of carbon monoxide (CO) from biomass burning in southern Africa was transported eastward to the Indian Ocean across the latitude band 0 deg. -60 S during the 6 months of the dry season. Over the same time period, approximately 40 Tg of CO from southern African biomass burning was transported westward to the Atlantic Ocean over the latitudes 0 deg. -20 S during the 6-month dry season, but most of that amount was transported back eastward over higher latitudes to the south (21 deg. -60 S). Eastward transport of biomass burning emissions from southern Africa enhances CO concentrations by approximately 4- 13 ppbv per month over the southern subtropical Indian Ocean during the dry season, with peak enhancements in September. Carbon monoxide from southern African and South American biomass burning is seen in the model simulations as far away as Australia, contributing approximately 8 ppbv and approximately 12-15 ppbv CO, respectively, and thus explaining the approximately 20- 25 ppbv observed enhancement of CO over Melbourne in mid-September 2000.

  17. Public water supplies in southern Texas

    This report gives a summarized description of the public water supplies in 42 counties of southern Texas, extending from the Rio Grande northward to the northern boundaries of Kinney, Uvalde, Bandera, Kendall, and Hays Counties and eastward to the eastern boundaries of Caldwell, Gonzales, De Witt, Victoria, and Calhoun Counties. It gives the available data as follows for each of the 114 communities: Population of the community; name of the official from whom the information was obtained; ownership of water works, whether private or municipal; source of supply, whether ground or surface water; the amount of water consumed; the facilities for storage; the number of customers served; the character of the chemical and sanitary treatment, if any; and chemical analyses of the water. Where ground water is used, the following information also is given: Records of wells, including drillers' logs; character of the pumping equipment; yield of the wells and records of water levels, where they are available. The communities served by these public supplies had a population of 668,000 in 1940. Ground water is used by 79 of these communities and surface water by 31. The total amount of water consumed averages about 95 million gallons a day, of which about 55 million gallons is obtained from ground water and about 40 million gallons from surface water. The extreme northern part of the region lies on the Edwards Plateau, and the remainder lies within the Gulf Coastal Plain. The rocks that crop out in the region are practically all sedimentary and consist chiefly of limestone, shale, clay, sandstone, sand, and gravel. They range in geologic age from Lower Cretaceous to Quaternary. The general geologic structure of the region is comparatively simple. The most prominent features are the regional gulfward dip of the formations at an angle greater than the slope of the land surface, which is a significant factor governing the occurrence of artesian water, and faulting along the Balcones fault zone which controls the occurrence and movement of ground water in the Edwards and associated limestones. Among the most important aquifers are the Edwards limestone of Lower Cretaceous age; the Carrizo sand, sands of the Mount Selman formation, the Oakville sandstone, and the Goliad sand of Tertiary age; and the Lissie formation and sands of the Beaumont clay of Quaternary age. Each of these units has outcrop areas from which the beds dip beneath younger formations to increasingly greater depths. For convenience in summarizing the sources of municipal water supplies, the region has been divided into four areas, as shown on plate 1. In area A, Bandera obtains its water from sands in the Trinity group; Divine in southeastern Medina County obtains water from sands in the Wilcox group or the Carrizo sand; and Boerne in southern Kendall County obtains its supply from Recent alluvium. The remainder of the municipalities in the area obtain water from the Edwards limestone, which has the greatest perennial yield of any aquifer in Texas. In area B, the Carrizo sand is the important aquifer in most of the area, although in the northeastern part several towns that are above the outcrop of the Carrizo sand obtain water from sands in the Wilcox group. In area C, all of the cities and towns use surface water with the exception of Falls City, Gonzales, and Three Rivers. In area D, which is adjacent to the Gulf Coast, the principal sources of ground water are the Catahoula tuff, the Oakville sandstone, sands of the Lagarto clay, the Goliad sand, the Lissie formation, and sands of the Beaumont clay. Most of the public supplies obtained from surface water in Southern Texas are filtered and frequently are given further treatment that alters the chemical character of the water. All except two of the supplies from the Rio Grande are given some chemical treatment and about two-thirds of them are filtered. Of the 182 analyses given in this report, 138 are from we

    Fire can be both an ecosystem stressor (Chapter 2) and a critical ecosystem process, depending on when, where, and under what conditions it occurs on the southern Nevada landscape. Fire can also pose hazards to human life and property, particularly in the wildland/urban interface (WUI). The challenge faced by land managers is to prevent fires from occurring where they are likely to threaten ecosystem integrity or human developments, while allowing fires to occur where they will provide ecosystem benefits. The Southern Nevada Agency Partnership (SNAP) Science and Research Strategy summarizes this desired outcome with Sub-goal 1.1, which is to manage wildland fire to sustain Southern Nevada’s ecosystems (table 1.3; Chapter 1). This chapter provides information that will help land managers develop strategies to achieve this goal. It begins with a background section on fire history, spatial and temporal patterns of fire, and fire effects for the major ecosystem types of southern Nevada, (table 1.1; Chapter 1). Potential fire management actions are then discussed, the overall implications of the information to fire management are summarized, and the major knowledge gaps are described.

    The south-eastern (SEA) margin of Australia has many reported palaeoenvironmental and palaeoclimatic reconstructions from lacustrine environments spanning the Holocene. However, only recently have multi-proxy, high-resolution records with detailed chronologies been reported from this region. In contrast, only one record from the southern margin of Western Australia (SWA) has been published that is of sufficient quality for high-resolution palaeoclimatic interpretation from this region. Historical climate data from SWA and SEA indicate that the precipitation recorded in the two regions is controlled in large part by the Southern Hemisphere Westerly Wind System (WWS) and the associated Indian Ocean Sector - Southern Annular Mode (IOS-SAM). The historical climate of SEA is also significantly affected by the Indian Ocean Dipole (IOD) and to a lesser extent the El Niño Southern Oscillation (ENSO) phenomenon, whereas these two climate drivers have a negligible effect on the climate of SWA. Here we present a comparison of the palaeoclimatic histories of the two regions from the mid-Holocene (7.4 ka to present), and correlate the changes in the climatic histories these with large scale Southern Hemisphere climatic drivers. Both the SEA and SWA regions show a general trend towards aridity which is associated with the southerly migration of the Inter-Tropical Convergence Zone (ITCZ) that progressively displaced the Southern Hemisphere mid-latitude sub-tropical ridge to the south. This in association with a shift to more positive IOS-SAM-like conditions shifted the precipitation-bearing frontal belt to a more mean southerly location resulting in decreased precipitation across southern Australia. The establishment of a significant phase of positive IOD between 5.6 and 4.3 ka uncouples the climate between SWA and SEA. The establishment of modern ENSO and it's co-relationship with the IOD have contributed significantly to the late Holocene history of SEA, whereas SWA only records variation in the IOS-SAM.

    The Southern Ocean is critically important to the oceanic uptake of anthropogenic CO2. Up to half of the excess CO2 currently in the ocean entered through the Southern Ocean. That uptake helps to maintain the global carbon balance and buffers transient climate change from fossil fuel emissions. However, the future evolution of the uptake is uncertain, because our understanding of the dynamics that govern the Southern Ocean CO2 uptake is incomplete. Sparse observations and incomplete model formulations limit our ability to constrain the monthly and annual uptake, interannual variability and long-term trends. Float-based sampling of ocean biogeochemistry provides an opportunity for transforming our understanding of the Southern Ocean CO2 flux. In this work, we review current estimates of the CO2 uptake in the Southern Ocean and projections of its response to climate change. We then show, via an observational system simulation experiment, that float-based sampling provides a significant opportunity for measuring the mean fluxes and monitoring the mean uptake over decadal scales.

    The Southern and Austral Volcanic Zones of the Andes comprise 74 volcanic centres with known post-glacial activity. At least 21 of these have had one or more large explosive eruptions in the late Quaternary, dispersing tephra over vast areas. These tephra layers therefore have great potential as tephrochronological marker horizons in palaeoenvironmental studies in southern Chile and Argentina, a region that is particularly useful to study climate dynamics of the southern hemisphere. However, to date tephrochronology has rarely been fully utilised in this region as a correlation and dating tool. Here we review the existing post-glacial tephrostratigraphic record of the Southern and Austral Volcanic Zones, and compile a database of known occurrences of tephra from these volcanoes in ice and lacustrine, marine, peat, and cave sediment records. We address the inconsistencies in and revisions of the tephrostratigraphies presented in prior literature, and discuss the challenges in correlating tephras and the limitations of the tephrostratigraphic record in this area. This study highlights the many gaps that still exist in our knowledge of the eruptive histories of these volcanoes, but also reveals the largely under-utilised potential of tephra as a correlation tool in this region. This is exemplified by the severe lack of adequate geochemical analysis of tephra layers preserved in many lacustrine and peat sediment sections, which are particularly important tephrostratigraphic records in southern Chile and Argentina due to the paucity of surface preservation.

    We present observations of 82 Local Group dwarf galaxy candidates, of which 62 were chosen visually from ESO-SRC survey plates of the southern sky (32 of which were not previously catalogued) and the rest suggested by various sources in the literature. Two are the Local Group galaxies Antlia and Cetus; nine are more distant galaxies, though still within a few megaparsecs; 45 are background galaxies; seven are planetary (or other emission) nebulae; 15 are reflection or other Galactic nebulae; two are galaxy clusters; one is a Galactic star cluster and one is a misidentified star. We conclude that there is no large population of faint Local Group dwarf galaxies of any familiar type awaiting discovery. We point out the danger of relying on a single type of data to reach conclusions about an object.

    The island of Madagascar occupies a key region in both the assembly and the multi-stage breakup of Gondwanaland, itself part of the super-continent Pangaea. Madagascar consists of an amalgamation of continental material, with the oldest rocks being of Archaean age. Its ancient fabric is characterised by several shear zones, some of them running oblique to the N-S trend, in particular in the south of the island. More recently during the Neogene, moderate volcanism has occurred in the Central and Northern part of the island, and there are indications of uplift throughout Eastern Madagascar over the last 10 Ma. Although Madagascar is now located within the interior of the African plate and far away from major plate boundaries (> 1000 km from the East African rift system and even further from the Central and South-West Indian Ridges), its seismic activity indicates that some deformation is taking place, and present-day kinematic models based on geodetic data and earthquake moment tensors in the global catalogues identify a diffuse N-S-oriented minor boundary separating two microplates, which appears to pass through Madagascar. In spite of the presence of Archaean and Proterozoic rocks continent-wide scale studies indicate a thin lithosphere (<120 km) throughout Madagascar, but are based on sparse data and cannot resolve the difference between eastern and western Madagascar. We are operating a ENE-WSW oriented linear array of 25 broadband stations in southern Madagascar, extending from coast to coast and sampling the sedimentary basins in the west as well as the metamorphic rocks in the East, cutting geological boundaries seen at the surface at high angle. The array crosses the prominent Bongolava-Ranotsara shear zone which is thought to have been formed during Gondwanaland assembly. The array recorded the magnitude 5.3 earthquake of January 25, 2013 which occurred just off its western edge. In addition, in May 2013 we have deployed 25 short period sensors in the eastern part of the study area, where there is some so-far poorly characterised seismicity. We will present preliminary results on the lithospheric crust and mantle structure based on surface wave dispersion and waveform modelling, focussing on the contrast between the metamorphic areas in the east and the presumably stretched regions in the west.

    The work presents the fast and efficient tool for seafloor classification, where scales and shapes of geomorphological forms were taken into account. The precise bathymetry and seafloor texture was developed with multibeam echosounder at six different areas of size up to 10 by 20 km. This areas demonstrate typical geomorphological seafloor features of bottom relief at the southern Baltic Sea coastal waters. The acoustical measurements were accompanied by geological sampling and video inspection. High resolution mosaic maps were obtained as a result of multi-survey measurements with maximal spatial resolution of 0.05m. Such accuracy of the measurements allows to observe small geomorphologic forms as ripplemarks or pebbles. The most investigated polygons have bottom relief of polygenetic origin with relicts of periglacial forms together with contemporary forms of marine origin. In the studied areas different forms of sand accumulation were found, beginning with small ripplemarks ending at big sandy waves. In the seabed erosion zones the bottom surface is rough and varied with clearly formed embankments, abrasive platforms, inselbergs and stony gravely abrasive pavements on the bottom surface. Such geomorphic diversity of the bottom surface has allowed for development of consistent geomorphological classification system based mainly on spectral properties of seafloor roughness. Each analysed area was divided into squares (200 by 200 m) with an overlap between adjacent subareas of 75% a square size. Next, subdivided areas were spectrally transformed using a two dimensional fast Fourier transform (2D FFT). The spectral parameters as maximal value of spectral density function, spectral exponent and strength, spectral moments, mean frequency, spectral width and skewness for each characteristic type of bottom surface were determined relaying on the calculated 2D spectra. Moreover, other features characterised the corrugated surface as fractal dimension, radius of autocorrelation, elevation slope, statistical and wavelet transformation parameters were estimated. The set of parameters was the input to the Principal Component Analysis and next to the unsupervised neural network algorithm which produced maps containing morphologically classified seabed areas. The obtained results revealed that acoustical technique provides very useful capabilities for the seafloor characterisation.

  5. Large Craters in Callisto's Southern Hemisphere

    NASA Technical Reports Server (NTRS)

    1997-01-01

    NASA's Galileo spacecraft provides a new view of this heavily cratered region in the southern hemisphere of the icy Jovian satellite Callisto. The region was not observed by NASA's Voyager spacecraft. Craters ranging in diameter from the 1.85 kilometer (1.13 mile) limit of resolution up to more than 70 kilometers (43 miles) can be observed in this image. Although all craters are generally round in outline, details in their structures vary with both size and relative age. Bright spots in the center of smaller craters (up to approximately 20 kilometers (12 miles)) are central peaks. Larger craters (up to the 51 kilometer (31 mile) wide crater in the east central part of the image) exhibit central pits or depressions. The largest crater, called Thrainn, has a diameter of 74 kilometers (45 miles) and is located in the southernmost corner of the image. This crater contains a broad central uplift, or dome, and has a highly eroded rim. In contrast, the 70 kilometer (43 mile) crater Audr, located along the northern margin of the image, is flat-bottomed, and has a less degraded and generally rounder rim. If erosional or degradational forces have been roughly constant with time on Callisto, scientists viewing this image can assume that Audr is relatively younger than Thrainn by noting the less degraded or fresher appearance of its rim. The differences in crater floor features between these two similarly sized craters could have been produced by differences in the impacting bodies that produced them, differences in the crustal materials in which the craters formed, or simply by a gradual evolution of crater floor shape with time.

    North is to the top of the image which was taken by the Galileo spacecraft's solid state imaging (CCD) system during its eighth orbit around Jupiter on May 6th, 1997. The center of the image is located at 34 degrees south latitude, 84 degrees west longitude, and was taken when the spacecraft was approximately 48,430 kilometers (29,542 miles) from Callisto.

  6. Measurement of Wetland Evapotranspiration in Southern Florida

    NASA Astrophysics Data System (ADS)

    Bernier, T.; Lopez, C.; Shoemaker, W. B.

    2009-12-01

    Evapotranspiration (ET) is defined as a composite flux of surface water directly evaporated by solar energy, and ground water transpired by plants. Factors limiting ET include the available energy, available water, and the vapor transport resistance offered by the atmosphere and vegetation. ET is surprisingly understudied considering its dominance in the hydrologic cycle transporting as much as 80% to over 100% of rainfall back into the atmosphere as water vapor. Uncertainties in spatial and temporal ET estimates limit the reliability of hydrologic water budgets and therefore can complicate development of sustainable water-use strategies and resolution of conflicts over water. In response to ET uncertainties, a monitoring station was constructed over a wet-prairie wetland in Big Cypress National Preserve in southern Florida to measure latent heat flux (the energy equivalent of ET), rainfall, air and water temperature, wind speed and direction, wind gusts, solar radiation, net radiation, soil-heat flux, relative humidity, and depth-of-water above or below land surface. The monitoring station was located on a 12' tower for atmospheric sampling at distances roughly 6' to 8' above the wet prairie canopy. Data are presented for a full year; specifically, June 16th, 2007 to June 16th, 2008. The eddy covariance method was applied to measure ET. The mean daily ET total was about 2.8 millimeters per day. Maximum values of about 3.5 to 5 millimeters per day were measured during the summer months (April to September) when solar radiation was greatest. Minimum values of 0 to about 2.5 millimeters per day were measured during the winter months (October to March) when solar radiation was relatively small. Sub-daily ET variations were explained mostly by available energy; formulated as the difference between net radiation, the soil-heat flux, and changes in heat-energy stored in the soil and surface-water. The annual ET total was about 1050 millimeters per year (41 inches per year). This compared to a rainfall total of about 955 millimeters per year (38 inches per year). Thus, the net atmospheric input (Rainfall - ET) was about -100 mm per year (-3 inches per year) at the wet prairie site for the year.

  7. Southern Florida, Shaded Relief and Colored Height

    NASA Technical Reports Server (NTRS)

    2004-01-01

    The very low topography of southern Florida is evident in this color-coded shaded relief map generated with data from the Shuttle Radar Topography Mission. The image on the left is a standard view, with the green colors indicating low elevations, rising through yellow and tan, to white at the highest elevations. In this exaggerated view even those highest elevations are only about 60 meters (197 feet) above sea level.

    For the view on the right, elevations below 5 meters (16 feet) above sea level have been colored dark blue, and lighter blue indicates elevations below 10 meters (33 feet). This is a dramatic demonstration of how Florida's low topography, especially along the coastline, make it especially vulnerable to flooding associated with storm surges. Planners can use data like these to predict which areas are in the most danger and help develop mitigation plans in the event of particular flood events.

    Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Geospatial-Intelligence Agency (NGA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Science Mission Directorate, Washington, D.C.

  10. Did the Taconic Appalachians continue into southern South America?

    NASA Astrophysics Data System (ADS)

    Dalla Salda, Luis H.; Dalziel, Ian W. D.; Cingolani, Carlos A.; Varela, Ricardo

    1992-12-01

    The Appalachian Mountains, now terminating abruptly at the Gulf of Mexico coastal plain, may have formerly continued into southern South America. Rocks forming the basement of the Argentine Andes can be interpreted as remnants of an early Paleozoic orogen, the Famatinian belt, not unlike the Taconic Appalachians. Both orogens are bordered to the west (present coordinates) by lower Paleozoic carbonate platforms bearing the Olenellid trilobite fauna that is characteristic of Laurentia. Paleomagnetic and geologic data indicate that they could have formed as one continuous mountain chain, possibly extending into Antarctica, during Ordovician closure of an ocean basin ("southern" Iapetus) between Laurentia and Gondwana. The Taconic and Famatinian segments of the chain may have been truncated during Late Ordovician separation of Laurentia and Gondwana along the preexisting (late Neoproterozoic to Cambrian) rift system that initiated formation of the Ouachita embayment and the southern margin of North America.

  11. Southern Ocean exports carbon less efficiently than previously thought

    NASA Astrophysics Data System (ADS)

    Balcerak, Ernie

    2013-07-01

    The Southern Ocean is a major source of gas exchange between the atmosphere and the ocean, accounting for almost 20% of global ocean carbon dioxide (CO2) uptake. Phytoplankton fix CO2, converting it to other carbon compounds, and some of this biogenic carbon sinks to the deeper ocean, where it is effectively removed from the atmosphere. Better understanding of the rate of export of carbon particulate matter from the upper ocean is key to improving uncertainties in models that include the Southern Ocean's role in the carbon cycle.

    An oblique view of the southern part of the Sea of Okhotsk, north of Japan, (45.0N,144.0E) as photographed from the Skylab space station in Earth orbit by one of the Skylab 4 crewmen. Most of the land area is Hokkaido Island, Japan. The southern tip of Sakhalin Island (Soviet Union) is in the northwest corner. This photograph was taken to aid in the study of the formation of sea ice. Observations in the Sea of Okhotsk are of interest because the ice has a morphology similar to that of the Bering Sea.

    1999-03-01

    Aircraft laser-altimeter surveys over southern Greenland in 1993 and 1998 show three areas of thickening by more than 10 centimeters per year in the southern part of the region and large areas of thinning, particularly in the east. Above 2000 meters elevation the ice sheet is in balance but thinning predominates at lower elevations, with rates exceeding 1 meter per year on east coast outlet glaciers. These high thinning rates occur at different latitudes and at elevations up to 1500 meters, which suggests that they are caused by increased rates of creep thinning rather than by excessive melting. Taken as a whole, the surveyed region is in negative balance. PMID:10066172

  15. [Traditional diet in Southern Italy, between myth and reality].

    2013-01-01

    "Mediterranean diet" is commonly defined as a type of diet based on traditional foods of the Southern Italian regions, assuming that in the past the southern populations enjoyed a balanced and healthy diet. In fact, up to the middle of the twentieth century, widespread poverty in large parts of the population led to malnutrition due to lack of calories and essential nutrients. Only among the upper classes consumption of food was reasonable and respectful of the recommendations of the "Mediterranean diet pyramid". The fact remains that many traditional dishes can be recommended because they are well balanced on nutrients, tasty and appetizing. PMID:23598809

    Singular spectrum analysis (SSA), a variant of principal component analysis, is applied to a time series of the Southern Oscillation index (SOI). The analysis filters out variability unrelated to the Southern Oscillation and separates the high-frequency, 2- to 3-year variability, including the quasi-biennial oscillation, from the lower-frequency 4- to 6-year El Nino cycle. The maximum entropy method (MEM) is applied to forecasting the prefiltered SOI. Prediction based on MEM-associated autoregressive models has useful skill for 30-36 months. A 1993-1994 La Nina event is predicted based on data through February 1992. 52 refs., 4 figs.

    Anopheles stephensi mysorensis is an important malaria vector in southern Iran. It is known to be the vector of malaria in Abadan, Bandar Abbas, Kazeroun and Dezful. It readily attacks man. Precipitan tests on specimens from different parts of southern Iran showed that 15.7% were positive for human blood. This species usually rests indoors, but a small proportion of its population has been caught outdoors. Larval habitats vary. This species is resistant to DDT and Dieldrin in most of the areas of the Persian Gulf and Oman sea. PMID:1006792

    The rate of slow deformation processes along faults activated during the Landers 1992 earthquake was investigated. The analysis was performed by combining pairs of ERS-1/2 synthetic aperture radar (SAR) of Southern California (U.S.). The interferograms revealed several centimeters of post-seismic rebound in step-overs of the 1992 break. The southern branches of the 1992 break experienced surface creep, producing sharp phase cuts in the interferometric maps. The same approach was used in the Los Angeles (CA) basin. The tectonic signal in the interferograms of the Los Angeles basin was intermingled with signals due to ground subsidence caused by oil and water withdrawal.

    1983-01-01

    The effect of strong amplitude and high frequency oscillations of divergent circulations in the Southern Hemisphere on estimates of tropical geopotential during the summer is quantified. FGGE data are analyzed in order to determine the mass-flow balance in the upper troposphere, and outgoing longwave radiation averaged over two periods, January and February 1979, is given. It is found that the divergence terms for balance equations may represent geopotential perturbations on the order of 20 to 30 m, and that the influence of strong latent heat releases and divergent circulations in the Southern Hemisphere can invalidate analysis schemes based on quasi-nondivergent solutions.

  3. Maintaining and restoring sustainable ecosystems in southern Nevada: Chapter 7 in The Southern Nevada Agency Partnership science and research synthesis: science to support land management in southern Nevada

    Managers in southern Nevada are challenge with determining appropriate goals and objectives and developing viable approaches for maintaining and restoring sustainable ecosystems in a time of rapid socio-ecological and environmental change. Sustainable or "healthy" ecosystems supply clean air, water and habitat for a diverse array of plants and animals. As described in Chapter 1, sustainable ecosystems retain characteristic processes like hydrological flux and storage, geomorphic processes, biogeochemical cycling and storage, biological activity and productivity, and population regeneration and reproduction over the normal cycle of disturbance events (modified from Chapin and others 1996 and Christensen and others 1996). Ecological restoration of stressed or disturbed ecosystems in an integral part of managing for sustainable ecosystems. The Society of Ecological Restoration International (SERI) defines ecological restoration as the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed (SERI 2004). Many of the southern Nevada's ecosystems are being subjected to anthropogenic stressors that span global, regional, and local scales (Chapter 2)., and are crossing ecological thresholds to new alternative states (Chapter 4 and Chapter 5). These alternative states often represent novel communities with disturbance regimes that differ significantly from historic conditions. Past management and restoration goals often focused on returning ecosystems to pre-disturbance conditions (Harris and others 2006). This approach assumes stable or equilibrium conditions and ignores changes in ecosystems processes due to land uses, increases in CO2 concentrations, and climate change. A more realistic approach is to base management and restoration goals on the current potential of an ecosystem to support a given set of ecological conditions, and on the likelihood of future change due to warming climate (Harris and others 2006). This approach requires understanding ecosystem resilience to anthropogenic disturbance and climate change, the alternative states that exist for ecosystems, and the factors that result in threshold crossing (Bestelmeyer and others 2009; Hobbs and Harris 2001; Stingham and others 2003; Whisemnant 1999). It also requires the ability to predict how climate is likely to influence ecosystems in the future (Harris and others 2006). This chapter addresses the restoration aspects of Sub-goal 1.3 in the SNAP Science Research Strategy which is to restore and sustain proper function of southern Nevada's watersheds and landscapes (able 1.3; Turner and others 2009). The effects of global, regional and local stresses on southern Nevada ecosystems are presented in Chapter 2. Here, we discuss appropriate objectives and develop guidelines for maintaining and restoring southern Nevada ecosystems. We then discuss the differences in ecological resilience to stress and disturbance and resistance to invasive species in southern Nevada ecosystems and describe restoration and management approaches for the different ecosystem types. We conclude with knowledge gaps and management implications.

  4. Invasive species in southern Nevada: Chapter 4 in The Southern Nevada Agency Partnership science and research synthesis: science to support land management in southern Nevada

    Southern Nevada contains a wide range of topographies, elevations, and climactic zones emblematic of its position at the ecotone between the Mojave Desert, Great Basin, and Colorado Plateau ecoregions. These varied environmental conditions support a high degree of biological diversity (Chapter 1), but they also provide opportunities for a wide range of invasive species. In addition, the population center of the Las Vegas valley, and the agricultural area scattered throughout Clark, Lincoln, and Nye counties, all connected by a network of roads and highways, plus ephemeral and perennial watercourses, provide abundant opportunities for new invaders to be transported into and within southern Nevada (Brooks 2009; Brookes and Lair 2009). Invasive species are a concern for land managers because they can compete directly with native species (Brooks 2000; Chambers and others 2007; DeFlaco and others 2003, 2007; Mazzola and others 2010), change habitat conditions (Brooks and Esque 2002; Esque and others 2010; Miller and others 2011), and alter ecosystems properties (Brooks and Matchett 2006; Brooks and Pyke 2001; Evans and others 2001). Many invasive species have already established and spread to the point that they are now considered to pose significant problems in southern Nevada. However, there are likely many more than have wither not been transported to or colonized the region, or have established by for various reasons not spread or increased in abundance to the point where they have a significant impact. Land managers must understand both current and potential future problems posed by invasive species to appropriately prioritize management actions. This chapter addressed Sub-goal 1.2 in the SNAP Science Research Strategy (table 1.3; Turner and others 2009), which is to protect southern Nevada's ecosystems from the adverse impacts of invasive species. It provides a brief overview of the key concepts associated with the ecology and management of invasive species, and includes information relevant to all five strategic goals identified by the National Invasive Species Council: prevention, early detection and rapid response, control and management, restoration, and organization collaboration (National Invasive Species Council 2001, 2008). Restoration also is discussed in a broader context in Chapter 5 and 7. This chapter does not present a comprehensive review of all invasive species associated land management issues in southern Nevada, but rather uses key species of concern to illustrate invasion ecology concepts and management strategies. It is focused on terrestrial and aquatic plants and animals, and does not address potential invasive taxa from the other Kingdoms. The information presented herein is intended to provide a foundation upon which land management plans can be developed and project-level decisions can be made relative to the management of invasive species in southern Nevada.
