Many innovations were displayed under the category, ``thermal treatment of air pollutants.`` New technologies include the following: regenerative thermal oxidizers; wet systems for removing pollutants; biological scrubbers;electrostatic precipitators; selective adsorption systems; activated-coke adsorbers; optimization of scrubber systems; and air pollution monitors.

  3. Oahu, Hawaii

    NASA Technical Reports Server (NTRS)

    2000-01-01

    This 60 by 55 km ASTER scene shows almost the entire island of Oahu, Hawaii on June 3, 2000. The data were processed to produce a simulated natural color presentation. Oahu is the commercial center of Hawaii and is important to United States defense in the Pacific. Pearl Harbor naval base is situated here. The chief agricultural industries are the growing and processing of pineapples and sugarcane. Tourism also is important to the economy. Among the many popular beaches is the renowned Waikiki Beach, backed by the famous Diamond Head, an extinct volcano. The largest community, Honolulu, is the state capital.

    The image is located at 21.5 degrees north latitude and 158 degrees west longitude.

    Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface.

    The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats, monitoring potentially active volcanoes, identifying crop stress, determining cloud morphology and physical properties

  15. AirShow 1.0 CFD Software Users' Guide

    NASA Technical Reports Server (NTRS)

    Mohler, Stanley R., Jr.

    2005-01-01

    AirShow is visualization post-processing software for Computational Fluid Dynamics (CFD). Upon reading binary PLOT3D grid and solution files into AirShow, the engineer can quickly see how hundreds of complex 3-D structured blocks are arranged and numbered. Additionally, chosen grid planes can be displayed and colored according to various aerodynamic flow quantities such as Mach number and pressure. The user may interactively rotate and translate the graphical objects using the mouse. The software source code was written in cross-platform Java, C++, and OpenGL, and runs on Unix, Linux, and Windows. The graphical user interface (GUI) was written using Java Swing. Java also provides multiple synchronized threads. The Java Native Interface (JNI) provides a bridge between the Java code and the C++ code where the PLOT3D files are read, the OpenGL graphics are rendered, and numerical calculations are performed. AirShow is easy to learn and simple to use. The source code is available for free from the NASA Technology Transfer and Partnership Office.

  16. X-31 Unloading Returning from Paris Air Show

    NASA Technical Reports Server (NTRS)

    1995-01-01

    After being flown in the Paris Air Show in June 1995, the X-31 Enhanced Fighter Maneuverability Technology Demonstrator Aircraft, based at the NASA Dryden Flight Research Center, Edwards Air Force Base, California, is off-loaded from an Air Force Reserve C-5 transport after the ferry flight back to Edwards. At the air show, the X-31 demonstrated the value of using thrust vectoring (directing engine exhaust flow) coupled with advanced flight control systems to provide controlled flight at very high angles of attack. The X-31 Enhanced Fighter Maneuverability (EFM) demonstrator flew at the Ames- Dryden Flight Research Facility, Edwards, California (redesignated the Dryden Flight Research Center in 1994) from February 1992 until 1995 and before that at the Air Force's Plant 42 in Palmdale, California. The goal of the project was to provide design information for the next generation of highly maneuverable fighter aircraft. This program demonstrated the value of using thrust vectoring (directing engine exhaust flow) coupled with an advanced flight control system to provide controlled flight to very high angles of attack. The result was a significant advantage over most conventional fighters in close-in combat situations. The X-31 flight program focused on agile flight within the post-stall regime, producing technical data to give aircraft designers a better understanding of aerodynamics, effectiveness of flight controls and thrust vectoring, and airflow phenomena at high angles of attack. Stall is a condition of an airplane or an airfoil in which lift decreases and drag increases due to the separation of airflow. Thrust vectoring compensates for the loss of control through normal aerodynamic surfaces that occurs during a stall. Post-stall refers to flying beyond the normal stall angle of attack, which in the X-31 was at a 30-degree angle of attack. During Dryden flight testing, the X-31 aircraft established several milestones. On November 6, 1992, the X-31 achieved

  17. Stereo Pair, Honolulu, Oahu

    NASA Technical Reports Server (NTRS)

    2000-01-01

    Honolulu, on the island of Oahu, is a large and growing urban area. This stereoscopic image pair, combining a Landsat image with topography measured by the Shuttle Radar Topography Mission (SRTM), shows how topography controls the urban pattern. This color image can be viewed in 3-D by viewing the left image with the right eye and the right image with the left eye (cross-eyed viewing), or by downloading and printing the image pair, and viewing them with a stereoscope.

    Features of interest in this scene include Diamond Head (an extinct volcano near the bottom of the image), Waikiki Beach (just above Diamond Head), the Punchbowl National Cemetary (another extinct volcano, near the image center), downtown Honolulu and Honolulu harbor (image left-center), and offshore reef patterns. The slopes of the Koolau mountain range are seen in the right half of the image. Clouds commonly hang above ridges and peaks of the Hawaiian Islands, but in this synthesized stereo rendition appear draped directly on the mountains. The clouds are actually about 1000 meters (3300 feet) above sea level.

    This stereoscopic image pair was generated using topographic data from the Shuttle Radar Topography Mission, combined with a Landsat 7 Thematic Mapper image collected at the same time as the SRTM flight. The topography data were used to create two differing perspectives, one for each eye. When stereoscopically merged, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions. The United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota, provided the Landsat data.

    The Shuttle Radar Topography Mission (SRTM), launched on February 11, 2000, 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. The mission was designed to collect three-dimensional measurements of the

  5. STS-65 Earth observation of island wake at Oahu, Hawaii, taken from OV-102

    NASA Technical Reports Server (NTRS)

    1994-01-01

    STS-65 Earth observation taken aboard Columbia, Orbiter Vehicle (OV) 102, shows Oahu, Hawaii. The island wake emerging to the lower left side of Oahu is caused by wind currents blowing from the northeast being obstructed by the northwest-southeast trending, cloud covered, Koolau mountain range. The lighter colored water indicates a more smooth surface with a slower water current that the darker, rougher, faster moving water current. Pearl Harbor is visible to the south of the Koolau Range. To the right, or east, of Pearl Harbor is the city of Honolulu. The circular, brown feature to the east of Honolulu is the dormant volcano Diamond Head.

  6. F-18 SRA closeup of nose cap showing new flush air data system sensor holes

    1997-01-01

    The small numbers on the nose of this F-18 aircraft at NASA's Dryden Flight Research Center, Edwards, California, show the locations of 11 tiny holes which are an integral part of a new air data system installed on the aircraft. The Real-Time Flush Air Data Sensing system measures the speed and direction of the airflow past the aircraft and its altitude, similar to standard air data systems. It incorporates flush-mounted pressure taps, miniature transducers and an advanced research computer to give pilots more accurate information than standard systems employing external probes can provide. Developed by Dryden researchers in cooperation with Honeywell's Research and Technology Center, Minneapolis, Minnesota, the system was flight tested on Dryden's Systems Research Aircraft (SRA) last year, and is now being used as a precise reference for other air data systems currently being evaluated on the modified F-18.

    1997-01-01

    Small numbers on the nose cap of this F-18 Systems Research Aircraft at NASA's Dryden Flight Research Center, Edwards, California, show the locations of 11 tiny holes, which are an integral part of a new air data system installed on the aircraft. The Real-Time Flush Air Data Sensing system measures the speed and direction of the airflow past the aircraft and its altitude, similar to standard air data systems. It differs from those systems by incorporating flush-mounted pressure taps, miniature transducers and an advanced research computer to give the pilot more accurate information than systems employing external probes provide. Stephen A. Whitmore of Dryden's Aerodynamics Branch won NASA's Space Act Award for his development of the Real-Time Flush Air Data Sensing system. The award honors projects which are scientifically or technologically significant to the aeronautics and space community. The system was flight tested on the modified F-18 last year, and is now being used as a precise reference system for other air data systems currently being evaluated on the aircraft.

  2. In vivo microvascular mosaics show air embolism reduction after perfluorocarbon emulsion treatment.

    PubMed

    2012-11-01

    Massive arteriolar gas embolism (AGE) has never been evaluated in vivo using intravital microscopy and previous perfluorocarbon (PFC) emulsions were only effective in AGE when administered before AGE. We implemented a new system for quantitative studies of massive AGE using brightfield microscopy and tested a treatment with a third-generation PFC emulsion after massive AGE. We studied bubble dynamics in cremaster muscles from anesthetized rats after AGE was induced by direct air injection into the femoral artery ipsilateral to the studied muscle. Using a motorized microscope stage and a color camera, in vivo microvascular mosaics were produced on-line from over 2000 digital images to evaluate multiple networks in order to investigate the distribution, lodging, breaking, reduction and moving of 105 air bubbles in microvessels. Thirty minutes after PFC treatment, there was a reduction of 80% in bubble volume while untreated and saline-treated rats showed significantly smaller decreases of 33% and 40%, respectively (p<0.05). Air bubbles also dissolved into a larger number of smaller bubbles after PFC treatment. The proposed methodology may prove useful for rapid in vivo data acquisition from large networks. Since large air bubbles broke-up, decreased in length and volume, and moved toward smaller microvessels, the study provides quantitative data to support a mechanism by which PFC may improve tissue blood flow following massive AGE. The findings suggest that this new generation of PFC emulsions administered after severe AGE may reach compromised microvascular networks and provide help to alleviate microvascular obstruction by increasing air bubble reabsorption.

  3. Space Radar Image of Honolulu, Oahu, Hawaii

    NASA Technical Reports Server (NTRS)

    1994-01-01

    This spaceborne radar image shows the city of Honolulu, Hawaii and adjacent areas on the island of Oahu. Honolulu lies on the south shore of the island, along the bottom of this image. Diamond Head, an extinct volcanic crater, is seen in the lower right. The bright white strip left of Diamond Head is the Waikiki Beach area. Further west are the downtown area and harbor. Runways of the airport can be seen in the lower left. The Koolau mountain range runs through the center of the image. The steep cliffs on the north side of the range are thought to be remnants of massive landslides that ripped apart the volcanic mountains that built the island thousands of years ago. On the north shore of the island are the Mokapu peninsula and Kaneohe Bay. Densely vegetated areas appear green in this radar image, while urban areas generally appear orange, red or white. Images such as this can be used by land use planners to monitor urban development and its effect on the tropical environment. The image was acquired by the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) onboard the space shuttleEndeavour on October 6, 1994.The image is 20.6 kilometers by 31.0kilometers (12.8 miles by 19.2 miles) and is centered at 21.4degrees North latitude, 157.8 degrees West longitude. North is toward the upper left. The colors are assigned to different radarfrequencies and polarizations of the radar as follows: red is L-band, horizontally transmitted and received; green is L-band, horizontally transmitted, vertically received; and blue is C-band, horizontally transmitted, vertically received. SIR-C/X-SAR,a joint mission of the German, Italian, and United States space agencies, is part of NASA's Mission to Planet Earth.

  4. Carbonate sediment deposits on the reef front around Oahu, Hawaii

    2004-01-01

    Large sediment deposits on the reff front around Oahu are a possible resource for replenishing eroded beaches. High-resolution subbottom profiles clearly depict the deposits in three study areas: Kailua Bay off the windward coast, Makua to Kahe Point off the leeward coast, and Camp Erdman to Waimea off the north coast. Most of the sediment is in water depths between 20 and 100 m, resting on submerged shelves created during lowstands of sea level. The mapped deposits have a volume of about 4 ?? 108 m3 in water depths less than 100 m, being thickest off the mouth of channels carved into the modern insular shelf, from which most of the sediment issues. Vibracore samples contain various amounts of sediment of similar size to the sand on Oahu beaches, with the most compatible prospects located off Makaha, Haleiwa, and Camp Erdman, and the least compatible ones located in Kailua Bay. Laboratory tests show a positive correlation of abrasion with Halimeda content: samples from Kailua Bay suffered high amounts of attrition, but others were comparable to tested beach samples. The common gray color of the offshore sediment, aesthetically undesirable for sand on popular tourist beaches, was diminished in the laboratory by soaking in heated hydrogen peroxide. ??

  16. Perspective view, Landsat overlay Oahu, Hawaii

    NASA Technical Reports Server (NTRS)

    2000-01-01

    Honolulu, on the island of Oahu, is a large and growing urban area with limited space and water resources. This perspective view, combining a Landsat image with SRTM topography, shows how the topography controls the urban growth pattern, causes cloud formation, and directs the rainfall runoff pattern. Features of interest in this scene include downtown Honolulu (right), Honolulu Harbor (right), Pearl Harbor (center), and offshore reef patterns (foreground). The Koolau mountain range runs through the center of the image. On the north shore of the island are the Mokapu Peninsula and Kaneohe Bay (upper right). Clouds commonly hang above ridges and peaks of the Hawaiian Islands, and in this rendition appear draped directly on the mountains. The clouds are actually about 1000 meters (3300 feet) above sea level. High resolution topographic and image data allow ecologists and planners to assess the effects of urban development on the sensitive ecosystems in tropical regions.

    This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat 7 satellite image over an SRTM elevation model. Topography is exaggerated about six times vertically. The Landsat 7 image was acquired on February 12, 2000, and was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS)Data Center, Sioux Falls, South Dakota.

    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

  17. A submarine perspective of the Honolulu Volcanics, Oahu

    Clague, David A.; Paduan, Jennifer B.; McIntosh, William C.; Cousens, Brian L.; Davis, Alicé S.; Reynolds, Jennifer R.

    2006-03-01

    Lavas and volcaniclastic deposits were observed and collected from 4 submarine cones that are part of the Honolulu Volcanics on Oahu, Hawaii. The locations of these and a few additional, but unsampled, vents demonstrate that nearly all the vents are located on or very close to the shoreline of Oahu, with the most distal vent just 12 km offshore. The clastic samples and outcrops range from coarse breccias to cross-bedded ash deposits and show that explosive volcanism at depths between about 350 and 590 m depth played a part in forming these volcanic cones. The eruptive styles appear to be dominantly effusive to strombolian at greater depths, but apparently include violent phreatomagmatic explosive activity at the shallower sites along the submarine southwest extension of the Koko Rift. The compositions of the recovered samples are broadly similar to the strongly alkalic subaerial Honolulu Volcanics lavas, but the submarine lavas, erupted further from the Koolau caldera, have slightly more radiogenic Sr isotopic ratios, and trace element patterns that are distinct from either the subaerial Honolulu Volcanics or the submarine North Arch lavas. These patterns are characterized by moderate to strong positive Sr and P anomalies, and moderate to strong negative Cs, Rb, U, Th, Zr, and Hf anomalies. Most samples have strong negative K and moderate negative Ti anomalies, as do all subaerial Honolulu Volcanics and North Arch samples, but one group of samples from the Koko Rift lack this chemical signature. The data are consistent with more garnet in the source region for the off-shore samples than for either the on-shore Honolulu Volcanics lavas. New Ar-Ar ages show that eruptions at the submarine vents and Diamond Head occurred between about 0.5 Ma and 0.1 Ma, with the youngest ages from the Koko Rift. These ages are in general agreement with most published ages for the formation and suggest that some much younger ages reported previously from the Koko Rift are probably

  18. Shelf stratigraphy and the influence of antecedent substrate on Holocene reef development, south Oahu, Hawaii

    USGS Publications Warehouse

    Grossman, E.E.; Barnhardt, W.A.; Hart, P.; Richmond, B.M.; Field, M.E.

    2006-01-01

    Paired analyses of drill cores and high-resolution seismic reflection data show that development of Holocene framework reefs on the Oahu (Hawaii) shelf is limited to settings of low wave energy and to the period 8000 to 3000 yr BP. A prominent bounding surface that is mapped across much of the Oahu shelf is an erosion surface cut into Marine Isotope Stages 5 and 7 limestones that show extensive loss of primary porosity, aragonite, and MgCO3 owing to meteoric and vadose-zone diagenesis. This acoustic reflector is found exposed at the surface where wave energy is high or in the shallow subsurface below Holocene reef and sand sheet deposits where energy is low. Ship-towed video along 30 km of the shelf reveals a steady decrease in limestone accumulation from offshore of Honolulu southeast to Koko Head where the seafloor is characterized by volcanic pavement and/or thin sand deposits. This may reflect the build-up of late Pleistocene volcanics associated with the Hanauma Bay eruption (30,000-7000 yr BP) that now comprise the substrate in depths shallow enough to limit reef accretion. The absence of significant Holocene reef build-up on the south Oahu shelf is consistent with observations from north-facing coasts that lack Holocene reefs, indicating that Holocene reef formation in Hawaii is complex and patchy. ?? 2005 Elsevier B.V.

    Methanosarcina acetivorans, considered a strict anaerobic archaeon, was cultured in the presence of 0.4–1% O2 (atmospheric) for at least 6 months to generate air-adapted cells; further, the biochemical mechanisms developed to deal with O2 were characterized. Methane production and protein content, as indicators of cell growth, did not change in air-adapted cells respect to cells cultured under anoxia (control cells). In contrast, growth and methane production significantly decreased in control cells exposed for the first time to O2. Production of reactive oxygen species was 50 times lower in air-adapted cells versus control cells, suggesting enhanced anti-oxidant mechanisms that attenuated the O2 toxicity. In this regard, (i) the transcripts and activities of superoxide dismutase, catalase and peroxidase significantly increased; and (ii) the thiol-molecules (cysteine + coenzyme M-SH + sulfide) and polyphosphate contents were respectively 2 and 5 times higher in air-adapted cells versus anaerobic-control cells. Long-term cultures (18 days) of air-adapted cells exposed to 2% O2 exhibited the ability to form biofilms. These data indicate that M. acetivorans develops multiple mechanisms to contend with O2 and the associated oxidative stress, as also suggested by genome analyses for some methanogens. PMID:25706146

    This L-shaped probe mounted on the forward fuselage of a modified F-18 Systems Research Aircraft was the focus of an air data collection experiment flown at NASA's Dryden Flight Research Center, Edwards, California. The Advanced L-Probe Air Data Integration (ALADIN) experiment focused on providing pilots with angle-of-attack and angle-of-sideslip information as well as traditional airspeed and altitude data from a single system. For the experiment, the probes--one mounted on either side of the F-18's forward fuselage--were hooked to a series of four transducers, which relayed pressure measurements to an on-board research computer.

    This under-the-nose view of a modified F-18 Systems Research Aircraft at NASA's Dryden Flight Research Center, Edwards, California, shows three critical components of the aircraft's air data systems which are mounted on both sides of the forward fuselage. Furthest forward are two L-probes that were the focus of the recent Advanced L-probe Air Data Integration (ALADIN) experiment. Behind the L-probes are angle-of-attack vanes, while below them are the aircraft's standard pitot-static air data probes. The ALADIN experiment focused on providing pilots with angle-of-attack and angle-of-sideslip air data as well as traditional airspeed and altitude information, all from a single system. Once fully developed, the new L-probes have the potential to give pilots more accurate air data information with less hardware.

  2. Observations of the trade wind wakes of Kauai and Oahu

    2008-02-01

    The Hawaiian islands of Kauai and Oahu stand in the path of the east-northeasterly trade winds, creating wakes in the lee. For the first time, the structure of the wakes and their diurnal cycle were observed on a cruise during 18-20 December 2006. The dynamic wakes, characterized by reduced trades, extend about 1 km in height with strong wind shear at the top. Thermal forcing of these small islands also affects the wake circulations. Sea breezes develop in the afternoon turning the winds into westerly near the shore in the wakes. At night, land breezes advect cool air from the islands, creating a shallow cool layer between the sea surface and a capping inversion. The warming in the wake in the afternoon extends much deeper (1.4 km) than the cool layer (0.5 km) at night. The effect of diurnal changes on cloud formation in the wakes is discussed, and the sharp variations in wind velocity lee of the islands may affect ocean currents, waves and mixing.

  3. Environmental Setting and the Effects of Natural and Human-Related Factors on Water Quality and Aquatic Biota, Oahu, Hawaii

    Oki, Delwyn S.; Brasher, Anne M.D.

    2003-01-01

    -use patterns on Oahu reflected increases in population and decreases in large-scale agricultural operations over time. The last two remaining sugarcane plantations on Oahu closed in the mid-1990's, and much of the land that once was used for sugarcane now is urbanized or used for diversified agriculture. Although two large pineapple plantations continue to operate in central Oahu, some of the land previously used for pineapple cultivation has been urbanized. Natural and human-related factors control surface- and ground-water quality and the distribution and abundance of aquatic biota on Oahu. Natural factors that may affect water quality include geology, soils, vegetation, rainfall, ocean-water quality, and air quality. Human-related factors associated with urban and agricultural land uses also may affect water quality. Ground-water withdrawals may cause saltwater intrusion. Pesticides and fertilizers that were used in agricultural or urban areas have been detected in surface and ground water on Oahu. In addition, other organic compounds associated with urban uses of chemicals have been detected in surface and ground water on Oahu. The effects of urbanization and agricultural practices on instream and riparian areas in conjunction with a proliferation of nonnative fish and crustaceans have resulted in a paucity of native freshwater macrofauna on Oahu. A variety of pesticides, nutrients, and metals are associated with urban and agricultural land uses, and these constituents can affect the fish and invertebrates that live in the streams.

    2010-03-16

    Seventeen measurement stations in the south western region of the island of Oahu collected data at 1-second intervals over the course of a year. The sensors are located in a 1-kilometer grid and the information then can be used to predict what PV outputs might be at 1-second intervals for medium-sized and large PV systems. This DOE-funded study by NREL supports the Hawaii Clean Energy Initiative (HCEI), a multifaceted program to substantially increase the use of renewable energy in Hawaii.

  9. Environmental features and macrofauna of Kahana Estuary, Oahu, Hawaii

    1981-01-01

    Lack of ecological information on Hawaiian estuaries prompted an intensive 2-year study of a small (5.7 ha) stream-mouth estuary on windward Oahu. Water quality and macrofauna were sampled weekly at seven stations. The water mass was strongly stratified vertically except during freshets. Average values for water column temperature and bottom salinity were 23.2°C and 12‰ at the head to 28.3°C and 28‰ at the mouth. Dissolved oxygen saturation in the water column varied from about 50% at night to 140% in the afternoon. Usually, bottom waters were 3–6°C warmer than surface waters and sometimes showed severe oxygen depletion.Macrofauna, collected primarily by seining, consisted mainly of decapod crustaceans (four species of crabs, seven species of shrimps) and fishes (24 species). Other typical estuarine taxons (mollusks, barnacles, polychaetes) were scarce or absent. Diversity increased seaward from 14 species near the estuary head to 29 species near the mouth. Three species of crustaceans and six of fishes were captured at all stations. Most abundant were the native prawn, Macrobrachium grandimanus, and mullet, Mugil cephalus. Perennially resident adults occurred among crustaceans and gobioid fishes; most other fishes were present as juveniles and sporadic adults. Comparisons with other data suggest that more than 50 species of native fishes may occur in Hawaiian estuaries, and that estuarine macrofaunal diversity on oceanic islands is much lower than on continents at similar latitudes.

  10. View of Oahu, Hawaii from STS-67 Endeavour

    1995-01-01

    This is an unusually full view of the island of Oahu in the Hawaiian chain of islands. Oahu's volcanic origins are hinted at by the volcanic crater at Diamond Head, clearly visible on the southern shore. The city of Honolulu stretches from Diamond Head to the inlet of Pearl Harbor. Honolulu's large international airport can be seen off the shore. The dense forestation of the highlands is visible below the cloud cover, and waves can be seen breaking along the northern shore where famous surfing beaches, such as Pipeline, are found.

  11. Tropical cyclone inundation potential on the Hawaiian Islands of Oahu and Kauai

    The lack of a continental shelf in steep volcanic islands leads to significant changes in tropical cyclone inundation potential, with wave setup and runup increasing in importance and wind driven surge decreasing when compared to more gently-sloped mainland regions. This is illustrated through high resolution modeling of waves, surge, and runup on the Hawaiian Islands of Oahu and Kauai. A series of hurricane waves and water levels were computed using the SWAN + ADCIRC models for a suite of 643 synthetic storm scenarios, while local wave runup was evaluated along a series of 1D transects using the phase-resolving model Bouss1D. Waves are found to be an extremely important component of the inundation, both from breaking wave forced increases in storm surge and also from wave runup over the relatively steep topography. This is clear in comparisons with debris lines left by Hurricane Iniki on the Island of Kauai, where runup penetration is much greater than still water inundation in most instances. The difference between steeply-sloping and gently-sloping topographies was demonstrated by recomputing Iniki with the same landfall location as Hurricane Katrina in Louisiana. Surge was greatly increased for the mild-slope Iniki-in-Louisiana case, while pure wind surge for Iniki-in-Kauai was very small. For the entire suite of storms, maxima on Kauai show predicted inundation largely confined to a narrow coastal strip, with few locations showing more than a few hundred meters of flooding from the shoreline. As expected, maximum flooded areas for the 643 storms were somewhat greater than the Iniki inundation. Oahu has significantly more low-lying land compared to Kauai, and consequently hypothetical tropical cyclone landfalls show much more widespread inundation. Under direct impact scenarios, there is the potential for much of Honolulu and most of Waikiki to be inundated, with both still water surge and wave runup contributing. Other regions of Oahu show inundation confined

  20. Coastal CO2 climatology of Oahu, Hawaii: Six years of high resolution time-series data

    NASA Astrophysics Data System (ADS)

    2014-12-01

    Six years of high resolution pCO2, water quality, and meteorological data were used to calculate air-sea CO2 fluxes on yearly, seasonal and monthly timescales, and relate the temporal and spatial variation in CO2 fluxes to meteorological events and land derived inputs. Three MAPCO2 buoys are deployed in coastal waters of Oahu as part of the NOAA/PMEL Carbon Program, that autonomously collects CO2 and water quality data at 3-hour intervals. The buoys are located on a backreef in Kaneohe Bay and two fringing reef sites on Oahu's south shore, the latter two in open ocean like conditions but with one also influenced by fluvial inputs. Data for this study were collected from June 2008 to July 2014. Mean pCO2 values at the Ala Wai, Kilo Nalu and CRIMP2 buoys were 396, 381 and 447μatm, respectively, with mean daily ranges of 51, 32 and 190 μatm, respectively. The daily range in pCO2 is largest at CRIMP2, reflecting a combination of higher primary production and respiration, vigorous calcification and longer water residence time within the barrier reef environment. Net annualized air-sea CO2 fluxes of the entire study period were 0.083, -0.014 and 1.167 mol C m-2 year-1 for Ala Wai, Kilo Nalu and CRIMP2, respectively. Positive values indicate a CO2 flux from the water to the atmosphere (source behavior), and negative values from the atmosphere to the water (sink behavior). This presentation will also discuss the effects physical and biogeochemical processes on the magnitude and variability of air-sea CO2 fluxes. We observe a negative correlation between CO2 flux and rainfall over monthly, seasonal, and annual timescales. This correlation however, can partly be explained by temperature, because increased rainfall is more common during the colder winter months. Nevertheless, rainfall affects CO2 fluxes, both by rain-induced nutrient and organic matter runoff, as well as the physical effect of raindrops on air-sea gas exchange and the dilution of the air-sea boundary layer

    Although the rice growth response to FACE (free-air CO2 enrichment) has been widely studied and is considered important within the scientific community, few studies have attempted to examine the effects of FACE on the yield of indica rice, which is typically the parent of indica hybrids in China. The effects of FACE on the yield, yield components, biomass, N uptake and leaf photosynthesis of Yangdao 6 Hao (an indica rice) in China were examined over 2 years. The grain yield increased over 30%, the panicle number increased 12.4% on average, and the spikelet number per panicle also showed an average increase of 8.2% at elevated CO2. FACE caused a significant enhancement in both the filled spikelet percentage (+5.9%) and the individual grain weight (+3.0%). Compared with three prior FACE studies on rice, a similar enhancement of yield in hybrid indica was shown under FACE, with much a higher value than for the japonica rice cultivar (approximately + 13%) because of indica's stronger sink generation and N uptake capacity, which help coordinate the C/N balance to avoid photosynthetic acclimation. The high enhancement of the indica rice yield under FACE holds promise for improved cultivar selection for future food security. PMID:26228872

    The Pearl Harbor aquifer is the most important freshwater resource on Oahu (Hawaii, U.S.A), providing water to nearly half a million people. Recent studies show that current water use is reaching or exceeding sustainable yield. Climate change and increasing resident and tourist populations are predicted to further stress the aquifer. The island has lost huge tracts of freshwater and estuarine wetlands since human settlement; the dependence of many endemic, endangered species on these wetlands, as well as ecosystem benefits from wetlands, link humans and wildlife through water management. After the collapse of the sugar industry on Oahu (mid-1990s), the Waiahole ditch--a massive stream diversion bringing water from the island's windward to the leeward side--became a hotly disputed resource. Commercial interests and traditional farmers have clashed over the water, which could also serve to support the Pearl Harbor aquifer. Considering competing interests, impending scarcity, and uncertain future conditions, how can groundwater be managed most effectively? Complex water networks like this are characterized by conflicts between stakeholders, coupled human-natural systems, and future uncertainty. The Water Diplomacy Framework offers a model for analyzing such complex issues by integrating multiple disciplinary perspectives, identifying intervention points, and proposing sustainable solutions. The Water Diplomacy Framework is a theory and practice of implementing adaptive water management for complex problems by shifting the discussion from 'allocation of water' to 'benefit from water resources'. This is accomplished through an interactive process that includes stakeholder input, joint fact finding, collaborative scenario development, and a negotiated approach to value creation. Presented here are the results of the initial steps in a long term project to resolve water limitations on Oahu. We developed a conceptual model of the Pearl Harbor Aquifer system and identified

  9. Hf-Nd isotope decoupling in the oceanic lithosphere: constraints from spinel peridotites from Oahu, Hawaii

    NASA Astrophysics Data System (ADS)

    2004-01-01

    We present a detailed geochemical investigation on the Hf, Nd and Sr isotope compositions and trace and major element contents of clinopyroxene mineral separates from spinel lherzolite xenoliths from the island of Oahu, Hawaii. These peridotites are believed to represent the depleted oceanic lithosphere beneath Oahu, which is a residue of a MORB-related melting event some 80-100 Ma ago at a mid-ocean ridge. Clinopyroxenes from peridotites from the Salt Lake Crater (SLC) show a large range of Hf isotopic compositions, from ɛHf=12.2 (similar to the Honolulu volcanics series) to extremely radiogenic, ɛHf=65, at nearly constant 143Nd/ 144Nd ratios ( ɛNd=7-8). None of these samples show any isotopic evidence for interaction with Koolau-type melts. A single xenolith from the Pali vent is the only sample with Hf and Nd isotopic compositions that falls within the MORB field. The Hf isotopes correlate positively with the degree of depletion in the clinopyroxene (e.g. increasing Mg#, Cr#, decreasing Ti and heavy REE contents), but also with increasing Zr and Hf depletions relative to the adjacent REE in a compatibility diagram. The Lu/Hf isotope systematics of the SLC clinopyroxenes define apparent ages of 500 Ma or older and these compositions cannot be explained by mixing between any type of Hawaiian melts and the depleted Pacific lithosphere. Metasomatism of an ancient (e.g. 1 Ga or older) depleted peridotite protolith can, in principle, explain these apparent ages and the Nd-Hf isotope decoupling, but requires that the most depleted samples were subject to the least amount of metasomatism. Alternatively, the combined isotope, trace and major element compositions of these clinopyroxenes are best described by metasomatism of the 80-100 Ma depleted oceanic lithosphere by melts products of extensive mantle-melt interaction between Honolulu Volcanics-type melts and the depleted lithosphere.

    1966-09-01

    Analysis of several well-documented specimens from each of the three volcanic series on Oahu gives the following mean ratios of Sr(87) to Sr(86): the Waianae series, 0.7030 +/- 0.00010 (sigma); the Koolau series, 0.70385+/- 0.00009 (sigma); and the Honolulu series, 0.7029 ++/- 0.00006 ( sigma). The mean ratio of Sr(87) to Sr(86) of the Koolau series specimens is significantly higher than the means of the other two series. With one exception, significant differences in Sr(87)/ Sr(86) within a series were not found, even though some large compositional differences existed. PMID:17754246

  12. A Physical Description of the Lithosphere and Seismic Low-Velocity Zone beneath Oahu: Perspectives from Hawaiian Mantle Xenoliths

    NASA Astrophysics Data System (ADS)

    Sen, G.; Bizimis, M.; Keshav, S.

    2003-12-01

    Mantle xenoliths provide a random sampling of a significant portion of the uppermost mantle beneath Oahu, including all of the lithosphere and the lithosphere-asthenosphere transition (LAT). We combine all the petrological, geochemical, and isotopic information on these xenoliths and evaluate existing models of the lithosphere and LAT beneath Oahu. The xenoliths are principally of two kinds - spinel peridotites and garenet clinopyroxenites; and they occur within the post-erosional Honolulu Volcanics (HV). Plagioclase peridotites are rare, and plagioclases in them are exotic, having crystallized from Koolau-like (enriched) magma. Trace element and Nd-Hf isotope ratios indicate recent metasomatic enrichment of the depleted peridotitic lithosphere by HV-like fluids. The pyroxenite suite xenoliths are dominantly composed of clinopyroxene and garnet with variable proportions of olivine, minor spinel and orthopyroxene, and rare phlogopite, carbonate, amphibole, and melt pockets. Phase equilibrium considerations indicate that these rocks form accumulates at the LAT and along the walls of fracture-conduits within the deep lithosphere. Nd-Sr isotope data on whole rocks and garnet and cpx separates show them to be depleted as well, partially overlapping with the host HV lavas and lithospheric spinel peridotite xenoliths. We view the Oahu lithosphere (below the crustal part) as follows: 20-30 km - depleted harzburgite with veins of plagioclase; 30 - 90 km - spinel peridotite layer (we model the vertical modal variation), 90 -130 km - cumulate garnet clinopyroxenites and "piclogites" with small amounts of (5 percent) intergranular H2O+CO2-rich fluids that may be of kimberlitic-carbonatite affinity. Our inferred compsition of the lithosphere and LAT are generally similar to geophysical models but predict a 200-250oC lower temperature within the LVZ beneath Oahu than the latter. In our model, Hawaiian plume-derived shield-stage magmas have little interaction with the lithosphere

  13. Pb Isotopic Evolution of Koolau Volcano (Oahu, Hawaii)

    2003-12-01

    High precision Pb isotopes in Hawaiian shield lavas have revealed the existence of source heterogeneities between volcanoes, as well as within a single volcano during its temporal evolution, e.g. Mauna Kea [1, 2]. The Koolau Scientific Drilling Project (KSDP) was initiated in order to evaluate the long-term evolution of Koolau volcano (Oahu), whose subaerial Makapuu stage lavas define the isotopically enriched endmember of Hawaiian shield lavas. We report Pb triple spike data on KSDP main shield-stage lavas (depth range: 304-632 mbsl) and post-erosional Honolulu volcanics. KSDP lavas show a small range of Pb isotopic compositions (206Pb/204Pb=18.02-18.15; 207Pb/204Pb=15.44-15.46; 208Pb/204Pb=37.82-37.87). Pb isotope ratios increase with depth until ˜450 m and then decrease again to a depth of 616 m. Superimposed on this "bell" trend, 206Pb/204Pb ratios oscillate at depth intervals of ˜10m. The Honolulu volcanics display, at a given 206Pb/204Pb ratio, similar 207Pb/204Pb but lower 208Pb/204Pb ratios than KSDP lavas. In 208Pb/204Pb-206Pb/204Pb space, KSDP and Honolulu lavas define two distinct linear arrays which converge at the radiogenic end. However, in 207Pb/204Pb-206Pb/204Pb space, KSDP and Honolulu lavas form a single array, with Honolulu lying at the radiogenic end of the array. While KSDP lavas have more radiogenic Pb isotopic compositions than Makapuu stage lavas [1], they show close resemblance to Nuuanu 1 and Nuuanu 2 landslide blocks [3]. The distinct Pb isotopic features of subaerial, main-shield and post-erosional lavas reflect compositional source changes during the growth of Koolau volcano. The mixing lines defined by KSDP and Honolulu lavas in 208Pb-206Pb space require the presence of three distinct Pb isotopic components. While the enriched "Koolau" component is predominantly sampled during the subaerial stage, its contribution during the main shield building stage has been waxing and waning. The radiogenic Pb endmember common to Honolulu and KSDP

    Three-dimensional modeling of groundwater flow and solute transport in the Pearl Harbor aquifer, southern Oahu, Hawaii, shows that the readjustment of the freshwater-saltwater transition zone takes a long time following changes in pumping, irrigation, or recharge in the aquifer system. It takes about 50-years for the transition zone to move 90% of the distance to its new steady position. Further, the Ghyben-Herzberg estimate of the freshwater/saltwater interface depth occurred between the 10 and 50% simulated seawater concentration contours in a complex manner during 100-years of the pumping history of the aquifer. Thus, it is not a good predictor of the depth of potable water. Pre-development recharge was used to simulate the 1880 freshwater-lens configuration. Historical pumpage and recharge distributions were used and the resulting freshwater-lens size and position were simulated through 1980. Simulations show that the transition zone moved upward and landward during the period simulated. Previous groundwater flow models for Oahu have been limited to areal models that simulate a sharp interface between freshwater and saltwater or solute-transport models that simulate a vertical aquifer section. The present model is based on the US Geological Survey's three-dimensional solute transport (3D SUTRA) computer code. Using several new tools for pre- and post-processing of model input and results have allowed easy model construction and unprecedented visualization of the freshwater lens and underlying transition zone in Hawaii's most developed aquifer. ??

  15. Geology and Stream Infiltration of North Halawa Valley, Oahu, Hawaii

    USGS Publications Warehouse

    1992-01-01

    A geohydrologic investigation of North Halawa Valley, Oahu, Hawaii, and its stream was undertaken in response to concern that runoff from the H-3 highway draining into the stream might seep into the ground and seriously contaminate potable water pumped at a nearby skimming well. North Halawa Stream flows over highly weathered alluvium or highly weathered basaltic basement for almost its entire course. Measurements of discharge at selected points along the stream indicate that infiltration occurs along some reaches. The infiltration of water from North Halawa Stream varies with season and stage. Water lost by the stream probably passes into and out of a perched aquifer in the alluvium of North Halawa Valley. Some of the water could pass from the alluvium to the basal aquifer from which the skimming well draws its water.

  16. Strontium Isotopic Variations in the Koolau Volcanic Series, Oahu, Hawaii: Results from KSDP Drill Core

    NASA Astrophysics Data System (ADS)

    Smith, M. M.; Depaolo, D. J.

    2005-12-01

    Surface samples of the Koolau tholeiite series, from the eastern side of the island of Oahu, Hawaii, have long been noted for their unusually high 87Sr/86Sr ratios (up to 0.7042) and other extreme geochemical parameters, as compared to both earlier and later Oahu lavas, values from other Hawaiian islands, and lavas from the Waianae volcano on west Oahu. It has been assumed that the geochemistry of the surface samples of Koolau applied to most of the volcano and that the extreme features were a relatively long-lived characteristic of the Hawaiian mantle plume at the time that the Koolau lavas were being erupted about 3 million years ago. The Koolau Scientific Drilling Project, which returned nearly continuous core from depths of 350 to 670 meters below sea level, provided an opportunity to probe deeper into the Koolau edifice (Haskins and Garcia, CMP, 147, 2004). We present new Sr isotope data on thirty whole rock samples from KSDP, which complement other isotopic data that have been reported recently (Salters and Blichert-Toft, submitted). The KSDP samples have variable, but generally significant, amounts of post-eruption weathering and hence the samples were strongly acid-leached before TIMS isotopic analysis in order to remove any seawater-derived strontium. The 87Sr/86Sr values in the core samples vary from values near 0.7040 at the top of the core to 0.7035 near the bottom. There is a general trend of increasing 87Sr/86Sr upsection as well as oscillations with peak-to-peak amplitude of 0.0003. The Sr isotope ratios correlate reasonably well with Nd and Hf isotope ratios. The data show that the Koolau surface samples are not representative of the volcano as a whole, and that the extreme geochemistry of the surface samples may represent only a minor component of the Hawaiian plume. The normal trend of Sr isotope ratios in the waning stages of shield building is from high values to low (as in Mauna Kea, Kohala, East Molokai and Haleakala). A trend toward higher

  6. The Heterogeneous Hawaiian Lithosphere: New Isotope Data From Kauai and Oahu Peridotites

    2005-12-01

    The Hf-Os isotope systematics of peridotites from Oahu suggest that the Hawaiian lithosphere is highly heterogeneous. We found that many Salt Lake Crater (SLC) peridotites vent are fragments of > 500Ma old recycled depleted lithosphere brought to the surface by the Hawaiian plume. In contrast, peridotites from the Pali vent have Hf-Os compositions appropriate for the 90 Ma old Pacific lithosphere. Here we present additional Sr-Nd isotope, major and trace element data from peridotites from the island of Kauai and from Salt Lake Crater and Pali vents on Oahu, in order to further constrain the extent and origin of the heterogeneity observed in the Hawaiian lithosphere. Two Kauai peridotites overlap the Koloa Volcanics post erosional lava compositions in Sr-Nd isotope space. A third Kauai peridotite has higher 87Sr/86Sr (0.70422) and lower 143Nd/144Nd (0.51291) than any published Kauai lavas and extends towards more radiogenic Sr (for a given Nd) than the Hawaiian lavas in general. This sample has depleted characteristics with high Mg# (0.925) and Cr# (0.311), and low HREE in cpx. It also has the highest La/Yb ratio and largest Ti depletions we have yet determined in Hawaiian peridotites. In contrast, three peridotites from SLC have less radiogenic 87Sr/86Sr (0.70316-0.70334), for a given 143Nd/144Nd (0.51285-0.51278) than all other analyzed peridotites and Hawaiian lavas. One peridotite straddles the proposed LoNd array thought to represent mixing between HIMU and EM-I mantle endmember components. In Hf-Nd space, this sample falls below the Hawaiian lava array having lower 176Hf/177Hf (0.28287) than even the most isotopically enriched Koolau lavas. Our new peridotite data show a much greater Sr and Nd isotope variability than previously observed, and support our conclusions based on the Hf-Os systematics for a highly heterogeneous lithosphere. The incompatible nature of Sr and Nd in peridotites makes them very susceptible to metasomatic overprint but the observed

    We report on an investigation of Montipora white syndrome (MWS), which is a coral disease reported from Hawaii, U.S.A., that results in tissue loss. Disease surveys of Montipora capitata within Kaneohe Bay (Oahu) found colonies that were affected by MWS on 9 reefs within 3 regions of Kaneohe Bay (south, central, north). Mean MWS prevalence ranged from 0.02 to 0.87% and average number of MWS cases per survey site ranged from 1 to 28 colonies. MWS prevalence and number of cases were significantly lower in the central region as compared to those in the north and south regions of Kaneohe Bay. There was a positive relationship between host abundance and MWS prevalence, and differences in host abundance between sites explained approximately 27% of the variation in MWS prevalence. Reefs in central Kaneohe Bay had lower M. capitata cover and lower MWS levels. MWS prevalence on reefs was neither significantly different between seasons (spring versus fall) nor among 57 tagged colonies that were monitored through time. MWS is a chronic and progressive disease causing M. capitata colonies to lose an average of 3.1% of live tissue mo(-1). Case fatality rate was 28% after 2 yr but recovery occurred in some colonies (32%). Manipulative experiments showed that the disease is acquired through direct contact. This is the first study to examine the dynamics of MWS within Hawaii, and our findings suggest that MWS has the potential to degrade Hawaii's reefs through time. PMID:20853736

    This assessment of groundwater-quality conditions of the Columbia Plateau, Snake River Plain, and Oahu for the period 1992-2010 is part of the U.S. Geological Survey's National Water Quality Assessment (NAWQA) program. It shows where, when, why, and how specific water-quality conditions occur in groundwater of the three study areas and yields science-based implications for assessing and managing the quality of these water resources. The primary aquifers in the Columbia Plateau, Snake River Plain, and Oahu are mostly composed of fractured basalt, which makes their hydrology and geochemistry similar. In spite of the hydrogeologic similarities, there are climatic differences that affect the agricultural practices overlying the aquifers, which in turn affect the groundwater quality. Understanding groundwater-quality conditions and the natural and human factors that control groundwater quality is important because of the implications to human health, the sustainability of rural agricultural economies, and the substantial costs associated with land and water management, conservation, and regulation. The principal regional aquifers of the Columbia Plateau, Snake River Plain, and Oahu are highly vulnerable to contamination by chemicals applied at the land surface; essentially, they are as vulnerable as many shallow surficial aquifers elsewhere. The permeable and largely unconfined character of principal aquifers in the Columbia Plateau, Snake River Plain, and Oahu allow water and chemicals to infiltrate to the water table despite depths to water commonly in the hundreds of feet. The aquifers are essentially unconfined over large areas, having few extensive clay layers to impede infiltration through permeable volcanic rock and alluvial sediments. Agriculture is intensive in all three study areas, and heavy irrigation has imposed large artificial flows of irrigation recharge that rival or exceed natural recharge rates. Fertilizers and pesticides applied at land surface are

    2011-01-01

    This report describes the results of a pilot forest bird survey and a consequent forest bird monitoring protocol that was developed for the O'ahu Forest National Wildlife Refuge, O'ahu Island, Hawai'i. The pilot survey was conducted to inform aspects of the monitoring protocol and to provide a baseline with which to compare future surveys on the Refuge. The protocol was developed in an adaptive management framework to track bird distribution and abundance and to meet the strategic habitat conservation requirements of the Refuge. Funding for this research was provided through a Science Support Partnership grant sponsored jointly by the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service (USFWS).

    The meeting began with presentations by the facilitator, Mr. Spiegel, and Dr. Lewis, the representative from DOE. The facilitator introduced those on the podium. He then described the general structure of the meeting and its purpose: to hear the issues and concerns of those present regarding the proposed Hawaiian Geothermal Project. He described his role as assuring the impartiality and fairness of the meeting. Dr. Lewis of DOE further defined the scope of the project, introduced members of the EIS team, and briefly described the EIS process. Ninety percent of those presenting expressed concern about the potential impacts of the HGP to the environment. They asked that the EIS investigate the impacts of 1.he HGP on quality of air, water and soils, flora and fauna, land, socioeconomics, religion and culture. Seventy percent of the commenters want the EIS to investigate the impacts of all components of the HGP (eg. generation facilities, pipes, roads, drill pads, transmission corridors, and cable) on terrestrial ecosystems (e.g. the rainforest), threatened and endangered species, species diversity, species used for ritual or medicinal purposes, and climate stability. The EIS should address the effects of segmentation of habitat, introduction of exotic species, acid rain, herbicides, and enhanced fire danger. It should consider the entire Kilauea East Rift Zone when studying the impacts of HGP on the ecology of the Puna District. Of importance is the interrelationship between the lava, the biota of the region, and the regeneration that occurs following an eruption. DOE should examine the impacts of the network of roads that would be constructed for the HGP. Roads may serve as barriers that segment habitats, prevent regeneration and natural spread of biota, or serve as conduits for introduction of exotic species or for mobilization of herbicides. They may enhance the potential for logging or collecting of endangered native species. The EIS should determine the impacts

    Six biological/chemical cruises at two stations off Kahe Point, Oahu, Hawaii which took place between May 1980 and May 1981 are detailed. The objective was to evaluate the variability of physical, chemical, and biological variables within a potential OTEC siting area over a yearly cycle. The minimum ..delta..T observed between surface waters and 700 m was about 19/sup 0/C. Nutrient concentrations showed typical profiles with the largest variability occurring at depth. Strong positive correlations exist between nitrate and both phosphate and silicate. Both dissolved organic nitrogen and phosphorus are highest in the surface mixed layer, decline through the nutricline, and become relatively constant near 900 m. Nutrient concentrations also showed significant variation with time of year and between stations in both near surface and deep water. The vertical distribution of chlorophyll a showed a maximum between 55 m and 120 m. The euphotic zone extended to about 130 m. Total biomass concentrations were uniform in the upper 80 m declining with depth. Primary productivity was uniform with depth down to 90 m and then declined. Phytoplankton measurements varied mainly with depth and time of year. Zooplankton biomass and number were higher in surface waters and decreased with depth. As with nutrient and phytoplankton data, zooplankton variability was greatest with depth. However, zooplankton measurements showed significant differences between day and night. Additionally, small but significant variations due to time of year and station-to-station were observed. Zooplankton taxonomic analyses from these two sites were consistent with analyses from other tropical sites.

    Public concern over the discharge of primarily treated sewage by two offshore outfalls in Mamala Bay, Oahu, prompted a multidisciplinary study to determine the impact of such activities on the water quality in the bay and at adjacent recreational beaches. As part of this study, we determined the abundance of coliphage as an indicator of fecal pollution along with total viral direct counts and phages infective for Vibrio parahaemoltyicus 16 at stations in Mamala Bay in four quarterly samplings over 13 months. Coliphage (< 1 to 1.2 x 10(3)/liter) were found during each quarterly sampling along an offshore transect to the Sand Island waste treatment facility outfall. The nonpoint coastal stations (Pearl Harbor, Ala Wai Canal, and Ke'ehi Lagoon) had high levels of coliphage during the storm event sampling in February 1994 but much lower levels or none when sampled during dry weather. Coliphage were absent at all samplings at Waikiki Beach and at the control station off Diamond Head. Viral direct counts in eutrophic coastal stations (Pearl Harbor, Ke'ehi Lagoon, Ala Moana Beach, and Ala Wai canal) averaged 10(9)/liter, while counts at offshore stations ranged from 9 x 10(7) to 1 x 10(9) viruses/liter, values similar to those for other marine environments. Vibriophage were found mainly in eutrophic coastal environments (Ala Wai Canal, Pearl Harbor, and Ke'ehi Lagoon) and at the Sand Island Transect stations D1 and D2. The greatest abundance was found during the storm event (February 1994) sampling. These results suggest that the Sand Island outfall influenced the water quality of the immediate surrounding waters but had little effect on the quality of the recreational beaches. Nonpoint discharge sources appeared to be more important in the distribution of fecal indicators in the coastal zone. PMID:9065272

    Two 40 MWe Ocean Thermal Energy Conversion (OTEC) Pilot Plant programs are in the initial phase of development near Kahe Point, Oahu, Hawaii. The two options being examined are: (1) a shelf-seated artificial island, connected via a causeway to Oahu, using stainless steel heat exchangers, with the thermal resource enhanced by effluent from a near-by power plant, ammonia working fluid and biocide (chlorine) cleaning; and (2) a shelf mount tower 1 mile off shore using submerged aluminum heat exchangers, R-22 working fluid, and slurry cleaning with biocide (chlorine) backup. Environmental Technical Requirements are described including: siting criteria; environmental design, and operational criteria; thermal resource evaluation and variability; physical, chemical, and biological data requirements; and regulatory requirements. Due to siting, design, and operational differences the proposed two pilot plant options have individual environmental monitoring criteria and requirements. Due to the close spatial proximity of the proposed pilot plants they also have required environmental data which are common to both.

    Concentrations of aerosolic quartz and 137Cs were used to estimate rates of hillslope soil erosion during 1990-91 in the North Halawa Valley on the island of Oahu, Hawaii. Fluvial transport of quartz was estimated to be 6.1 Mg in 1990 and 14.9 Mg in 1991. Fluvial transport of 137Cs from North Halawa Valley was estimated to be 1.29 ?? 109 pCi in 1991. Results were used with quartz contents, 137Cs activities, and bulk densities of hillslope soils to compute rates of basinwide hillslope soil erosion ranging from 0.1 to 0.3 mm yr-1. These rates are within the range of previous estimates of denudation computed for drainage basins on Oahu. The aerosol-concentration approach, therefore, is a useful method for assessing basinwide soil erosion.

  6. An analysis of the magnitude and frequency of floods on Oahu, Hawaii

    1980-01-01

    An analysis of available peak-flow data for the island of Oahu, Hawaii, was made by using multiple regression techniques which related flood-frequency data to basin and climatic characteristics for 74 gaging stations on Oahu. In the analysis, several different groupings of stations were investigated, including divisions by geographic location and size of drainage area. The grouping consisting of two leeward divisions and one windward division produced the best results. Drainage basins ranged in area from 0.03 to 45.7 square miles. Equations relating flood magnitudes of selected frequencies to basin characteristics were developed for the three divisions of Oahu. These equations can be used to estimate the magnitude and frequency of floods for any site, gaged or ungaged, for any desired recurrence interval from 2 to 100 years. Data on basin characteristics, flood magnitudes for various recurrence intervals from individual station-frequency curves, and computed flood magnitudes by use of the regression equation are tabulated to provide the needed data.

    Progressive thermal treatment has been used to investigate the anisotropy of magnetic susceptibility (AMS) of a wide range of lithologies. Initial results on e.g., red sandstones, glacial tillites, granites and gneisses showed that laboratory stepwise heating resulted in thermal enhancement of AMS, showing the potential of thermal treatment in studying weak AMS and masked or cryptic fabrics. Studies have however shown that heating induced changes in AMS may be more complex that simple enhancement of the magnetic fabric In general, thermal induced magneto-mineralogical alterations are complex and not well understood, and further investigation of heating induced effects in mineralogy, grain size and texture systematically investigated for different lithologies is needed. For our experiment we have used a suite of samples from eight basaltic dikes from the Kappa Quarry, Koolau volcanic range in Oahu, Hawaii. The AMS fabric was determined as part of a study to investigate the influence of hydrothermal alteration by Krasa and Herrero-Bervera (2005). They found that hydrothermal alteration changes the bulk susceptibility and anisotropy degree, but AMS ellipsoid principal axes are not affected. Since hydrothermal alteration transforms the primary Ti-poor titanomagnetites into granular intergrowths of titanomagnetites, titanomaghemite and hematite, and that samples show varying degrees of alteration, the samples react differently to laboratory stepwise heating permitting study of thermal effects on the magnetic mineralogy, and AMS parameters and principal susceptibility axes. Further, thermal treatment results in fabric enhancement with reduced axial scatter associated with weak bulk susceptibilities and anisotropy degrees in the dikes. For the AMS experiment samples were heated progressively to temperatures up to 400° C or 560° C and the AMS measured after each step. AMS parameters and bulk susceptibility show changes with increasing temperature while the AMS

  8. Water in the Oceanic Lithosphere: Salt Lake Crater Xenoliths, Oahu, Hawaii

    Water can be present in nominally anhydrous minerals of peridotites in the form of hydrogen bonded to structural oxygen. Such water in the oceanic upper mantle could have a significant effect on its physical and chemical properties. However, the water content of the MORB source has been inferred indirectly from the compositions of basalts. Direct determinations on abyssal peridotites are scarce because they have been heavily hydrothermally altered. Here we present the first water analyses of minerals from spinel peridotite xenoliths of Salt Lake Crater, Oahu, Hawaii, which are exceptionally fresh. These peridotites are thought to represent fragments of the Pacific oceanic lithosphere that was refertilized by alkalic Hawaiian melts. A few have unradiogenic Os and radiogenic Hf isotopes and may be fragments of an ancient (2 Ga) depleted and recycled lithosphere. Water contents in olivine (Ol), orthopyroxene (Opx), and clinopyroxene (Cpx) were determined by FTIR spectrometry. Preliminary H_{2}O contents show ranges of 8-10 ppm for Ol, 151-277 ppm for Opx, and 337-603 ppm for Cpx. Reconstructed bulk rock H_{2}O contents range from 88-131 ppm overlapping estimates for the MORB source. Water contents between Ol minerals of the same xenolith are heterogeneous and individual OH infrared bands vary within a mineral with lower 3230 cm^{-1} and higher 3650-3400 cm^{-1} band heights from core to edge. This observation suggests disturbance of the hydrogen in Ol likely occurring during xenolith entrainment to the surface. Pyroxene water contents are higher than most water contents in pyroxenes from continental peridotite xenoliths and higher than those of abyssal peridotites. Cpx water contents decrease with increasing degree of depletion (e.g. increasing Fo in Ol and Cr# in spinel) consistent with an incompatible behavior of water. However Cpx water contents also show a positive correlation with LREE/HREE ratios and LREE concentrations consistent with refertilization. Opx water

    A 16 MHz high-frequency Doppler radio (HFDR) deployed on the south shore of Oahu (Hawaii) detected oscillatory radial currents following the arrival of the 2011 Tohoku tsunami. The observations over a two-dimensional area provided an opportunity for intercomparison with the spatial patterns of currents and the resonant modes predicted by a nonhydrostatic model. Over the 50 m deep Penguin Bank, extending west from Molokai, the observed currents are intensified in two areas: 43 min period currents of 0.27 m s-1 lasting 6 h are observed on the south part of the bank, while 27 min period currents of 0.14 m s-1 lasting 2 h are observed on the north. The spatial EOFs suggest that standing full-waves and 3/2 waves formed over the bank. Modeled currents over Penguin Bank are similar to the observations but their north-south asymmetry is less pronounced than observed. Nearshore, observed alongshore currents showed long-period oscillations of 43 min that stretched along the entire coastline, while modeled currents show strong evidence for edge waves. EOF analysis of the nearshore signal suggests that the HFDR and model reveal different processes. The discrepancy might be attributed to the fact that both the Penguin Bank and nearshore observations are limited by HFDR sensitivity to azimuthal sidelobe contamination and decreased angular resolution at high steering angles.

    Thorium-230 ages of emergent marine deposits on Oahu, Hawaii, have a uniform distribution of ages from {approximately}114,000 to {approximately}131,000 years, indicating a duration for the last interglacial sea-level high stand of {approximately}17,000 years, in contrast to a duration of {approximately}8000 years inferred from the orbitally tuned marine oxygen isotope record. Sea level on Oahu rose to {>=}1 to 2 meters higher than present by 131,000 years ago or {approximately}6000 years earlier than inferred from the marine record. Although the latter record suggests a shift back to glacial conditions beginning at {approximately}119,000 years ago, the Oahu coral ages indicate a near present sea level until {approximately}114,000 years ago.

    2003-12-01

    In order to investigate the volcanic evolution of the Koolau Volcano (one of the volcanoes that make up the island of Oahu) and the short-term behavior of the geomagnetic field, we have sampled a long volcanic section located on the butressed flank of the Koolau Volcano within the Halawa Valley. Prior paleomagnetic and radiometric investigations of the Koolau Volcano have reported excursional directions within the Koolau Volcanic Series (Site F of Doell and Dalrymple, 1973). The composition of the (100 m) thick sequence of lava flows, easy access, and close geographical proximity to dated flows made these excellent candidates for a detailed paleomagnetic analysis. The flows sampled were bounded between the current K-Ar dates obtained from adjacent lava flows (1.9 ñ 0.1 Ma to 2.2 ñ 0.1 Ma). At least eight samples were taken of each analyzed flow. Specimens of each sample were stepwise demagnetized by both alternating field (5mT to 100mT) and thermal (from 28oC to 575-650oC) methods, and the mean directions were obtained by principal component analysis. All samples have indicated a strong and stable ChRM trending towards the origin based on no less than seven to nine steps, with thermal and AF results agreeing to a very high degree. Low field susceptibility versus temperature (k-T) analyses were conducted for individual lava flows, and the majority of them show reversible curves. Curie point determinations revealed a temperature close to or equal to 580oC, indicative of almost pure magnetite for most of the flows. The mean directions of magnetization of the entire section sampled indicate that about 10 m of the section are characterized by excursional directions. The calculated corresponding VGPs are located at equatorial latitudes and on the central and south part of Africa with a few of the other ones close to the west part of Australia. These excursional directions place important constraints to the entire volcanic evolution of the Koolau edifice since they

    At Makapuu Point (SE Oahu, Hawaii) three lava flows over-lie each other in a 2.3-m-thick section. Although being emplaced on identical slopes, at identical distances from the likely source (the SE rift zone of Koolau volcano), and stack up one upon the other, the three flows are entirely different. The base of the sequence comprises pahoehoe, the middle section comprises a single 'a'a flow unit, and the top comprises a flow that is transitional between pahoehoe and 'a'a. We have carried out macroscopic field studies of this sequence, supported by laboratory-based microscopic studies of the vesicle and crystal populations to (1) define the differences between these three flow types, and (2) determine what makes a lava of the same composition emplaced at the same location so different in morphology. The pahoehoe forms a 0.5-m-thick pile of seven lobes. These have densities of 1.25-1.75 g m-3 which, using a dense rock value of 2.65 g m-3, yield vesicularities of 34-53 %. Macroscopically, the vesicles show a classic S-Type pahoehoe distribution, with a population of smaller spherical bubbles at each lobe periphery, and larger spherical bubbles towards each lobe center. The 'a'a flow comprises a surface and basal clinker, 0.42 and 0.23 m thick, respectively, separated by a 0.58-m-thick massive core. Densities are 1.57-2.09 g m-3 giving vesicularities of 21-41 %. Locally, the direction of shear (as indicated by the long axis orientation of vesicles) opens around shear-parting structures internal to the core. Finally, the 0.5-m-thick transitional flow has 0.08-0.42 m thick upper and lower zones with paheohoe characteristics, and a 0.17-m-thick core with 'a'a characteristics. The base has a population of small, spherical, bubbles and has a density of 1.63 g m-3 to give a vesicularity of 38 %. This basal layer also toes into the underlying 'a'a clinker. This lower zone is separated from the core by a sharp contact, with the core containing sheared vesicles and having a

    Tropical wetlands constitute a major source of methane, an atmospheric greenhouse gas. Net methane emission in freshwater settings is the result of organic matter decomposition under anaerobic conditions modulated by aerobic methane oxidation and is thus also an indicator of wetland ecosystem processes. This study is monitoring the methane flux from the Ka`au crater wetland on the island of Oahu (Hawaii) and correlating it with environmental parameters such as precipitation and sunlight. We are obtaining precipitation, Photosynthetic Active Radiation (PAR), and water table level data with data loggers and are correlating these data with static chamber methane flux measurements and measurements of soil methane production potential. Additionally, our research is studying the effects of changes in vegetation type, i.e., of the invasive strawberry guava tree (Psidium Cattleianum) on the wetland methane emissions. Changes in soil chemistry and in the transport of gases by roots that accompany such vegetation change are a potential driver of methane flux modifications that have not been previously examined. Strawberry guava forms dense mats of surface roots that may change soil gas exchange and prolific fruiting may raise the soil organic content. We collected soil samples along a 30 meter transect that extends through two vegetation patterns; the strawberry guava canopy and the sedge meadow (Cladium Leptostachyum). Samples were incubated for 24 hours to estimate their methane generation potential. Our preliminary results show that methane generation potential is greater under the strawberry guava canopy. However, 2 of the 15 samples collected in the sedge meadow section of the transect did not match this pattern. Soil organic carbon content is slightly higher in the strawberry guava than in the sedge. We recorded a 90% decrease in methane generation potential in sedge meadow soils during a dry period relative to a wet period 2 months earlier. We propose that this change

  15. Sedimentology of rocky shorelines: 2. Shoreline megaclasts on the north shore of Oahu, Hawaii—origins and history

    Limestone megaclasts, up to 96 t in weight, rest on a coastal rock platform near Sunset Beach on the north shore of Oahu, Hawaii. They occur in seaward-dipping, imbricate clusters and as solitary clasts. The rock platform is subject to large swell waves and very large waves associated with winter storms and tsunami. A series of photographs, covering the period from ca. 1905 to 1996, show episodic rearrangement of megaclasts on the platform and the appearance of new megaclasts near the platform edge. The largest solitary megaclast (ca. 96 t) was emplaced on the platform between 1940 and 1950, possibly by the 1946 Aleutian tsunami and has moved twice since then in ca. 30-m jumps along two different trajectories. Larger clasts have been broken from the platform edge and emplaced on the platform only by very large wave events, whereas formation and movement of smaller tabular, clasts (ca. 30-40 t) appear to be a continuously ongoing process on the surface of the rock platform. Partial detachment of clasts by marine erosion processes along joints and cracks in the limestone bedrock facilitates their complete detachment from both the platform edge and platform surface. The larger numbers of megaclasts emplaced on the north and northwest sectors of the platform relative to other sectors are attributed to exertion of maximum wave power on these sectors due to a combination of steep slope and ramp-like submarine topography.

    Objectives To determine the feasibility of a resident physician-based, culturally appropriate method of decreasing the disease burden of Type 2 Diabetes Mellitus (DM2) in a group of Pacific Islanders, Marshallese living in Hawai’i. Methods Thirty one Marshallese with diabetes who live on the island of Oahu, Hawaii were recruited. Baseline health status of the participants was characterized. Health parameters included HgbA1c, random blood sugar (RBS), lipid panels, body mass index (BMI), blood pressure, and medical history, along with qualitative information. A focus group was held with participants prior to beginning the curriculum to determine cultural views on diabetes, health, treatment, and to identify potential obstacles to health improvement. A DM2 educational curriculum culturally relevant to Marshallese populations was then started, including instruction in lifestyle modification, adherence to medication regimens, and planned quarterly assessment of health improvement. Results Baseline quantitative analysis revealed Marshallese with diabetes to be obese and hyperglycemic, with average BMI of 30 kg/m2, RBS of 285, and HgbA1c of 9.3. Qualitative analysis revealed that nearly half the participants admitted to symptoms of severe hyperglycemia. The initial focus group had a substantial turnout. Attendance rapidly declined, becoming so low that classes were eventually terminated. However, in two participants who attended more than three classes there was evidence of major improvements in HgbA1c, cholesterol, and qualitative markers, which were sustained after one year. Conclusions This pilot study of Marshallese with diabetes on Oahu showed that the majority had poor glycemic control with secondary co-morbid conditions. Although many barriers exist for successful implementation of a diabetes health improvement project in this group, the groundwork for translation of this project to the Republic of Marshall Islands (RMI) has been laid; curriculum translation and

    This Open-File Report presents data and derivative products from an investigation of carbonate sediment deposits on the reef front in four areas around the island of Oahu, Hawaii - in Kailua Bay off Oahu's windward (east) side, off the leeward (west) coast from Makua to Kahe Point, off the north coast from Waimea to Camp Erdman, and off the south coast around Waikiki (Figure 1). The primary purpose of the investigation was to assess the resource potential of the deposits, particularly as a source of sand for beach nourishment. This work builds on previous studies by researchers from the University of Hawaii (Moberly et al., 1975; Coulbourn et al., 1988; Barry, 1995). The field program included collection of high-resolution acoustic-reflection profiles and vibracore sediment samples in Kailua Bay and off the leeward and north coasts. In a related project, in collaboration with the Hawaii State Department of Land and Natural Resources and the University of Hawaii, sidescan images and vibracores were collected in the Halekulani channel and on the adjacent Makua Terrace off Waikiki along the south coast.

    Spatial disorientation (SD) is one of the most severe causative factors in aviation accidents. We analyzed the reported SD episodes to evaluate the characteristics of severe SD in fighter pilots. Three hundred seventeen cases (95.5%) of 332 total valid cases experienced SD, and the ratio of night and day SD experiences (52.7% vs. 47.3%) (p < 0.05) shows a clear prevalence of night SD events. The severity of SD episodes at night (2.23 +/- 1.09) was higher than at day (1.89 +/- 1.04) (p < 0.01). In addition, the severity of visual illusions was significantly higher at night. A significant difference was found for meteorological conditions, such as visual meteorological conditions (VMC), instrument meteorological conditions (IMC) and VMC-IMC (VI) transition, among times of days. In conclusion, the severity of the SD episodes was higher at night. This may be due to an increase in visual severe SD episodes at night. PMID:19585777

    A survey of endangered waterbirds on Maui and Oahu was conducted during August and September 1993 to identify potential waterbird habitats within the general area of the proposed Hawaii Geothermal Project transmission corridor and to assess the potential impacts to endangered waterbird of installing and operating a high voltage transmission line from the Island of Hawaii to the islands of Oahu and Maui. Annual waterbird survey information and other literature containing information on specific wetland sites were summarized. Literature describing impacts of overhead transmission lines on birds was used to evaluate potential impacts of the proposed project on endangered waterbirds, resident wading birds, and migratory shorebirds and waterfowl. On Oahu, five wetland habitats supporting endangered Hawaiian waterbirds were identified within 2.5 miles of the proposed transmission line corridor. On Maui, three wetland habitats supporting endangered Hawaiian waterbirds were identified within the general area of the proposed transmission line corridor. Several of the wetlands identified on Oahu and Maui also supported resident wading birds and migratory shorebirds and waterfowl. Endangered waterbirds, resident wading birds, and migratory birds may collide with the proposed transmission lines wires. The frequency and numbers of bird collisions is expected to be greater on Oahu than on Maui because more wetland habitat exists and greater numbers of birds occur in the project area on Oahu. In addition, the endangered Hawaiian goose and the endangered Hawaiian petrel may be impacted by the proposed segment of the Hawaii Geothermal Project transmission line on Maui.

    This report presents the results of the preliminary assessment (PA) conducted by Argonne National Laboratory at the Hawaii Army National Guard (HIARNG) property near Pearl City, Oahu, Hawaii. Preliminary assessments of federal facilities are being conducted to compile the information necessary for completing preremedial activities and to provide a basis for establishing corrective actions in response to releases of hazardous substances. The principal objective of the PA is to characterize the site accurately and determine the need for further action by examining site activities, quantities of hazardous substances present, and potential pathways by which contamination could affect public health and the environment. This PA satisfies, for the Waiawa Gulch property, phase I of the Department of Defense Installation Restoration Program (IRP).

    Oki, Delwyn S.; Souza, William R.; Bolke, Edward L.; Bauer, Glenn R.

    The coastal aquifer system of southern Oahu, Hawaii, USA, consists of highly permeable volcanic aquifers overlain by weathered volcanic rocks and interbedded marine and terrestrial sediments of both high and low permeability. The weathered volcanic rocks and sediments are collectively known as caprock, because they impede the free discharge of groundwater from the underlying volcanic aquifers. A cross-sectional groundwater flow and transport model was used to evaluate the hydrogeologic controls on the regional flow system in southwestern Oahu. Controls considered were: (a) overall caprock hydraulic conductivity; and (b) stratigraphic variations of hydraulic conductivity in the caprock. Within the caprock, variations in hydraulic conductivity, caused by stratigraphy or discontinuities of the stratigraphic units, are a major control on the direction of groundwater flow and the distribution of water levels and salinity. Results of cross-sectional modeling confirm the general groundwater flow pattern that would be expected in a layered coastal system. Groundwater flow is: (a) predominantly upward in the low-permeability sedimentary units; and (b) predominantly horizontal in the high-permeability sedimentary units.

    2009-01-01

    In 2006-07, the U.S. Geological Survey (USGS) Pacific Islands Water Science Center (PIWSC), in cooperation with the Hawai'i Department of Health (HDOH), conducted a pilot study as a participant in the U.S. Environmental Protection Agency's (USEPA) Wadeable Streams Assessment (WSA) program. Forty randomly selected sites on perennial streams on O'ahu, Hawai'i, were surveyed for habitat characteristics, water chemistry, and benthic macroinvertebrate assemblages. Of the original sampling frame of approximately 505.2 miles of perennial stream, roughly 96.7 +or- 30.7 miles were found to be nonperennial or estuarine and another 200.5 +or- 64.7 miles were judged to be inaccessible. The scope of this report presents an assessment of the remaining 208 +or- 57.6 miles of accessible, wadeable, perennial stream length on O'ahu. Benthic macroinvertebrate assemblages were used to determine the ecological condition at each site. Components of the benthic macroinvertebrate assemblages were assessed using the multimetric Preliminary-Hawaiian Benthic Index of Biotic Integrity (P-HBIBI) developed by Wolff (2005). Based on the P-HBIBI scores, an estimated 5.8 +or- 5.8 percent of the island's total stream length is in most disturbed condition, 56 +or- 13.5 percent is in intermediately disturbed condition, and 38.2 +or- 13.2 percent is in least disturbed condition. Windward O'ahu had the highest percentage of stream length in least disturbed biological condition at 56.7 +or- 20.8 percent. Using the relative abundance of insects, one of the core metrics that make up the P-HBIBI, 43.4 +or- 14.2 percent of the islandwide stream length was classified in the most disturbed condition - 52 +or- 31.2 percent of the Honolulu region stream length and 51.4 +or- 23.3 percent of the windward O'ahu stream length. An analysis of total nitrogen (N) estimated approximately 41.1 +or- 13.7 percent of the stream length on O'ahu was in most disturbed condition. Regionally, the Honolulu region had the largest

  14. Tunnels and dikes of the Koolau Range, Oahu, Hawaii, and their effect on storage depletion and movement of ground water

    USGS Publications Warehouse

    Hirashima, George Tokusuke

    1971-01-01

    Ground water impounded by dikes in the Koolau Range is a major source of water for the island of Oahu, Hawaii, and many tunnels have been bored into the range to develop it. All water-development tunnels, except Waihee tunnel, have depleted storage in the rocks they penetrate and are now discharging at rates that are but fractions of the rates possible at full storage. Rocks above the floor of the water-development part of Waihee tunnel have never been completely dewatered, and storage can be manipulated by regulating outflow. Thus, storage for this tunnel can be increased during periods of low demand and discharged at high rates during periods of high demand. A measure of the rate of drainage or depletion of storage is the recession constant b in the recession-curve equation Qt=Q0e-b t. The higher the value of b, the faster water can be drawn from storage or returned to storage through artificial recharge. Mathematical analysis of the flow-recession curve of Waihee tunnel shows that (1) its recession constant is 0.00401, (2) net storage (exclusive of recharge) is 2,200 million gallons (6,800 acre-feet), and (8) initial discharge from full storage would be about 19 million gallons per day. Analysis of flow-recession curves for Waiahole ditch tunnel (main bore) and Haiku tunnel shows that these tunnels have drainage characteristics that are similar to those of Waihee tunnel. The composite recession constant computed for the four tunnels north of Waiahole is about one-third as large as that computed for the Waiahole ditch tunnel (main bore) and the tunnels to the south. The difference is due to an abrupt change in spacing of dikes north of Waiahole. At and south of Waiahole Stream, dikes are spaced tens or hundreds of feet apart; north of Waiahole, they are spaced inches or a few feet apart. Storage could be restored by bulkheading at the controlling dike or dikes after an analysis is made of the flow-recession curve for each tunnel. Such analyses will show which

    The Koolau dyke swarms, exposed within the Kailua embayment on the northeastern side of Oahu, have been interpreted as feeders to rift zones in the Koolau volcano, analagous to the rift zones of Kilauea volcano (Walker, 1987), that developed prior to the giant Nuuanu lateral collapse at about 2.0 Ma. Systematic determination of cross-cutting relationships between Koolau dykes has proved difficult because of dense vegetation and rapid weathering in the humid tropical climate of windward Oahu. For this study we have concentrated on exposures of the dykes in the large (450 m wide and 200m deep) Kapa'a quarry, about 3 km NE of the near vertical Nuuanu Pali escarpment. Kapa'a quarry was chosen for this study because it has large, freshly exposed sections nearly perpendicular to the dyke swarm trend in hydrothermally altered but largely unweathered rocks. The hydrothermal alteration indicates that the dykes exposed in the quarry were emplaced well below a high water table resulting from trapping of water between dykes: this high water table may have played a part in the eventual collapse. The excellent exposure at Kapa'a allows systematic, accurate determination of structural data and cross-cutting relationships for every dyke in the measured sections. These data were collected for 171 dykes, of which 10 dykes have so far been sampled for palaeomagnetic analysis (i.e remanence and petrofabrics). Most dykes at Kapa'a dip steeply, from around 70 degrees SW (away from the unstable flank of the volcano) through vertical to 50 degrees NE (towards the unstable flank). NE dipping dykes are more abundant overall. Groups of SW - dipping dykes alternate with groups of subvertical to NE - dipping dykes, suggesting a quasi-periodic alternation of the stress regime within the Koolau volcano. Dyke dilations were typically subhorizontal. A final group of dykes, cross-cutting all the others, dip from 50 degrees NE to as little as 35 degrees NE, and dilated in a steeply SW - plunging

    Shallow coral reefs are extensively studied but, although scleractinian corals have been recorded to 165 m, little is known about other mesophotic coral reef ecosystem (MCE) inhabitants. Brachyuran crabs fill many ecological and trophic niches on reefs, making them ideal candidates for evaluating species composition among depths to ask whether MCEs host the same communities as shallower reef communities that have been well studied. Here we deployed autonomous reef monitoring structures for 2 yr on the south shore of O`ahu along a depth gradient (12, 30, 60, and 90 m) to sample and assess brachyuran crab communities. A total of 663 brachyuran crabs representing 69 morphospecies (16 families) were found. Community composition was not significantly different within depths, but was highly stratified by depth. Each depth was distinct, but the 30 and 60 m depths were least dissimilar from one another. We show that deeper reefs host significantly different brachyuran communities, and at much lower total abundance, than shallow reefs in Hawai`i, with 4-27 unique morphospecies per depth and only 3 of 69 morphospecies (~4 %) occurring across the entire depth range sampled.

  17. The Importance of Sampling Strategies on AMS Determination of Dykes II. Further Examples from the Kapaa Quarry, Koolau Volcano, Oahu, Hawaii

    2012-12-01

    Recent work has suggested the convenience of dyke sampling along several profiles parallel and perpendicular to its walls to increase the probability of determining a geologically significant magma flow direction using anisotropy of magnetic susceptibility (AMS) measurements. For this work, we have resampled in great detail some dykes from the Kapaa Quarry, Koolau Volcano in Oahu Hawaii, comparing the results of a more detailed sampling scheme with those obtained previously with a traditional sampling scheme. In addition to the AMS results we will show magnetic properties, including magnetic grain sizes, Curie points and AMS measured at two different frequencies on a new MFK1-FA Spinner Kappabridge. Our results thus far provide further empirical evidence supporting the occurrence of a definite cyclic fabric acquisition during the emplacement of at least some of the dykes. This cyclic behavior can be captured using the new sampling scheme, but might be easily overlooked if the simple, more traditional sampling scheme is used. Consequently, previous claims concerning the advantages of adopting a more complex sampling scheme are justified since this approach can serve to reduce the uncertainty in the interpretation of AMS results.

  18. What factors have influenced implementation of the Developmental Approaches in Science, Health and Technology program at two elementary schools on O'ahu, Hawai'i?

    NASA Astrophysics Data System (ADS)

    Carson, Lani L.

    This dissertation is a report of two hypothesis-generating qualitative case studies that investigated the factors that affected the successful school-wide implementation of the Developmental Approaches in Science, Health and Technology program, a spiraling, integrated, hands-on program for grades Kindergarten to 6 at two public elementary schools on the island of Oahu, in the state of Hawaii. Four key people were interviewed, 47 classrooms were observed three times each, and 41 of 48 teacher surveys were completed. An author-generated flow-of-influences conceptual framework based on other research findings about variables influencing the implementation of a curricular innovation delineates curricular, organizational, and external variables along with possible teacher-perceived outcomes. The results include 42 tables and 44 figures showing the many factors' positive and negative impacts on the schools' reform efforts. Eighteen hypotheses were generated. Well-planned implementations, strong administrative support and leadership, sustained follow-up support, and frequent collegial planning and sharing times seemed to have the greatest positive influences upon teacher confidence regarding program knowledge and sustained program use. More tenured teachers were using the program at levels equal to or greater than newer teachers until around twenty years of teaching experience, when there was a marked decline in program use.

    This report presents a summary of fieldwork conducted in Maunalua Bay, O'ahu, Hawaii to address coral-larval dispersal and recruitment from June through September, 2010. The objectives of this study were to understand the temporal and spatial variations in currents, waves, tides, temperature, and salinity in Maunalua Bay during the summer coral-spawning season of Montipora capitata. Short-term vessel surveys and satellite-tracked drifters were deployed to measure currents during the June 2010 spawning event and to supplement the longer-term measurements of currents and water-column properties by fixed, bottom-mounted instruments deployed in Maunalua Bay. These data show that currents at the surface and just below the surface where coral larvae are found are often oriented in opposite directions due primarily to tidal and trade-winds forcing as the primary mechanisms of circulation in the bay. These data extend our understanding of coral-larvae dispersal patterns due to tidal and wind-driven currents and may be applicable to larvae of other Hawaiian corals.

    Preliminary geological, geochemical, and geophysical field surveys have been conducted on Mokapu Peninsula on the island of Oahu in an effort to determine whether sufficient indications of geothermal potential exist within or adjacent to the peninsula to justify further, more detailed, exploratory efforts. An evaluation of existing geologic data as well as recently completed mapping on Mokapu indicate that the peninsula is located on the edge of or immediately adjacent to the inferred caldera of Koolau volcano. Geochemical surveys conducted within and around the Mokapu Peninsula included mercury and radon ground gas surveys as well as a limited evaluation of groundwater chemistry. Groundwater sampling on Mokapu Peninsula was severely restricted due to the absence of wells within the study area and thus water chemistry analyses were limited to the Nuupia fish ponds. Schlumberger resistivity soundings were completed in three locations on the peninsula: KVS1, in the northeast quadrant within the Ulupau crater, KVS2 in the northwest quadrant along the main jet runway, and KVS3 in the southeast along Mokapu Road. KVS1 encountered a relatively high resistivity to a depth of approximately 20 meters below sea level which was underlain by a basement resistivity of about 2 to 3 ohm meters. KVS2 and KVS3 detected similar resistivities of 2 to 3 ohm meters at much shallower depths (approximately equivalent to local sea level) below a thin, moderately resistive layer having an impedance ranging from 15 to 118 ohm meters.

    The Waialua basal-water body underlies an area of about 18 square miles on the north shore of the island of Oahu, Hawaii. The basal-water body is a body of fresh ground water that floats on saline ground water in a highly permeable and porous basaltic aquifer. Inflow to the basal-water body is from the deep infiltration of applied irrigation water and from leakage through a low permeability ground-water dam. Outflow from the basal-water body is from basal-water pumpage and leakage through low-permeability boundaries that separate the basal-water body from the ocean. The basal-water flux, computed as either the sum of the inflow terms or the sum of the outflow terms, is about the same value. The basal-water flux is 55 million gallons per day, (206,000 cubic meters per day), based on the sum of the outflow terms. The effective porosity was computed at 0.09 by a time-series analysis of the covariations in deep infiltration, pumpage, and basal-water head. The volume of basal water in storage is estimated to be 1.4 x 1011 gallons (5.4 x 108 cubic meters). Pumpage from the basal-water body can be increased. The most efficient development method is the skimming shaft. If shafts were used, an additional 15 million gallons per day could be pumped on a sustained basis.

    The study of fluvial bed sediments is essential for deciphering the impact of anthropogenic activities on water quality and drainage basin integrity. In this study, a systematic sampling design was employed to characterize the spatial variation of lead (Pb) concentrations in bed sediment of urban streams in the Palolo drainage basin, southeastern Oahu, Hawaii. Potentially bioavailable Pb was assessed with a dilute 0.5 N HCl extraction of the <63 μm grain-size fraction from the upper bed sediment layer of 169 samples from Palolo, Pukele, and Waiomao streams. Contamination of bed sediments was associated with the direct transport of legacy Pb from the leaded gasoline era to stream channels via a dense network of storm drains linked to road surfaces throughout the basin. The Palolo Stream had the highest median Pb concentration (134 mg/kg), and the greatest road and storm drain densities, the greatest population, and the most vehicle numbers. Lower median Pb concentrations were associated with the less impacted Pukele Stream (24 mg/kg), and Waiomao Stream (7 mg/kg). The median Pb enrichment ratio values followed the sequence of Palolo (68) > Pukele (19) > Waiomao (8). Comparisons to sediment quality guidelines and potential toxicity estimates using a logistic regression model (LRM) indicated a significant potential risk of Palolo Stream bed sediments to bottom-dwelling organisms.

    Survival of plagioclase in the residual melting column during melting can have a significant impact on the melting process beneath a mid-oceanic ridge [Asimow et al., Phil. Trans. R. Soc. London Ser. A 355 (1997) 255-281]. Here we investigate the origin of plagioclase that occurs in some rare mantle xenoliths from Oahu, Hawaii. The xenoliths are harzburgitic with less than 2 modal% clinopyroxene and are characterized by strong foliation and porphyroclastic texture. Olivine and orthopyroxene are common porphyroclasts; and only one xenolith (77PAII-9) contains a single large clinopyroxene porphyroclast with thick exsolved orthopyroxene lamellae. The strongly foliated groundmass shows well-developed triple-point junctions and is dominantly composed of olivine (ol 85-90 opx 7-14 cpx <1-2 plag 3-5 spinel trace). Spinel grains are small and dispersed through the groundmass and show extreme variation in Cr/Al ratio within individual thin sections, indicating that they are out of equilibrium with the other phases in these xenoliths. A highly anorthitic plagioclase (An 92-96) occurs only in the groundmass and its modal abundance (˜3-5%) is too high relative to the abundance of clinopyroxene (commonly <1%) for it to be a residual phase, implying that plagioclase may have an exotic origin. The porphyroclasts show strong compositional zoning near the rims and appear to be relict phases (as are all the spinel grains) that had once equilibrated with melts within the stability field of spinel peridotite (pressure ˜1-3 GPa). Clinopyroxene neoblasts and the single porphyroclast in PAII-9 are all characterized by lithosphere-like strongly depleted light rare earth element (chondrite-normalized) patterns. The clinopyroxene porphyroclast in PAII-9 is zoned in Al, Eu, Cr, and Na. The porphyroclastic ortho- and clinopyroxenes give a homogenized (host+exsolution) temperature of 1300°C, which is inferred to be the temperature at which the porphyroclast cores equilibrated with a MORB

    Lavas of the post-erosional, alkalic Honolulu Volcanics have significantly lower 87Sr 86Sr and higher 143Nd 144Nd than the older and underlying Koolau tholeiites which form the Koolau shield of eastern Oahu, Hawaii. Despite significant compositional variation within lavas forming the Honolulu Volcanics, these lavas are isotopically (Sr, Nd, Pb) very similar which contrasts with the isotopic heterogeneity of the Koolau tholeiites. Among Hawaiian tholeiitic suites, the Koolau lavas are geochemically distinct because of their lower iron contents and Sr and Nd isotopic ratios which range to bulk earth values. These geochemical data preclude simple models such as derivation of the Honolulu Volcanics and Koolau tholeiites from a common source by different degrees of melting or by mixing of two geochemically distinct sources. There may be no genetic relationship between the origin and evolution of these two lava suites; however, the trend shown by Koolau Range lavas of increasing 143Nd 144Nd and decreasing 87Sr 86Sr with decreasing eruption age and increasing alkalinity also occurs at Haleakala, East Molokai and Kauai volcanoes. A complex mixing model proposed for Haleakala lavas can account for the variations in Sr and Nd isotopic ratios and incompatible element abundances found in lavas from the Koolau Range. This model may reflect mixing and melting processes occurring during ascent of relatively enriched mantle through relatively depleted MORB-related lithosphere. Although two isotopically distinct components may be sufficient to explain Sr and Nd isotopic variations at individual Hawaiian volcanoes, more than two isotopically distinct materials are required to explain variations of Sr, Nd and Pb isotopic ratios in all Hawaiian lavas. ?? 1984.

    Total alkalinity (AT) is an important component of the marine inorganic carbon system that, together with one of the other measurable parameters (i.e., pH, dissolved inorganic carbon-CT , pCO2) allows us to calculate the entire CO2-carbonic acid system. By measuring AT continuously at several coastal locations on coral reefs of Oahu, we can calculate a current rate of change in surface water conditions with respect to biogeochemical processes as well as the globally important issue of ocean acidification (OA). Previous work by Drupp et al (2011, 2013) has shown that parameters of the CO2-carbonic acid system display seasonal fluctuations as well as respond to short term rainfall events. This work expands the period of study through July 2014. The three sampling locations are vastly different in geographic and geochemical conditions. Kaneohe Bay is a protected embayment, with large freshwater inputs and long water residence time compared to the nearshore exposed waters at Kilo Nalu and Ala Wai. Variation in coral reef environments affect AT, thus making it crucial to sample multiple environments over an extended period of time to reveal changes in biogeochemistry. A typical sample from Kaneohe Bay (CRIMP-2) can be expected to have a AT value between 2134 umol/kg and 2279 umol/kg, Kilo Nalu: between 2263 umol/kg and 2350 umol/kg, Ala Wai: between 2263 umol/kg and 2335 umol/kg. In general, total alkalinity values from CRIMP-2 are lower than at Kilo Nalu or Ala Wai due to differences in coral reef environments. Our long-term record allows us to compare the behavior of Hawaiian reef waters to those of other tropical marine ecosystems. Furthermore, monitoring of AT over extended multiple years and multiple locations is essential to develop the time-series data necessary for continued evaluation of the impact of OA on coral reefs of the Hawaiian Islands.

  7. Evolution of the lithosphere beneath Oahu, Hawaii: rare earth element abundances in mantle xenoliths

    Rare earth element contents of clinopyroxenes in Hawaiian mantle xenoliths from Oahu were determined with an ion microprobe. The analyzed xenoliths are from four vents of the alkali Honolulu Volcanics (HV). Three (Kaau, Pali and Kalihi—KPK) are located close to the caldera of the extinct Koolau shield volcano, and the fourth, Salt Lake Crater (SLC), is on the periphery of the shield volcano. Systematic differences exist in REE contents between clinopyroxenes of the KPK and SLC xenoliths: (1) KPK pyroxenes are typically zoned in REE contents whereas SLC pyroxenes are homogeneous, (2) the LREE-depleted (chondrite-normalized) patterns that characterize many of the KPK xenoliths are not found in SLC xenoliths, and (3) the convex-upward REE patterns that are characteristic of SLC xenoliths are not found in KPK xenoliths. Relative to abyssal peridotites, the LREE-depleted Hawaiian lherzolite pyroxenes (interpreted to be residual oceanic lithosphere) have higher contents of REE, Na 2O, TiO 2 and FeO, and more modal clinopyroxene. These LREE-depleted Hawaiian xenoliths represent deeper, less-depleted parts of the melting column, whereas the abyssal peridotites represent the uppermost, more strongly depleted part of the mantle. The spoon-shaped, LREE-enriched and convex-upward REE patterns in the xenoliths have resulted from metasomatic enrichment of the lithosphere caused by reaction with magmas that formed the Honolulu Volcanics. A model for the evolution of the oceanic lithosphere is presented in which fractures were the main mode of transport of the Honolulu Volcanics. Metasomatic enrichment resulted from interaction between percolating Honolulu Volcanics magmas and wallrock. The differences between SLC and KPK xenoliths are attributed to chromatographic fractionation effects: SLC xenoliths are postulated to have come from a greater depth where they equilibrated to a larger extent with the percolating magmas than the KPK rocks.

    The Koko fissure craters are aligned and nested basanitic tuff cones and rings at the SE corner of O'ahu, Hawai'i. There are no published studies of their stratigraphy, emplacement mechanisms or depositional paleoenvironments. This study focuses on a tuff cone complex (Koko Crater) and a younger adjacent nested tuff ring (Hanauma Bay). A detailed stratigraphy with logged sections for both Koko Crater and the Hanauma Bay craters are presented and discussed. Koko Crater is dominated by wet fallout deposits on steep proximal slopes, commonly resedimented by hot (vesiculated) and cold (unvesiculated) debris flows, slumps and slides, but with an increasing percentage of wet (low temperature) low concentration PDC deposits preserved in the shallowly-dipping flanking apron deposits, and in the uppermost proximal deposits. At least two earlier cone or ring rims are preserved along its southern margin. The deposits of Hanauma Bay overlie the Koko deposits and are dominated by a mix of wet low concentration PDC, wet fallout and synchronous PDC, and fallout deposits in proximal settings, and by low concentration, probably drier, PDC deposits in more distal settings. The Hanauma Bay rings were emplaced before the Koko Crater tephra was consolidated, as steep-sided rills incised into Koko tephra are locally filled with tephra of mixed Koko and Hanauma sources. The onset of Hanauma Bay eruptions is marked by a horizon that is very rich in rounded coral sand clasts. Discontinuous horizons and lenses of coral block fallout are also very common in the Hanauma tephra. Coral sand is absent and coral blocks are much rarer in the Koko tephra. These observations, and probably also the dominance of wet fallout at Koko, imply that Koko was erupted in deeper water than the nearshore coral beach environment of the Hanauma rings. A faster rate of water recharge into the conduit in deeper open water is probably the most important factor in the generation of a cone rather than a ring at this

    The deterministic Stability INdex MAPping (SINMAP) model, which integrates a mechanistic infinite-slope stability model and a hydrological model, was applied to assess susceptibility of slopes in 32 shallow-landslide-prone watersheds of the eastern to southern areas of Oahu, Hawaii, USA. Input to the model includes a 10-m Digital Elevation Model (DEM), an inventory of storm-induced landslides that occurred from 1949 to 2006, and listings of soil-strength and hydrological parameters including transmissivity and steady-state recharge. The study area of ca. 384 km 2 was divided into four calibration regions with different geotechnical and hydrological characteristics. All parameter values were separately calibrated using observed landslides as references. The study used a quasi-dynamic scenario of soil wetness resulting from extreme daily rainfall events with a return period of 50 years. The return period was based on almost-90-year-long (1919-2007) daily rainfall records from 26 raingauge stations in the study area. Output of the SINMAP model includes slope-stability-index-distribution maps, slope-versus-specific-catchment-area charts, and statistical summaries for each region. The SINMAP model assessed susceptibility at the locations of all 226 observed shallow landslides and classified these susceptible areas as unstable. About 55% of the study area was predicted as highly unstable, highlighting a critical island problem. The SINMAP predictions were compared to an existing debris-flow-hazard map. Areas classified as unstable in the current study were classified as low-to-moderate and moderate-to-high debris-flow hazard risks by the prior mapping. The slope-stability maps provided by this study will aid in explaining the causes of known landslides, making emergency decisions, and, ultimately mitigating future landslide risks. The maps may be further improved by incorporating heterogeneous and anisotropic soil properties and spatial and temporal variation of

    Ease of access, size, and basalt as the dominant bedrock make Oahu an ideal locality for investigating chemical weathering-driven denudation rates as a function of climate (rainfall varies by an order of magnitude), water-rock contact time, and soil thickness. New and compiled surface and groundwater solute data permit calculation of mass balances for solute fluxes from Oahu, revealing that groundwater dominates surface water solute fluxes by a factor of 3-12. Weathering reactions were written consistent with the mineralogy of Oahu soils, permitting denudation rates to be partitioned between dissolved and suspended loads. Total denudation rates, indexed to the leaching of SiO2, vary from 0.016 to 0.063 m/ka, with about 70% of Si transport due to dissolved loads. Drier regions of Oahu have distinctly lower denudation rates, and areas with thick weathering profiles have suppressed surface-water solute loads. Indexing denudation in basaltic terranes to dissolved SiO2 rather than other solutes leads to improved estimates of weathering rates. Other approaches require correction for the atmospheric depositions of sea salts based on Cl- abundances in waters that are assumed to derive solely from the ocean via atmospheric deposition. Recent work indicates that Oahu is tectonically emerging at 0.060 m/ka. As long as this uplift continues, the net size of the island will slowly increase and the Koolau Range should persist as an orographic trap to precipitation, maintaining relative aridity in the Waianae Range. Comparing emergence and denudation rates suggests that growth of the island will be non-uniform, with arid regions experiencing the greatest emergence with wet regions in balance with denudation. More importantly, however, this work offers an increased appreciation of the controls on the rates and mechanisms of denudation in basaltic and intermediate composition terranes in the tropics.

  11. Geohydrology of the Central Oahu, Hawaii, Ground-Water Flow System and Numerical Simulation of the Effects of Additional Pumping

    1998-01-01

    A two-dimensional, finite-difference, ground-water flow model was developed for the central Oahu flow system, which is the largest and most productive ground-water flow system on the island. The model is based on the computer code SHARP which simulates both freshwater and saltwater flow. The ground-water model was developed using average pumping and recharge conditions during the 1950's, which was considered to be a steady-state period. For 1950's conditions, model results indicate that 62 percent (90.1 million gallons per day) of the discharge from the Schofield ground-water area flows southward and the remaining 38 percent (55.2 million gallons per day) of the discharge from Schofield flows northward. Although the contribution of recharge from infiltration of rainfall and irrigation water directly on top of the southern and northern Schofield ground-water dams was included in the model, the distribution of natural discharge from the Schofield ground-water area was estimated exclusive of the recharge on top of the dams. The model was used to investigate the long-term effects of pumping under future land-use conditions. Future recharge was conservatively estimated by assuming no recharge associated with agricultural activities. Future pumpage used in the model was based on the 1995-allocated rates. Model results indicate that the long-term effect of pumping at the 1995-allocated rates will be a reduction of water levels from present (1995) conditions in all ground-water areas of the central Oahu flow system. In the Schofield ground-water area, model results indicate that water levels could decline about 30 feet from the 1995 water-level altitude of about 275 feet. In the remaining ground-water areas of the central Oahu flow system, water levels may decline from less than 1 foot to as much as 12 feet relative to 1995 water levels. Model results indicate that the bottoms of several existing deep wells in northern and southern Oahu extend below the model

    2011-12-01

    Access, size, basalt as the dominant bedrock, and climate variation (rainfall varies by 10x) make Oahu, Hawaii, USA an ideal locality for investigating chemical weathering driven denudation rates. New and compiled surface and groundwater solute data permit calculation of mass balances for solutes from Oahu, revealing that groundwater solute fluxes dominate surface water by a factor of 3 to 12, neglecting if biogenic silica removal by streams. Weathering reactions consistent with the observed mineralogy of Oahu soils and the calculated mineralogy of shield-forming tholeiitic basalts permit denudation rates to be partitioned between dissolved and suspended loads where long term erosion via streams and soil formation rates are assumed to be in a steady state. Aerially averaged denudation rates, indexed to the leaching of SiO2, vary from 0.016 to 0.063 m/ka, with about 70% of denudation due to dissolved fluxes. Thus, groundwater appears to be the single most important source of mass flux to the ocean from ocean islands. Dry regions of Oahu have distinctly lower denudation rates, and areas with thick soil profiles have suppressed solute loads in streams because laterites and subjacent saprolites have already been largely depleted in mobile elements. However, systematic differences also exist due to different contact times between groundwater and aquifer materials. The short, shallow circulation of stream base flows permits less extensive reaction with basalt resulting in lower solute loads even in areas where thick soils are largely absent. In addition to larger total water fluxes, deep groundwaters exhibit elevated solute loads across Oahu. Indexing denudation in basaltic terranes to dissolved SiO2, a minor component in seawater, rather than other solutes leads to improved estimates of weathering rates in ocean islands. Other approaches require correction for the atmospheric depositions of sea salts based on Cl- abundances in waters that are assumed to derive solely

    Field tests indicate that an abandoned well (No. 2401-01) near the confluence of Waikele and Kipapa Streams, Oahu, Hawaii, can be reactivated to produce potable water at a rate of 400-500 gallons per minute. Previous tests in 1946 and 1954 indicated that the well tapped the brackish transition zone which inderlies the Ghyben-Herzberg lens of the Pearl Harbor aquifer. Results of this study, based on geologic and geophysical logs of the wall, as well as on pumping test and water-quality data, indicate that the slightly brackish water produced by the well results from brackish irrigation return water. It does not appear that pumping from this well will cause seawater upconing or intrusion. (USGS)

    This study examines the effect of sewage discharge on benthic polychaete assemblages in the context of their functional trophic categories. We present data spanning 20 years of monitoring benthic invertebrate assemblages and sediment properties at all 4 primary- and secondary-treatment wastewater outfalls servicing Honolulu and the island of Oahu, Hawaii, USA. Samples collected within mandated zones of initial dilution (ZIDs) near outfall discharge sites were compared to samples collected at reference stations at varying distances away. Our findings indicate that sediment properties were not affected by the outfall discharge rate or distance from each ZID. The number of polychaete species in 4 functional trophic categories (carnivore, detritivore, omnivore, and suspension feeder) did not change with the outfall solid loading rate or with distance from each ZID, thus suggesting relatively little organic enrichment. We find no evidence of heavy organic enrichment beyond the designated ZIDs at these 4 wastewater outfalls. PMID:24735911

    Izuka, Scot K.; Hill, Barry R.; Shade, Patricia J.; Tribble, Gordon W.

    1993-01-01

    A combination of geologic mapping, seepage runs, water-budget computation, analysis of stream-gaging records, study of stream sediment, and measurement of polychlorinated biphenyls (PCBs) was used to investigate the geohydrology and possible routes of PCB transport from areas of possible contamination in the U.S. Coast Guard's Omega Station in Haiku Valley, Oahu, Hawaii. The PCBs were a contaminant in fuel that was sprayed on vegetation and ignited during defoliation efforts at the Omega Station. Haiku Valley is a stream valley eroded into a thick section of dike-intruded, highly permeable lava flows. The valley is partly filled with alluvium, pyroclastics and massive lava flows. A shallow aquifer system is formed by a permeable unit of pyroclastics which is bounded below by less permeable alluvium, massive lava flows, and weathered basalt. A deeper aquifer system is present in the dike-intruded lava flows. Much of the area of suspected PCB-contaminated fuel application in Haiku Valley is situated on the geologic unit that forms the shallow aquifer. A water budget calculated for the drainage area of a stream-gaging station (16275000) at the downgradient boundary of the Omega Station indicates that the shallow and deep aquifers receive recharge of 5.1 cubic feet per second from the 0.98 square-mile drainage area; approximately 10 percent of the drainage area is suspected to have been contaminated by PCBs. Approximately 4 cubic feet per second of water is withdrawn from the aquifers by a well and a water tunnel in the valley, but the geology of the area indicates that some of the water withdrawn by the tunnel also comes from recharge beyond the surface-water divides of Haiku Valley. Base flow to the stream is about 1.2 cubic feet per second. A water-balance calculation between recharge, well and tunnel withdrawals, and stream base flow, indicates that 1.0 cubic feet per second or more of the water recharging the drainage area may travel through the subsurface and

  18. Evaluation of Major Dike-Impounded Ground-Water Reservoirs, Island of Oahu

    1985-01-01

    Ground-water reservoirs impounded by volcanic dikes receive a substantial part of the total recharge to ground water on the island of Oahu because they generally underlie the rainiest areas. These reservoirs accumulate the infiltration from rainfall, store it temporarily, and steadily leak it to abutting basal reservoirs or to streams cutting into them. The dike reservoirs have high hydraulic heads and are mostly isolated from saline water. The most important and productive of the dike-impounded reservoirs are in an area of about 135 square miles in the main fissure zone of the Koolau volcano where the top of the dike-impounded water reaches an altitude of at least 1,000 feet. Water is impounded and stored both above and below sea level. The water stored above sea level in the 135 square mile area has been roughly estimated at 560 billion gallons. In comparison, the water stored above sea level in reservoirs underlying a dike-intruded area of about 53 square miles in the Waianae Range has been roughly estimated at 100 billion gallons. Storage below sea level is indeterminable, owing to uncertainties about the ability of the rock to store water as dike density increases and porosity decreases. Tunnels, by breaching dike controls, have reduced the water stored above sea level by at least 50 billion gallons in the Koolau Range and by 5 1/2 billion gallons in the Waianae Range, only a small part of the total water stored. Total leakage from storage in the Koolau Range has been estimated at about 280 Mgal/d (million gallons per day). This estimated leakage from the dike-impounded reservoirs makes up a significant part of the ground-water yield of the Koolau Range, which has been estimated to range from 450 to 580 Mgal/d. The largest unused surface leakage is in the Kaneohe, Kahana, and Punaluu areas, and the largest unused underflow occurs in the Waialee, Hauula-Laie, Punaluu, and Kahana areas. The unused underflow leakage is small in areas near and east of Waialae, but

  1. Tsunami deposits at MIS Stages 5e and 9 on Oahu, Hawaii: implications for sea level at interglacial stages

    Sandy, basalt-coral conglomerates associated with both beachrock and coral reefs are found at high elevations on Oahu, Hawaii. They have been attributed to either brief, sea level high-stands or storms. The Kahe Point conglomerates are at 12.5 m elevation, whereas the main stage MIS-5e reef at this location has a maximum elevation of 8.2 m. They are loosely consolidated and poorly cemented, graded, poorly sorted, and with varying amounts of basalt and coral clasts ranging from cobble to boulder size. Coral in these deposits has been U-series dated by us at between 120-125 ka (n=5). Four distinct beds, with a gently seaward tilt, are recognized in a road cut section, with each bed composed of a few cm-thick topset bed of fine-grained, shelly, calcareous sand to silt. Similar high elevation conglomerates and 5e reefs are also described at Mokapu and Kaena Points on Oahu, indicating an island-wide deposit. Older coral clasts, dated at 130 to 142 ka (n=6; oldest by alpha spectrometry) found in association with the stage 5e corals suggest reworking and incorporation of older low-stand reef material. The coarse grain size of the conglomerates indicates deposition from a high-energy event; thus a high-stand source is ruled out. We also consider that the overall lithology and up to 0.5 m bed thickness not to be the result of storms; a series of high frequency storm events is considered unlikely. The weight of the evidence in our opinion clearly indicates deposition by a series of tsunami waves. If correct, this has implications for “probabilistic” models of sea level peaks at least 6.6 m higher than present at stage 5e that use such data in their models (e. g., Kopp et al., 2009), at least for Oahu. Within about 2 km of the Kahe deposit, in a road cut at Ko Olina, there is another markedly similar high-energy, sandy basalt-bearing coral conglomerate sequence at 21 to 25 m elevation. There are at least two distinct beds about one meter in thickness, both gently seaward

  2. Evaluation and Optimization of CMIP5 Data using an Artificial Neural Network for Dynamical Downscaling of rainfall on Oahu, Hawaii

    Understanding long-term changes of rainfall is important for water resources planning and development. General Circulation Models (GCMs) such as those used in CMIP5 have undergone significant improvements since the early development of Numerical Weather Prediction. CMIP5's RCP8.5 experiment was comprised of over 20 different GCM configurations using various parameterization schemes and initial conditions to project the future climate in response to anthropogenic warming. However due to coarse spatial resolution and simple parameterization schemes of GCMs, current rainfall estimates and future rainfall projections are often unrealistic, especially for small islands with complex terrains such as the Hawaiian Islands. Recent advancements in mesoscale meteorology have helped develop limited area Regional Climate Models (RCMs) such as WRF-ARW that have the ability to estimate and project high-resolution rainfall at smaller scales, in our case down to 1.1km. RCMs often use GCM output for their initial lateral boundary conditions and prescribed land surface conditions. In the original WRF system, there is a land surface model but small Hawaiian Islands such as Oahu is not well represented in the land surface datasets of the official WRF model release. Therefore, we made effort to improve land surface characteristics (e.g., albedo, green vegetation fraction) suitable for 1.1 km domain over Oahu. Since high-resolution RCM output is forced by the lateral boundary conditions, we see significant variations in estimated and future projected rainfall depending on which GCM was chosen to force the RCM. To combat this issue we implement an Artificial Neural Network using a simple Sequential Learning Algorithm (SLA) to evaluate the GCM's ability to simulate the current climate, allowing us to choose the optimum lateral boundary conditions that drive the RCM. In our study we use CMIP5's monthly means output from several different models that included both the Historical and RCP8

    It is imperative that coastal erosion studies produce valid erosion rates and erosion hazard predictions to aid in the development of public policy and protect coastal resources. Currently, the Single-Transect method is the most common shoreline change model, which calculates a rate at each shore-normal transect without regard to influences of data from adjacent transects along a beach. Improving on Single-Transect, the University of Hawaii Coastal Geology Group has developed the PX (Polynomial in distance X) and PXT (Polynomial in distance X and Time) shoreline change rate calculation methods, which model all the shoreline positions within a beach simultaneously using polynomial techniques. PX is a special case of PXT that models shoreline change rates spatially along a beach. PXT not only models the shoreline change spatially, but it lets the rate change with time (acceleration). This is an important advance, as beaches may not erode or accrete at a constant (linear) rate. A linear sum of basis functions characterizes the shoreline change rate for both PX and PXT. These methods are an improvement on previous methods as they produce more meaningful, i.e., statistically significant rates and erosion hazard predictions. We use an information criterion (gMDL) to (1) identify the number of coefficients of the basis functions that are needed to describe shoreline change in PX and PXT, and (2) compare different methods to determine which method best describes shoreline change. The southeast coastline of Oahu, Hawaii, features a range of beach morphologies and littoral dynamics well suited for further testing of the PX and PXT shoreline change rate calculation methods. The PX and PXT methods find significant rates for 70% of the study area versus 28% significant rates with the Single-Transect method. In companion with the work presented by Ayesha Genz on the PX and PXT rate methods, we present results from the Southeast Oahu Shoreline Study as a demonstration of the

    Organochlorine pesticides were heavily used from the mid-1940s to the mid-1980s. The persistence of organochlorine pesticides, their tendency to accumulate in soil, sediment, and biota, and their harmful effects on wildlife brought this class of compounds into disfavor and eventually resulted in restriction or cancellation of most of them in the United States (Nowell and others, 1999). Despite use restrictions, these compounds continue to be detected in sediment and fish tissue samples. This study was undertaken as part of the National Water-Quality Assessment (NAWQA) program of the U.S. Geological Survey (USGS). The NAWQA program assesses watersheds as integrated systems, focusing on chemical concentrations, physical conditions, and biological status in streams. One component of NAWQA is an occurrence survey of organic contaminants and trace elements in stream bed sediment and fish tissue. The goal of the Oahu stream bed sediment and fish tissue occurrence survey was to determine which organochlorine contaminants are present in streams around the island, and with which land uses they are associated. An understanding of relations between land use and organochlorine compounds will allow land management practices to be designed to reduce the loading of contaminants to streams and nearshore waters.

  7. Structure, stratigraphy, and eruption dynamics of a young tuff ring: Hanauma Bay, O'ahu, Hawai'i

    The Hanauma Bay-Koko Head complex is one of several young volcanic landforms along the Koko fissure, in southeastern O'ahu. The Hanauma Bay region of the complex comprises two nested tuff rings, inner and outer Hanauma Bay, and multiple smaller vents. The internal structure of the inner tuff ring, well exposed due to subsequent breaching by the ocean and wave erosion, indicates that it formed during a minimum of five distinct phases of deposition that produced five mappable units. Significant inward collapses generated major unconformities that separate the units exposed in the inner wall. The planes of failure are cut by narrow steep-walled, locally overhung channels and gullies, suggesting that the collapse events were each followed by short time breaks during which the deposits were eroded by rainfall runoff. Within each pyroclastic unit, there are many local slump scars and unconformities, suggesting that minor instability of the inner wall was a near-constant feature. From bedding sags and surge bed forms, it is apparent that the vent shifted at least twice during tuff ring growth. Ballistic blocks in the youngest unit indicate that the eruption overlapped in time with a separate eruption to the north, most likely to be that of the Kahauloa tuff ring 880 m away.

    In the second half of the 19th century, Jean-Martin Charcot (1825-1893) became famous for the quality of his teaching and his innovative neurological discoveries, bringing many French and foreign students to Paris. A hunger for recognition, together with progressive and anticlerical ideals, led Charcot to invite writers, journalists, and politicians to his lessons, during which he presented the results of his work on hysteria. These events became public performances, for which physicians and patients were transformed into actors. Major newspapers ran accounts of these consultations, more like theatrical shows in some respects. The resultant enthusiasm prompted other physicians in Paris and throughout France to try and imitate them. We will compare the form and substance of Charcot's lessons with those given by Jules-Bernard Luys (1828-1897), Victor Dumontpallier (1826-1899), Ambroise-Auguste Liébault (1823-1904), Hippolyte Bernheim (1840-1919), Joseph Grasset (1849-1918), and Albert Pitres (1848-1928). We will also note their impact on contemporary cinema and theatre. PMID:25273491

    its high spatial and spectral resolution, it was possible to zoom into the very heart of this very massive star. In this innermost region, the observations are dominated by the extremely dense stellar wind that totally obscures the underlying central star. The AMBER observations show that this dense stellar wind is not spherically symmetric, but exhibits a clearly elongated structure. Overall, the AMBER observations confirm that the extremely high mass loss of Eta Carinae's massive central star is non-spherical and much stronger along the poles than in the equatorial plane. This is in agreement with theoretical models that predict such an enhanced polar mass-loss in the case of rapidly rotating stars. ESO PR Photo 06c/07 ESO PR Photo 06c/07 RS Ophiuchi in Outburst Several papers from this special feature focus on the later stages in a star's life. One looks at the binary system Gamma 2 Velorum, which contains the closest example of a star known as a Wolf-Rayet. A single AMBER observation allowed the astronomers to separate the spectra of the two components, offering new insights in the modeling of Wolf-Rayet stars, but made it also possible to measure the separation between the two stars. This led to a new determination of the distance of the system, showing that previous estimates were incorrect. The observations also revealed information on the region where the winds from the two stars collide. The famous binary system RS Ophiuchi, an example of a recurrent nova, was observed just 5 days after it was discovered to be in outburst on 12 February 2006, an event that has been expected for 21 years. AMBER was able to detect the extension of the expanding nova emission. These observations show a complex geometry and kinematics, far from the simple interpretation of a spherical fireball in extension. AMBER has detected a high velocity jet probably perpendicular to the orbital plane of the binary system, and allowed a precise and careful study of the wind and the shockwave

  7. Using sediment 'fingerprints' to assess sediment-budget errors, north Halawa Valley, Oahu, Hawaii, 1991-92

    Reliable estimates of sediment-budget errors are important for interpreting sediment-budget results. Sediment-budget errors are commonly considered equal to sediment-budget imbalances, which may underestimate actual sediment-budget errors if they include compensating positive and negative errors. We modified the sediment 'fingerprinting' approach to qualitatively evaluate compensating errors in an annual (1991) fine (<63 ??m) sediment budget for the North Halawa Valley, a mountainous, forested drainage basin on the island of Oahu, Hawaii, during construction of a major highway. We measured concentrations of aeolian quartz and 137Cs in sediment sources and fluvial sediments, and combined concentrations of these aerosols with the sediment budget to construct aerosol budgets. Aerosol concentrations were independent of the sediment budget, hence aerosol budgets were less likely than sediment budgets to include compensating errors. Differences between sediment-budget and aerosol-budget imbalances therefore provide a measure of compensating errors in the sediment budget. The sediment-budget imbalance equalled 25% of the fluvial fine-sediment load. Aerosol-budget imbalances were equal to 19% of the fluvial 137Cs load and 34% of the fluval quartz load. The reasonably close agreement between sediment- and aerosol-budget imbalances indicates that compensating errors in the sediment budget were not large and that the sediment-budget imbalance as a reliable measure of sediment-budget error. We attribute at least one-third of the 1991 fluvial fine-sediment load to highway construction. Continued monitoring indicated that highway construction produced 90% of the fluvial fine-sediment load during 1992. Erosion of channel margins and attrition of coarse particles provided most of the fine sediment produced by natural processes. Hillslope processes contributed relatively minor amounts of sediment.

  8. Relatively Recent Volcanism on Oahu, Hawaii: New U-series and Paleomagnetic Age Constraints on the Hanauma Bay Eruption

    The Koko Rift Zone (KRZ), eastern Oahu, is generally regarded as among the youngest volcanic features on the island. Previous workers have suggested that the 9 or 10 vents of this rift erupted near-simultaneously. However, K-Ar data in the literature (32-39 ka vs 320 ka) provide only general guidance on the youthfulness of these eruptions. We present new age constraints on KRZ volcanism using deposits of the phreatomagmatic eruption that produced Hanauma Bay (a popular snorkeling spot) and spatially associated lava flows. Numerous continuous basaltic ash units within the walls of Hanauma crater contain lithic fragments of well-preserved coral reef, beach rock, and marine mollusks, indicating that the eruption occurred in a near shore environment. 238U-234U-230Th dating of coral clasts in the deposit demonstrates that the eruption breached reef of MIS stage 7 age (200 +/- 30 ka), thereby ruling out the K-Ar age of 320 ka. U-series nuclides in "normal" MIS 7 coral lithics are indistinguishable from those in the island encircling Waianae Reef of the same age. However, U-series components in some originally aragonitic coral clasts were offset during the eruption when the rims recrystallized to calcite. 87Sr/86Sr, 234U/238U and Sr and U concentration indicate chemical mixing with host basaltic ash during this event, from which potential ages of the eruption can be constructed using isochron methods. More modeling of the data remains to be done but our preliminary estimate places the eruption at less than 100 ka. This result is consistent with new data on paleointensity and paleomagnetic secular variation within the lava flows exposed in or around the crater. This U-series dating approach should prove useful for eruptions in other locales where carbonate bioclast lithics are present in the deposits.

    Sandy ocean beaches are a popular recreational destination, and often are surrounded by communities that consist of valuable real estate. Development is increasing despite the fact that coastal infrastructure may be repeatedly subjected to flooding and erosion. As a result, the demand for accurate information regarding past and present shoreline changes is increasing. Working with researchers from the University of Hawaii, investigators with the U.S. Geological Survey's National Assessment of Shoreline Change Project have compiled a comprehensive database of digital vector shorelines and shoreline-change rates for the islands of Kauai, Oahu, and Maui, Hawaii. No widely accepted standard for analyzing shoreline change currently exists. Current measurement and rate-calculation methods vary from study to study, precluding the combination of study results into statewide or regional assessments. The impetus behind the National Assessment was to develop a standardized method for measuring changes in shoreline position that is consistent from coast to coast. The goal was to facilitate the process of periodically and systematically updating the measurements in an internally consistent manner. A detailed report on shoreline change for Kauai, Maui, and Oahu that contains a discussion of the data presented here is available and cited in the Geospatial Data section of this report.

    Absolute Paleointensity determinations coupled with directional analyses and precise 40Ar/39Ar radioisotopic dating, have rendered a record of an excursion of the geomagnetic field providing an insight of the rapid variation of the short-term behavior of the paleomagnetic field. We have sampled a long volcanic section located on the buttressed flank of the Koolau volcano within the Halawa Valley, Oahu, Hawaii and studied 120 m thick sequence of flows providing an excellent candidate for detailed paleomagnetic analysis. At least eight samples collected from each of 28 successive flow-sites were stepwise demagnetized by both alternating field (5mT to 100mT) and thermal (from 28° C to 575-650°C) methods, and the mean directions obtained by principal component analysis. All samples yielded a strong and stable ChRM trending towards the origin based on no less than seven to nine steps, with thermal and AF results agreeing to a very high degree. Low field susceptibility versus temperature (k-T) analyses were conducted for individual lava flows, and the majority of them show reversible curves. Curie point determinations revealed a temperature close to or equal to 580°C, indicative of almost pure magnetite for most of the flows. Magnetic grain sizes analysis indicated SD-PSD sizes. The mean directions of magnetization of the entire section sampled indicate that about 10 m of the section are characterized by excursional directions (5 lava flows). In addition to the directional analyses we performed absolute paleointensity determinations on the 28 lavas sampled. We used the modified Thellier- Coe double heating method to determine paleointensities. pTRM checks were performed systematically one temperature step down the last pTRM acquisition in order to document magnetomineralogical changes during heating. The temperature was incremented by steps of 50° C between room temperature and 500°C and every 25-30° C. The paleointensity determinations were obtained from the slope

    New paleomagnetic measurements (directions and paleointensity determinations), coupled with precise 40Ar/39Ar radioisotopic dating, are revolutionizing our understanding of the geodynamo by providing detailed terrestrial lava records of the short-term behavior of the paleomagnetic field. As part of an investigation of the evolution of Koolau Volcano (one of the volcanoes comprising Oahu Island) and the short-term behavior of the geomagnetic field, we have sampled a long volcanic section located on the buttressed flank of the volcano within Halawa Valley. Prior paleomagnetic and K-Ar investigations of the Koolau (Volcano) Series revealed excursional directions (Site F of Doell and Dalrymple, 1973). The alkaline composition of lava flows, easy access, and close geographical proximity to K-Ar dated lava flows made this newly studied 120 m thick sequence of flows in Halawa valley an excellent candidate for detailed paleomagnetic analysis. At least eight samples collected from each of 28 successive flow-sites were stepwise demagnetized by both alternating field (5mT to 100mT) and thermal (from 28° C to 575-650°C) methods, and the mean directions obtained by principal component analysis.

  17. Isotope and trace element characteristics of Waianae Volcano, Oahu, Hawaii: evidence for crustal melting in Hawaiian volcanoes

    NASA Astrophysics Data System (ADS)

    Well-exposed sections within the 3-4 Ma Waianae Volcano of Oahu, Hawaii, encompass much of the Hawaiian volcano "life" cycle, ranging from early or main shield stage (Lualualei) through late shield (Kamaileunu) to postshield (Palehua and Kolekole) stage. New data on 25 samples indicate a relatively restricted range in Sr, Nd and Pb isotopic ratios. 87Sr/86Sr ranges from 0.70352 to 0.70379, \\UpsilonNd from +4.5 to +6.7 and 206Pb/204Pb 17.793 to 18.295. The largest range within the sample suite occurs in the shield stage lavas (Lualualei and Kamaileunu), suggesting less time for homogenization of magma in a magma chamber(s) during this period. The late shield stage contains silicic lavas and dikes (basaltic icelandites, icelandites and rhyodacites). In 206Pb/204Pb versus 207Pb/204Pb or ^{208}Pb/204Pb diagrams, most shield and postshield lavas fall on a single array, which may be a binary (or pseudo-binary) mixing array. However, data for the silicic lavas lie well off the array at low 206Pb/204Pb (~17.8). Incompatible-element patterns for these samples are distinct in having peaks at Pb. Greater scatter in Sr-Pb and Nd-Pb isotope diagrams compared to Pb-Pb isotope diagrams suggests that the variations in Sr-Pb and Nd-Pb isotope diagrams are related to fractionation of Sr, Nd and Pb by different degrees of melting of different components. Geochemical modeling of the isotopic and trace element data suggests that the silicic lavas (which are petrographically, chemically and mineralogically calc-alkalic) likely represent hydrous melts of amphibolite in the lower Hawaiian crust. We propose that the occurrence of these lavas in the late shield stage results from deep crustal melting as a consequence of compression and crustal thickening after the accumulation and alteration of a thick pile of lavas earlier in the shield stage. The Koolau Volcano's late shield (Makapuu stage) exhibits similar Pb isotope ratios, perhaps indicating that the "exotic" Koolau component might

    Molten magnesium oxidizes rapidly when exposed to air causing melt loss and handling difficulties. The use of certain additive gases such as SF6, SO2, and CO2 to form a protective MgO layer over a magnesium melt has been proposed. The oxidation behavior of molten magnesium in air containing various concentrations of SF6 was investigated. Measurements of the kinetics of the oxide layer growth at various SF6 concentrations in air and temperatures were made. Experiments were performed using a thermogravimetric analysis unit in the temperature range of 943 K to 1043 K (670 °C to 770 °C). Results showed that a thin, coherent, and protective MgF2 layer was formed under SF6/Air mixtures, with a thickness ranging from 300 nm to 3 μm depending on SF6 concentration, temperature, and exposure time. Rate parameters were calculated and a model for the process was developed. The morphology and composition of the surface films were studied using scanning electron microscope and energy-dispersive spectroscope.

    Dr Marjorie Clifton describes the classification of gaseous and nongaseous constituents of air pollution and then outlines the methods of measuring these. The National Survey embraced 150 towns of all sizes throughout England and Wales and provided data on smoke and sulphur dioxide in relation to climate, topography, industrialization, population density, fuel utilization and urban development. Dr W C Turner discusses the relationship between air pollution and mortality from respiratory conditions, and particularly the incidence of chronic bronchitis. He postulates a theory that such respiratory conditions arise as an allergy to the spores of certain moulds, spore formation being encouraged by the air humidity in Greatv Britain and overcrowded and damp living conditions. He describes the results of a twenty-week study undertaken in 1962-3, showing associations between respiratory disease and levels of air pollution. Dr Stuart Carne undertook a survey in general practice to plot the patterns of respiratory illness in London during the winter of 1962-3. There were two peaks of respiratory illnesses coinciding with the fog at the beginning of December and the freeze-up from the end of December until the beginning of March. PMID:14178955

  6. The Role of Dissolved Loads Partitioned Between Surface and Ground Waters in the Chemical Weathering Rates of Tropical Islands Under Varied Climates: A Preliminary Assessment from Oahu, Hawaii, USA

    NASA Astrophysics Data System (ADS)

    2009-12-01

    The island of Oahu, Hawaii, USA is an ideal natural laboratory for understanding the role of climate, surface waters, and ground waters in the erosion and ultimate disappearance of ocean islands. This island is in a post-constructional phase, is composed entirely (or nearly so) of a single rock type (tholeiitic basalt), and rainfall totals vary by about an order of magnitude. On portions of the windward Koolau Range, rain exceeds 7 m annually, whereas portions of the southern island receive less than 0.8 m per year. There is considerable variability in the geochemical facies and total dissolve solid (TDS) content of surface and groundwaters, even among samples from similar climatic settings. Most waters tend to be of the Na-Mg-Cl type. However, ground waters tend to have higher TDS loads than surface waters, indicative of longer contact times with rock. 3H contents of wells average 0.6 TU, streams 1.2 TU, and rain 1.7 TU. Thus, the mean residence of groundwater may be on the order of 15-20 yr. Portions of Oahu such as the north central agricultural region have extremely well-developed soils, and TDS contents are very low on average (<70 mg/L) and similar to rainwater. Ground waters exhibit elevated solute loads, but when corrected for solutes in precipitation, only 50 to 60 additional mg/L have been acquired through water-rock interaction. By contrast, windward Oahu is dominated by the steep slopes of the Koolau Range where thick soils cannot accumulate, and relatively fresh rock is continuously exposed to weathering. When corrected for the contribution of rain, windward ground waters average >600 mg/L derived from water-rock interaction. Oahu has been subdivided into 5 major hydrographic regions and existing water budgets for Oahu can be coupled with mean solute loads for ground and surface water to estimate denudation rates via dissolved loads. Weathering products removed by surface waters are not considered here. Windward and south central Oahu are eroding at

  8. Hydrology and Water and Sediment Quality at James Campbell National Wildlife Refuge near Kahuku, Island of Oahu, Hawaii

    USGS Publications Warehouse

    Hunt, Charles D., Jr.; De Carlo, Eric H.

    2000-01-01

    The James Campbell National Wildlife Refuge occupies two lowland marsh and pond complexes on the northern coastal plain of Oahu: the mostly natural ponds and wetlands of the Punamano Unit and the constructed ponds of the Kii Unit. The U.S. Fish and Wildlife Service manages the Refuge primarily to protect and enhance habitat for four endangered species of Hawaiian waterbirds. Kii Unit is fed by artesian wells and rainfall, whereas Punamano Unit is fed naturally by rainfall, runoff, and ground-water seepage. Streams drain from the uplands into lowland ditches that pass through Kii Unit on their way to the ocean. A high-capacity pump transfers water from the inner ditch terminus at Kii to the ocean outlet channel. Stormwaters also exit the inner ditch system over flood-relief swales near the outlet pump and through a culvert with a one-way valve. A hydrologic investigation was done from November 1996 through February 1998 to identify and quantify principal inflows and outflows of water to and from the Refuge, identify hydraulic factors affecting flooding, document ground-water/surface-water interactions, determine the adequacy of the current freshwater supply, and determine water and sediment quality. These goals were accomplished by installing and operating a network of stream-gaging stations, meteorology stations, and shallow ground-water piezometers, by computing water budgets for the two Refuge units, and by sampling and analyzing water and pond-bottom sediments for major ions, trace metals, and organic compounds. Streamflow during the study was dominated by winter stormflows, followed by a gradual recession of flow into summer 1997, as water that had been stored in alluvial fans drained to lowland ditches. Outflow at the ditch terminus in 1997 was 125 million gallons greater than measured inflow to the coastal plain, mainly reflecting gains from ground water along the ditches between outlying gages and the ditch terminus. Of the measured 1997 outflow, 98 percent

    The O'OTEC geologic survey provides the following points of information concerning development of the OTEC facilities of the Kahe Point: (1) the 1000 m isobath lies in the landward half of a gently sloping (10 to 20% grade) plateau that is generally sediment covered. The plateau extends as much as 15 km from the coast to a water depth of 1600 m. Although the plateau sediment cover locally displays a morphology and internal structure indicative of submarine sliding, or other types of mass movement, the age of movement or extent of internal disruption is not known. Thus, the geotechnical studies (Part B of this report by Winters and Lee) on the sediments recovered provide the only direct evaluation of the engineering properties of this sediment cover. (2) The more gently sloping plateau is separated from the shelf and coastal area by a steeper (30 to 90% grade) narrow slope that appears relatively free of sediment cover resolvable by acoustic profiling south of Maili Point. (3) The distribution of sediment type as mapped with the acoustic-reflection profiles does not show a simple relation to volcanic bedrock relief. The bathymetry basically reflects the volcanic surface because the resolvable sediment cover is generally less than 35 m.

    Fossil pollen from a 3.5 m-long core from Ka'au Crater, Hawaii (elev. 460 m), yields a ca. 23,000-year record of regional vegetation history. Results indicate a full-glacial period drier and possibly cooler than present, a warmer and wetter early Holocene, and a somewhat drier late Holocene; this sequence agrees with earlier work by Selling (1948) on other islands. The oldest zone is donated by pollen of Chenopodium oahuense, Acacia koa, and Dodonaea viscosa; post-glacial pollen assemblages feature high percentages of Myrsine and Coprosma, followed by increases in Lycopodium cernuum Ilex anomala. Freycinetia arborea and Pritchardia. After about 8000 years ago, Chenopodium, Acacia, and Dodonaea increase, suggesting a return to drier conditions. Abundant pollen of Chenopodium oahuense, a plant of dry regions, during the last glacial maximum implies that neither the trade winds nor cyclonic storms were delivering as much moisture to the regional vegetation as they presently do. This suggests that the ocean surface temperature during the last glacial maximum may have been cooler than present, a finding contradictory to the reconstructions of the CLIMAP (1981) group, which show temperatures near Hawaii equal to or even warmer than present.

    2003-12-01

    During ODP Leg 200 in December, 2002, a series of thinly bedded volcaniclastic turbidites and silty muds interbedded with two thicker and strongly indurated vitric tuffs was drilled at Site 1223 on the crest of the Hawaiian arch east of the island of Oahu. The massive Nu`uanu landslide debris field, derived from a massive collapse of the eastern half of Oahu at about 2 Ma, lies in the flexural moat between the site and the island. The shipboard interpretation (1) was that the muds and silts are typical turbidites derived by redeposition from beaches and nearshore benches, but that the tuffs represent the distal portions of large submarine pyroclastic eruptions that may have attended the landslide. We report electron probe microanalyses of basaltic glass, olivine, Cr-spinel, palagonite and secondary minerals in the tuffs supporting the shipboard interpretation. In particular, the glass compositions from individual thin sections match precisely the range of compositions obtained from numerous samples of coarse volcaniclastic breccia sampled from the steep flanks of landslide blocks in the moat (2). This includes somewhat higher SiO2 and lower total iron as FeO(T) at given MgO than similar basaltic glasses from other Hawaiian volcanoes, a distinctive attribute of tholeiitic basalt from Oahu's Ko`olau volcano. Key attributes of the glasses in the tuffs and the minerals in them are that they are poly-compositional and they are strongly differentiated, with a range of compositions typical of those erupted from modern Hawaiian volcanic rift systems supplied by lateral diking from central conduits. The finer-grained tuffs at Site 1223 thus are indeed a distal pyroclastic facies that seemingly tapped much of the suddenly exposed, magma-inflated, deep flanking rift system of Ko`olau volcano. Over-steepening of the NE flank of the volcano coupled with internal weakening provided by near saturation of its rift system with magma may have triggered the landslide. This was almost

    High-resolution measurements of waves, currents, water levels, temperature, salinity and turbidity were made in Maunalua Bay, southern Oahu, Hawaii, during the 2008-2009 winter to better understand coastal circulation, water-column properties, and sediment dynamics during a range of conditions (trade winds, kona storms, relaxation of trade winds, and south swells). A series of bottom-mounted instrument packages were deployed in water depths of 20 m or less to collect long-term, high-resolution measurements of waves, currents, water levels, temperature, salinity, and turbidity. These data were supplemented with a series of profiles through the water column to characterize the vertical and spatial variability in water-column properties within the bay. These measurements support the ongoing process studies being done as part of the U.S. Geological Survey (USGS) Coastal and Marine Geology Program's Pacific Coral Reef Project; the ultimate goal of these studies is to better understand the transport mechanisms of sediment, larvae, pollutants, and other particles in coral reef settings. Project Objectives The objective of this study was to understand the temporal variations in currents, waves, tides, temperature, salinity and turbidity within a coral-lined embayment that receives periodic discharges of freshwater and sediment from multiple terrestrial sources in the Maunalua Bay. Instrument packages were deployed for a three-month period during the 2008-2009 winter and a series of vertical profiles were collected in November 2008, and again in February 2009, to characterize water-column properties within the bay. Measurements of flow and water-column properties in Maunalua Bay provided insight into the potential fate of terrestrial sediment, nutrient, or contaminant delivered to the marine environment and coral larval transport within the embayment. Such data are useful for providing baseline information for future watershed decisions and for establishing guidelines for

    SciTech Connect

    1995-10-01

    This section describes the ambient (surrounding) air quality of the TVA region, discusses TVA emission contributions to ambient air quality, and identifies air quality impacts to human health and welfare. Volume 2 Technical Document 2, Environmental Consequences, describes how changes in TVA emissions could affect regional air quality, human health, environmental resources, and materials. The primary region of the affected environment is broadly defined as the state of Tennessee, as well as southern Kentucky, western Virginia, southern West Virginia, western North Carolina, and northern Georgia, Alabama, and Mississippi. This area represents the watershed of the Tennessee River and the 201 counties of the greater TVA service area. Emissions from outside the Tennessee Valley region contribute to air quality in the Valley. Also, TVA emissions are transported outside the Valley and have some impact on air quality beyond the primary study area. Although the study area experiences a number of air quality problems, overall air quality is good.

  11. Food-related Beliefs of Adolescent Girls Ages 9-13 and Their Mothers on O'ahu, Hawai'i.

    A number of factors contribute to the development of obesity in adolescents, including various dietary and lifestyle behaviors, and a host of social and environmental factors, such as socioeconomic status, parental education, and culture. Research examining beliefs about behaviors related to weight status in adolescents, such as food intake, can create a better understanding of risk factors for obesity. This study explored beliefs about behaviors related to weight status in 20 early adolescent girls aged 9 to 13 years and their mothers in O'ahu, Hawai'i. Semi-structured individual interviews were conducted to elucidate beliefs through discussion of food purchasing, feeding practices, portion control strategies, eating outside the home, and body size perception. Interviews were transcribed verbatim and examined using directed content analysis. Both mothers and daughters believed that diets should consist of fresh foods and be based on principles of variety, balance, and moderation, and had negative perceptions of school lunch. In describing ideal body size, mothers expressed greater concern for overweight, as well as ethno-cultural beauty standards, than daughters. Mothers believed daughters should have a positive relationship with food but also applied various portion control strategies with them. Findings reveal how mothers' and daughters' beliefs may influence daily food-related practices in adolescent girls. Future studies may seek to investigate the role these factors may play in determining weight status in adolescents in Hawai'i, with findings to be used to inform health promotion programs.

  12. Relations between Land Use and Organochlorine Pesticides, PCBs, and Semi-Volatile Organic Compounds in Streambed Sediment and Fish on the Island of Oahu, Hawaii

    USGS Publications Warehouse

    Brasher, A.M.D.; Wolff, R.H.

    2004-01-01

    Bed-sediment and/or fish samples were collected from 27 sites around the island of Oahu (representing urban, agricultural, mixed, and forested land use) to determine the occurrence and distribution of hydrophobic organic compounds including organochlorine pesticides, polychlorinated biphenyls (PCBs), and semi-volatile organic compounds (SVOCs). Of the 28 organochlorine compounds analyzed in the fish, 14 were detected during this study. Nineteen of the 31 organochlorine compounds and 40 of the 65 SVOCs were detected in the sediment. Urban sites had the highest number of detections and tended to have the highest concentrations of pesticides. Chlordane compounds were the most frequently detected constituents at urban sites, followed by dieldrin, polycyclic aromatic hydrocarbons (PAHs), and DDT compounds. PAHs were the most frequently detected constituents in watersheds with mixed (urban and agricultural) land use. The only pesticides detected at agricultural sites were DDT and its degradation products, DDD and DDE. No pesticides or PCBs were detected at the forested sites, but a few ubiquitous SVOCs were found in sediments at some forested sites. In general, concentrations of the most frequently detected pesticides were higher in fish than in sediment. Following a trend that has been observed elsewhere in the nation, concentrations of most organochlorine pesticides and PCBs are decreasing in Hawaii.

  13. Analysis of High-Penetration Levels of Photovoltaics into the Distribution Grid on Oahu, Hawaii: Detailed Analysis of HECO Feeder WF1

    2013-05-01

    Renewable generation is growing at a rapid rate due to the incentives available and the aggressive renewable portfolio standard targets implemented by state governments. Distributed generation in particular is seeing the fastest growth among renewable energy projects, and is directly related to the incentives. Hawaii has the highest electricity costs in the country due to the high percentage of oil burning steam generation, and therefore has some of the highest penetration of distributed PV in the nation. The High Penetration PV project on Oahu aims to understand the effects of high penetration PV on the distribution level, to identify penetration levels creating disturbances on the circuit, and to offer mitigating solutions based on model results. Power flow models are validated using data collected from solar resources and load monitors deployed throughout the circuit. Existing interconnection methods and standards are evaluated in these emerging high penetration scenarios. A key finding is a shift in the level of detail to be considered and moving away from steady-state peak time analysis towards dynamic and time varying simulations. Each level of normal interconnection study is evaluated and enhanced to a new level of detail, allowing full understanding of each issue.

  14. Microfossil assemblages on Tuscaloosa Seamount and their constraints on the age of the Nu´uanu landslide, north of Oahu, HI

    NASA Astrophysics Data System (ADS)

    Morgan, Julia K.; Resig, Johanna M.; Siesser, William G.

    2006-03-01

    The Núuanu submarine landslide, north of the Island of Oahu, is the largest of many debris avalanches along the flanks of the Hawaiian Islands. Several attempts have been made to date the Núuanu landslide and to assess its relationship to the shield-building stage of Kóolau Volcano as an indication of hazards that might be anticipated during the evolution of oceanic volcanoes. Previous age determinations based on magnetostratigraphy and the temporal distribution of turbidites have yielded a range of possible ages. We describe a distinctive fine-grained silty mudstone representing mantling sediment on the largest landslide block within the debris field, Tuscaloosa Seamount. This mudstone contains foraminifera and nannofossil assemblages that yield a micropaleontological age and paleoenvironmental determination for the interval immediately following landslide emplacement. The microfossils constrain the mantling sediment to have been deposited between 2.5 and 3.3 Ma, in offshore, mid- to lower-bathyal (˜1500-3000 m) water depth, consistent with a position on the upper flanks of Tuscaloosa Seamount. These findings indicate that landsliding occurred prior to or near the end of shield building at Kóolau Volcano (2.9 Ma), and may have precipitated dramatic changes in volcano growth and deformation behavior, as well as changes in basalt geochemistry.

    2008-03-31

    National Orange Show Photovoltaic Demonstration created a 400KW Photovoltaic self-generation plant at the National Orange Show Events Center (NOS). The NOS owns a 120-acre state fairground where it operates an events center and produces an annual citrus fair known as the Orange Show. The NOS governing board wanted to employ cost-saving programs for annual energy expenses. It is hoped the Photovoltaic program will result in overall savings for the NOS, help reduce the State's energy demands as relating to electrical power consumption, improve quality of life within the affected grid area as well as increase the energy efficiency of buildings at our venue. In addition, the potential to reduce operational expenses would have a tremendous effect on the ability of the NOS to service its community.

    TThe figure above depicts how much air temperatures near the Earth's surface changed relative to the global mean temperature from 1951 to 1980. NASA researchers used maps of urban areas derived from city lights data to account for the 'heat island' effect of cities. The red and orange colors show that temperatures are warmer in most regions of the world when compared to the 1951 to 1980 'normal' temperatures. Warming around the world has been widespread, but it is not present everywhere. The largest warming is in Northern Canada, Alaska and Siberia, as indicated by the deeper red colors. The lower 48 United States have become warmer recently, but only enough to make the temperatures comparable to what they were in the 1930s. The scale on the bottom of these temperature anomaly images represent degrees in Celsius. The negative numbers represent cooling and the positive numbers depict warming. Overall, the air temperature near the Earth's surface has warmed by 1oF (0.6oC) globally, on average, over the last century.

    The upper left image in this display is from the panoramic camera on the Mars Exploration Rover Spirit, showing the 'Magic Carpet' region near the rover at Gusev Crater, Mars, on Sol 7, the seventh martian day of its journey (Jan. 10, 2004). The lower image, also from the panoramic camera, is a monochrome (single filter) image of a rock in the 'Magic Carpet' area. Note that colored portions of the rock correlate with extracted spectra shown in the plot to the side. Four different types of materials are shown: the rock itself, the soil in front of the rock, some brighter soil on top of the rock, and some dust that has collected in small recesses on the rock face ('spots'). Each color on the spectra matches a line on the graph, showing how the panoramic camera's different colored filters are used to broadly assess the varying mineral compositions of martian rocks and soils.

    Interstitial emphysema and pulmonic hemorrhage alone are not the causes of pulmonic air embolism. The conditions making the entrance of air from the lungs to the vessels of pulmonary circulation are obviously present only if the expiration pressure is suddenly strongly elevated. Based on this point of view, investigations were performed in autopsy cases--falls from a height, being run over, a gunshot in the abdomen. We have succeeded in proving the entrance of air into capillaries and branches of the pulmonary vein. The precipitation of thrombocytes at the margin of large air bubbles in pulmonary veins shows the finding of air in the vessels as a vital or supravital reaction. PMID:4090761

    2016-07-11

    Sensitivity to variability in resources has been documented in humans, primates, birds, and social insects, but the fit between empirical results and the predictions of risk sensitivity theory (RST), which aims to explain this sensitivity in adaptive terms, is weak [1]. RST predicts that agents should switch between risk proneness and risk aversion depending on state and circumstances, especially according to the richness of the least variable option [2]. Unrealistic assumptions about agents' information processing mechanisms and poor knowledge of the extent to which variability imposes specific selection in nature are strong candidates to explain the gap between theory and data. RST's rationale also applies to plants, where it has not hitherto been tested. Given the differences between animals' and plants' information processing mechanisms, such tests should help unravel the conflicts between theory and data. Measuring root growth allocation by split-root pea plants, we show that they favor variability when mean nutrient levels are low and the opposite when they are high, supporting the most widespread RST prediction. However, the combination of non-linear effects of nitrogen availability at local and systemic levels may explain some of these effects as a consequence of mechanisms not necessarily evolved to cope with variance [3, 4]. This resembles animal examples in which properties of perception and learning cause risk sensitivity even though they are not risk adaptations [5]. PMID:27374342

  8. Casimir experiments showing saturation effects

    We address several different Casimir experiments where theory and experiment disagree. First out is the classical Casimir force measurement between two metal half spaces; here both in the form of the torsion pendulum experiment by Lamoreaux and in the form of the Casimir pressure measurement between a gold sphere and a gold plate as performed by Decca et al.; theory predicts a large negative thermal correction, absent in the high precision experiments. The third experiment is the measurement of the Casimir force between a metal plate and a laser irradiated semiconductor membrane as performed by Chen et al.; the change in force with laser intensity is larger than predicted by theory. The fourth experiment is the measurement of the Casimir force between an atom and a wall in the form of the measurement by Obrecht et al. of the change in oscillation frequency of a {sup 87}Rb Bose-Einstein condensate trapped to a fused silica wall; the change is smaller than predicted by theory. We show that saturation effects can explain the discrepancies between theory and experiment observed in all these cases.

  9. Numerical Simulation of Regional Changes in Ground-Water Levels and in the Freshwater-Saltwater Interface Induced by Increased Pumpage at Barbers Point Shaft, Oahu, Hawaii

    1995-01-01

    The effect on the regional ground-water system of southern Oahu from increased pumpage at Barbers Point shaft was estimated by a numerical ground-water model developed for the Oahu Regional Aquifer Systems Analysis (RASA) study. The RASA model was updated by revising pumping and ground-water recharge data. Pumpage data used in the new simulations were based on the allocated pumping rates for 1995 as set by the State Commission on Water Resource Management. On the basis of numerical simulation, Barbers Point shaft can sustain a withdrawal rate of 4.34 million gallons per day without adversely affecting wells in the Waianae aquifer. From results of numerical simulations, it is estimated that, as a result of increasing pumpage in Barbers Point shaft by 2 million gallons per day above the 1995-allocated rate of 2.337 million gallons per day, regional declines in ground-water levels will be about 0.4 to 0.7 feet throughout the Waianae aquifer and about 0.8 ft at the shaft. The corresponding rise of the freshwater-saltwater interface, as a result of declines in ground-water levels, is estimated to be about 20 to 30 feet. Numerical simulation also indicates that changes in ground-water levels greater than about 0.1 feet do not extend across either the Waianae-Koolau unconformity or the south Schofield barrier. The model-estimated position of the freshwater-saltwater interface, as a result of additional pumpage, ranges from 500 to 860 feet below sea level in the southern and northern parts of the aquifer, respectively, and about 540 feet below sea level at the shaft. On the basis of an estimate of the thickness of the transition-zone, the freshwater lens would remain about 240 feet thick below the shaft. In addition, the estimated declines in ground-water levels throughout the aquifer are small compared with the thickness of the freshwater lens and these declines would not be expected to affect the yields of other wells in terms of quantity.

    Nutrient pollution of coastal waters commonly arises from terrestrial non-point sources of N and P such as on-site disposal systems (OSDS) and fertilizer leachate. Elevated nutrient loading of submarine groundwater discharge (SGD) has been documented in the western edge of Maunalua Bay, Oahu, an area with high OSDS density. We examined coastal groundwater and nearshore marine water quality in two adjacent aquifers (Waialae West and Waialae East) within the study region with differing land-use and hydrogeological characteristics to better understand 1) the spatial variability of SGD nutrient and water fluxes and 2) the reasons for this spatial variability. Nutrient concentrations and NO3- stable isotope ratios were measured in coastal and terrestrial groundwater as well as nearshore marine water and integrated with SGD flux, land-use, and recharge data to examine potential nutrient sources in each aquifer. Regionally-elevated NO3- concentrations (169 µM) and δ15N-NO3- values (10.9 ‰) were apparent in SGD in the Waialae West Aquifer where OSDS density is highest. Coastal sites sampled in the neighboring Waialae East Aquifer exhibited significantly lower values for these parameters, with δ15N-NO3- values ranging from 5.7 - 5.9‰ and NO3- concentrations from 43 - 69 µM. The isotopic composition of NO3- in SGD originating from the Waialae West Aquifer was primarily influenced by mixing of a wastewater source, with wastewater effluent accounting for nearly 4.4% of total recharge and 79 - 97% of total N and P loads within the aquifer. These findings illustrate the utility of synthesizing nutrient concentrations and stable isotope parameters together with SGD flux determination, and aquifer-scale land-use and recharge data in determining the contribution of terrestrial sources to coastal nutrient loading via SGD.

    Still images from a towed camera sled were used to evaluate the potential ecological effects of M47A2 mustard-filled (1,1‧-thiobis[2-chloroethane]) bombs disposed of in over 500 m of water off the south coast of Oahu in 1944. The types of munitions and munitions debris in the images were identified by an ordnance and explosives safety specialist. To the extent feasible, non-munitions related debris were also identified. Biologists then examined the images and identified the types and numbers of animals: (1) on or near (<1 m) the M47A2 bombs; (2) on other manmade debris, including other munitions; and (3) on the natural substrate that was predominantly sediment with little, if any, topographic relief. Multivariate statistical techniques were used to analyze these data to identify differences between the biota inhabiting the three substrates. The analysis indicated that the types and numbers of animals associated with the M47A2 bombs were not significantly different from those observed on other types of munitions and other manmade debris; however they were significantly different from the animals found only on the natural sediment. Based on these results, it appears that the mustard-filled bombs are providing hard substrate similar to other disposed objects, attracting "hard substrate species" that would not have otherwise colonized the area. Even though it is apparent that many of the mustard-filled bombs have breached and their contents exposed, the analysis did not find any evidence of animals avoiding the mustard-filled bombs.

    Concern over potential effects from construction of the H-3 highway on Oahu, Hawaii, prompted a long-term study of streamflow and suspended-sediment transport at a network of five stream-gaging stations along the highway route. This report presents results for 1983-91, which included pre-construction and construction periods at all stream-gaging stations. Annual rainfall, streamflow, and suspended-sediment loads were generally higher during construction than before construction. Data collected before and during construction were compared using analysis of covariance to determine whether streamflow and suspended-sediment loads changed significantly during construction after accounting for effects of increased rainfall. Streamflow at stream-gaging stations was compared with streamflow at an index stream-gaging station unaffected by construction. Streamflow data were divided into low- and high-flow classes, and the two flow classes were analyzed separately. Low flows increased 117 percent during construction at one station. This increase probably was related to the removal of vegetation for highway construction. Low flows decreased 28 percent at another station, probably as a result of increased ground-water withdrawals and highway construction activities. No significant changes in low flows were detected at the other stations, and no significant changes in high flows were detected at any stations. Suspended-sediment loads increased significantly during construction at three stations. Highway construction contributed between 56 and 76 percent of the suspended-sediment loads measured at these stations during construction. Loads did not change significantly at a station downstream of a reservoir, and loads decreased at a station downstream of a drainage basin that was heavily used for agriculture before construction. Suspended-sediment concentrations were used to assess compliance with applicable State water-quality standards. State water-quality standards for suspended

    Shoreward pulses of cold, high salinity, phytoplankton-rich bottom water represent short time scale changes in nearshore hydrography and biological community structure off the leeward coast of Oahu, Hawaii. A three-week mooring deployment in Spring 2009 revealed that 'cold pulses' occurred over all phases of the semidiurnal surface tide, but that a statistically greater proportion occurred at low slack tide, when the typically along-shore flow rotated and briefly exhibited a more dominant onshore component. Cold pulses were more frequent and propagated farther shoreward when background water-column stratification increased. Targeted shipboard sampling of a cold pulse in Spring 2010 revealed that chlorophyll fluorescence within the cold pulse was 7 standard deviations higher than the 11-h mean outside the cold pulse, phytoplankton concentrations (cells mL-1) were up to a factor of 3 higher within the cold pulse, and phytoplankton entrained within the cold pulse were adapted to habitats with lower light levels and higher nutrient concentrations compared to ambient waters. Analysis of multi-frequency acoustic data collected during two shipboard surveys in 2009 and 2010 indicated that acoustic scattering during cold pulses was predominantly biological, dominated by 1.0-1.5 mm spheroid fluid-like scatterers, both in the waters above the cold pulse and in a strong-scattering feature at the cold-pulse interface. These aggregations of larger organisms at the cold-pulse interface did not appear to migrate downwards into the phytoplankton-rich water during the active passage of the cold pulse. Observations of similar temperature events throughout the tropical Pacific, combined with our multidisciplinary findings, suggest that pulsed deliveries of phytoplankton-rich water to nearshore habitats may be regular occurrences throughout the North Pacific Subtropical Gyre.

    1996-06-01

    In this paper, uncertainty in recharge estimates is investigated relative to its impact on assessments of groundwater contamination vulnerability using a relatively simple pesticide mobility index, attenuation factor (AF). We employ a combination of first-order uncertainty analysis (FOUA) and sensitivity analysis to investigate recharge uncertainties for agricultural land on the island of O'ahu, Hawai'i, that is currently, or has been in the past, under sugarcane or pineapple cultivation. Uncertainty in recharge due to recharge component uncertainties is 49% of the mean for sugarcane and 58% of the mean for pineapple. The components contributing the largest amounts of uncertainty to the recharge estimate are irrigation in the case of sugarcane and precipitation in the case of pineapple. For a suite of pesticides formerly or currently used in the region, the contribution to AF uncertainty of recharge uncertainty was compared with the contributions of other AF components: retardation factor (RF), a measure of the effects of sorption; soil-water content at field capacity (ΘFC); and pesticide half-life (t1/2). Depending upon the pesticide, the contribution of recharge to uncertainty ranks second or third among the four AF components tested. The natural temporal variability of recharge is another source of uncertainty in AF, because the index is calculated using the time-averaged recharge rate. Relative to the mean, recharge variability is 10%, 44%, and 176% for the annual, monthly, and daily time scales, respectively, under sugarcane, and 31%, 112%, and 344%, respectively, under pineapple. In general, uncertainty in AF associated with temporal variability in recharge at all time scales exceeds AF. For chemicals such as atrazine or diuron under sugarcane, and atrazine or bromacil under pineapple, the range of AF uncertainty due to temporal variability in recharge encompasses significantly higher levels of leaching potential at some locations than that indicated by the

    2009-01-01

    Baseflow and storm runoff fluxes of water, suspended particulate matter (SPM), and nutrients (N and P) were assessed in conservation, urban, and agricultural streams discharging to coastal waters around the tropical island of Oahu, Hawai'i. Despite unusually low storm frequency and intensity during the study, storms accounted for 8-77% (median 30%) of discharge, 57-99% (median 93%) of SPM fluxes, 11-79% (median 36%) of dissolved nutrient fluxes and 52-99% (median 85%) of particulate nutrient fluxes to coastal waters. Fluvial nutrient concentrations varied with hydrologic conditions and land use; land use also affected water and particulate fluxes at some sites. Reactive dissolved N:P ratios typically were ???16 (the 'Redfield ratio' for marine phytoplankton), indicating that inputs could support new production by coastal phytoplankton, but uptake of dissolved nutrients is probably inefficient due to rapid dilution and export of fluvial dissolved inputs. Particulate N and P fluxes were similar to or larger than dissolved fluxes at all sites (median 49% of total nitrogen, range 22-82%; median 69% of total phosphorus, range 49-93%). Impacts of particulate nutrients on coastal ecosystems will depend on how efficiently SPM is retained in nearshore areas, and on the timing and degree of transformation to reactive dissolved forms. Nevertheless, the magnitude of particulate nutrient fluxes suggests that they represent a significant nutrient source for many coastal ecosystems over relatively long time scales (weeks-years), and that reductions in particulate nutrient loading actually may have negative impacts on some coastal ecosystems.

  18. Mimas Showing False Colors #1

    NASA Technical Reports Server (NTRS)

    2005-01-01

    False color images of Saturn's moon, Mimas, reveal variation in either the composition or texture across its surface.

    During its approach to Mimas on Aug. 2, 2005, the Cassini spacecraft narrow-angle camera obtained multi-spectral views of the moon from a range of 228,000 kilometers (142,500 miles).

    The image at the left is a narrow angle clear-filter image, which was separately processed to enhance the contrast in brightness and sharpness of visible features. The image at the right is a color composite of narrow-angle ultraviolet, green, infrared and clear filter images, which have been specially processed to accentuate subtle changes in the spectral properties of Mimas' surface materials. To create this view, three color images (ultraviolet, green and infrared) were combined into a single black and white picture that isolates and maps regional color differences. This 'color map' was then superimposed over the clear-filter image at the left.

    The combination of color map and brightness image shows how the color differences across the Mimas surface materials are tied to geological features. Shades of blue and violet in the image at the right are used to identify surface materials that are bluer in color and have a weaker infrared brightness than average Mimas materials, which are represented by green.

    Herschel crater, a 140-kilometer-wide (88-mile) impact feature with a prominent central peak, is visible in the upper right of each image. The unusual bluer materials are seen to broadly surround Herschel crater. However, the bluer material is not uniformly distributed in and around the crater. Instead, it appears to be concentrated on the outside of the crater and more to the west than to the north or south. The origin of the color differences is not yet understood. It may represent ejecta material that was excavated from inside Mimas when the Herschel impact occurred. The bluer color of these materials may be caused by subtle differences in

    Vehicle emissions are responsible for a considerable share of urban air pollution concentrations. The traffic air quality index (TAQI) is proposed as a useful tool for evaluating air quality near roadways. The TAQI associates air quality with the equivalent emission from traffic sources and with street structure (roadway structure) as anthropogenic factors. The paper presents a method of determining the TAQI and defines the degrees of harmfulness of emitted pollution. It proposes a classification specifying a potential threat to human health based on the TAQI value and shows an example of calculating the TAQI value for real urban streets. It also considers the role that car traffic plays in creating a local UHI. PMID:25461063

    New paleomagnetic measurements (directions and paleointensity determinations), coupled with precise 40Ar/39Ar radioisotopic dating, are revolutionizing our understanding of the geodynamo by providing detailed terrestrial lava records of the short-term behavior of the paleomagnetic field. As part of an investigation of the evolution of Koolau Volcano (one of the volcanoes comprising Oahu Island) and the short-term behavior of the geomagnetic field, we have sampled a long volcanic section located on the buttressed flank of the volcano within Halawa Valley. Prior paleomagnetic and K-Ar investigations of the Koolau (Volcano) Series revealed excursional directions (Site F of Doell and Dalrymple, 1973). The alkaline composition of lava flows, easy access, and close geographical proximity to K-Ar dated lava flows made this newly studied 120 m thick sequence of flows in Halawa valley an excellent candidate for detailed paleomagnetic analysis. At least eight samples collected from each of 28 successive flow-sites were stepwise demagnetized by both alternating field (5mT to 100mT) and thermal (from 28o C to 575-650oC) methods, and the mean directions obtained by principal component analysis. All samples yielded a strong and stable ChRM trending towards the origin based on no less than seven to nine steps, with thermal and AF results agreeing to a very high degree. Low field susceptibility versus temperature (k-T) analyses were conducted for individual lava flows, and the majority of them show reversible curves. Curie point determinations revealed a temperature close to or equal to 580oC, indicative of almost pure magnetite for most of the flows. Magnetic grain sizes analysis indicated SD-PSD sizes. The mean directions of magnetization of the entire section sampled indicate that about 10 m of the section are characterized by excursional directions (5 lava flows). In addition to the directional analyses we performed absolute paleointensity determinations on the 28 lavas

  3. Development of cold seawater air conditioning systems for application as a demand side management tool for Hawaii and other subtropical climates

    SciTech Connect

    Kaya, M.H.

    1996-10-01

    Because of the proximity to deep cold seawater for many coastal regions in Hawaii and the high demand for air conditioning in large buildings, seawater air conditioning (SWAC) is a major potential sustainable energy resource for Hawaii and other subtropical regions of the world. The basic concept of seawater air conditioning is the use deep cold seawater to cool the chilled water in one or more air conditioned buildings as opposed to using energy intensive refrigeration systems. The economic viability of the seawater air conditioning is determined by comparing the construction and operating costs of the seawater supply system to the construction and operating costs of conventional air conditioning systems. The State of Hawaii commissioned an analysis to identify the technical and economic opportunities and limitations in the use of SWAC in Hawaii. The result of this work is a feasibility analysis of SWAC systems in the state and the potential associated energy savings. The study looked at the prospects of installing such a system at a major new resort development on Oahu called West Beach.

  4. Air surveillance

    SciTech Connect

    Patton, G.W.

    1995-06-01

    This section of the 1994 Hanford Site Environmental Report summarizes the air surveillance and monitoring programs currently in operation at that Hanford Site. Atmospheric releases of pollutants from Hanford to the surrounding region are a potential source of human exposure. For that reason, both radioactive and nonradioactive materials in air are monitored at a number of locations. The influence of Hanford emissions on local radionuclide concentrations was evaluated by comparing concentrations measured at distant locations within the region to concentrations measured at the Site perimeter. This section discusses sample collection, analytical methods, and the results of the Hanford air surveillance program. A complete listing of all analytical results summarized in this section is reported separately by Bisping (1995).

  5. Volatile-Rich Mineral Phases in the Hawaiian Lithosphere: Phlogopites and Carbonates in 0-age Garnet Pyroxenite Xenoliths From Salt Lake Crater, (Oahu, Hawaii).

    NASA Astrophysics Data System (ADS)

    Bizimis, M.; Sen, G.; Salters, V. J.

    2003-12-01

    We present the first detailed Hf, Nd, Sr isotope and trace and major element investigation on clinopyroxene (cpx), garnet, phlogopite and carbonate mineral separates from garnet pyroxenite xenoliths from the Salt Lake crater, Oahu, Hawaii. These xenoliths are brought to the surface by the post-erosional lavas that mark the last stage of the evolution of a Hawaiian volcano. Previous studies have suggested that these pyroxenites are either high pressure cumulates associated with the Honolulu volcanics (HV) post erosional lavas, or MORB-related cumulates at a 80-100 Ma paleo ridge. In both Nd-Hf and Nd-Sr isotope spaces all cpx and garnet data are within the range of the HV and other Hawaiian post-erosional lavas. The Lu-Hf and Sm-Nd isotope systematics of the cpx - garnet pairs give essentially 0 ages, providing the first direct evidence that these garnet pyroxenites are indeed 0-age high pressure cumulates from melts isotopically similar to the HVs. Some 0-age pyroxenites also contain veins with volatile-rich mineral assemblages (phlogopite, carbonates and associated glass pockets), that have infiltrated and reacted with the cpx-garnet matrix. These phlogopites have identical 143Nd/144Nd ratios as the cpx (0.51303) but significantly more radiogenic 87Sr/86Sr (0.7032 - 0.7033 in cpx, 0.70365 - 0.70385 in phlogopites, carbonates and glass). These minerals have higher 87Sr/86Sr (for a given 143Nd/144Nd) than MORBs or HVs and fall at the extension of the horizontal displacement of the post shield and post erosional Hawaiian lavas from the Pacific MORB field in Nd-Sr isotope space. Isotopically then, these volatile phases are more similar to the post-erosional lavas than the shield (Koolau) tholeites, providing new evidence for the involvement of volatiles in the generation of the post-erosional volcanism. The association of these volatile-rich phases with garnet pyroxenites and their absence in the more shallow, spinel peridotites points to a deep (i.e. non

  6. Flood-Frequency Estimates for Streams on Kaua`i, O`ahu, Moloka`i, Maui, and Hawai`i, State of Hawai`i

    2010-01-01

    This study provides an updated analysis of the magnitude and frequency of peak stream discharges in Hawai`i. Annual peak-discharge data collected by the U.S. Geological Survey during and before water year 2008 (ending September 30, 2008) at stream-gaging stations were analyzed. The existing generalized-skew value for the State of Hawai`i was retained, although three methods were used to evaluate whether an update was needed. Regional regression equations were developed for peak discharges with 2-, 5-, 10-, 25-, 50-, 100-, and 500-year recurrence intervals for unregulated streams (those for which peak discharges are not affected to a large extent by upstream reservoirs, dams, diversions, or other structures) in areas with less than 20 percent combined medium- and high-intensity development on Kaua`i, O`ahu, Moloka`i, Maui, and Hawai`i. The generalized-least-squares (GLS) regression equations relate peak stream discharge to quantified basin characteristics (for example, drainage-basin area and mean annual rainfall) that were determined using geographic information system (GIS) methods. Each of the islands of Kaua`i,O`ahu, Moloka`i, Maui, and Hawai`i was divided into two regions, generally corresponding to a wet region and a dry region. Unique peak-discharge regression equations were developed for each region. The regression equations developed for this study have standard errors of prediction ranging from 16 to 620 percent. Standard errors of prediction are greatest for regression equations developed for leeward Moloka`i and southern Hawai`i. In general, estimated 100-year peak discharges from this study are lower than those from previous studies, which may reflect the longer periods of record used in this study. Each regression equation is valid within the range of values of the explanatory variables used to develop the equation. The regression equations were developed using peak-discharge data from streams that are mainly unregulated, and they should not be used to

  18. Fostering Earth Science Inquiry From Within a Native Hawaiian Cultural Framework In O`ahu (Hawai`i) Through A Multidisciplinary Place-Based High School Summer Enrichment Program

    NASA Astrophysics Data System (ADS)

    Moxey, L.; Dias, R.; Legaspi, E.

    2010-12-01

    During the summer of 2010, twenty-five public high school students from underrepresented communities and ethnicities (Hawaiian, part-Hawaiian, Sāmoan, Filipino, Pacific Islander) in O`ahu (Hawai`i) participated in the Mālama Ke Ahupua`a (protecting our watershed) program. This rigorous three-week hands-on, place-based multidisciplinary program provided students with the opportunity of visiting the Mānoa Valley watershed (O`ahu, Hawaii) for learning and experiencing the Earth Science System dynamics that comprises it, while simultaneously exploring the significance of the ahupua`a (watershed) as related to native Hawaiian history and culture. While earning Hawaii DOE-approved academic credit, students utilized GPS/GIS technology, quantitative water quality testing equipment, and environmental monitoring tools for performing a watershed survey and water quality study of Mānoa Stream (Mānoa Valley) from its inception in the mountains, its advance through Honolulu’s urbanized areas, and its convergence with the Pacific Ocean. Through this hands-on field-based study, students documented changes in the watershed’s environment as reflected in declining water quality induced by anthropogenic pollution sources and urbanization. Students also visited relevant native Hawaiian cultural sites in Mānoa, and explored their direct links with the historical sustainable usage of the watershed’s natural resources, both from a cultural and science-based perspective. Finally, traditional wa`a (native Hawaiian outrigger canoes) were used as both cultural resources for discussing ancient Polynesian exploration, as well as scientific research platforms for conducting near-shore reef surveys & assessments. This program served to promote not only Earth Science literacy and STEM skills, but also contributed to further environmental stewardship while fostering native Hawaiian & Polynesian cultural identities.

    Short-term exposure to particulate matter (PM) air pollution is associated with an increased cardiovascular mortality. Chronic exposure to PM is also associated with cardiovascular risk. Myocardial infarction and heart failure are the most common cardiovascular events associated with PM pollution. The pathophysiological mechanisms related to PM pollution are inflammation, thrombosis, vasomotion abnormalities, progression of atherosclerosis, increased blood pressure, and cardiac remodeling. A decrease in PM exposure may be particularly beneficial in subjects with a high cardiovascular risk. PMID:26547674

    New paleomagnetic measurements, coupled with Argon-Argon ( 40Ar/ 39Ar) radioisotopic dating, are revolutionizing our understanding of the geodynamo by providing detailed terrestrial lava records of the short-term behavior of the paleomagnetic field. As part of an investigation of the Koolau Volcano, Oahu, and the short-term behavior of the geomagnetic field, we have sampled a long volcanic section located on the volcano's buttressed flank within Halawa Valley. Prior paleomagnetic and Potassium-Argon (K-Ar) investigations of the Koolau Volcanic Series revealed excursional directions The alkaline composition of lava flows, easy access, and close geographical proximity to K-Ar dated lava flows made this newly studied 120-m thick sequence of flows an excellent candidate for detailed paleomagnetic analysis. At least eight samples, collected from each of 28 successive flow sites, were stepwise demagnetized by both alternating field (5 mT to 100 mT) and thermal (from 28 °C to 575-650 °C) methods. Mean directions were obtained by principal component analysis. All samples yielded a strong and stable ChRM trending towards the origin of vector demagnetization diagrams based on seven or more demagnetization steps, with thermal and AF results differing insignificantly. Low-field susceptibility vs. temperature ( k- T) analysis conducted on individual lava flows indicated approximately half with reversible curves. Curie point determinations from these analyses revealed a temperature close to or equal to 580 °C, indicative of almost pure magnetite ranging from single domain (SD) to pseudosingle domain (PSD) grain sizes for most of the flows. The mean directions of magnetization of the entire section sampled indicate a reversed polarity, with ˜ 10 m of the section characterized by excursional directions (5 lava flows). The corresponding VGPs are located off the southeastern part of Africa, close to Madagascar. 40Ar/ 39Ar incremental heating experiments on groundmass from nine

  3. Effects of the H-3 Highway Stormwater Runoff on the Water Quality of Halawa Stream, Oahu, Hawaii, November 1998 to August 2004

    Wolff, Reuben H.; Wong, Michael F.

    2008-01-01

    Since November 1998, water-quality data have been collected from the H-3 Highway Storm Drain C, which collects runoff from a 4-mi-long viaduct, and from Halawa Stream on Oahu, Hawaii. From January 2001 to August 2004, data were collected from the storm drain and four stream sites in the Halawa Stream drainage basin as part of the State of Hawaii Department of Transportation Storm Water Monitoring Program. Data from the stormwater monitoring program have been published in annual reports. This report uses these water-quality data to explore how the highway storm-drain runoff affects Halawa Stream and the factors that might be controlling the water quality in the drainage basin. In general, concentrations of nutrients, total dissolved solids, and total suspended solids were lower in highway runoff from Storm Drain C than at stream sites upstream and downstream of Storm Drain C. The opposite trend was observed for most trace metals, which generally occurred in higher concentrations in the highway runoff from Storm Drain C than in the samples collected from Halawa Stream. The absolute contribution from Storm Drain C highway runoff, in terms of total storm loads, was much smaller than at stations upstream and downstream, whereas the constituent yields (the relative contribution per unit drainage basin area) at Storm Drain C were comparable to or higher than storm yields at stations upstream and downstream. Most constituent concentrations and loads in stormwater runoff increased in a downstream direction. The timing of the storm sampling is an important factor controlling constituent concentrations observed in stormwater runoff samples. Automated point samplers were used to collect grab samples during the period of increasing discharge of the storm throughout the stormflow peak and during the period of decreasing discharge of the storm, whereas manually collected grab samples were generally collected during the later stages near the end of the storm. Grab samples were

  14. Microwave and Electro-optical Transmission Experiments in the air-sea Boundary Layer

    NASA Astrophysics Data System (ADS)

    Anderson, K. D.

    2002-12-01

    Microwave and electro-optical signal propagation over a wind-roughened sea is strongly dependent on signal interaction with the sea surface, the mean profiles of pressure (P), humidity (Q), temperature (T), wind (U) and their turbulent fluctuations (p, q, t, u). Yet, within the marine surface layer, these mechanisms are not sufficiently understood nor has satisfactory data been taken to validate propagation models, especially under conditions of high seas, high winds, and large surface gradients of Q and T. To address this deficiency, the Rough Evaporation Duct (RED) experiment was designed to provide first data for validation of meteorological, microwave, and electro-optical models in the marine surface layer for rough surface conditions including the effects of surface waves. The RED experiment was conducted offshore of the Hawaiian Island of Oahu in late summer, mid-August to mid-September, of 2001. R/P FLIP, moored about 10 km off of the NE coast of Oahu, hosted the primary meteorological sensor suites and served as a terminus for the propagation links. There were eleven scientists and engineers aboard R/P FLIP who installed instruments measuring mean and turbulent meteorological quantities, sea wave heights, directions, and kinematics, upward and downward radiance, near surface bubble generation, atmospheric particle size distributions, laser probing of the atmosphere, and sources for both microwave and electro-optic signals. In addition to R/P FLIP, two land sites were instrumented with microwave and electro-optic receivers and meteorological sensors, two buoys were deployed, a small boat was instrumented, and two aircraft flew various tracks to sense both sea and atmospheric conditions. In all, more than 25 people from four countries, six universities, and four government agencies were directly involved with the RED experiment. While the overall outcome of the RED experiment is positive, we had a number of major and minor problems with the outfitting

    2015-01-01

    Background The autoimmune regulator (AIRE) is expressed in the thymus, particularly in thymic medullary epithelial cells (mTECs), and is required for the ectopic expression of a diverse range of peripheral tissue antigens by mTECs, facilitating their ability to perform negative selection of auto-reactive immature T-cells. The expression profile of peripheral tissue antigens is affected not only by AIRE deficiency but also with variation of AIRE activity in the thymus. Method and Results Therefore we screened 591bp upstream of the AIRE transcription start site including AIRE minimal promoter for single nucleotide polymorphism (SNPs) and identified two SNPs -655R (rs117557896) and -230Y (rs751032) respectively. To study the effect of these variations on AIRE promoter activity we generated a Flp-In host cell line which was stably transfected with a single copy of the reporter vector. Relative promoter activity was estimated by comparing the luciferase specific activity for lysates of the different reporter AIRE promoter-reporter gene constructs including AIRE-655G AIRE-230C, AIRE-655G AIRE-230T and AIRE-655A AIRE-230C. The analysis showed that the commonest haplotype AIRE-655G AIRE-230C has the highest luciferase specific activity (p<0.001). Whereas AIRE-655G AIRE-230T has a luciferase specific activity value that approaches null. Both AIRE promoter polymorphic sites have one allele that forms a CpG methylation site which we determined can be methylated in methylation assays using the M.SssI CpG methyltransferase. Conclusion AIRE-230Y is in a conserved region of the promoter and is adjacent to a predicted WT1 transcription factor binding site, suggesting that AIRE-230Y affects AIRE expression by influencing the binding of biochemical factors to this region. Our findings show that AIRE-655GAIRE-230T haplotype could dramatically alter AIRE transcription and so have an effect on the process of negative selection and affect susceptibility to autoimmune conditions.

    The application of field ionization mass spectrometry (FIMS) to the detection of air pollutants was investigated. Current methods are reviewed for measuring contaminants of fixed gases, sulfur compounds, nitrogen oxides, hydrocarbons, and particulates. Two enriching devices: the dimethyl silicone rubber membrane separator, and the selective adsorber of polyethylene foam were studied along with FIMS. It is concluded that the membrane enricher system is not a suitable method for removing air pollutants. However, the FIMS shows promise as a useable system for air pollution detection.

  6. DNA repair by thiols in air shows two radicals make a double-strand break

    Using agarose gel electrophoresis, we have measured the yields of DNA single- and double-strand breaks (SSBs and DSBs) for plasmid DNA {gamma}-irradiated in aerobic aqueous solution. The presence during irradiation of either of the thiols cysteamine or N-(2-thioethyl)-1,3-diaminopropane (WR-1065) resulted in a concentration-dependent decrease in the yield of SSBs and a much greater decrease in the yield of DSBs. This large differential protective effect was not produced by thioethers or an alcohol of structural similarity to the two thiols, suggesting that repair of DSB radical precursors by thiols is more efficient than for SSB precursors. These observations suggest the existence of a diradical intermediate in the formation of DSBs. The results argue against a major contribution by a single radical mechanism involving interstrand radical transfer via hydrogen abstraction by a peroxyl intermediate, since the half-life of this radical transfer reaction appears to be significantly greater than the lifetime of the intermediate. 35 refs., 7 figs.
