This dataset consists of full-disk images of the sun in Calcium (Ca) II K wavelength (393.4 nm). Ca II K imagery reveal magnetic structures of the sun from about 500 to 2000 km above the photosphere that are not evident in white light images. The chromosphere is an extremely dynamic layer of the sun consisting of a mixture of hot ionized plasma and cool gas. The presence of calcium ions in the chromospheric (along with other ions such as helium and hydrogen) lead to the absorption of radiant emission from the sun. The Ca II K absorption lines are extremely sensitive to local magnetic fields wherein the presence of stronger magnetic fields results in less absorption (brighter features) than weaker fields (more absorption = darker features). Unique features of the chromosphere evident in Ca II K are plage, pores, supergranulation cells and the chromospheric network. Also observed in Ca II K are solar features typically discussed in the context of the photosphere, including sunspots and faculae. Sunspots in photospheric observations appear as dark regions due to the cooler temperatures (~3000 oK) of the overlying gas compared to the surrounding solar surface (~5500 oK). Although sunspots are regions of intense solar magnetic activity (i.e. less absorption), the lack of radiant emissions from the underlying photosphere results in chromospheric sunspot regions that remain darker than the surrounding sun. Faculae, on the other hand, are brighter regions in chromospheric observations which result from the concentration of magnetic field lines between solar granules (solar convection cells). Closely associated with faculae are bright areas of chromospheric plage, also referred to as floccule, within solar active regions that are associated with sunspot formation. Solar pores are actually small sunspots that have not yet formed (and may never form) into the standard picture of a dark central umbra surrounded by a somewhat brighter penumbra. Supergranulation cells are large regions of convective horizontal flows (larger than individual granules) wherein solar material and an embedded magnetic field flow radially outward from the center and downward at the outer boundaries causing the web-like appearance of the chromospheric network structure.

In response to NASA's need to develop advanced nanostructured thermolectric materials, UTRON is proposing an innovative high pressure powder consolidation manufacturing to fabricate near net shape and net shape thermolectric components with improved densification and properties than possible conventional powder metallurgical methods. Potential candidate materials such as Tellurides, TAGs and SiGe micro/nano composites will be developed at high compaction pressures (150 tsi) using select geometries/shapes and optimized disk samples will be characterized for geometrical, shrinkage, mechanical, microstructure/microchemistry and thermolectric properties. The proposed work has been planned in close subcontract/collaboration with Teledyne and Auburn University-Space Research Institute. Other advanced nanocomposite alloys and scaling up to fabricate complex geometries will be done in Phase II.

Current meter data were collected using moored current meter casts in the North Atlantic Ocean from September 8, 1978 to October 1, 1979. Data were submitted by Edgerton, Germeshausen and Grier, INC. as part of the Outer Continental Shelf - Georges Bank (OCS -Georges Bank) project. Data were processed by NODC to the NODC standard Current Meter Data (F015) format. Full current meter moorings descriptions are available at http://www.nodc.noaa.gov/General/NODC-Archive/f015.html. The F015 format is used for time series measurements of ocean currents. These data are obtained from current meter moorings and represent Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth, and meter characteristics are reported for each station. The data record comprises values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north and negative directions west and south. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Water temperature, pressure, and conductivity or salinity may also be reported. A text record is available for optional comments.

This project aims to develop food packaging technologies for extending shelf-live toward maintaining healthy diet and psychological well being of the space crew. The underlying technology builds on sol-gel core competency of the company. InnoSense LLC (ISL) will collaborate with the Food Technology Department at Ohio State University (OSU) for independent testing of the Flexible ORMOSIL Nanocomposite (Flexorn<SUP>TM</SUP>) barrier materials. Through an iterative process of coating and testing, the Phase I project would demonstrate: (a) that the Flexorn barrier can be deposited onto polymeric substrates and can be adhesively bonded to a polypropylene layer for food packaging applications; (b) achievement of water vapor transmission rate (WVTR) < than 1 g/m2-day and oxygen transmission rate (OTR) < than 1 cc/m2-day for the flexible thin-film barrier. The focus of Phase II will be optimization of the barrier architecture, and the evaluation of prototype flexible pouches for their mechanical and barrier properties after retorting, a process typically used to package reheatable foods in flexible packaging applications. Prominent members of the Center for Advanced Processing and Packaging Studies (CAPPS) at OSU (e.g., Kraft Foods) have expressed strong interest in applying this NASA-funded technology to expand their market shares.

This accession contains one month of sensor data records (SDRs) from the GEOSAT Geodetic Mission (GM) for the time period of June 01, 1985 to June 30, 1985. Parameters include: time, orbit, latitude/longitude, and sea surface height. Corrections to the data include: sea level, wind and wave data, tides, dry and wet troposphere, ionosphere, height bias, altimeter crossover differences, altimeter sea surface measurement, and spacecraft orientation. These data were submitted by the U.S. Navy via National Oceanic Service. The US Navy Geosat (Geodetic Satellite) radar altimeter mission lasted for nearly 5 years (March 1985 to January 1990) and collected approximately 750 million measurements of sea level, wave height, and wind speed over the global oceans. During the Geodetic Mission (March 1985 to September 1986), the satellite did not repeat its ground track for the duration of the mission. The orbit of the satellite was changed in October 1986 to begin the Exact Repeat Mission (ERM) which lasted from November 8, 1986 until the satellite quit functioning in January 1990. During the ERM, the satellite repeated its ground track every 17 days. Data were initially processed by the Johns Hopkins University Applied Physics Laboratory in Laurel, MD in coordination with the NOAA/NOS Satellite Altimeter Group. Data products were transferred to the NOAA National Oceanographic Data Center (NODC) for distribution. Data products are archived at the NODC.

Environmental Sensitivity Index (ESI) maps are an integral component in oil-spill contingency planning and assessment. They serve as a source of information in the event of an oil spill incident. ESI maps contain three types of information: shoreline habitats (classified according to their sensitivity to oiling), sensitive biological resources, and human-use resources. Most often, this information is plotted on 7.5 minute USGS quadrangles, although in the Alaska ESI maps, USGS topographic maps at scales of 1:63,360 and 1:250,000 are used, and in other ESI maps, NOAA charts have been used as the base map. Collections of these maps, grouped by state or a logical geographic area, are published as ESI atlases. Digital data have been published for most of the U.S. shoreline, including Alaska, Hawaii, and Puerto Rico.

Description

This study examined temporal and spatial variability in shallow, soft bottom macrofauna communities in Mamala Bay, Oahu, Hawaii. Both short term (weekly) and long term (monthly) temporal changes were examined. Specifically, there were three objectives of this study. The first objective was to determine if temporal variability (lunar periodicity and seasonality) exists in community structure and biomass of Hawaiian soft bottom benthos. The second objective was to examine the temporal nature of the benthic response to freshwater runoff events. The third objective was to examine the spatial nature of the benthic infauna response to freshwater runoff. Temporal variability, both on short-term (within a month), and long-term (between months) time scales, was found to exist in the shallow water (10m) macrofauna communities of Oahu's south shore. The timing and magnitude of the variation was dependent upon the particular station examined. There was evidence for the existence of seasonality and lunar periodicity in certain taxa. Examination of the results of the rain event sampling combined with the results of spatial comparisons of stations along a transect leading away from Ala Wai Canal suggests that runoff from the Ala Wai is not important with respect to density of Total Macrofauna and Total Macrofauna biomass. K-dominance curves, combined with the results of Abundance Biomass Curves do not show a pattern indicating that stations located near the mouth of the Ala Wai Canal are negatively impacted by proximity to runoff. However, the results of the abundance biomass curves were not conclusive and further work needs to be done to determine if this technique would be useful in Hawaiian benthic communities to detect human-induced and natural perturbations.
