Description

The Population - Bridged-Race July 1st Estimates online databases report bridged-race population estimates of the July 1st resident population of the United States, based on Census 2000 counts, for use in calculating vital rates. These estimates result from "bridging" the 31 race categories used in Census 2000, as specified in the 1997 Office of Management and Budget (OMB) standards for the collection of data on race and ethnicity, to the four race categories specified under the 1977 standards (Asian or Pacific Islander, Black or African American, American Indian or Alaska Native, White). Many data systems, such as vital statistics, are continuing to use the 1977 OMB standards during the transition to full implementation of the 1997 OMB standards. Postcensal estimates are available for year 2000 - 2009; intercensal estimates are available for the years 1990-1999. Obtain population counts by Year, State, County, Race (4-categories), Ethnicity, Sex and Age (1-year or 5-year groups). The data are released by the National Center for Health Statistics.

NODC Accession 0112634 includes site samples and biological data collected aboard the LAURENCE M. GOULD during cruises LMG0106 and LMG0205 in the South Atlantic Ocean and South Pacific Ocean from 2001-07-28 to 2002-09-05. These data include SPECIES IDENTIFICATION - ORGANISM LENGTH, growth rate and SPECIES IDENTIFICATION - LIFE STAGE. The instruments used to collect these data include net - plankton net. These data were collected by Langdon Quetin and Robin Ross of University of California-Santa Barbara as part of Southern Ocean GLOBEC. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NODC on 2013-07-25. The following is the text of the abstract provided by BCO-DMO: The goal of the larval krill studies was to investigate the physiology and ecology of krill larvae associated with the pack ice and the microbial community on which they feed. During LMG0106 we occupied two 4-5 day ice stations (Robert and Billy) and sampled several other ice floes opportunistically. We conducted 10 instantaneous growth rate experiments, and 4 whole body clearance time experiments to determine gut passage time (decline in pigment content over time). We also sampled larvae at two additional sites for initial body pigment content (whole body fluorescence), and at 4 sites for condition factor. The under-ice algal community was sampled at one site. Length and stage frequency determinations were also determined. We occupied three time-series stations of approximately 1 week each, and in addition opportunistically sampled at times when other activities had priority. Our primary goal during the cruise was to occupy three ice camps or process stations with the intent of thoroughly studying the under-ice environment by SCUBA in conjunction with other projects working topside.

Description

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the Universal Transverse Mercator Zone 18 North. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000. Coastal study data as defined in FEMA Gudelines and Specifications, Appendix D: Guidance for Coastal Flooding Analyses and Mapping, submitted as a result of a coastal study. Appendix D notes that a variety of analytical methodologies may be used to establish Base (1-percent-annual-chance) Flood Elevations (BFEs) and floodplains throughout coastal areas of the United States. Appendix D itemizes references for the methodologies currently in use by FEMA for specific coastal flood hazards, provides general guidance for documentation of a coastal flood hazard analysis, specifies flood hazard analysis procedures for the Great Lakes coasts, and outlines intermediate data submissions for coastal flood hazard analyses with new storm surge modeling and revised stillwater flood level (SWFL).

<p>The Space Food Systems Laboratory's (SFSL) current Bulk Overwrap Bag (BOB) package, while simple and effective, leaves room for improvement. Currently, BOBs are sized to fit in Cargo Transfer Bags (CTB). On orbit, however, the pantry setup utilizes several Collapsible US Food Containers (CUFC). In addition, the entirety of the menu must be overwrapped with an aluminum laminate package in order to meet the oxygen and water vapor permeability requirements of an 18 month shelf life requirement. The development of a Phase II BOB could alleviate several or all of these issues in a cost, mass, and volume sensitive manner by changing the size and shape of the BOB as well as potentially finding an alternative material with sufficient barrier properties to eliminate the secondary overwraps.</p>

Description

Traditional structural health monitoring (SHM) methods have been limited due to the implied infrastructure, including wires for power and communication from each sensor to data acquisition units. Presently, Metis Design Corporation (MDC) has demonstrated the patented technique of point-of-measurement datalogging. During the proposed research, MDC will further exploit this SHM architecture to satisfy NASA mission specifications. This work focuses on a Boeing Proprietary technology that allows cable-free transfer of electrical signals. To date, this technology has been demonstrated to successfully power and transfer data from analog sensor arrays. During Phase I, MDC will work with Boeing to demonstrate this technology for a digital sensor bus. The first task will aim to modify the existing sensor hardware to be physically compatible with such a bus. The second task will investigate attachment mechanisms that will provide the necessary electrical connections while not sacrificing strength or structural coupling for wave propagation. The third task will seek to design an impedance matching circuit for the sensor-bus to support multiple sensors for both power and data on the same CAN-style bus. The final task will piece each of these components together to demonstrate damage detection and localization on a composite plate supplied by Boeing.

Description

This part of DS 781 presents data for the bathymetry and shaded-relief maps of the Offshore Half Moon Bay, California (raster data file is included in "Bathymetry_OffshoreHalfMoonBay.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreHalfMoonBay/data_catalog_OffshoreHalfMoonBay.html. The bathymetry and shaded-relief maps of Offshore Half Moon Bay, California, were generated from bathymetry data collected by Fugro Pelagos, and by California State University, Monterey Bay (CSUMB). Mapping was completed in 2006 and 2007, using a combination of 400-kHz Reson 7125 and 244-kHz Reson 8101 multibeam echosounders. These mapping missions combined to collect bathymetry from about the 10-m isobath to beyond the 3-nautical-mile limit of California's State Waters. NOTE: the horizontal datum of the bathymtry data (NAD83) differs from the horizontal datum of other layers in this SIM (WGS84). Some bathymetry grids within this map were projected horizontally from WGS84 to NAD83 using ESRI tools to be more consistent with the vertical reference of the North American Vertical Datum of 1988 (NAVD88). These data are not intended for navigational purposes.

Description

Optical Physics Company (OPC) has developed new silicon carbide (SiC) foam-based optics with hybrid skins that are composite, athermal and lightweight (FOCAL) that provide an enabling capability for performing NASA space missions that will require 2 to 3 meter class cryogenic mirrors for infrared telescopes. The key development in the Phase I program was the replacement of OPC monolithic SiC skins with SiC fiber reinforced/SiC CVD hybrid skins on 1.5" coupons, 4" flat and then 12" powered optics. This innovation avoids scale-up problems that include the inherent stress in the monolithic skins which can result in skin cracking during the substrate manufacturing and finishing processes, the non-uniformity of the .040"-.050" thick monolithic skins that typically require .010"-.015" of material removal before a continuous surface can be achieved for optical finishing, the long schedule of manufacturing the mirror substrate, and the large $2M/m2 cost to produce the polished mirror. The hybrid skin technology provides increased skin strength and toughness to enable the foam based technology to produce meter class mirrors without skin cracking. The manufacturing time and CVD chamber cost are reduced because premanufactured SiC fibers are used to provide the bulk of the skin mass rather than laying down a monolithic skin atom by atom via CVD. The net effect is to produce a SiC FOCAL mirror substrate that is stronger, tougher, scalable to meter class, and potentially better than 50% faster and cheaper to manufacture. OPC proposes to demonstrate that the hybrid skin technology developed in Phase I can be successfully applied to manufacture a 22" diameter F/2 spherical SiC FOCAL hybrid skin substrate and then polish it into a precision mirror on a Phase II program.

Description

Numerous low impact development (LID; green infrastructure) technologies are being developed and implemented to reduce the impacts of toxic stormwater runoff on aquatic habitats. Examples include permeable pavements, rain gardens, green roofs, soil mesocosms, and other approaches. NOAA and other federal agencies need to know which of these strategies are effective, scalable, and most appropriate for myriad decisionmaking contexts (e.g., ESA consultations involving federal highway projects in the western US). To this end, the Ecotoxicology program is investigating LID effectiveness in collaboration with the U.S. Fish and Wildlife Service (USFWS) and Washington State University (WSU), at WSU's new multi-million dollar stormwater research facility in Puyallup. Ongoing project work is funded by the EPA, USFWS, and the NOAA Coastal Storms Progam. In addition to the Northwest Regional Office (NWR), key end-users for the science include other federal agencies, state agencies (e.g., the Puget Sound Partnership, Ecology), municipalities (e.g., the City of Seattle), tribal organizations, science educators, and the public. Measurements of water toxicity in fish and invertebrates.

Description

Gamma-ray and neutron spectroscopy are well established techniques for determining the chemical composition of planetary surfaces, and small cosmic bodies such as asteroids and comets; however, new technologies with the potential to significantly improve the performance of planetary nuclear spectroscopy are emerging. We propose to develop new gamma-ray and neutron detectors based on wide-band-gap (WBG) solid-state photomultiplier (SSPM) photodetectors coupled to emerging scintillation materials such as Cs2YLiCl6:Ce (CLYC), and CeBr3 for gamma and neutron spectroscopic studies of planet surfaces and small cosmic bodies. The proposed SSPM photodetector for scintillation readout is based on AlGaAs, a WBG compound semiconductor with aluminum concentration of 60% to 90%. The ~2-eV band-gap energy of this material is engineered to match the emission spectrum of both CLYC and CeBr3. The high band-gap of AlGaAs also provides much lower dark noise and better radiation tolerance than Si-based detectors. Compared to conventional PMTs, the compact size, low voltage operation, and lighter weight of AlGaAs SSPM is ideal for spaced-based instruments. The advantages of AlGaAs SSPMs and the excellent detection properties of CLYC and CeBr3 scintillation materials make them a perfect match in the development of new gamma and neutron spectrometers for planetary science.

Description

The National Geodetic Survey (NGS), an office of NOAA's National Ocean Service, manages a network of Continuously Operating Reference Stations (CORS) that provide Global Navigation Satellite System (GNSS) data consisting of carrier phase and code range measurements in support of three dimensional positioning, meteorology, space weather, and geophysical applications throughout the United States, its territories, and a few foreign countries. Surveyors, GIS users, engineers, scientists, and the public at large that collect GPS or GNSS data can use CORS data to improve the precision of their positions. CORS enhanced post-processed coordinates approach a few centimeters relative to the National Spatial Reference System, both horizontally and vertically. The CORS network is a multi-purpose cooperative endeavor involving government, academic, and private organizations. The sites are independently owned and operated. Each agency shares their data with NGS, and NGS in turn analyzes and distributes the data free of charge. As of October 2014, the CORS network contains over 2030 stations, contributed by over 200 different organizations, and the network continues to expand.

Description

Digital orthoimages combine the image characteristics of a digital image with the geometric qualities of a map. The primary dynamic digital orthophoto quarter quadrangle (DigitalGlobe DOQQ) is a 60 centimeter ground resolution, quarter-quadrangle (3.75 minutes of latitude by 3.75 minutes of longitude) image cast to the customer specified projection and datum defined in the Spatial Reference Information section of this metadata document. The geographic extent of the DG DOQQ is equivalent to a quarter-quadrangle plus the overedge of 300 meters beyond the extremes of the primary corner points. The overedge is included to facilitate tonal matching for mosaicking and ensure full coverage if the imagery is reprojected. The normal orientation of data is by lines (rows) and samples (columns). Each line contains a series of pixels ordered from west to east with the order of the lines from north to south. The digital orthoimage is formatted as a GeoTIFF image file with a separate FGDC compliant metadata file.

Description

This proposal describes the development of passive wireless surface acoustic wave (SAW) RFID sensor-tags with enhanced range for remote monitoring of large groups of conventional sensors. Passive wireless sensing tags using SAW technology have been demonstrated by Robert Brocato at Sandia National Labs and others. These sensor-tags consist of a SAW device with an antenna attached to one port and sensor(s) and reference impedance(s) connected to the other ports. RF signals are reflected off of the surface wave device, and their reflection characteristics are modified by changes in the impedance of the attached sensor(s). This proposal describes development of novel passive wireless SAW sensor tags that combine radio frequency identification (RFID) coding with dispersive and low-loss SAW transducers and reflectors. The proposed devices utilize RFID reflective delay line coding techniques to produce devices capable of data densities over 32 bits, enabling production of large codesets. Variations in the reflected RFID code are used to identify the device and to provide a measure of the attached sensor(s), along with any internal sensing function(s). The use of dispersive low-loss transducers and reflectors provides increased processing gain and over 10 times the range of conventional SAW RFID tags. The proposed sensor devices also operate in a manner that is inherently immune to RF backscatter signals, further enhancing S/N. Successful completion of the proposed Phase I activities will establish the technical feasibility of these sensor-tags, will evaluate their performance in the laboratory when used with at least two external sensor devices, and will provide performance projections for use with other sensors. At the end of Phase I, devices will be at TRL 4. Phase II will result in development of multiple uniquely identifiable passive sensor-tags and interrogation systems operable to wirelessly monitor sensors of interest to specific NASA programs (TRL6).

Description

The Geostationary Operational Environmental Satellites (GOES) operated by the United States National Oceanographic and Atmospheric Administration (NOAA) support weather forecasting, severe storm tracking, meteorology and oceanography research. Generally there are several GOES satellites in geosynchronous orbit at any one time viewing different earth locations including the GOES-12 launched 23 July 2001. The radiometer aboard the satellite, The GOES I-M Imager, is a five channel (one visible, four infrared) imaging radiometer designed to sense radiant and solar reflected energy from sampled areas of the earth. The multi-element spectral channels simultaneously sweep east-west and west-east along a north-to-south path by means of a two-axis mirror scan system retuning telemetry in 10-bit precision. For this Group for High Resolution Sea Surface Temperature (GHRSST) dataset, skin sea surface temperature (SST) measurements are calculated from the far IR channels of GOES-12 at full resolution on a half hourly basis. In native satellite projection, vertically adjacent pixels are averaged and read out at every pixel. L2P datasets including Single Sensor Error Statistics (SSES) are then derived following the GHRSST Data Processing Specification (GDS) version 1.5. The full disk image is subsetted into granules representing distinct northern and southern regions.
