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 UTM projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12000.

Description
Zyvex in cooperation with Prairie View A&M (CARR) and Boeing will develop a space radiation shielding multi-functional material that will provide high energy radiation shielding required to protect astronauts on extended missions, strong enough to be used as an integral structural material and tough enough to survive micro-meteor impacts, provide EMI shielding, and enhanced thermal conductivity. The team will also develop an improved protocol for testing radiation shielding material. This effort will entail developing a composite material which uses proven radiation shielding material Polyethylene(PE), as its primary constituent in the form of very strong/tough Spectra fibers woven into a 3D fabric. In Phase 1 we demonstrated that, compared to bulk PE, this composite approach has significantly improved mechanical properties, excellent electrical conductivity, good Electro Magnetic Interference (EMI) shielding properties, and maintains excellent space radiation shielding properties of PE. We also demonstrated exposure to large doses of high energy actually improved the mechanical properties. In Phase II, the epoxy matrix used in Phase I will be considered along with Cyanate Esters, and Polyimides, As in Phase I, coating the PE fabric and reinforcing the matrix material will be ultra-high strength, highly conductive carbon nanotubes (CNTs). Zyvex's unique and commercially successful CNT processing technology will be adapted to maximize the transfer of the extraordinary mechanical, electrical, and thermal properties of CNTs to the composite structures. The work plan includes approaches to overcome CNT processing and delamination issues discovered in Phase I. CARR will carryout more extensive radiation testing with several ions at different energies. Boeing which has significant interest in developing long term space exploration will guide the development of the material to meet specifications for planned applications.

Summary
Description
Temperature profile and other data were collected using CTD, BT, and XBT casts from the NOAA Ship RESEARCHER and other platforms in the North/South Pacific Ocean and North/South Atlantic Ocean. Data were collected from 13 January 1973 to 14 March 1983. Data were collected by the Atlantic Oceanographic and Meteorological Laboratory in Miami, Florida and other institutes with support from the Equatorial Pacific Ocean Climate Studies (EPOCS) project. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format and High-Resolution STD/CTD Data (F022) format. Full format description is available from NODC at http://www.nodc.noaa.gov/General/NODC-datafmts.html The UBT file format is used for temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Standard XBTs can obtain profiles at depths of about 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Cruise information, position, date, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Unlike the MBT data file, in which temperature values are recorded at uniform 5m intervals, the XBT Data File contains temperature values at non-uniform depths. These depths are at a minimum number of points ("inflection points") required to record the temperature curve to an acceptable degree of accuracy. On output, however, the user may request temperature values either at inflection points or interpolated to uniform depth increments. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.

The "HIRDLS/Aura Level 3 Ozone (O3) Zonal Fourier Coefficients" version 7 data product (H3ZFCO3) contains the entire mission (~3 years) of HIRDLS data expressed as zonal Fourier coefficients in 1 degree latitude bands and 121 pressure levels. The coefficients are computed from the HIRDLS Level 2 profiles with a Kalman filter approach using both forward and backward passes in time. Expressed as the mean and up to 7 sine and cosine coefficients (4 waves for ascending and descending, 7 waves for combined), these coefficients may be used to compute values at any longitude. The data are provided on a pressure grid with 24 levels per decade, corresponding to about 1 km vertical resolution. The vertical range of the data is 422 to 0.1 hPa. The precision values are given by the root-mean square of the differences between the estimated fields and the input data. The data are stored in the version 5 Hierarchical Data Format for the Earth Observing System (HDF-EOS5), which is an extension of the HDF5 format. Each file contains a zonal object with data for the entire mission with separate data fields for ascending (daytime), descending (nighttime), and combined orbit node. The data arrays have 145 latitude steps (-64 to 80 degrees), 121 pressure steps, 15 Fourier coefficients (mean plus first 7 cosine and 7 sign waves), and 1151 daily time steps from January 22, 2005 through March 17, 2008. The coefficients are computed at a daily synoptic time of 12:00 UTC. That time is expressed in TAI-93 seconds (seconds since January 1, 1993) and the date is also stored in separate year, month and day fields. The ascending and descending datasets include LocalSolarTime and SolarZenithAngle values. Parameters contained in the data files include the following: Variable Name|Description|Units O3|Ozone (O3) Volume Mixing Ratio|mol/mol End of parameter information

Description
This project was a cooperative effort among the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment; the University of Hawaii; and Analytical Laboratories of Hawaii, LLC. The goal of the work was to develop coral reef mapping methods and compare benthic habitat maps generated by photointerpreting georeferenced color aerial photography, hyperspectral and IKONOS satellite imagery. Twenty-seven distinct benthic habitat types within eleven zones were mapped directly into a GIS system using visual interpretation of orthorectified aerial photographs and hyperspectral imagery. Benthic features were mapped that covered an area of 790 km^2. In all, 204 km^2 of unconsolidated sediment, 171 km^2 of submerged vegetation, and 415 km^2 of coral reef and colonized hardbottom were mapped. The Biogeography program developed an ArcIMS browser to allow users to view maps of the Island of Kauai and perform basis queries of the data over the internet.

Summary
Description
Bathythermograph data were collected from the CASCO within a 1-mile radius of Ocean Weather Station C (5245N 0350W) and in transit. Data were collected by the United States Coast Guard from 25 September 1962 to 18 October 1962. The platform was equipped and staffed to observe weather and sea conditions. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT file format is used for temperature-depth profile data obtained using the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.

Summary
Description
As the length of manned space missions increase, requirements to sustain those missions increase proportionately. Daily food supplies require food packaged and sent from earth, preparation mechanisms and waste treatment. The window for food preservation could be 3-5 years. This will require food packaging that provides excellent barriers to water vapor and oxygen, is durable at the processing conditions (retort sterilizing, microwave processing), and has low mass. Storage and disposal of used food packaging becomes a significant issue. Incineration is a reasonable waste treatment strategy, but is incompatible with materials used currently for high barrier packaging, like aluminum foil (which leaves ash). TDA Research, Inc. proposes to develop a multilayer nanocomposite film with superb resistance to permeation by water vapor and oxygen, for use as an extended shelf life food packaging material. We propose to prepare nanocomposites from commercially available packaging plastics and TDA's surface-modified nanoparticles. TDA's nanocomposite research has focused on the design of surface treatments to produce nanoparticles compatible with targeted host polymers. We can form well-dispersed nanocomposites with several packaging plastics and have seen improved barrier properties ? with nanoparticle contents less than 5%. TRL at the end of the Phase II contract will be at Level 5.

Output fields from the NOAA WAVEWATCH III® wave model monthly hindcasts for 2012-04 (NODC Accession 0098969)
Published By National Oceanic and Atmospheric Administration, Department of Commerce
Issued about 9 years ago
Summary
Description
The NOAA WAVEWATCH III® hindcast dataset comprises output fields from the monthly WAVEWATCH III® hindcast model runs conducted at the National Centers for Environmental Prediction. Each model run produces a collection of files containing gridded fields comprised of input and mean wave parameters such as the significant wave height, directions, frequencies etc. Once per month, a wave simulation is carried out using restart files from the previous month and forced by hindcast wind products for the entire month. The resulting output data are transferred to NODC on a monthly basis. NODC assembles the series of files into monthly accessions to facilitate archival retention and public access. The fields are encoded in the standard GRIdded Binary version 2 (GRIB2) file format. Wave spectral data summaries are included, as well as detailed spectra at selected locations, in tabular text format. Nine different sets of output fields, corresponding to nine different grids used in the numerical simulations, are included. These include a global grid, as well as regional and coastal grids covering much of the North Atlantic and North Pacific oceans.
