The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information. NOAA is responsible for archiving and distributing the source data as described in this metadata record.

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.

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.

XBT data were collected from the ATLANTIS II in support of the Integrated Global Ocean Services System (IGOSS) project. Data were collected by Woods Hole Oceanographic Institution (WHOI) from 12 October 1974 to 22 October 1974. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT). 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 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.

Belt transects along 2 consecutively-placed, 25m transect lines were surveyed as part of Rapid Ecological Assessments conducted at 4 sites at Baker, Phoenix Islands in the Pacific Remote Island Areas (PRIAs) during 24 January - 14 February 2008 in the NOAA Hi'ialakai (HI0801) Reef Assessment and Monitoring Program (RAMP) Cruise. Raw survey data included species presence and relative abundance, colony counts and size classes by genus, and determination of benthic cover using the line-intercept method. Depending on colony density, 1 m on each side of the transect lines was included in the belt (for a total of 25-50m2 per site).

Temperature profiles were collected from XBT casts from the JENNIE & JACKIE from 31 July 1978 to 02 August 1978. Data were collected by the National Marine Fisheries Service (NMFS) as part of the Marine Resources Monitoring, Assessment and Prediction (MARMAP) project. 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 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data records are comprised of pairs of temperature-depth values. The XBT data files contain temperature values at non-uniform depths. These depths were recorded at the minimum number of points (''''inflection points'''') required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of 450 m or 760 m. Special instruments permitted measurements to 1830 m.
