This dataset contains unified Bathymetric Plan Curvature GeoTiffs with 4x4 meter cell resolution describing the topography of 15 areas along the shelf edge off the South Atlantic Bight where NOAA South East Fisheries Independent Survey (SEFIS) are conducting research on Red Snapper (lutjanus campechanus). The multibeam data covers a total of 232 sq km and was collected in 2010 by the NOAA Ship Nancy Foster with a hull-mounted Kongsberg Simrad EM 1002 multibeam echo sounder (95 kHz). It was processed by NOAA's NOS/NCCOS/CCMA Biogeography Branch using CARIS HIPS 7.1 software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides and zoning from NOAA COOPS. The processed CARIS data was used to generate a CARIS BASE surface using CUBE. The CARIS export option "BASE Surface to ASCII" was then used to create a GeoTiff of the priority areas in ArcGIS 10. Curvature was derived from this surface using the plan curvature function in ArcGIS 3D Analyst.

This accession contains one month of geodetic data records (GDRs) from the GEOSAT Exact Repeat Mission (ERM) for the time period of April 01, 1988 to May 04, 1988. 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 early October 1986 to begin the Exact Repeat Mission (ERM) which lasted from November 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.

Meteorological, oceanographic, wave spectra, and other data were collected from FIXED PLATFORMS in the North Atlantic and other locations. Data were collected by the National Data Buoy Center (NDBC) in support of the Tropical Ocean Global Atmosphere (TOGA) project from 01 April 1988 to 29 April 1988. Data were processed by NODC to the standard NODC F291-Meteorology, Oceanography, and Wave Spectra from Buoys format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f291.html. Links to digital data are not available at this time. An analog file is available from NODC user services. The F291 format is used to report meteorological, oceanographic, and wave spectra data from NDBC moored buoys and fixed land stations. The format contains thirteen data record types to: 1) Identify the buoy position and other descriptive information; 2) report the meteorological measurements; 3) report wave energy spectra and wave direction; 4) report subsurface physical, biological and chemical oceanographic measurements; and 5) report detailed information on continuously measured wind speed and direction. Each record is 120 characters in length, sorted by station and record type. Record type is omitted where data defined in that type and not measured. The first nine columns for all records are to be used for file type (columns 1-3) and file identifier (columns 4-9). The file identifier, assigned by the originator, is a unique originator id for each data submission. After submission, the NODC reassigns to this field a unique and NODC identifier for internal use.

Fish benthic trawls were completed by the Southern California Coastal Water Research Project (SCCWRP). Data from 425 fisheries independent trawls ranging from 2-215 meters depth were collected in 1994 and 1998 during the months of June-August. Fish that were not present in at least 5% of the trawls were removed from this analysis. The data set contained information for 150 fish species, but removal of rare species resulted in 48 species. Site groups were calculated using the Bray-Curtis dissimilarity coefficient with average means clustering (Romesburg, 1991). Gear included a 7.6-m head-rope semi balloon otter trawl with 1.25 cm codend mesh trawled for 5-10 minutes at each station. For more information on trawl methods, see Allen et al. (1997), and Allen et al. (2003).

Line point intercept (LPI) surveys and benthic composition assessments were conducted during Rapid Ecological Assessments (REA) as part of the Pacific Reef Assessment and Monitoring Program (RAMP) cruise HA1101 in Marianas from 20110407 to 20110509. Surveys are conducted by the Coral Reef Ecosystem Division (CRED) of the NOAA Pacific Islands Fisheries Science Center (PIFSC) at biennial intervals to support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems. During the cruise, 9 REA sites were surveyed at Maug in Marianas. Benthic biologists from NOAA's Coral Reef Ecosystem Division conducted Line Point Intercept surveys to quantitatively document the benthic cover at pre-determined long-term monitoring REA sites. Two linear 25 m transects were surveyed with a 5 m inter-transect region between the end of Transect 1 and the start of Transect 2. The LPI diver determines the benthic composition at 20 cm intervals for a total of 125 data points per transect. All living benthic elements (e.g., coral, algae, and other invertebrates) were identified to the lowest taxonomic level possible, often substituting functional group categories for turf algae and crustose coralline algae when identification in the field was extremely difficult. In cases where the substrate is bare or covered with turf algae, the substrate composition is also noted as either sand, rock, rubble, carbonate pavement, or dead coral. The data allows for the assessment and monitoring of species composition and abundance and provide the basis for computing quantitative estimates of percent cover at higher taxonomic levels like functional group (live coral, macroalgae, turf algae) or on a finer taxonomic resolution such as genus level.

Habitat maps of the main Hawaiian Islands were created by visual interpretation of aerial photos and hyperspectral imagery using the Habitat Digitizer extension. Aerial photographs are valuable tools for natural resource managers and researchers since they provide an excellent record of the location and extent of habitats. However, spatial distortions in aerial photographs due to such factors as camera angle, lens characteristics, and relief displacement must be accounted for during analysis to prevent incorrect measurements of area, distance, and other spatial parameters. These distortions of scale within an image can be removed through orthorectification. During orthorectification, digital scans of aerial photos are subjected to algorithms that eliminate each source of spatial distortion. The result is a georeferenced digital mosaic of several photographs with uniform scale throughout the mosaic. Features near land are generally georeferenced with greater accuracy while the accuracy of features away from land is generally not as good. Where no land is in the original photographic frame only kinematic GPS locations and image tie points were used to georeference the images. After an orthorectified mosaic is created, photointerpreters can accurately and reliably delineate boundaries of features in the imagery as they appear on the computer monitor using a software interface such as the Habitat Digitizer.
