This dataset contains a comma-delimited ASCII XYZ text file with easting, northing, and depth in meters values for the bathymetry of a selected portion of seafloor around Tourmaline Bank, Puerto Rico. XYZ values are derived from a 6 m resolution gridding process. Bathymetry data were collected in 2008. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in Puerto Rico from 2/25/08 to 3/8/08. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) in 2008. It was processed by a NOAA contractor using CARIS HIPS 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. Data is in UTM zone 19 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. An ASCII XYZ file was exported from the BASE surface and imported to ESRI ArcMap 9.2 using the Convert XYZ to Raster tool developed by CCMA for this purpose. The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards.

Marine animal sighting and census data were collected from the NOAA Ship SURVEYOR from 11 May 1982 to 19 March 1983. Data were collected by the Envirosphere Co. as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F127 Marine Animal and Census format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f127.html. An analog file for this accession is available from NODC user services. The F127 format is used for data from field observations of marine animals. Data may be reported either for individual, random sightings or for sightings made as part of systematic ship or aircraft surveys along specified tracks. These data provide information on animal population densities and distributions, activities, migratory routes and breeding locales. Cruise or survey information, start and end positions, start and end times, and platform speed, direction, and altitude are reported for each observation or series of observations. Position, date and time are reported for each sighting location, along with a code indicating presence or absence of animals and, if present, their distance to the observer, shoreline, and ice edge and heading direction. For each sighting location, animal sighting data are reported by species for all observed species. Species identification, total number of individuals, and counts by age group (adults, subadults, juveniles, unknown) may be reported in summary for all animals sighted or by subgroups distinguished by sex, behavior, markings, or other characteristics. A text record is available for comments.

Current meter data were collected using moored current meter casts in the Coastal Waters of California from April 12, 1981 to April 1, 1983. Data were submitted by Woods Hole Oceanographic Institution (WHOI) as part of the Coastal Ocean Dynamics Experiment (CODE) 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.

A genetic analysis of chum salmon (Oncorhynchus keta) bycatch from the 2013 Bering Sea walleye pollock (Gadus chalcogrammus) trawl fishery was undertaken to determine the overall stock composition of the sample set. Samples were genotyped for 11 microsatellite markers and results were estimated using the current chum salmon microsatellite baseline. Since 2011, genetic samples from the chum salmon bycatch were collected systematically to reduce sample biases that may exist in collections from previous years. In 2013, one genetic sample was collected for every 30.3 chum salmon caught in the 99.8% of the midwater trawl fishery that was sampled. Evaluation of sampling based on time, location, and vessel indicated that the genetic samples were representative of the total bycatch. Based on the analysis of 3,880 chum salmon bycatch samples collected throughout the 2013 Bering Sea trawl fishery, the Northeast Asia stocks dominated the sample set (45%); moderate contributions came from Southeast Asia (15%), Eastern Gulf of Alaska (GOA)/Pacific Northwest (PNW) (15%), and Western Alaska (18%) stocks, and smaller contributions came from Upper/Middle Yukon River (6%) and Southwest Alaska (1%) stocks. The regional stock estimates for the 2013 chum salmon bycatch were similar to those for the 2012 bycatch, but differed significantly from estimates for other years, especially for the Asian and the Eastern GOA/PNW regions. There were significant spatial differences in stock distribution with the Southeast Asia contribution higher in the northwestern U.S. waters of the Bering Sea than in the southeastern Bering Sea, and the Eastern GOA/PNW contribution highest in the easternmost area sampled in the southeastern Bering Sea. Analysis of temporal strata revealed changes in stock composition during the course of the fall B season with increasing contribution of Northeast Asia stocks, decreasing contribution of Eastern GOA/PNW stocks, and variable contribution from Southeast Asia and Western Alaska.
