Description

XBT data were collected from the NOAA Ship Oregon in support of the Integrated Global Ocean Services System (IGOSS) project. Data were collected by the National Marine Fisheries Service (NMFS) from 24 June 1975 to 17 July 1975. 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 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.

Fish survey, fishing duration, and other data were collected from the NOAA Ship MILLER FREEMAN from 02 September 1976 to 09 October 1976. Data were submitted by the National Marine Fisheries Service (NMFS) as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F123 Fish/Shellfish Surveys format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f123.html. An analog file for this accession is available from NODC user services. The F123 format is used for data from field sampling of marine fish and shellfish. The data derive from analysis of midwater or bottom tow catches and provide information on population density and distribution. Cruise information, position, date, time, gear type, fishing distance and duration, and number of hauls are reported for each survey. Environmental data may include meteorological conditions, surface and bottom temperature and salinity, and current direction and speed. Bottom trawl or other gear dimensions and characteristics are also reported. Catch statistics (e.g., weight, volume, number of fish per unit volume) may be reported for both total haul and for individual species. Biological characteristics of selected specimens, predator/ prey information (from stomach contents analysis), and growth data may also be included. A text record is available for comment.

Towed-diver surveys (aka. Towboard surveys) are conducted by the Coral Reef Ecosystem Division (CRED) of the NOAA Pacific Islands Fisheries Science Center (PIFSC) as part of biennial Pacific Reef Assessment and Monitoring Program (RAMP) Cruises. These cruises support NOAA Coral Reef Conservation Program (CRCP) long-term goals for sustainable management and conservation of coral reef ecosystems. 26 towboard surveys (56.3929 km in length), were conducted at French Frigate Shoals in the NW Hawaiian Islands from 12 September - 12 October 2008 as part of RAMP Cruise HI0809. Towboard surveys are a good method for obtaining a general description of large reef areas, assessing the status of low-density populations of large-bodied reef fish, large-scale disturbances (e.g., bleaching), general distribution and abundance patterns of macro-invertebrates (e.g., COT, giant clams), and for assessing trends in these populations and metrics. A pair of scuba divers (1 fish and 1 benthic diver) are towed 60 m behind a small survey launch at a speed of 1-2 knots and a depth of approximately 15m. Each survey is 50 min long, covers about 2 km of habitat, and is divided into ten 5-minute survey segments. The fish diver records, to the lowest possible taxon, all large-bodied reef fishes (>50cmTL) seen within 5m either side and 10m in front of the towboard. Length of each individual is estimated to the nearest cm. The fish towboard is also outfitted with a forward-facing digital video camera to record the survey swath. The benthic diver records percent cover of coral and macroalgae, estimates benthic habitat type and complexity, and censuses a suite of benthic macroinvertebrates including Crown of Thorns sea stars and sea urchins. The benthic towboard is equipped with a downward-facing digital still camera which images the benthos at 15 second intervals. These images are analyzed for percent cover of coral, algae, and other benthic components. Both towboards are equipped with SEABIRD SBE-39 temperature/depth sensors set to record at 5 second intervals. Latitude and longitude of each survey track is recorded at 15 second intervals using a Global Positioning System (GPS) receiver onboard the tow boat. A layback algorithm is applied to more accurately map the position of the divers with respect to the reef environment. This algorithm calculates the position of the divers based on the position of the tow boat taking into account the length of the tow rope, the depth of the divers, and the curvature of the survey track. This metadata applies to the fish biomass observations.

Benthic habitat polygon coverages are being created for the Olympic Coast National Marine Sanctuary (OCNMS). OCNMS has collected side scan sonar, multibeam backscatter, multibeam bathymetry, bottom grab and video data to produce polygon coverages describing seafloor substrate for various areas within the sanctuary. For this particular area, a maximum likelihood classification rule was used to segment side scan sonar imagery using local fourier histogram texture features calculated from grey scale pixel intensity values. The habitat polygons have attributes for megahabitat, bottom induration, mesohabitat, macrohabitat, polygon area and perimeter.

To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, from 25 May - 09 June 2007, line point intercept (LPI) surveys of benthic parameter assessments were conducted, as a part of Rapid Ecological Assessments (REA), during the Pacific Reef Assessment and Monitoring Program (RAMP) Cruise HI0703 in the Marianas Archipelago at biennial intervals by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC). During the cruise, 3 REA sites were surveyed at Sarigan Island in the Marianas Archipelago. At the specific REA sites, coral biologists along with algal biologists, marine invertebrate zoologist, and fish biologists entered the water and conducted a fine-scale (~300 m2) and high degree of taxonomic resolution REA survey to assess and monitor species composition, abundance, percent cover, size distribution, diversity, and general health of fish, corals, macro-invertebrates, and algae in shallow-water (< 35 m) habitats. As a part of REA surveys, the line point intercept surveys were used to quantitatively assess average percent live coral cover and other benthic substrates at REA sites. The surveys were conducted along two consecutively-placed 25m transect lines by a coral biologist. All benthic elements falling directly underneath the transect line at 20-cm to 50-cm intervals were recorded as one of nine benthic categories: live coral, dead coral, carbonate pavement, encrusting coralline algae, macroalgae, coral rubble, sand, rock, and other benthic sessile invertebrates. All living benthic elements (e.g., coral, algae, and other invertebrates) were identified to the lowest taxonomic level possible. These data provide the basis for computing quantitative estimates of percent live coral cover, as well as percent cover of the different benthic constituents.
