This image represents a 8 meter resolution bathymetry of a reef shelf/bank and the steep canyons and slopes of the NE Reserve, offshore of Fajardo, Puerto Rico. The M-I907-NF-13 survey was split into two sites: W00247 in the west and W00246 in the east. NOAA's NOS/NCCOS/CCMA Biogeography Team, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in the Northeast Grand Reserve from 3/05/2013 to3/29/2013. Data was acquired with a hull-mounted Kongsburg Em 1002 echosounder (95 kHz) and 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 from NOAA COOPS. Data is in UTM zone 20 north, datum NAD83. The backscatter component of the bathymetry data were geometrically and radiometrically corrected using Hypack 2012 acquisition software. 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.

Temperature profile data were collected using bathythermograph (BT/XBT) casts from YAMASHIN MARU in the Pacific Ocean from June 7, 1977 to June 8, 1977. Data were submitted by Scripps Institution of Oceanography as part of the Thermal Structure Monitoring Program in the Pacific (TRANSPAC) project. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full BT descriptions are available at http://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 record was comprised of pairs of temperature-depth values. Unlike the MBT Data File, in which temperature values were recorded at uniform 5 m intervals, the XBT data files contained 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 either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m.

Current meter data were collected using moored current meter casts in the TOGA Area - Pacific (30 N to 30 S) from April 16, 1984 to October 1, 1985. Data were submitted by Pacific Marine Environmental Laboratory (PMEL) as part of the Equatorial Pacific Ocean Climate Studies (EPOCS) 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.

Meteorological, oceanographic, wave spectra, and other data were collected from FIXED PLATFORMS in the North Atlantic Ocean and other locations. Data were collected by the National Data Buoy Center (NDBC) from 01 December 1991 to 31 December 1991. 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.

NITROP - 85 was the major field of experiment of an N.S.F. funded program entitled "Microbial Nitrogen Transformations in the Oxygen Minimum Zone off Peru". this project focused on obtaining a better understanding of the microbially mediated changes in nitrogen pathways and the controls on these pathways in and at the boundaries of the oxygen deficient water masses (O2 < 0.05 ml/l) found off Peru. The somewhat "random walk" nature of our cruise track and the existence of multi-cast stations reflects this emphasis. Considerable effort was expended on finding the right conditions to test various aspects of our hypotheses, and once a favorable site was located, many casts were necessary to obtain the large volume samples needed for some of our experiments. Since particle maxima appear to be well correlated with the nitrite maxima that are imbedded in the core of the oxygen deficient water masses, we also determined optical characteristics of the water at our sampling sites. Primary productivity and chlorophyll observations were also made during NITROP - 85.

Temperature profile data were collected from MBT casts from a a World-Wide distribution. Data were collected from the ALASKA and other platforms from 02 February 1943 to 10 October 1964. 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. This 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.

To support NOAA Coral Reef Conservation Program (CRCP) long-term goals for sustainable management and conservation of coral reef ecosystems, towed-diver surveys (aka. towboard surveys) were 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. 18 towboard surveys (38.9520 km in length), were conducted at Ofu And Olosega Islands during the American Samoa RAMP Cruise OES0402 from 3 - 26 February 2004. 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 benthic characterization observations.
