NODC accession 0104363 includes biological, chemical, optical, physical and underway data collected aboard the THOMAS G. THOMPSON during cruise TN260 in the North Pacific Ocean from 2010-12-26 to 2011-01-04. These data include Attenuation/Transmission, CONDUCTIVITY, CURRENT SPEED - EAST/WEST COMPONENT (U), CURRENT SPEED - NORTH/SOUTH COMPONENT (V), DEPTH - BOTTOM, DEPTH - OBSERVATION, DISSOLVED OXYGEN, FLUORESCENCE, HYDROSTATIC PRESSURE, SALINITY and WATER TEMPERATURE. The instruments used to collect these data include ADCP, CTD, GPS, echo sounder, fluorometer, oxygen meter and transmissometer. These data were collected by Richard Keil of University of Washington as part of Student Cruise. The Lamont-Doherty Earth Observatory (LDEO) submitted these data to NODC as part of the NSF sponsored Rolling Deck to Repository (R2R) program. The CTD data submitted by the originator represent the raw data suite. Processed versions of the data were generated by NODC. The ADCP data represent the raw and automated processed data set. Post processed quality assessed data are not available in this accession.

The Submarine Ring of Fire 2012 cruise will use the University of Bremen Quest 4000 remotely operated vehicle to locate, map and sample hydrothermal sites at seamounts and spreading centers in the Lau Basin. The sites were discovered by water column surveys, camera tows and prior dives with a remotely operated vehicle during cruises funded by NOAA, NSF and Nautilus Minerals Inc. in the past 8 years. They range in depth from ~750 to ~2600 m. We expect to visit 10 to 13 sites during the cruise. When the ROV is not in the water we will conduct other operations including multibeam surveys (with concurrent towed magnetometer, gravimeter, ADCP, and HDSS), CTD vertical and towed hydrocasts generally at locations close to the planned targets.

To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, from 20110407 to 20110509, belt transect surveys of coral population and diseases quantitative assessments were conducted, as a part of Rapid Ecological Assessments (REA), during the Pacific Reef Assessment and Monitoring Program (RAMP) cruise HA1101 in Marianas at biennial intervals by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC). During the cruise, there were 9 surveys in total conducted at REA sites around Saipan. At the specific REA sites, coral biologists along with algal biologists and marine invertebrate zoologist entered the water and conducted a fine-scale (approximately 300 m^2) and high degree of taxonomic resolution REA survey to assess and monitor species composition, abundance, percent cover, size distribution, diversity, and general health of corals, macro-invertebrates, and algae in shallow-water (less than 35 m) habitats. As a part of REA surveys, the coral belt surveys were focused on quantifying the diversity, abundance, density, and size-class distribution of the anthozoan and hydrozoan corals as well as the condition and health state of the coral reef populations. The surveys were conducted along two consecutively-placed, 25 m transect lines. The belt width was 1 m wide, 0.5 m on each side of the transect line. Within each 25 m transect, five 2.5 m segments were surveyed (beginning at points: 0, 5, 10, 15, and 20 meters), whereby in each segment, all coral colonies whose center fell within 0.5 m of either side of the transect line were identified to the lowest taxonomic level possible (genus or species) and two planar size metrics were collected: maximum diameter and diameter perpendicular to the maximum diameter. In addition, the extent of mortality, both recent and old, was estimated for each colony. Observers paid special attention to identifying as best as possible the extent of the former live colony. When a coral colony exhibited signs of disease or compromised health, additional information was recorded including type of affliction (bleaching, skeletal growth anomaly, white syndrome, tissue loss other than white syndrome, trematodiasis, necrosis, other, pigmentation responses, algal overgrowth, and predation), severity of the affliction (mild, moderate, marked, severe, acute), as well as photographic documentation and occasional tissue samples. Tissue samples were cataloged and fixed in buffered zinc-formalin solution for further histopathological analyses. Raw survey data included species presence and relative abundance, colony counts per taxon, size (width and length), mortality, predation, and health status. A surveyed area was ranging from 10 m^2 to 25 m^2 per site.

This dataset contains a 3m ESRI Grid representing the slope (in degrees) of selected portions of seafloor around Bajo de Cico in Puerto Rico, derived from data collected in 2007. 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 Puerto Rico from 4/14/07 to 4/24/07. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 (95 kHz) multibeam echosounder. 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 opened in ESRI ArcMap 9.x using the XYZ to raster tool. 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.

Raw survey data included genus presence and relative abundance, and voucher specimens. Detailed taxonomic analyses of voucher specimens are presented.
