The NOAA Coral Reef Watch Experimental Ocean Acidification Product Suite (OAPS) offers an important synthesis of satellite and modeled environmental datasets to provide a synoptic estimate of sea surface carbonate chemistry in the Greater Caribbean Region. This tool complements ongoing geochemical surveys and monitoring efforts in the region by providing estimates of changing ocean chemistry on a broader spatial and temporal scale than shipboard observations alone can permit. The maps presented here are monthly averages of daily estimates derived according to Gledhill et al., 2008. Near-real-time estimates are modeled from daily fields of NOAA Optimum Interpolation Advanced Very High Resolution Radiometer - Advanced Microwave Scanning Radiometer (AVHRR-AMSRE) SST, Hybrid Coordinate Ocean Model + Navey Coupled Ocean Data Assimilation (HYCOM + NCODA) modeled sea surface salinity (SSS), NOAA National Centers for Environmental Predication (NCEP) sea-level pressure (SLP), and estimates of atmospheric CO2 derived from the NOAA Earth System Research Laboratory GLOBALVIEW-CO2 reference marine boundary layer (MBL). The parameters provided in this data set include sea surface temperature (SST), sea surface salinity (SSS), partial pressure of carbon dioxide for seawater (pCO2sw), total alkilinity (TA), total inorganic carbon (TC), pH, aragonite saturation state (SSA), bicarbonate ion concentration (HCO3), and carbonate ion concentration (CO3). All parameters are provided at monthly, 25km resolution.

Oceanographic station data were collected from the MELLON within a 1-mile radius of Ocean Weather Station V (3400N 16400E) and in transit. Data were collected by the United States Coast Guard (USCG) from 04 August 1968 to 19 August 1968. Data were processed by NODC to the NODC standard Station Data II Output Format (SD2). Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/sd2.html. The SD2 format contains physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5 percent) were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters and temperature and salinity , but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t) sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels.

To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, from 19 August - 30 September 2003, marine invertebrate quantitative assessments were conducted, as part of Rapid Ecological Assessments (REA), during the Reef Assessment and Monitoring Program (RAMP) Cruise OES0307 in the Marianas Archipelago. Such cruises are conducted at biennial intervals by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC). At specific reef sites, marine invertebrate zoologists along with coral and algal biologists entered the water and conducted a fine-scale (~100 m2) and high degree of taxonomic resolution benthic REA survey for coral, algae, and key invertebrate species. Invertebrate surveys were focused on quantifying key non-coral invertebrate species common to the reef habitats, and were conducted using a combination of different survey techniques to quantify the diverse communities. These methods included belt-transect surveys, roving-swim surveys, and quadrat surveys. In belt-transect surveys, quantitative counts of key invertebrates were recorded along two consecutively-placed 25m long and 2m wide belt transects (total area = 100 m2). For any species that cannot be identified in the field, a photograph and a representative specimen, if possible, is collected for later identification. Roving-swim surveys were conducted in the general area with the goal to collect qualitative data for rare, larger, and cryptic organisms, such as Crown of Thorns Starfish and Triton's Trumpet snails which may not be seen during belt-transect surveys, and to survey any additional habitats present at the site, e.g. sand, sea grass, pavement, etc. This was accomplished by swimming a zig-zag pattern that extends roughly 5 m on either side of the two transect lines (total length = 500 m). Quadrat surveys were used to quantify the smaller, more cryptic invertebrates which were sometimes overlooked or too numerous to count during belt-transect surveys. Ten 0.25-m2 quadrats were laid out at 2-m intervals along two of the 25-m transects (total area = 5 m2). For each quadrat the percent cover of sponges, octocorals and zoanthids was recorded, as well as urchins, hermit crabs of the genus Calcinus, trapezid crabs, and coralliophilid snails. In addition, up to 25 cm diameters of all urchin species are measured. Based on data from previous REA surveys, a group of target invertebrate species was chosen for quantitative counts at 6 REA sites at Anatahan Island in the Marianas Archipelago. The species in the list were chosen because they have been shown to be common components of the reef habitats and they are species that are generally visible (i.e.; non-cryptic) and easily enumerated during the course of a single 50-60 minute SCUBA survey.

This dataset contains a space-delimited ASCII XYZ text file with easting, northing, and depth in meters values for the bathymetry of the north shore of St. Croix, US Virgin Islands and southwest shore (La Parguera) of Puerto Rico. XYZ values are derived from a 10 m resolution gridding process. 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 US Virgin Islands and Puerto Rico from 3/21/06 to 4/2/06. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam 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 and zoning from NOAA COOPS. Data is in UTM zone 20 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle, and was exported as an ASCII XYZ file. 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.

Because rockfish (Sebastes spp.) are physoclystic, i.e. their gas bladders are closed off from the gut, they often suffer internal injuries from rapid, internal air expansion when caught and brought to the surface. Many discarded rockfish do not survive either because they cannot submerge due to excessive buoyancy or because of internal damage. There is some evidence that recompression may greatly increase the survival of barotrauma-injured rockfish. However, because survival can be species-specific it is important to gauge the impacts on each species of interest. Research completed in 2010 on a small NOAA vessel demonstrated that rougheye rockfish (S. aleutianus), caught at depths down to 700 feet and exhibiting barotrauma, can survive if recompressed after capture in portable pressurized tanks. This result is noteworthy because it is the deepest known successful capture and recompression of any rockfish species, which suggests theres potential to conduct scientific tagging studies to track movements and behavior. In 2011 and 2012 we chartered a longline vessel to sample rougheye rockfish on reefs nearby the NOAA, the Auke Bay Laboratories (ABL), Little Port Walter Research Station on the southeast side of Baranof Island. After rougheye were caught and brought to the surface, they exhibited signs of barotrauma such as stomach eversion, exophthalmia (bulging eyes), and corneal gas bubbles. Of 43 fish that were recompressed immediately after capture in portable pressure tanks, 25 survived and are currently held at TSMRI for long term monitoring. The deepest fish that was captured and has survived long-term was caught at ~915 feet. Some fish still have corneal gas bubbles, but other signs of barotrauma have since subsided. Other rougheye rockfish were tagged and released at 250 ft using a weighted crab ring and a downrigger (n=130).

Preliminary hard and soft seafloor substrate map derived from an unsupervised classification of multibeam backscatter and bathymety derivatives at Pagan Island, Commonwealth of the Northern Mariana Islands (CNMI). The dataset was derived using Reson 8101 backscatter data, bathymetric variance and bathymetric rugosity. The sonar frequency is 240 kHz for the Reson 8101 backscatter data, which were resampled to a 5 m grid cell size prior to the classification. Limited seafloor photographs for groundtruthing are available for Guam and therefore no supervised classification was performed and we are unable to visually or quantitatively evaluate the accuracy of the unsupervised classification seafloor substrate map. However, in locations such French Frigate Shoals, NWHI and Tutuila, American Samoa, where ground truth data are available, the unsupervised classification method is a robust predictor of substrate type in similar depth ranges and seafloor environments.
