Water physics and chemistry data were collected using moored current meter and bottle casts in the Northwest Atlantic Ocean from May 28, 1982 to June 4, 1982. Data were submitted by National Ocean Service (NOS) as part of the North East Monitoring Program (NEMP) project. Data were processed by NODC to the NODC standard Water Physics and Chemistry Data (F004) format. Full water physics and chemistry descriptions are available at http://www.nodc.noaa.gov/General/NODC-Archive/f004.html. The F004 format is used for data from measurements and analyses of physical and chemical characteristics of the water column. Among chemical parameters that may be recorded are salinity, PH, and concentration of oxygen, ammonia, nitrate, phosphate, chlorophyll, and suspended solids. Physical parameters that may be recorded include temperature, density (sigma-t), transmissivity, and current velocity (east-west and north-south components). Cruise and station information, including environmental conditions of the study site at the time of observations, is also included.

Data from Coral Reef Ecosystem Division (CRED), NOAA Pacific Islands Fisheries Science Center (PIFSC) Subsurface Temperature Recorders (STR) provide a time series of water temperature at coral reef sites. Data is typically collected at 1800 second intervals for a duration of 2 years using a SBE39 Temperature Recorder (Sea-Bird Electronics, Inc., www.seabird.com). When a STR is recovered, a new one is typically deployed in the same place. Time series data combining multiple deployments from a given site may also be available.

Temperature profile data were collected using XBT and BT casts from the NOAA Ship RESEARCHER and other platforms in a world-wide distribution from 18 August 1982 to 21 December 1982. Data were collected by the US NAVY; Ships of Opportunity. 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.

Bathythermograph data were collected from the MENDOTA within a 1-mile radius of Ocean Weather Station C (5245N 0350W) and in transit. Data were collected by the United States Coast Guard from 03 July 1967 to 07 August 1967. The platform was equipped and staffed to observe weather and sea conditions. 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 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.

A total of 70 stations were occupied. The standard FOCI grid and line 8 were samped. At each station we sampled using paired 20 and 60 cm Bongo frames (150 and 500 micron mesh nets, respectively). A SeaBird SeaCat (SBE 19 plus) was used with the bongo frames to determine the depth of the samplers in real time and to measure temperature and conductivity. On line 8 CTD casts were also taken. We left Dutch Harbor at 2300 on May 31 (GMT time) and arrived at our first grid station, GV147, at approximately 0500 on June 2. The deployment and retrieval of both the 60 cm bongo and the neuston gear were successful until the weather conditions became too severe to continue sampling our planned grid stations on the evening of June 2 after station 13 (HH151) was completed. Operations were resumed at GV151 on June 4 at 0200 until another storm made sampling conditions difficult after station 55 (HD 165) on June 7 at 0330. We waited in Alitak Bay on the south end of Kodiak Island to resume sampling. Since so much sampling time had already been lost due to weather, it was decided to abandon the rest of the planned grid stations below Shelikof Strait and steam to Line 8 and resume sampling there. We arrived at the first Line 8 station and began sampling at 2230 on June 7. After all six of the Line 8 stations were completed, we resumed sampling at designated grid stations until it was necessary to head into port on June 9.

Our scheduled departure time was delayed due to a combination of weather and shipb??s equipment problems (navigation light, engine). The weather slowed our transit time to Bering Site 2 from approximately 19 hrs to more than 29 hours. Bering Sea Site 2 - When we arrived at site 2, we began CTD/chlorophyll/nutrient/oxygen and bongo ops at the southernmost box station. The station was successfully completed and we slowly b?? due to weather b?? made our way to the westernmost box station b?? averaging between 5 and 6 knots. This station was also successfully completed, but shipb??s personnel concluded that due to a combination of the weather and personnel inexperience in the challenging sea conditions, operations would be suspended. After a safety meeting among shipb??s personnel, it was decided that the survey person, would monitor the operations area for safety considerations. Deployment and recovery of gear that was normally performed by a survey tech and deck hand would now be done by a scientist and a deck hand. Operations resumed at mid-morning - CTD/chlorophyll/nutrient/oxygen and bongo ops at the remaining box stations were completed. The center station was completed with 2 CTD/chlorophyll/nutrient/oxygen/DIC casts, a bongo and triplicate CalVET tows. We waited overnight hoping for improving weather conditions, but in the morning concluded that we should head north to Bering Sea site 5. Bering Sea Site 5 b?? We deployed 2 subsurface moorings (mooring recoveries at this site had been conducted previously on a contract vessel). A CTD/chlorophyll/nutrient/oxygen/DIC casts, a bongo and triplicate CalVET tows were completed after mooring operations. We then completed the box of stations surrounding site 5 b?? with a CTD/chlorophyll/nutrient/oxygen and bongo at each station. Bering Sea Site 4 b?? We deployed 2 subsurface moorings (there were no moorings to be recovered at this site). Two CTD/chlorophyll/nutrient/oxygen/DIC casts, a bongo and triplicate CalVET tows were completed after mooring operations. We then completed the box of stations surrounding site 4 b?? with a CTD/chlorophyll/nutrient/oxygen and bongo at each station. Bering Sea Site 2 b?? A small boat was launched to recover the fragile instruments on the surface buoy tower. A surface mooring and two subsurface moorings were successfully recovered. Two subsurface moorings were successfully deployed. Three CTD/chlorophyll/nutrient/oxygen/DIC casts were completed. CTD and bongo line b?? A line of eight CTD/chlorophyll/nutrient/oxygen and bongo tows - starting at site 2 and working towards site 4 - were completed. The last seven casts included DIC samples.

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) are conducted by the Coral Reef Ecosystem Division (CRED) of the NOAA Pacific Islands Fisheries Science Center (PIFSC) as part of Pacific Reef Assessment and Monitoring Program (RAMP) Cruises. 7 towboard surveys (totaling 15.21 km in length) were conducted at Niihau in Main Hawaiian Islands from 20101007 to 20101105 as part of RAMP Cruise HA1008. 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., crown of thorns sea stars, giant clams), and for assessing trends in these populations and metrics. A pair of scuba divers (1 fish diver 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 15 m. 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 (greater than 50 cm total length) seen within 5 m either side and 10 m 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.

Bathymetry for Pensacola Bay was derived from nine surveys containing63,172 soundings. Six surveys were omitted because they were notconsistent with the other nine surveys and they were not continuous. Theaverage separation between soundings was 77 meters. The surveys dated from1934 to 1991. Approximately 70 percent of the surveys were from 1935. Asurvey from 1982 and a survey from 1991 lie in the southwest section ofthe bay. The range of soundings for the nine surveys was 0.2 to -19.8 metersat mean low water. A mean high water value of 0.4 meters was assigned to theshoreline. Eight points were found that were not consistent with thesurrounding points. These were removed prior to tinning. DEM grid valuesoutside the shoreline (on land) were assigned null values (-32676).Pensacola Bay has nine 7.5 minute DEMs and two one degree DEMs. The 1degree DEMs were generated from the higher resolution 7.5 minute DEMswhich covered the estuary. A Digital Elevation Model (DEM) contains aseries of elevations ordered from south to north with the order ofthe columns from west to east. The DEM is formatted as one ASCIIheader record (A- record), followed by a series of profile records(B- records) each of which include a short B-record header followedby a series of ASCII integer elevations (typically in units of 1centimeter) per each profile. The last physical record of the DEM isan accuracy record (C-record).The 7.5-minute DEM (30- by 30-m data spacing) is cast on theUniversal Transverse Mercator (UTM) projection. It provides coveragein 7.5- by 7.5-minute blocks. Each product provides the samecoverage as a standard USGS 7.5-minute quadrangle but the DEMcontains over edge data. Coverage is available for many estuaries ofthe contiguous United States but is not complete.

Physical, meteorological, and other data were collected from surface sensors and CTD casts from the NOAA Ship DISCOVERER and other platforms. Data were collected by the Pacific Marine Environmental Laboratory (PMEL) as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 30 January 1981 to 02 June 1981. Data were processed by NODC to the NODC standard F022 High-Resolution CTD/STD Output Format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f022.html. An analog file for this accession is available from NODC user services. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.
