This dataset contains primarily sea temperatures data and salinity records resultant from NMFS Alaska Fisheries Science Center groundfish bottom trawl surveys, Bering Sea, Gulf of Alaska and U.S. west coast surveys, from approx. Aug. 1976 to Sept. 1997. The records in the file EVENT.LST tie directly to the records in the file PROFILE.LST, keying on vessel, cruise and event. Also, the PROFILE.LST cruises are in no particular order, for example, the data records begin with a 1982 Bering Sea cruise made by the vessel Pat San Marie. The files are ASCII text and were extracted from the NMFS RACEBase Oracle data base.

This dataset contains time series measurements of temperature and salinity at the GAK1 site at the mouth of Resurrection Bay near Seward, AK from December 1999 through October 2002. Instrument packages were deployed at 6 depth levels.

The University of Alaska, Institute of Marine Science is responsible for these data collected aboard the R/V Alpha Helix on cruises HX123, HX124, HX125, and HX126, between May 5, 1989, and June 10, 1989. These data were collected for the Exxon Oil Spill Monitoring Program and the Gulf of Alaska Recirculation (GARS) Project. Funding was provided by the State of Alaska, Sea Grant, and the National Science Foundation. This data was submitted to NODC earlier. This dataset represents a resubmission due to fact that the earlier version had the wrong offsets applied. Field correction for the STD data was derived by comparing single bottle samples to recorded values from the STD sensors. The field correction is based on 15 samples from a total of 16 stations. The field corrections are: 3000 m CTD temperature mean (Nansen-STD) is 0.00536 and 3000 m CTD salinity mean (Nansen-STD) is -0.04131. Data has been processed by NODC to the NODC standard High-Resolution STD/CTD Data (F022) format. 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.

The Institute of Marine Science, University of Alaska is responsible for this data collected on R/V Little Dipper cruises LO37-LO56 from 03/01/95 to 02/06/98 by Dr. Tom Royer of the Institute of Marine Science. The data was collected for the "Oceanographic Time Series in North Pacific" project funded by NOAA, Grant No. NA90AA-D-AC805. There was a total of 2 stations in the Resurrection Bay and Gulf of Alaska area. Data has been processed to the NODC standard High-Resolution STD/CTD Data (F022) format. 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.

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.

CTD and other data were collected from the Bering Sea from the ALPHA HELIX from 15 September 1985 to 22 September 1985. Data were collected by the University of Alaska - Fairbanks / Institute of Marine Science (UAK/IMS) as part of the Inner Shelf Transport and Recycling (ISHTAR) project. Data include temperature and salinity profiles.

Depth, fluorescence, oxygen, salinity, and water temperature data were collected from R/V ALPHA HELIX from September 17, 1986 to September 25, 1986. Data were submitted by University of Alaska - Fairbanks; Institute of Marine Science and California Dept of Fish and Game as part of the Inner Shelf Transport and Recycling Project (ISHTAR). These data were collected using CTD casts in the Bering Sea.

Current meter and pressure gauge data were collected using moored current meter casts and other instruments in the Gulf of Alaska from April 22, 1989 to September 26, 1989. Data were submitted by Pacific Marine Environmental Laboratory (PMEL) as part of the Fisheries-Oceanography Coordinated Investigations (FOCI) project. Data has been processed by NODC to the NODC standard F015- Current Meter Data and F017- Pressure Gauge formats. 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. The F017 format contains time series measurements of seawater pressure from anchored or bottom-mounted sensors. Measurements of variations at depth of seawater pressure provide information on tidal and storm flows, ocean circulation, and other phenomena that cause changes in sea surface elevation or slope and that can be detected from their pressure signature. Position, bottom depth, and gauge depth are reported for each station. The data record comprises values of total pressure at specified date and time. Data values may be subject to averaging or filtering and are typically reported at time intervals of 10-15 minutes. Seawater temperature may also be reported. Comments may be reported in a text record.

Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) format. The C116/C118 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. Prior to July 1994, XBT data were routinely processed to one of these standard types. XBT data are now processed and loaded directly in to the NODC Ocean Profile Data Base (OPDB). Historic data from these two data types were loaded into the OPDB.
