This dataset includes data which was collected on the R/V ALPHA HELIX cruises HX37, HX38, HX39, HX40, and HX41, in the Gulf of Alaska and Prince William Sound between 11/10/82 and 3/30/83, by Drs. Royer, Niebauer, Cooney, Shaw, and Kelley of the Institute of Marine Science. Data has been processed by NODC to the NODC standard High-Resolution CTD/STD (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.

CTD data were collected from the ALPHA HELIX from the Gulf of Alaska. Data were collected by the University of Alaska - Fairbanks; Institute of Marine Science (UAK/IMS) in support of Gulf of Alaska-1 (GAK-1) from 30 May 1995 to 25 June 1995. Parameters include profiles of temperature, salinity, fluorescence, and oxygen.

The University of Alaska is responsible for this data which was collected aboard the R/V Alpha Helix cruise HX65 between 10/29/84 - 11/03/84 by Dr. Royer of the Institute of Marine Science, and aboard the R/V Redoubt cruise RT41 between 10/14/83 - 10/24/83 by Dr. Burrell of the Institute of Marine Science. There were a total of 125 stations in the Gulf of Alaska area and 65 stations in the Boca de Quadra area. Data has been processed by NODC to the NODC standard High-Resolution CTD/STD (F022) format.

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.
