Physical and nutrient profile data were collected using bottle casts from R/V ALPHA HELIX in the Gulf of Alaska from April 6, 1989, to April 11, 1989. Data were submitted by Dr. Thomas C. Royer of University of Alaska - Fairbanks; Institute of Marine Science. Data were collected by using bottle casts in the Gulf of Alaska.

Profile nutrients and other data were collected from R/V ALPHA HELIX from August 16, 1983 to July 30, 1989. Data were submitted by University of Alaska - Fairbanks; Institute of Marine Science and California Department of Fish and Game. These data were collected using bottle casts in the Gulf of Alaska, Bering Sea, and Northeast Pacific Ocean.

Temperature, salinity, and sigma-t profiles from CTD and bottle casts from the R/V ALPHA HELIX. Data were collected in the Gulf of Alaska by the University of Alaska; Institute of Marine Science (UAK/IMS) from 05 May 1989 to 28 May 1989. Data were collected in support of the Exxon Oil Spill Monitoring Program funded by the State of Alaska and the Gulf of Alaska Recirculation Project funded by the National Science Foundation, Grant #OCE8608125. Data were processed by NODC to the NODC standard F022 High-Resolution CTD/STD Output 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.

Chemical data were collected using bottle casts from multiple vessels in the Arctic Ocean and other Sea areas from 16 April 1948 to 17 September 2000. Data were submitted by the University of Alaska in Fairbanks, Alaska. Chemical data include alkalinity, nitrate, nitrite, oxygen, silicate, and phosphate.

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 F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments.

Nutrients profile data were collected from R/V ALPHA HELIX, THOMAS WASHINGTON, and THOMAS G. THOMPSON from August 12, 1980 to July 17, 1987. Data were submitted by University of Alaska - Fairbanks; Institute of Marine Science, California Department of Fish and game, and Scripps Institution of Oceanography (SIO) as part of the AJAX project. Data were collected using bottle and CTD in the Bering Sea and Northeast Pacific Ocean.

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.

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.

Nitrate, nitrite, phosphate, silicate, and other data were collected from R/V ALPHA HELIX from July 4, 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). Data were collected using bottle casts in the Bering Sea.
