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.

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.

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.

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.

Nitrate, nitrite, phosphate, silicate, and other data were collected from R/V ALPHA HELIX and THOMAS G. THOMPSON from April 17, 1987 to July 21, 1988. Data were submitted by University of Alaska - Fairbanks; Institute of Marine Science and California Department of Fish and Game as part of the Inner Shelf Transfer and Recycling Project. Data were collected using bottle casts in the Gulf of Alaska, Bering Sea, and Northeast Pacific Ocean.

Nutrients and physical data were collected from R/V THOMAS WASHINGTON and R/V OSHORU MARU from June 12, 1986 to October 19, 1988. 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 (ISHTAR) project. Data were collected using bottle and CTD casts in Gulf of the Alaska, Bering Sea, and Northeast Pacific Ocean.

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.

Chemical and depth data were collected from the ALPHA HELIX from September 7, 1987 to June 11, 1988. Data were submitted by the University of Alaska - Fairbanks; Institute of Marine Science and California Department of Fish and Game. Data were collected using bottle casts in the Bering Sea.

The Conductivity, Temperature and Depth (CTD) and other data were collected in Bering Sea. Data was collected from Ship ALPHA HELIX cruise HX 171. The data was collected over a period spanning from June 12, 1993 and July 1, 1993. Data from 81 stations was submitted in a diskette by Dr. Chirk Chu, Institute of Marine Science, University of Alaska, Fairbanks, AK. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC. F022 High-resolution CTD data is collected from high resolution (conductivity-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 1 m. 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.
