Ammonium, nitrate, nitrite, phosphate, silicate, and urea data were collected from R/V ALPHA HELIX from July 13, 1985 to October 14, 1985. 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 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.

Zooplankton, salinity, fluorescence, and temperature data were collected from the ALPHA HELIX from July 22, 1999 to August 14, 1999. Data were submitted by University of Alaska - Fairbanks; Institute of Marine Science. Data were collected using oblique tows in Bering Sea.

The University of Alaska is responsible for this data which was collected aboard R/V Alpha Helix cruise HX59, R/V Amak cruise AM04, and R/V Redoubt cruises RT31 - RT41, between 12/1/82 - 03/24/84, by Dr. George Hunt of the University of California, Irvine, and Dr. Burrell of the Institute of Marine Science. There were a total of 120 stations in the Bering Sea area, and a total of 448 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. 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 Conductivity, Temperature and Depth (CTD) and other data were collected in Gulf of Alaska and Bering Sea as part of Inner SHelf Transfer and recycling (ISHTAR) project. Data was collected from Ships ALPHA HELIX and LITTLE DIPPER. The data was collected over a period spanning from June 27, 1994 to January 6, 1995. 7 sets of CTD data collected from seabird from 13 stations was received by NODC from Dr. C. Peter McRoy of University of Alaska, Institute of Marine Science, Fairbanks, AK via FTP. Data is 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.

Conductivity, Temperature and Depth (CTD) and other data were collected in Bering Sea as part of Inner SHelf Transfer and recycling (ISHTAR) and "St. Lawrence Island Polynya" project. Data was collected from Ship ALPHA HELIX cruise HX-177. The data was collected over a period spanning from May 3, 1994 and June 8, 1994. Dr. Jackie Grebmeier, Univ. of Tenn., Knoxville was Principal Investigator funded by NSF Grant OPP-9000694. Data from 105 stations was received by NODC via Dr. Chirk Chu, University of Alaska, Institute of Marine Science, Fairbanks, AK. Data is in F022-CTD-Hi Resolution file format of NODC.
