Chemical and isotopic tracers and other data from the Arctic Ocean from 1990-01-01 to 1999-12-31 (NCEI Accession 0068667)
These data are water column and sediment data largely collected in the Bering and Chukchi Seas, with some coverage for the Beaufort and East Siberian Seas, and with limited coverage for other portions of the Arctic Ocean. Data include that collected on Alpha Helix cruises 139, 165, 166, 174,189, 190, 214, and 224 between 1990 and 1999. Other data were obtained from cruises of the RV OKEAN (1993), USCGC Polar Star (1993), Mendeleev (1993), USCGC Polar Sea (2000), U.S. Canada Arctic Ocean Section (1994), and Polarstern (1993). Water column data include coverage from some to most stations on these cruises, and include bottle salinity, temperature, sigma-t, oxygen-18/16 ratios, phosphate, ammonia, silicate, nitrate, dissolved oxygen, iodine-129 concentrations, and chlorophyll a. Sediment data include plutonium and neptunium concentrations, including isotope data. Biological data include radionuclide burdens in marine mammal tissues donated by subsistence hunters on the North Slope of Alaska and in the Resolute region of Canada.

This dataset includes data which was collected on the R/V ALPHA HELIX cruise HX53 between 10/4/83 - 10/5/83 by Dr. Henrichs of the Institute of Marine Science. There were a total of 15 stations in the Aialik Bay & Resurrection Bay area. This dataset also includes data which was collected on the R/V Alpha Helix cruise HX54 between 10/24/83 - 10/29/83 by Dr. Royer of the Institute of Marine Science. There were a total of 110 stations in the Gulf of Alaska area. This dataset also includes data which was collected on the R/V OSHORO MARU cruise OSM95 between 6/30/83 - 7/9/83 by Ray Hadley of the Institute of Marine Science. There were a total of 14 stations in the Pacific Ocean. Finally, this dataset includes data which was collected on the R/V ALPHA HELIX cruise HX49 between 8/15/83 - 8/21/83 by Dr. McRoy of the Institute of Marine Science. There were a total of 50 stations in the Bering Sea & Chukchi Sea 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.
