The water depth and temperature data were collected in arctic west from ship POLAR STAR between August 11, 1992 and October 6, 1992. The originator's bathythermograph (XBT) data were submitted on a diskette by Ms. Diane Foster of US Coast Guard, Groton CT. The data have been converted and are now available on line in C116 (XBT) file format of NODC. The data type C116 contained temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data record was comprised of pairs of temperature-depth values. The XBT data files contained temperature values at non-uniform depths. These depths were recorded at the minimum number of points ("inflection points") required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m.

This dataset contains data collected from 80 casts in NW Atlantic (limit-40 W) as part of Shipboard Environmental data Acquisition System (SEAS) III program. The cruises were conducted using ship POLAR STAR. The bathythermograph (XBT) data was collected between June 9, 1991 and October 23, 1991. The data were sent from the cruise ships to the US Coast Guard, Groton CT via telecommunication. This data was submitted in a diskette and is currently available in the C116 file format of NODC.

This dataset includes discrete sample and profile data collected from USCGC POLAR STAR in the Arctic Ocean from 2002-08-19 to 2002-09-23. These data include Barium, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-113 (CFC-113), CHLOROFLUOROCARBON-12 (CFC-12), DISSOLVED OXYGEN, Delta Oxygen-18, HYDROSTATIC PRESSURE, NITRATE, NITRITE, Potential temperature (theta), SALINITY, WATER TEMPERATURE, phosphate and silicate. The instruments used to collect these data include CTD and bottle. These data were collected by Rebecca A. Woodgate of University of Washington; Applied Physics Laboratory (APL) as part of the PACIFICA_32PZ20020819 dataset. CDIAC associated the following cruise ID(s) with this dataset: CBL 2002 (AWS-02-II) and PACIFICA_32PZ20020819 PACIFICA (PACIFic ocean Interior CArbon) was an international collaborative project for the data synthesis of ocean interior carbon and its related parameters in the Pacific Ocean. The North Pacific Marine Science Organization (PICES), Section of Carbon and Climate (S-CC) supported the project.

The water depth and temperature data was collected in Beaufort Sea and Chukchi Sea from ship POLAR STAR by the US COAST GUARD. The data was collected between July 20, 1993 and October 10, 1993. One diskette of originator's Arctic west bathythermograph (XBT) data from summer of 1993 was submitted to NODC. The data has been copied to current storage media of NODC.

The water depth and temperature data was collected from ship Polar Star. The data was collected from November 2, 1989 to April 11, 1990 as part of project Deep Freeze. The originator's bathythermograph (XBT) data was submitted in two diskettes by US Coast Guard, Groton, CT. The data has been converted and is now available on line in C116 file format of NODC.

Temperature profile and water depth data were collected using BT and XBT casts from the USCGC POLAR STAR in the Northwest Atlantic Ocean. Data were collected from 21 June 1987 to 05 July 1987 by the US Coast Guard. Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) format. The C116/C118 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data record was comprised of pairs of temperature-depth values. Unlike the MBT Data File, in which temperature values were recorded at uniform 5 m intervals, the XBT data files contained temperature values at non-uniform depths. These depths were recorded at the minimum number of points ("inflection points") required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Prior to July 1994, XBT data were routinely processed to one of these standard types. XBT data are now processed and loaded directly in to the NODC Ocean Profile Data Base (OPDB). Historic data from these two data types were loaded into the OPDB.

A 35-day NSF-sponsored cruise aboard the USCGC Polar Star has studied in depth the physical oceanography of the Chukchi Borderland and Mendeleev Ridge regions. An extensive hydrographic survey (126 CTD casts) was conducted. In addition to CTD profiles of temperature, conductivity, oxygen, and light scatter and L-ADCP profiles of water velocity, bottle samples were taken for nutrients (2662 samples), dissolved oxygen (2999 samples), salinity (3066 samples) and tracers CFCs (F11, F12, F113, ca. 2500 samples), O18 isotopes (ca.1000 samples), Barium (ca.1000 samples), Helium (ca.108 samples), Iodine-129 (96 samples) and Cesium-137 (27 samples). Twenty-one denitrification (N:Ar ratio) samples were also taken. A total of 47 XBTs were used both to increase spatial coverage over the shelf and to increase spatial resolution in the slope regions. To better map the boundary current regime, 3 oceanographic moorings carrying current meters and temperature and salinity sensors were deployed across the boundary current for the ca. 1 month duration of the cruise. During the cruise, via a website of daily updates from a High School teacher aboard the Polar Star and visits to schools in Barrow, we brought Arctic research into the classroom. Post-cruise a multi-institute team of scientists will study this extensive data set, with reference to previous (sparse) measurements, Canadian measurements taken this year in the Canadian Basin and near Northwind Ridge, and modeling results, to understand the role of this Arctic Crossroads in the circulation of the Arctic Ocean.

This dataset includes chemical, discrete sample, physical and profile data collected from USCGC POLAR STAR in the Arctic Ocean and Beaufort Sea from 2002-07-15 to 2002-08-13 and retrieved during cruise CARINA/32PZ20020715. These data include HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHOSPHATE, SALINITY, SILICATE and WATER TEMPERATURE. The instruments used to collect these data include CTD and bottle. These data were collected by Robert S. Pickart of Woods Hole Oceanographic Institution as part of the CARINA/32PZ20020715 dataset. The CARINA (CARbon dioxide IN the Atlantic Ocean) data synthesis project is an international collaborative effort of the EU IP CARBOOCEAN, and U.S. partners. It has produced a merged internally consistent dataset of open ocean subsurface measurements for biogeochemical investigations, in particular, studies involving the carbon system. The original focus area was the North Atlantic Ocean, but over time the geographic extent expanded and CARINA now includes data from the entire Atlantic, the Arctic Ocean, and the Southern Ocean.

In February 1963, the U.S. Geological Survey (USGS) began a study of heat flow in the Arctic Ocean Basin and acquired data at 356 sites in Canada Basin and Nautilus Basin and on Alpha-Mendeleev Ridge by the end of the project in 1973. The USGS heat flow and associated piston coring operations were conducted from a scientific station on the freely drifting T-3 Ice island (also known as Fletcher's Ice Island). The Naval Arctic Research Laboratory (NARL) had established T-3 as a drifting research station in 1962 and, along with the Office of Naval Research, kept it operating continuously until September 28, 1974. The USGS heat flow studies were part of the scientific effort supported by the NARL.

The water depth and temperature data was collected in South Pacific Ocean as part of project Deep Freeze from ship POLAR STAR. The data was collected from November 8, 1992 to April 12, 1993. The originator's bathythermograph (XBT) data was submitted in a diskette by Ens. Quenton Maddux, US COAST GUARD, Groton, CT. The data has been converted and is now available on line in C116 file format of NODC.
