This dataset consists of helium and tritium data submitted by Woods Hole Oceanographic Institution (WHOI) as part of the Transient Tracers in the Ocean Funding Organization (TTO) North Atlantic Survey and NATS (North Atlantic Tracer Section) programs. The TTO data was collected during 7 legs of the R/V Knorr from April to October 1981. The NATS data was collected during legs 1-3 of the Atlantis from June to September 1981. The TTO program has reference number L00944 and the NATS program has a reference number of L00945. These programs were supported by NSF grants OCE79-21378 and OCE81-17998.

This entry contains the results from the Outer Continental Shelf Study (OCS) benchmark study in the North Atlantic which ran November to December 1977 from the R/V KNORR. These data were submitted by Energy Resources Co., Inc. in fulfillment of BLM contract #AA550-CT6-51. This data contains eleven files with different file types and therefore different reference numbers. The following is a description of the files and a listing of the reference numbers: file 1 labeled L01001, L130 contains nutrients, temp., sal. and do data; file 2 labeled L00991, L513 contains %silt, %clay, %grain size, %carbon and %nitrogen in sediments; file 3,4 labeled L00992, L521 contains tax. code, counts, egg/larvae; file 5 labeled L00993, L134 contains metals in zooplankton, water, sediment, macrobenthos; file 6 labeled L00994, L131 contains lipids, hydrocarbons in water, zooplankton, macrobenthos, sediment, surface film; file 7,8,9 labeled L00995, L504 contains macrobenthic taxonomy codes and counts.

Temperature profile, salinity, pressure, and oxygen data were collected using CTD casts from the KNORR in the Southeast Atlantic Ocean. Data were collected from 13 November 1983 to 10 December 1983 by Lamont - Doherty Geological Observatory with support from the Agulhas Retroflection Cruise (ARC) project. Data has been processed by NODC to the NODC standard High-Resolution CTD/STD (F022) and Ocean Station (C100) formats. The Oceanographic Station Data (C100) format contains physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5 percent) were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters and temperature and salinity, but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t) sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels. 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.

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.

This dataset includes discrete sample and profile data collected during the R/V Knorr KN199-04, GEOTRACES-2010 cruise (EXPOCODE 316N20101015) in the North Atlantic Ocean from 2010-10-15 to 2010-11-05. These data include CTD temperature, salinity, oxygen and nutrients. The instruments used to collect these data include CTD, Niskin bottles and spectrophotometer.

These data were received courtesy of Dr. Eric D'Asaro, Univ. of Washington/Applied Physics Lab and result from the recent Labrador Sea experiment, R/V Knorr cruise KN156. Data sets transmitted include 33 "complete" CTD stations, both up and down casts, unaveraged, 32 accompanying oxygen and salinity "bottle" data files and 23 CTD pressure and oxygen data calibrated to bottles. In addition, there are 5 accompanying documentation or informational files including a DDF form. All files transmitted are ASCII or ASCII text.

Temperature and conductivity profile data were collected using STD/CTD casts from KNORR in the Atlantic Ocean from October 3, 1976 to October 19, 1976. Data were submitted by Woods Hole Oceanographic Institution as part of the International Decade of Ocean Exploration / combination of USSR POLYGON project and US MODE (IDOE/POLYMODE) project. Data were 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.
