The Conductivity, Temperature and Depth (CTD) data were collected as part of Amazon Shelf Sediment Study (AMASSEDS) project. Data was collected from NW Atlantic (limit-40 W) using ship COLUMBUS ISELIN. The data was collected over a 10 day period between August 4 to August 13, 1989. Data was submitted on a floppy disk containing 86 CTD files by Dr. Richard Limeburner, Woods Hole Oceanographic Institution (WHOI), Woods Hole, MA. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC.

The Conductivity, Temperature and Depth (CTD) and other data were collected as part of Office of Naval Research (ONR). CTD Data was collected from NW Atlantic (limit-40 W). Replacement data is provided for data collected using Ship CONRAD between May and June 1988. New data was collected using ship COLUMBUS ISELIN over a period spanning from November 22, 1990 to December 1, 1990. Data was submitted by Dr. Eli Katz, Lamont-Doherty Earth Observatory, Palisades, NY. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC.

Water physical and chemical data were collected using current meter and bottle casts from the COLUMBUS ISELIN, JOHN SMITH, and other platforms from October 23, 1975 to November 6, 1977. Data were submitted by Virginia Institute of Marine Science - Gloucester Point, as part of the Ocean Continental Shelf - Mid Atlantic (OCS - Mid Atlantic) project. Data were processed by NODC to the NODC standard Water Physical and Chemical (F014) format. The F014 format is designed to support studies of physical and chemical observations on the water column. Reported are measurements of temperature, salinity, conductivity, dissolved oxygen, nitrate, nitrite, ammonia, orthophosphate, and organic carbon. The format consists of four data record types, 80 characters in length, sorted by station and sequence numbers for proper order. The first nine columns for all records are to be used for file type (columns 1-3) and file identifier (columns 4-9). The file identifier, to be assigned by the originator, is an unique originator id for each data submission. After submission, the NODC reassigns to this field an unique NODC identifier for internal use.

Data was collected from R/V COLUMBUS ISELIN in South Atlantic Ocean and North American Coast line-South during the Amazon Shelf Sediment Study (AMASSEDS) between May 23, 1990 to June 13, 1990. The data parameters were: pressure, temperature, salinity, oxygen, fluorescence and sediment concentration. A Neil Brown Instrument Systems Model MKIII CTD was used as the primary profiling instrument. A Sea Tech 5 cm path length Transmissometer and a Sea Tech Fluorometer were mounted near the CTD fish. On some stations the Fluoro- meter was replaced with an optical backscatter sensor to observe suspended sediment concentrations above the light transmissometer limit of 0.5 gm/l. Data was submitted in two diskettes by Dr. Richard Limeburner of Woods Hole Oceanographic Institution, Woods Hole, MA. Data has been processed and is currently available in F022-CTD-Hi-Resolution file format of NODC.

Depth, pressure, salinity, temperature, and other data were collected using meteorological sensors and CTD casts in the Arctic Ocean, Greenland Sea, and North Pacific Ocean. Data were collected from NOAA Ship KA'IMIMOANA, fishing vessel Sea Watch, and USCG Healy from May 11 to November 28, 2001. Data were submitted by Pacific Marine Environmental Laboratory (PMEL) as part of the Atlantic Layer Tracking Experiment (ALTEX) project.

Meteorological and other data were collected using bottle casts and other instruments from PANULIRUS II and WEATHERBIRD in the North Atlantic Ocean. Data were collected from 09 January 1979 to 30 November 1984 by Woods Hole Oceanographic Institution with support from the Station S project.

Depth, temperature, and other data were collected from the OCEANUS from June 21, 1991 to July 4, 1991. Data were submitted by Dr. Robert Weller of the Woods Hole Oceanographic Institution. These data were collected using XBT casts in the Northeast Atlantic Ocean.

The Conductivity, Temperature and Depth (CTD) and other data were collected. R/V Oceanus was used to collect data. The data was collected from 76 stations over one month period spanning from June 15, 1983 to July 11, 1983 in NW Atlantic (limit-40 W). Data was submitted by Dr. Nelson Hogg of Woods Hole Oceanographic Institution (WHOI), Woods Hole, MA in a tape. The originator's data has been processed by NODC and is currently available in F022-CTD Hi resolution file format.

The Conductivity, Temperature and Depth (CTD) and other data were collected in NW Atlantic (limit-40 W). Data was collected from Ship OCEANUS. The data was collected over a period spanning from July 23, 1988 and August 27, 1988. Data was submitted in a tape by Woods Hole Oceanographic Institution, Woods Hole, MA. 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.
