In 2002, the US Naval Oceanographic Office (NAVOCEANO) submitted these data to NODC in accordance with a Memorandum of Agreement between NODC and NAVOCEANO to exchange Public Domain Data annually. These data are all data that NAVOCEANO added to their Master Oceanographic Observation Data Set (MOODS) since they last submitted MOODS data to NODC. This submission includes temperature, salinity, and sound velocity profile data collected world-wide with CTD, STD, XBT, MBT, AXBT, and bottles from August 3, 1946 to April 27, 2002.

The Master Oceanographic Observation Data Set (MOODS), maintained by the Naval Oceanographic Office (NAVOCEANO), Stennis Space Center, Mississippi, is the standard Navy database for oceanographic observations. Data contained in MOODS include observations of thermal and chemical properties of the water column from surface to bottom, the biota and currents in the water column, and the underlying sea floor as collected by oceanographic agencies worldwide. Five ACII files of depth/temperature profile data from August 31, 1991 and March 31, 1995 were submitted by Mr. Robert S. Rushton. Data received by NODC via Mr. Richard J. Enkoji via FTP.

Data has been processed by NODC to the NODC standard Current Meter (Components) (F015) and High-Resolution CTD/STD (F022) formats. The F015 format is used for time series measurements of ocean currents. These data are obtained from current meter moorings and represent Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth, and meter characteristics are reported for each station. The data record comprises values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north and negative directions west and south. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Water temperature, pressure, and conductivity or salinity may also be reported. A text record is available for optional comments. 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 sound velocity and other data in this accession has been processed by NODC from a tape submitted by the originator containing Inverted Echo Sounder data from the R/V Endeavor cruise 205, October 1989. It also contains data previously sent to NODC for the Seasonal Equatorial Atlantic (SEQUAL) project for sites Sal and Sol. These data are in NODC format for pressure gauge data (F017) and the format described in the documentation. The file Sal represents observations from several deployments (overlap of instruments) therefore there are duplicates in the data. These data have been released by Dr. Eli Katz from Lamont-Doherty Geological Observatory. CTD data was also sent and can be found under track numbers TV5152-TV5154. Data has been re-processed and re-submitted on March 24, 1991. A01402 W18760 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.

The sound velocity data in this accession were collected from unknown platforms in May 1972 by Japanese. The sound velocity in water is analog profiles data that was recorded in stripcharts by Japanese. Radio logs are forms that contain time, weather latitude/longitude, vessel id, ship id, etc. These are radioed every two hours to some military center. One line per strip chart. Some strip charts have time/date/ship id/latitude/longitude annotated on the strip chart. Twenty two stripcharts and radio logs were submitted to NODC by Hydrographic Division, Maritime Safety Agency, Tokyo, Japan.

The sound velocity data in this accession were collected on October 29, 1994 by US Navy. The sound velocity in water is analog profiles data that was recorded in stripcharts. Radio logs are forms that contain time, weather latitude/longitude, vessel id, ship id, etc. These are radioed every two hours to some military center. One line per strip chart. Some strip charts have time/date/ship id/latitude/longitude annotated on the strip chart. One stripchart and radio log was submitted to NODC by the US Navy, San Diego, CA.

Temperature profile and sound velocity data were collected using CTD, XCTD, and XBT casts in the Arctic Ocean, Mediterranean Sea - Eastern Basin, North Pacific Ocean, South Pacific Ocean, and Southern Oceans from April 11, 1975 to August 31, 1998. Data were collected by the US Naval Oceanographic Office as part of the Master Oceanographic Observation Data Set (MOODS) project.

The sound velocity data in this accession were collected in November 1994 by US Navy. The sound velocity in water is analog profiles data that was recorded in stripcharts. Radio logs are forms that contain time, weather latitude/longitude, vessel id, ship id, etc. These are radioed every two hours to some military center. One line per strip chart. Some strip charts have time/date/ship id/latitude/longitude annotated on the strip chart. Eleven stripcharts and radio logs were submitted to NODC by the US Navy, San Diego, CA.

The accession contains one Ocean Acoustic Tomography data set. The sound velocity was collected by Peter Worcester of Scripps Institution of Oceanography, La Jolla, CA between May 1, 1987 and September 30, 1987. The data was submitted by Dr. Brian Dushaw, University of Washington via FTP. The data was received by NODC via Sid Stillwaugh. Each file contains all of the ray travel-time data collected by a source/receiver pair during the experiment (three transceivers, six files). The file is broken into three sections: 1) 1st section is a one line text record describing the parameters of the experiment. 2) 2nd section is six lines describing properties of the resolved ray paths. Each column of this section describes the properties of a ray path which corresponds to the same column of travel times of the third section. 3) 3rd section contains the time of transmission (in yearday) and the ray travel times. Each line is a year day and a set of travel times of ray arrivals. Each column is a time series of ray travel times for the ray path which was described in the corresponding column of the second section.
