North Atlantic CTD/STD Profiles from 1968-1969

High-resolution conductivity-temperature-depth (CTD) and salinity-temperature-depth (STD) profiles collected from the R/V GERDA and USNS SCHUYKILL in the North Atlantic Ocean. The dataset, processed by the National Oceanographic Data Center (NODC) into the F022 format, provides nearly continuous measurements of temperature, salinity, and density at depth intervals as fine as 1 meter. Data collection occurred between February 20, 1968, and May 14, 1969.

Use Cases

• Analyzing vertical profiles of temperature and salinity for water mass identification.
• Studying historical oceanographic conditions in the North Atlantic during the late 1960s.
• Calibrating or validating ocean models with high-resolution in-situ measurements.
• Examining relationships between computed density (sigma-t) and other measured parameters.

Strengths

• Data is processed to a documented standard format (NODC F022), ensuring a consistent structure.
• Provides high-resolution profiles with sampling intervals as fine as 1 meter, offering detailed vertical information.
• Includes metadata for each station such as cruise information, position, date, time, and environmental conditions.

Limitations

• Key metadata such as row count, specific column names, file size, and license are unavailable from the provided sources.
• The temporal coverage is limited to a specific 15-month period from 1968 to 1969.
