North Atlantic Ocean High-Resolution CTD and STD Profiles from 1985

High-resolution CTD and STD data from the North Atlantic Ocean, collected by the ENDEAVOR and R/V Knorr research vessels between March and November 1985. The dataset provides nearly continuous vertical profiles of temperature, salinity, and other parameters, processed by the National Oceanographic Data Center (NODC) into the standard F022 format. Data values are reported at fine depth intervals, potentially as fine as 1 meter.

Use Cases

• Analyzing vertical structure of temperature and salinity for water mass identification.
• Calculating density (sigma-t) profiles to study ocean stratification and stability.
• Correlating environmental parameters like dissolved oxygen with physical properties at specific stations.
• Studying temporal changes in oceanographic conditions during the 1985 cruise period.
• Using station position, date, and time metadata for spatial and temporal analysis of hydrographic data.

Strengths

• High-resolution data with potential sampling at 1-meter depth intervals, enabling detailed profile analysis.
• Processed to a recognized standard (NODC F022 format) ensuring consistency and interoperability.
• Covers a defined 8-month time range (1985-03-19 to 1985-11-29) in the North Atlantic Ocean.
• Includes metadata for cruise, instrument, position, date, time, and environmental conditions at each station.

Limitations

• Exact row count, file size, and specific column names are not provided by any source.
• Conflicting 'last updated' dates: datagov reports 2026-03-05 (likely a metadata update), while nasa_earthdata reports the original collection end date of 1985-11-29.
• License information is not available from any source, restricting clarity on reuse terms.
