North Atlantic CTD/STD Profiles from DISCOVERY Cruises

High-resolution oceanographic profiles collected in the North Atlantic Ocean by the R/V DISCOVERY between 1977 and 1983. The dataset contains processed conductivity-temperature-depth and salinity-temperature-depth data in the NODC F022 standard format. It was processed and published by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing vertical profiles of temperature and salinity to study water mass structure.
• Calculating density (sigma-t) from temperature and salinity columns for stability analysis.
• Investigating temporal changes in ocean properties over the six-year cruise period.
• Correlating station data (position, date, time) with surface meteorological conditions.
• Examining potential dissolved oxygen or transmissivity records for biogeochemical insights.

Strengths

• Data provides high-resolution profiles with depth intervals as fine as 1 meter.
• Covers a multi-year time series from 1977-01-13 to 1983-07-31 for temporal analysis.
• Processed to a standardized format (NODC F022) ensuring consistent structure.
• Includes ancillary station metadata like cruise information, position, and sampling intervals.

Limitations

• Exact row count, file size, and complete column list are not provided by sources.
• Sources conflict on last update date: one states 2026-03-05, another states 1983-07 31.
• License information is not specified across any platform.
