High-Resolution CTD/STD Data from R/V Knorr Atlantic Cruise

NOAA_NCEI provides high-resolution Conductivity-Temperature-Depth and Salinity-Temperature-Depth data from the R/V Knorr research cruise in the Caribbean Sea, North Atlantic, and South Atlantic Oceans. The dataset covers a specific voyage from December 2, 1982, to February 18, 1983, and has been processed to the NODC standard F022 format. It offers nearly continuous vertical profiles of key oceanographic parameters.

Use Cases

• Analyzing vertical profiles of temperature and salinity for oceanographic research.
• Studying water density (sigma-t) variations across different ocean regions.
• Investigating dissolved oxygen or water clarity (transmissivity) at specific depth levels.
• Correlating cruise station data with concurrent meteorological and sea surface conditions.

Strengths

• Data is processed to a known standard format (NODC F022), ensuring consistency.
• Provides high-resolution profiles with depth intervals as fine as 1 meter.
• Includes ancillary data such as cruise information, position, date, time, and environmental conditions.

Limitations

• Specific column names, row counts, and dataset size are not provided by the sources.
• Sources conflict on the last updated date, with one listing 2026-03-05 and another 1983-02-18.
• License information is not specified.
