Caribbean Sea CTD Profiles from 1980 Cruise

High-resolution oceanographic profiles were collected by the vessel JEAN A. in the Caribbean Sea over a five-day cruise from June 17 to June 21, 1980. The data, processed by the National Oceanographic Data Center (NODC) into the F022 format, contain nearly continuous measurements of temperature, salinity, and density at fine depth intervals. This dataset represents a specific snapshot of ocean conditions from a NOAA NCEI-managed research cruise.

Use Cases

• Analyzing vertical profiles of temperature and salinity (sigma-t density) for water mass identification.
• Studying short-term oceanographic conditions during a specific cruise, using station metadata like position, date, and time.
• Investigating relationships between measured parameters like potential dissolved oxygen or transmissivity and physical properties.
• Using the detailed, near-continuous depth-series data as a baseline for comparison with modern oceanographic observations.

Strengths

• Data provides high-resolution profiles with depth intervals as fine as 1 meter.
• Information is structured to the documented NODC standard F022 format, ensuring consistent organization.
• Dataset includes contextual cruise and station metadata such as position, date, time, and environmental conditions.

Limitations

• The exact row count, column names, and file size are not provided by any source.
• Sources conflict on the 'last updated' date, with one listing 2026-03 06 and another listing 1980-06-21.
• The presence of specific parameters like dissolved oxygen or transmissivity is noted as 'possibly' reported, not guaranteed.
