High-Resolution Ocean CTD/STD Profiles from ACONA Cruise

High-resolution oceanographic profiles from the ACONA cruise in the Bering Sea, Gulf of Alaska, and North Pacific Ocean. The data, processed by the NODC into the F022 format, includes nearly continuous measurements of temperature, salinity, conductivity, and density at depth intervals as fine as 1 meter. Collection occurred during a specific cruise from September to December 1979.

Use Cases

• Analyzing vertical profiles of temperature and salinity for water mass identification.
• Studying ocean density (sigma-t) structure and stratification across the Bering Sea and Gulf of Alaska.
• Investigating correlations between measured parameters like dissolved oxygen or transmissivity and location/date.
• Using reported cruise, station, position, date, and time data to map the spatial and temporal coverage of the observations.
• Examining reported meteorological and sea surface conditions for context on the sampling environment.

Strengths

• Data is in a standardized, high-resolution format (NODC F022) with depth intervals as fine as 1 meter.
• Provides nearly continuous profiles of multiple key oceanographic parameters from a defined research cruise.
• Includes contextual metadata such as position, date, time, and environmental conditions for each station.

Limitations

• The exact row count, column names, and dataset size are unknown from the provided sources.
• Conflicting last updated dates exist between platforms (2026-04-01 on Data.gov vs. 1979-12-12 on NASA Earthdata).
• License and author information is not specified in any source.
