High-Resolution Oceanographic CTD/STD Data from the Bering Sea and Gulf of Alaska

High-resolution CTD and STD instrument data from the ACONA research vessel in the Bering Sea and Gulf of Alaska, processed by the NODC to its F022 standard format. The dataset contains nearly continuous vertical profiles of temperature, salinity, density, and other parameters at depth intervals as fine as 1 meter. Data collection occurred between July 14, 1978, and June 12, 1979.

Use Cases

• Analyzing vertical profiles of temperature and salinity to study water mass distribution.
• Examining density (sigma-t) calculations to understand ocean stratification and mixing.
• Using cruise, position, date, and time data to map environmental conditions spatially and temporally.
• Investigating potential dissolved oxygen or transmissivity records for biogeochemical insights.

Strengths

• Data is processed to a recognized standard (NODC High-Resolution CTD/STD F022 format).
• Provides high-resolution vertical profiles with sampling intervals as fine as 1 meter.
• Covers a specific, focused time range (July 1978 to June 1979) for the ACONA cruise.

Limitations

• Key metadata like row count, column names, and exact file size are unknown.
• The NASA Earthdata platform provides no descriptive information, limiting cross-validation.
• Data freshness is unclear; a 2026 update timestamp conflicts with a 1979 end date.
