High-Resolution CTD/STD Oceanographic Data from 1982 Bering Sea Expedition

National Oceanic and Atmospheric Administration data contains high-resolution CTD and STD instrument profiles from the REDOUBT and RV Alpha Helix research vessels. The dataset covers the Bering Sea, Coastal Waters of Southeast Alaska and British Columbia, and the Gulf of Alaska during a summer cruise from June to September 1982. It has been processed to the NODC standard High-Resolution CTD/STD (F022) format.

Use Cases

• Analyzing vertical profiles of temperature and salinity to study water mass structure.
• Calculating density (sigma-t) from measured parameters to understand ocean stratification.
• Correlating environmental conditions (e.g., dissolved oxygen) with biological observations.
• Examining spatial variability across the Bering Sea, Gulf of Alaska, and coastal British Columbia.
• Using station metadata (position, date, time) for cruise track reconstruction and temporal analysis.

Strengths

• Data provides high-resolution profiles with depth intervals as fine as 1 meter.
• Coverage includes multiple distinct regions: Bering Sea, Gulf of Alaska, and coastal Southeast Alaska/British Columbia.
• Data is standardized to a recognized format (NODC F022), ensuring consistent structure.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the 'last updated' date, with one showing 2026 and another 1982.
• License information is not available, restricting clarity on reuse terms.
