Bering and Chukchi Seas CTD Profiles from 1987

8800020 NCEI accession contains high-resolution CTD/STD data from three R/V THOMAS G. THOMPSON cruises in the Bering and Chukchi Seas during July and August 1987. The dataset provides nearly continuous vertical profiles of temperature, salinity, density, and other parameters at depth intervals as fine as 1 meter. Data was collected by researchers from the University of Washington and Institute of Marine Science and processed by the National Oceanographic Data Center to its standard F022 format.

Use Cases

• Analyzing vertical stratification of temperature and salinity to study water mass distribution in Arctic shelf seas.
• Calculating density (sigma-t) profiles to understand ocean circulation and mixing processes.
• Correlating dissolved oxygen or transmissivity measurements with biological productivity.
• Using station position, date, and time data to map spatial and temporal variability of ocean properties during summer 1987.
• Integrating cruise metadata and environmental conditions to contextualize cast-specific observations.

Strengths

• Data is processed to a known, documented 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 period (July-August 1987) across three research cruises in a critical Arctic region.

Limitations

• Specific row count, file size, and complete column list are not provided by any source.
• Sources conflict on the last updated date: one platform lists 2026-03-05, while another lists the collection end date of 1987-08 29.
• The presence of parameters like dissolved oxygen or transmissivity is noted as 'possibly' present, indicating potential inconsistency.
