Oceanographic CTD and Benthic Data from the Gulf of Alaska and Bering Sea, 1989-1990

Conductivity, Temperature, Depth (CTD) and benthic organism data were collected by the NOAA Ship Alpha Helix over an eight-month period from October 1989 to June 1990. The Institute of Marine Science at the University of Alaska, Fairbanks, submitted the data, which is processed into NODC's F022 and F132 file formats. This dataset captures physical and biological oceanographic conditions in two key North Pacific marine regions.

Use Cases

• Modeling water column structure based on Conductivity, Temperature, and Depth (CTD) profiles.
• Analyzing benthic organism distribution and abundance in the Bering Sea and Gulf of Alaska.
• Investigating seasonal oceanographic changes from fall to spring based on the 1989-1990 time range.
• Correlating physical oceanographic data with biological benthic observations.

Strengths

• Data collection spans a defined eight-month period from October 4, 1989, to June 26, 1990.
• Covers two distinct geographic regions: the Gulf of Alaska and the Bering Sea.
• Processed and available in standardized NODC file formats (F022 and F132).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 1990-06-26 00:00:00; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
