NOAA Ship Oscar Dyson Underway Oceanographic Data from 2017-2020

Raw underway data logged by the Scientific Computer System aboard NOAA Ship Oscar Dyson. The dataset includes biological, chemical, meteorological, navigational, optical, and physical time series measurements collected in the Arctic Ocean, Beaufort Sea, Bering Sea, and North Pacific Ocean from January 2017 to September 2020. Office of Marine and Aviation Operations personnel submitted the data and supplementary cruise-level metadata from the Ship Daily Activity Log to the National Centers for Environmental Information via the NOAA Rolling Deck to Repository program.

Use Cases

• Modeling Arctic Ocean biogeochemistry based on underway chemical and biological measurements.
• Analyzing vessel-based meteorological trends in the Beaufort and Bering Seas.
• Correlating physical oceanographic conditions with biological observations across the cruise time series.
• Studying ship-track navigational data for spatial analysis of sampling efforts.

Strengths

• Data spans a multi-year time range from 2017-01-20 to 2020-09-18.
• Covers a broad geographic scope including the Arctic Ocean, Beaufort Sea, Bering Sea, and North Pacific Ocean.
• Includes multiple data domains: biological, chemical, meteorological, navigational, optical, and physical.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last updated 2020-09-18 00:00:00; freshness should be verified.
