NOAA Ship Oscar Dyson Underway Oceanographic Data in the Gulf of Alaska, March 2021

NOAA Ship Oscar Dyson collected raw underway biological, chemical, meteorological, navigational, optical, and physical data in the Gulf of Alaska from March 3 to March 16, 2021. Office of Marine and Aviation Operations personnel submitted these data and supplementary cruise-level metadata from the Ship Daily Activity Log. The data were archived through the NOAA Rolling Deck to Repository (R2R) automated process.

Use Cases

• Modeling oceanographic conditions based on underway physical and chemical measurements
• Analyzing biological activity patterns based on logged biological data
• Correlating meteorological observations with oceanographic data for integrated environmental studies
• Validating satellite or model data using in-situ navigational and optical measurements

Strengths

• Data covers multiple domains (biological, chemical, meteorological, navigational, optical, physical) from a single cruise
• Includes supplementary cruise-level metadata from the Ship Daily Activity Log
• Collected over a specific 14-day period (2021-03-03 to 2021-03-16) in the Gulf of Alaska

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Last updated 2021-03-16; freshness should be verified for current applications
• Row count and file formats are unknown, which may limit suitability assessment
