NOAA Ship Oscar Dyson Underway Oceanographic Data from Southeast Alaska, January 2021

Raw underway biological, chemical, meteorological, navigational, optical, and physical data logged by the Scientific Computer System aboard NOAA Ship Oscar Dyson. The data was collected in the Coastal Waters of Southeast Alaska and British Columbia over a three-day period from January 29 to 31, 2021. Office of Marine and Aviation Operations personnel submitted the data and associated cruise-level metadata to the National Centers for Environmental Information via the NOAA Rolling Deck to Repository program.

Use Cases

• Modeling coastal water properties based on the described chemical and physical data streams.
• Analyzing short-term meteorological trends in a coastal marine environment based on the logged meteorological data.
• Correlating biological and optical measurements for phytoplankton or water clarity studies based on the described data types.
• Studying ship-track navigation and environmental parameter time series for data integration methods.

Strengths

• Data covers multiple oceanographic domains (biological, chemical, meteorological, navigational, optical, physical) in a single collection.
• Includes supplementary cruise-level metadata from the Ship Daily Activity Log.
• Data is archived through an automated process under the NOAA R2R program, suggesting standardized collection.

Limitations

• Row count, column definitions, and file formats are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data covers only a three-day period, which may limit analysis of longer-term trends.
