North Pacific Ocean CTD/STD Profiles from 1984

North Pacific Ocean data contains high-resolution vertical profiles of temperature, salinity, and density from the SWAN cruise in 1984. The dataset is processed by the National Oceanographic Data Center (NODC) into the standard F022 format, with measurements reported at intervals as fine as 1 meter. It is hosted by NOAA NCEI and also appears on NASA EarthData, indicating cross-platform relevance.

Use Cases

• Analyzing vertical structure of the ocean water column using temperature, salinity, and density (sigma-t) profiles.
• Studying spatial and temporal variability of physical oceanographic conditions in the North Pacific during 1984.
• Correlating subsurface measurements with reported surface meteorological and sea surface condition data from the cruise.
• Using cruise, station, position, date, and time metadata for voyage-based research and data provenance.

Strengths

• Data provides high-resolution profiles with sampling depth intervals as fine as 1 meter.
• Processed to a consistent, documented standard (NODC F022 format) ensuring structured interoperability.
• Includes ancillary metadata such as cruise information, position, and environmental conditions for context.

Limitations

• Exact row count, column names, and total dataset size are not provided by any source.
• Temporal coverage is limited to a single cruise spanning approximately seven months in 1984.
• Conflicting 'last updated' dates exist between sources (2026-03-06 on Data.gov vs. 1984-08-03 on NASA).
