Pacific Equatorial Ocean Current Meter Time Series 1981-1983

NOAA NCEI provides current meter components data collected by Oregon State University for the Pacific Equatorial Ocean Dynamics (PEQUOD) project. The dataset contains Eulerian time-series measurements of east-west (u) and north-south (v) current vectors, along with potential temperature, pressure, and salinity readings, recorded at 10-15 minute intervals from fixed platforms. Measurements span a period from January 17, 1981, to March 1, 1983, and are stored in the NODC standard F015 format.

Use Cases

• Analyzing equatorial Pacific current vector components (u, v) over a two-year period.
• Correlating water temperature and salinity data with current flow patterns at fixed sensor depths.
• Validating ocean circulation models using Eulerian method measurements from moorings.
• Studying time-series data structure and sensor characteristics documented in the F015 format.

Strengths

• Data covers a continuous 26-month time range from 1981 to 1983.
• Measurements follow a standardized NODC F015 format with documented specifications.
• Data includes multiple parameters: current vectors, temperature, pressure, and salinity.
• Collection supports a specific research project (PEQUOD) with defined methodology.

Limitations

• Exact row count, file size, and complete column list are unavailable from all sources.
• Platforms disagree on the last updated date (1983-03-01 vs. 2026-03 06).
• License information is not provided by any source.
