North Atlantic Ocean Currents and CTD Profiles from 1981

Salinity, sigma-t, and temperature data were collected from moored current meters and CTD casts in the North Atlantic Ocean from August 29, 1981 to December 7, 1981. The data were submitted by the National Ocean Service (NOS) and processed by the NODC into standard formats for current meter, high-resolution CTD, and wave wind spectra data. The dataset likely contains time-series measurements of ocean currents and near-continuous vertical profiles of water column properties.

Use Cases

• Analyze time-series of ocean current speed and direction based on moored current meter data.
• Study vertical profiles of temperature, salinity, and density (sigma-t) based on CTD cast data.
• Investigate relationships between meteorological conditions and ocean waves based on the wave wind spectra format.
• Model water mass formation and mixing in the North Atlantic based on the collected physical parameters.

Strengths

• Data collection spans a specific 101-day period from August to December 1981.
• Data is processed to three established NODC standard formats (F005, F022, F191).
• The description specifies high-resolution CTD profiles, potentially at depth intervals as fine as 1 meter.

Limitations

• Last updated 1981-12-07 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
