Oceanus CTD/STD Profiles from the South Atlantic, 1983

High-resolution CTD/STD data profiles collected during the OCEANUS cruise in the South Atlantic Ocean. The dataset, processed by the National Oceanographic Data Center to its F022 standard, contains nearly continuous measurements of temperature, salinity, density, and other parameters. Data collection occurred from March 11 to April 1, 1983, under the auspices of the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing vertical profiles of temperature and salinity to study water mass structure in the Southeast Atlantic.
• Calculating density (sigma-t) from measured parameters to investigate ocean stratification and circulation.
• Correlating station data (position, date, time) with environmental conditions like meteorological observations.
• Examining potential dissolved oxygen or transmissivity records for biogeochemical or optical studies.
• Using the high-resolution (potentially 1m interval) depth/pressure data for fine-scale process studies.

Strengths

• Data is processed to a recognized standard format (NODC High-Resolution CTD/STD F022), ensuring structured consistency.
• Provides high-resolution vertical profiles, with data potentially reported at depth intervals as fine as 1 meter.
• Includes contextual metadata for each station: cruise information, position, date, time, and sampling interval.

Limitations

• Specific column names, total row count, and exact file size are not documented in the provided sources.
• Sources conflict on the dataset's last update date: one platform lists 2026-03-06, while another lists 1983-04-01.
• The presence of parameters like dissolved oxygen or transmissivity is noted as 'possibly' included, indicating potential incompleteness.
