Ocean CTD Cast Profiles from the Northwest Atlantic Ocean, 1982

Northwest Atlantic Ocean data profiles were collected from the R/V Oceanus during a 1982 cruise. The dataset contains high-resolution measurements of temperature, salinity, pressure, dissolved oxygen, and light transmission processed to the NODC F022 standard. It was gathered by the US Geological Survey as part of the Ocean Continental Shelf - Georges Bank project.

Use Cases

• Analyzing vertical temperature and salinity stratification in the Northwest Atlantic using depth/pressure level data.
• Investigating relationships between light transmission (transmissivity) and other water column properties like density (sigma-t).
• Studying dissolved oxygen profiles for biogeochemical assessments in a continental shelf environment.
• Using cruise station metadata (position, date, time) for spatial and temporal analysis of oceanographic conditions.

Strengths

• Data is processed to the NODC standard High-Resolution CTD/STD (F022) format, ensuring a consistent structure.
• Profiles provide nearly continuous measurements at fine depth intervals, potentially as fine as 1 meter.
• Includes multiple key oceanographic parameters: temperature, salinity, pressure, density, dissolved oxygen, and light transmission.

Limitations

• Exact row count, column names, and dataset size are unknown across all sources.
• Sources conflict on the temporal coverage: one states data collection from 1982-01-19 to 1982-02-03, while others state 1982-01 29 to 1982-02-03.
