High-Resolution CTD/STD Ocean Profiles from 1972-1973

From May 1972 to October 1973, this dataset contains high-resolution conductivity-temperature-depth (CTD) and salinity-temperature-depth (STD) profiles collected by research vessels ANTON DOHRN II, JEAN CHARCOT, LA PERLE, and LE NOROIT in the Bay of Biscay, North Atlantic Ocean, and Norwegian Sea. The data was processed by the National Oceanographic Data Center (NODC) into the standard F022 format, providing nearly continuous vertical measurements of ocean properties. It includes cruise metadata, station positions, and environmental conditions recorded during the casts.

Use Cases

• Analyzing vertical profiles of temperature, salinity, and computed density (sigma-t) to study water mass structure.
• Investigating spatial and temporal variability of oceanographic conditions in the Bay of Biscay and Norwegian Sea using station position and time data.
• Calibrating or validating ocean models with high-resolution, quality-controlled historical measurements.
• Studying dissolved oxygen or light transmissivity trends if those parameters are included in the specific data records.

Strengths

• Provides high-resolution vertical profiles with sampling intervals as fine as 1 meter.
• Data is processed and standardized to the NODC F022 format, ensuring a consistent structure.
• Covers a specific time range (1972-1973) across multiple oceanographic regions with documented vessel and cruise information.

Limitations

• Specific column names, row counts, and dataset size are unknown from the provided sources.
• License information is not provided, which restricts clarity on usage rights.
• Potential data processing includes averaging, filtering, or interpolation, as noted in the format description.
