High-Resolution CTD/STD Oceanographic Profiles from the North Atlantic

NCEI Accession 8800210 contains high-resolution conductivity-temperature-depth (CTD) and salinity-temperature-depth (STD) data processed by the NODC to its F022 standard format. Data was collected during cruises of the R/V Knorr and OCEANUS in the Northwest Atlantic Ocean from June to August 1977. The dataset likely contains nearly continuous vertical profiles of temperature, salinity, density, and possibly dissolved oxygen or transmissivity at depth intervals as fine as one meter.

Use Cases

• Analyzing vertical stratification and water mass properties based on temperature and salinity profiles.
• Studying seasonal oceanographic conditions in the Northwest Atlantic during summer 1977.
• Calibrating or validating oceanographic models using high-resolution in-situ measurements.
• Investigating relationships between surface meteorological conditions and subsurface ocean structure, as environmental data may be reported.

Strengths

• Data is processed to a recognized standard format (NODC F022), suggesting consistent quality control.
• Provides high-resolution vertical profiles, with data potentially reported at 1-meter intervals.
• Covers a specific, focused time period (1977-06-11 to 1977-08-21) from two research vessels.

Limitations

• Column names and exact data structure are not provided in the available metadata.
• Conflicting 'last updated' dates exist between platforms (2026 vs. 1977), creating uncertainty about metadata maintenance.
• The dataset's age (from 1977) may limit its utility for studying contemporary oceanographic changes.
