North Atlantic Ocean CTD/STD Profiles from SUB SIG II Cruise

High-resolution conductivity-temperature-depth and salinity-temperature-depth data collected during the SUB SIG II cruise in the North Atlantic Ocean. The dataset, processed by the National Oceanographic Data Center to the F022 standard, contains nearly continuous vertical profiles of oceanographic parameters. It is published by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing vertical profiles of temperature and salinity to study water mass structure.
• Investigating density (sigma-t) variations for ocean circulation modeling.
• Correlating station position, date, and time with meteorological conditions recorded during casts.
• Examining dissolved oxygen or transmissivity data for biogeochemical studies.
• Using high-resolution data reported at intervals as fine as 1 meter for detailed process studies.

Strengths

• Data is processed to the NODC's standardized High-Resolution CTD/STD (F022) format, ensuring consistency.
• Profiles provide nearly continuous measurements at depth intervals as fine as 1 meter.
• Includes cruise metadata, position, date, time, and environmental conditions for each station.
• Covers a defined time range from December 11, 1978, to August 23, 1979, in the North Atlantic.

Limitations

• Exact row count, column names, and file size are unknown from available sources.
• Data values may be subject to averaging, filtering, or interpolation as noted in the format description.
• Conflicting 'last updated' dates exist between platforms (2026-03 06 on Data.gov vs. 1979-08-23 on NASA Earthdata).
