High-Resolution CTD/STD Profiles from North Atlantic SUB SIG II Cruise

Two months of high-resolution conductivity-temperature-depth (CTD) and salinity-temperature-depth (STD) data from the North Atlantic Ocean SUB SIG II cruise between November 13, 1977, and January 16, 1978. The dataset has been processed by the National Oceanographic Data Center (NODC) into the standard F022 format, providing nearly continuous vertical profiles of oceanographic parameters. It originates from the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing vertical profiles of temperature and salinity at depth intervals as fine as 1 meter.
• Studying computed water density (sigma-t) variations across the surveyed region.
• Correlating oceanographic cast data with reported meteorological and sea surface conditions.
• Examining cruise track and station data including position, date, time, and sampling intervals.

Strengths

• Data is in a standardized, high-resolution NODC format (F022) designed for profile analysis.
• Covers a specific two-month research cruise, providing a temporally bounded snapshot.
• Includes multiple derived parameters like computed density (sigma-t) alongside core measurements.
• Contains detailed metadata per station including position, time, and environmental conditions.

Limitations

• Specific column names, row counts, and file sizes are not provided by the sources.
• Sources conflict on the last updated date: one lists 2026-03 05, another lists the end date of the cruise (1978-01-16).
• The presence of parameters like dissolved oxygen or transmissivity is noted as 'possibly' included, indicating potential incompleteness.
