North Atlantic CTD Data from Transient Tracers Study 1981

April to October 1981 data from the Transient Tracers in the Ocean-North Atlantic study, collected aboard the RV Knorr. The dataset covers legs 1-7 of the study, including stations 1-250, and was submitted by R.T. Williams, F. Delahoyde, and K.M. Sanborn of the Scripps Physical and Chemical Oceanographic Data Facility. Data is stored in a non-NODC format across seven original tapes.

Use Cases

• Analyzing vertical profiles of pressure, temperature, and salinity from 250 ocean stations.
• Studying the distribution of transient tracers for ocean circulation model validation.
• Investigating seasonal hydrographic changes in the Northwest Atlantic from April to October.
• Providing a historical baseline for comparative studies of North Atlantic water masses.

Strengths

• Covers a specific 7-month research cruise with a clear time range from April 1 to October 19, 1981.
• Includes data from 250 distinct oceanographic stations across legs 1-7 of the study.
• Originates from a recognized oceanographic facility (Scripps) with documented submitters.

Limitations

• Critical metadata conflicts exist: the 'last updated' date is reported as both 1981-10 19 and 2026-03-06.
• No column names, row counts, file size, or specific data license are provided by any source.
• Data is stored in a legacy 'non-NODC format' on seven physical tapes, indicating potential access challenges.
