NE Atlantic Hydrographic and CFC Measurements from R/V Endeavor Cruise 143

Northeast Atlantic data from 100 hydrographic stations south of the Azores, collected aboard R/V ENDEAVOR from May 1-19, 1987. The dataset contains CTD-derived pressure, depth, temperature, salinity, dissolved oxygen, and potential temperature, alongside measurements of dissolved chlorofluorocarbons Freon-11 and Freon-12. It was provided by Dr. T. Joyce of the Woods Hole Oceanographic Institution.

Use Cases

• Tracing historical ocean circulation patterns based on chlorofluorocarbon (CFC) concentrations.
• Calibrating or validating ocean biogeochemical models using in-situ hydrographic data.
• Analyzing water mass properties (temperature, salinity, oxygen) from CTD casts at 100 stations.
• Studying the penetration of anthropogenic tracers (Freon-11, Freon-12) into the ocean in the late 1980s.

Strengths

• Contains measurements from 100 discrete hydrographic stations, providing spatial coverage.
• Includes two key anthropogenic tracers (Freon-11 and Freon-12) alongside standard CTD parameters.
• Data provenance is clearly stated, originating from a named research cruise (R/V ENDEAVOR #143) and principal investigator.

Limitations

• Metadata completeness is low: column names, row count, file size, and license are unspecified across all sources.
• Data is from a single cruise in 1987, limiting temporal scope and modern relevance.
• A conflict exists in the temporal metadata: the title lists 1986-05-01 to 1986-05-19, while the description states May 1-19, 1987.
