GLODAPv2: Ocean Chemistry Profiles from the North Atlantic, 1983

From May 1 to May 17, 1983, this dataset captures chemical, physical, and profile data from the R/V Oceanus cruise 32OC19830501 in the North Atlantic Ocean. It likely contains vertical profile measurements of dissolved oxygen, nitrate, nitrite, phosphate, silicate, salinity, and temperature, collected using CTD and bottle instruments. The data are part of the international GLODAPv2 synthesis project for ocean carbon and acidification research.

Use Cases

• Calibrating ocean biogeochemical models based on historical nitrate and phosphate measurements.
• Studying water mass formation and circulation using potential temperature (theta) and salinity profiles.
• Assessing baseline ocean acidification conditions from silicate and dissolved oxygen data.
• Validating satellite-derived sea surface salinity products with in-situ discrete sample data.

Strengths

• Data is part of the authoritative GLODAPv2 (Global Ocean Data Analysis Project) synthesis, a standard for ocean carbon cycle studies.
• Includes a specific, well-documented 17-day research cruise (32OC19830501) with clear temporal and spatial (North Atlantic Ocean) boundaries.
• Measures multiple core oceanographic variables (9 listed) using standard CTD and bottle methods, supporting multivariate analysis.

Limitations

• Source conflict on the lead investigator's affiliation (Woods Hole Oceanographic Institution vs. Scripps Institution of Oceanography).
• Critical metadata is missing: no row count, column names, file size, or license information is provided on any platform.
• The data is historical (from 1983), which may limit its utility for studying recent oceanographic changes.
