WOCE I05: Indian Ocean Chemical and Physical Profiles from 1987

NCEI Accession 0157468 includes chemical, physical, and profile data from the R/V Charles Darwin in the Indian Ocean from November to December 1987. The data were collected by researchers from the Woods Hole Oceanographic Institution as part of the World Ocean Circulation Experiment (WOCE) I05 survey. Measurements include chlorofluorocarbons, dissolved oxygen, nutrients, salinity, water temperature, and hydrostatic pressure, obtained using CTD and bottle instruments.

Use Cases

• Modeling ocean circulation and water mass formation based on salinity and temperature profiles.
• Studying historical distributions of anthropogenic tracers like CFC-11 and CFC-12.
• Analyzing nutrient cycles (nitrate, phosphate, silicate) in the Indian Ocean.
• Calibrating or validating ocean biogeochemical models using dissolved oxygen and nutrient data.

Strengths

• Data is part of the major World Ocean Circulation Experiment (WOCE) program, which aimed to better understand the ocean's role in climate.
• Includes multiple chemical and physical variables (e.g., CFCs, nutrients, dissolved gases, temperature, salinity) measured concurrently.
• Associated with a specific, documented research cruise (74AB29/WOCE_I05_1987) with known principal investigators.

Limitations

• Last updated 1987-12-17 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
