Equatorial Pacific Ocean Chemistry and Physics Profiles from 1979-1980

The Equatorial Pacific region was sampled for physical and chemical oceanographic parameters from February 1979 to June 1980. Lamont-Doherty Earth Observatory collected bottle cast data, including profiles of temperature, salinity, and nutrients like oxygen, phosphate, nitrate, and silicate. The dataset also contains carbon system measurements such as partial CO2, total CO2, alkalinity, and isotopic tracers.

Use Cases

• Modeling historical ocean carbon uptake based on partial and total CO2 concentration profiles.
• Analyzing nutrient limitation patterns in equatorial waters based on phosphate, nitrate, and silicate concentrations.
• Studying water mass properties and stratification using temperature, salinity, and sigma-t profiles.
• Investigating ocean ventilation and tracer transport using tritium and Delta C-14 measurements.
• Calibrating or validating biogeochemical models with alkalinity and Delta C-13 data.

Strengths

• Includes multiple nutrient profiles (oxygen, phosphate, nitrate, nitrite, silicate) for biogeochemical analysis.
• Contains carbon system parameters (partial CO2, total CO2, alkalinity, Delta C-13) relevant for climate studies.
• Covers a specific time range from 07 February 1979 to 14 June 1980.
• Data was collected by the authoritative Lamont-Doherty Earth Observatory of Columbia University.

Limitations

• Last updated 1980-06-14; 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.
