Philippine Sea Oceanographic Profiles from 1991 Cruise

From June 26 to July 4, 1991, this dataset contains chemical and physical oceanographic measurements collected from the R/V Ocean Researcher I in the Philippine Sea. The data includes parameters such as chlorofluorocarbons (CFC-11, CFC-12), dissolved oxygen, nutrients (nitrate, nitrite, phosphate, silicate), salinity, and water temperature. It was collected by researchers from National Taiwan University as part of the international PACIFICA project.

Use Cases

• Modeling historical ocean carbon uptake based on CFC-11 and CFC-12 measurements.
• Analyzing water mass structure and circulation in the Philippine Sea based on salinity and temperature profiles.
• Studying nutrient distributions and ocean productivity based on nitrate, phosphate, and silicate data.
• Calibrating or validating ocean biogeochemical models using this multi-parameter observational dataset.

Strengths

• Includes multiple key oceanographic parameters (CFCs, nutrients, oxygen, temperature, salinity) for integrated analysis.
• Data has precise temporal (1991-06-26 to 1991-07 04) and spatial (Philippine Sea) coverage.
• Collected as part of a defined international scientific project (PACIFICA), suggesting structured protocols.

Limitations

• Last updated 1991-07-04 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.
