WOCE P09 Cruise Ocean Chemistry Profiles from the Pacific, 1994

The Bismarck Sea, North Pacific Ocean, Philippine Sea, and South Pacific Ocean are covered by chemical and physical oceanographic data collected during the Ryofu Maru II cruise WOCE_P09 from July to August 1994. The dataset includes measurements for dissolved inorganic carbon, chlorofluorocarbons, isotopes, nutrients, and physical properties from approximately 23,000 stations across 94 WOCE cruises between 1990 and 1998. These data were collected by Masao Ishii of the Meteorological Research Institute using CTD and bottle instruments.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon measurements.
• Tracing water mass age and circulation patterns based on chlorofluorocarbon (CFC-11, CFC-12) and helium isotope data.
• Studying nutrient cycles and biological productivity based on nitrate, phosphate, and silicate concentrations.
• Calibrating and validating climate models using the comprehensive physical profile data including potential temperature and salinity.

Strengths

• Data is part of the authoritative World Ocean Circulation Experiment (WOCE), a major international climate research program.
• Covers multiple ocean basins (Bismarck Sea, North Pacific, Philippine Sea, South Pacific) during a defined cruise.
• Includes a suite of 17 chemical, physical, and isotopic variables relevant for climate studies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for this specific accession is unknown, which may limit suitability assessment.
