WOCE P02T: Ocean Carbon and Hydrographic Profiles from the North Pacific, 1994

WOCE_P02T cruise data from the KAIYO-MARU research vessel includes 14 chemical and physical variables like dissolved inorganic carbon, pH, alkalinity, and chlorofluorocarbons. These discrete sample and profile observations were collected in the North Pacific Ocean and Philippine Sea between January 7 and February 10, 1994. Tsuneo Ono of the Hokkaido National Fisheries Research Institute collected the data as part of the World Ocean Circulation Experiment, which aimed to understand the ocean's role in climate.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
• Analyzing deep water circulation patterns using chlorofluorocarbon (CFC-11, CFC-12) tracer data.
• Studying nutrient cycles in the Pacific Ocean based on nitrate, phosphate, and silicate concentrations.
• Calibrating ocean biogeochemical models using concurrent measurements of alkalinity, oxygen, and hydrostatic pressure.

Strengths

• Includes 14 precisely named chemical and physical variables relevant to carbon cycle and climate research.
• Data is part of the standardized World Ocean Circulation Experiment (WOCE) program, spanning 1990-1998.
• Specifies the exact research vessel (KAIYO-MARU), chief scientist, and a precise 35-day collection period.

Limitations

• Column-level documentation and sample data are unavailable, requiring field semantics to be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment for large-scale modeling.
• Data is from a single cruise in 1994, limiting temporal and spatial generalizability.
