North Pacific Ocean Carbon and Hydrographic Profiles from 1996

From 1996-05-09 to 1996-05-16, discrete water samples and profiles were collected from the HOKKO MARU in the North Pacific Ocean. The data include dissolved inorganic carbon, temperature, salinity, nitrate+nitrite, phosphate, and silicate, measured using CTD, Coulometer, and bottle instruments. These data were collected by Shuichi Watanabe of JAMSTEC; Mutsu Institute for Oceanography as part of the international PACIFICA project.

Use Cases

• Modeling ocean carbon uptake based on dissolved inorganic carbon measurements.
• Analyzing nutrient distributions (nitrate, phosphate, silicate) in the North Pacific Ocean.
• Studying relationships between hydrographic variables (temperature, salinity, pressure) and carbon chemistry.
• Calibrating and validating regional ocean biogeochemical models using profile data.

Strengths

• Data includes seven key oceanographic variables (e.g., DIC, nutrients, temperature, salinity) for a focused study.
• Data collection is associated with the international PACIFICA synthesis project, suggesting a standardized methodology.
• Specific instruments (CTD, Coulometer for DIC) are named, providing measurement context.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single, brief cruise in May 1996, limiting temporal and spatial scope.
