North Pacific Ocean Carbon Chemistry and Hydrographic Profiles from 2003

North Pacific Ocean chemical and physical data collected from the OSHORO MARU research vessel between June 3 and June 16, 2003. The dataset includes dissolved inorganic carbon, alkalinity, pH, nutrients, dissolved oxygen, temperature, and salinity from discrete bottle samples and CTD profiles. These data were collected by Nobuo Tsurushima of AIST as part of the PACIFICA international carbon synthesis project.

Use Cases

• Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
• Analyzing nutrient cycling relationships based on nitrate, phosphate, and silicate data.
• Studying water mass properties and mixing based on concurrent temperature, salinity, and oxygen profiles.
• Calibrating biogeochemical models using discrete, co-located measurements of carbon and nutrient parameters.

Strengths

• Data includes multiple co-located parameters (12 variables) for integrated analysis.
• Samples were collected during a defined research cruise (OS136-KNOT) over a 14-day period in June 2003.
• Data is part of the PACIFICA international synthesis project, suggesting standardized collection protocols.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single cruise in 2003; temporal and spatial coverage is limited.
