PACIFICA Ocean Interior Carbon Data from KEIFU MARU Cruise, 2006

PACIFICA_49FA20060614 includes biological, chemical, and physical profile data collected from the KEIFU MARU in the North Pacific Ocean, Philippine Sea, and South Pacific Ocean from 2006-06-14 to 2006-07-27. These data include ALKALINITY, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, NITRATE, pH, SALINITY, and WATER TEMPERATURE. The data were collected by Kenzou Isa and Masao Ishii as part of the PACIFICA international collaborative project for ocean interior carbon synthesis.

Use Cases

• Modeling ocean acidification impacts based on pH and alkalinity measurements.
• Studying marine biogeochemical cycles based on nitrate, phosphate, silicate, and dissolved organic carbon data.
• Analyzing ocean interior carbon storage based on dissolved inorganic carbon and chlorofluorocarbon measurements.
• Investigating phytoplankton biomass based on chlorophyll a and phaeophytin data.
• Calibrating oceanographic models based on CTD-derived salinity, temperature, and hydrostatic pressure profiles.

Strengths

• Data covers a specific cruise (PACIFICA_49FA20060614) over a 44-day period in 2006.
• Includes over 20 distinct chemical, biological, and physical parameters relevant to ocean carbon research.
• Data collection was part of an international collaborative project (PACIFICA) supported by PICES.

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.
• Data may reflect geographic bias inherent to the specific cruise track in the Pacific Ocean.
