PACIFICA: CTD and Bottle Measurements from SHUMPU MARU Cruise

NCEI Accession 0115709 contains discrete sample and profile data collected during the PACIFICA_49SU19920225 cruise in the Philippine Sea. The dataset includes measurements of dissolved oxygen, hydrostatic pressure, nitrate, nitrite, salinity, water temperature, pH, and phosphate, collected using CTD and bottle instruments. These data were gathered by researchers from the Kobe Marine Observatory as part of the international PACIFICA project for synthesizing ocean interior carbon parameters.

Use Cases

• Analyzing vertical profiles of dissolved oxygen and salinity based on CTD data.
• Studying nutrient concentrations (nitrate, nitrite, phosphate) in relation to water temperature.
• Investigating carbon cycle parameters and pH variability in the Philippine Sea.
• Calibrating ocean biogeochemical models with discrete bottle sample measurements.

Strengths

• Data originates from a defined international research project (PACIFICA) supported by PICES.
• Includes a specific set of eight measured parameters relevant to ocean carbon and nutrient studies.
• Collection methodology is documented, specifying CTD and bottle instruments.

Limitations

• Exact column names, row count, and dataset size are unknown across all platforms.
• Metadata completeness is low; license, author, and organization details are unspecified.
• The temporal coverage is limited to a single five-day cruise in February 1992.
