May to September 1999 data collection includes dissolved inorganic carbon, pH, alkalinity, temperature, salinity, and other chemical and physical variables. Measurements were taken from the KAIYO-MARU and MIRAI vessels in the North Pacific Ocean using CTD and bottle instruments. The data were collected by researchers from the National Research Institute of Fisheries Science and Tokai University as part of the WOCE_P01_SAGE_1_Revisit cruise.
Use Cases
- Modeling ocean acidification by analyzing relationships between DISSOLVED INORGANIC CARBON (DIC), pH, and TOTAL ALKALINITY (TA).
- Studying water mass circulation using tracers like CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), and SULFUR HEXAFLUORIDE (SF6).
- Investigating biological productivity by correlating CHLOROPHYLL A with nutrient levels like NITRATE, PHOSPHATE, and SILICATE.
- Analyzing thermohaline structure using SALINITY, WATER TEMPERATURE, and Potential temperature (theta) profiles.
- Calibrating carbonate system models with direct measurements of DELTA CARBON-13 and DELTA CARBON-14.
Strengths
- Includes 20+ distinct chemical, biological, and physical variables per observation.
- Data collected as part of the standardized World Ocean Circulation Experiment (WOCE) Hydrographic Program.
Limitations
- Temporal coverage is limited to a single 4-month period in 1999.
- Spatial coverage is restricted to specific cruise tracks in the North Pacific Ocean.
- Sample size (number of stations/rows) for this specific accession is unknown.
