Discrete water samples and CTD profiles from a 1997 research cruise provide measurements of dissolved inorganic carbon, alkalinity, nutrients, and chlorofluorocarbons. The data were collected by researchers from Hawaii Pacific University and the University of Washington aboard the R/V Thomas G. Thompson. This cruise was part of the World Ocean Circulation Experiment, which aimed to collect approximately 23,000 stations globally between 1990 and 1998.
Use Cases
- Calculate ocean carbon uptake using DISSOLVED INORGANIC CARBON and ALKALINITY measurements paired with SALINITY and WATER TEMPERATURE.
- Study ocean ventilation rates and water mass age by analyzing CHLOROFLUOROCARBON-11 and CHLOROFLUOROCARBON-12 concentrations against HYDROSTATIC PRESSURE profiles.
- Model nutrient limitations in marine ecosystems by correlating NITRATE, PHOSPHATE, and SILICATE levels with DISSOLVED OXYGEN and Potential temperature (theta).
- Calibrate or validate regional ocean carbon models using the high-resolution vertical profile data for DISSOLVED INORGANIC CARBON and ALKALINITY.
Strengths
- Data collected as part of the standardized global World Ocean Circulation Experiment (WOCE) program, ensuring consistent methodology.
- Includes multiple core variables for carbon system calculation (DIC, Alkalinity) alongside supporting physical and nutrient data.
Limitations
- Dataset is limited to a single 11-day cruise in the North Pacific Ocean in November 1997, providing only a regional and seasonal snapshot.
- Sample size and row count are unknown, but discrete bottle data typically represent a limited number of depths per station.
