The Southern Ocean cruise AA9706 collected discrete profile measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, dissolved oxygen, nutrients, and delta C13 from 1998-02-28 to 1998-04-01. These data were collected by researchers from Antarctic Climate & Ecosystems CRC, CSIRO, and UNSW as part of the World Ocean Circulation Experiment (WOCE) Hydrographic Program. The final WOCE collection covers approximately 23,000 stations from 94 cruises between 1990 and 1998.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing nutrient distributions and their relationship with ocean circulation patterns.
- Studying isotopic carbon (delta C13) variations for biogeochemical process tracing.
- Calibrating and validating ocean biogeochemical models using discrete profile data.
Strengths
- Data is part of the major World Ocean Circulation Experiment (WOCE) program, a standardized global effort.
- Cruise data includes multiple key ocean chemistry variables (DIC, alkalinity, oxygen, nutrients, delta C13).
- The broader WOCE collection covers approximately 23,000 stations from 94 cruises, indicating a substantial program.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1998-04-01; freshness should be verified for contemporary applications.
- Row count for this specific accession is unknown, which may limit suitability assessment.
