1993-04-04 to 1993 05-09 data collection includes dissolved inorganic carbon, dissolved oxygen, salinity, water temperature, and nutrient concentrations from the Indian, South Pacific, and Southern Oceans. The dataset was collected by researchers Bronte Tilbrook and Stephen R. Rintoul of the Commonwealth Scientific and Industrial Research Organization from the vessel AURORA AUSTRALIS. It is part of the World Ocean Circulation Experiment (WOCE) Hydrographic Program, which aimed to understand the ocean's role in climate.
Use Cases
- Modeling ocean carbon uptake by analyzing dissolved_inorganic_carbon against water_temperature and salinity.
- Studying water mass properties and circulation using potential_temperature and hydrostatic_pressure profiles.
- Investigating nutrient limitations in polar regions by correlating phosphate and silicate concentrations with location.
- Calibrating biogeochemical models with concurrent measurements of dissolved_oxygen and nitrate+nitrite_content.
Strengths
- Data collected as part of the standardized World Ocean Circulation Experiment (WOCE) program, ensuring consistent methodology.
- Includes multiple key oceanographic variables (DIC, nutrients, temperature, salinity) measured concurrently from discrete samples.
Limitations
- Limited temporal coverage to a single cruise over approximately one month in 1993.
- Geographic scope is restricted to the specific cruise track in the Southern Hemisphere oceans.
- Sample size (number of stations or rows) for this specific accession is not provided.
