CLIVAR I09S 2004: Indian Ocean Carbon and Hydrographic Profiles from 2004-2005

From December 23, 2004, to February 17, 2005, this dataset contains discrete profile measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, dissolved oxygen, nutrients, and chlorofluorocarbons collected during the R/V Aurora Australis cruise AU0403 in the Indian Ocean. The data were collected by researchers Bronte Tilbrook and Stephen R. Rintoul of CSIRO as part of the CLIVAR Global Ocean Carbon and Repeat Hydrography Program. It aims to quantify changes in the storage and transport of heat, fresh water, and carbon dioxide.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and total alkalinity measurements.
• Analyzing water mass properties and circulation based on temperature, salinity, and dissolved oxygen profiles.
• Studying anthropogenic tracer distribution based on chlorofluorocarbon (CFC-11, CFC-12, CFC113) data.
• Investigating nutrient dynamics and biogeochemical cycles based on nutrient concentration measurements.

Strengths

• Data covers a specific, multi-month research cruise from 2004-12-23 to 2005-02 17.
• Includes multiple key oceanographic variables: DIC, alkalinity, temperature, salinity, oxygen, nutrients, and CFCs.
• Collected under the systematic CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single Indian Ocean transect.
