CLIVAR_SR03_2001: Southern Ocean Carbon and Hydrography Profiles from 2001

Discrete profile measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, dissolved oxygen, nutrients, and chlorofluorocarbons collected during the R/V Aurora Australis cruise AA0301 in the Southern Ocean from 2001-10-29 to 2001-12 13. These data were collected by researchers from CSIRO and NOAA PMEL as part of the CARINA and CLIVAR programs. The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program 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 changes in ocean circulation and water mass properties based on temperature, salinity, and chlorofluorocarbon profiles.
• Studying nutrient dynamics and biological productivity in the Southern Ocean based on nutrient concentration data.
• Calibrating and validating global ocean biogeochemical models using the suite of hydrographic and carbon system variables.

Strengths

• Data collected as part of the systematic, global CLIVAR Repeat Hydrography Program for quantifying change.
• Includes a multi-parameter suite of carbon, physical, and chemical measurements from a single research cruise.
• Cruise took place over a specific 46-day period from 2001-10-29 to 2001-12-13 in the Southern Ocean.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale statistical modeling.
