From January 4 to February 6, 2011, discrete measurements were collected during the R/V Aurora Australis cruise SR03_2011 in the Southern Ocean. The data include CTD temperature, salinity, dissolved oxygen, nutrients, dissolved inorganic carbon, and total alkalinity. It was collected by Stephen R. Rintoul of CSIRO and Mark Rosenberg of UTAS as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
Use Cases
- Modeling ocean carbon sequestration based on dissolved inorganic carbon and total alkalinity measurements.
- Analyzing changes in ocean heat content based on CTD temperature and salinity profiles.
- Studying marine biogeochemical cycles based on nutrient and dissolved oxygen data.
- Quantifying changes in Southern Ocean water properties for climate studies based on repeat hydrography.
Strengths
- Data is part of a systematic global re-occupation program (CLIVAR) designed for quantifying change.
- Includes multiple core oceanographic parameters (temperature, salinity, oxygen, nutrients, carbon, alkalinity).
- Cruise has specific identifiers (EXPOCODE 09AR20110104, AU1121) for traceability.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last metadata update was 2026-03-05.
