January 1994 measurements of temperature, salinity, oxygen, nutrients, and dissolved inorganic carbon collected from discrete profile samples during the RSV Aurora Australis cruise AU9407. The cruise followed the WOCE Repeat Hydrography Section SR03 between Tasmania and Antarctica, and a northward section crossing the Princess Elizabeth Trough. The dataset is provided by the National Oceanic and Atmospheric Administration.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon measurements.
- Analyzing water mass structure based on temperature and salinity profiles.
- Studying nutrient cycling in the Southern Ocean based on nitrate and phosphate data.
- Investigating oxygen distribution and its relation to biological processes.
- Calibrating satellite-derived oceanographic data with in-situ profile measurements.
Strengths
- Includes multiple core oceanographic variables: temperature, salinity, oxygen, nutrients, and dissolved inorganic carbon.
- Data collected along a defined, repeat hydrography section (WOCE SR03) for comparative studies.
- Cruise covered a specific temporal window (January 1994) and geographic area (Southern Ocean).
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/temporal bias inherent to a single cruise.
