Profile discrete measurements of temperature, salinity, oxygen, nutrients, and dissolved inorganic carbon were collected during the RSV Aurora Australis cruise AU9407. The data covers the WOCE Repeat Hydrography Section SR03 in the Southern Ocean between Tasmania and Antarctica. The National Oceanic and Atmospheric Administration's National Centers for Environmental Information (NOAA NCEI) provides this data from a two-month expedition in early 1994.
Use Cases
- Analyze dissolved inorganic carbon concentrations against temperature and salinity profiles to study ocean carbon uptake.
- Map nutrient distributions (e.g., phosphate, nitrate) along the meridional section to understand Southern Ocean biogeochemistry.
- Correlate oxygen measurements with hydrographic data to assess water mass ventilation and age.
- Use the precise latitude/longitude and time data to create a spatial-temporal map of chemical properties across the Princess Elizabeth Trough.
Strengths
- Data collected along the established WOCE SR03 repeat hydrography section, enabling climate trend analysis.
- Includes multiple core oceanographic variables (temperature, salinity, oxygen, nutrients, DIC) from a single cruise.
Limitations
- Data is from a single two-month cruise in 1994, providing only a temporal snapshot.
- Spatial coverage is limited to specific transects in the Southern Ocean between ~82-86°E and the SR03 line.
