August-September 1996 oceanographic measurements from 71 CTD vertical profile stations and over 1500 water samples collected along the WOCE SR3 section between Tasmania and Antarctica. The dataset includes profiles of temperature, salinity, dissolved oxygen, nutrients, and biological parameters. Data were collected by the Australian Antarctic Data Centre during the AU9601 cruise.
Use Cases
- Analyze vertical profiles of temperature and salinity (sigma-T) to identify water masses and mixing processes in the Southern Ocean.
- Model relationships between dissolved inorganic carbon, alkalinity, and nutrients (phosphate, nitrate+nitrite, silicate) to study the ocean carbon cycle.
- Correlate fluorescence and photosynthetically active radiation measurements with primary productivity data to assess phytoplankton activity.
- Map geopotential anomaly against station positions to calculate geostrophic currents along the cruise track.
- Investigate the relationship between dissolved oxygen concentration and biological parameters across different depths and stations.
Strengths
- 71 CTD vertical profile stations, most extending to near the sea floor.
- Over 1500 discrete water samples analyzed for a suite of chemical and biological parameters.
Limitations
- Data is from a single cruise in 1996, offering only a snapshot in time.
- Spatial coverage is limited to the specific WOCE SR3 transect between Tasmania and Antarctica.
- Sample data and exact row/column counts are unavailable for assessing granularity.
