Prof Nathan Bindoff (UTAS) | RV Investigator research voyage in2018_v05, titled “How does a standing meander southeast of Tasmania brake the Antarctic Circumpolar Current?" The planet’s largest current, the Antarctic Circumpolar Current (ACC) distributes heat, freshwater and carbon-dioxide among the major oceans. It is a central element of the global overturning circulation that has allowed the ocean to absorb 93% of global warming. Despite Southern Ocean winds increasing for the last 2 decades, the ACC strength has not changed. A major puzzle in understanding climate variability is how the ACC responds to the additional wind energy. We will address the societally-important need to understand how the ACC and Southern Ocean’s capacity to absorb heat and carbon-dioxide will respond to climate variability and change. We will combine a full-depth CTD/LADCP and bathymetric survey of the full meander, with targeted, rapid underway sampling of smaller-scale variability using the Triaxus towed CTD, a VMP-2000 microstructure profiler and underway instruments. Multi-beam data will be important for interpreting the survey data. Water samples will be analysed for nutrients, chlorophyll and particulate organic carbon (POC). Incubation experiments will be conducted to observe phytoplankton productivity under varying physical and chemical conditions. Objectives 1. Deployment of a fleet of EM-APEX profiling floats. 2. Deployment of a tall mooring at the crest of a meander in the Polar Front of the Antarctic Circumpolar Current. 3. Full-depth hydrographic survey of the physics and biogeochemistry of the targeted ACC meander, conducting transects across the front. This will include CTD/LADCP profiles, water sample analysis, VMP-2000 microstructure profiles, bathymetry and underway instruments. 4. Triaxus transects. These will include transects across and along the front and transects around the mooring. |
