Major gaps exist in our understanding of the pathways between the generation and the breaking of internal waves in the Southern Ocean. This has important implications for the distribution of internal wave-driven turbulent mixing, for the sensitivity of ocean mixing rates, and for the representation of ocean mixing in numerical models.

High resolution ocean modelling has found the world’s strongest ocean currents, which play key roles in fisheries and ocean ecosystems, will experience more intense marine heatwaves than the global average over coming decades.
CLEX researchers used real-world observations with satellite observations to calculate the quantity of nutrients carried into the Subantarctic Zone by mesoscale eddies. They found these eddies carried high nitrate and low silicate waters into the Subantarctic Zone.
CLEX researchers investigate the physics of the Antarctic Circumpolar Current to understand why increased wind stress doesn't lead to a more powerful current. It turns out the ocean floor plays a key role.
UNSW10: Air-sea heat exchange and upper ocean properties across the Polar Front in the Southern OceanJuly 19, 2019 10:00 am Comments Off on UNSW10: Air-sea heat exchange and upper ocean properties across the Polar Front in the Southern Ocean
This project will quantify the impact of the front on air-sea exchange of heat and characterise how air-sea exchange and upper ocean properties change across the front.
CLEX researchers propose that 21% of the heat carried across the Subantarctic Front south of Tasmania is achieved by long-lived, cold-core eddies entering the Subantarctic Zone.
It has been a very active time for the Climate Variability and Teleconnections Research Program in terms of research and engagement activities right across the team, including two expeditions - one drilling coral cores in the tropics and another going south to the Antarctic Circumpolar Current.
The RV Investigator returned to Hobart after a 32-day voyage to map a meander of the Antarctic Circumpolar Current (ACC) Polar Front. Onboard were 11 CLEX students and postdocs; three international students; a film maker and visual artist; and collaborators from CSIRO, Antarctic Climate and Ecosystems Cooperative Research Centre, and Woods Hole Oceanographic Institution.
