Meridional winds over the seasonal ice zone of the Antarctic have undergone changes and likely contributed to sea ice extent variability in recent decades. In this study, using observations and an eddy-resolving channel model of the Antarctic seasonal ice zone…
As the climate warms, the grounded ice sheet and floating ice shelves surrounding Antarctica are melting and releasing additional freshwater into the Southern Ocean. Nonetheless…
The additional water from the Antarctic ice sheet and ice shelves due to climate-induced melt can impact ocean circulation and global climate. However, the major processes driving melt are not adequately represented in Coupled Model Intercomparison Project phase 6 (CMIP6) models. Here…
This presentation introduces a recently awarded Australian Antarctic Science (AAS) project as part of the research theme 1 'Climate Processes and Change'. This project utilises the technique of Global Positioning System (GPS) Radio Occultation (RO)…
the glaciation and isolation of the Antarctic continent completed by ~10 million years ago, and not by the sequential break-up of Gondwana (completed by ~32 million years ago). More recently…
1. Microbial plankton dynamics in an ultra-oligotrophic epishelf lake (Beaver Lake, Antarctica) were investigated over an austral summer (December 2002 to January 2003). The aim was to characterise carbon cycling in an environmentally extreme lake. 2.
