The joint TOT-Cal / CryoVExANT2011 project contributes to the validation of the CryoSat-2 altimetry mission through investigations of a key portion of the East Antarctic ice sheet near Australia’s Casey Station. Spanning parts of Law Dome and the Totten Glacier…

The sub-Antarctic region between 45-60°S is primarily ocean. However, there are a few small isolated islands, most of which are currently facing the combined pressures of climate change and introduced species.
The sub-Antarctic region between 45-60 °S is primarily ocean. However, there are a few small isolated islands, most of which are currently facing the combined pressures of climate change and introduced species.
Sub-Antarctic islands are the only landmasses between Antarctica and South America, Africa and Australia where terrestrial climate and ecosystem records are available, making them crucial locations for linking southern mid and high latitude regions. However…
A consequence of the wave-number rich tidal activity that has been observed in the southern polar MLT is that the horizontal flux of horizontal momentum (u'v') is likely to be non-zero. This quantity is affected by the phase angle between the zonal and meridional wind perturbations.
