A holistic review is given of the Southern Ocean dynamic system, in the context of the crucial role it plays in the global climate and the profound changes it is experiencing. The review focuses on connections between different components of the Southern Ocean dynamic system…
Societal adaptation to rising sea levels requires robust projections of the Antarctic Ice Sheet's retreat, particularly due to ocean-driven basal melting of its fringing ice shelves.
Ocean-driven basal melt can thin and weaken ice shelves, reducing buttressing and causing sea level rise. However, the processes driving melt in ice shelf cavities are challenging to observe. Here we report float observations spanning the ocean cavity beneath Shackleton Ice Shelf.
One of the principal factors influencing mass loss and sea level contribution from … the Antarctic Ice Sheet currently and in future centuries is the melting of ice … shelves by the ocean. These floating extensions of the ice sheet buttress against … ice-sheet movement…
Vincennes Bay is a region of East Antarctica vulnerable to sub-ice shelf basal melting from warm ocean water intrusions. The sub-ice shelf bathymetry in this region is largely unknown, despite its importance for ocean dynamics within ice shelf cavities and associated sub-ice shelf basal melting.
The present-day state and future of the Antarctic Ice Sheet depend on the rate at which the ocean melts its fringing ice shelves. Ocean heat must cross many physical and dynamical barriers to melt ice shelves, with the last of these being the ice-ocean boundary layer.
The 2017 ozone hole … developed in the first week of August and rose sharply to reach a peak size … in early September, this was then followed by a significant warming event … which reduced the overall areal extent of the ozone hole considerably.
Surface and subsurface sediments from a helipad in Bunger Hills were collected ten years after accidental contamination with a small quantity (probably less than 10 litres) of petroleum products.
Climatological monthly upper-ocean temperature anomalies from the annual mean in the subtropical southwest … Pacific Ocean show a characteristic out-of-phase relationship between the mixed layer and the underlying water.
