Less than one year after the spectacular calving of the Mertz Glacier tongue, scientists were collecting the first ever images of the seafloor where the glacier tongue once sat.

Frank Stillwell was a member of Douglas Mawson's 1911-1914 expedition to Cape Denison, Commonwealth Bay, Antarctica. His 1912 diary is being edited for publication. The editor has asked for a text box to be included in the publication that describes aspects of the geomagnetism activities that formed part of the expedition's scientific program.

The sidebar article will accompany a longer article by Lt Peter Waring of the Royal Australian Navy survey team that conducted a multibeam survey in Casey Harbour during season 2013-14

Life in icy waters: A geoscience perspective of life on the Antarctic seafloor

Dense hydrocoral-sponge communities have been identified on the upper continental slope of George V Land, East Antarctica and declared Vulnerable Marine Ecosystems. Analysis of physical and biological datasets collected during the 2007/08 CEAMARC survey identified that the richest communities are found in the heads of canyons which receive Antarctic Bottom Water formed on the George V shelf, and the canyons harbouring rich benthos are also those that cut the shelf break. This led to several hypotheses regarding their distribution and three main factors were identified. These hypotheses were tested during a recent marine science voyage in January 2011 to the same region. Initial analysis of the new data supports the hypotheses regarding the physical controls on hydrocoral-sponge community distribution.

Geoscience Australia distributes a range of Antarctica maps and images at various scales and currency, on behalf of Australian Antarctic Division. These products are very diverse and include topographic maps and satellite images, ranging from landscape specific (1:1,000 scale) to regional (1:20,000,000) scale.

The Cenozoic glacial history of East Antarctica is recorded in part by the stratigraphy of the Prydz Bay-Lambert Graben region. The glacigene strata and associated erosion surfaces record at least 10 intervals of glacial advance (with accompanying erosion and sediment compaction), and more than 17 intervals of glacial retreat (enabling open marine deposition in Prydz Bay and the Lambert Graben). The number of glacial advances and retreats is considerably less than would be expected from Milankovitch frequencies due to the incomplete stratigraphic record. Large advances of the Lambert Glacier caused progradation of the continental shelf edge. At times of extreme glacial retreat, marine conditions reached > 450 km inland from the modern ice shelf edge. This review presents a partial reconstruction of Cenozoic glacial extent within Prydz Bay and the Lambert Graben that can be compared to eustatic sea-level records from the southern Australian continental margin.

The stability of floating ice shelves is an important indicator of ocean circulation and ice-shelf mass balance. A sub-ice -shelf sediment core collected during the Austral summer of 2000-2001 from site AM02 on the Amery Ice Shelf, East Antarctica, contains a full and continuous record of glacial retreat.
