However, other than a preliminary attempt to reconstruct Antarctic topography at the Eocene–Oligocene boundary, the long-term evolution of Antarctica's subglacial topography throughout its glacial history has not previously been quantified. Here, we derive new reconstructions of Antarctic topography for four key time slices in Antarctica's climate andglacial history: the Eocene–Oligocene boundary (ca. 34 Ma), the Oligocene–Miocene boundary (ca. 23 Ma), the mid-Miocene climate transition (ca. 14 Ma), and the mid- Pliocene warm period (ca. 3.5 Ma). To reconstruct past topography, we consider a series of processes including ice sheet loading, volcanism, thermal subsidence, horizontal plate motion, erosion, sedimentation and flexural isostatic adjustment, and validate our models where possible using onshore and offshore geological constraints. Our reconstructions show that the land area of Antarctica situated above sea level was ~25% larger at the Eocene–Oligocene boundary than at the present-day. -

Foreign Affairs, Defence and Trade Committee Department of the Senate PO Box 6100 Parliament House Canberra ACT 2600 Dear Committee Thank you for the opportunity to submit a response to the Foreign Affairs, Defence and Trade References Committee on the inquiry into Australia’s future activities and responsibilities in the Southern Ocean and Antarctic waters. The Australian Maritime Safety Authority (AMSA) is a statutory authority established under the Australian Maritime Safety Authority Act 1990 with the primary role to minimise the risk of shipping incidents and pollution in Australian waters, through ship safety and environment protection regulation and services, and maximise people saved from maritime and aviation incidents through search and rescue coordination. AMSA’s submission is structured around the following terms of reference for the inquiry: b. cooperation with international partners on management and research under international treaties and agreements; c. appropriate resourcing in the Southern Ocean and Antarctic territory for research and governance; and d. any other related matters. - 2 The submission is focussed on three principal areas of interest to AMSA – the International Maritime Organization Polar Code, pollution response initiatives and Search and Rescue. Yours sincerely MICK KINLEY 27 June 2014 Encls.

BAS Science Summaries 2018-2019 Antarctic Field Season
BAS Science Summaries 2018-2019 Antarctic field season BAS Science Summaries 2018-2019 Antarctic field season Introduction This booklet contains the project summaries of field, station and ship-based science that the British Antarctic Survey (BAS) is supporting during the forthcoming 2018/19 Antarctic field season. I think it demonstrates once again the breadth and scale of the science that BAS undertakes and supports. For more detailed information about individual projects please contact the Principal Investigators. There is no doubt that 2018/19 is another challenging field season, and it’s one in which the key focus is on the West Antarctic Ice Sheet (WAIS) and how this has changed in the past, and may change in the future. Three projects, all logistically big in their scale, are BEAMISH, Thwaites and WACSWAIN. They will advance our understanding of the fragility and complexity of the WAIS and how the ice sheets are responding to environmental change, and contributing to global sea-level rise. Please note that only the PIs and field personnel have been listed in this document. PIs appear in capitals and in brackets if they are not present on site, and Field Guides are indicated with an asterisk. Non-BAS personnel are shown in blue. A full list of non-BAS personnel and their affiliated organisations is shown in the Appendix. My thanks to the authors for their contributions, to MAGIC for the field sites map, and to Elaine Fitzcharles and Ali Massey for collating all the material together. Thanks also to members of the Communications Team for the editing and production of this handy summary. -
