AUSTRALIAN ANTARCTIC MAGAZINE ISSUE 29 2015 AUSTRALIAN ANTARCTIC MAGAZINE ISSUE 29 2015 The Australian Antarctic Division, a Division of the Department of the Environment, leads Australia’s Antarctic program and seeks to advance Australia’s Antarctic interests in pursuit of its vision of having ‘Antarctica valued, protected and understood’. It does this by managing Australian government activity in Antarctica, providing transport and logistic support to Australia’s Antarctic research program, maintaining four permanent Australian research stations, and conducting scientific research SCIENCE programs both on land and in the Southern Ocean. 12 Measuring algae in the fast ice Australia’s Antarctic national interests are to: • Preserve our sovereignty over the Australian Antarctic ICEBREAKER HISTORY Territory, including our sovereign rights over the 16 New icebreaker plans unveiled 24 Two-wheeled Antarctic adventures adjacent offshore areas. • Take advantage of the special opportunities Antarctica offers for scientific research. • Protect the Antarctic environment, having regard to its special qualities and effects on our region. • Maintain Antarctica’s freedom from strategic and/or political confrontation. • Be informed about and able to influence developments in a region geographically proximate to Australia. • Derive any reasonable economic benefits from living and non-living resources of the Antarctic (excluding deriving such benefits from mining and oil drilling). Australian Antarctic Magazine seeks to inform the Australian and international Antarctic community about the activities of the Australian Antarctic program.

The Partnership aims to consolidate Tasmania’s place as a global leader in Antarctic and Southern Ocean science and get more scientists on the ice. Australia’s Antarctic future In August I was privileged to take on the role of Director of the Australian Antarctic Division, at one of the most exciting times in Australia’s Antarctic history. Top of my ‘to do’ list is continuing the good work started by our previous Director, Dr Tony Fleming, to support the delivery of an Australian Antarctic strategy and, as part of that strategy, replace our ageing icebreaker ship, Aurora Australis, with a new research and resupply vessel.

But what of Australia’s iciest infrastructure – that located in Antarctica? A 20­year strategic plan for Australia’s Antarctic future was recently commissioned by the federal government, but it will be another six months before Tony Press, ex­director of the Australian Antarctic Division, reveals his “blueprint”. So what is best practice when it comes to polar infrastructure, and where should Australia be heading to maintain our status as a leader in Antarctic science and operations?

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 Prince Charles Mountains have been subject to extensive geological and geophysical inves- tigations by former Soviet,Russian and Australian scientists from the early 1970s. In this paper we sum- marise, and review available geological and isotopic data, and report results of new isotopic studies (Sm- Nd, Pb-Pb, and U-Pb SHRIMP analyses); field geological data obtained during the PCMEGA 2002/2003 are utilised. The structure of the region is described in terms of four tectonic terranes. Those include Ar- chaean Ruker, Palaeoproterozoic Lambert, Mesoproterozoic Fisher, and Meso- to Neoproterozoic Beaver Terranes. Pan-African activities (granite emplacement and probably tectonics) in the Lambert Terrane are reported. We present a summary of the composition of these terranes, discuss their origin and relations- hips.

This unit records clastic sedimentation in fresh−water depositional system during the early stages of development of the Lambert Graben, a major structural valley surrounded by crystalline highlands in the southern part of Gondwana. It contains common siderite precipitated through early diagenetic processes in the swamp, stagnant water, and stream−flow environments. There are two types of siderite in the Panorama Point Beds: (1) disseminated cement that occurs throughout the sedimentary suc− cession; and (2) concretions that occur at recurrent horizons in fine−grained sediments. The cement is composed of Fe−depleted siderite (less than 90 mol % FeCO3) with an elevated con− d13 tent of magnesium, and trace and rare earth elements. It has negative CVPDB values (−4.5 to −1.5‰). The concretions are dominated by Fe−rich siderite (more than 90 mol % FeCO3), with d13 positive CVPDB values (+1 to +8‰).

These erratics were derived from a suite of glaciogene strata hidden beneath the Ant- arctic Ice Sheet in the Lambert glacier drainage system, and thus provide a record of Cenozoic paleoenvironmental conditions and fossil biotas that are so far unknown from outcrops and drill cores in this region. By microfossil analysis, sparse Neogene spores and pollen grains are revealed, including: Toroisporis (Lygodiaceae), Granulatisporites (Pteridaceae?), Osmunda (Osmundaceae), Polypodiaceae, Magnastriatites (Parkeriaceae), Deltoidospora, Araucariaceae, Taxodiaceae, Podocarpus (Podocarpaceae), Dacrydium (Podocarpaceae), Pinus (Pinaceae), Keteleeria (Pinaceae), Picea (Pinaceae), Tsuga (Pinaceae), Chenopodiaceae,

    Management Plan for Antarctic Specially Protected Area No

    Measure 9 (2011) Annex Management Plan for Antarctic Specially Protected Area No. 167 Hawker Island, Princess Elizabeth Land Introduction Hawker Island (68°38’S, 77°51’E, Map A) is located 7 km south-west from Davis station off the Vestfold Hills on the Ingrid Christensen Coast, Princess Elizabeth Land, East Antarctica. The island was designated as Antarctic Specially Protected Area (ASPA) No. 167 under Measure 1 (2006), following a proposal by Australia, primarily to protect the southernmost breeding colony of southern giant petrels (Macronectes giganteus) (Map B). The Area is one of only four known breeding locations for southern giant petrels on the coast of East Antarctica, all of which have been designated as ASPAs: ASPA 102, Rookery Islands, Holme Bay, Mac.Robertson Land (67º36’S, 62º53’E) – near Mawson Station; ASPA 160, Frazier Islands, Wilkes Land (66°13’S, 110°11’E) – near Casey station; and ASPA 120, Pointe Géologie, Terre Adélie (66º40’S, 140º01’E) – near Dumont d’Urville. Hawker Island also supports breeding colonies of Adélie penguins (Pygocelis adeliae), south polar skuas (Catharacta maccormicki), Cape petrels (Daption capense) and occasionally Weddell seals (Leptonychotes weddellii). 1. Description of values to be protected The total population of southern giant petrels in East Antarctica represents less than 1% of the global breeding population. It is currently estimated at approximately 300 pairs, comprising approximately 45 pairs on Hawker Island (2010), 2-4 pairs on Giganteus Island (Rookery Islands group) (2007), approximately 250 pairs on the Frazier Islands (2001) and 8-9 pairs at Pointe Géologie (2005). Southern giant petrels also breed on other islands in the southern Indian and Atlantic Oceans and at the Antarctic Peninsula.
