Australian Antarctic Magazine — Issue 31: December 2016 AUSTRALIAN ANTARCTIC MAGAZINE ISSUE 31 2016 The Australian Antarctic Division, a Division of the Department of the Environment and Energy, 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 programs both on land and in the Southern Ocean. Australia’s Antarctic national interests are to: ICEBREAKER • Preserve our sovereignty over the Australian Antarctic Territory, including our sovereign rights 2 Future-proofing icebreaker science over the adjacent offshore areas. • Take advantage of the special opportunities SCIENCE HISTORY Antarctica offers for scientific research. 20 Mobile diatoms flourish in acid ocean 25 In from the cold: unlocking the secrets of Antarctic field notebooks • 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 is produced twice a year (June and December). Australian Antarctic Magazine seeks to inform the Australian and international Antarctic community about the activities of the Australian Antarctic program.

As this magazine went to press I attended the annual International Whaling Commission meeting in my new role as Australia’s Commissioner to the IWC. Australia was instrumental in establishing the moratorium on commercial whaling in 1986, and as Commissioner I will continue to advocate for a permanent end to all forms of commercial whaling and so-called scientific whaling. Australian researchers, many coordinated by the Australian Marine Mammal Centre at the Australian Antarctic Division, have demonstrated that all information necessary for the management and conservation of whales can be obtained through non-lethal methods. Australia, alongside France, also played a key role in the development and signing of the Madrid Protocol, which bans mining in Antarctica indefinitely and designates Antarctica as a natural reserve, devoted to peace and science. The Protocol has been a highly successful agreement, providing a framework for advancing environmental protection and accommodating emerging environmental challenges.

  • Amanda Bay, Ingrid Christensen Coast, Princess Elizabeth Land, East Antarctica
    MEASURE 3 - ANNEX Management Plan for Antarctic Specially Protected Area No 169 AMANDA BAY, INGRID CHRISTENSEN COAST, PRINCESS ELIZABETH LAND, EAST ANTARCTICA Introduction Amanda Bay is located on the Ingrid Christensen Coast of Princess Elizabeth Land, East Antarctica at 69°15' S, 76°49’59.9" E. (Map A). The Antarctic Specially Protected Area (ASPA) is designated to protect the breeding colony of several thousand pairs of emperor penguins annually resident in the south-west corner of Amanda Bay, while providing for continued collection of valuable long- term research and monitoring data and comparative studies with colonies elsewhere in East Antarctica. Only two other emperor penguin colonies along the extensive East Antarctic coastline are protected within ASPAs (ASPA 120, Point Géologie Archipelago and ASPA 167 Haswell Island). Amanda Bay is more easily accessed, from vessels or by vehicle from research stations in the Larsemann Hills and Vestfold Hills, than many other emperor penguin colonies in East Antarctica. This accessibility is advantageous for research purposes, but also creates the potential for human disturbance of the birds. The Antarctic coastline in the vicinity of Amanda Bay was first sighted and named the Ingrid Christensen Coast by Captain Mikkelsen in command of the Norwegian ship Thorshavn on 20 February 1935. Oblique aerial photographs of the coastline were taken by the Lars Christensen expedition in 1937 and by the US Operation Highjump in 1947 for reconnaissance purposes. In the 1954/55 summer, the Australian National Antarctic Research Expedition (ANARE) on the Kista Dan explored the waters of Prydz Bay, and the first recorded landing in the area was made by a sledging party led by Dr.

Tides influence basal melting of individual Antarctic ice shelves, but their net impact on Antarctic-wide ice-ocean interaction has yet to be constrained. Here we quantify the impact of tides on ice shelf melting and the continental shelf seas 5 by means of a 4 km resolution circum-Antarctic ocean model. Activating tides in the model increases the total basal mass loss by 57 Gt/yr (4 %), while decreasing continental shelf temperatures by 0.04 ◦C, indicating a slightly more efficient conversion of ocean heat into ice shelf melting. Regional variations can be larger, with melt rate modulations exceeding 500 % and temperatures changing by more than 0.5 ◦C, highlighting the importance of capturing tides for robust modelling of glacier systems and coastal oceans. Tide-induced changes around the Antarctic Peninsula have a dipolar distribution with decreased 10 ocean temperatures and reduced melting towards the Bellingshausen Sea and warming along the continental shelf break on the Weddell Sea side. This warming extends under the Ronne Ice Shelf, which also features one of the highest increases in area-averaged basal melting (150 %) when tides are included.

Fossil analysis of a 47 cm long sediment core revealed a rich modern fauna dominated by filter feeders (sponges and bryozoans). The down-core assemblage indicated a succession in the colonisation of this site. The lower portion of the core (before ~9600 yr BP) was completely devoid of preserved fauna. The first colonisers (at ~10 200 yr BP) were mobile benthic organisms. Their occurrence was matched by the first appearance of planktonic taxa, indicating a retreat of the ice shelf following the last glaciation to within sufficient distance to advect planktonic particles via bottom currents. The benthic infauna and filter feeders emerged during the peak abundance of the planktonic organisms, indicating their dependence on the food supply sourced from the open shelf waters of Prydz Bay. Understanding patterns of species succession in this environment has important implications for determining the potential significance of future ice shelf collapse.

The present study has been conducted on Larsemann Hills, Prydz Bay, East Antarctica. The two LISS-IV images (5.8 m spatial resolution) acquired specifically 384 days apart (December 31, 2013 and January 19, 2015) were utilized to study the significant changes that have occurred in icebergs during this short epoch. A total of 369 common icebergs present in both images were identified for analysing the changes in their dimensions because of surface melting. All of these icebergs were found to have lost mass because of surface melting and ocean forced base melting; therefore, they have reduced in dimension depicted by 12.51% lapse in terms of surface area.
