Chris Wilson/Australian Antarctic Division Adrian McCallum Lecturer in Science and Engineering, University of the Sunshine Coast Prime Minister Tony Abbott recently declared that he wanted to be known as the “infrastructure prime minister”. 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? Stations The British Antarctic Survey completed construction of their new Halley VI Station on the floating Brunt Ice Shelf, atop the Weddell Sea, East Antarctica in 2012. Because the Brunt Ice Shelf moves towards the sea at hundreds of metres per year, most of the old Halley stations now lie in the Southern Ocean. However, the award­winning new station, sitting on height­adjustable skis, can be towed inland every ten years or so, avoiding a watery grave. https://theconversation.com/why­the­infrastructure­pm­cant­give­antarctica­the­cold­shoulder­21059 1/4 26/02/2016 Why the 'infrastructure PM' can't give Antarctica the cold shoulder Halley VI Research Station British Antarctic Survey Fortunately, Australia’s stations do not exist in such a dynamic environment. Although Halley VI was delivered appreciably over budget, along with Belgium’s zero­emission Princess Elisabeth Station (unmanned and remotely managed during the winter), it provides an example of the lightweight, modular, “minimal footprint” complexes that are now preferred by Antarctic operators. This station further prompts the question: do we even need to man our stations over winter, caretaking at great expense of diesel fuel and dollars? Air and sea transport Australia lays claim to 42% of Antarctica, a vast wedge of the southern continent stretching east from beneath South Africa to underneath New Zealand, dissected only by a thin wedge beneath Australia, the French claim. Retaining strategically imperative access to this expanse means a double­barrelled intercontinental transport solution is necessary: a ship, for distributing heavy cargo to our solely coastal stations an air system, for rapid transfer of personnel and to locales far inland, away from the coast. The South Africans (among others) have recently acquired a new icebreaker, and with Antarctic sea ice reaching record extents, Australia must choose wisely. Australia’s icebreaker, the Aurora Australis, has served us well for more than 20 years, but repeated southern journeys take their toll. Icebreaker technology has since advanced and the vessel is nearing the end of its useful life. Australian icebreaker, Aurora Australis. dracophylla A vessel must be commissioned that serves capably as both an ice­capable logistical vessel and a marine science platform. This vessel will provide the backbone of our logistical framework for some time. Any air system would logically emanate from Hobart, Australia’s Antarctic “hub”. It should provide rapid access to one or all of our stations. But we have learned from our experience with the Wilkins Runway near Casey Station melting last year: any intercontinental air link should exist immediately next to a station and https://theconversation.com/why­the­infrastructure­pm­cant­give­antarctica­the­cold­shoulder­21059 2/4 26/02/2016 Why the 'infrastructure PM' can't give Antarctica the cold shoulder must be open throughout the summer operational season. A runway­surface/landing­gear configuration should be selected allowing ready use of Antarctica’s most plentiful construction material – snow – rather than relying on isolated patches of suitable ice. A suitable intracontinental system should also be chosen to provide efficient deep field access, ranging between stations and preferably interagency compatibility. Spare parts can be hard to come by down south. Overland transport The United States Antarctic Program recently revolutionised heavy ground transport by using “winterised” standard agricultural tractors running on rubber tracks. In all but the harshest conditions, rubber tracks are much better than metal­tracked vehicles (although I did specifically select metal tracks for Sir Ranulph Fiennes‘ aborted Coldest Journey winter crossing of Antarctica in 2013 because of the extreme conditions). Fuel is now typically stored in flexible rubber bladders (or “flubbers”) that along with containers or cabooses, can now be towed on low­friction polycarbonate sleds. ‘Flubbers’ are used for semi­permanent fuel storage and transporting fuel efficiently on low­friction polycarbonate sleds. Wikimedia Commons This system is fast and efficient and allows transportation of large quantities of fuel (still the lifeblood of current Antarctic stations) from coastal McMurdo Base to the US station at South Pole. Overland efficiencies approach nine times better than that attained with air transport. Many nations have now adopted this protocol and it is where Australia should head. Concurrent with any heavy­traverse capability, Australia should be thinking on how best to physically traverse our extensive inland reaches. Snowmobiles have typically been the vehicle of choice for personal snow transport, but they are inefficient and rely on petrol. An air­transportable, diesel­fuelled fleet would be more efficient and reduce logistical complexity. The British­led Moon­Regan Expedition recently completed a return journey across Antarctica (some 4,000 km) using a lightweight ski­equipped ‘“scout” vehicle in just over 20 days. https://theconversation.com/why­the­infrastructure­pm­cant­give­antarctica­the­cold­shoulder­21059 3/4 26/02/2016 Why the 'infrastructure PM' can't give Antarctica the cold shoulder Winston Wong Bio­Inspired Ice Vehicle of the Moon­Regan TransAntarctic Expedition. Moon­Regan TransAntarctic Expedition Perhaps variations on this concept using a poly base, Arctic Trucks or variations on the new Australian Tomcar should be considered as efficient long­range polar patrol vehicles. So who does what? Traditionally, Antarctica has been the preserve of governments with vast budgets, bludgeoning the wilderness into submission, much like the early Himalayan “siege” expeditions. But now, budgets are shrinking, environmentalism is (thankfully) key, and increasingly, private companies such as Antarctic Logistics and Expeditions and Antarctic Logistics Centre International offer logistical services both to and within Antarctica. All Antarctic national states should consider exactly what they need to “own” and how can increased sharing of infrastructural and logistical assets with government and private peers allow increased scientific productivity on reduced government budgets. Dr Press has a lot to consider. I look forward to his report.

  • 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.

We compare sea temperatures at a constant depth (10–20 m) at coastal localities both sides of the Polar Front (PF), around the Scotia-Arc, the West Antarctic Peninsula and at high oceanic latitudes (around the margins of East Antarctica). We assess the wider context of these values by investigating minimum and maximum temperatures and ranges throughout the Southern Ocean using remotely sensed SST data. Data to date show weekly, daily and hourly variation in shallow sea temperature can be one-third of total annual variability (in the summer) but can be very constant (in winter). From comparison across scales in time and space, the strong seasonal signal is the most striking feature of Antarctic shallow sea temperatures even at highest oceanic latitude sites. The winter sea temperatures at localities within the PF are similar (near freezing), but upper temperatures and thus the annual range vary predictably with latitude in a cline. This amounts to 0.2 1C annual range/100 km of latitude between 541S and 671S.

Continuous power supply for manned stations mainly relies on fuel. With the gradual increase in energy demand at the station and cost of fuel traffic from China to Zhongshan station in Antarctica, reducing fuel consumption and increasing green energy utilization are urgent problems. This research considers a standalone renewable energy system. The polar environments and renewable energy distribution of area of Zhongshan station are analyzed. The physical model, operation principle, and mathematical modeling of the proposed power system were designed. Low-temperature performance and state of charge (SOC) estimation method of the lead–acid battery were comprehensively tested and evaluated. A temperature control strategy was adopted to prevent the battery from low-temperature loss of the battery capacity. Energy management strategy of the power system was proposed by designing maximum power point tracking (MPPT) control strategies for wind turbine and PV array. The whole power system is broadly composed of a power generator (wind turbine and PV array), an uploading circuit, a three-phase rectifier bridge, an interleaved Buck circuit, a DC/DC conversion circuit, a switch circuit, a power supply circuit, an amplifier, a driver circuit, a voltage and current monitoring, a load, battery units and a control system.
