The Heard Island and McDonald Islands Territory is located in the southern Indian Ocean, the associated Marine Reserve covers approximately 71,200 square kilometres. • Australia has deep and enduring national interests in Antarctica and the Southern Ocean. Improved communications to the Australian Antarctic Territory would support these interests and significantly enhance Australia’s scientific and operational capability in the region. • An investment in undersea fibre cable and satellite data capability has the potential to address the constraints presently faced by the Australian Antarctic Program in using communications technologies for science and operations. It also has the potential to transform Australia’s Antarctic science program capabilities and ensure that these are future-proofed. • Strong communications capability is in alignment with the whole-of-Government Australian Antarctic Strategy and 20 Year Action Plan, and is a necessary precursor to secure the future of Hobart and Tasmania as a modern and functional Antarctic Gateway, supporting the needs of expeditioners, and the requirements of modern infrastructure and programs. Introduction The Australian Antarctic Division welcomes this opportunity to contribute to the Committee’s inquiry into the availability and access to enabling communications infrastructure in Australia’s external territories. The Australian Antarctic Division is responsible for the administration of the Australian Antarctic Territory and Territory of Heard Island and McDonald Islands, and leads, coordinates and delivers the Australian Antarctic Program. The Australian Antarctic Territory is a sovereign part of Australia. It is administered as such, and is subject to Australia’s legal regime. The Australian Antarctic Territory comprises approximately 5.9 million square kilometres or 42 per cent of the Antarctic continent. Australia acknowledges that the Australian Antarctic Territory is not universally recognised, and supports the 1959 Antarctic Treaty and associated instruments (collectively known as the Antarctic Treaty Ssystem) as the best way of accommodating differing views on Antarctic sovereignty and protecting Australia’s national interests in the region. The Heard Island and McDonald Islands Territory is a sovereign part of Australia and is managed in accordance with the Heard Island and McDonald Islands Marine Reserve Management Plan. The Marine Reserve covers an area of approximately 71,200 square kilometres. The Australian Antarctic Division maintains permanent scientific research stations at Casey, Davis and Mawson in the Australian Antarctic Territory, and sub-Antarctic Macquarie Island (part of Tasmania). The Australian Antarctic Division is headquartered in Hobart, Tasmania. The distance from Hobart to the four research stations is 3443, 4838, 5475 and 1542 kilometres respectively. The research stations are supported by shipping and aviation capabilities – primarily a multi-role icebreaking vessel, chartered commercial and Royal Australian Air Force intercontinental aircraft to provide an airbridge to Wilkins Aerodrome ice runway (proximate to Casey Station) and smaller fixed and rotary wing aircraft. The Heard Island and McDonald 3 Island Territory is 4398 kilometres from Hobart. There are no permanent scientific research facilities only emergency shelters. Scientific and logistic support activity in Antarctica and the Southern Ocean is largely restricted to the Austral Summer Period between October and March. In addition to activity at the permanent research stations, during the summer research season remote field bases are also established to support coastal and inland activity. Dedicated marine science voyages also occur during this period. Access to, and delivery of, information is critical to the Australian Antarctic Program and advancing Australia’s national interests in the region. Enhancing Australia’s communications capability is also aligned with the Australian Antarctic Strategy and 20 Year Action Plan, which identifies the need to “Develop and promote Tasmania as the leading international Antarctic research hub and logistics Gateway for East Antarctica” and highlights “progressing options to modernise infrastructure at Australia’s three research stations”, and “improving access to East Antarctica, for our scientific research and operational needs”. Hobart is a globally-recognised Antarctic gateway of international diplomacy, operational support and logistics, and science services. The city serves as headquarters for key international Antarctic institutions such as the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) and the Agreement for the Conservation of Albatrosses and Petrels (ACAP) Secretariat. Hobart provides a technical services hub for maintenance and supply of specialised equipment, and logistics to several other national Antarctic programs. Current Availability and Access Communications between the Australian Antarctic Division’s headquarters in Hobart Tasmania, and Australia’s research stations are currently achieved through satellite infrastructure provided by SpeedCast via 7.3 metre diameter satellite antennas at each of the four stations. The antennas use C-band, providing a bandwidth of 9mbs with an added 300ms delay on all data communications. WAN compression technology via Exinda allows for slightly higher data rates while prioritising voice and medical communications over other network services. Each station has a backup data link via an Inmarsat Broadband Global Area Network (BGAN) with a very low bandwidth of up to 0.65Mbps and a delay of about 700ms. The Australian Antarctic Division makes extensive use of the Iridium satellite constellation with over 70 iridium handsets principally used for voice, but also for some data communications. The Australian Antarctic Division is currently trialling Iridium Certus for use during Antarctic traverses, and as a backup system to replace BGAN. The Australian Antarctic Division also use satellite tracking technology using a Garmin mobile tracker, to allow the tracking of personnel in the field. 4 Opportunities for Improving Infrastructure Undersea Fibre Cable to Antarctica Installation of a submarine fibre cable to the Australian Antarctic Territory would provide a stable, high-speed transfer connection to Australian Antarctic stations. The capacity of a fibre cable would be

Orientador: CMG (RM1) Leonardo Faria de Mattos Rio de Janeiro Escola de Guerra Naval 2019 2 AGRADECIMENTOS A minha esposa Nayara e meus filhos Felipe e Tomás pelo carinho, motivação e paciência dispensados durante a realização deste trabalho. Ao Capitão de Mar e Guerra Leonardo Faria de Mattos, meu orientador, pelas sugestões e intervenções extremamente profissionais, que foram de grande relevância para a realização deste estudo. 3 RESUMO O propósito da pesquisa foi identificar pontos de aderência do Tratado da Antártica, mais especificamente do Programa Antártico Australiano, com duas teorias das Relações Internacionais, opostas por definição: a Teoria Realista e a Teoria da Interdependência Complexa. A relevância do estudo reside na oportunidade de se entender como um programa de governo conquistou o apoio de sua sociedade e como ele obteve sucesso diante da ambiguidade do Tratado da Antártica, tendo em vista os interesses de alguns Estados em colonizar a região, bem como os de outros que enxergam a Antártica como uma região de cooperação internacional, livre, voltada exclusivamente para a pesquisa. Apesar da ambiguidade, o Tratado é considerado um caso de sucesso. Desde sua assinatura em 1959, a paz reinou na região, mesmo com a relativa ambiguidade nas visões, o que classifica o Tratado como um exemplo de sucesso dentre os regimes internacionais.

  • Assessment of Present and Planned Polar Research and Supply Vessels
    Assessment of Present and Planned Polar Research and Supply Vessels Candidate name: Felix Müller University of South-Eastern Norway Faculty of Technology, Natural Sciences and Maritime Sciences MASTER THESIS May 2018 Polar Research and Supply Vessels: Abstract 2 Abstract Polar research vessels are currently being planned or build by many nations engaged in polar science. This includes for example the British newbuilding RRS Sir David Attenborough and Australia’s RSV Nuyina. The study explores the field of Polar Research and Supply Vessels (PRSV) and investigates the possibilities of assessing their capabilities. An exploratory research approach is used to identifies sources of information and collects them into a database. Established models for performance assessment in the academic literature are presented. Links are drawn between those models, PSRV characteristics and the research field. An adapted model is created and applied on the data collected, providing the ability to assess capabilities of PRSV. The assessment is based on the four aspects size, icebreaking, logistic and science, each using several attributes from the database to provide a normalised score between 0 and 100. Data of five PRSV are used on this model and visualised in a radar diagram. Results show general applicability of the model and further development and refinement can result in a useful contribution for this focussed research field. Keywords: Exploratory Study, Polar Research and Supply Vessels, Capability Assessment, Icebreaking, Science, Logistic Polar Research and Supply Vessels: Acknowledgements 3 Acknowledgements Thank you Halvor Schøyen for being my supervisor during this thesis. Your encouraging and positive attitude towards my field of interests, even before this thesis started, is much appreciated.

  • The Australian Naval Architect
    Technical Meeting – 1 July 2020 Clive Evans, Maritime Systems Lead—Research Supply Icebreaker Project, Australian Antarctic Division, gave a presentation on RSV Nuyina: Australia’s New Icebreaking Research and Supply Vessel as a webinar hosted by Engineers Australia with Phil Helmore as MC on 1 July. This was our third webinar presentation, and attracted 250+ registrations, with 180+ actually participating on the evening. Introduction Clive began his presentation with a video introduction to the Australian Antarctic Program and the research and supply operations involved. This was followed with photos and more-detailed descriptions. Australia has three permanent research stations in Antarctica, at Casey, Davis and Mawson, and a permanent base on Macquarie Island, all of which have to be resupplied regularly with fuel, stores and solid cargo. Australian Antarctic Program stations (Map courtesy Australian Antarctic Program) Australian Antarctic station Casey (Photo courtesy Australian Antarctic Program) Aurora Australis resupplying Casey using landing craft (Photo courtesy David Barringhaus) Australian Antarctic station Davis (Photo courtesy Australian Antarctic Program) Aurora Australis resupplying Davis using helicopter (Photo courtesy William de Bruyn) Aurora Australis resupplying a new crane to Davis (Photo courtesy Mark Horstman) Australian Antarctic station Mawson (Photo courtesy Australian Antarctic Program) Aurora Australis resupplying Mawson (Photo courtesy Noel Tennant) Australian Antarctic station Macquarie Island (Photo courtesy Barry Becker) Aurora Australis resupplying Macquarie Island (Photo courtesy Jeremy Smith) Another task is for the transfer of expeditioners. Some arrive on an Airbus A319 which lands on the Wilkins runway close to Casey station, a four-hour flight from Hobart. However, most expeditioners arrive by ship, typically a ten-day trip, but can be delivered to any of the stations.
