  • The Continental Shelf of Antarctica: Implications of the Requirement to Make a Submission to the CLCS Under Article 76 of the LOS Convention
    The Continental Shelf of Antarctica: Implications of the Requirement to Make a Submission to the CLCS under Article 76 of the LOS Convention Alex G. Oude Elferink* Netherlands Institute for the Law of the Sea, Utrecht University, The Netherlands ABSTRACT This article looks at the question of how the obligation of states parties to the United Nations Convention on the Law of the Sea to submit information on the outer limit of their continental shelf to the Commission on the Limits of the Continental Shelf and the regime established by the Antarctic Treaty can be reconciled. Under the latter Treaty states have 'agreed to disagree' about the legal status of Antarctica. The establishment of an outer limit of the continental shelf on the basis of the recommendations of the Commission on the Limits of the Continental Shelf would pose a threat to this agreement to disagree as it would recognise the existence of coastal states and maritime zones. The article sets out the options of the states involved to deal with this issue. It is concluded that there are a number of approaches which safeguard the rights of coastal states under the United Nations Convention on the Law of the Sea and the agreement to disagree of the Antarctic Treaty. Introduction The Antarctic continent and the adjacent sea areas are governed by a special treaty regime. Reconciling this regime with the general international law of the sea has posed considerable challenges. At present, such a reconciliation has to be found in respect of the requirements for the establishment of the outer limits of An earlier version of this article was presented at the Southern Ocean Law of the Sea and Maritime Disputes Workshop, Faculty of Law, University of Sydney, Australia, 19 October 2001.

  • Changing Polar Geography
    6 Changing Polar Geography PHYSICAL GEOGRAPHY OF THE POLAR REGIONS Landforms The earth is shaped as if some huge thumb pushed in a dent at the north pole that popped land out at the south pole. The result is that the north polar region is a large basin and that the south polar region is the elevated Antarctic continent. The basin at the north is filled with the waters of the Arctic Ocean, and the land south of the basin (from 55° N to 80° N) slopes toward the pole. By contrast, the Antarctic continent is the highest of all the continents, averaging 6,000 feet in elevation. Most of the Arctic Ocean is frozen year-round, and the Antarctic ice sheet covers nearly the entire continent. One moving part of the Antarctic ice sheet forms the world's largest glacier, the Lambert. Ice can be considered a type of landform in the polar areas. The north polar seas have three types of sea ice. The fast ice grows outward from the shoreline and in the winter joins the pack ice, the drifting layer of ice that is constantly on the move. It tends to circle the North Pole, which occupies the central part of the Arctic Ocean, is stationary and about 10 feet thick, It does not freeze and deeper into the water, because its own thickness insulates the water from the cold air temperatures. However, rafting of broken pieces one upon another causes thick ice ridges that are common in both the pack ice and the polar ice and make travel over the surface very difficult.

  • Managing Tourism in Antarctica – a Framework for the Future
    Managing Tourism in Antarctica – A Framework for the Future Harry Maher A thesis submitted for the degree of Masters of Tourism At the University of Otago, Dunedin New Zealand Date: 19 December 2005 i Abstract Antarctic tourism has been the subject of significant debate in recent years, not only within the Antarctic Treaty System (ATS) but also in the wider community. A relatively recent but now well-established industry, tourism in Antarctica is characterised by high regional growth rates and the potential for significant impacts on the environments where it occurs. This thesis addresses the research question ‘Is the current regulatory system for managing tourism in Antarctica adequate to protect the Antarctic environment?’ It examines the general theories of management of tourism and recreation in protected and wilderness areas. The importance of the relationship between site values, tourism activities, impacts and management responses is highlighted. It is noted that contemporary protected area managers inevitably put in place robust and binding legislation, site-specific management plans, and management interventions to manage wilderness areas. The tourism management framework for Antarctica is presented, in both its historical and contemporary contests. The historical and current size and nature of the Antarctic tourist industry is analysed and presented, along with an in- depth examination of the values and attributes of the sites where that activity occurs. The actual and potential impacts of tourism in general and of the current levels of tourism in Antarctica are then discussed. A discussion regarding the adequacy of the current ATS tourism management regime is presented. The system is found to be inadequate across a range of critical factors.

  • Hydrochemistry of Ice-Covered Lakes and Ponds in the Untersee Oasis (Queen Maud Land, Antarctica)
    Hydrochemistry of ice-covered lakes and ponds in the Untersee Oasis (Queen Maud Land, Antarctica) Benoit Faucher Thesis submitted to the University of Ottawa in partial Fulfillment of the requirements for the Doctorate of Philosophy in Geography Department of Geography, Environment, and Geomatics Faculty of Arts University of Ottawa © Benoit Faucher, Ottawa, Canada, 2021 ABSTRACT Several thousand coastal perennially ice-covered oligotrophic lakes and ponds have been identified on the Antarctic continent. To date, most hydrochemical studies on Antarctica’s ice- covered lakes have been undertaken in the McMurdo Dry Valleys (more than 20 lakes/ponds studied since 1957) because of their proximity to the McMurdo research station and the New Zealand station Scott Base. Yet, little attention has been given to coastal ice-covered lakes situated in Antarctica’s central Queen Maud Land region, and more specifically in the Untersee Oasis: a polar Oasis that encompasses two large perennially ice-covered lakes (Lake Untersee & Lake Obersee), and numerous small ice-covered morainic ponds. Consequently, this PhD research project aims to describe and understand the distribution, ice cover phenology, and contemporary hydrochemistry of perennially ice-covered lakes and ponds located in the Untersee Oasis and their effect on the activity of the benthic microbial ecosystem. Lake Untersee, the largest freshwater coastal lake in central Queen Maud Land, was the main focus of this study. Its energy and water mass balance was initially investigated to understand its current equilibrium and how this perennially well-sealed ice-covered lake may evolve under changing climate conditions. Results suggest that Lake Untersee’s mass balance was in equilibrium between the late 1990s and 2018, and the lake is mainly fed by subglacial meltwater (55-60%) and by subaqueous melting of glacier ice (40-45%).

  • DODDS Antarctic Geopolitics
    13. Antarctic geopolitics Klaus Dodds INTRODUCTION In 1957, a writer called John Andrews stole my proverbial thunder. He published an article called ‘Antarctic geopolitics’ in the journal, Australian Outlook, and it makes for intriguing reading some six decades later.1 I never had the pleasure of meeting Andrews but it would have been instructive, for me at least, to talk with him about how our mutual understandings of both geopolitics and Antarctica might have aligned with one another or not. Assuming he was writing in 1956 or early 1957, he was writing at an interesting time for both subject areas. In the case of geopolitics, for example, established scholars such as Richard Hartshorne were urging a new generation of political geographers to avoid the term ‘geopolitics’, positing the claim that it was an ‘intellectual poison’. What poisoned this academic field was a deeply felt unease that an association with Nazi Germany and Nazism had forever tainted geopolitics as both thought and practice. Hartshorne urged his fellow geogra- phers to seek solace in mainstream political geography, and the emerging scholarly fields of quantitative and behavioural geography.2 What was interesting, however, was that non- geographers were still willing to use the term ‘geopolitics’ in their analyses of world affairs – and that in Latin America geopolitics was widely taught in military colleges and universities.3 Andrews was also writing at an interesting time in Antarctic history. In 1957, the Soviet satellite Sputnik and the onset of the International Geophysical Year (IGY 1957–8) mani- fested a new era of scientific inquiry.4 The IGY was an extraordinary and intense period of international scientific investigation in Antarctica and other areas such as the oceans and the upper atmosphere, which transformed understanding of the polar continent and its relationship to planet Earth and the planetary system.

    Antarctica•Biodiversity in the Southern Ocean Lesson by Mellie Lewis Jonathan Bird goes to the bottom of the blue world, Antarctica in the Southern Ocean. What marine life can live in freezing water? Jonathan is amazed at the biodiversity of the Southern Ocean. He finds numerous colorful invertebrates such as sponges, limpets, sea stars, anemones and sea cucumbers. Jonathan is excited when he finds a gigantic jellyfish three feet across with 50-foot tentacles, small fish that have “antifreeze” to prevent them from freezing and penguins that cannot fly, but put on a spectacular underwater acrobatic show. The Leopard seal is an apex predator of Antarctica, yet a curious 12-foot seal poses curiously for Jonathan for over an hour. Jonathan explores the towering walls of icebergs underwater. Above the water, Jonathan is in awe of the majestic beauty of Antarctica.

Elliot Objectives After reviewing the pictures from the PolarTREC expedi- tions (see links below) to Antarctica, students develop a photo essay illustrating the Five Themes of Geography as they relate to the Antarctic region. Students will ex- plain how the images selected accurately portray the theme. The photo galleries of the PolarTREC teachers include a variety of maps that can be incorporated to help identify the location of each theme portrayed. Lesson Preparation Integrated teaching practices provide the opportunities to develop critical thinking, vocabulary enhancement and creative application of content to student-based learning activities. Expository writing is one method to foster creative expression while utilizing the appropriate topical vocabulary however, it is not the only way to make the geography of a place come alive and have a meaningful purpose to a student. Geographic curric- ulum is brought to life through vivid descriptions of plac- es, regions, and interactions between peoples, ideas and the environment at different levels of scale through a spatial context over time.
