The Antarctic Treaty System And
The Antarctic Treaty System and Law During the first half of the 20th century a series of territorial claims were made to parts of Antarctica, including New Zealand's claim to the Ross Dependency in 1923. These claims created significant international political tension over Antarctica which was compounded by military activities in the region by several nations during the Second World War. These tensions were eased by the International Geophysical Year (IGY) of 1957-58, the first substantial multi-national programme of scientific research in Antarctica. The IGY was pivotal not only in recognising the scientific value of Antarctica, but also in promoting co- operation among nations active in the region. The outstanding success of the IGY led to a series of negotiations to find a solution to the political disputes surrounding the continent. The outcome to these negotiations was the Antarctic Treaty. The Antarctic Treaty The Antarctic Treaty was signed in Washington on 1 December 1959 by the twelve nations that had been active during the IGY (Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, United Kingdom, United States and USSR). It entered into force on 23 June 1961. The Treaty, which applies to all land and ice-shelves south of 60° South latitude, is remarkably short for an international agreement – just 14 articles long. The twelve nations that adopted the Treaty in 1959 recognised that "it is in the interests of all mankind that Antarctica shall continue forever to be used exclusively for peaceful purposes and shall not become the scene or object of international discord". -

Review of the Geology and Paleontology of the Ellsworth Mountains, Antarctica
U.S. Geological Survey and The National Academies; USGS OF-2007-1047, Short Research Paper 107; doi:10.3133/of2007-1047.srp107 Review of the geology and paleontology of the Ellsworth Mountains, Antarctica G.F. Webers¹ and J.F. Splettstoesser² ¹Department of Geology, Macalester College, St. Paul, MN 55108, USA ([email protected]) ²P.O. Box 515, Waconia, MN 55387, USA ([email protected]) Abstract The geology of the Ellsworth Mountains has become known in detail only within the past 40-45 years, and the wealth of paleontologic information within the past 25 years. The mountains are an anomaly, structurally speaking, occurring at right angles to the Transantarctic Mountains, implying a crustal plate rotation to reach the present location. Paleontologic affinities with other parts of Gondwanaland are evident, with nearly 150 fossil species ranging in age from Early Cambrian to Permian, with the majority from the Heritage Range. Trilobites and mollusks comprise most of the fauna discovered and identified, including many new genera and species. A Glossopteris flora of Permian age provides a comparison with other Gondwana floras of similar age. The quartzitic rocks that form much of the Sentinel Range have been sculpted by glacial erosion into spectacular alpine topography, resulting in eight of the highest peaks in Antarctica.

Antarctic Treaty Handbook: Tourism
TOURISM AND OTHER NON-GOVERNMENTAL ACTIVITIES Introductory note Commercial tourism Until 1966 virtually all expeditions to the Antarctic had been organized by governments or had some measure of governmental backing. In that year there appeared in Antarctica for the first time a commercially organized, ship-borne tourist expedition. In subsequent years commercial tourism increased, using ships and aircraft. The area most frequently visited by sea was the Antarctic Peninsula. Regular airborne tourism began in 1977 and developed using long range passenger aircraft flying from Australia and New Zealand. Almost all of these flights overflew parts of Antarctica and returned home without landing. Airborne tourism diminished considerably following the tragic crash on Mount Erebus, Ross Island, on 28 November 1979 with the loss of 257 lives. Non-governmental non-tourist expeditions Such expeditions also began to appear in the Antarctic in 1966. The preparedness of such expeditions has varied; the consequent requests for assistance from governmental expeditions have sometimes caused disruption to scientific programs. A major aim of the consideration engendered by these expeditions within the Treaty fora has been to encourage such private expeditions to be adequately prepared and fully self-sufficient. Antarctic Treaty Recommendations XXI: Resolution 3 (1997) Standard Form for Advance Notification and Post-Visit Reporting on Tourism and Non-Governmental Activities in Antarctica The Representatives, Recalling Resolution 3 (1995) which agreed that there would be an advantage in standardized reporting of information on tourism and non-governmental activity in Antarctica; Noting that Attachment A to Recommendation 1 (1994) outlines the requirements for Advance Notice of tourism and non-governmental activities, and that Resolution 3 (1995) outlines requirements for post-activity reports; Recalling that Parties agreed at ATCM XX to trial a standard form for Advance Notification and Post-Visit Reporting during the 1996/97 Antarctic season. -
Development Pressures on the Antarctic Wilderness
XXVIII ATCM – IP May 2004 Original: English Agenda Items 3 (Operation of the CEP) and 4a (General Matters) DEVELOPMENT PRESSURES ON THE ANTARCTIC WILDERNESS Submitted to the XXVIII ATCM by the Antarctic and Southern Ocean Coalition DEVELOPMENT PRESSURES ON THE ANTARCTIC WILDERNESS 1. Introduction In 2004 the Antarctic and Southern Ocean Coalition (ASOC) tabled information paper ATCM XXVII IP 094 “Are new stations justified?”. The paper highlighted proposals for the construction of no less than five new Antarctic stations in the context of at least 73 established stations (whether full year or summer only), maintained by 26 States already operating in the Antarctic Treaty Area. The paper considered what was driving the new station activity in Antarctica, whether or not it was necessary or desirable, and what alternatives there might be to building yet more stations. Whilst IP 094 focused on new station proposals, it noted that there were other significant infrastructure projects underway in Antarctica, which included substantial upgrades of existing national stations, the development of air links to various locations in Antarctica and related runways, and an ice road to the South Pole. Since then, ASOC has become aware of additional proposals for infrastructure projects. This paper updates ASOC’s ATCM XXVII IP 094 to include most infrastructure projects planned or currently underway in Antarctica as of April 2005, and discusses their contribution to cumulative impacts. The criteria used to select these projects are: 1. The project’s environmental impact is potentially “more than minor or transitory”; 2. The project results in a development of infrastructure that is significant in the Antarctic context; 3. -
Mcmurdo Dry Valleys, Southern Victoria Land
Measure 1 (2004) Annex Management Plan for Antarctic Specially Managed Area No. 2 MCMURDO DRY VALLEYS, SOUTHERN VICTORIA LAND 1. Description of values to be protected and activities to be managed The McMurdo Dry Valleys are characterized as the largest relatively ice-free region in Antarctica with approximately thirty percent of the ground surface largely free of snow and ice. The region encompasses a cold desert ecosystem, whose climate is not only cold and extremely arid (in the Wright Valley the mean annual temperature is –19.8°C and annual precipitation is less than 100 mm water equivalent), but also windy. The landscape of the Area contains glaciers, mountain ranges, ice-covered lakes, meltwater streams, arid patterned soils and permafrost, sand dunes, and interconnected watershed systems. These watersheds have a regional influence on the McMurdo Sound marine ecosystem. The Area’s location, where large-scale seasonal shifts in the water phase occur, is of great importance to the study of climate change. Through shifts in the ice-water balance over time, resulting in contraction and expansion of hydrological features and the accumulations of trace gases in ancient snow, the McMurdo Dry Valley terrain also contains records of past climate change. The extreme climate of the region serves as an important analogue for the conditions of ancient Earth and contemporary Mars, where such climate may have dominated the evolution of landscape and biota. The Area is characterized by unique ecosystems of low biodiversity and reduced food web complexity. However, as the largest ice-free region in Antarctica, the McMurdo Dry Valleys also contain relatively diverse habitats compared with other ice-free areas. -

We present a new digital elevation model (DEM) of the bed, with a 1 km gridding, of the Weddell Sea (WS) sector of the West Antarctic Ice Sheet (WAIS). The DEM has a total area of ∼ 125 000 km2 covering the Institute, Möller and Foundation ice streams, as well as the Bungenstock ice rise. In comparison with the Bedmap2 product, our DEM includes new aerogeophysical datasets acquired by the Center for Remote Sensing of Ice Sheets (CReSIS) through the NASA Operation IceBridge (OIB) program in 2012, 2014 and 2016.
