Takahe, two West Antarctica volcanic centers have produced a number of explosive, ashfall generating eruptions over the past 500,000 yrs. These eruptions dispersed volcanic ash over large areas of the West Antarctic ice sheet. Evidence of these eruptions is observed at two blue ice sites (Mt. Waesche and Mt. Moulton) as well as in the Siple Dome and Byrd (Palais et al., 1988) ice cores. Geochemical correlations between tephra sampled at the source volcanoes, at blue ice sites, and in the Siple Dome ice core suggest that at least some of the eruptions covered large areas of the ice sheet with a volcanic ash, and 40 Ar/ 39 Ar dating of volcanic material provides precise timing when these events occurred. Volcanic ash from some of these events expected to be found in the WAIS Divide ice core, providing chronology and inter-site correlation.

  • The Human Footprint of the IPY 2007-2008 in Antarctica
    IP 86 Agenda Item: ATCM 10 CEP 5 Presented by: ASOC Original: English The Human Footprint of the IPY 2007-2008 in Antarctica Attachments: 1 IP 86 The Human Footprint of the IPY 2007-2008 in Antarctica Information Paper Submitted by ASOC to ATCM XXX (CEP Agenda Item 5; ATCM Agenda Item 10) Abstract The International Polar Year (IPY) 2007-2008 is ambitious in scope and scale. At least 350 research activities with Antarctic or bipolar focus will take place during the IPY period of March 2007-March 2009. 82% (or 286) of them are planning to conduct fieldwork in Antarctica (Fig. 1a). 105 activities are planning to leave behind physical infrastructure, ranging from extensive arrays of instrumentation to new facilities. The Antarctic Treaty Secretariat’s database of environmental impact assessments lists only 7 completed assessments that are directly linked to science or logistics that are planned for the IPY. During the IPY, research and its corresponding logistical support activity will intensify around existing centers of research, such as the Antarctic Peninsula, Dronning Maud Land, Prydz Bay and the Weddell and Ross Seas. A number of large-scale research activities has also been planned in areas which have been hitherto seldom accessed, including the Gamburtsev Mountains in East Antarctica, the Amundsen Sea embayment and the West Antarctic ice sheet and subglacial lakes (Fig. 2). Many of them have been planned as the precursor of long-term research programs. In view of the ensemble of the research projects that have been endorsed, the IPY is likely to lead to: ! a direct increase in human activity in Antarctica; ! an increase in infrastructure in Antarctica; ! an increased pressure on Antarctica’s wilderness values; ! an increased level of interest in Antarctica, which can indirectly generate more activities other than scientific research, adding to the current trend of rapid growth and diversification of Antarctic tourism.

During 1882-83 eleven countries cooperated in a project to study the geophysics and geodesy of the polar regions by establishing 14 research stations. Three of these were located in Canada’s Arctic: one each by the United States, Germany and Britain. They accumulated dataon terrestial magnetism and boreal phenomena and brought back valuable informationon arctic living. This year will mark the 100th anniversary of the first mathematical work. With his colleague Wilhelm Weber he International Polar Year, probably the most ambitious of established in 1836 the Gottingen Magnetic Union(Mag- 19th-century international scientific projects and the fore- netische Verein) which united a world-wide network of runner of more recent cooperative ventures such as Inter- observatories.

  • West Antarctic Ice Sheet Divide Ice Core Climate, Ice Sheet History, Cryobiology
    WAIS DIVIDE SCIENCE COORDINATION OFFICE West Antarctic Ice Sheet Divide Ice Core Climate, Ice Sheet History, Cryobiology A GUIDE FOR THE MEDIA AND PUBLIC Field Season 2011-2012 WAIS (West Antarctic Ice Sheet) Divide is a United States deep ice coring project in West Antarctica funded by the National Science Foundation (NSF). WAIS Divide’s goal is to examine the last ~100,000 years of Earth’s climate history by drilling and recovering a deep ice core from the ice divide in central West Antarctica. Ice core science has dramatically advanced our understanding of how the Earth’s climate has changed in the past. Ice cores collected from Greenland have revolutionized our notion of climate variability during the past 100,000 years. The WAIS Divide ice core will provide the first Southern Hemisphere climate and greenhouse gas records of comparable time resolution and duration to the Greenland ice cores enabling detailed comparison of environmental conditions between the northern and southern hemispheres, and the study of greenhouse gas concentrations in the paleo-atmosphere, with a greater level of detail than previously possible. The WAIS Divide ice core will also be used to test models of WAIS history and stability, and to investigate the biological signals contained in deep Antarctic ice cores. 1 Additional copies of this document are available from the project website at http://www.waisdivide.unh.edu Produced by the WAIS Divide Science Coordination Office with support from the National Science Foundation, Office of Polar Programs. 2 Contents
