West Antarctic Ice Sheet (WAIS) Divide Camp WAIS Divide Camp is a seasonal Antarctic research station established to support deep ice-core drilling and paleoclimate studies near the WAIS divide. The camp has hosted multidisciplinary teams conducting glaciological, atmospheric, and geophysical research in collaboration with international partners and national programs. Researchers from institutions such as National Science Foundation, University of Wisconsin–Madison, British Antarctic Survey, Lamont–Doherty Earth Observatory, and University of Cambridge have operated at the site under logistical support from United States Antarctic Program and contractor organizations.

Overview

The camp occupies a high-elevation site on the West Antarctic Ice Sheet adjacent to major research locales and transit routes used by McMurdo Station, Amundsen–Scott South Pole Station, and field camps supporting projects tied to the International Thwaites Glacier Collaboration and Polar Research Board. Facilities include a central drilling trench for the WAIS Divide deep core, snow runs, instrumentation arrays for measuring firn properties, and temporary living modules erected each Austral summer under standards set by Antarctic Treaty System signatories. Scientific objectives have intersected with programs at Scripps Institution of Oceanography, National Aeronautics and Space Administration, National Oceanic and Atmospheric Administration, and universities across the United States, United Kingdom, France, and Germany.

History and Establishment

Planning for a deep ice-core campaign at the WAIS divide grew from proposals submitted to the Scientific Committee on Antarctic Research and discussions at the International Glaciological Society meetings. Early reconnaissance campaigns involved field teams from Ohio State University, Columbia University, and the University of New Hampshire along routes connecting to long-range logistics hubs such as Pine Island Glacier staging areas and Byrd Station resupply corridors. Construction of the seasonal camp began following award decisions by the National Science Foundation and coordination with the United States Antarctic Program; initial deep drilling operations commenced in the mid-2000s with support contracts awarded to polar service providers experienced with operations for Antarctic Logistics and Missions and other contractors.

Scientific Research and Projects

WAIS Divide Camp supported a flagship deep-ice core project that produced high-resolution records of greenhouse gases, isotopes, and volcanic markers used by researchers at Lamont–Doherty Earth Observatory, University of Bern, and University of Oregon. Studies integrated ice-core chemistry with airborne surveys by NASA missions and satellite observations from Landsat, ICESat, and CryoSat to contextualize accumulation and ice-flow dynamics linked to the Amundsen Sea Embayment and Ross Sea sector. Projects at the camp encompassed collaborations with the PAGES initiative, the IPCC community through paleoclimate working groups, and targeted efforts by laboratories at Harvard University and Massachusetts Institute of Technology. Instrumentation deployments included ground-penetrating radar arrays used by teams from University of Alaska Fairbanks and seismic experiments coordinated with Lamont–Doherty Earth Observatory.

Logistics and Facilities

Logistical operations integrated fixed-wing ski-equipped aircraft flights contracted through Kenn Borek Air and aerial support from New York Air National Guard assets during periods when intercontinental flights connected to McMurdo Station and Christchurch Airport. On-site infrastructure comprised insulated living huts, a central drilling camp run by crews from University of Wisconsin–Madison and contractors, power-generation systems maintained to standards advocated by the Council of Managers of National Antarctic Programs, and fuel caches staged along snow roads to support tractor convoys similar to operations linking Byrd Station and coastal depots. Communication links relied on satellite constellations used by Iridium Communications and data relay services coordinated with National Science Foundation network operations.

Environmental Impact and Safety

Environmental management at the camp followed protocols under the Antarctic Treaty Consultative Meeting framework and Environmental Protocol measures administered by the Committee for Environmental Protection. Waste handling, fuel storage, and wildlife disturbance mitigation plans were developed in consultation with specialists from British Antarctic Survey and environmental officers from national Antarctic programs. Safety systems included field medical capabilities consistent with standards from Antarctic Medicine programs and emergency evacuation coordination with Air National Guard and civilian polar contractors. Environmental monitoring programs tracked local snow chemistry and black-carbon deposition with contributions from researchers at University of Colorado Boulder and NOAA laboratories.

Notable Findings and Publications

Data derived from the WAIS Divide deep core contributed to high-resolution reconstructions of atmospheric carbon dioxide and methane spanning glacial–interglacial cycles, informing assessments by the IPCC and paleoclimate syntheses published by teams affiliated with Lamont–Doherty Earth Observatory, University of Copenhagen, and University of Bern. Peer-reviewed articles in journals edited by organizations such as the American Geophysical Union and Nature included multi-proxy analyses of abrupt climate events, volcanic aerosol chronologies tied to eruptions catalogued by researchers at Smithsonian Institution and ice-sheet dynamics studies referenced in reports by the International Cryosphere Climate Initiative. Long-term datasets from WAIS Divide have been archived and used by modeling groups at National Center for Atmospheric Research, Princeton University, and ETH Zurich to evaluate ice-sheet stability and sea-level projections.
