Dome Fuji Dome Fuji is a high Antarctic ice dome on the East Antarctic Plateau notable for deep ice cores, high elevation, and extreme cold. The site is a focus of international paleoclimatology and glaciology research linking to major programs and facilities such as International Polar Year, National Institute of Polar Research (Japan), United States Antarctic Program, European Project for Ice Coring in Antarctica, and Antarctic Treaty System. Its scientific importance connects to projects including the Vostok Station cores, EPICA cores, and collaborations with institutions such as University of Tokyo, Scott Polar Research Institute, Lamont–Doherty Earth Observatory, and Alfred Wegener Institute.

Geography and Geology

Dome Fuji sits on the Antarctic Plateau near the boundary of the East Antarctic Ice Sheet, within the Transantarctic Mountains drainage divide and proximate to features like Dome A, Dome C, Vostok and the Shirase Glacier. The ice dome is characterized by quasi-spherical ice flow over Precambrian cratonic bedrock of the East Antarctic Shield and is influenced by the Kerguelen Plateau-adjacent atmospheric circulation and the regional high-pressure system tied to the Southern Ocean and Ross Sea sector. Elevation exceeds 3,700–3,800 metres, affecting ice deformation, basal thermal regime, and subglacial hydrology near features such as the Aurora Subglacial Basin and Wilkes Subglacial Basin.

Climate and Glaciology

The climate at the site is among the coldest on Earth, with mean annual temperatures comparable to records from Dome A, Vostok Station, and Concordia Station, and episodic katabatic flows associated with the Antarctic Circumpolar Current and the Amundsen Sea Low. Surface mass balance is dominated by very low accumulation rates, similar to East Antarctic Plateau regimes studied by teams from British Antarctic Survey and Institute of Arctic and Alpine Research. Ice dynamics involve slow horizontal flow, internal deformation, and englacial stratigraphy that preserve climatic signals used by ice core researchers from institutions like University of Wisconsin–Madison and University of Bern.

Ice Core Research and Paleoclimate Records

The site has yielded deep ice cores providing paleoclimate records that complement those from Vostok, EPICA Dome C, and Law Dome. Cores recovered by National Institute of Polar Research (Japan) and collaborators reached significant depths, resolving greenhouse gas concentrations (e.g., CO2, CH4) measured with precision techniques developed at Scripps Institution of Oceanography, Woods Hole Oceanographic Institution, and Max Planck Institute for Chemistry. Chronologies from Dome Fuji cores have been correlated with volcanic marker horizons recognized in Mount Pinatubo and Tambora studies, and aligned with isotopic records used by researchers at Columbia University and ETH Zurich to reconstruct glacial–interglacial cycles and abrupt events comparable to those captured in Greenland ice core archives like GRIP and GISP2.

Scientific Stations and Logistics

The Japanese Dome Fuji Station and associated field camps operate seasonally and involve logistics coordinated with Japanese Antarctic Research Expedition, McMurdo Station operations under United States Antarctic Program, and air support similar to services from New Zealand Antarctic Programme and Australian Antarctic Division. Transport uses ski-equipped aircraft like the LC-130 Hercules and over-snow traverses resembling operations to Concordia Station and Princess Elisabeth Antarctica. Field science employs instrumentation from National Oceanic and Atmospheric Administration, NASA, European Space Agency, and university partners for snow chemistry, radar sounding, and borehole logging.

Environmental Protection and Conservation

Activities at the site are governed by the Antarctic Treaty System, Protocol on Environmental Protection to the Antarctic Treaty (Madrid Protocol), and management principles developed during Scientific Committee on Antarctic Research meetings. Environmental impact assessments are required by Japanese Ministry of the Environment guidelines applied in coordination with CCAMLR considerations and pollution prevention practices modeled after SCAR recommendations and the United Nations Framework Convention on Climate Change reporting frameworks used by participating nations.

History of Exploration and Naming

Exploration and scientific use of the dome were initiated during campaigns by the Japanese Antarctic Research Expedition in the late 20th century, following reconnaissance efforts by parties linked to Soviet Antarctic Expeditions, Australian Antarctic Division surveys, and mapping from aerial photography conducted by US Geological Survey and British Antarctic Survey. Naming reflects Japan’s programmatic involvement, with field seasons involving researchers from Hokkaido University, Nagoya University, Kyoto University, and international collaborators from Purdue University and University of Brussels.
