European Project for Ice Coring in Antarctica is a multinational scientific program that coordinated deep ice-core drilling and analysis in Antarctica to reconstruct past climate and atmospheric composition. The effort linked specialists from European Union, European Commission, national research institutes such as British Antarctic Survey, Alfred Wegener Institute, University of Bern, and international partners including National Science Foundation (United States), National Institute of Polar Research (Japan), producing high-resolution paleoclimate records used by Intergovernmental Panel on Climate Change and cited across Nature (journal), Science (journal), and other leading publications.
Overview
EPICA conducted deep ice-core drilling at multiple Antarctic sites to obtain continuous records of greenhouse gases, stable isotopes, and particulate matter spanning several glacial cycles. The program integrated expertise from paleoclimatology, glaciology, and ice-core chemistry communities based at institutions like Université de Grenoble Alpes, Istituto Nazionale di Geofisica e Vulcanologia, CNRS, Max Planck Society, and ETH Zurich. EPICA outputs informed panels such as the Intergovernmental Panel on Climate Change and databases maintained by World Data Center for Paleoclimatology and PANGAEA (data publisher).
History and Organization
EPICA was launched in the mid-1990s under European coordination with significant contributions from national programs including British Antarctic Survey, Alfred Wegener Institute (AWI), Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS), and Centre National de la Recherche Scientifique (CNRS). Early planning involved meetings at European Commission venues and scientific workshops at European Geosciences Union assemblies, with steering committees drawing representatives from Italy, France, Germany, Belgium, Netherlands, Switzerland, Norway, Sweden, and United Kingdom. Operational logistics were coordinated with polar platforms such as Dronning Maud Land, Concordia Station, and Neumayer Station III, and liaison occurred with programs like U.S. Antarctic Program, Japanese Antarctic Research Expedition, and Russian Antarctic Expedition.
Scientific Objectives and Methods
Primary EPICA objectives included reconstructing atmospheric CO2 and CH4 concentrations, temperature proxies from oxygen and hydrogen isotopes, and dust, sea-salt, and volcanic aerosol records to interpret climate forcings and feedbacks across multiple glacial-interglacial cycles. Analytical techniques were developed and applied at laboratories including Laboratoire des Sciences du Climat et de l'Environnement, University of Bern Ice Core Laboratory, and Max Planck Institute for Chemistry using methods such as gas extraction, isotope ratio mass spectrometry, and continuous flow analysis. The program aimed to resolve mechanisms described in frameworks like Milankovitch theory, Bølling–Allerød, Younger Dryas, and to test hypotheses about abrupt climate change documented in records such as Greenland ice core records and Vostok (station) cores.
Drill Sites and Expeditions
Major EPICA drill sites included EPICA Dome C on the Antarctic Plateau and collaborative access to sites near Dome F and Dome Fuji Station. Expeditions staged from logistical hubs such as Concordia Station and McMurdo Station and used traverse routes across Antarctic Plateau and Kerguelen Plateau support areas. Field teams composed of personnel from British Antarctic Survey, Alfred Wegener Institute, Istituto Nazionale di Geofisica e Vulcanologia, CNRS, Scott Polar Research Institute, and University of Copenhagen executed multi-season campaigns using drills derived from systems developed at WISSARD, CryoEpi (prototype), and technologies originally advanced by BAS (British Antarctic Survey) engineers and Ifremer partners.
Key Findings and Contributions to Climate Science
EPICA cores produced continuous climate records extending back 800,000 years, documenting glacial-interglacial cycles, the evolution of atmospheric carbon dioxide and methane concentrations, and the coupling between greenhouse gases and Antarctic temperature. These results corroborated and extended findings from Vostok (station) and Greenland ice core records and clarified pacing mechanisms linked to Milankovitch cycles, orbital forcing, and internal climate feedbacks involving ice-sheet dynamics and ocean circulation shifts such as changes in the Atlantic Meridional Overturning Circulation. EPICA data underpinned assessments in IPCC Fourth Assessment Report and later syntheses, influenced research at centers like Lamont–Doherty Earth Observatory, Scripps Institution of Oceanography, and informed climate models from groups including Met Office Hadley Centre, CESM, MPI-ESM, and EC-Earth.
Logistics, Equipment, and Field Operations
Field logistics combined airlift support from C-130 Hercules and ski-equipped aircraft, over-snow traverses with tractor trains, and field camps modeled after Concordia Station operations. Core recovery relied on electromechanical and thermal drill systems adapted for deep drilling in cold, high-accumulation settings; support equipment and laboratories involved partners such as Epiroc, PistenBully, RACAL instrumentation suppliers, and university workshops at ETH Zurich and TU Delft. Health, safety, and environmental compliance aligned with protocols from Antarctic Treaty System, Protocol on Environmental Protection to the Antarctic Treaty, and coordination with national operators including Norwegian Polar Institute and US Antarctic Program.
Collaborations and Funding Sources
EPICA was funded through a consortium of European national research councils, the European Commission framework programs, and contributions from agencies such as Swiss National Science Foundation, Deutsche Forschungsgemeinschaft, Centre National de la Recherche Scientifique, Italian Ministry of Education, Universities and Research, Netherlands Organisation for Scientific Research, and international partners including National Science Foundation (United States) and Japan Society for the Promotion of Science. Scientific collaboration extended to institutions like University of Cambridge, University of Copenhagen, Ghent University, Università degli Studi di Milano, University of Oslo, Uppsala University, Stockholm University, Leipzig University, and data stewardship with PANGAEA (data publisher) and NOAA Paleoclimatology programs.
