  • Ice and Laser
    Based on significant technological advances and unconventional approaches, the ICE&LASERS project aims at revolutionizing ice core research by developing new tools based on laser physics.
    The main challenge consists in inventing, constructing and testing an in-situ probe to evaluate if a target site is suitable to recover ice as old as 1,5 million years, all within a single season in Antartica.
    A second challenge is to build and use new laser instruments for accurate and detailed evaluation of stable isotopic ratios of greenhouse gases trapped in ice cores.

  • Antarctique Traverse EAIIST
    EAIIST, East Antarctic International Ice Sheet Traverse is a collaborative international project aiming to study unexplored glacial terrain, to decipher the cryospheric climate archives and to better predict sea level rise. The EAIIST project proposes an autonomous scientific traverse to study the icy terrain of the Antarctic continent in one of its driest places, between the French-Italian station Concordia and the US South Pole station.

  • Beyond-EPICA & Oldest Ice
    In Antarctica internationally leading ice and climate scientists of 14 institutions from ten European countries are looking for the oldest ice-core record on Earth. Goal of the project "Beyond EPICA - Oldest Ice" is to find the ice core which goes furthest back in Earth’s history.

  • Ice Memory
    The Ice Memory project aims at creating a global ice archive sanctuary in Antarctica, a continent devoted to science and peace, in an effort to preserve ice cores from the world’s key endangered glaciers. That way, scientists in the decades and centuries to come will still have enough high-quality raw material to investigate and make future discoveries.
  • ERC Proof of Concept OCEAN-IDs

    It is currently chanllenging to describe snow accumulation in Antarctica. This question is critical because an increasing storage of snow in Antarctica would reduce the sea level rise. But what is actually going on? Does accumulation increase or is it reducing?

  • Project PRC ECYME
    Methane (CH4) is a major greenhouse gas and its role within the climatic system is central. Improving our understanding of the processes driving its biogeochemical budget requires to better characterize the past variations of it atmospheric composition at the middle northern latitudes. These areas indeed cumulate natural and anthropogenic CH4 sources. The ECYME project aims to reconstruct mid-latitude atmospheric CH4 variations over the last 1000yrs using an ice core drilled at the Chongce site (Tibet). The frame of this project is a unique French-Chinese collaboration involving Nanjin University, IGE and LSCE. CH4 will be measured at high resolution along the ice core (IGE), to constrain the methane budget in simulations (pre-industrial times) conducted with the global climate-chemistry couplet model LMDz-INCA (LSCE).
