The International Collaboration Effort for Improving Paleoclimate Research in the Southern Ocean (ICEPRO) aims to improve our understanding of past ocean-ice-earth interactions by linking modern observations and paleo-records by facilitating transnational collaborations on (paleo)environmental studies in the Southern Ocean. To reach this goal, ICEPRO will bring together international partners to coordinate and harmonize joint research activities in terms of sampling strategies, methodologies, proxy calibrations and the development of future Antarctic expeditions.
