Loss of ice in the Arctic system: geological perspective of global environmental change
Strategic research project of the University of Oulu
Focus institute: Kvantum
Faculty: Oulu Mining School
The research group has an important task to study and fully understand the role of the glaciated high latitude areas as a part of the Earth system in order to setting boundary conditions for future climate and environmental change. The research group owns expertise of the Eurasian Arctic ice-sheet distribution and ice streaming during melting episodes in the Arctic land environment as well as successfully use mineralogical, including clay and heavy minerals, radiogenic isotope proxies and other source area fingerprints in sediments for study sediment distribution and meltwater releases in the Arctic marine environment. Sediment geochemistry and varietal mineral geochemical data has been successfully used to evaluate glacial dynamics, decay of ice-sheets and related meltwater plumes. The use of infrastructures at our disposal are such as the International Ocean Discovery Program (IODP) and the cutting-edge equipment and laboratory facilities of the Center for Microscopy and Nanotechnology in Oulu and Finland Isotope Geoscience Laboratory in Espoo. This project will much benefit from the close international collaboration in Palaeo-Arctic Spatial and Temporal (PAST) Gateways program.
