Grant Changes of water isotopes in Arctic Sea ice, Ocean, and atMosphere (CiASOM) (2021-2024) The main goal of the Changes of water isotopes in Arctic Sea ice, Ocean, and atMosphere (CiASOM) project is [...] this end, caves and permafrost exposure will be studied in East Siberia along a transect from the Arctic Ocean to the Lake Baikal. The objectives of the project are to: (i) Reconstruct (a) mean interglacial [...] to provide a comprehensive description of the present-day Arctic water cycle and related key exchange processes between the atmosphere, ocean, and sea ice, using both instrumental data and climate simulations

learning and deep learning for permafrost region remote sensing applications Remote sensing of Arctic Ocean Color Upscaling of permafrost region field measurements with remote sensing Generating permafrost

provide answers to big questions on polar and global climate change. Future climate change in the Arctic and Antarctic depends on feedbacks governed by small-scale processes: How do the surface fluxes of [...] momentum and particles change as the atmosphere becomes less stable, and as sea ice gives way to open ocean? How do clouds and precipitation change in response to changes in temperature, moisture, circulation

improve the understanding of polar atmospheric processes and their interactions with sea ice and ocean in the global context. We combine long term observations from ground stations and innovative measurements [...] improving the representation of polar processes in regional to global scale climate models. We run the Arctic research station AWIPEV on Svalbard and the meteorological and atmospheric observatory at the Antarctic

O values in ice and water samples from the Arctic and Antarctic, as well as the δ 13 C values of dissolved inorganic carbon in the water of the polar oceans. In addition, our laboratories offer the possibility [...] input) and changes in the supply of nutrient silicon and its use in polar and subpolar ocean regions (e.g. Southern Ocean, North Pacific) can be reconstructed on geological time scales. For the measurements [...] Clumped isotopes δ 13 C + δ 18 O (biog. carbonate, foraminifers) Option: clumped isotopes Changes in ocean circulation, nutrient content and deep water ventilation (δ 13 C) Hydrographic changes (δ 18 O, Δ47)
