we determine the δ 18 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 [...] δ 18 O (seawater) Capturing modern hydrological processes in the ocean (T,S, stratification); T-S-signatures of different water masses MAT253 + EA IsoLink CN (is in acquisition; available from autumn [...] 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, pure diatom-,

We combine long term observations from ground stations and innovative measurements from airborne platforms [...] 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 research station Neumayer

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 heat, moisture, momentum and [...] 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 and in the availability of

The objectives of the project are to: (i) Reconstruct (a) mean interglacial temperatures at the southern [...] Meyer Funding: Leverhulme 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 [...] is 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
