EGU2011-4204-1 The Russian German Cooperation in polar marine science has a long tradition. Since the last decade of the last century, there is a continous joint effort for geoscientific studies in the arctic and subarctic Far East. The new initiative of KALMAR II will concentrate on the complex geosystem of the Kurile-Kamchatka-Aleutean arc including the adjacent regions of the arctic Bering Sea and the NW Pacific. This giant and unique natural laboratory will allow the study of interactions and fluxes between the asthenosphere, the lithosphere, the hydrosphere, the cryosphere, and the atmosphere in order to provide detailed insights into natural risks (volcanic eruptions, tsunamis) and regional dynamics of the climate impacting on the global system. The envisaged integrated investigation will built upon the existing network of scientists from both countries who studied geodynamic and volcanologic as well paleoceanographic and paleoclimatic issues successfully in the past in the Far East. Two main research foci, ocean and climate dynamics as well as volcanisms and geodynamics, form the scientific backbone of the new KALMAR II initiative which will comprise in total five interlinked subprojects: Two subprojects will focus on the paleoclimatic and paleoceanographic evolution of this arctic region in relation to the development of the NW Pacific on millennial and decadal as well as seasonal times scales. This approach will test existing hypothesis with respect to water mass structure and water mass exchange through the Bering Strait, intermediate water mass formation, which, until know, is still not understood, marine productivity and their impact on the CO2 cycle, the glaciation history of Kamchatka and the continental oceanic (arctic) teleconnection between Atlantic and Pacific. The closely linked terrestrial subproject will study the marine influenced arctic region of Northern Kamchatka focusing on the geomorphologic and paleoclimatic evolution within the context of the northern hemisphere climate.
