A common aim of the IPY projects, SciencePub (IPY39) and WARMPAST (IPY786), is to increase our knowledge of the consequences of climate warming in the Arctic by studying past climate change. The present climate in the Arctic shows signs of rapid change with decreasing sea ice cover and increasing temperature of the Atlantic Water. The implications of this warming are highly uncertain, as modelling experiments projecting temperatures for the next 100 years show a large scatter at high northern latitudes. Therefore it is crucial to obtain long records of climate changes in the past to assess the natural limits of Arctic climate. In order to obtain time series on sea ice, temperature, salinity etc in the water masses from the past when instrumental measurements was not in use we study fossil micro-fauna, planktic foraminifera, in the sediments. Hence, another necessary aim is to improve the proxies of ocean temperature by achieving high quality modern analogue data and develop new palaeoclimatic proxies. During SciencePub cruises in 2007 and 2008 new modern analogue data on planktic foraminifera were collected. Undisturbed sediment samples were taken by box and multi corer together with CTD measurements across the Fram Strait and Norwegian-Greenland Sea in order to cover the widest possible oceanographic range of the polar North Atlantic. In addition, long sediment cores covering the last glacial-interglacial cycle were obtained. Results show how the new modern analogue data clearly reflect various water masses in the study area that previously was sparsely covered. Another implication is found when including temperatures of intermediate water masses; the temperatures reach lower values, and it is possible to obtain new detailed sea surface temperature records below 5°C.
