Abstract
A comparison of the new results on diatom micropaleontology with the available paleooceanological data on core PS1243-2 and global/regional paleoclimate archives made it possible to assume that neoglaciation in the central Norwegian-Greenland Basin near the Arctic front began no later than 4500 years ago. From this level, the Arctic front gradually approached the study area. There was a decrease in the influence of the mixed Arctic-Norwegian water, and the conditions on the surface became more contrasting, with an increase in signs of Arctic or North Atlantic (from the Norwegian Current) water. The moments of the greatest contrast are noted during short-term warmings of the Late Holocene.
