A complex of sedimentological, geochemical, and micropaleontological methods was used to study and compare five new sediment cores along a submeridional transect from the middle to the north of the Norwegian Sea. A combined analysis of the distribution of ice-rafted debris, polar/subpolar foraminifera, calcium carbonate, organic carbon, and continuous geochemical scanning records revealed an alternation of Middle–Late Quaternary glacial and interglacial intervals over the last 260 000 years. In the Late Middle Pleistocene glaciation (MIS 6, 8), the supply of terrigenous material had a much greater influence on regional sedimentation than in the Late Pleistocene (MIS 2–4). Local (between the central and northern parts of the Norwegian Sea) differences in glacial and interglacial sedimentation are shown.
