摘要：
Based on sedimentological, isotope-geochemical, and micropaleontological parameters of bottom sediments of the AMK-5188 core, differences in the natural environment of the last interglacial of the Late Pleistocene (marine oxygen isotope substage 5e) and the Holocene in the Lofoten Basin of the Norwegian Sea were revealed. The local thermal optimum of the last interglacial was shifted to the second half of substage 5e similar to 124-115 ka and consisted of two short intervals separated by strong cooling similar to 122-120 ka. In the Early-Middle Holocene similar to 10(-3) ka, a long stable climate optimum was noted for the main identified parameters, and a short paleotemperature minimum occurred in the Late Holocene similar to 3-2 ka during the regional Neoglacial cooling.
