| contents | Environmental changes in the surface and bottom water layers of the Ingøydjupet Basin and history of Atlantic water inflow to the southwestern Barents Sea during the last 16 ka are reconstructed on the base of planktic and benthic foraminiferal assemblages. A multiproxy study of sediment cores PSh-5159R and PSh-5159N, including AMS 14C dating, provides time resolution of about 200 years for the deglaciation period, 100 years for Holocene, and 25-50 years for the last 400 years. Stable polar conditions with sea ice on the surface were typical for the early deglaciation period. Unstable bottom settings and onset of ice rafting marked Oldest Dryas. Cold Atlantic water inflow increased notably during the Boiling-Allerod interstadial nearby the site location and then decreased during the Younger Dryas. Early Holocene was characterized by abrupt warming in the bottom and surface water layers, especially ~9.7-7.6 ka BP. Stable conditions prevailed during Middle Holocene. Remarkable changes in the sea-surface temperature and bottom environments occurred during last 2.5 cal. ka BP. |
