Despite the intensive studies of the Okhotsk Sea paleoceanography during the last 30 years, its southeastern part remains poorly studied compared to other parts. However, southeastern sea segment seems present extremely important area for investigation of the northwestern Pacific paleoceanography and evolution of the Kamchatka Peninsula glaciation in the past. When the southward flowing East Kamchatka Current, main current of NW Pacific, passes the peninsula, a significant part of its water turns and enters the Sea of Okhotsk and northward moved as West Kamchatka Current. According to paleogeographical investigation, the currently existed mountain-valley glaciers of Kamchatka significantly increased in volume and space and extended beyond the coastline during glaciations, dumping icebergs into the sea from the eastern and southwestern sides of Kamchatka peninsula. Probability of the episodic impact of iceberg discharges from southwestern Kamchatka into the southeastern Okhotsk Sea during glaciations was earlier suggested by Sakamoto and Nurnberg. Here we provide new isotope-geochemical, lithological and productivity results from the southeastern core 9-1 and overview earlier published similar data from seven sediment cores, recovered in the other parts of sea and one from the northwestern Pacific. Comparison of these data allow to analyzed spatial changes of the sea ice formation and periodic iceberg discharges from Kamchatka into the sea and clarify evolution of the North Pacific Intermediate water and possible origin behind them during global climate change. Deviation of δ¹⁸O of benthic foraminifera Uvigerina spp. of used cores (δ¹⁸OUv) from benthic LS16 stack show millennium scale variability of North Pacific Intermediate water formation. Deviation of δ¹⁸O of planktic foraminifera N. pachyderma(s.) of used cores (δ¹⁸ONp) from benthic LS16 stack provide sequence of millennium scale episodically iceberg discharge from Kamchatka into the sea, nearly synchronously with enhancement of intermediate water formation. The lithological and productivity parameters of sediment from southeastern cores markedly differ from ones from the western and central parts during last glaciation and were punctuated by abrupt and large IRD rises at the millennial scale over the relative warm Marine Isotope Stages 3.
