Outline of Final Research Achievements

TEX86 analysis indicated that sea surface temperature (SST) decreased from 12,000 years ago to 3,000 years ago and increased afterward off Wilkes Land in the Southern Ocean. In the Chukchi Sea of the Arctic, SST increased since 9,000 years ago. Both areas showed significant millennial-scale SST variability. In the Chukchi Sea core, the chlorite/illite ratio showed higher values in the middle Holocene, suggesting the intensified Bering Strait inflow. The Quartz/feldspar ratios showed a decreasing trend, suggesting a decline of the Beaufort Gyre circulation since 9,000 years ago.
