Outline of Final Research Achievements |
We have analyzed sediment cores retrieved from the Bering Sea to reconstruct the glacial to deglacial changes in the ocean ventilation, particularly for the North Pacific Intermediate Water (NPIW). Source regions of the NPIW have switched from the Bering Sea during glaciation to the Okhotsk Sea during the Holocene. Millennial-scale oscillations of NPIW ventilation were suggested during the last deglacial period between 20,000 and 10,000 years ago.
