Popis:	X-ray Fluorescence Analysis with Synchrotron Radiation (SR XFA) was used to study, at a high-resolution (� 200 yr), the behavior of elements in an 80 kyr core record from the Okhotsk Sea. We measured biogenic Ba (BaBio), biogenic carbonate, and organic carbon as bio production indicators, elements that record the Amur terrigenous input, and Mn as signature of water ventilation and redox conditions at the sediment/water interface. The Okhotsk Sea in last glacial time responded to abrupt warm spells in the Atlantic and Greenland. Bio production in the Okhotsk Sea increased dramatically during warm D/O events and decreased during cold and dry H-events. r 2005 Elsevier B.V. All rights reserved.
