| Summary: | A sediment core, collected from the western part of the continental slope of the Ross Sea at 2380 m water depth, records . 230events of the last two climatic cycles 250 kyr. A Th-based chronology was obtained and boundaries of the isotopeex stages were set assuming that biological productivity was enhanced during periods of less ice cover. Then, 230Th0, organicex carbon, biogenic silica and biogenic Ba distributions were compared to the glacial–interglacial stage boundaries and |
