Description:
A stable oxygen isotope stratigraphy for the last 150.000 yr is established in sedimentary cores from the central Fram Strait. Radiometric ages obtained by the U/Th method in one core provide an absolute time framework for the oxygen isotope stratigraphy. The oxygen isotope record from substage 5a in the central Fram Strait is represented by lighter oxygen isotope ratios than substage 5e. This probably reflects lower salinities of the uppermost water column due to intense melting of icebergs and/or the supply of meltwater from adjacent landmasses rather than higher sea surface temperatures.
