Reconstruction of Atlantic Water variability during the Holocene in the western Barents Sea
This paper is part of Diane Groot's doctoral thesis which is available in Munin at http://munin.uit.no/handle/10037/6744 The gravity core JM09-KA11-GC from 345m water depth on the western Barents Sea margin was investigated for down-core distribution patterns of benthic Foraminifera, stable iso...
