    Sammanfattning : This thesis concerns the history of paleoclimatology in the postwar period. It follows the trajectory of two climate proxy records – ice cores and deep-sea cores – in the North Atlantic region, from their emergence as scientific objects in the 1940s to their incorporation into Earth System Science in the 1980s.

  3. 2. Late Quaternary Biostratigraphy and Paleoceanography of the central Arctic Ocean

    Sammanfattning : The central Arctic Ocean is one of the least explored deep sea regions and long biostratigraphic sediment records are sparse. The main focus of this thesis is the Arctic Ocean foraminiferal record and its application to reconstruct paleoceanographic variations and summer sea ice cover changes between late Quaternary interglacial periods.
