Assessing linkages between ice sheet calving, subpolar gyre hydrography and deep water ventilation during the last glaciation
Rutledal, Sunniva (Master thesis, 2017-06-23)It is commonly postulated that ice sheet dynamics and freshwater perturbations in the North Atlantic were linked to disruptions in deep water circulation and North Atlantic cooling in the past. However, the exact nature ... -
A continuous tephrostratigraphic record from the Labrador Sea spanning the last 65 ka
Rutledal, Sunniva; Haflidason, Haflidi; Berben, Sarah Miche Patricia; Griem, Lisa; Jansen, Eystein (Journal article; Peer reviewed, 2020)Volcanic ash preserved in marine sediment sequences is key for independent synchronization of palaeoclimate records within and across different climate archives. Here we present a continuous tephrostratigraphic record from ... -
Tephra horizons identified in the western North Atlantic and Nordic Seas during the Last Glacial Period: Extending the marine tephra framework
Rutledal, Sunniva; Berben, Sarah Miche Patricia; Dokken, Trond Martin; Bilt, Willem van der; Cederstrøm, Jan Magne; Jansen, Eystein (Journal article; Peer reviewed, 2020)Geochemically distinct volcanic ash (tephra) deposits are increasingly acknowledged as a key geochronological tool to synchronize independent paleoclimate archives. Recent advances in the detection of invisible (crypto) ... -
Tephrochronology of the North Atlantic during the Last Glacial period – a paleoclimate synchronization tool
Rutledal, Sunniva (Doctoral thesis, 2021-04-09)During present time, the global climate is changing at a rapid pace. To understand the future consequences of these changes, studies of past abrupt climate change are essential. A natural analogue to the current climate ...
