Atlantic inflow and low sea-ice cover in the Nordic Seas promoted Fennoscandian Ice Sheet growth during the Last Glacial Maximum
Simon, Margit Hildegard; Rutledal, Sunniva; Menviel, Laurie; Zolles, Tobias; Haflidason, Haflidi; Born, Andreas; Berben, Sarah Miche Patricia; Dokken, Trond Martin (Journal article; Peer reviewed, 2023)The Atlantic water inflow into the Nordic Seas has proven difficult to reconstruct for the Last Glacial Maximum. At that time, the Fennoscandian Ice Sheet grew potentially to its maximum extent. Sea-ice free conditions in ... -
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 ... -
Evidence of Isotopic Fractionation During Vapor Exchange Between the Atmosphere and the Snow Surface in Greenland
Madsen, M.V.; Steen‐Larsen, H.C.; Hörhold, M.; Box, J.; Berben, Sarah Miche Patricia; Capron, E.; Faber, Anne-Katrine; Hubbard, Alun Lloyd; Jensen, Mari Fjalstad; Jones, T.R.; Kipfstuhl, S.; Koldtoft, I.; Pillar, H.R.; Vaughn, B.H.; Vladimirova, D.; Dahl‐Jensen, D. (Peer reviewed; Journal article, 2019-03)Several recent studies from both Greenland and Antarctica have reported significant changes in the water isotopic composition of near‐surface snow between precipitation events. These changes have been linked to isotopic ... -
A first chronology for the East Greenland Ice-core Project (EGRIP) over the Holocene and last glacial termination
Mojtabavi, Seyedhamidreza; Wilhelms, Frank; Cook, Eliza; Davies, Siwan M.; Sinnl, Giulia; Skov Jensen, Mathias; Dahl-Jensen, Dorthe; Svensson, Anders; Vinther, Bo; Kipfstuhl, Sepp; Jones, Gwydion; Karlsson, Nanna B.; Henrique Faria, Sergio; Gkinis, Vasileios; Astrid Kjær, Helle; Erhardt, Tobias; Berben, Sarah Miche Patricia; Nisancioglu, Kerim Hestnes; Koldtoft, Iben; Olander Rasmussen, Sune (Journal article; Peer reviewed, 2020)This paper provides the first chronology for the deep ice core from the East Greenland Ice-core Project (EGRIP) over the Holocene and the late last glacial period. We rely mainly on volcanic events and common peak patterns ... -
Insolation and Glacial Meltwater Influence on Sea‐Ice and Circulation Variability in the Northeastern Labrador Sea During the Last Glacial Period
Griem, Lisa; Voelker, Antje H.L.; Berben, Sarah Miche Patricia; Dokken, Trond Martin; Jansen, Eystein (Journal article; Peer reviewed, 2019)The variable amounts of ice rafted debris (IRD) and foraminifers in North Atlantic sediments are related to the abrupt, millennial‐scale alteration from Greenland stadials to interstadials during the last glacial period ... -
Late Holocene canyon-carving floods in northern Iceland were smaller than previously reported
Bilt, Willem Godert Maria van der; Barr, Iestyn D.; Berben, Sarah Miche Patricia; hennekam, rick; Lane, Timothy P.; Adamson, Kathryn; Bakke, Jostein (Journal article; Peer reviewed, 2021)Catastrophic floods have formed deep bedrock canyons on Earth, but the relationship between peak discharge and bedrock erosion is not clearly understood. This hinders efforts to use geological evidence of these cataclysmic ... -
A late-Holocene multi-proxy record from the northern Norwegian margin: Temperature and salinity variability
Berben, Sarah Miche Patricia; Husum, Katrine; Sørensen, Steffen Aagaard (Journal article, 2016)To elucidate the natural variability of Atlantic and Coastal water, a late-Holocene multi-proxy analysis is performed on a marine sediment core from the northern Norwegian margin. This includes planktic foraminiferal fauna ... -
Rapid Tephra Identification in Geological Archives With Computed Tomography: Experimental Results and Natural Applications
Van Der Bilt, Willem; Cederstrøm, Jan Magne; Støren, Eivind Wilhelm Nagel; Berben, Sarah Miche Patricia; Rutledal, Sunniva (Journal article; Peer reviewed, 2021)Volcanic ash (tephra) horizons represent powerful chronological and stratigraphic markers: rapid and widespread deposition allows for correlation of geological records in time and space. Recent analytical advances enable ... -
Sea ice variability in the southern Norwegian Sea during glacial Dansgaard-Oeschger climate cycles
Sadatzki, Henrik; Dokken, Trond Martin; Berben, Sarah Miche Patricia; Muschitiello, Francesco; Stein, Ruediger; Fahl, Kirsten; Menviel, Laurie; Timmermann, Axel; Jansen, Eystein (Peer reviewed; Journal article, 2019-03-06)The last glacial period was marked by pronounced millennial-scale variability in ocean circulation and global climate. Shifts in sea ice cover within the Nordic Seas are believed to have amplified the glacial climate ... -
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) ...
