Clumped isotope thermometry in bivalve shells: a tool for reconstructing seasonal upwelling
Caldarescu, Diana Elena; Sadatzki, Henrik; Dahl, Carin Andersson; Schäfer, Priska; Fortunato, Helena; Meckler, Anna Nele (Journal article; Peer reviewed, 2021)Carbonate clumped isotope thermometry is a powerful tool for reconstructing paleotemperature and paleosalinity. Despite its broad application in biotic and abiotic materials, its use in paleoclimate studies has been limited ... -
Independent tephrochronological evidence for rapid and synchronous oceanic and atmospheric temperature rises over the Greenland stadial-interstadial transitions between ca. 32 and 40 ka b2k
Berben, Sarah M.P.; Dokken, Trond Martin; Abbott, Peter M.; Cook, Eliza; Sadatzki, Henrik; Simon, Margit Hildegard; Jansen, Eystein (Journal article; Peer reviewed, 2020)Understanding the dynamics that drove past abrupt climate changes, such as the Dansgaard-Oeschger (DO) events, depends on combined proxy evidence from disparate archives. To identify leads, lags and synchronicity between ... -
The potential of sedimentary ancient DNA for reconstructingpast sea ice evolution
De Schepper, Stijn; Ray, Jessica Louise; Skaar, Katrine Sandnes; Sadatzki, Henrik; Ijaz, Umer Zeeshan; Stein, Ruediger; Larsen, Aud (Peer reviewed; Journal article, 2019-06-24)Sea ice is a crucial component of the Arctic climate system, yet the tools to document the evolution of sea ice conditions onhistorical and geological time scales are few and have limitations. Such records are essential ... -
Sea ice variability in the Nordic Seas over Dansgaard–Oeschger climate cycles during the last glacial – A biomarker approach
Sadatzki, Henrik (Doctoral thesis, 2019-02-15)The Arctic sea ice cover is in fast transition. Resolving past sea ice fluctuations and its link with abrupt climate change might be key for a better understanding of yet unknown climatic consequences of future Arctic sea ... -
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 ... -
A spatio-temporal reconstruction of sea-surface temperatures in the North Atlantic during Dansgaard-Oeschger events 5–8
Jensen, Mari Fjalstad; Nummelin, Aleksi; Nielsen, Søren B.; Sadatzki, Henrik; Sessford, Evangeline; Risebrobakken, Bjørg; Andersson, Carin; Voelker, Antje; Roberts, William H. G.; Born, Andreas (Journal article, 2017-08-24)Here we establish a spatio-temporal evolution of the sea-surface temperatures in the North Atlantic over Dansgaard Oeschger (DO) events 5–8 (c. 30–40 ka) using the proxy surrogate reconstruction method. Proxy data suggest ...
