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 (Peer reviewed; Journal article, 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 ... -
The development of ocean currents and the response of the cryosphere on the Southwest Svalbard shelf over the Holocene
Devendra, Dhanushka; Łącka, Magdalena; Szymańska, Natalia; Szymczak-Żyła, Małgorzata; Krajewska, Magdalena; Weiner, Agnes; De Schepper, Stijn; Simon, Margit Hildegard; Zajączkowski, Marek (Peer reviewed; Journal article, 2023)While general trends in the inflow of Atlantic Water (AW) to the European Arctic over the present interglacial (the Holocene) are well known, regional changes in climate and the AW current and subsequent environmental ... -
ForCenS-LGM: a dataset of planktonic foraminifera species assemblage composition for the Last Glacial Maximum
Jonkers, Lukas; Mix, Alan; Voelker, Antje; Risebrobakken, Bjørg; Smart, Christopher W.; Ivanova, Elena; Arellano-Torres, Elsa; Eynaud, Frédérique; Naoufel, Haddam; Max, Lars; Rossignol, Linda; Simon, Margit Hildegard; Martins, Maria Virgínia Alves; Petró, Sandro; Caley, Thibaut; Dokken, Trond Martin; Howard, Will; Kucera, Michal (Peer reviewed; Journal article, 2024)Species assemblage composition of marine microfossils offers the possibility to investigate ecological and climatological change on time scales inaccessible using conventional observations. Planktonic foraminifera - ... -
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 Miche Patricia; 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 ... -
A multi-decadal record of oceanographic changes of the past ~165 years (1850-2015 AD) from Northwest of Iceland
Simon, Margit Hildegard; Muschitiello, Francesco; Tisserand, Amandine Aline; Olsen, Are; Moros, Matthias; Perner, Kerstin; Bårdsnes, Siv Tone; Dokken, Trond Martin; Jansen, Eystein (Peer reviewed; Journal article, 2020)Extending oceanographic data beyond the instrumental period is highly needed to better characterize and understand multi-decadal to centennial natural ocean variability. Here, a stable isotope record at unprecedented ... -
Recommended centrifuge method: Specific grain size separation in the <63 µm fraction of marine sediments
Pryor, E.J.; Tangunan, D.; van der Lubbe, der; Simon, Margit Hildegard; Hall, I.R. (Peer reviewed; Journal article, 2024)The isolation of specific grain size classes of lithogenic samples and biogenic carbonate from the <63 µm fraction (i.e. clay and silt) of marine sediment is often a prerequisite to further pre-treatments and/or analytical ... -
Sequential extraction procedure to obtain the composition of terrigenous detritus in marine sediments
Simon, Margit Hildegard; Babin, Daniel P.; Goldstein, Steven L.; Cai, Merry Yue; Liu, Tanzhuo; Han, Xibin; Haws, Anne A.; Johns, Matthew; Lear, Caroline H.; Hemming, Sidney R. (Peer reviewed; Journal article, 2020)The geochemical and isotopic composition of terrigenous clays from marine sediments can provide important information on the sources and pathways of sediments. In order to extract the detrital signal from bulk marine ...
