      Seawater Mg:Ca and Sr:Ca ratios are biogeochemical parameters reflecting the Earth–ocean–atmosphere dynamic exchange of elements. The ratios’ dependence on the environment and organisms' biology facilitates their application ...
    • High‐resolution chronology of 24 000‐year long cores from two lakes in the Polar Urals, Russia, correlated with palaeomagnetic inclination records with a distinct event about 20 000 years ago 

      Haflidason, Haflidi; Brendryen, Jo; Eldegard, Reidun Fagerheim; Mangerud, Jan; Ólafsdóttir, Sædis; Regnéll, Carl; Svendsen, John Inge (Journal article; Peer reviewed, 2021)
      Based on radiocarbon dating, a tephra horizon, varve counts and palaeomagnetism, detailed age models covering the last ~24 k cal a bp, have been developed for the stratigraphy in the lakes Bolshoye Shchuchye and Maloye ...
    • Holocene multi-proxy environmental reconstruction from lake Hakluytvatnet, Amsterdamøya Island, Svalbard (79.5°N) 

      Gjerde, Marthe; Bakke, Jostein; D'Andrea, William J.; Balascio, Nicholas L.; Bradley, Raymond S.; Vasskog, Kristian; Ólafsdóttir, Sædis; Torgeir Opeland, Røthe; Perren, Bianka B.; Hormes, Anne (Journal article, 2018-03)
      High resolution proxy records of past climate are sparse in the Arctic due to low organic production that restricts the use of radiocarbon dating and challenging logistics that make data collection difficult. Here, we ...
    • Reconstruction of glacier variability from lake sediments reveals dynamic Holocene climate in Svalbard 

      Bilt, Willem van der; Bakke, Jostein; Vasskog, Kristian; D`Andrea, William; Bradley, Raymond S.; Ólafsdóttir, Sædis (Peer reviewed; Journal article, 2015-09-12)
      The Arctic is warming faster than anywhere else on Earth. Holocene proxy time-series are increasingly used to put this amplified response in perspective by understanding Arctic climate processes beyond the instrumental ...
