Lake Sediments Reveal Large Variations in Flood Frequency Over the Last 6,500 Years in South-Western Norway
Ekblom Johansson, Fanny Maria; Bakke, Jostein; Støren, Eivind Wilhelm Nagel; Paasche, Øyvind; Engeland, Kolbjørn; Arnaud, Fabien (Journal article; Peer reviewed, 2020)Lake sediments can retain imprints of past floods, enabling reconstructions that span well-beyond instrumental time series. Time series covering thousands of years can document the natural range of flood variability, which ... -
Late Glacial mountain glacier culmination in Arctic Norway prior to the Younger Dryas
Wittmeier, Hella Elisa; Schaefer, Joerg M.; Bakke, Jostein; Rupper, Summer; Paasche, Øyvind; Schwartz, Roseanne; Finkel, Robert C. (Journal article; Peer reviewed, 2020)Climate changes during the Late Glacial period (LG; 15-11 ka) as recorded in Greenland and Antarctic ice cores show a bipolar pattern. Between 14.5 ka and 13 ka ago, the northern latitudes experienced the Bølling/Allerød ... -
Long‑term demise of sub‑Antarctic glaciers modulated by the Southern Hemisphere Westerlies
Bakke, Jostein; Paasche, Øyvind; Schaefer, Joerg M.; Timmermann, Axel (Journal article; Peer reviewed, 2021)The accelerated melting of ice on the Antarctic Peninsula and islands in the sub-Antarctic suggests that the cryosphere is edging towards an irreversible tipping point. How unusual is this trend of ice loss within the frame ... -
New flood frequency estimates for the largest river in Norway based on the combination of short and long time series
Engeland, Kolbjørn; Aano, Anna; Steffensen, Ida Grøndahl; Støren, Eivind Wilhelm Nagel; Paasche, Øyvind (Journal article; Peer reviewed, 2020)The Glomma River is the largest in Norway, with a catchment area of 154 450 km2. People living near the shores of this river are frequently exposed to destructive floods that impair local cities and communities. Unfortunately, ... -
Paleoclimate changes inferred from stable isotopes and magnetic properties of organic-rich lake sediments in Arctic Norway
Janbu, Aina Dahlø; Paasche, Øyvind; Talbot, Michael R. (Peer reviewed; Journal article, 2011-03-22)Stable isotope measures in organic matter are frequently used as indicators of past climate change. Although such analyses can provide valuable information, there is considerable uncertainty associated with studies of ...
