  • Late Quaternary tephra stratigraphy and paleoenvironmental reconstruction based on lake sediments from North and Northeast Iceland 

    Bender, Emma Marie (Mastergradsoppgave; Master thesis, 2020-07-12)
    Due to Iceland’s position in the middle of the North Atlantic, the island is highly sensitive to oceanic and atmospheric fluctuations, which lead to changes in the environment. These fluctuating environmental conditions in addition to Iceland’s high volcanic activity make it a strategic study area for paleoenvironmental and tephra studies. Lake sediments contain information about such past climate ...

  • Neoglacial plateau ice cap behaviour in Central Spitsbergen constrained by subglacially preserved vegetation. 

    Roche, Amélie (Mastergradsoppgave; Master thesis, 2021-06-15)
    Cold-based glacial ice is well known to preserve underlying landforms produced by earlier processes but can also preserve pre-existing organic material and vegetated ground. With current rapid climate warming, overall glacier retreat in the Arctic is exposing formerly ice-buried in situ vegetation at the margin of cold-based ice bodies. Radiocarbon dating of this vegetation constrains the timing of ...

  • Rapid temperature rise may have triggered glacier surges all over Svalbard 

    Schytt Holmlund, Erik (Mastergradsoppgave; Master thesis, 2020-05-04)
    Observational and geomorphological records suggest that most glaciers on Svalbard reached their maximum Little Ice Age extents by means of surging. Furthermore, it seems to have happened within just a few decades, suggesting that the rapid concurrent changes in climate might have triggered this widespread surging. The specific precipitation and temperature range of Svalbard seems optimal for glacier ...
