Crevasses on Svalbard Glaciers: Distribution and Dynamic Controls
(Master thesis, 2015-05-31)Crevasses play a key role in understanding a wide range of glaciological processes, but the current understanding is mainly based on a few key studies. Recent years, studies on crevasse formation have been motivated by the ... -
Crustal structure and evolution of the Arctic Caledonides: Results fromcontrolled-source seismology
(Peer reviewed; Journal article, 2017-10)The continuation of the Caledonides into the Barents Sea has long been a subject of discussion, and two major orientations of the Caledonian deformation fronts have been suggested: NNW-SSE striking and NE-SW striking. A ... -
The deglaciation of Kongsfjorden, Svalbard —based on surface exposure dating of glacial erratics and Quaternary geological mapping of Blomstrandhalvøya
(Master thesis, 2016-05-27)Surface exposure dating via 10Be cosmogenic nuclide dating is used, alongside Quaternary geological mapping of landforms and sediments, to reconstruct the course of deglaciation following the Late Weichselian Glacial Maximum ... -
Holocene multi-proxy environmental reconstruction from lake Hakluytvatnet, Amsterdamøya Island, Svalbard (79.5°N)
(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
(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 ... -
Sedimentology and palynology of the Lower Cretaceous succession of central Spitsbergen: integration of subsurface and outcrop data
(Peer reviewed; Journal article, 2019-06-27)The Lower Cretaceous succession in Svalbard is commonly considered as an important analogue to age-equivalent strata on the Barents Shelf which are sporadically targeted by exploration wells. In this study, the stratigraphic ... -
Sedimentology of the Aspelintoppen Formation (Eocene-Oligocene), Brogniartfjella, Svalbard
(Master thesis, 2014-12-09)The following study investigate the vertical changes in fluvial channel and interchannel geometry and facies architecture of the Aspelintoppen Formation in the Cenozoic Central Basin on Svalbard. Sedimentary structures was ... -
A study of the ichnology, lithology and reservoir quality of the Palaeogene Grumantbyen Formation on Svalbard
(Master thesis, 2016-11-10)The Palaeogene Grumantbyen Formation is one of the least understood formations in the geology of Svalbard. The objective of this thesis was to get a better understanding of the sedimentological development and depositional ... -
Time-lapse techniques for surface velocity, front position and calving rate measurement of a fast-flowing tidewater glacier in Svalbard
(Master thesis, 2015-05-31)Calving is the mechanical loss of icebergs from tidewater glaciers, responsible for 70% of the annual transfer of mass from the cryosphere to the ocean (van der Veen 1998a, 2002). To be able to correctly predict future ...
