Glacigenic sedimentation pulses triggered postglacial gas hydrate dissociation
Karstens, Jens; Haflidason, Haflidi; Becker, Lukas W.M.; Berndt, Christian; Rüpke, Lars; Planke, Sverre; Liebetrau, Volker; Schmidt, Markus; Mienert, Jürgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-12)Large amounts of methane are stored in continental margins as gas hydrates. They are stable under high pressure and low, but react sensitively to environmental changes. Bottom water temperature and sea level changes were considered as main contributors to gas hydrate dynamics after the last glaciation. However, here we show with numerical simulations that pulses of increased sedimentation dominantly ... -
An updated Weichselian chronostratigraphic framework of the Kongsfjorden Trough Mouth Fan and its implications for the glacial history of Svalbard
Wiberg, Daniel Hesjedal; Haflidason, Haflidi; Laberg, Jan Sverre (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-02)The Arctic is a climate-sensitive area, responding rapidly to present changes, but for the past changes, the recordis still incomplete. Forinstance, theWeichselian glacial historyof the Svalbard–Barents Sea Ice Sheet (SBIS) haslargely been reconstructed based on studies of the fragmentary Spitsbergen terrestrial and shelf records. However, the sediments removed from the land and shelf areas during ...
