It has been argued that the infiltration and retention of meltwater within firn across the percolation zone of the Greenland ice sheet has the potential to buffer up to  ∼  3.6 mm of global sea-level rise (Harper et al., 2012). Despite evidence confirming active refreezing processes above the equilibrium line, their impact on runoff and proglacial discharge has yet to be assessed. Here, we compare ...

High-resolution swath bathymetry, TOPAS sub-bottom profiles and four gravity cores from the Brunt Basin, southeastern Weddell Sea in Antarctica, were analysed with the purpose of reconstructing the ice sheet dynamics since the last glacial. Data collection was carried out by the British Antarctic Survey (BAS) and data analyses were carried out in a collaboration between the Department of Geosciences ...

Structurally controlled, syn-rift, clastic depocentres are of economic interest as hydrocarbon reservoirs; understanding the structure of their bounding faults is of great relevance, e.g. in the assessment of fault-controlled hydrocarbon retention potential. Here we investigate the structure of the Dombjerg Fault Zone (Wollaston Forland, NE Greenland), a syn-rift border fault that juxtaposes syn-rift ...

The focus of this master thesis is to investigate the paleoenvironmental and paleoceanography during the last deglaciation in Leirdjupet, a small submarine trough in the southwestern Barents Sea. The lower half of the piston corer HH15-1303PC has been investigated for the distribution pattern of benthic foraminifera faunas, ice rafted debris (IRD), lithology and oxygen and carbon isotopes covering; ...

The metasediementary rocks of the Coastal Terrane in the Kaoko Belt (Namibia) and the meta-igneous rocks of the Punta del Este-Terrane in the Dom Feliciano Belt (Uruguay) both share one high-grade metamorphic event at approximately the same time of c. 650-630 Ma. Metamorphic conditions of this high-grade event were estimated in four samples from the Punta del Este Terrane and two samples from ...

In the light of rapidly diminishing sea ice cover in the Arctic during the present atmospheric warming, it is imperative to study the distribution of sea ice in the past in relation to rapid climate change. Here we focus on glacial millennial-scale climatic events (Dansgaard/Oeschger events) using the sea ice proxy IP25 in combination with phytoplankton proxy data and quantification of diatom species ...

On Uløya, an island located east of the Lyngen peninsula in northern Troms, Norway, four Caledonian nappes are exposed. These are from bottom to top: part of the Kalak Nappe Complex (KNC), the Vaddas, the Kåfjord and the Nordmannvik nappe. In the present study the geology of these nappes is described, macroscopic and microscopic deformation structures are analyzed, and phase equilibrium modeling is ...

This study focuses on Paleozoic and Mesozoic brittle faults and fractures found onshore and offshore in the northwestern areas of Finnmark, the Finnmark Platform, and the southwestern Barents Sea Margin. These structures have been mapped using software for mapping (ArcGIS 10.5 & Petrel 2013) and analyzing fault-fracture lineaments and faults from bathymetry, digital elevation models, satellite images, ...

2D seismic data have been analysed to study the Cenozoic pre-glacial sedimentary environment on the southwest Barents Sea margin and the Lofoten Basin. Based on a seismic stratigraphic analysis and correlation to previous work in the area, the pre-glacial seismic unit G0 has been subdivided into four. The four units have been described and discussed with regards to the geometry and internal seismic ...

Multi-proxy analyses of the giant piston core MD992301 (including lithostratigraphy, physical properties and XRF-scanning) and analyses of swath bathymetry data was integrated in order to reconstruct the glacial history and paleoenvironment of the distal parts of the INBIS channel, located between the distal Bear Island Trough Mouth Fan and Storfjorden Trough Mouth Fan. Based on the swath bathymetry ...
