Cenozoic Erosion of the Barents Sea Shelf, Norwegian Arctic: A Review
(Conference object; Konferansebidrag, 2018-12)The circum North Atlantic-Arctic continental margin and adjacent land areas have experienced several episodes of uplift and erosion during the Cenozoic. A series of efforts quantifying this erosion for the Barents Sea shelf, where the Arctic shelf is at its widest and deepest have been done since the early 90’s using different methods. As the seismic and well database have expanded considerably, ... -
The Cenozoic evolution and sedimentary successions of the southwestern Eurasia Basin and the northern Svalbard/Barents Sea continental margin
(Conference object; Konferansebidrag, 2017)<p>The geologic history of the SW Eurasian Basin and the northern Svalbard/Barents Sea continental margin started in Late Cretaceous / early Tertiary. Since about 50 Ma seafloor spreading has been active in the Eurasian Basin splitting off the Lomonosov Ridge from the northern Eurasian Shelf. Since Miocene, rifting and seafloor spreading have been also established in between NE Greenland and Svalbard, ... -
The Cenozoic pre-glacial tectono-sedimentary development of the western Barents Sea margin: implications for uplift and erosion of the sediment source areas
(Conference object; Konferansebidrag, 2017)<p>The Cenozoic development of the western Barents Sea continental margin is strongly related to the rifting and seafloor spreading between Norway and Greenland. The margin is characterized by a series of highs and basins that formed as part of the development of a mega-transform zone. To the north, the Spitsbergen Fold and Thrust Belt and the Eocene clinoform development in the Central Basin that ... -

Cenozoic tectonosedimentary development and erosion estimates for the Barents Sea continental margin, Norwegian Arctic
(Doctoral thesis; Doktorgradsavhandling, 2018-04-26)The Barents Sea shelf has been experienced extensive uplift and erosion in the Cenozoic. However, the pre-glacial erosion has been so far less constrained in comparison to the glacial erosion. This paper aims to better understand the early–middle Cenozoic erosion in the western Barents Sea and the late Cenozoic erosion in the northern Barents Sea by using the mass-balance approach. The study utilizes ... -
Cenozoic tectonostratigraphy and pre-glacial erosion: A mass-balance study of the northwestern Barents Sea margin
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-26)<p>The evolution of the northwestern Barents Sea continental margin, part of a NW-SE trending mega shear zone, has been reconstructed in order to quantify the sedimentation and erosion affecting this area during and after its formation in the Paleogene–Neogene. This development was closely related to the sea-floor opening of the Norwegian-Greenland Sea. Our study incorporated 2D seismic data, well ... -
Cenozoic uplift and erosion of the Norwegian Barents Shelf – A review
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-23)Uplift and erosion are complex phenomena in terms of their governing processes, precise timing and exact magnitude. The intricate relationship between different geodynamic processes leading to uplift may increase uncertainties in estimating spatial and temporal patterns. Sediment distribution from uplifted (and eroded) topography and the corresponding paleoenvironmental reconstructions require ... -
An Early Neogene—Early Quaternary Contourite Drift System on the SW Barents Sea Continental Margin, Norwegian Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-30)The onset and evolution of the middle to late Cenozoic “icehouse” world was influenced by the development of the global ocean circulation linking the Norwegian–Greenland Sea-Arctic Ocean to the Atlantic Ocean. The evolution of the early Neogene to early Quaternary Bjørnøyrenna Drift, located at the SW Barents Sea continental margin, shed new light on this important hydrological event. By analyzing ... -
The Early to Middle Cenozoic Paleoenvironment and Erosion Estimates for the northwestern Barents Sea
(Conference object; Konferansebidrag, 2017)<p>The northwestern Barents Sea continental margin is a structurally complex area characterized by a series of basins and highs. It’s Cenozoic development was influenced by: 1) the formation of the Spitsbergen fold-andthrust belt towards the north and a pull-apart basin, the Vestbakken Volcanic Province, to the south, and 2) the subsequent rifting and opening of the Fram Strait, the deep-water gateway ... -
Early to middle Cenozoic paleoenvironment and erosion estimates of the southwestern Barents Sea: Insights from a regional mass-balance approach
(Journal article; Tidsskriftartikkel, 2018-06-02)The Cenozoic pre-glacial development of the southwestern Barents Sea is discussed, with focus on the early to middle Cenozoic net erosion that was poorly constrained. From 2D and 3D seismic mapping, the western Barents Sea continental margin development shows a complex history of structural configuration of highs and basins related to the Greenland and Eurasian plate movement and subsequent seafloor ... -
Late Cenozoic erosion estimates for the northern Barents Sea: Quantifying glacial sediment input to the Arctic Ocean
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-14)A compilation of seismic data has been used to characterize the Neogene – Quaternary sedimentary succession of the northwestern Barents Sea continental margin to better understand the paleoenvironmental evolution and the sedimentary processes involved. The Neogene strata are dominated by contourites related to the ocean circulation established from the opening of the Fram Strait connecting the ... -

Linking tectonostratigraphy and denudation history: insights from a mass balance approach
(Conference object; Konferansebidrag, 2017)<p>The offshore deep-sea stratigraphy provides the archive for reconstructing the paleoenvironment of the surrounding land and continental shelf areas. Mapping of seismic reflections as well as borehole correlation may identify the processes and timing of basin infilling. Regional and local tectonic events will be linked to other controlling factors in defining the structural configuration in order ... -
