      Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Knutsen, Stig-Morten; Rydningen, Tom Arne (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, ...
    • Cenozoic uplift and erosion of the Norwegian Barents Shelf – A review 

      Lasabuda, Amando Putra Ersaid; Johansen, Nora; Laberg, Jan Sverre; Faleide, Jan Inge; Senger, Kim; Rydningen, Tom Arne; Patton, Henry; Knutsen, Stig-Morten; Hanssen, Alfred (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 ...
    • Contrasting Neogene–Quaternary continental margin evolution offshore mid-north Norway: Implications for source-to-sink systems 

      Olsen, Stine-Bjordal; Rydningen, Tom Arne; Laberg, Jan Sverre; Lasabuda, Amando P. E.; Knutsen, Stig Morten (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-22)
      The Neogene–Quaternary development of the ∼700 km long mid-Norwegian and Lofoten–Vesterålen continental margin is reconstructed using a dense grid of 2D seismic data and exploration wellbores. Overall, widespread ocean current-controlled contourite drifts built up along the whole margin segment from the mid-Miocene onwards (c. 11 Ma, Kai Formation). The onset (c. 8.8 Ma) of a large inner shelf ...
    • Depositional processes on the distal Scoresby Trough Mouth Fan (ODP Site 987): Implications for the Pleistocene evolution of the Scoresby Sund Sector of the Greenland Ice Sheet 

      Laberg, Jan Sverre; Rydningen, Tom Arne; Forwick, Matthias; Husum, Katrine (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-28)
      The investigation of trough mouth fans (TMFs), important paleoclimatic archives on mid- and high-latitude continental margins, has so far mainly been based on the integration of various types of acoustic data supplemented with short sediments cores. In consequence, sedimentological and chronological data about parts of TMFs deposited prior to the Last Glacial Maximum remains sparse. Here, we re-evaluate ...
    • An Early Neogene—Early Quaternary Contourite Drift System on the SW Barents Sea Continental Margin, Norwegian Arctic 

      Rydningen, Tom Arne; Høgseth, Gert; Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Safronova, Polina; Forwick, Matthias (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 ...
    • Geomorphology and development of a high-latitude channel system: the INBIS channel case (NW Barents Sea, Arctic) 

      Rui, L.; Rebesco, M.; Casamor, J.L.; Laberg, Jan Sverre; Rydningen, Tom Arne; Caburlotto, A.; Forwick, Matthias; Urgeles, R.; Accettella, D.; Lucchi, R. G.; Delbono, I.; Barsanti, M.; Demarte, M.; Ivaldi, R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-25)
      The INBIS (Interfan Bear Island and Storfjorden) channel system is a rare example of a deep-sea channel on a glaciated margin. The system is located between two trough mouth fans (TMFs) on the continental slope of the NW Barents Sea: the Bear Island and the Storfjorden–Kveithola TMFs. New bathymetric data in the upper part of this channel system show a series of gullies that incise the shelf break ...
    • Glacial history of the Åsgardfonna Ice Cap, NE Spitsbergen, since the last glaciation 

      Allaart, Lis; Schomacker, Anders; Larsen, Nicolaj K.; Nørmark, Egon; Rydningen, Tom Arne; Farnsworth, Wesley R.; Retelle, Michael J.; Brynjólfsson, Skafti; Forwick, Matthias; Kjellman, Sofia Elisabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-30)
      The response of glaciers and ice caps to past climate change provides important insight into how they will react to ongoing and future global warming. In Svalbard, the Holocene glacial history has been studied for many cirque and valley glaciers. However, little is known about how the larger ice caps in Svalbard responded to Late Glacial and Holocene climate changes. Here we use lake sediment cores ...
    • Glacigenic landforms and sediments in Store Koldewey Trough, NE Greenland – preliminary results 

      Olsen, Ingrid Leirvik; Forwick, Matthias; Laberg, Jan Sverre; Rydningen, Tom Arne; Husum, Katrine (Conference object; Konferansebidrag, 2018-04)
      The glaciation history of NE Greenland remains poorly constrained, resulting in conceptual and uncertain reconstructions of the configuration of the Greenland Ice Sheet during the Last Glacial Maximum (c. 24-19 ka BP), as well as the timing and the dynamics of the deglaciation. New studies suggests that the ice sheet in NE Greenland probably was more dynamic than previously thought, extending all ...
    • Hammerfest Basin Composite Tectono-Sedimentary Element 

      Henriksen, Erik; Kvamme, L.; Rydningen, Tom Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-21)
      The Hammerfest Basin is an E -W trending graben located between the Loppa High and the Finnmark Platform in the southern part of the Norwegian Barents Sea. Mainly siliciclastic strata of Carboniferous to Cenozoic age cover the Caledonian basement and have a total estimated thickness of 5-8 km. The basin evolved through several tectonic phases: the Carboniferous rifting, Late Jurassic rifting, the ...
    • A High Arctic inner shelf–fjord system from the Last Glacial Maximum to the present: Bessel Fjord and southwest Dove Bugt, northeastern Greenland 

      Zoller, Kevin Michael; Laberg, Jan Sverre; Rydningen, Tom Arne; Husum, Katrine; Forwick, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-10)
      The Greenland Ice Sheet (GrIS) responds rapidly to the present climate; therefore, its response to the predicted future warming is of concern. To learn more about the impact of future climatic warming on the ice sheet, decoding its behavior during past periods of warmer than present climate is important. However, due to the scarcity of marine studies reconstructing ice sheet conditions on the Northeast ...
    • Last glacial ice sheet dynamics offshore NE Greenland – a case study from Store Koldewey Trough 

      Olsen, Ingrid Leirvik; Rydningen, Tom Arne; Forwick, Matthias; Laberg, Jan Sverre; Husum, Katrine (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-04)
      The presence of a grounded Greenland Ice Sheet on the northeastern part of the Greenland continental shelf during the Last Glacial Maximum is supported by new swath bathymetry and high-resolution seismic data, supplemented with multi-proxy analyses of sediment gravity cores from Store Koldewey Trough. Subglacial till fills the trough, with an overlying drape of maximum 2.5 m thick glacier-proximal ...

      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 ...
    • Late Quaternary glacier and sea-ice history of northern Wijdefjorden, Svalbard 

      Allaart, Lis; Müller, Juliane; Schomacker, Anders; Rydningen, Tom Arne; Håkansson, Lena; Kjellman, Sofia Elisabeth; Mollenhauer, Gesine; Forwick, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-10)
      The deglaciation history and Holocene environmental evolution of northern Wijdefjorden, Svalbard, are reconstructed using sediment cores and acoustic data (multibeam swath bathymetry and sub‐bottom profiler data). Results reveal that the fjord mouth was deglaciated prior to 14.5±0.3 cal. ka BP and deglaciation occurred stepwise. Biomarker analyses show rapid variations in water temperature and sea ...
    • Late Weichselian and Holocene behavior of the Greenland Ice Sheet in the Kejser Franz Josef Fjord system, NE Greenland 

      Olsen, Ingrid Leirvik; Laberg, Jan Sverre; Forwick, Matthias; Rydningen, Tom Arne; Husum, Katrine (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-14)
      To better understand the past retreat patterns and chronologies of major marine-terminating outlet glaciers, the Late Weichselian and Holocene glacial history of a NE Greenland fjord system is reconstructed using new and previously published swath bathymetry and high-resolution seismic data, supplemented with multi-proxy analysis of sediment cores. The investigated area extends more than 190 km, ...
    • The marine-based NW Fennoscandian ice sheet: glacial and deglacial dynamics as reconstructed from submarine landforms 

      Rydningen, Tom Arne; Vorren, Tore Ola; Laberg, Jan Sverre; Kolstad, Vidar (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-03-16)
      The configuration of the marine-based NW Fennoscandian ice sheet during the Last Glacial Maximum (LGM) and deglaciation is reconstructed using detailed swath bathymetry and high-resolution seismic data. The investigated area covers about 10,000 km<sup>2</sup> of the continental shelf off Troms, northern Norway. Large scale morphology is characterized by cross-shelf troughs, coast-parallel troughs ...
    • A multi-source-to-sink system in a dynamic plate tectonic setting: the Cenozoic of the Barents Sea, Norwegian Arctic 

      Lasabuda, Amando P. E.; Chiarella, Domenico; Sømme, Tor Oftedal; Hanssen, Alfred; Laberg, Jan Sverre; Rydningen, Tom Arne; Patton, Henry (Conference object; Konferansebidrag, 2022)
      <p>When multiple source areas are located on a continuously moving plate margin relative to a sink, the signal propagation in the source-to-sink system may vary significantly in time and space. How fast and severe the impact of tectonics and climate is on sediment erosiontransfer-deposition in this dynamic setting is still not well understood. Similarly, how do we quantify the relative sediment ...
    • Paleobathymetric reconstructions of the SW Barents Seaway and their implications for Atlantic–Arctic ocean circulation 

      Lasabuda, Amando P. E.; Hanssen, Alfred; Laberg, Jan Sverre; Faleide, Jan Inge; Patton, Henry; Abdelmalak, Mohamed Mansour; Rydningen, Tom Arne; Kjølhamar, Bent (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-29)
      Unravelling past, large-scale ocean circulation patterns is crucial for deciphering the longterm global paleoclimate. Here we apply numerical modelling to reconstruct the detailed paleobathymetry-topography of the southwestern inlet of the Barents Seaway that presently connects the Atlantic and Arctic oceans. Subaerial topography was likely enough to block Atlantic Water from entering the Barents ...
    • Reviewing the Cenozoic Net Erosion of the Barents Sea Shelf 

      Lasabuda, Amando Putra Ersaid; Laberg, Jan Sverre; Knutsen, Stig-Morten; Rydningen, Tom Arne (Conference object; Konferansebidrag, 2019-01)
    • Seabed morphology and sedimentary processes on high-gradient trough mouth fans offshore Troms, northern Norway 

      Rydningen, Tom Arne; Laberg, Jan Sverre; Kolstad, Vidar (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-01)
      Trough mouth fans (TMF) situated at the mouths of formerly glaciated cross-shelf troughs are important paleoclimatic archives. Whereas the sedimentary processes of large, low-gradient TMFs have received considerable interest, little attention has been paid to the other end member of this landform class, i.e. TMFs with higher slope gradients. Detailed swath-bathymetric data and seismic profiles from ...
