The Cenozoic era of the Barents Sea, Norwegian Arctic: A forward modelling of basin and landscape dynamics and implications for ocean circulation between the Atlantic and the Arctic

Abstract: In this talk, we will explore a near North Pole region called the Barents Sea in the Norwegian Arctic and its evolution throughout its Cenozoic era (c. 66 Ma). The geological history shows a complex interplay between tectonic, climatic and surface processes. However, datasets are limited and sparse in exploring this frontier area. What did the actual paleotopography look like during the onset of Northern Hemisphere Glaciation (c. 2.7 Ma)? How was the corresponding sediment routing from the source to the sink area? Can we constrain the oceanic basin configuration of an ultra-slow seafloor spreading in a magma-poor setting with a sharp and steep continental margin? Unlike the Fram Strait Gateway where the scientific community has largely reached a consensus on when it was opened (c. 17 Ma), what was the timing of the opening of the Barents Seaway? We will explore different factors, parameters and scenarios in reconstructing basin-fill stratigraphy and landscape evolution of the Arctic Barents Shelf and their implications for the ocean circulation between the Atlantic and Arctic oceans and the onset of Northern Hemisphere Glaciation. This project is part of the Marie Skłodowska-Curie Actions (MSCA) international mobility fellowship at the University of Sydney and the University of Oslo, funded by the European Union and the Research Council of Norway.

ANU Research School of Earth Sciences school seminar

Series comments: The ANU Research School of Earth Sciences seminar series regularly features academics, students, and researchers from Australia and around the world to present topics covering the entire range of earth sciences.

The seminars are held in the Jaeger 1 Seminar Room at RSES on Thursdays at 3 pm and also broadcast on zoom ( ID: 843-2801-3439, lightly protected via a password "jaeger" ). They are open to the ANU community and public. Talks will generally be made available on the RSES Seminar website in the days following the seminar.
