Objective and goal
The goal of the study is to improve our understanding of the timing, geometry and magnitude of the Neogene and Quaternary erosion and uplift of the Russian and Norwegian parts of the Barents Sea and the Norwegian Sea. Particularly we will:
- Build regional models of the Plio-Pleistocene erosion/deposition for the three stages ~3.5-2.4 Ma, ~2.4-1.0 Ma, <1.0 Ma for the entire Barents Sea and the Norwegian Sea.
- Isostatic modeling
a. Calculate the isostatic response of erosion/deposition in 1.
b. Calculate the glacial isostatic response of the ice caps for the Barents Sea and Norwegian Sea.
- Evaluate the Neogene tectonic uplift
a. Based on post-glacial data from the Northern Scandes Dome, Svalbard and Novaya Zemlya
b. Based on progradation of the Molo Formation delta systems and modeling of transects over Helgeland Basin
- Evaluate the magnitude of the Neogene erosion phases for the Barents Sea and Norwegian Sea (with emphasis on the north-eastern part). We will use our improved understanding of the Neogene uplift to attempt to evaluate the amount of Paleogene uplift and erosion of the Barents Sea
- Determination of phases of uplift and erosion on Novaya Zemlya and Kara Sea
- Stress effects on faults caused by erosion
- Evaluate the development of permafrost
