Deep Earth processes:
- What is the relationship between syn-rift crustal thinning and post-rift vertical movements? This appears to be much better understood in sedimentary basins (thermal subsidence, post-rift sedimentary load) than in the uplifted onshore areas (multiple models)
- What are the roles played by flexure of the lithosphere in response to its erosional unloading and sedimentary loading, 'dynamic impingement' of mantle plumes and/or mantle upwelling, and intraplate compressional stresses on long wavelength uplift? Detailed tomographic images of sub-lithospheric mantle beneath the Norwegian margin and Scandes mountains are required to constrain structural and material contrasts
- What is the relationship between inherited structures and post-rift vertical movements? Do contractional movements occur and are they localised on inherited structures?
- Does active faulting contribute to uplift and subsidence during the post-rift phase?
- What is the relationship between faulting and post-rift sediment transport patterns?
- What is the role played by magmatism during rifting and margin evolution?
- What is the relative contribution of mantle and crustal processes to topography development?
Surface processes:
- What is the relationship between (tectonic) uplift, palaeic surfaces and landscape types? What are their ages?
- How do erosion and uplift interact?
- What are the mechanisms of relief development through fluvial and glacial erosion?
- What are the ages, configuration and origin of the paleic surfaces?
- What is the configuration and development of the pre-Quaternary fluvial landscape?
- How does fluvial and glacial transport and deposition of erosion products to offshore areas occur?
Tasks in landform evolution:
- Mapping and dating of terrestrial pre-Quaternary landforms and sediments to reconstruct the pre-glacial landscape
- Mapping and dating of offshore erosion surfaces
- Offshore 3D seismic interpretation to constrain transport and depositional processes and patterns
- Chronological control and volume calculations of offshore sediments in an effort to establish a material balance between onshore erosion and offshore deposition
- Age, genesis, uplift and lateral movement of the different paleic surfaces
- Quantification of landform evolution and sediment fluxes to constrain Neogene uplift
- Modelling of fluvial incision in response to uplift and climate change during pre-Quaternary landscape evolution
- Modelling of glacial landscape development, including sub-glacial erosion on how glaciers exploit pre-existing topography
