My research currently focuses on high-resolution geochemical and sedimentological investigations in coastal near settings of the Nordic Seas and the Arctic Ocean. The published concepts for assessing recent organic sedimentation processes, the reconstruction of Late Quaternary paleoproductivity changes and terrestrial organic matter input, as well as the modeling of quality and quantity of Tertiary source rocks and evaluating active and passive seepages of gaseous hydrocarbons in polar coastal environments have provided new insights into the carbon cycle of high northern latitudes.

My main interests focus on glacial geology, Late Pleistocene stratigraphy, climate change and sedimentary processes in northern regions. This includes projects both in the terrestrial and in the marine fjord and lake environments. Projects:
Norpast 2: Past Climate of The Norwegian Region. My contribution concerns deglaciation history and environmental changes deduced from acoustic data and sedimentary cores in Nordfjord, W Norway.
SEDITRANS: Past and currents valley-to-fjord sediment transport- processes and products, western Norway. My scientific input concerns the fjord and lake sedimentary sub-systems (swath bathymetry, acoustic data and sedimentary cores).
GlaciPet: Ice ages: subsidence, uplift and tilting of traps – the influence on petroleum system. My input concerns the late Pleistocene stratigraphy and glacial history based on terrestrial fieldwork in NW Russia.
ICG: International Centre of Geohazard: Landslides in soft clay slopes. My input is to deduce spatial and stratigraphic (chronological) extent of Holocene submarine slides along the coastal zone of Trondheimsfjorden and to understand the processes and factors that have triggered these events.

My research is focused on controlling factors and mechanisms of denudative slope processes and fluvial processes, sediment budgets, and relief development in cold environments. I finished my PhD with a topic on sediment transfers and relief development in East Iceland at the Institute of Geography at the Martin-Luther University of Halle-Wittenberg in Germany (1996-1999). After my PhD time I continued and extended my process and sediment budget oriented studies with additional study sites in Iceland, Swedish Lapland and Finnish Lapland. From 1999 until my start at NGU in 2004 I have been Post-Doc and Visiting Scientist at the Department of Earth Sciences, Uppsala University, Sweden, and at the Natural Research Centre of North-western Iceland. During my time at NGU I have extended my investigations by adding Norwegian study sites. Research is currently carried out within the project Source-to-Sink-Fluxes in Cold Environments. I am interested in the integration of geo-, bio- and social systems within landscape studies. Proposals related to SEDIFLUX. I am Chair of ESF SEDIFLUX and IAG/AIG SEDIBUD. I participate with contributions on process geomorphology in the projects SciencePub and SEDITRANS.

Dinoflagellate cysts (dinocysts) are organic resting spores of a plankton group inhabiting the photic zone of the marine realm and the coastal region in particular.

My research applies dinocyst analysis as a method to understand sedimentological processes, hydrography and climates and to differentiate between glacial, deglacial and interglacial periods. Most of my work focuses on arctic environments.

My research are on the interactions between glacial-/post-glacial processes, Quaternary glaciations and landscape development. Most of my work concerns the Scandinavian shield and mountain areas. Current research topics include: 

• Qualitative and quantitative research on fjord development (SEDITRANS)
• Pre-Quaternary weathering, drainage patterns and landscape development (GEOS)
• Reconstructions of the Fennoscandian ice sheets, including ice age build-up

To reach these research objectives I use a variety of tools including; mapping using remote sensing data, GIS analysis, morpho- and lithostratigraphy, terrestrial cosmogenic isotope dating and physical/chemical properties in soils.

I am educated in Physical geography and Quaternary geology at Stockholm university, Sweden with speciality in geomorphology, paleoclimatology and lacustrine sedimentology. My doctoral thesis was entitled; Alpine lake sediment archives and catchment geomorphology; causal relationships and implications for paleoenvironmental reconstructions.

Glacier-landscape interactions and related periglacial processes comprise my main research interests. In order to describe, understand and quantify these processes I apply sedimentological, geophysical and morphological approaches. My current work is part of the SEDITRANS project, where I focus on the formation of saw-tooth moraine ridges and the glacial erosion since Little Ice Age maximum position.

(In Norwegian) Etter at jeg sluttet som en av NGUs direktører i 1999 har jeg fått anledning til å ta opp igjen mine tidligere interesseområder ved NGU. Dette omfatter studier av glasiasjonshistorien innen Midt-Norge. Flere publikasjoner og kart som omhandler dette temaet er ferdigstilt. Videre arbeider jeg for at geologi skal inn i våre nasjonalparker. Det siste har jeg fått anledning til gjennom mitt verv som styreleder i Stiftelsen Folldal Gruver og stiftelsen iNasjonalparker. Sammen med aktører fra fylker og kommuner er det her utviklet og utgitt blant annet geologiske turkart. Moderne database- og animasjonsteknikker er tatt i bruk for at NGU fremover skal kunne vise betydningen av geologi for naturforståelsen.

My research has been concentrated on Quaternary geology (paleoenvironment/paleoclimate, glacial geology, sedimentology, stratigraphy). Currently, I am running projects supported by the Geological Survey of Norway (NGU), the Norwegian Research Council (NFR) and Norsk Hydro AS:

• Quaternary stratigraphy at Jæren, SW Norway: Paleoenvironments, climatic change and faulting. (Funding to E. Larsen: NGU).
• Past Climates of the Norwegian Region (NORPAST 2). (Funding to E. Larsen: NFR, 2003-2006: 1 mill. NOK).
• SEDITRANS - Past and current valley-to-fjord sediment transport - processes and products: A transect from Jostedalsbreen to Nordfjorden, western Norway. (Funding to E. Larsen: NFR, 2004-2007: 9.5 mill. NOK).
• GlaciPet: Ice ages: subsidence, uplift and tilting of traps – the influence on petroleum systems. (Funding to E. Larsen: NFR and Norsk Hydro AS, 2005-2009: 18.8 mill. NOK).

My research interests are within sedimentology of fluvial, lacustrine and coastal depositional systems (particularly tidal systems) and evidence of climate and sea level change in sedimentary archives. I am currently working on the following topics: 

• The extent and distribution of ice-dammed lakes in NW Russia and fluctuation of lake levels (GlaciPet).
• The fluvial archive of the Severnaya Dvina, Mezen and Pyoza rivers in NW Russia.
• Facies architecture in multi-storey glacio-lacustrine basins in NW Russia
• Large-scale fluvial depositional systems from the Nuussuaq Basin, Central West Greenland.
• Tidal rhythmites and their potential as a proxy for palaeo-hydrology. Initial studies have been done in NW Russia and with Raymond Eilertsen, NGU in northern Norway.
