My doctoral thesis, which is mainly based on glacial geological/ morphological/ sedimentological methods, deals with the deglaciation of the west coast of Iceland. My post-doctoral research has been focused on the Late Quaternary glacial- and climatic histories of the polar regions and Iceland, with fieldwork in Iceland, Greenland, Svalbard, western Siberia and Antarctica. I have contributed to a number of research fields within glacial and Quaternary geology: Glacial stratigraphy, glacial morphology, relative sea level changes, Late Quaternary glacial and climatic changes, geochronology, glaciotectonics, sedimentary processes, glacial research history. I have also initiated and organised biostratigraphical lake sediment studies on northern Iceland and participated in biostratigraphical studies on Greenland lake sediments and Antarctic moss banks. The research projects outlined below all have the aim of contributing to our understanding of how Late Quaternary environments have developed regionally. One important aspect of working both in the Arctic and Antarctica has been to compare the environmental histories of the polar regions, for a better understanding of the global development of climate and glaciation. A short outline of the research projects I have been involved in for the past years, and which highlight my research profile, is given below:

The deglaciation history of Iceland
The results of my Ph.d. thesis from coastal western Iceland showed that Iceland was subject to extensive Younger Dryas/Preboreal glaciation, and that the history of sea-level changes needed revision. Additional fieldwork on southern Iceland showed that there the Preboreal glaciation was more extensive than previously recognised, and that the deglaciation occurred primarily during the Preboreal. This project has resulted in a number of publications and international lectures. The most important contributions are (a) a new synthesis for the deglacion of Iceland and (b) new data on the dynamics of the postglacial isostatic rebound, with the only two stratigraphically controlled relative sea level curves that exist for Iceland.

Late Weichselian-early Holocene environmental changes on Iceland
Our knowledge and understanding of the vegetation- and climate history of Iceland during and immediately after the deglaciation has been hampered by lack of high-resolution data. During two winter expeditions to the Skagi peninsula on northern Iceland six lakes were cored for sediment records. From one of the lakes, a 12 m long lake sediment core was recovered. It extends back to beyond 11,000 BP, or about 3000 years further back in time than any previous lake sediment core in Iceland. This project achieved a number of important goals: (a) new information on the pioneer vegetation on northern Iceland, developing since Allerřd times; (b) a biostratigraphical record of the Younger Dryas cooling and developments during the Preboreal; (c) extending the N Icelandic tephrostratigraphy 2,500-3,000 years back in time, from ca. 8,000 BP to ca. 11,000 BP. The project has resulted in a number of international publications.

Late Quaternary glacial and environmental history of Svalbard and the Barents Sea
The objective of this project has been to study glacial geological evidence for Late Quaternary glacial and environmental changes on Svalbard and the Barents Sea, with field work on Kongsřya in the central northern Barents Sea, on Prins Karls Forland, west of Spitsbergen, and on Sjuřyena, the northernmost part of Svalbard. Research on the glacial and climate histories of Svalbard/Barents Sea has large relevance for our view of the North Atlantic environmental development. The pace of environmental changes is largely controlled by fluctuations in the the North Atlantic Current, which brings energy and moisture to higher latitudes. The position of the marine polar front and formation of deepwater in the N Atlantic and the arctic basin reflect on the strengt of the North Atlantic Current, and this system paces climate and glacial fluctuations on Iceland as well as in the Barents Sea area. The results from this project up to date indicate that (a) Kongsřya was subject to repeated Late Quaternary glaciations, and that it was close to the dynamic centre of Svalbard-Barents Sea Ice Sheet; (b) Prins Karls Forland was not overridden from east by an active Barents Sea Ice Sheet at any time during the last interglacial-glacial cycle, but experienced local glaciation; (c) Sjuřyena, on the other hand, were overridden by an ice advancing from Svalbard to the south. This project is ongoing, and results are being prepared for international publication: A major effort to core Holocene lake sediments was undertaken 2001-2004, and the results are being worked up for publication. Future glacial geological fieldwork is planned for Nordaustlandet, Svalbard, as well as on the west coast of Spitsbergen. Collaborators: professor Steven L.

Quaternary environmental history of Antarctica
By reconstructing the Antarctic glacial history it is possible to draw climatological conclusions. By comparing the results with corresponding climatological evidence from the Arctic conclusions can be drawn on global glacial- and climatic development. This research program has focused on studying the deglaciation of the presently ice-free Antarctic lowland areas, the relative sea level history and the environmental development after the deglaciation, with the aim of reconstructing the pattern of glacial and climatic changes in the Antarctic Peninsula region and comparing it to corresponding development in the Arctic. I am a senior author on three international publications and co-author on additional seven. I also participated in an American expedition to southern Victoria Land in 1994, and have co-authored one publication originating in that effort. The most important results of this project are (a) a new circumantarctic synthesis on environmental developments since the Last Glacial Maximum, and (b) a new perspective on the Antarctic contribution to global sea-level rise in Holocene. Our data indicates that deglaciation in Antarctica was considerably delayed compared to Northern Hemisphere deglaciation; that Antarctic meltwater input to the worlds Oceans can be seen the mid-Holocene transgressions (such as the Tapes and Littorina transgressions); and that the Holocene climate optimum in Antarctica occurred as late as ca 4000-3000 14C years ago.

bullet Glacial history of the Kara Sea area, arctic Russia
International efforts to investigate the Late Quaternary glacial- and climatic history of arctic Russia, have for the recent few years been coordinated within the so-called QUEEN-initiative (Quaternary Environments of the Eurasian North) of the European Science Foundation. I have collaborated with American, Swedish and Russian colleques on research in the eastern Kara Sea area, with fieldwork on the Yamal- and Yugorski peninsulas, and on Severnaya Zemlya in the Russian high Arctic. The glacial history of the Kara Sea Ice Sheet and its association with the Barents Sea Ice Sheet has beenone of the major unresolved problems regarding the glacial history of the Eurasian arctic. Five field seasons have been carried out within the project: on Yamal Peninsula in 1997, on Yugorski Peninsula in 1998 and 1999, and on Severnaya Zemlya in 2002 and 2003. Our results show that the Yamal Peninsula was subject to a regional glaciation sometime before 40,000 BP, but since then the area has been ice-free. Thus, the Eurasian ice sheet was largely confined to Barents Sea. We also have data which show that the Holocene climate optimum around 70oN in western Siberia occurred between 9000 and 8000 BP. Results on the Late Quaternary development at Yugorski Peninsula show likewise no Late Weichselian glaciation there, but a regional glaciation earlier during the Weichselian. Stratigraphies from both Yamal and Yugorski peninsulas suggest ice movements during the last glaciation from South, i.e. in direction from mainland western Siberia/Polar Urals towards the Kara Sea Basin. Our investigations on Severnaya Zemlya have revealed a complex record of glaciations and marine events during the Late Quaternary.  Collaborators: Steven L.

 Brúarjökull - a surging glacier
Fast flowing ice or palaeo-ice streams have recently been identified as one of the most important controls on the configuration and stability of former ice sheets. The problem, however, is the lack of contemporary analogues for land based ice streams that is necessary to understand their glacio-dynamic behaviour. Despite this, a certain type of glaciers (surging glaciers) that momentarily reaches fast ice flow actually provides an imprint of sediments, landforms and landform assemblages that resembles the situation related to ice streams. The overall aim of the Brúarjökull project is directed towards the study of depositional environments at a contemporary surging glacier. This includes the development of glacial landscapes and associated sediments. Thus, it embraces the interaction between climate-processes-sediments and landforms over time and space involving glaciological, geomorphological, sedimentological and glacial geological disciplines. The results will serve as reference work and inspiration for geomorphological and geological investigations in areas suspected to be influenced by palaeo-ice streams. Reconnaissance work was carried out during the 2003 field season, continued field work was in the Brúarjökull glacier forefield area in 2004, and is planned for the 2005 summer.
