Other petroleum geological work Although the main focus in 2001 was on the West Greenland 2002 licensing round, field work was also carried out in East Greenland. A project on the postbasaltic, Palaeogene and Neogene sediments in central East Greenland was initiated (Larsen et al. 2002, this volume; Nøhr-Hansen & Piasecki 2002, this volume). These sediments have received renewed interest as a result of the recent exploration activities around the Faeroe Islands. Lithostratigraphy, biostratigraphy and sequence stratigraphy studies will provide further insights into basin evolution and uplift history of the northern North Atlantic during Palaeogene time. After almost 10 years of intensive field work in the Disko–Nuussuaq region in West Greenland, many results important for the evaluation of the exploration potential of the offshore areas are emerging. Although field work was completed in 1999 (Christiansen et al. 2000), several studies have been published in 2001, including those on organic geochemistry of coals (Bojesen-Koefoed et al. 2001b), sequence stratigraphy (Dam et al. 2001), taxonomy (Nøhr-Hansen & Heilmann-Clausen 2001; Nøhr-Hansen et al. in press) and discussions of the tectonic history (Chalmers & Pulvertaft 2001). The last of the planned 1:100 000 geological maps of the region was also printed in 2001 (Pedersen et al. 2001). Many other studies of basin history, sedimentological and structural models, lithostratigraphy, organic geochemistry of seeps, etc. are in progress. Acknowledgements Funding of the biostratigraphic project Regional correlation of Mesozoic–Paleogene sequences across the Greenland–Canada boundary was provided by the Danish Energy Research Programme (ENS J.nr. 1313/01-0022), the Bureau of Minerals and Petroleum (BMP), Government of Greenland, and Phillips Petroleum on behalf of the Sisimiut-West licence group. Funding of the source rock project Cretaceous source rocks, comparison between West Greenland and relevant Canadian and US basins was provided by BMP. The Geological Survey of Canada, the U. S. Geological Survey, the Canada–Newfoundland Offshore Petroleum Board, St. John’s and the Nova Scotia Offshore Petroleum Board have all been very helpful in the selection and handling of sample material for these two projects. Funding of the Geohazard project was also provided by BMP.
