Résumé :	During the years 1992-1998 the National Environmental Research Institute, department of Arctic Environment (previously Greenland Environmental Research Institute), carried out several ship-based and aircraft-based seabird surveys. These surveys were aimed at seabird colonies, moulting eiders and concentrations of spring and autumn migrants along the coasts and in shelf waters. All the surveys were related to the identification of areas sensitive to oil spills and the collecting of baseline data, as offshore oil exploration activities are increasing in West Greenland waters. During these surveys many unusual observations were made. Several Leach's Storm Petrels Oceanodroma leucorhoa were seen in offshore waters off southwestern Greenland, indicating that this species is more frequent than previously reported, at least in October. Very few Great Shearwaters Puffinis gravis were seen, and the occurrence of this species in West Greenland waters may have decreased in recent decades. A p air of Whistling Swans Cygnus c. columbianus has been breeding on Svartenhuk peninsula since 1988. There are only two other records of straggling individuals of this swan in Greenland. The breeding range, and probably also the population size of Snow Goose Anser caerulescens is still increasing. A Ring-billed Gull Larus delawarensis was seen at Thule Air Base, being the second record from Greenland. Records of breeding and probably breeding Lesser Black-backed Gulls Larus fuscus and Herring Gulls Larus argentatus were obtained at sites along the coast as far north as Sisimiut. Straggling Kumlien's Gulls Larus glaucoides kumlieni and Thayer's Gulls Larus thayeri were recorded at several localities in West Greenland and offshore in shelf waters. Both taxa have probably been overlooked previously. Great Black-backed Gull Larus marinus has expanded its breeding range towards the north since about 1985 and is now a common breeder along the outer coast of Upernavik district as far north as 74degreeN. A large influx of Puffins Fratercula arctica, probably of Icelandic origin, was recorded on the shelf south of 66degreeN in October 1993.
