Aerial survey of walrus haul-out sites in west Spitsbergen and Moffen
ABSTRACT In July 1992 two aerial surveys were conducted to assess the size of the walrus ( Odobenus rosmarus rosmarus ) population at haul-out sites reported on the northwest coast of Spitsbergen and on Moffen. Walrus have been extensively hunted in Svalbard during the past 350 years, and in 1952 co...
