Enhancement of evaporation from a large northern lake by the entrainment of warm, dry airThe turbulent exchange of water vapor and heat were measured above Great Slave Lake, Northwest Territories, Canada, using the eddy covariance method for most of the ice-free period in 1997, 1998, and 1999....
Short note terrestrial predation by polar bears: not just a wild goose chase... Although polar bears (Ursus maritimus) are spe-cialist predators of seal pups on the Arctic ice pack, the use of terrestrial food sources during the ice-free period has received increased attention in recent years in light of climate predictions....
Arctic double counts in aerial surveys to estimate polar bear numbers during the ice-free period... The doublecount technique could be used to estimate the size of bear populations retreating on the islands and the coasts of Hudson Bay during the ice-free period, but its costs would have to be evaluated and compared with current techniques before including this method in management programs
Terrestrial foraging by polar bears during the ice-free period in western hudson bay... Food habits of polar bears on land during the ice-free period in western Hudson Bay were examined between 1986 and 1992....
