Data from: Use of glacial fronts by narwhals (Monodon monoceros) in West Greenland
Glacial fronts are important summer habitat for narwhals (Monodon monoceros), however, no studies have quantified which glacial properties attract whales. We investigated the importance of glacial habitats using telemetry data from n=15 whales in September 1993-1994 and 2006-2007 in Melville Bay, We...
