Northern bottlenose whales are found only in the North Atlantic, from New England, USA to Baffin Island and southern Greenland in the west and from the Strait of Gibraltar to Svalbard in the east (c. 38ºN to 72ºN; Mead 1989; Gowans 2002). There are reports from the Mediterranean Sea (Cañadas and Sagarminaga 2000), and some extra-limital records from the Baltic Sea. The best-known subpopulation of the northern bottlenose whale, the best known of all beaked whales, occurs in the waters over “The Gully,” a large submarine canyon off Nova Scotia, Canada (44ºN, 59ºW; Reeves et al. 1993). However, there have been strandings and at least one sighting as far south as North Carolina in the western Atlantic (Mead 1989). The Gully is the southernmost area of consistent northern bottlenose whale presence in the western Atlantic (Wimmer and Whitehead 2004). In the eastern Atlantic, bottlenose whales are occasionally observed off the Azores (Steiner et al. 1998), and have been seen as far south as the Cape Verde Islands (15ºN; Ruud 1937). The pelagic distribution extends from the ice edges south to approximately 30°N.
