Summary

Northern bottlenose whales (Hyperoodon ampullatus) have been studies since 1988 in the Gully, a deep submarine canyon near Sable Island, Nova Scotia. A population of about 300 individuals, including all ages and both sexes, uses the area year round. This is the most southern population of this North Atlantic species, and is probably distinct from the animals found in more arctic waters. The study of the bottlenose whales in the Gully is of special significance since it is the only systematic research which has ever been performed on any population or species of beaked whale. The very small, 8 x 12 km, core range of the bottlenose whales in the Gully is close to a major transatlantic shipping route and is surrounded by oil and gas discoveries. Increased marine traffic, oil or toxic chemical contamination as well as floating debris and noise pollution are potential hazards for the whales and their prey species. Given its low numbers, residency habits and relative isolation, the population of bottlenose whales in the Gully may be especially vulnerable to these threats. There is an urgent need to protect its habitat.
