SEASONAL OCCURRENCE OF NORTH ATLANTIC RIGHT WHALE ( EUBALAENA GLACIALIS) VOCALIZATIONS AT TWO SITES ON THE SCOTIAN SHELF
Abstract A year‐long acoustic survey for critically endangered North Atlantic right whales was conducted at two sites on the central and western Scotian Shelf. Autonomous hydrophones recorded sound continuously from July 2004 to August 2005. Right whale contact calls (upcalls) were identified using...
