Blue whales are also summer residents in the Barents Sea. They probably number 600-1,500 individuals in the North Atlantic. In recent years, this species has been sighted frequently in Svalbard waters, up the west coast at the shelf edge as well as north of Spitsbergen. Similar to the fin whale, it also enters deeply into Svalbard fjords. It is sighted from early summer until late fall, and appears to be extending is seasonal presence in the northern Barents Sea
