Allen, Robert C., and Ian Keay. “Bowhead Whales in the Eastern Arctic, 1611–1911: Population Reconstruction with Historical Whaling.” Environment and History 12, no. 1 (Feb., 2006): 89–113. doi:10.3197/097634006776026791. As early as 1611 bowhead whales resident between the east coast of Greenland and the island of Spitzbergen were the subject of intensive commercial hunting effort by Dutch, German and British whalers. By 1911 there was no significant, permanent population of bowhead whales living in these waters.
