Walrus Movements in Smith Sound: A Canada–Greenland Shared Stock + Supplementary Appendix 1 (See Article Tools)
Fifty of 58 walruses (Odobenus rosmarus rosmarus) instrumented with satellite-linked transmitters in four areas in eastern Smith Sound, Northwest Greenland, during May and June of 2010 – 13 and 2015 provided data for this study. These animals departed from the feeding banks along the Greenland coast...
