Data from: Behavioural analysis of multi-year satellite telemetry data provides insight into narwhal (Monodon monoceros) winter prey selection in Baffin Bay

Data here are from 25 narwhals captured and tagged at Kakiak Point (72º 41’ 00” N, 86º 41’ 20” W) in Admiralty Inlet near the community of Arctic Bay, Nunavut, in August 2009, and in Tremblay Sound (72º 21’ 23” N, 81º 6’ 24” W) near the community of Pond Inlet, Nunavut, in August 2010, 2011, and 2012. Argos locations were re-analysed using a Kalman filtering (KF) algorithm and dive histos files are the original data provided by Wildlife Computers. We would like to acknowledge the communities of Pond Inlet and Arctic Bay (and Hunters and Trapper Organizations), for their support in narwhal research program, including capture and instrumentation of narwhals over the years.
