Modelling beluga habitat use and baseline exposure to shipping traffic to design effective protection against prospective industrialization in the Canadian Arctic
Abstract Global warming is predicted to reduce sea ice and thereby grant access to new shipping routes in the Arctic, leading to the expansion of human exploitation of natural resources in this region. The accompanying rise in boat numbers could impact the local populations of marine mammals by incr...
