Exploring Small Vessel Interactions with Cetaceans in the Salish Sea

Small vessel interactions with cetaceans (whales, dolphins and porpoises) in the Salish Sea is poorly understood. This is of concern as vessel impacts, such as acoustic impacts and behavioural disturbances, have been categorized as a key threat to the recovery of various cetacean species. To minimize vessel impacts on cetacean species, the Canadian Department of Fisheries and Oceans (DFO) and American National Oceanic and Atmospheric Administration (NOAA) have drafted and updated over the years mandatory marine mammal viewing distance regulations around cetaceans.
