“Seeing” What Killer Whales VisualizeLatest update August 4, 2019 Started on November 4, 2018
Decline of prey, specifically Chinook salmon, has been identified as a threat to the recovery of the Southern Resident Killer Whale population in Canada and the US. However, little is known about whether there are enough fish for them to prey upon. Our mission is to determine how many Chinook are present and how the fish are distributed in areas where increasing and decreasing populations of fish-eating killer whales travel and feed. We are pursuing this goal using sound to visualize life beneath the surface water. Our study will contribute to the recovery of Southern Resident Killer Whales by assessing the availability of prey in habitats used by killer whales.
