Doug Sandilands is a leader in the field of whale entanglement response and began his career working with the Vancouver Aquarium Marine Science Center in 2000. During his time with the aquarium and as a founding member of Cetus Research & Conservation Society, a Canadian nonprofit, he worked to build capacity in British Columbia to respond to entangled whales. For ten years Doug worked in the Cetacean Research Lab with the B.C. Cetacean Sightings Network growing the network to nearly 2,000 contributors submitting over 40,000 sightings. In 2011 Doug became the operations manager for the Marine Entanglement Response team at the Center for Coastal Studies in Provincetown, MA. Over the next five years he responded with the MAER team to forty large whale entanglements and thirty-five leatherback sea turtle entanglements. Doug also assisted with humpback and fin whale studies (collecting photo ID, biopsy, breath samples and assisting with tagging projects). As an authorized responder with the Large Whale Entanglement Response Network Doug helped to train nearly sixty other large whale entanglement responders.
