Drones can be powerful tools in gathering important health data about wildlife, including marine species like the Salish Sea’s endangered killer whales. Scientists have already established the benefits of collecting breath samples to monitor orca health, but we wanted to scientifically understand if it is less invasive than previous sampling methods–namely the use of a long pole with a petri dish extended from a nearby boat toward the whale’s blowhole.
A new study published in the peer-reviewed journal, Marine Mammal Science, led by SeaDoc Society Research Assistant Catherine Lo, answered that question by analyzing more than 1,000 drone-collected killer whale breath samples.
