After a decade of service on the SeaDoc Society’s Board of Directors, Rochelle Severson and Kevin Campion will cycle off, with Board Member Ardi Kveven taking over as Board Chair.
The story of how SeaDoc Society went from a big idea to a proper organization with a scientist and a mission and a proper name, as told by a vital board member who was in those early conversations.
North American river otters (Lontra canadensis) are semi-aquatic mammals that range over most major river drainages, large lakes, and coastal marshes of North America. On the west coast, from Northern California (Bouley et al., 2015) to Alaska (Bowyer et al., 2003), river otters forage in and rely on healthy subtidal and intertidal zones where they feed on a variety of marine fish and invertebrates. The subspecies L. c. pacifica is found throughout the Salish Sea’s rivers, estuaries, coastlines, and coastal islands and plays an important role in the nearshore marine ecosystem. They are often confused with sea otters (Enhydra lutra) by the public because they are otters swimming in the sea. River otters do use and rely on marine resources, but taxonomically, they are not considered marine mammals like sea otters.
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.
