Marine Mammal Institute

The OSU Marine Mammal Institute is a multi-disciplinary facility incorporating the work of academics from engineering, genetics, agriculture, aquatics, ecology, veterinary medicine, biology, and communications. As the only institute of its kind, the Marine Mammal Institute combines the efforts of top researchers from around the world to continue the legacy of discovery and preservation of critical habitats of target species and to understand how those species interact with their environment and human activities.

Chasing Giants: A whale tracker reflects on four decades of searching for answers

Every spring for almost thirty years, Bruce Mate makes his way down to Baja to reconnect with the same female gray whales. Over four decades, he’s witnessed their transition from smooth-skinned youth into mothers. More recently, he’s seen wrinkles start to appear around some of their eyes, each eye roughly the size of a baseball. He’s met and played with their offspring, even seeing some from the next generation become mothers themselves. These whales feel like family to him.

Whale Bone Memorials, by Nature and Humans

To Scott Baker of the Marine Mammal Institute at Oregon State University, and a National Geographic grantee, the whales’ large size and low but prominent dorsal fins identified them as most likely Sei whales. Little is known or understood about these large filter feeders, so learning of their activity in these waters, Baker is eager to begin a project to track and observe them here.

Autopsies from space: who killed the sea lions?

A decade ago, we set out to unravel deep ocean crime scenes we weren’t even sure existed. The crime? Endangered Steller sea lions were rapidly disappearing in parts of Alaska. Their numbers dropped by 80% in three decades, yet only rarely did anyone see or sample dead sea lions. Live sea lions studied in the summer when they haul out to breed seemed healthy and had healthy pups.

We wanted to know when, where, and why sea lions die. To unravel the mystery, we needed information from those animals that we don’t see, those that might not breed, those that might never come back ashore. So we developed a special monitoring tag that could send us data about the sea lions we can’t directly observe.
