DUBLIN—Dr. Scott Baker, a pioneer in the use of DNA to better understand the population structure, abundance, and genetic diversity of dolphins and whales, spoke recently at University College Dublin about new research that could help shape conservation measures for North Pacific humpback whales.

Scott Baker is investigating genetic diversity of dolphins around the South Pacific as part of his Pew Marine Fellowship project, “A Pattern of Dolphins.” Baker, a 2011 fellowship recipient and a professor and associate director at the Marine Mammal Institute at Oregon State University, and his Ph.D. student, Renee Albertson, recently participated in a survey of the islands’ waters.

The saga of Flex the whale continues to deliver surprises a year after the 13-year-old male western (North Pacific) gray whale was tagged and took scientific observers on a four-month, satellite-tracked ride, far from the Asian coast where he was expected to migrate, across the Bering Sea, through the Gulf of Alaska and down the west coast of North America.

“Though humpback whales are found in all oceans of the world, the North Pacific humpback whales should probably be considered a sub-species at an ocean-basin level – based on genetic isolation of these populations on an evolutionary time scale,” said Scott Baker, associate director of the Marine Mammal Institute at Oregon State University’s Hatfield Marine Science Center and lead author on the paper.

Second, if trade in whale meat is legalized, it could be difficult to identify black market meat. Monitoring and enforcement would be a challenge. "These problems are not easily solved," adds Scott Baker of Oregon State University, Corvallis. His molecular sleuthing of whalemeat markets has shows a large trade in illegal or unreported whale products. A return to commercial whaling, he suspects, would provide even greater incentives for illegal hunting.

Markus Horning, pinniped ecologist for the Marine Mammal Institute, will venture to the Antarctic in October to study Weddell seals (Leptonychotes weddellii), the southernmost mammals on the planet.

Scientists are warning that a new form of unregulated whaling has emerged along the coastlines of Japan and South Korea, where the commercial sale of whales killed as fisheries "bycatch" is threatening coastal stocks of minke whales and other protected species.

Global connections across the Pacific Ocean in science, economics and policies — and how these things affect Oregon's ocean — are the focus of the eighth annual Heceta Head Coastal Conference, Oct. 26–27 at the Florence Events Center. Scientists, policy-makers and community leaders — including Oregon first lady Cylvia Hayes and Oregon State University marine mammal specialist Bruce Mate — will address the theme “Oregon's Oceans: Bringing the High Seas Home” during the two-day conference, which is open to the public.

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.
