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.
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 was interviewed by the BBC regarding humpback whale migrations for their website "World on the Move". For a link to the website and audio recording, please click on link to story.
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.
For the past several weeks, gray whales that spent the spring breeding or calving in the waters off Mexico have been arriving in the Pacific Northwest to feed for the summer and fall, including areas along the Oregon coast. But gray whales aren’t the only species of whale that can be seen off Oregon, according to experts at Oregon State University’s Marine Mammal Institute.
"Hambleton took the meat, froze it, and the following morning sent it by courier to Scott Baker, the associate director of the Marine Mammal Institute at Oregon State University and an expert in cetacean molecular genetics. Baker, who recently established a database of whale, dolphin, and porpoise DNA, identified the meat as sei, the fourth largest of the baleen whales." [The New Yorker, Nov. 4, 2013]
Bruce Mate, director of the Marine Mammal Institute at Oregon State University, who has been part of the satellite tagging team both years, said he expects the Russian whales to stay around Sakhalin Island until January, which is when Flex took off.
“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.
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.
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.

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.
"It's exciting evidence for a previously unrecognised species within the ancient lineage of Amazon river dolphins," says Scott Baker of Oregon State University in Newport. "Yet it's already rare, and its habitat is now fragmented by dams."
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.
NOAA ship Gordon Gunter departed July 1st to continue its mission to evaluate the effects of the Deepwater Horizon BP oil spill on whales and dolphins in the Gulf of Mexico, including the endangered sperm whale. This project includes leading researchers from Cornell University, Oregon State University, and Scripps Institution of Oceanography, who will work with NOAA scientists to monitor the distributions and movements of whales over the next several months.
