An Oregon State researcher is raising some new scientific doubts about the National Marine Fisheries Service Sea Lion biological opinion. Markus Horning has been tagging Sea Lions in Prince William Sound and finding that predators like Killer Whales and Sharks are killing a larger proportion of their pups than expected.
Researchers at Oregon State University and the Alaska Sealife Center started tracking 36 juvenile Steller sea lions in 2005. By November, 12 had died, a death rate that's not exceptional, OSU marine mammal expert Markus Horning said Thursday.
A new study suggests that the impact of predation on juvenile Steller sea lions in the Gulf of Alaska has been significantly underestimated, creating a “productivity pit” from which their population will have difficulty recovering without a reduction of predators.
Each fall, Scott Baker teaches a 3 credit course on 'The natural history of whales and whaling' (FW499/599) based at HMSC. The students finished the fall quarter with a debate, following a Karl Popper format.
The Symposium and Workshop on ‘Living whales in the Southern Ocean: Advances in methods for non-lethal cetacean research’ is scheduled for 27-29 March 2012, in Puerto Varas, Chile. The symposium and workshop are an initiative of the Southern Ocean Research Partnership (SORP), a multi-national programme to advance the conservation agenda in the International Whaling Commission (IWC) and to improve our scientific understanding of the population dynamics and ecological roles of whales in the Southern Ocean.

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.
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.
After being hunted to local extinction more than a century ago and unable to remember their ancestral calving grounds, the southern right whales of mainland New Zealand are coming home. A new study published today has shown for the first time that whales from a small surviving population around remote, sub-Antarctic islands have found their way back ...
6-22-11. An unprecedented decade-long study of apex predators in the Pacific Ocean found a wider range of distribution among some species than previously thought, unknown relationships between other species, and the importance of biological “hotspots” to the survival of most of these sea creatures.
