Sea levels to continue rising after current Paris agreement emission pledges expire in 2030

Sea levels will continue to rise around the world long after current carbon emissions pledges made through the Paris climate agreement are met and global temperatures stabilize, a new study indicates.

‘State of the Coast’ conference set for Nov. 9 in Gleneden Beach

Registration has opened for Oregon Sea Grant’s annual State of the Coast conference, which will be held Nov. 9 at the Salishan resort in Gleneden Beach and will provide opportunities to hear about marine science and policy issues facing the Oregon coast.

Corvallis Science Pub features mega-rafting of invasive species

The 2011 Great East Japan earthquake and tsunami launched a flood of debris across the Pacific Ocean. At the Corvallis Science Pub on October 14, Jessica Miller, professor in fisheries and wildlife at Oregon State University, will discuss what she and other scientists learned about the nearly 300 invasive species that hitchhiked their way on the debris to Hawaii and the Northwest.

Ocean acidification and hypoxia plan outlines Oregon’s commitment to addressing climate impacts

Oregon has a new roadmap for addressing rising ocean acidification and hypoxia – two climate change-induced conditions that could have widespread consequences for the state’s ocean ecosystem and the economy.

How long does a whale feed? New data gives insight into blue and fin whale behavior

Researchers using electronic tags were able to monitor blue and fin whales off the coast of Southern California over multiple weeks, providing new insight into the feeding behaviors of the two largest whale species. The researchers also found evidence of differences in the feeding intensity and habitat use of males and females of both species.

Underwater soundscapes reveal differences in marine environments

Storms, boat traffic, animal noises and more contribute to the underwater sound environment in the ocean, even in areas considered protected, a new study from Oregon State University shows.

Strong storms also play big role in Antarctic ice shelf collapse

Warming temperatures and changes in ocean circulation and salinity are driving the breakup of ice sheets in Antarctica, but a new study suggests that intense storms may help push the system over the edge.

 

Modeling predicts blue whales’ foraging behavior, aiding population management efforts

Scientists can predict where and when blue whales are most likely to be foraging for food in the California Current Ecosystem, providing new insight that could aid in the management of the endangered population in light of climate change and blue whale mortality due to ship strikes, a new study shows.

The Sounds of Science: Acoustic tags reveal Dungeness crab range – and some interesting visitors

Oregon State University marine ecologist Sarah Henkel glued acoustic tags onto several legal-sized Dungeness crabs near the mouth of the Columbia River and off Cape Falcon, then deployed acoustic receivers north and south of the two locations to learn more about their movements.

OSU names NOAA director of marine mammal science as head of its Marine Mammal Institute

Lisa Ballance, an ecologist with the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center in La Jolla, California, has been named director of the Marine Mammal Institute at Oregon State University.
