New observations find Alaskan glacier melt rates significantly higher than predicted by theory

New acoustic observations mapping the changing face of the LeConte Glacier in southeast Alaska show that the rate of submarine melt is much higher than previously predicted by scientific theory.

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.

Crustacean’s life in low-oxygen water suggests there’s more than one way to survive hypoxia

A tidepool crustacean’s ability to survive oxygen deprivation though it lacks a key set of genes raises the possibility that animals might have more ways of dealing with hypoxic environments than had been thought.

Study may solve long-standing mystery of why atmospheric CO2 was lower during ice ages

A combination of sea water temperatures and iron from dust helps explain variations in atmospheric carbon dioxide levels during ice ages.

Scientists discover how climate modulates fertilization of North Pacific Ocean with Asian dust

The vast subtropical “gyres” – large systems of rotating currents in the middle of the oceans – cover 40 percent of the Earth’s surface and have long been considered biological deserts with stratified waters that contain very little nutrients to sustain life.
