Congrats to Aquatic and Fishery Sciences’ Chelsea Wood, ESA Early Career Fellow

Jodi Young

Chelsea Wood, an assistant professor at the School of Aquatic and Fishery Sciences, has been named an Early Career Fellow of the Ecological Society of America (ESA). The ESA chooses members for this distinction who have made or show potential to make outstanding contributions to a wide range of fields served by the society. Such contributions can include those who advance or apply ecological knowledge in academics, government, nonprofit organizations and the private sector through outstanding contributions to research, education and/or outreach.

Vitamin B-12, and a knockoff version, create complex market for marine vitamins

An oceanographic sampler, known as a rosette, during a 2013 cruise in the North Pacific. Each bottle contains water from different depths, which is how researchers collected samples of the vitamins at sea.

All animals, from humans to whales to sea cucumbers, need vitamin B-12. But only certain microbes can make the complex, cobalt-containing molecule. For land dwellers a main source is the microbes that thrive in animals’ guts, which is why beef is such a good source of B-12. Shellfish also accumulate a lot of B-12. In the oceans, the source of their vitamins for some marine organisms is sometimes mysterious.

Ocean acidification to hit West Coast Dungeness crab fishery, new assessment shows

Dungeness crab.

The ocean acidification expected as seawater absorbs increasing amounts of carbon dioxide from the atmosphere will reverberate through the West Coast’s marine food web, but not necessarily in the ways you might expect, new research shows. Dungeness crabs, for example, will likely suffer as their food sources decline. Dungeness crab fisheries, valued at about $220 million annually, may face a strong downturn over the next 50 years, according to research published today in the journal Global Change Biology.

A University of Washington oceanographer is chief scientist on a voyage in the waters around Antarctica as part of a major effort to monitor the Southern Ocean. Stephen Riser, a UW professor of oceanography, embarked Dec. 24 as part of the Southern Ocean Carbon and Climate Observations and Modeling, or SOCCOM, project to collect better data about the planet’s most remote ocean.

Arctic sea ice loss impacts beluga whale migration

A beluga whale surfaces for air.

The annual migration of some beluga whales in Alaska is altered by sea ice changes in the Arctic, while other belugas do not appear to be affected. A new study led by the University of Washington finds that as Arctic sea ice takes longer to freeze up each fall due to climate change, one population of belugas mirrors that timing and delays its migration south by up to one month.
