A team of scientists studying last year’s eruption of Axial Seamount now says that the undersea volcano some 250 miles off the Oregon coast gave off clear signals hours before the eruption. The findings, plus those from scientists who mapped the lava flow, are published this week in three separate articles in the journal Nature Geoscience. To read more about this research, click here.

In an op-ed piece, Elizabeth Tobin, graduate student in oceanography, writes, “scientists and the media must avoid hyperbolic language when describing crucial environmental issues.” Read more here. Senators Maria Cantwell (WA) and Mark Begich (AK) spoke last week at the Seattle Aquarium about the importance of being prepared to deal with tsunami debris that may land on the west coast. Oceanography Professor Parker MacCready attended the event, and his lab’s oceanographic models are helping inform what may become of some of the debris. Read more here. The coldest deep ocean water that flows around Antarctica in the Southern Ocean has been mysteriously disappearing at a high rate over the last few decades, scientists have found. Sarah Purkey, graduate student in oceanography and lead author of the study, is quoted. Read more here. By filtering through 25 gallons of seawater from Puget Sound, Vaughn Iverson, a graduate student in Oceanography, has managed to tease out and sequence the DNA of a tiny microbe that has eluded scientists for years. Ginger Armbrust, professor and director of the School of Oceanography, is also featured. Read more here. As a new feature of our news blog, each week we will be sharing the latest publications coming from the College of the Environment. We hope you enjoy perusing the studies. CoEnv authors’ names are linked to their public profile pages! (Check out our first installment here.) This week, 3 new articles published by members of the College of the Environment were added to the Web of Science, a giant database of academic papers:

Univ Washington, Applied Physics Lab Journal: Journal of Physical Oceanography  (V Iverson/U of Washington) A graphical view of tens of millions of bases of DNA extracted from a marine microbial community found in Puget Sound, reveals the entangled genomes of bacteria, archaea and viruses. Scientists extracted 2 million of these to map the genome of one particular marine microorganism that had defied investigation. It has proven difficult to figure out the genome of many of the microorganisms in the ocean because they are much less abundant than other, well-known species. This makes it difficult to isolate them and culture them, creating a chicken and egg problem: how do you study them if you can’t grow them, but to grow them you need to know a bit more about them. Just published in Science magazine, researchers from the School of Oceanography have created a way to isolate genomes of microorganisms that may make up less than 7% of a sample, using metagenomics. Vaughn Iverson, Virginia E. Armbrust and others discuss in this UW News article. Here is the original (registration required). |
