FOLLOWUP: New study published by scientists studying Alki Point methane bubbles

A little over one year ago, we reported on that University of Washington research vessel’s work off Alki Point, studying methane bubbles seeping from the Seattle Fault. UW oceanography professor Paul Johnson explained the project involving the R/V Rachel Carson, years of work that could someday help predict earthquakes, among other things. He also shared this undersea video showing the bubbles:

This week, the UW announced that research for which Professor Carson was lead author has been published in the January issue of Geochemistry, Geophysics, Geosystems. The UW post also talks about some of what’s happened since our report, and what’s next:

… In follow-up work, scientists used underwater microphones this fall to eavesdrop on the bubbles. Shima Abadi, an associate professor at the University of Washington Bothell, is analyzing the sound that bubbles make when they are emitted. The team also hopes to go back to Alki Point with a remotely operated vehicle that could place instruments inside a vent hole to fully analyze the emerging fluid and gas. …

The area off Alki Point is not the only methane-bubble site they’re studying – others in the region include an area off Kingston. Among the mysteries they have yet to solve is the source of the methane.

    Well. That’s a little freaky.

    I’m going to do some research on this!

    That’s fascinating! I’m eager to hear what they find about the source of the bubbles. Anything that can build up information to help us predict earthquakes is good news in my book!

    Noticed the same type of bubbles near the west shore of the Duwamish just north of Kellogg island. Not sure if it was methane of course, just a similar pattern.

    I’ve been on that ship…it’s pretty impressive.

    The headline implies that the study has been published.  If so, what were the results?  I’m only seeing the subject matter, as well as ongoing studies.

Sorry, comment time is over.
