Sarychev Peak eruption update for 6/17/2009

The eruption at Sarychev Peak is continuing to disrupt all sorts of flights that head towards Asia. There are lots of unhappy travelers who have had to "enjoy" a 12 hour flight that took them from Newark, NJ to ... Newark, NJ (see yesterday's Continental Flight 009 above). There have been a multitude of flights affected by the ash, many reported here on Eruptions by travelers or relatives (keep them coming!) It will be interesting to see how long the airlines will have to deal with changing flightpaths and diverting aircraft due to this ongoing eruption.

In another front for the eruption, it appears that Sarychev Peak is releasing a fairly significant amount of sulfur dioxide that is drifting across the Pacific Ocean. The NASA Earth Observatory has an image of the sulfur dioxide plume. Not only does this now register as the largest sulfur dioxide event of the year, but the extent of the plume suggest that the ash column might be as tall as 21 km / 69,000 feet! The SO2 from the eruption can be traced as far as the Alaskan Aleutians, while the visible plume heads thousands of kilometers into the Pacific.

A very interesting new paper was published today in PLoS Biology:
I'm stuck in the US East Coast ice and snow trying to get home after some science work for our nation's health agency (that is my rationale for posting this on my Sb blog). My four-hour equipment and weather delay has now turned into a canceled flight.
I thought many of you would want to know about this book. It is from the National Academies Press. Costs 40 bucks if you want the dead tree version, but the PDF is free. Gotta love the National Academies. Here's the description provided by the NAP:

Any estimates of the quantity of sulfur dioxide released so far from this event?

I'm still learning from you, while I'm trying to achieve my goals. I certainly love reading all that is written on your blog.Keep the stories coming. I liked it!
