Houston, We Have Geology!Occasionally, I post various items that are not exotic or from faraway places. I'll be leaving for Alaska soon to run a wilderness river (the Tatshenshini) and so look for a post from that trip soon. In the meantime, here are a few odds and endsI just loved the above-the-fold headline in this mornings Arizona Daily Sun! Geology plays a prominent role in the upcoming New Horizons mission to Pluto. As you can imagine, Flagstaff has more than a passing [...]
"The journey of a thousand miles begins with one step" - Lao Tzu from the Tao Te ChingAnd that step would be to Boeing Field in South Seattle where we boarded our jet. The date was June 10 with a scheduled departure of 9:30 AM. We landed in Osaka Japan on June 11 at 2:30 PM but the flight was not 29 hours long - we crossed the International Date Line and jumped ahead a day.As this is a Private Jet journey, the security check was a little different from the regular and mundane. Our bus drove [...]
Guest Blogger: Audrey Steiner-Malumphy In 2011, Dr. Wiles and his advisees Lauren Vargo and Jennifer Horton cored dozens of trees from Tree Mountain in Alaska’s Glacier Bay National Park and Preserve. Muir Glacier is located northwest of this mountain, named after the esteemed naturalist and preservationist John Muir. Muir first traveled to the area in
Guest bloggers: Kaitlin Starr and Maddie Happ During the summer of 2014, the Columbia Bay team (Dr.Wiles, Nick Wiesenberg, Kaitlin Starr and Jesse Wiles) cored numerous trees near the town of Girdwood, Alaska. The collection is primarily made up of cores taken from living Mountain Hemlock trees from the surrounding forrest. In addition
From climate.NOAA.gov today: This temperature map of Alaska shows the unusual warmth on May 23, 2015, at 2 p.m. local time in Fairbanks. Based on NOAA’s Real-time Mesoscale Analysis data, it shows air temperatures at 2 meters (6.6 feet) above the ground. Temperatures below 45° are shades of blue, and temperatures above 45° are shades of orange and red. The warmest temperatures are located inland—away from the moderating influence of
Last week I was delighted to welcome fellow academics, friends and collaborators from Potsdam Universty, Ghent University, Durham University and The Geological Survey of Belgium to join me for a symposium on subduction zone palaeoseismology. The day-long meeting was an opportunity to present and discuss the different approaches that we use when studying past earthquakes, tsunamis and subduction zone behaviour. Coinciding with Dr Daniel Melnick's Distinguished International Visit, the Pan [...]

Hunga Tonga-Hunga Ha'apai, one of many submarine calderas NE of New Zealand in an island arc, has begun causing some problems for flights in the area. What started as a minor steam and ash eruption has now turned into a semi-major eruption in the area. Steam and ash clouds are reaching extraordinary heights, and the ongoing eruption is rapidly building a new island.Photo from Volcano-discovery.comResidents have reported that the eruption plume was changing hourly from white steam, to black ash [...]
Really good discussion in yesterday’s evening Tectonophysics poster session! Among several points of interest, I met a young PhD student from Montpellier who is doing both fieldwork and numerical modeling in Alaska, dealing with the tectonic configuration of thrust and strike-slip fault interference. This caught my attention immediately because I have been doing both numerical and (mostly) analogue modeling of this type of interference for some time now . Mostly we’ve been looking at the [...]
I missed this retrospective meme last year (as I also did in 2011), but here it is, back again, per DrugMonkey:
The rules for this blog meme are quite simple.
-Post the link and first sentence from the first blog entry for each month of the past year. I originally did this meme, after seeing similar posted by Janet Stemwedel and John Lynch. Prior editions
Here is the outfall of the Pebble Mine and Mt Polley Mine debacles. A report on the Seabridge Gold’s KSM Mine in BC. The report is authored by Salmon Beyond Borders, a coalition of Alaska Native tribal members, commercial, sport and subsistence fishermen, and other groups, in consultation with Earthworks. The press release is at this link. The
When glaciers erode landscapes, they often leave behind characteristic U-shaped valleys. This week’s Monday Geology Picture shows a U-shaped glacial valley on the Seward Peninsula in Alaska. This valley is located just outside of the gold mining town of Nome. Does anyone else have good pictures of U-shaped
Guest bloggers: Zach Downes & Wilson Nelson For me, the trip started in Juneau, Alaska. We arrived in Juneau late with a couple of things to take care of the next day before getting in a small plane and heading to Gustavus, Alaska where Glacier Bay National Park is based. We needed food, XtraTuf boots,
Last Tuesday, Alaska voters rejected a referendum proposal that would have repealed oil and gas production tax legislation signed into law by Governor Sean Parnell in May 2013, known as the "More Alaska Production" Act.
With the referendum rejected, we thought our readers would appreciate a review of what this might mean for the oil and gas industry in Alaska. A recent article we published in Alaska Business Monthly discussed in detail the trends and specifics of the production tax credits that [...]

One day last week I found myself feeling kind of punky. I woke up a bit dizzy, and found that my blood pressure was higher than it usually is. For that reason, I decided to take a sick day. Unknown to me, though, while I was laying about in my government housing unit worrying about my blood pressure, I missed meeting Mary and Brad.When I returned to work the next day, my blood pressure was back to normal but I was still feeling a bit out of sorts. As soon as I walked in the door, another ranger [...]
Gulf of Alaska 2004 Expedition. NOAA Office of Ocean Exploration
This week I have been researching images from deep-sea video on the home page for the NOAA Photo Library, which has housed ALL of the deep-sea and other imagery from NOAA's deep-sea expeditions since 2003, including those of the Okeanos Explorer!
Many of you know that I have participated in the last two
