Dr Duncan Muir Post-doctoral research assistant, Uppsala University PhD title “Investigating Magma Storage Conditions at Uturuncu Volcano, Bolivia” 1) The Twitter Challenge: Describe your PhD in 140 characters Investigating pre-eruptive magma storage conditions (pressures and temperatures) of magmas beneath Uturuncu, an actively deforming volcano in the Andes of Bolivia. 2) Where are you now?
WSDOT released an update on February 7 with some conclusions regarding the blockage that has stopped the Alaska Way Viaduct Tunnel Boring Machine, Bertha's progress since December 6. Now they don't think it was necessarily the well casing after all.
They cite two factors that contributed to the blockage. First, the cutterhead was clogged with material. You can see an cool short video of a worker unclogging the cutterhead. Not terribly dramatic, but still cool. The second factor was [...]
This has been a trying winter here on the east coast for working outside. I got spoiled by the last couple of winters, which were generally mild.
Here's what has worked to keep me warm when the temperatures have hovered around zero (F), starting from the inside and working outside:
1. single-layer longjohns (I have a pair of the two-layer wool pants, but frankly, I can only wear so many
Mount Sinabung, located in northern part of the Indonesian island of Sumatra has been undergoing near constant eruptions since September last year. A pyroclastic flow is a superheated (often with temperatures in excess of 500 degrees Celsius) dust and debris … Continue reading
“Despite some difficulties, the project was able to drill down into the molten magma and control it; it was possible to set steel casing in the bottom of the hole; allowing the hole to blow superheated, high-pressure steam for months at temperatures exceeding 450 C, created a world record for geothermal heat.” Quoted from the
The avalanche on Richardson Highway near ValdezAlaska Department of Public Transportation andPublic FacilitiesReuters photo from here.Last Friday avalanches ranging up to hundreds of feet in length and 30-40 feet in depth blocked the Richardson Highway leading to Valdez, Alaska, a town of 4,000 people. This highway connects Valdez to the rest of the Alaska Highway system (however, supplies can be brought into the town by ship.) An even larger avalanche occurred on Saturday, and a 50 mile [...]
It’s coming back. Will it be as cold as the last one at the beginning of the year? Too soon to say but there are growing signs it will last longer and may come in several waves. Numerical weather ensembles (See last two blog posts) are in remarkable agreement that the cold will return. Model guidance is indicating temperatures as much as 40 degrees below normal by later next week!
Over the past week or so the United States has been experiencing extreme temperature lows. In some cases temperatures dropped down to as low as -35 degrees Celcius. Whereas on the other side of the Atlantic, the United Kingdom has … Continue reading
We may never get a good location for frost quakes, because of simple physics. Nearly all the seismometers are in remote fields far from trees and electrical facilities. The standard arrangement is to use a solar panel, and a satellite dish. That means we can put them in anywhere.
The downside happens during a miserable ice storm and when temperatures plunge down to the minus-minus zone.
I'm back from a cottage in Haliburton. Wow it was -27 oC this morning! I haven't been in these temperatures since the 70's when I used to go winter camping. Of course, then it was -40, but who can tell the difference? Now, since I put no weight on the 'momentum' of our last warming trend, I am convinced we are entering a new 70's-style cold time. It will be fun to track the warmists

Lately I’ve been poking around the Virgin River Canyon Recreation Area, pondering the rocks and trying to figure things out in the Virgin River Gorge. Sedimentary rocks of the Virgin River GorgeOne recent afternoon I was moseying about, trying to eyeball some extensive gypsum layers in the distant cliffs. This gypsum is part of the Woods Ranch Member of the Toroweap Formation and would be located beneath some younger Kaibab Formation sediments at the top of the cliffs. These rocks are [...]
Melting ice caps may not be the only problem the Arctic has to worry about as the climate changes. As temperatures rise, permafrost melts earlier and stays wet longer. When plants and other organic material in the soil thaw, they decompose, releasing huge quantities of methane and carbon
www.mnn.com All it takes is a flash. Lightning strikes the ground, creating temperatures of more than 3,000 degrees. The sand around the lightning strike fuses together, and fulgurite is formed. What are fulgurites? The word – based on the Latin world for thunderbolt – refers to a hollow glass tube formed when lightning strikes soil,
“Within 35 years, even the lowest monthly dips in temperatures will be hotter than we’ve experienced in the past 150
Alan Seltzer, a senior at Columbia University, traveled to New Zealand this past summer to work on field experiments aimed at reconstructing temperatures in the region over the last 20,000 years. His adviser, geochemist Martin Stute, is working closely with colleagues at Lamont-Doherty to understand how the southern hemisphere came out of the last ice
Human activity changes the environment, as last week’s release of a report by the Intergovernmental Panel on Climate Change reminds us. But not all change is bad. One way in which animals and plants respond to warming temperatures, for example, is to move beyond their historical distributions, just as they do when they are transported to new regions by humans. The response of people who
Investigating the early earth faint young sun problem with a general circulation model

Fall is coming! Leaves are changing color, temperatures start creeping down, and gardeners will be able to get back outside without the threat of heatstroke. Well, in theory. This is Houston, after all. But despite the fact that it’ll be … Continue reading
Habitable conditions on Earth will be possible for at least another 1.75 billion years – according to astrobiologists at the University of East Anglia.
Findings published today in the journal Astrobiology reveal the habitable lifetime of planet Earth – based on our distance from the sun and temperatures at which it is possible for the planet to have liquid water.

People started warning me about the mosquitoes back in April. It sounded grim. But when I arrived in Finnish Lapland in August, the mozzies had peaked earlier in the season when temperatures were unusually high, and were all dead. This was a fortunate escape: Miska Luoto of the University of Helsinki and his team of
