3:18 PM | Report: Global Shale Gas Development And Water Availability
This is something that I have written about before in the context of shale gas development from Indian sedimentary basins. The availability of fresh water might set up conflicts with agriculture demands and limit exploitation of shale gas.A report by the World Resources Institute on the global situation points out the same problem elsewhere in many areas of the world.38 percent of shale resources are in areas that are either arid or under high to extremely high levels of water stress19 percent […]

12:32 PM | iMonsoon: Das Leben eines Sedimentologen
Die Hauptaufgabe der JOIDES resolution (oder kurz JR) ist es, unter dem Meeresboden zu bohren und möglichst intakte Bohrkerne der Sedimente zu erhalten. Sedimente bestehen aus Ablagerungen, die sich im Laufe der Jahrmillionen auf dem Meeresboden angesammelt haben und dort - im Gegensatz zu den meisten Ablagerungen an Land - erhalten geblieben sind. read more

12:00 PM | Warming Pacific Could Release Tons of Frozen Methane
The Pacific Ocean, whose waters are heating up due to climate change, may accelerate the problem by releasing millions of tons of methane gas that's stored beneath the ocean floor.

11:00 AM | Outreach on the slopes.
One of the beauties of living in Munich is that the Alps are, practically, on your door step. As I mentioned in one of our more recent posts, now that I am here, I’m looking forward to exploring the city, its surroundings and further afield! Making it to the top That is exactly what I did a few weekends ago. After a little research, I chose to visit the town of Garmisch-Partenkirchen, at the foothills of the Alps. I’d discovered it offered some good hiking and that the town itself […]

9:00 AM | Images of Guatemala (8) – Volcanic Observatories
The volcanic observatories, run by the National Institute for Seismology, Volcanology, Meteorology and Hydrology (INSIVUMEH), are based close to Guatemala’s active volcanoes, including Fuego and Santiaguito. Observers, located at each observatory, make observations and work with those in the local community to share information about the volcano. Our fundraising project will be working to strengthen their capacity and ability to serve these communities. — Each Friday we are […]

8:56 AM | Halftime Report on Stormageddon: The View from the Great Valley (possibly a Great Lake now)
Source: IntellicastThe predicted atmospheric river storm has arrived in California. Not just northern or central California, but pretty much the entire state. These are the kind of storms that can start us on the road towards breaking the drought, but it will take a lot more like this before we can dig ourselves out of the worst drought in centuries here in the Golden State. The water deficit is truly that bad.Atmospheric river storms carry as much water as more than dozen Mississippi Rivers, […]

5:50 AM | What Do Category 5 Hurricanes Have To Do With The Amazon River?
This freshwater plume inhibits the mixing of colder water beneath the surface, and thus can add a lot of heat to an already powerful hurricane. The NASA Aquarius satellite has a sensor that can measure ocean surface salinity, and it’s data produced the the video below. A paper about this plume and how it can affect hurricanes was published in Geophysical research Letters in 2012. It’s free to read here.

5:15 AM | How bigsmall was Aquilops?
If you’ve been reading around about Aquilops, you’ve probably seen it compared in size to a raven, a rabbit, or a cat. Where’d those comparisons come from? You’re about to find out. Back in April I ran some numbers to get a rough idea of the size of Aquilops, both for my own interest and […]

11:58 PM | Geo 730: December 11, Day 710: Mount Hood Ski Bowl
There's something a little forlorn about ski areas in warm weather. It's like looking at a road that's closed to traffic... due to circumstances beyond their control, they are unable to serve their purpose. On the plus side, there was a really nice view of Hood, and a somewhat different perspective of Crater Rock. If you're going over this pass, but don't have time to drive up to Timberline, you should've planned more carefully, this is at the upper end of the small town of Government Camp, but […]

11:53 PM | Super-Fast Jet Makes Jets To Europe Super-Fast
Departures were being delayed from the U.S. to the UK to keep aircraft from arriving to early in Europe. You have to feel for the folks flying from Heathrow to Seattle though; add two hours to an already LONG flight! I experienced this once on a flight from Atlanta to London, and arrived an hour early. We sat on the plane though waiting for a gate to open up!

11:48 PM | The YORP Effect and Bennu
The YORP effect is a phenomenon that affects the rotation rate and pole orientation of an asteroid. YORP is an acronym that combines four scientist’s names: Yarkovsky, O’Keefe, Radzievskii, and Paddack.

9:56 PM | Geo 730: December 10, Day 709: Crater Rock
Here, we've come around to the south and far enough west that we can clearly see Crater Rock, a remnant dome from the most recent eruptive period (See "Old Maid Eruptive Period," near the bottom of this USGS page). It's that pointy dome near the middle of the summit amphitheater. The apron extending down the slope below it consists of pyroclastic flow deposits from repeated collapses of domes that grew during that eruptive phase. Timberline Lodge, our ultimate destination on this hastily […]

7:30 PM | Talking Climate: a New Guide to More Effective Communication
What motivates people to accept or reject climate change? Do financial incentives prompt us to change behavior, or are public recognition and belonging to a social trend more effective? What do personal and political values have to do with attitudes toward climate change? A new guide to climate change communication comes out this week with some of the answers.

5:46 PM | The race for useful offsets
We've been working on a 3D acquisition lately. One of the factors influencing the layout pattern of sources and receivers in a seismic survey is the range of useful offsets over the depth interval of interest. If you've got more than target depth, you'll have more than one range of useful offsets. For shallow targets this range is limited to small offsets, due to direct waves and first breaks. For deeper targets, the range is limited at far offsets by energy losses due to geometric spreading, […]
