    Imaging beneath the southernmost volcanoes in the East Africa Rift

    The last time we visited the southern part of the East Africa Rift, we were responding to an unusual series of earthquakes in December 2009 that shook northern Malawi. This time, we return to this part of the rift system as a part of a more comprehensive effort to understand the underpinnings of this continental…

  • Only 144 Miles, Yet Worlds Apart

    Only 144 Miles, Yet Worlds Apart

    144 miles separates Kangerlussuaq from Raven Camp. Not far really, just 144 miles – like traveling from the southern tip of New York City up to Albany. Flying at 270 knots we can be there in about half an hour, no time at all, and yet to the casual observer they seem worlds apart.

    Gone Fishing…Took IcePod!

    When we sat down to map out the flight plan, our request to the crew for locating lakes met with an easy nod: No problem at all. It took only seconds to register that our definition of lakes might differ from theirs.

    ‘Lipreading’ the Icesheet

    Even the most skilled of English language lipreaders are only able to tease apart about 30 percent of the information being shared, I read in a recent article. The author, herself deaf, noted that in some transmissions, the information capture is higher, while in others, nothing is collected. An average of 30 percent information transfer…most…

    In Ethiopian Desert, a Window into Rifting of Africa

    A new study in the journal Nature provides fresh insight into deep-earth processes driving apart huge sections of the earth’s crust. This rifting mostly takes place on seabeds, but can be seen in a few places on land—nowhere more visibly than in the Afar region of northern Ethiopia.

    Tides Play a Role in Triggering Undersea Earthquakes

    Can shifting tides trigger earthquakes? Research done by Maya Tolstoy, a geophysicist at Lamont-Doherty Earth Observatory, suggests they do.

    400 ppm World, Part 1: Large Changes Still to Come

    Why should society care that CO2 is now as high as 400 ppm? The reasons are multiple, but all trace back to the relationship between CO2 and temperature.
