  • Joy Crisp '79 Explains Mars Rover's New Findings

    June 6, 2013

    Nasa is finally thinking about getting its Curiosity rover on the road and heading towards the big mountain at its exploration site in Mars' Gale Crater.

    The robot has spent the past six months in a small depression, drilling its rocks and analysing their composition.

    But even as the labs do their analysis, Curiosity has started moving towards a rock feature it saw briefly on the way into Yellowknife Bay.

    Known as Point Lake, this outcrop has an unusual holey appearance - like Swiss cheese. Scientists are unsure as to whether it is volcanic or sedimentary in character.

    "One idea is that it could be a lava flow and those are gas vesicles, and you often see in volcanic rocks on Earth that those kinds of holes are sometimes filled in by secondary minerals. That's one possibility," said Dr Joy Crisp, the deputy project scientist for Curiosity.

  • Luc Mehl '00 Leads A 230-Mile Bike/Hike/Packraft Triathlon

    April 3, 2013

    Windmilling his kayak paddle into the pushy breeze, Luc Mehl, 34, pulls onto the sandbar at the mouth of Mexico’s Rio Antigua and squints at the novelty of a flat, seascape horizon in the hazy afternoon glare. Two days of sleepless dysentery have drained Mehl’s prodigious vigor and his hands are blanched and clammy as we high-five. Still, he’s grinning with accomplishment in the salt air.

    Eleven days earlier we’d set out pedaling bikes strapped with mountaineering and whitewater paddling gear in Cholula de Rivadavia, a ciudad 60 miles east of Mexico City. Without ever having visited Mexico before, Mehl composed a 230-mile bike/hike/packraft triathlon first to Pico de Orizaba (18,491 feet) and then descending through rain forest hamlets to a whitewater river. Now at sea level, we found the end of Mehl’s line.

    Dr. Joseph Colgan '98, a research geologist with the USGS, was named one of President Obama's recipients for the Presidential Early Career Award for Scientists and Engineers, including a reception at the White House. This is the highest honor bestowed by the United States government on science and engineering professionals in the early stages of their independent research careers. Joe was recognized for his work in the Basin and Range.

    Congratulations Joe!

  • Adam Maloof '98 Explains Polar Wandering On Science Friday

    November 9, 2012

    Did you know that Earth's solid exterior can move around over its core, causing the planet's poles to wander back and forth? Adam Maloof, associate professor of geosciences at Princeton University, discusses the consequences of these shifts, and what may be causing them.  [...]

    A new study published in the journal Nature, though, may help explain what causes this colossal slip and slide, and that's what we're talking about next.  [...]

    LICHTMAN: OK. So what are we talking about?

    MALOOF: We're talking about the rest of the Earth: the crust, the rest of the lithosphere and the entire mantle sliding over the outer core. So the way you imagine this is the core of the Earth, the outer part, is actually fluid iron, and it has about the viscosity of water. So we're literally sliding, you know, 2,700 kilometers of mantle over this so that, as perceived from space, what you'd see is the spin axis is staying the same, but all the continents are moving together to a new location.

  • Ross Mitchell '07 Predicts A Future Supercontinent

    February 8, 2012

    Geologists at Yale University have proposed a new theory to describe the formation of supercontinents, the epic process by which Earth’s major continental blocks combine into a single vast landmass. The new model radically challenges the dominant theories of how supercontinents might take shape.

    In a paper published Feb. 9 in the journal Nature, Yale researchers introduce a process called orthoversion, in which each succeeding supercontinent forms 90 degrees from the geographic center of its ancient predecessor. Under the theory, the present-day Arctic Ocean and Caribbean Sea will vanish as North and South America fuse during a mutual northward migration that leads to a collision with Europe and Asia.

    “After those water bodies close, we’re on our way to the next supercontinent,” said Ross N. Mitchell, the Yale doctoral student who is the paper’s first author. “You’d have the Americas meeting Eurasia practically at the North Pole.”

    Opportunity Uncorked: A Mentor Externship in Wine Country!

    California winemaker Jeff Pipes '83 admits that he wasn’t sold on Carleton’s Mentor Externship program at first. Having a student work with him and live with his family sounded like a big commitment.

    "Wine is an intense and competitive industry," explains Pipes, who owns Pipestone Vineyards with his wife, Florence Wong '84. "I’m incredibly busy. Having an extra person around to teach and train takes time."

    But once he began reading applications from eager Carleton students, Pipes couldn't help but be impressed. "There were 30 applications, and I could have happily hired every one of them. They were all great. The hardest part was narrowing it down to just one."

    That "one" turned out to be Amelia Harris '12, an Environmental Studies major with a special emphasis on food and agriculture—a perfect fit for Pipestone Vineyards, where Pipes and Wong strive to practice sustainable agriculture and environmentally friendly farming.
