  • Marcia Bjornerud '83 Emphasizes The Risks Of Wisconsin Mine Development

    March 30, 2014

    WISCONSIN has been an environmental leader since 1910, when the state’s voters approved a constitutional amendment promoting forest and water conservation. Decades later, pioneering local environmentalists like Aldo Leopold and Senator Gaylord Nelson, who founded Earth Day in 1970, helped forge the nation’s ecological conscience.

    But now, after the recent passage of a bill that would allow for the construction of what could be the world’s largest open-pit iron ore mine, Wisconsin’s admirable history of environmental stewardship is under attack.  [...]

    Before the passage of the bill, Marcia Bjornerud, a geology professor at Lawrence University in Appleton, Wis., testified before the legislature that samples she had taken from the mine site revealed the presence of sulfides both in the target iron formation and in the overlying rock that would have to be removed to get to the iron-bearing rocks. (When exposed to air and water, sulfides oxidize and turn water acidic, which can be devastating to rivers and streams, along with their fish populations.) Sulfide minerals, Professor Bjornerud said, would be an unavoidable byproduct of the iron mining. But the bill does not mandate a process for preventing the harm from the sulfide minerals that mining would unleash.

  • Deb Goodwin '00 Collects Data To Document The Plastisphere

    January 5, 2014

    SAN DIEGO - Elizabeth Lopez maneuvered a massive steel claw over the side of a 134-foot sailboat and guided its descent through swaying kelp and schools of fish 10 miles off the coast of San Diego. She was hoping to catch pieces of a mysterious marine ecosystem that scientists are calling the plastisphere.

    It starts with particles of degraded plastic no bigger than grains of salt. Bacteria take up residence on those tiny pieces of trash. Then single-celled animals feed on the bacteria, and larger predators feed on them.  [...]

    The plastisphere was six decades in the making. It's a product of the discarded plastic - flip-flops, margarine tubs, toys, toothbrushes - that gets swept from urban sewer systems and river channels into the sea.   [...]

    In October, Goldstein and oceanographer Deb Goodwin of the Sea Education Association in Woods Hole reported that one-third of the gooseneck barnacles they collected from the garbage patch had plastic particles in their guts. The typical fragment measured 1.4 millimeters across, not much bigger than a piece of glitter, according to their report in the journal PeerJ.

    Some of the barnacles had bits of plastic in their fecal pellets too. That finding led Goldstein to speculate that some of the 256 barnacles that were plastic-free when they were captured by researchers had probably eaten plastic at some point in their lives but cleared it from their systems.

    Since crabs prey on barnacles, the plastic the barnacles eat may be spreading through the food web, Goldstein and Goodwin reported.

  • Carleton Geology Alums Honored at GSA Denver

    November 7, 2013

    Carleton Geology would like to celebrate and acknowledge the following alums who were recently recognized at the annual GSA meeting in Denver.

    Philip E. Brown '74 and Kurtis C. Burmeister were awarded the GSA/ExxonMobil Field Camp Excellence Award for their work with the Wasatch-Unita Field Camp.

    The Association for Women Geologists recognized Diane Smith '77, with the Outstanding Educator Award. Diane is the 25th recipient of the award, which was established to "honor teachers who have played a significant role in the education and support of women geoscientists both within and outside the classroom".

    Our very own professor Mary Savina '72, was recognized for her many years of mentoring students and awarded the GeoCUR Undergraduate Research Mentor Award. Read the award letter here.

    The National Association of Geoscience Teachers (NAGT) recognized Scott Linneman '83 for his service for furthering geoscience education with the Bob Christman Award.

    Congratulations friends & keep up the good work!

  • Christine Brick '79 Honored For River Restoration And Water Quality Work

    October 25, 2013

    The Missoula, Montana Conservation Roundtable recognized four local residents for their environmental efforts in the past year.


    Clark Fork Coalition science director Chris Brick was honored with the Arnold Bolle Conservation Professional award. Brick was instrumental in the restoration plans for the confluence of the Blackfoot and Clark Fork rivers when Milltown Dam was removed, as well as work on water quality and ecological health throughout the Clark Fork drainage.

  • Karen Gran '96 Finds Teaching And Learning Opportunities In The Landscapes

    September 19, 2013

    Karen Gran sees what most of us never recognize – how the land changes shape when touched by volcanoes, waves, wind, and rain. She is a geomorphologist, a scientist who seeks to understand landform dynamics through field observations and physical experiments.

    Gran, an associate professor of geological sciences in UMD’s Swenson College of Science and Engineering, often shares her enthusiasm for research with her students, and that process offers UMD students remarkable opportunities.

  • Jeff Mow '81 Named Superintendent Of Glacier National Park

    June 12, 2013

    Jeff Mow, a 25-year veteran of the National Park Service (NPS), has been named superintendent of Glacier National Park in northwestern Montana. Mow, who is now superintendent of Kenai Fjords National Park in Alaska, will begin his assignment at Glacier on Aug. 25.

    Mow, who has led NPS management and stewardship at Kenai Fjords since November 2004, is eager to return to Glacier and Montana. "My first visit to the park was in 1988 as a wild land firefighter on the Red Bench Fire near Polebridge," he recalled. "Twenty-five years later, it is such an honor and privilege to return as superintendent and a newest member of Glacier's outstanding management team. I can't wait to join with the park staff and partners as we meet numerous challenges and opportunities facing the park in the next few years."

  • 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.
