  • Bess Koffman '04 Probes Ancient Climates By Melting Ice

    July 20, 2010

    BANGOR, Maine — Bess Koffman is spending her summer watching ice melt.

    But Koffman, 29, of Orono doesn’t stand around a lab at the University of Maine’s Climate Change Institute 10 hours a day monitoring any ordinary frozen H2O.

    Her ice is ancient. Some sections of the ice cores Koffman is melting this summer are 2,000 years old.

    On Tuesday, she spent much of the day looking for evidence of dust in the melting ice from a volcano that erupted in A.D. 186 in New Zealand to see whether it had drifted as far as western Antarctica.

    “It would be new and exciting to document that,” the graduate student said Tuesday morning in a demonstration of her research for Bangor-area news outlets. “This volcanic eruption has not been documented in Antarctica before.”

  • Laura Bazzeetta '10 Wins Outstanding Student Paper Award At AGU

    July 13, 2010

    We are very proud to announce that Laura Bazzetta '10 has received an Outstanding Student Paper Award for her presentation at the 2009 American Geophysical Union fall meeting in San Francisco, California.  Her paper was entitled, "Linking river morphology to larval drift of an endangered sturgeon."

    Good work Laura!!

  • Laura Cleavelenad Peterson '01 Co-authors Ocean-Temperature Paper Published In SCIENCE

    July 12, 2010

    Laura Peterson, Luther College assistant professor of environmental studies, is the co-author of "Tropical Ocean Temperatures Over the Past 3.5 Million Years," a research paper published in the June 18 issue of the journal Science.

    The paper explains the findings of a research project led by Brown University in which Peterson participated. The research team's discoveries that suggest that fluctuating carbon dioxide levels explain why temperatures in tropical oceans and arctic waters have changed together for the past 2.7 million years.

     The research team analyzed cores taken from the seabed at four locations in tropical oceans: the Arabian Sea, the South China Sea, the eastern Pacific Ocean and the equatorial Atlantic Ocean.

  • The Cannon River

    A River Ride to Red Wing

    June 28, 2010

    Rolling north through Northfield and Carleton’s Cowling Arboretum is the Cannon River. Although often enjoyed by sunbathers and fishermen along its banks, many people don’t think of the Cannon as a means of transportation. This spring, three friends and I canoed the Cannon from downtown Northfield—and on to Red Wing, Minnesota, where it joins the mighty Mississippi River. The journey lasted 13 hours and covered an ever-changing tableau of landscapes and wildlife.

  • Ellen Root '07 Explains The Geology Of America's Western Coast

    June 20, 2010

    We are paddling along the western edge of the North American continent, where land meets water. For this week's Notes from the Trail, we asked Ellen Root, our geology expert, to provide us with an explanation of the geology of this region. Here is what she told us:

    You may already know that sea level on Earth changes over time. This depends on temperatures on the whole Earth as well as the amount of ice that is frozen in glaciers and the polar ice caps. At different times in Earth’s history we could have been traveling through what is now land far from the ocean’s edge or among islands that presently lie deep beneath the surface of the water. Today we want to talk about another aspect of the coastline we see each day. We want to look at the rocks that form the support structure for the plants, animals, people, and buildings we have encountered as we paddle along the Canadian coast. Many people think of rocks as solid and immovable, but every day they are moving, very slowly, on a scale so large it can be difficult to comprehend. The science that explains this process is called Plate Tectonics.

    A service of celebration and remembrance for Eiler Henrickson ‘43, Carleton College Charles L. Denison Professor of Geology emeritus, was held during Reunion 2010. The service featured readings, reflections, and music, including a performance by several of Eiler's former students.

    Eiler taught geology at Carleton for 41 years and coached the Carleton wrestling team for 12 seasons. He retired in 1987 and passed away on Dec. 10, 2009.

    See a video of the "Sometime Geology Field Trip Band" performing "Eiler's Schottische" at the June 18 memorial service, along with two short documentary videos by Aleshia Mueller '01, at the Remembering Eiler Henrickson page.

  • Clint Cowan Promoted To Full Professor

    May 25, 2010

    We are extremely pleased to be able to report that the Dean of the College, Beverly Nagel, has just announced faculty promotions for this year, and Clint Cowan '83 is being promoted to full professor effective September 1, 2010.  Congratulations, Clint!

    Professor Clint Cowan was educated at Carleton College and earned his M.Sc. in Geology from The University of Michigan in 1985.   After receiving his Master’s degree, he worked as an exploration geologist with Exxon in Houston, Texas, for two years before entering the Ph.D. program at Queen’s University in Kingston Ontario.  He earned his Ph.D. in 1992, and taught at Carleton for one term as a Visiting Professor before taking a position as an International Staff Geologist with Royal Dutch Shell in The Hague, Netherlands.  Five years later, in the fall of 1997, he returned to Carleton and began his present teaching career.

  • Nate Ryan '10 Is Among New Graduates Who Hunt For Jobs With College's Help

    May 25, 2010

    Northfield, Minn. — College students graduating this spring face one of the toughest job markets in a generation.

    Because of that, career counselors say networking with potential employers is more important than ever.

    That challenge has prompted two Minnesota colleges to become more aggressive in connecting students with alumni who could help them get that first job.

    Nate Ryan is doing his best to find a job, an internship, or anything at all, in this bleak job market. The 23-year-old graduates next month from Carleton College in Northfield.

    Ryan isn't checking classified ads for work, that's so 1990s.

  • Maria Peterson '85 Selected For Kyudo Archery World Cup

    May 7, 2010

    It took her 16 years of discipline and hard practice, but only a handful of people in the world can say they’ve done what Northfield native Maria Peterson accomplished last month.

    Peterson, who practices the Japanese martial art of Kyudo Archery, was one of three Americans selected to represent her country at the first Kyudo Archery World Cup. The first of its kind, the tournament pitted 20 teams from nations around the world against each other in a sport that is equal parts discipline, meditation and athleticism.

    “Kyudo,” which means “the way of the bow” in Japanese, is not necessarily about hitting a target. Instead, practitioners try to attain a zen-like level of calm and control as they fire an arrow from a seven-foot-long bow at a bull’s-eye more than 90 feet away.

    It was that mix of the philosophy and sport that drew Peterson to the activity, which originated in Japan.
