  • Discovery By Adam Maloof '98 Adds 70-90 Million Years To The Fossil Record

    August 17, 2010

    In findings that push back the clock on the scientific world's thinking about when animal life appeared on Earth, Princeton scientists may have discovered the oldest fossils of animal bodies, suggesting that primitive sponge-like creatures were living in ocean reefs about 650 million years ago. The shelly fossils, found beneath a 635 million-year-old glacial deposit in South Australia, represent the earliest evidence of animal body forms in the current fossil record by at least 70 million years.

    Princeton geosciences professor Adam Maloof and graduate student Catherine Rose happened upon the new fossils while working on a project focused on the severe ice age that marked the end of the Cryogenian period 635 million years ago. Their findings, published in the Aug. 17 issue of the journal Nature Geosciences, provide the first direct evidence that animal life existed before -- and probably survived -- the severe "snowball Earth" event known as the Marinoan glaciation that left much of the globe covered in ice at the end of the Cryogenian.

  • 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 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.

  • 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.

  • 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.

  • Ben Edwards '89 Studies Interactions Between Glaciers And Volcanoes With Support From NSF

    April 22, 2010

    Glaciovolcanoes, they're called, these rumbling mountains where the orange-red fire of magma meets the frozen blue of glaciers.

    Iceland's Eyjafjallajökull volcano, which erupted recently, is but one of these volcanoes. Others, such as Katla, Hekla and Askja in Iceland; Edziza in British Columbia, Canada; and Mount Rainier and Mount Redoubt in the U.S., are also glaciovolcanoes: volcanoes covered by ice.

    "When an ice-covered volcano erupts, the interplay among molten magma, ice and meltwater can have catastrophic results," says Sonia Esperanca, program director in the National Science Foundation (NSF)'s Division of Earth Sciences, which funds research on glaciovolcanoes.

    In Iceland last week, scientists were well prepared for the floods, called "jökulhlaups," that can happen after a glaciovolcano blows and melts its glacial covering. The floods were followed by tons of ash ejected into the atmosphere.

    Most of the rest of the world, however, was unaware that an eruption from a small, northern island in the middle of the Atlantic Ocean could freeze air transportation and stop global commerce in its tracks.

    That, say NSF-funded scientists Ben Edwards at Dickinson College and Ian Skilling at the University of Pittsburgh, is the nature of glaciovolcanoes.

    Understanding volcano-ice interactions occupies much of Edwards' and Skilling's daily lives.
