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.

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.

We have just learned that Nate Evenson ’10 was recognized for the “Outstanding Undergraduate Oral Presentation” at this spring’s Cordilleran Section of the Geological Society of America meeting in Anaheim, California. Nate’s title was, “U-Pb zircon geochronology and provenance of the Paleogene–Neogene Kootznahoo Formation, southeast Alaska.” The award includes a check for $400.

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.

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.

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.

An announcement from the Geological Society of America tells us that Larry Meinert '75 has been selected as the GSA-USGS Congressional Science Fellow for 2010–2011. Larry is a professor in residence in the geology department at Smith College and editor-in-chief of the Journal of Economic Geology. He earned a B.A. in geology from Carleton College and a Ph.D. in geology from Stanford University, and is recipient of the 2010 Silver Medal from the Society of Economic Geologists.
Larry recently gave us his own version of the story: "After seven years at Smith College in Massachusetts following 22 years at Washington State University, I am moving on to 'the other Washington.' I will be the Geological Society of America Congressional Fellow for 2010-2011. Since 2008 I have been the editor of Economic Geology, which is another full time job on top of my other three (I also run a small winery specializing in a Bordeaux blend of Cabernet Sauvignon, Merlot, Carmenere, and Malbec). In October, 2009 I ran my first marathon, in St. George, Utah. I finished without killing myself and was very pleased to have run sub-four hours (3:56:04)."

We are proud to report that two Carleton geology majors have been awarded National Science Foundation graduate research fellowships! The fellowships provide graduate students with three years of support worth a total of over $100,000. The fellowships carry annual stipends of $30,000 plus a one-time allowance of $11,500 for education-related expenses.
Among the ten winners of fellowships this year from Carleton were two Carleton geology majors: Kristin Bergmann ’04, who is attending the California Institute of Technology and Sam Kanner ’10, who will be attending the University of California-Berkeley.
Also, the eight honorable mentions in the competition from Carleton included geology alums Tyler Mackey and Lydia Staisch, both '08.

Though it’s generally understood that any landscape changes over time—particularly as the number of people it supports increases—these changes occur over such a span of time that they go more or less unnoticed. With The Changing Arctic Landscape, photographer Ken Tape sets changes in the landscape in stark relief, pairing decades-old photos of the arctic landscape of Alaska with photos of the same scenes taken in the present.

In 1981, history professor James Olson was diagnosed with epitheliod sarcoma and in 2000, with brain cancer. As a cancer patient, he endured radiation therapy, chemotherapy, brain surgery, and amputation of his left forearm. He uses his own ordeal as an illustrative example in Making Cancer History, a meticulous history of the institution where he was treated: the University of Texas M.D. Anderson Cancer Center.
