David Chapman, Bernstein Geologist-in-Residence, To Focus On Global Warming17 May 2010
The Geology Department is most pleased to welcome Dr. David Chapman of the University of Utah as our 2010 Bernstein Geologist-in-Residence. Dr. Chapman will be here for the whole week, giving talks and participating in classes and other activities of the Geology Department.
Public lecture: Monday, May 17, 7:00 pm., Olin 149
Global Warming: The Science is Settled. What do we do now?
Dr. Chapman writes, “The instrumental record of air temperatures, sea level rise, borehole temperature profiles, and shrinking ice cover in the Northern Hemisphere all indicate that the globe is warming at a rate and extent that is beyond natural variation. The most likely culprit is the growth of greenhouse gases since the Industrial Revolution. Considering the growth of human population, the clear relation between energy use and standard of living, and the fact that we produce about 80% of our energy by burning fossil fuels, we predict a much warmer planet in the future if the current trends are not reversed. There are promising choices for us, however, involving personal, community, national, and international actions. It is not too late.”

“Heat loss of the Earth”
The Earth is losing heat at the rate of 42 Terrawatts. Continental heat flow is well understood but comprises less than 30% of global heat loss. Oceanic heat flow is more complex. Extraordinary geothermal features on mid-ocean ridges (smokers) vent heat at the rate of ~100 Megawatts, but are infrequent in space. More pervasive low temperature hydrothermal circulation through the sea floor out to ages of 50 My, although harder to discern, is responsible for much more heat loss. Modern instrumentation, global positioning, and sophisticated modeling are all parts of the evolving story about how we estimate the heat loss for planet Earth.
Dr. Chapman received his B.S. and M.S. degrees in Physics from the University of British Columbia and then spent six years in Zambia, teaching at Canisius College under the auspices of CUSO (the Canadian Peace Corps) and at the fledgling University of Zambia. His interests then turned to geophysics which he pursued at the University of Michigan, earning his Ph.D. in 1976, after which he joined the faculty of the University of Utah.
Dr. Chapman is also Associate Vice President for Graduate studies and Dean of the Graduate School and Director of Thermal Geophysics Research Group. He leads an active research group studying thermal aspects of geological processes including: global heat flow; thermal state of the lithosphere; geothermal systems; thermal aspects of groundwater flow; thermal histories of sedimentary basins; heat flow and hydrothermal circulation in the sea floor; exhumation of mountain belts; and global warming.
He is author of more than 120 publications including two Scientific American articles, four papers in Nature and one in Science. He has commuted to work for the past 28 years on the same Peugeot 10 speed, enjoys vegetable gardening, and reserves part of each summer for long-distance walking with the recognition that “Britain, France, Italy, and even the High Uintas at 2 miles an hour are just about perfect.”
Watch Bereket Haileab’s Keynote Talk At The 2010 ACM Off-Campus Studies Student Symposium13 May 2010
The speaker at the 2010 Student Symposium on Off-Campus Study was Bereket Haileab, Associate Professor of Geology at Carleton College.
As a geologist, Dr. Haileab mapped volcanic ash deposits used to determine the ages of many early human fossils throughout Kenya and Ethiopia. He has been teaching at Carleton since 1994 and served as the Director of the ACM Tanzania Program in fall 2008.
Nick Holschuh ’11 Is Named Duncan Stewart Fellow26 April 2010
Each year, the geology faculty faces the difficult task of selecting a few students to be Duncan Stewart Fellows. The Duncan Stewart Fellowship was established in 1976 by Daniel Gainey, class of 1949, in honor of Duncan Stewart, professor of geology at Carleton for nearly 25 years.
We select the Stewart Fellows based on a combination of excellence in scholarship, a high level of intellectual curiosity, potential for scientific growth, and involvement in departmental activities. As we make this selection, we realize how fortunate we are to have so many talented, interesting, and impressive students within the department.
We are very pleased to announce that Nick Holschuh ’11 has been named Duncan Stewart Fellow for the next school year, extending the number of Stewart Fellows over the years to 98. Congratulations Nick!
Two Carleton Geology People Awarded NSF Fellowships20 April 2010
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.
19 April 2010
Dr. Elizabeth Screaton, associate professor of geological sciences at the University of Florida, will present “From the Seafloor to the Seismogenic Zone: Fluid Flow in Earthquakes” on Friday, April 23 at 3:30 p.m. in Mudd Hall, Room 73. This event is free and open to the public.
Bryn Benford Returns To Teach Intro1 April 2010
We’re very happy to announce that Bryn Benford, who taught Introductory Geology for us last year, is back again for another round of teaching Introductory Geology this spring term.
Bryn is a Ph.D. Candidate at the University of Wisconsin – Madison. Her thesis, advised by Dr. Basil Tikoff, is entitled, “An integrated tectonic study of the Jamaica strike-slip restraining bend.” Bryn’s masters thesis, also done under Dr. Tikoff’s supervision, was entitled, “Continuation of the Western Idaho shear zone: South Mountain, Idaho.”
Bryn was a geology major and honors student at her alma mater, Franklin and Marshall College.
To keep her sanity and get out of Mudd once in a while, Bryn is also helping coach the Carleton track team in the triple jump and hammer throw events.
Welcome back Bryn!
Science Edcuation Resource Center Honored By The American Association For The Advancement Of Science26 February 2010
A Web site created at Carleton College to make earth science come alive in the classroom has been awarded the Science Prize for Online Resources in Education.
In an era in which knowledge of geoscience is fundamental to handling such pressing issues as climate change and environmental degradation, the Web site, known as On the Cutting Edge, fosters the sharing of ideas about teaching with the aim of improving education throughout the field.
“In the United States, many students get earth science in seventh or eighth grade—and never have another geoscience class,” says Cathryn Manduca, director of the Science Education Resource Center at Carleton College and a co-founder of On the Cutting Edge. “Yet now it is especially important for students in general to understand what is facing us environmentally, and for the workforce to have more and better-trained geoscientists.”
The Science Education Resource Center (SERC) works to improve education through projects that support educators. Although their work has a particular emphasis on undergraduate Science, Technology, Engineering, and Mathematics (STEM) education, they work with educators across a broad range of disciplines and at all educational levels. An office of Carleton College, their work is funded primarily through National Science Foundation grants. The office has special expertise in effective pedagogies, geoscience education, community organization, workshop leadership, digital libraries, website development and program and website evaluation.
We’ve Had A Ton Of Snow This Year!25 February 2010
Julia Schwarz, Laura Bazzetta and Nate Ryan, all class of 2010, horsing around in the epic snow pile behind Mudd. We had more snow this year, and better skiing in the arb, than we can remember in many years.
Paul Riley Helps Out Teaching Tectonics16 February 2010
We’d like to welcome, and thank, Paul Riley, a PhD candidate at the University of Wisconsin-Madison, who stepped in this term to teach Tectonics while Sarah Titus is on sabbatical.
Paul is a 2004 graduate of Franklin and Marshall College’s Geoscience program. His senior thesis was entitled “Shear sense indicators in the Snake Range Decollement, NV,” and he was awarded the Geology Award as an outstanding geology major. Paul’s advisor for his senior thesis was Zeshan Ismat. His masters thesis at the University of Wisconsin, under the supervision of Laurel Goodwin, was entitled “Spatial distribution of deformation bands and fractures in the Pajarito fault zone and implications for vadose zone fluid flow through the Bandelier Tuff, NM.” His PhD thesis, being done under the supervision of Basil Tikoff, is entitled “Characterization and organization of fracture systems in the Tuolumne Intrusive Suite, Sierra Nevada Batholith, CA.”
Along the way, Paul has gained wide-ranging experience including numerous teaching and research positions, grants, awards, and industry experience interning with ExxonMobil last summer.
Paul is also an accomplished marathoner, who for fun ran in a Carleton track meet last weekend and beat all the students in the 5K heat! But being a relatively short race, it called for more of a burst of speed than the long, consistent pace of a marathon, and he says his legs are still sore.
It’s great to have you here Paul!
