Olivia DrakeBarry Chernoff and Dana Royer are the co-authors of "Diversity in neotropical wet forests during the Cenozoic linked more to atmospheric CO2 than temperature," published in the Proceedings of the Royal Society, B, in 2013. Proceedings B is the Royal Society's flagship biological research journal, dedicated to the rapid publication and broad dissemination of high-quality research papers, reviews and comment and reply papers. The scope of the journal is diverse and is especially strong in organismal biology. Chernoff is the director of the College of the Environment, the Robert Schumann Professor of Environmental Studies, professor of biology, professor of earth…

Kate Shervais '13 presented her thesis research on "Examining Microroughness Evolution in Natural and Experimental Pseudotachylyte-bearing Fault Surfaces," at the European Geosciences Union General Assembly in April. More than 11,000 scientists from 95 countries attended the conference, which was held in Vienna, Austria. Only 28 percent of the participants were students. Shervais completed her study with Phil Resor, associate professor of earth and environmental sciences. Resor, who received a National Science Foundation grant to study earthquakes in an Italian fault zone, also attended the conference. The NSF grant supported their travel to the conference. "I had a wonderful time and…
Lily Baggott '15Plate subduction, magmatism, and mantle plumes are the focus of a recent study by Christopher Kincaid ’83, professor of oceanography at the University of Rhode Island. A highly contested topic, the three proposed causes of volcanism in the northwestern United States led Kincaid and his team aboard the RV Endeavor to publish an article in the scientific journal Nature. “I always tell people that I got on this track to being an oceanographer because of my time at Wes,” Kincaid said. “I can trace it back to taking small geology classes alongside master’s level grad students. It made a huge…
Ellen Alexander '14, Professor Joop Varekamp and graduate student Lauren Camfield recently returned from Argentina where they studied the eruptive products of the Copahue volcano March 7-March 19. Varekamp, the Harold T. Stearns Professor of Earth Science, professor of environmental studies, has studied the volcano since 1997. It erupted in 2000 and again in December 2012. "Many Wesleyan students have done their senior theses and grad theses on Copahue. It's exciting stuff for us volcanology types," Varekamp said. Camfield sampled the products of the most recent eruption of Copahue, which included ash, pumice and volcanic bombs. She will analyze her samples…
Kim Diver, visiting assistant professor of earth and environmental sciences, received an $18,500 grant from the KECK Geology Consortium on Jan. 15. The award will support an undergraduate research program on "GIS Approach to Water-Level Change: Potential Effects of Water-Level Changes on Island Ecosystems," this summer.
The Wesleyan Weather Station recorded a strong drop in local air pressure during Hurricane Sandy on Oct. 29. According to the weather report, the local sea-level barometric pressure was a normal 760 mmHg (millimeters of Mercury) on Oct. 28. When Hurricane Sandy passed through Wesleyan's campus on Oct. 29, the pressure dropped to a low of 733 mmHg during the storm's peak. "Low pressure generally indicates stormy conditions whereas high pressure is associated with fair weather," explains Johan "Joop" Varekamp, the Harold T. Stearns Professor of Earth Science. "We tend to only see the barometer drop this low in the…
(Story contributed by Jim H. Smith) Senior thesis research conducted last spring by Audrey Haynes '12 at Costa Rica’s National University, under the tutorship of Johan “Joop” Varekamp, has shown that many residents of the Central American nation have levels of mercury in their hair that far exceed those recommended by the U.S. Environmental Protection Agency. Varekamp, whose student made the discovery as part of a broad evaluation of environmental mercury in Costa Rica, says the elevated mercury levels are probably a consequence of over-consumption of large ocean fish, not exposure to mercury in the air emitted by volcanoes, as…
By looking at high-resolution images captured by the Mars Reconnaissance Orbiter, scientists are able to see gullies, which are argued to be geologically recent. Because they are most likely formed by water, it is believed that they can answer the question of whether or not there is still "active" water on Mars. As a summer Wesleyan McNair scholar, astronomy major Lavontria Aaron '14 used a hyperspectral instrument to determine if the gullies contained minerals (salts) which would be left behind by water brines. "By examining the spectrum of the brines, we'll be able to learn more about Mars' history and…
David PesciEllen Thomas, research professor of earth and environmental sciences, has been awarded the Maurice Ewing Medal by the American Geophysical Union (AGU). The medal is one of the AGU’s most prestigious awards and will be presented to Thomas during the organization’s annual meeting later this year. According to AGU, “Jointly sponsored with the United States Navy, the Ewing Medal is named in honor of Maurice Ewing, who made significant contributions to deep-sea exploration.” It is presented each year for significant original contributions to the scientific understanding of the processes in the ocean; for the advancement of oceanographic engineering, technology, and…
A new study designed to give scientists a better understanding of how earthquakes occur by studying ancient faults long after the quakes are over will be led by a Wesleyan faculty member and involve at least two of his students. Phillip Resor, assistant professor of earth and environmental sciences, received a $246,728 NSF (National Science Foundation) grant for his study titled “Three Dimensional Characterization of a Pseudotachylyte-bearing Fault.” The grant includes funding for one thesis student for each of the next two years; Wesleyan has contributed additional funding for a second student in 2012. The study will also establish a…
