Thomas’s Microfossil, Climate Change Research Published in 2 Journals

Ellen Thomas

Ellen Thomas

Ellen Thomas, the University Professor in the College of Integrative Sciences, research professor of earth and environmental science, is the co-author of two recently published papers. They include:

Microfossil evidence for trophic changes during the Eocene–Oligocene transition in the South Atlantic (ODP Site 1263, Walvis Ridge),” published in Climate of the Past, Volume 11, pages 1249–1270 in September 2015 and “Changes in benthic ecosystems and ocean circulation in the Southeast Atlantic across Eocene Thermal Maximum 2,” published in the journal Paleoceanography, Volume 30, pages 1059-1077 in August 2015.

“Microfossil evidence” describes changes in organisms living in the oceans during a major change in the earth’s climate, a period of global cooling about 33.7 million years ago, when the Antarctic ice sheet first became established. The seven co-authors are all women, including former Wesleyan graduate student Raquel Fenero.

The researchers examined the biotic response of calcareous nannoplankton to environmental and climatic changes during the Eocene–Oligocene transition at Ocean Drilling Program (ODP) Site 1263 (Walvis Ridge, southeast Atlantic Ocean). During this time interval, global climate, which had been warm under high levels of atmospheric CO2 during the Eocene, transitioned into the cooler climate of the Oligocene.

In the Paleoceanography article, Thomas and her co-authors describe changes in benthic ecosystems in the oceans during a short period of global warming about 53.7 million years ago, and the effects of loss of oxygen and ocean acidification. The researchers include climate and geochemical modeling to indicate that changes in ocean circulation due to warming triggered more profound effects on living organisms at some depths than at other depths, and that the response of life forms to global warming (including feedback effects) thus may be complex. This article is the result of research done during Thomas’s stay as Leverhulme Visiting Professor at the University of Bristol in the United Kingdom, where she co-supervised graduate student Suzy Jennions.

“Our combined ecological and modeling analysis illustrates the potential role of ocean circulation changes in amplifying local environmental changes and driving temporary, but drastic, loss of benthic biodiversity and abundance,” Thomas said.

In this News @ Wesleyan story, we speak with Robert Ramos from the Class of 2016.

Q: Robert, where are you from and what is your major?

A: I’m from Philadelphia, and I’m a biology and earth and environmental sciences double major.

Ramos explained how the ship's sonar equipment works.

Ramos explained how the ship’s sonar equipment works.

Q: This summer you did a SEA Semester program, “Aloha ‘Aina: People & Nature in the Hawaiian Islands.” How did you become involved in the program?

A: I learned about the program from another Wesleyan student who had done it a few years ago. As a biology and E&ES double major, it sounded like it was right up my alley! At the time, I was thinking about how I was going to apply my studies—what I wanted to do with the rest of my life. This seemed like a good opportunity to explore new options.

SEA Semester does programs at sea all over the world. This summer just happened to be the trip to Hawaii, and I was very excited to go there! I also didn’t want to miss out on a whole semester on campus at Wesleyan, so this worked out well in that it was just five weeks in the summer.

Q: Please give us an overview of how you spent those five weeks.

A: I took two classes—on oceanography and marine policy—and did research on topics like ocean salinity, temperatures and currents.

Suzanne O’Connell

For her distinguished contributions to the geosciences, Suzanne O’Connell, professor of earth and environmental sciences, recently became a Fellow of the Geological Society of America.

Society Fellowship is an honor bestowed on leading professional geoscientists. New fellows are nominated by existing GSA fellows in recognition of their contributions to the geosciences through such avenues as publications, applied research, teaching, administration of geological programs, contributing to the public awareness of geology, leadership of professional organizations, and taking on editorial, bibliographic and library responsibilities.

“Suzanne O’Connell is an accomplished geoscientist who highly honors the traditions of research and scholarship in the geosciences, but also pays great attention to the societal well-being of the community, reflected by her service in professional societies, her work in policy, and her persistent and caring attention to students,” said GSA fellow and nominator Marilyn Suiter MA ’81.

At Wesleyan, O’Connell teaches courses in the geosciences

O’Connell Edits Book that Focuses on Women in the Geosciences

womeningeosciencesSuzanne O’Connell, professor of earth and environmental sciences, is the co-editor and co-author of the book, Women in the Geosciences: Practical, Positive Practices Toward Parity, published in May 2015 by Wiley and the American Geophysical Union.

The geoscience workforce has a lower proportion of women compared to the general population of the United States and compared to many other STEM fields. This volume explores issues pertaining to gender parity in the geosciences, and sheds light on some of the best practices that increase participation by women and promote parity.

Highlights include lessons from the National Science Foundation-ADVANCE; data on gender composition of faculty at top earth science institutions in the U.S.; implicit bias and gender as a social structure; strategies for institutional change; dual career couples; family friendly policies; the role of mentoring in career advancement for women; recruiting diverse faculty and models of institutional transformation.

O’Connell’s chapters are titled “Multiple and Sequential Mentoring: Building Your Nest”; “Learning to Develop a Writing Practice“; “Hiring a Diverse Faculty”; and “Lactation in the Academy: Accommodating Breastfeeding Scientists.”

O’Connell also is the faculty director of the McNair Program.

7 Faculty Promoted, 1 Awarded Tenure

In its most recent meeting, the Board of Trustees conferred tenure on Hari Krishnan, associate professor of dance. He joins seven other faculty members who were awarded tenure earlier this spring.

In addition, seven faculty members were promoted to Full Professor: Mary Alice Haddad, professor of government; Scott Higgins, professor of film studies; Tsampikos Kottos, professor of physics; Edward Moran, professor of astronomy; Dana Royer, professor of earth and environmental sciences; Mary-Jane Rubenstein, professor of religion; and Gina Athena Ulysse, professor of anthropology.

Brief descriptions of their research and teaching appear below.

Associate Professor Krishnan teaches studio- and lecture-based dance courses on Mobilizing Dance: Cinema, the Body, and Culture in South Asia; Modern Dance 3; and Bharata Natyam.  His academic and choreographic interests include queering the dancing body, critical readings of Indian dance and the history of courtesan dance traditions in South India. He is a scholar and master of historical Bharatanatyam and also an internationally acclaimed choreographer of contemporary dance from global perspectives.

Professor Haddad teaches courses about comparative, East Asian, and environmental politics. She has authored two books, Building Democracy in Japan and Politics and Volunteering in Japan: A Global Perspective, and co-edited a third, NIMBY is Beautiful: Local Activism and Environmental Innovation in Germany and Beyond. She is currently working on a book about effective advocacy and East Asian environmental politics.

Professor Higgins teaches courses in film history, theory, and genre, and is a 2011 recipient of Wesleyan’s Binswanger Prize for Excellence in Teaching.  His research interests include moving-image aesthetics, feature and serial storytelling, and cinema’s technological history. He is author of Harnessing the Rainbow: Technicolor Aesthetics in the 1930s and Matinee Melodrama: Playing with Formula in the Sound Serial (forthcoming), and editor of Arnheim for Film and Media Studies.

Professor Kottos offers courses on Quantum Mechanics; Condensed Matter Physics; and Advanced Topics in Theoretical Physics. He has published more than 100 papers on the understanding of wave propagation in complex media, which have received more than 3,000 citations. His current research focuses on the development of non-Hermitian Optics. This year, the Air Force Office of Scientific Research has recognized his theoretical proposal on optical limiters as a high priority strategic goal of the agency.

Professor Moran teaches introductory courses such as Descriptive Astronomy and The Dark Side of the Universe, in addition to courses on observational and extragalactic astronomy.  His research focuses on extragalactic X-ray sources and the X-ray background, and his expertise in spectroscopic instrumentation combined with an insightful conceptual appreciation of galaxy formation have positioned him as a leader in observational black hole research.

Professor Royer offers courses on Environmental Studies; Geobiology; and Soils.  His research explores how plants can be used to reconstruct ancient environments, and the (paleo-) physiological underpinnings behind these plant-environment relationships.  His recent work on the relationship between atmospheric carbon dioxide levels and climate over geologic time has had significant impact on the field of paleoclimatology.

Professor Rubenstein teaches courses in philosophy of religion; pre- and postmodern theologies; and the intersections of religion, sex, gender, and science.  Her research interests include continental philosophy, theology, gender and sexuality studies, and the history and philosophy of cosmology.  She is the author of Strange Wonder: The Closure of Metaphysics and the Opening of Awe, and Worlds without End: The Many Lives of the Multiverse.

Professor Ulysse offers courses on Crafting Ethnography; Haiti: Between Anthropology and Journalism; Key Issues in Black Feminism; and Theory 2: Beyond Me, Me, Me: Reflexive Anthropology. Her research examines black diasporic conditions. Her recent work combines scholarship, performance, and exposition to ponder the fate of Haiti in the modern world and how it is narrated in different outlets and genres.  She is the author of Downtown Ladies: Informal Commercial Importers, A Haitian Anthropologist and Self-Making in Jamaica, and Why Haiti Needs New Narratives.

Johan “Joop” Varekamp, the Harold T. Stearns Professor of Earth Science, professor of earth and environmental sciences, was elected to be chair of the Geology and Public Policy Committee (GPPC) of the Geological Society of America (GSA). The group prepares position statements for GSA (e.g., on fracking, climate change). Varekamp has already made six congressional visits in March, visiting the offices of Senators Richard Blumenthal, Elizabeth Warren, Ed Markey and Representative Rosa DeLauro. He does similar work as chairman of the board of the Connecticut Fund for the Environment / Save the Sound.

Varekamp also was elected to be the chair of the LimnoGeology (‘lakes’) division of GSA for the next two years, which involves organizing conferences and sessions at annual GSA meetings, and editing special volumes on lakes.

In addition, Varekamp received funding through the Keck Geology Consortium for a research project on the two crater lakes of Newberry volcano in Oregon. Varekamp will visit the lakes this summer with a group of student researchers from Wesleyan, Amherst, Colgate and Smith College.

Resor, Seixas ’10 Co-Author Paper on Structural Mapping of Hualapai Limestone

Phil Resor, associate professor of earth and environmental sciences, and Gus Seixas ’10 are co-authors of “Constraints on the evolution of vertical deformation and Colorado River incision near eastern Lake Mead, Arizona, provided by quantitative structural mapping of the Hualapai Limestone,” published in the February 2015 issue of Geosphere, Vol. 11, pages 31-49. The paper includes research from Seixas’s honors thesis at Wesleyan.

In this study, the authors quantify the structural geometry of Hualapai Limestone, which was deposited in a series of basins that lie in the path of the Colorado River. The limestone was deformed by by a fault pair known as the Wheeler and Lost Basin Range faults.
