Suzanne O’Connell

Suzanne O’Connell, professor of earth and environmental sciences, received the Exchange Award from the Association for Women Geoscientists at its annual awards breakfast on Nov. 2. The Exchange Award recognizes the contribution of those who exchange technical, education, and professional information in the field.

The award ceremony took place at the Baltimore Convention Center in Maryland in conjunction with the Geological Society of America’s annual meeting. O’Connell is also faculty director of the McNair Program.

According to Blair Schneider, president of the Association for Women Geoscientists, O’Connell won the organization’s Outstanding Educator Award in 2000. Since then, she has been an active member of the group’s Outstanding Educator Award committee, and has continually written articles highlighting the winners for the group’s quarterly newsletter. In explaining O’Connell’s selection for the Exchange award, Schneider pointed to her rare “exemplary teaching” in which she uses “hands-on learning with research for undergraduates.”

“Suzanne is also an incredible supporter of the organization and exchanges information about who we are to her own students and young professionals at every meeting. For example, she pays to bring her own students to the AWG awards breakfast so that they can learn about the organization and see women being recognized for their achievements,” Schneider added.

O’Connell also recently co-edited the publication, “Women in the Geoscience: Practical, Positive Practices Towards Parity.”

 

Varekamp, Gilmore Co-Author Articles on Argentina’s Copahue Volcano

Joop Varekamp, the Harold T. Stearns Professor of Earth Science, professor of earth and environmental sciences, and Marty Gilmore, the George I. Seney Professor of Geology, professor and chair of professor of earth and environmental sciences, are the co-authors of two book chapters published in Copahue Volcano (Springer Publishers, September 2015)

Copahue Volcano is part of Springer Publishers’ “Active Volcanos of the World” series. Varekamp is the lead author on a chapter with Jim Zareski MA‘14 and Lauren Camfield MA’15. Gilmore and Tristan Kading MA’11 are co-authors with Varekamp on another chapter dealing with terrestrial environments as analogs for Mars. A third chapter, on acid fluids, was written by Varekamp with an Argentinian collaborator. 

Since 1997, Varekamp has worked with Wesleyan undergraduate and graduate students almost every year at Copahue Volcano in Argentina. This project is reaching its closing stages, and has led to 10 peer reviewed published articles, most co-authored with students, four book chapters, six MA theses, and eight senior theses. All these students have subsequently obtained higher degrees in E&ES fields and are currently employed in the broad field of geochemistry and/or volcanology. Varekamp is now focussing his studies on the Newberry volcano in Oregon.

Scientist Prager ’84 Speaks to Students about Marine Research, Books

Marine scientist and author Ellen Prager ’84 came to the Exley Science Center on Oct. 8 to talk about her recent research and writing. Discussing her book Sex Drugs and Sea Slime: The Ocean’s Oddest Creatures and Why They Matter, she entertained a crowd of Wesleyan students and faculty with stories from her work in the Galapagos and as researcher at the Aquarius undersea laboratory off Key Largo, Fla. Lately, Prager has ventured into the realm of children’s fiction in order to spread awareness about the ocean’s most pressing issues. Her most recent children’s book, The Shark Whisperer, was published in May 2015.

Peter Patton, the Alan. M. Dachs Professor of Science, professor of earth and environmental sciences, professor of environmental studies, introduced Prager to the audience.

On Sept. 30, NASA’s Discovery Program selected five planetary mission investigations for study during the next year as a first step in choosing one or two missions for launch as early as 2020. Wesleyan’s Martha Gilmore is on two of the investigation teams.

Gilmore, the George I. Seney Professor of Geology and chair of the Department of Earth and Environmental Sciences, is an expert on terrestrial planets. She studies the morphology and mineralogy of the surfaces of Venus and Mars using data from orbiting and landed spacecraft. She also is on the Executive Committee of NASA’s Venus Exploration Analysis Group which identifies scientific priorities and strategy for exploration of Venus.

Each of the five selected investigations will receive $3 million for one year to strengthen their proposed mission by doing in-depth concept design studies. At the end of the year, it is expected that one or two of the mission concepts will then be selected for flight.

“We’re absolutely ecstatic about this opportunity,” Gilmore said. “Venus is key to understanding how Earth-size planets operate in this solar system and in other solar systems. The driving question is why are Venus and Earth so different? Why is Earth the habitable twin planet? The measurements of Venus’ atmosphere and surface proposed by these missions are necessary to better understand the climate, volcanic activity and the habitability of Earth-size worlds.”

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

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.

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.
