Plate tectonics

This is a three-part interview with Sir Robert S. J. Sparks, the Chaning Wills Professor of Geology in the Department of Earth Sciences at the University of Bristol. The interview begins with anecdotes from Sparks’ childhood and memories of undergraduate geological field trips while at Imperial College. He recalls the influences of John Ramsay and George Walker, the latter of whom became his PhD advisor. Sparks discusses Walker’s emphasis on writing and publishing, and he talks about some of his early publications. Sparks then describes his time in the U.S. at the University of Rhode Island, describing key differences between the scientific communities in the U.S. and Europe. The second session focuses on Sparks’ time at Cambridge, his teaching philosophy, and the culture within the Earth Sciences department at Cambridge. He discusses the different funding opportunities he secured from the NSF, NERC, and BP. Sparks recalls his sabbatical in Australia and recounts the factors leading to his appointment at Bristol. In the third session, Sparks reflects on his most influential papers over the years, as well as changes he has witnessed within Bristol’s earth sciences department. He discusses his involvement in the Royal Society and American Geophysical Union, as well as his time as President of both the Geological Society of London and the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI). The interview concludes with Sparks’ reflections on the many accolades he has received in his career and his thoughts on the role of scientists as public intellectuals. 

Interview with Dr. Anne Grunow, Senior Research Scientist at the Byrd Polar and Climate Research Center and curator of the Center’s Polar Rock Repository at the Ohio State University. Grunow describes her childhood in Southern New Jersey where her father was a potato farmer and her mother was a schoolteacher. She recalls helping out on the farm throughout her childhood. Grunow discusses her initial enrollment at Lehigh University for her undergraduate studies and her eventual transfer to Wellesley College where she studied geology. She describes her summer internship at Chevron before beginning her graduate studies at Columbia University, studying with Ian Dalziel. Grunow talks about her time at Columbia University's Lamont-Doherty Geological Observatory and her field work in South America and Antarctica. She also reflects on being the only woman or first woman on many of her Antarctic expeditions. Grunow discusses her NATO post-doctoral fellowship at the University of Oxford as well as another post-doc that led her to Ohio State University. The interview concludes with Grunow’s involvement in the establishment of the Polar Rock Repository and her general reflections on how the field has changed over time.

In this interview, Marcia McNutt discusses: current position as President of the National Academy of Sciences (NAS) in Washington, D.C.; mission, history, and structure of the NAS; NAS’s work on climate change and COVID-19; experience as a geophysicist; partnering with the National Academies of Engineering and Medicine; childhood in Minnesota; decision to study geophysics; graduate research at Scripps Institution of Oceanography; research on ocean island volcanism in French Polynesia and Hawaii; early use of magnetometers, gravity meters, and seismometers in oceanic plate tectonic observation; development of techniques to take gravity, bathymetry, or topography data on continent and use them in inversion to learn about topography; work directing Monterey Bay Aquarium Research Institute (MBARI); time at US Geological Survey (USGS) under Ken Salazar; professorship at MIT and collaboration with Woods Hole; details of leading an oceanographic expedition in the Marquesas Islands; spearheading structural change at MBARI; MBARI-created autonomous device to identify microscopic ocean life without samples; MBARI-invented deep-sea laser Raman spectrometer; being the first organization to put AI on autonomous underwater vehicles to map plumes; response to the Deepwater Horizon spill; fracking; the National Water Census; decision to become editor-in-chief of Science; procedures as editor; career evolution; becoming president of NAS; transition from the Obama to Trump administrations; opinions on geo-engineering; Decadal survey; Koshland Science Museum and LabX; efforts to nominate and elect younger scientists and underrepresented minorities to the Academy; making recommendations to Congress; collaborations with the private sector; communication with the public; and the 2018 Committee on Women in Science, Engineering, and Medicine’s report on sexual harassment in academia. Toward the end of the interview, McNutt reflects on her career as both scientist and leader and the importance of integrity in research.

Interview with G. Brent Dalrymple, Dean and Professor Emeritus at Oregon State University. Dalrymple recounts his childhood in Los Angeles, and he explains how he settled on geology as a major at Occidental and the impact of the plate tectonics revolution that was happening at the time. He discusses his graduate work at Berkeley, and he recounts his field work under the direction of Garniss Curtis on potassium argon dating. Dalrymple explains his decision to join the U.S. Geological Survey after graduate school and his interest in learning more about volcanic rocks and magnetic fields in the Sierra range. He explains how this research solved the problem of continental drift and he discusses his subsequent research on the Hawaiian Island range. Dalrymple discusses his work on earthquake detection, and he describes the advances in K-Ar dating and techniques. He discusses his work on meteorite dating and the light this shed on what killed off the dinosaurs, and he describes his advisory work for the Apollo missions. Dalrymple explains how he became involved in debates with religious communities who insisted the age of the Earth was 6,000 years old and how this turned into his book The Age of the Earth. He describes how geo-dating is relevant for understanding star and galaxy formation and he discusses his tenure as president of the American Geophysical Union. Dalrymple describes what it was like to win the National Medal of Science, and he explains his decision to retire from the USGS and join the administration at Oregon State. At the end of the interview, Dalrymple describes the impact of continental drift research, and he conveys his enjoyment with life in retirement.
