Geological Survey (U.S.)

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.

The interview focuses on Pakiser’s training at the Colorado School of Mines, his career in geology and seismology with an emphasis on his crustal studies in the 1960s. During this period Pakiser headed the crustal studies branch of the United States Geological Survey (USGS) and contributed to the Department of Defense’s “Project Vela Uniform,” which aimed at the improvement of seismic detection capabilities.
