Congratulations to Dr. David Applegate, the new director of the US Geological Survey

Dr. David Applegate was confirmed by the US Senate via a voice vote on 4 Aug 2022 to serve as the next Director of the United States Geological Survey (USGS). Dr. Applegate’s appointment as Director builds upon his decades of experience in Earth Science policy and administration.

After receiving degrees in geology from Yale and MIT, including a PhD thesis focused on metamorphic rocks and the geologic evolution of Death Valley, Dr. Applegate switched tracks to a career in Washington DC, with a stint on the Energy and Natural Resources committee, initially as an AGU Congressional Science Fellow. He then worked as the director of government affairs for the American Geosciences Institute before joining the USGS in 2004 as the first Senior Science Advisor for Earthquakes and Geologic Hazards. He next served as Associate Director for Natural Hazards where he led the Coastal & Marine Geology, Earthquake Hazards, Global Seismographic Network, Geomagnetism, Landslide Hazards, and the Volcano Hazards Program. He has served as the interim director of the USGS since January of 2021. Dr. Applegate is also an adjunct professor at the University of Utah where he still occasionally teaches field courses to undergraduates.

Dr. Applegate was the president of the GSW in 2003, and he continues to be engaged in its mission of providing a forum for geological interchange through a program of regularly scheduled formal talks, informal communications, opportunities to meet colleagues, field trips, and public service. The GSW members represent a wide cross-section of the local geologic community.

We would like to extend our congratulations to Dr. Applegate!

Announcement

The National Academies of Sciences, Engineering, and Medicine are looking for nominations for an ad hoc steering committee. The workshop will bring together experts to consider tipping points, cascading impacts, and interacting risks in the Earth system. Nominations from all fields are welcome with expertise in natural, physical, and social and behavioral sciences, including such disciplines as climate science, oceanography, environmental science, economics, engineering, computer modeling and data science, decision support, sociology, and anthropology.

We invite you to submit nominations for this committee by June 3, 2022.

GSW meeting 1578: Draft minutes of meeting for members to evaluate

Please find attached here the draft minutes of the April 27th meeting for members to evaluate. If you have any additions or corrections please email them to our meeting secretary, Beth Doyle, at edoyle[at]nvcc.edu.

Our final Spring meeting (11 May) will be a hybrid meeting, at the Cosmos Club and on Zoom

We will have a full slate of three talks. Join us to learn about the recent exploration of an enigmatic submarine province in the southern Ocean, exoplanets and how their atmospheric properties are revealed, and the rise of oxygen in the Earth’s atmosphere more than 2 Gy ago on the basis of new oxygen isotope studies. If you come to the Cosmos Club, please remember to bring your Covid vaccination card. It will be checked. Non-members are welcome! Details of the talks, including the Zoom link, will be sent to members shortly. Contact Michael Ackerson (ackersonm[at]si.edu) for the Zoom link if you do not have it.

Our 27 April meeting will be a hybrid meeting, at the Cosmos Club and on Zoom

It will feature a full slate of three talks. Join us to learn what super deep diamonds can tell us about the causes of deep focus Earthquakes, about volcanic climate warming, and about the initial analysis of the asteroid Ryugu. If you come to the Cosmos Club, please remember to bring your Covid vaccination card. It will be checked. And don’t forget to save some room for the beer. Non-members are welcome! Details of the talks, including the Zoom link, have been sent to members. Contact Michael Ackerson (ackersonm[at]si.edu) for the Zoom link if you do not have it.

And don’t forget to save some room for the beer. We have a full program of three talks, including a talk about the electrical properties of the terrestrial planets and moons, paleo-perspectives on future sea level projections for the U.S. Atlantic Coast, and finally fractionation and mixing processes in the early Solar System. Details, including the Zoom link, will be sent to members shortly. Contact Michael Ackerson (ackersonm[at]si.edu) for the Zoom link if you do not have it.
