Feed Your Brain—Lunchtime Enlightenment

Michel T. Halbouty Distinguished Lecture Tom Gleeson Mon., 26 Oct., 12:15–1:15 p.m. “Is Groundwater a Local and Global Resource? New Sustainability Ideas and Tools across Scales.”

Groundwater resources are the most reliable source of freshwater on the planet, so long as they are sustainably managed. While serious groundwater depletion and contamination are well docu- mented in several regions around the world, other regions have the potential to leverage under- developed groundwater resources to fuel local human development. In his lecture, Gleeson will Tom Gleeson argue for the importance of global perspectives on groundwater governance and management, introduce a recent global groundwater sustainability initiative, and highlight research on new tools for protecting environmental flows from local groundwater pumping.

32 GSA Today | July 2020 Circum-Arctic Structural Events: Tectonic Evolution of the Arctic Margins and Trans-Arctic Links with Adjacent Orogens Edited by Karsten Piepjohn, Justin V. Strauss, Lutz Reinhardt, and William C. McClelland The circum-Arctic region has received considerable attention over the past several decades with vigor- ous debate focused on topics such as mechanisms for opening the Eurasian and Amerasian basins, the importance of plume-related magmatism in the devel- Special Saper SSS opment of the Arctic Ocean, and mechanisms for ancient terrane translation along the Arctic mar- gins. In recognition of the 25th anniversary of the Circum-Arctic Structural Events (CASE) program, an international polar research effort organized Tectonic Eoltion o the Arctic Mrgins n TrnsArctic ins ith Acent Orogens and led by the Bundesanstalt für Geowissen- schaften und Rohstoffe (BGR) of Germany, this Sircum-Srctic Structural Svents volume presents results from 18 major field expeditions involving over 100 international Sircum-Srctic Structural Svents: ith Acent Orogens Tectonic Eoltion o the Arctic Mrgins n TrnsArctic ins geoscientists from a broad spectrum of disci- plines. The resulting publication focuses on the Proterozoic to Cenozoic tectonic evolution of the circum-Arctic region with correlations to adjacent orogens.

The resolution of this question requires a continent-wide perspective on tec- tonics through time, and it requires the inte- gration of many fields of geoscience. One way to approach the question is to ask (1) what is the holistic geological character of Laurentia at particular times in Earth his- tory?; and (2) what are the apparent control- ling factors at those times, from mantle dynamics to plate interactions, to surface weathering, to biological evolution? The GSA 2020 Annual Meeting provides an opportunity to address the tectonic evolu- tion of Laurentia and the evolution of tectonic processes in general as an international geo- Figure 1.
