EarthScope and GeoPRISMS Complimentary Research and Joint Planning

By Ramon Arrowsmith, ESNO Director - Summer 2012

A balance between EarthScope-centric data gathering, science, and the interests and capabilities of other complementary communities is valuable. GeoPRISMS’ amphibious investigations of Geodynamic Processes at Rifting and Subduction Margins ( is a strong complement to EarthScope observational and scientific targets. In the last year, GeoPrisms and EarthScope held three joint workshops:

GeoPRISMS - EarthScope Planning Workshop for the Alaska Primary Site Portland, OR, September 22-24, 2011 (

EarthScope - GeoPRISMS Science Workshop for Eastern North America Bethlehem, Pennsylvania; October 27-29, 2011 (

GeoPRISMS - EarthScope Planning Workshop for the Cascadia Primary Site Portland, OR April 5-6, 2012 (

These meetings were attended by many EarthScope scientists. Significant informal and formal consideration of science targets as well as facilities’ planning and management was discussed. The conveners from each of the workshops produced workshop reports full of reviews of the latest scientific results, major research questions, related activities, and opportunities for leveraged efforts with EarthScope (see links above). The workshop reports were distilled into GeoPrisms implementation plans ( which will guide NSF proposal preparation and review. Proponents have begun writing joint Earthscope-GeoPRISMS proposals to the National Science Foundation to pursue joint research at a level and with a perspective difficult for GeoPRISMS or EarthScope activities to accomplish alone.
