Why we are hereWhy we are here

MARGINS, EarthScope, GeoSwath have common interests: identify Formulate key science questions for two critical areas

Use to motivate future plans, proposals Devise strategies to approach, given MARGINS and Earthscope focuses

Immediate Goal: generate short “micro-whitepaper” for rapid publication

This is just a start…

Motivations for cooperative studies

Motivations for cooperative studies

Western U.S. has 1 Focus Site, and critical localities complementary to othersCascadia ls “allied” site: accretionary, young subduction zone

Without Red Sea, should maximize return from (expanded?) GoC/Salton Site

Capitalize on EarthScope Facility… and GeoSwath, and ORION, and …
