Led by Professor Geoff Abers (speaking above), we organized the Workshop on the Future of the Amphibious Array which was held at Snowbird in the Wasatch Mountains of Utah--and which I remember well from early EarthScope meetings.
The workshop charge was to make the case for further amphibious experiments (emphasizing the idea of crossing the shoreline). We need to articulate the case for integrated amphibious science. And, we were to evaluate the Cascadia experience. We were guided by the EarthScope Science Plan and by the GeoPrisms planning documents. I also helped summarize a breakout session. Here is the PPT.
