The Theoretical and Experimental Institute (TEI) for the Subduction Cycles and Deformation (SCD) initiative is held on the three full days of October 12-14 and is intended to provide a summary of progress made in the science objectives of the SCD initiative (as discussed in the Science and Implementation plan available through geoprisms.nineplanetsllc.com). Applicants do not have to have worked on projects funded by GeoPRISMS. We expect a broad and diverse audience drawn from domestic and international researchers, including graduate students and early career scientists, who are interested in the structure and dynamics of subduction zones.
Funding
The TEI is funded by the National Science Foundation through the GeoPRISMS Office at the University of Michigan. There is no registration fee. Due to space restrictions the meeting will be strictly limited to 150 participants. We will be able to cover on-site expenses (venue costs, hotel expenses based on double occupancy, and breakfast+lunch) for up to 120 participants. Most participants will have to cover travel to and from the meeting. Partial funding for travel is available for students and postdocs. We will not be able to provide dinner on-site but there are plenty of restaurants nearby.
Confirmed participants whose on-site expenses are covered are expected to arrive on Sunday afternoon and leave on Thursday morning.

Sunday October 11, 2015
On Sunday before the meeting we will hold a student and postdoc symposium which will feature short presentations by the attendees and discussion with the conveners and NSF program managers. The meeting starts at 3 pm. We encourage all students and postdocs to attend and to arrange their travel accordingly, after confirmation of attendance.

Discussion (Peter van Keken)
A field trip (led by Sarah Penniston-Dorland) will be organized on Santa Catalina Island on Thursday October 15. This will give participants the opportunity to see amphibolite- and blueschist-facies rocks that have been exhumed from a paleosubduction zone. There is no NSF funding for this trip and participants will need to cover all expenses. We estimate that the cost (including transport from hotel to ferry terminal, ferry ride, transport on Catalina, breakfast and lunch; accommodation at the Portofino for one more night) is around $400-$500 per person. The departure time from the hotel (to catch the first ferry to the island) will be at 5:15am. Cost for participants who do not require an additional night of accommodation will be adjusted. Capacity for the field trip is limited and we will confirm participants on a first-come, first-served basis after receipt of payment.
