CIDER Summer 2016 group photo

CIDER 2016 pre-AGU Workshop

Sunday, December 11, 2016, 9:00 am to 5:00pm
Location: University of California, Berkeley, Saturdja Dai Hall,
Banatao Auditorium, Room 310

The CIDER-II Synthesis Center proposal to the NSF/FESD program has been funded for 5 years starting in summer 2012. We are continuing the summer programs, which are now held every year, alternating "deep" and "shallow" earth themes. We have been launching new activities, among which support for multi-disciplinary working groups on targeted topics, more sustained support for student research groups formed during the summer programs, a CIDER wiki and archival of materials assembled during the summer programs, as well as an annual one day workshop held in Berkeley either right before or right after the Fall AGU meeting.

This one day workshop will serve as a kick-off for the CIDER 2017 Summer Program, on the topic of "Subduction zone structure and dynamics" and a retrospective on past programs, in particular, the most recent 2016 summer Program


The workshop will feature 30 mn talks by 4 keynote speakers (two on themes related to the 2015 CIDER summer program and two on themes related to the 2016 CIDER summer program) as well as presentations by research groups from the 2015 and prior programs.

Keynote Speakers:

  • Maureen Long (Yale U.):"Constraints on flow in the deepest mantle from seismic anisotropy and other observations"
  • Thorsten Becker (U.T. Austin):"Challenges to our understanding of global mantle convection"
  • Jeff Freymueller (Univ. of Alaska): "Subduction Megathrust Slip Processes and Deformation"
  • Adam Kent (Oregon State U.): "Constraints on subduction zone structure and processes from volcanic rocks: melting, mixing and MASHing"

The workshop is open to all - we encourage attendance by both former CIDER junior and senior participants, and those that haven't experienced CIDER yet but would like to find out more about it.

Workshop Organizers: Barbara Romanowicz, Marc Hirschmann and the CIDER ExCom.
