Solid-Earth Geophysics Journal Club/Discussion Group
Unless otherwise noted, we meet Tuesdays at 2PM in the seismology conference room (R-175). All are welcome to attend.
* Please send suggestions of recent GRL, Nature, Science (Geochem/Geophys), Geology, or other short papers for
us to discuss - email Alex: asong@ciw.edu or Wen-che: wcyu@ciw.edu . *
