Please join us for the Gustaf Arrhenius Symposium, taking place at the International House Great Hall at UC San Diego, just off North Torrey Pines, on Monday, November 4th. The symposium will honor longtime Scripps Oceanography Professor Gustaf Arrhenius and the many contributions he made to our understanding of the origins and limits of life and planetary geochemistry. The program begins at 8:30 a.m. and ends with an evening reception. Please RSVP. Detailed agenda and flyer here.
