Please note the following:1. If your announcement involves a deadline within one week, our regular distribution schedule may not be able to include your announcement in time. Please contact the Editor (firstname.lastname@example.org) if you need assistance.2. Due to the large number of SPA-related sessions at major conferences, the SPA Newsletter can no longer accept announcement requests for individual sessions at AGU, AOGS, COSPAR, EGU, or IAGA Meetings. Titles and web links (if available) of these sessions will be distributed in a special issue of the Newsletter before the abstract deadline.3. Back issues are available at: http://spa.agu.org/category/newsletters/.To subscribe to the newsletter, please go to the web page at http://lists.igpp.ucla.edu/mailman/listinfo/spa.
