Reminder of Target Date for GEM Proposals
-----------------------------------------

    The target date for GEM proposals is October 15.  Proposers should 
contact the Program Director, Tim Eastman, regarding any delay beyond this 
date (email to teastman at nsf.gov).  Please give estimated date of receipt 
at NSF.  If at all possible, such delay should not go beyond about one week.

    The official description given in last year's Global Change brochure 
still applies for FY93; the current year brochure became available only 
last week.  Basically, the GEM program will continue to emphasize the Cusp 
and Boundary Layer Campaign with some start for the Tail and Substorm 
Campaign.
