Dr. Robert Spies served as the Chief Scientist for the Exxon Valdez Oil Spill (EVOS) Trustee Council between 1989 and 2002. Recently, Dr. Spies oversaw the compilation and synthesis of the significant results from twelve years of post-spill study of the EVOS damage assessment and restoration programs as they relate to anthropogenic and natural forcing factors that operate in the northern Gulf of Alaska. The results of the synthesis appear in a book published by Elsevier Scientific, Long-term Ecological Change in the Northern Gulf of Alaska: http://www.elsevier.com/wps/find/bookdescription.cws_home/710080/description#description
