Institute (1980-1986). He later turned down the position of Assistant Deputy Minister of Science at the national headquarters of the Department of Fisheries and Oceans (Government of Canada) in favour of a going "back to the bench" as a research scientist. Longhurst has published more than 80 research papers and his most recent books are "Ecological Geography of the Sea" (1st edition 1998, 2nd edition 2007) and "Mismanagement of Marine Fisheries" (2010). He has also written on "Doubt and Certainty in Climate Science" from a personal perspective. In retirement since 1995, he and his wife Françoise run Galerie l'Acadie, a gallery of contemporary art in Cajarc, France. Awards In 1988, Longhurst was elected a Fellow of the Royal Society of Canada. In 1991, he was awarded the Gold Medal by the Professional Institute of the Public Service of Canada for his cumulative influence in the development of Canadian oceanography. In 1997, he received the A.C. Redfield Lifetime Achievement Award from the Association for the Sciences of Limnology and Oceanography "in recognition of sustained excellence in the study of marine food webs and biogeography, and of outstanding leadership in the development of international collaboration and in the administration of world-renowned oceanographic programs". Ecological Geography of the Sea "Ecological Geography of the Sea" is a book on the regional geography of the world ocean for ecologists. According to Longhurst, regional oceanographic processes are paramount in molding the characteristics of regional ecosystems. A central argument of this book is that spatial bounds to ocean ecosystems can be set by reference to features of the physical circulation of the oceans rather than to the distribution of individual species. The root of this approach to a global organisation of the biological seascape is by construction of a typology for seasonal cycles of pelagic production and consumption. The well-known Sverdrup critical depth concept for the induction of phytoplankton growth forced by local mixing and light is the starting point for the seasonal evolution of primary production, and this is very much related to regional oceanography. However, the accumulation or loss of phytoplankton biomass is influenced by secondary processes, such as variation in the size of the herbivore population at the start of the bloom. In extending the Sverdrup model to all parts of the ocean, a typology of plankton cycles is necessary that describes a continuum from strongly seasonal regions with seasonal recharge of photic zone
