The Ocean Sciences Award is presented in recognition of outstanding and long-standing service to the ocean sciences community. It is a pleasure to make the 2006 citation for Worth D. Nowlin Jr., Distinguished Professor of Oceanography at Texas A&M University . Worth has, for more than four decades, served as a community leader of mesoscale and large-scale studies of oceanic distributions of properties, the dynamics of ocean circulation, shelf circulation in the Gulf of Mexico, and the development of the coastal module of the Global Ocean Observing System. He has had a tremendous impact on all facets of oceanography and colleagues and students alike.
