The culmination of this research was published in "Antarctic Marine Geology" by Cambridge University Press. Anderson's other research has focused on the evolution of the northern Gulf of Mexico Basin (see Late Quaternary Stratigraphic Evolution of the Northern Gulf of Mexico Margin, Society of Sedimentary Geology Special Publication No. 79), and the response of coastal systems to global change. His most recent book is entitled "The Formation and Future of the Upper Texas Coast" and he recently co-edited a Geological Society of America Special Paper entitled "Response of Upper Gulf Coast Estuaries to Holocene Climate Change and Sea-Level Rise". John received the 1992 GCAGS Outstanding Educator Award, the 1996 Rice University Graduate Teaching Award, 2004 Rice University Presidential Mentoring Award, and was the 2007 recipient of the Society of Sedimentary Research Shepard Medal. He has served as associate editor for Geology, the American Geophysical Union Antarctic Research Series, American Association of Petroleum Geologists Bulletin, Sedimentology, and Marine Geology. He is a Fellow of the Geological Society of America and past president of the Society for Sedimentary Research.
