It’s a special honor for me to be with you this evening to present the Fifth Annual Roger Revelle Commemorative Lecture. The highly respected Dr. Revelle made so many significant contributions in oceanography, and his vision for “blue water” research was instrumental in making Scripps the oceanographic powerhouse it is today, including the RV Roger Revelle, a research ship that has taken so many teachers and students out to sea. And, like me, he was an old salt, having served in the Naval Reserve and then in the regular Navy during WWII until 1948 when he returned to Scripps after completing his service as head of the Office of Naval Research’s Geophysics Branch. As a submariner and as the Chief of Naval Operations, I fully appreciated, and the Navy benefited from, his unique contributions to advancing our knowledge of the oceans and the seafloor. Roger and his colleagues helped us win the Cold War.
