Perhaps the greatest turning point in my life came when I was in high school and I wrote a letter to the famous Scripps Oceanographic Institution, asking how I might learn more about the sea．A kind scientist answered my letter and told me how to apply to Scripps for a summer scholarship, which I received．During one of their courses that summer, I met Dr．Robert Norris, a marine geologist．He loved the sea almost as much as I did．Soon he suggested I consider his school, the University of California, for my study．One year later I became a member of the freshman class．

　　Now my love affair with the sea became a serious endeavor．If I wanted to be an undersea explorer, I needed to lea as much as I could about the laws of the physical world that controlled the environment I wanted to enter．The undersea world is not our natural world．It is unforgiving to those who make mistakes．At its greatest depths the water temperature is near freezing, the pressure is eight tons per square inch, and it is totally dark．It is easy to get lost in such a world．I needed to lea a lot about geography, navigation, geology, biology, and many other things．

　　I decided another important thing for me to do was to join the U．S．Navy．If I was going to be an undersea explorer, I would have to lead men and women on dangerous adventures where they might get hurt, and I didn't want that to happen．

　　In the Navy I learned discipline, organization, and how to motivate and lead people on adventures so that we could explore the wonders of the deep．
