Don Walsh is an explorer and oceanography professor. As a member of our Advisory Board, Dr. Walsh connects EYOS to the latest developments in modern exploration and science.

He may be best known as the pilot of the bathyscaphe Trieste, which in 1960 dived to the Mariana Trench (35,840ft).


Don was educated at the US Naval Academy in Annapolis (BS in engineering), Texas A&M University (MS and PhD in oceanography), and San Diego State University (MA in political science). He also spent 14 months as Resident Fellow at the Woodrow Wilson International Center for Scholars at the Smithsonian.


In 1975, he retired as a Captain to accept a professorship of ocean engineering at the University of Southern California (USC). There he became founding Director of the Institute for Marine and Coastal Studies (IMCS) with rank of dean. Dr. Walsh is author of over 200 ocean-related publications from brochures to book chapters. He has presented over 1,700 lectures, television and radio programs in 64 countries.

Expedition Experience

For the past four decades, Dr. Walsh has also worked in both Arctic and Antarctic regions, including the North Pole (five trips) and South Pole. To date, he has participated in over 50 polar expeditions. The “Walsh Spur” (ridge) near Cape Hallett is named for him in recognition of his contributions to the US Antarctic Program.


In 2000, Dr Walsh was awarded The National Geographic Society’s highest award, the Hubbard Medal.

In 2001, Dr. Walsh was elected to the National Academy of Engineering, awarded the Explorers Medal by The Explorers Club (and previously he had received their Lowell Thomas Medal) and, cited as one of the great explorers in the Life Magazine book, “The Greatest Adventures of All Time”.
