With 'Oppenheimer' still dominating box office, expert shares findings from visit to nuclear testing site in the Pacific

The box office smash "Oppenheimer" captured imagination of a new generation of Americans who never knew a world without nuclear weapons.

University of Delaware professor Art Trembanis can provide a unique perspective on this topic as well as the history of nuclear weapon testing. Four years ago, he was part of a team that visited the Bikini Atoll in the Pacific Ocean's Marshall Islands, where the United States conducted a series of nuclear weapons tests in the 1940s and 1950s that sank warships, tanks and other vehicles as part of a simulated nuclear battlefield. He realized that if he had been in that spot during any one of those tests, he would have been engulfed in a humongous atomic mushroom cloud.

Trembanis' team was tasked with conducting an underwater mapping effort to locate and characterize the 12-ship ghost fleet that sits 180 feet deep at the bottom of Bikini Lagoon.
