Discover how three extreme environments affect all of us at World of Discovery: Exploring Our Global Environment, a three-part series at the Delaware Museum of Natural History featuring scientists from the University of Delaware’s College of Earth, Ocean and Environment sharing their research. Topics include the inhospitable climate of Antarctica, how volcanoes are a window into the history of our planet, and the effects of nuclear weapons under the sea.

Bombs at Bikini—Exploring the Underwater Impacts of Nuclear Weapons Testing, Thursday, December 5 | 7-8:30 p.m.

 

From 1946 to 1958, the United States conducted dozens of nuclear tests on Bikini Atoll in the Marshall Islands. The legacy of this testing has been considerable, historically, culturally and environmentally. Displaced residents have been unable to return due to lingering radionuclides, and the site was named a World Heritage Site by the United Nations Educational, Scientific and Cultural Organization (UNESCO) due to the impact the escalating power of nuclear testing had on the world.

University of Delaware oceanography professor Art Trembanis used a variety of technologies from the Robotic Discovery Laboratories of the College of Earth, Ocean and Environment to map the seafloor surrounding Bikini Atoll earlier this year. His research provided detailed information on the many ships intentionally sunk in the testing and revealed the extent of the undersea crater left by one of the explosions. His talk will share some of what his team learned and how they did their work.

Art Trembanis is an associate professor in the School of Marine Science and Policy at the University of Delaware and directs the Coastal Sediments Hydrodynamics & Engineering Lab (CSHEL), which seeks to understand the morphodynamic processes of coastal systems. His research focuses on both the seabed and the shoreline and how they change, and the use and development of autonomous underwater vehicles (AUVs) for oceanographic observations. He earned his Ph.D. from the Virginia Institute of Marine Studies of the College of William and Mary.
