Bridget Buxton, associate professor of history at the University of Rhode Island, will present a lecture on “Underwater Archaeology: The New Holy Grails” at 7 p.m., Thursday, Nov. 10, in 120 Smith Hall on the University of Delaware campus in Newark.

Buxton, an underwater archaeologist who has led expeditions across the Mediterranean, will discuss new discoveries and future challenges in the field.

Her own discoveries include a medieval shipwreck filled with more than 3,000 gold coins, ancient Roman bronzes and American planes lost during World War II.

She collaborates with European and American colleagues to apply new robotic technologies in underwater archaeology and is an advisor of Oceangate Foundation.

The lecture, which is free and open to the public, is sponsored by Ancient Greek and Roman Studies in UD’s Department of Languages, Literatures and Cultures.
