LONDON, ENGLAND—Storms and flooding in Britain this winter have eroded away archaeological sites and uncovered shipwrecks. Among the damaged sites is the lost medieval port town of Dunwich, which was slowly swallowed up by the North Sea beginning with a three-day storm in 1286. The Museum of London Archaeology is therefore recruiting volunteers to help archaeologists address the emergency. “We cannot halt the erosion or destruction of some of these sites but can ensure that the information about the remains is not lost. By creating a standardized, web-based recording system and providing training and new skills, we see this as an extraordinary opportunity for people across the country to create a lasting record that will benefit us all for years to come,” Taryn Nixon, chief executive of the museum, told The Guardian.
