Silverpit crater is a buried sub-sea structure under the North Sea off the coast of the island of Great Britain. The crater-like form, named after the Silver Pit — a nearby sea-floor valley recognized by generations of fishermen — was discovered during the routine analysis of seismic data collected during exploration for gas in the Southern North Sea Sedimentary Basin. Its meteor impact origin was first proposed and widely reported in 2002. If correct, it would be the first impact crater identified in or near Great Britain.
