What is "old bering sea"

Old Bering Sea is an archaeological culture associated with a distinctive, elaborate circle and dot aesthetic style and is centered on the Bering Strait region; no site is more than 1 km from the ocean. Old Bering Sea is considered, following Henry B. Collins, the initial phase of the Northern Maritime tradition. Despite its name, several OBS sites lie on the Chukchi Sea. The temporal range of the culture is from 400 BCE to possibly as late as AD 1300.
