摘要
An extensive field of mud waves occupies the Lower Continental Rise, east of Cape Hatteras, USA. Seismic profiles at Deep Sea Drilling Project Site 603 show that they have migrated ''upcurrent'' at a steadily decreasing rate, until a standing wave phase was established in the Quaternary. The growth of the waves was terminated between the early Pleistocene and Holocene by an erosional event(s). Erosion was greatest on the downcurrent sides of the waves causing an apparent upcurrent migration at the surface. It is suggested that erosion may have played a significant part in the migration of the deeper waves at Site 603.
