Scientific Purpose/Goals: The main focus of RC2901 was a geophysical study of the interaction between the Chilean ridge and trench. The inner trench slope accretionary processes and the extent of the continental crust were of particular interest. Multichannel seismic surveys were conducted in four areas: 35 -40 S were surveyed as a subcontract for the Chilean oil company, ENAP; three areas at 44 30S, 46 S, and 48 S were surveyed as possible ODP drilling sites. Magnetics, gravity and Sea Beam were run at all times during these surveys. An intensive seven day Sea Beam survey was conducted from 45 30S to 47 S in the area where the Chile trench is actively subducting a segment of the Chilean ridge. Single channel seismic, magnetics and gravity data were also collected during the survey.
