The 30-ft long core samples drilled and brought up from the ocean bed in numerous locations, provided data on seafloor spreading, expanding knowledge of plate tectonics. The 120m long vessel was chartered by American science institutions: the National Science Foundation and University of California Scripps Institute of Oceanography.
