Glomar Challenger has been engaged in its unique assignment of investigating the character of deep-ocean-floor sediments since August, 1968 and at year end was well into the third of four Atlantic Ocean segments. The very comprehensive documentation of this effort includes the film that is presented with this paper, which was taken during the sea trials and first leg of the voyage.

A geologic summary of the status and goals of the program and some of the findings developed during the Challenger's initial efforts is presented by courtesy of Scripps Institution of Oceanography, operators for the program. Both the technical and academic results of the coring program have been very gratifying to date.
