Annotated record of the detailed examination of Mn deposits observed in the Pacific Ocean by the USC&GS Ship Explorer in 2 February-27 April, 1960

This report contains the field data obtained during the February to April 1960 oceanographic expedition of the USC&GS ship Explorer, together with such results from the analyses of these data as are completed to date. As additional studies are completed, the results will be published by the U.S. Coast and Geodetic Survey or by the other Government agencies, private oceanographic institutions, or individual scientists who are primarily concerned. The USC&GSS Explorer is a 1,900-ton, 220-foot Ocean Survey Ship (OSS 28). During the winter of 1960, the ship was scheduled for a routine transfer from her original home port of Seattle, Wash., to be based in the future out of Norfolk, Va. With the current accelerated demand for oceanographic information, it was felt that this transfer offered a unique opportunity to obtain useful oceanographic information along the route from Seattle to Norfolk.
