Annotated record of the detailed examination of Mn deposits from L9-84-CP (R/V S.P. Lee) expedition stations

Eighteen stations were occupied; 13 dredge hauls were collected on seamount, atoll, and island flanks and three box cores were taken from the sediment cap of an unnamed seamount in the north Marshall Islands. Every dredge haul recovered ferromanganese-oxide crusts, agreeing with the inferences of Halbach and Feller (1980) that crusts form on every hard substrate where currents or other factors preclude significant sedimentation. These samples can be viewed and studied at the U.S. Geological Survey offices in Menlo Park, California.
