Annotated record of the detailed examination of Mn deposits from the 1968, R/V Mahi expeditions in the Pacific Ocean

This report represents the first in a projected series reporting core descriptions and their physical properties, to be made available through routine core handling procedures instituted at the Hawaii Institute of Geophysics in 1968 to keep pace with the capability to take long (120-foot) piston cores from the University of Hawaii's R/V MAHI. The data reported herein cover sediment cores collected during 1967, 1968, and 1969 in the region of the Solomon Islands and the Darvir. Rise, and along the central portion of the Murray Fracture Zone.
