This dataset contains geoscientific data logged during PACMANUS 1 / PACLARK 5 cruise (FR08/91) on RV Franklin 24 September to 14 October 1991 in Western Woodlark Basin and Eastern Manus Basin, Papua New Guinea. These data include logged station coordinates and information for sediment grabs and cores, CTD/hydrocast operations and samples, camera/video tows and footage, bathymetric surveys and geological and fauna samples. Cruise FR08/91 was an outstanding success and achieved all major objectives, significantly expanding geological knowledge of two key areas of sea floor comparable with the environments of ancient "volcanogenic massive sulfide" (VMS) orebodies. Highlights were the discovery of a new active hydrothermal field ("PACMANUS") forming sulfide deposits associated with dacite in the eastern Manus Basin, and the acquisition of cored sections through low temperature Fe-Mn-Si oxide deposits on Franklin Seamount, a basaltic andesite volcano in the western Woodark Basin. Operations comprised a total of 30 rock dredges, 18 gravity cores, 13 camera-video tows, and 14 CTD-hydrocasts was conducted in the two areas in addition to 12 kHz echosounding. Total distance covered was 2479 nautical miles, of which 360 miles was between stations in the 2 areas of operations and the remainder was in transit.
