SUPACLARK Geoscientific Data 1990

This dataset contains geoscientific data logged during SUPACLARK cruise on RV Akademik Mstislav Keldysh 8-29 April 1990 in Western Woodlark Basin, Papua New Guinea. These data include logged station coordinates and information for sediment grabs and cores, CTD/hydrocast operations and submersible operations. SUPACLARK was a joint marine geological/geophysical investigation of the Western Woodlark Basin by the USSR Academy of Sciences, CSIRO Australia and the University of Toronto, Canada aimed at furthering knowledge obraind on PACLARK I (1986), II and III (1988) on seafloor hydrothermal activity associated with initial rifting of continental crust where the Woodlark seafloor spreading axis is propagating into the Austral-Papuan continental margin. A program of mamned dives with the USSR's MIR submersibles was integreated with a surface program of narrow beam echo sounding, CTD/hydrocast rosettes and sediment grabs and cores plus some miscallaneous operations.
