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. {"type": "Polygon", "coordinates": [[[141.0, -12.0], [162.0, -12.0], [162.0, -2.0], [141.0, -2.0], [141.0, -12.0]]]} 141.0 162.0 -12.0 -2.0 Graphics Link documentDigital supaclark_cruise_report_maps.pdf HTML Data Link documentDigital supaclark.zip (includes data files and pdf docs) HTML Documentation Link documentDigital supaclark_operations_list.pdf HTML
