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.

This dataset contains geoscientific data logged during PACLARK 3 cruise on HMAS Cook 1-12 February 1988 in Western Woodlark Basin, Papua New Guinea. These data include logged station coordinates and information for dredges, sediment grabs and seismic surveys. During four and a half days of a 3190 nautical mile deployment from Sydney to Port Moresby, HMAS Cook carried out a survey pf the Western Woodlark Basin, constituting the third PACLARK cruise. A total of 1200 nautical miles (2200km) of traverse were conducted with the stabilised narrow beam echo sounder system (SNBESS) operating almost continuously. Total magnetic field intensity was recorded during these traverses for subsequent interpretation. A single channel airgun seismic system was deployed on three traverses totalling 135 nautical miles (250km). The south flank of the pinnacle surmounting Dobu Seamount was dredged from 450m and 350m depth. En route to and from Woorlark Basin, SNBESS swaths were also obtained of the main shipping channel through the Louisade Archipelago and of the Coral Sea along tracks Sydney-Jomard Entrance-Port Moresby.

This dataset contains geoscientific data logged during PACLARK 2 (FR01/88) cruise on RV Franklin 8-28 January 1988 in Western Woodlark Basin and Goodenough Bay,Papua New Guinea. These data include logged station coordinates and information for CTD/hydrocasts, dredges, sediment cores, bathymetric surveys and camera tows. Please see the associated cruise report for details. Cruise FR 01/88 was undertaken to locate evidence of hydrothermal activity in the Western Woodlark Basin (east of Papua New Guinea) and Goodenough Bay, and to map submarine geology in an area of ocean ridge propagation into a continental margin. Survey methods included bathymetric profiling, magnetometer surveys, dredgers and gravity corers, a deep-tow camera system, and CTD casts with other associated instrumentation including a transmissometer. Numerous rock, sediment and water samples were collected for laboratory study. Related cruises are FR 02/86, FR 08/91, HMAS Cook - PACLARK III and RV Akademik Mstislav Keldysh and MIR submersibles - SUPACLARK.

This dataset contains geoscientific data logged during SOLAVENTS cruise (FR03/02) on RV Franklin 26.3-21.4.2002 in Solomon islands. These data include logged station coordinates and information for dredges, sediment grabs and cores, CTD/hydrocasts, echosounder and camera/video operations, and geological samples. SOLAVENTS-2002 was the second of two back-to-back legs during which CSIRO Exploration and Mining this year continued its study of hydrothermal mineral formation in volcanic arcs and back arcs in the South West Pacific Ocean. Commencing in Rabaul and ending in Sydney, the expedition focussed in the eastern Solomon Islands between San Cristobal and Santa Cruz. Forty-three sites were surveyed, of which 4 were completed in significant detail. We conducted 254 operations and collected 486 rock and sediment samples, totalling around 2.7 tonnes of material, 323 water samples, and made 222 on-board methane gas and 218 pH, conductivity and free-iron analyses. Forty-four biological samples were recovered serendipitously during dredging operations. The aims of SOLAVENTS cruise were as follows: - To collect new marine geoscientific and geotectonic information on a hitherto little-explored but significant island-arc region, in the eastern Solomon Islands. Among the island arc-backarc systems of the southwestern Pacific, considerable petrologic and geochemical effort has been expended in the Solomon Islands and Vanuatu. However, there is an apparent gap of fundamental knowledge, between the eastern end of the Solomon arc and the northwestern end of the Vanuatu arc in terms of known volcanism, with the exception of one known subaerial volcano (Tinakula). - To document changes over a two year period of the active submarine Kavachi volcano. - To document the state of seabed sediments and water quality in Empress Augusta Bay, 13 years after the cessation of mining on Bougainville.

This dataset contains geoscientific data logged during SHAARC cruise (FR04/00) on RV Franklin 5-24.5.2000 in Papua New Guinea and Solomon Islands. These data include logged station coordinates and information for dredges, sediment grabs and cores, CTD/hydrocasts and echosounder operations. The SHAARC research team conducted a multi-disciplinary investigation (volcanology, petrology, geochemistry and economic geology) of submarine volcanic-hydrothermal systems in island arc regions of Papua New Guinea and the Solomon Islands. The team carried out 3 primary scientific activities: (i) Volcanology/Petrology (ii) Hydrothermal Deposits/Geochemistry (iii) Marine Chemistry/Hydrothermal Fluids Although volcanism and associated hydrothermal activity on mid-ocean ridges (MOR) and some back-arc basins have been the focus of many detailed studies over the past decade, only a few submarine arcs and fore-arc regions have received much attention. FR04/00 investigations of the New Ireland-Solomon Islands convergent margin will generate a better understanding of the fundamental geological processes of submarine arc volcanism, including hydrothermal activity and the formation of economic concentrations of ore minerals. These data will be compared to and contrasted with hydrothermal activity occurring at divergent plate boundary volcanism.
