PACLARK 3 Geoscientific Data 1988

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.
