This record is an overview entry for biological data collected on Pride of Eden cruise PoE 4/89 (originally scheduled as Soela SO 4/89; also referred to in some documentation as PoE 4/89). This cruise took place on the Australian North West Shelf during 12 September - 10 October 1989, under the leadership of Wade Whitelaw. 105 trawl stations were completed; length frequency data for 14 species of fish was collected including Saurida, Epinephelus, Lutjanus, Nemipterus, Diagramma an Lethrinus spp.; 3 hydrographic transects were carried out using a submersible data logger (SDL) to profile temperature and salinity; and numerous fish specimens were retained for further taxonomic study. Otoliths were collected from 4 of the major species (Lutjanus sebae, Lutjanus choerorynchus, Saurida undosquamis and Nemipterus furcosus). 35mm underwater photography was used successfully on 79 of the trawl stations and an underwater video camera was deployed on 17 trawls to ascertain the effects of the trawl on the benthos. Video and observations were also made of commercial trawling practices in the area as used on F.V. "Pilbura".(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff only) on-line.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 07/97. This cruise took place in the North West Shelf during 7 August - 1 September 1997, under the leadership of A. Whitelaw. Biological data collected on this cruise include numerous demersal fish and invertebrate samples; length-frequency data for 14 species of fish, and numerous otolith samples from four major species; additional fish specimens from two deeper water trawls (east of the Rowley Shoals), at 310 m and 105 m; photographs of fish and invertebrates for taxonomic studies and the "Handbook of Australian Seafood"; SDL (submersible data logger) data from 3 hydrographic transects and 35mm photography of 50% of the random trawl stations were obtained. 184 humpback whales, 24 unidentified cetaceans and about 175 dolphins were observed by Environment Australia personnel. Please note: This metadata record is a preliminary entry derived from information in the cruise plan and/or cruise report. Individual data types - which may span several cruises - will be indexed separately within this metadata system in due course.
