This record is an overview entry for biological data collected on Southern Surveyor cruise SS 02/97. This cruise took place in the Torres Strait, Gulf of Carpentaria and the Arafura Sea during 12 February - 12 March 1997, under the leadership of John Salini. Biological data collected on this cruise include vertebrate and invertebrate bycatch species in prawn trawls from nine areas of the northern prawn fishery and the Torres Strait including seven subsampling prawn trawl experiments; RoxAnn and EK500 acoustic data to help discriminate bottom environments, accompanied by dredge tows and abiotic samples; saurid specimens for phylogenetic analyses and photographic specimens of commercial fishes. 24 live sea snakes were also tested for post-trawl survival, and leiognathids (ponyfish) chemically treated for otolith marking. 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.
