This record describes the datasets obtained on Courageous Cruise 047. The data were obtained from the Great Australian Bight in March and April 1979. Data were obtained from acoustic and trawl surveys of pelagic and demersal fish. New species distributions were obtained for fish including the footballer sweep (Neatypus obliquus), stargazer (Pleuroscopus psuedodorsalis), and various myctophids. Four species from trolling included Bonito (Sarda orientalis), Southern bluefin tuna (Thunnus maccoyi), Albacore (Thunnus alalunga) and Skipjack tuna (Katsuwonus pelamis). Length, numbers, weight and target signal strength were determined. Selected species of sponges were kept for taxonomic studies. Plankton observations were made in connection with studies of the distribution of pilchard (Sardinops neopilchardus). Additional information regarding this dataset is contained in the cruise summary for this voyage.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.
