This record describes the datasets obtained on Courageous Cruise 040. The data were obtained from the NSW coast between Sydney and Mallacoota in October 1978. Data were obtained from acoustic and trawl surveys of Jack mackerel (Trachurus declivis) and other demersal and pelagic fish. Length, sex, numbers, and weight were determined. Plankton samples from four transects were obtained. 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. See the details link under "Stored Media List" (below).

This record describes the datasets obtained on Courageous Cruise 045. The data were obtained from the Great Australian Bight in January and February 1979. Data were obtained from acoustic and trawl surveys for pelagic and demersal fish . The species studied included Chinaman leatherjacket (Navon ayraud), Green-backed stingaree and Pilchard (Sardinops sagax). Length, numbers, weight and target signal strength were determined. Plankton samples were taken at intervals during the cruise.

Field surveys were undertaken at Marmion, Rottnest Island and Jurien Bay to measure the biomass of key taxa and benthic functional groups. Surveys of fish, invertebrate and western rock lobster were completed at 32 sites across the three regions. Within each of these three key regions, sites were identified as being either reef or seagrass habitat.

This record describes the datasets obtained on Courageous Cruise 020. The data were obtained from the Tasman Sea and Bass Strait in May 1977. Data were obtained from acoustic and trawl surveys of Jack mackerel (Trachurus declivis) and other demersal and pelagic fish. Length, weight and target signal strength were determined. Data on feeding preferences were also obtained. Additional information regarding this dataset is contained in the cruise summary for this voyage. Please note: this metadata record is a preliminary entry derived from information in the cruise summary. The present location and/or continued availability of the original data, specimens etc. has not been verified at this time. Please contact the Data Centre if further details are required.

This record describes the datasets obtained on Courageous Cruise 034. The data were obtained from the Australian NW Shelf ((North West Cape to Port Hedland areas) in May 1978. Data were obtained from acoustic and trawl surveys of pelagic and demersal fish. Predominant species included goatfish (Mullidae), threadfin bream (Nemipteridae), lizard fish (Synodontidae), scad and trevally (Carangidae), pufferfish (Tetradontidae), bigeye (Priacanthidae), emperor (Lethrinidae) and to a lesser extent sea perch (Lutjanidae). Length, numbers, weight and target signal strength were determined. Zooplankton, phytoplankton and nutrient samples were also collected from three transects.
