Courageous Cruise 030 Biological Data overview, 1978

This record describes the datasets obtained on Courageous Cruise 030. The data were obtained from the east Tasmanian continental shelf and waters of the coast of New South Wales in the Tasman Sea in January 1978. Data were obtained from acoustic and trawl surveys of Jack mackerel (Trachurus declivis) and other demersal and pelagic fish. Size range and catch rates were determined. The second part of the cruise involved midwater trawling for fish species inside and outside an eddy located off the NSW coast. 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.
