The Cape Grim Baseline Air Pollution Station facility, located at the North/West tip of Tasmania (40° 41'S, 144° 41'E), is funded and managed by the Australian Bureau of Meteorology, with the scientific program being jointly supervised with CSIRO Marine and Atmospheric Research. This archive contains 1000 litre air samples contained in stainless steel flasks collected at approximately 3 monthly intervals since 1978. The archive is housed at the Aspendale laboratory of CSIRO Marine and Atmospheric Research. The Cape Grim air archive is invaluable in determining the past atmospheric composition of a wide range of gases. For some of these gases, accurate and precise analytical methods have only recently evolved (for example HFCs and PFCs). The measurements are state-of-the-art in precision and accuracy. They are used to identify trace gas trends in the Southern Hemisphere, which in turn can be used to drive climate change models and identify processes that influence changes to the atmosphere.

This record describes the datasets obtained on Courageous Cruise 018. The data were obtained from the Tasman Sea and Bass Strait in March 1977. Data were obtained from acoustic and trawl surveys of Jack mackerel (Trachurus declivis) and other demersal and pelagic fish including Trachurus mccullochi. Length and weight were determined. Levels of parasitic infestation were also noted on a routine basis from all catches. Hydrological sampling of an oceanic eddy off the NSW coast was also carried out. 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.

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.

This record describes the datasets obtained on Courageous Cruise 015. The data were obtained from waters off the New South Wales coast, Bass Strait and the east and southeast coast of Tasmania in December 1976. Data were obtained from acoustic and trawl surveys of Jack mackerel (Trachurus declivis) and other demersal and pelagic fish including Pennant lantern fish (Maurolicus muelleri), New Zealand whiptail, gemfish, southern frost fish, mirror dory, and ling. Catch rates, biomass, length, sex, gonad size and state, and target signal strength were determined.

This record describes the datasets obtained on Courageous Cruise 029. The data were obtained off the Victoria coast in Bass Strait and the NSW coast in the Tasman Sea in December 1977. Data were obtained from acoustic and trawl surveys of Jack mackerel (Trachurus declivis) and other demersal and pelagic fish including snoek (Leionura atun), yellowtail (Trachurus mccullochi) and nannygai (Centroberyx affinis). Size range were determined.

This dataset contains acoustic survey and trawl data from Courageous Cruise 002, the first in a series of surveys for Jack mackerel (Trachurus declivis) and other demersal and pelagic fish. The survey was conducted in October 1975 off the New South Wales coast between Sydney and Tathra. Species recorded in trawls included jack mackerel, nannygai, ocean perch, ling, hake, and Endeavour dogfish. Acoustic data on diurnal behaviour of jack mackerel were obtained.
