This record is an overview entry for biological data collected on Southern Surveyor cruise SS 03/93. This cruise took place in waters off southern Tasmania during 7-22 April 1993, under the leadership of Brian Griffiths. Biological data collected on this cruise include samples of demersal fish, midwater nekton and zooplankton to determine the vertical distribution and diurnal movements of these three groups, and samples for trophic analyses. Acoustic data for biomass estimates. Oceanographic samples to determine the vertical and horizontal distribution of biological properties of the water column. 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.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 03/92. This cruise took place in waters off the northeast and west coasts of Tasmania during 15 July - 13 August 1992, under the leadership of Tony Koslow. Biological data collected on this cruise include samples of orange roughy and blue grenadier including other fish, acoustic data and target strength measurements of the fish. Orange roughy eggs were sampled for buoyancy experiments and to determine the vertical distribution of eggs from 0-900 m depth. 9 samples of flesh, liver, gonads, and otoliths from 36 cm orange roughy at reproductive Stage IV were obtained to examine the relationship of body condition to fecundity. Blue grenadier eggs were also sampled to determine the vertical distribution of eggs from 0-600 m depth and for incubation experiments. CTD profiles were carried out during the cruise to determine sound velocity and absorption profiles.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 02/91. This cruise took place in waters off the south and east coasts of Tasmania, around Maatsuyker Island, Flinders Island, St Helens Hill and approximately 40 miles east of Maria Island during 26 June - 16 July 1991, under the leadership of Tony Koslow. Biological data collected on this cruise include samples of fish and zooplankton from demersal, midwater and plankton tows. Stomach samples for gut content analysis. Acoustic data and target strength measurements of orange roughy. Orange roughy eggs including other fish eggs for vertical distribution examination, and for incubation and buoyancy experiments. 29 species of seabird were observed and recorded during the cruise: 5 albatross, 15 petrels, 1 storm-petrel, 1 diving-petrel, 1 gannet, 3 gulls, 2 terns, and 1 skua species. Whale observations were also recorded. CTD/productivity transects were also carried out east of Flinders Island, Pedra Branca and in the Japanese longline fishery area (off the east coast of Tasmania).
