Southern Surveyor Voyage SS 04/96 Biological Data Overview

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 04/96. This cruise took place in waters off northeastern and southern Tasmania during 16-30 July 1996, under the leadership of Tony Koslow and Rudy Kloser. Biological data collected on this cruise include acoustic data of orange roughy from the St. Helens spawning ground north-east of Tasmania, and in the southern orange roughy zone south of Tasmania. Acoustic targets were also investigated using demersal and mid-water trawling to assess the fish species composition. Acoustic data for bottom typing of the hills to compare with previous acoustic surveys. Acoustic and trawl data for analysis of the height and distribution of fish in the near-bottom acoustic shadow zone. Multi-frequency acoustics and depth stratified opening/closing midwater trawls to describe the community composition from the surface to 1000 m. Please note: This metadata record is a preliminary entry derived from information in the cruise plan. The biological data collected on this cruise will be updated when cruise report is available. Individual data types - which may span several cruises - will be indexed separately within this metadata system in due course.
