This data set contains Simrad EK500 single beam echosounder data at 38 and 120 kHz and Simrad EA500 single beam echosounder data at 12 kHz from the Southern Surveyor. The EK500 data is primarily for water column characterisation (fish stocks, microplankton distribution) and on occasions for seabed classification (particularly prior to the EM300 swath mapper being installed), while the EA500 data is primarily for bathymetric readings.

This dataset contains the Underway (UWY) data collected on Southern Surveyor voyage SS 07/97. This cruise took place in the North West Shelf during 7 August - 1 September 1997, under the leadership of A. Whitelaw. This dataset has NOT been processed and is archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the cruise report for this voyage. The standard Underway (=continuously recorded) dataset from a research voyage includes Navigation (NAV), Sounder, Thermosalinograph (TSG) and Meteorological (MET) data. NAV data includes GPS (Global Positioning System) measurements of latitude, longitude, ship's direction and speed. MET data includes atmospheric temperature, humidity and pressure, wind speed and direction, and incident radiation intensity. Data are recorded at or averaged over 1 minute intervals.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 07/97. This cruise took place in the North West Shelf during 7 August - 1 September 1997, under the leadership of A. Whitelaw. Biological data collected on this cruise include numerous demersal fish and invertebrate samples; length-frequency data for 14 species of fish, and numerous otolith samples from four major species; additional fish specimens from two deeper water trawls (east of the Rowley Shoals), at 310 m and 105 m; photographs of fish and invertebrates for taxonomic studies and the "Handbook of Australian Seafood"; SDL (submersible data logger) data from 3 hydrographic transects and 35mm photography of 50% of the random trawl stations were obtained. 184 humpback whales, 24 unidentified cetaceans and about 175 dolphins were observed by Environment Australia personnel. 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.
