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.

Both the CSIRO "Thunderbird" and BSI Radiometers were deployed on the SS 03/96 cruise in the oceanic and shelf waters off south eastern New South Wales and eastern Tasmania.Deployments took place around midday irrespective of position.

This dataset contains the processed Hydrology (HYD) data collected on Southern Surveyor voyage SS 03/96. The voyage took place in Oceanic and shelf waters off eastern New South Wales during May 1996. This dataset has 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 and/or the data processing report (as available). Southern Surveyor on-voyage hydrology data are typically obtained from water samples collected in Niskin bottles at various depths during each CTD cast. Parameters measured normally comprise temperature, salinity, dissolved oxygen, phosphate, nitrate, silicate, and nitrite.

This dataset contains the processed Conductivity-Temperature-Depth (CTD) data collected on Southern Surveyor voyage SS 03/96. The voyage took place in Oceanic and shelf waters off eastern New South Wales during may 1996. This dataset has 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 and/or the data processing report (as available).

This record contains data collected at 24 stations on the Southern Surveyor cruise SS 03/96. Water samples were collected off the east coast of NSW near Eden and along a transect from Hobart to Eden to determine the bio-optical characteristics of water masses in this region. Parameters measured are the concentration of chlorophyll and carotenoid pigments and the absorption coefficient for dissolved (CDOM) particulate (a/p) and detrital or non-algal (a/d) components of the water column. In addition to the station samples 124 water samples were collected from the outflow of the underway fluorometer and analysed for the concentration of chlorophyll and carotenoid pigments only. A BI(Biospherical Instruments) six channel radiometer was also deployed at the stations during this voyage.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 03/96. This cruise took place in oceanic and shelf waters off south eastern NSW and the east coast of Tasmania during 13-27 May 1996, under the leadership of Jock Young. Biological data collected on this cruise include 75 stomachs of yellowfin tuna and one northern bluefin tuna, fish, larval fish, phyllosoma and benthic samples. Zooplankton (including on board photography) micronekton and phytoplankton samples. Acoustic data for species identification and biomass studies. Multi-beam sonar data of pelagic fish distribution and school behaviour. 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 study examined the larval biology and ecology of the southern rock lobster (Jasus edwardsii) based on approximately 3000 archived plankton and mid-water trawl samples held, principally, by CSIRO, Tasmanian Aquaculture and Fisheries Institute, and the Marine and Freshwater Research Institute, Victoria. Additional samples were provided by the National Institute of Water and Atmosphere, New Zealand; some samples were opportunistically collected during the project to fill in areas where there was a lack of archived samples. The combined sample set covered the major geographic range of the fishery in Australia (132E/32S - 155E/46S). Details of larval growth, duration and distribution were combined with concurrently collected hydrographic data and satellite based observations to examine possible larval transport mechanisms, connectivity between management zones and physical factors that may influence the supply of larvae on a regional basis. The dataset is primarily in Excel format with a summary of the results presented in a final report to FRDC (project number 96/107).
