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 processed Hydrology (HYD) data collected on Southern Surveyor voyage SS 02/94. The voyage took place in Tasmanian, Victorian and New South Wales coastal and offshore waters during 17-25 February 1994. 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 02/94. The voyage took place in Tasmanian, Victorian and New South Wales coastal and offshore waters during 17-25 February 1994. 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 dataset contains the Underway (UWY) data collected on Southern Surveyor voyage SS 02/94. The voyage took place in Tasmanian, Victorian and New South Wales coastal and offshore waters during 17-25 February 1994. 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 5 minute intervals.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 02/94. This cruise took place in Tasmanian, Victorian and New South Wales coastal and offshore waters during 17-25 February 1994, under the leadership of Barry Bruce. Biological data collected on this cruise include samples of larval fish, demersal and midwater fish, invertebrates, zooplankton and ichthyoplankton. A total of 339 stomachs from 18 species for feeding studies, 120 muscle samples (17 species) for stable isotope analysis and 315 otolith sets (15 species) and 40 vertebrae (2 species) for ageing studies. 25 fish species, including 80 kg of the oreo Neocyttus rhomboidalis from one demersal deepwater trawl. A diverse range of fish specimens for taxonomic analyses. Several benthic sediment samples for analysis of phytoplankton pigments and breakdown products. 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).
