Composite sea surface temperature (SST) images derived from NOAA AVHRR satellite data received in Hobart, covering Tasmania and surrounding region, for comparison with, and extrapolation of, actual measurements recorded during four voyages of FRV "Southern Surveyor" over the period July 1991-April 1993 for the Tasmanian Slope Trophodynamics project. The SST images are averaged by month over a slightly longer period (January 1991-December 1993). There are also 4 higher resolution images corresponding to the times of the actual voyages, taken on 13 July 1991, 20-22 Feb 1992, 6-7 Nov 1992 and 20-26 Apr 1993. The images are composites from an original dataset of c3000 images over this period, held in the Remote Sensing Facility in Hobart.

Saxon Progress was the industry catcher vessel working in tandem with the Southern Surveyor during the July-August 1999 orange roughy research voyage at St Helens Hill and St Patricks Head. The acoustic system comprised a Sonardata Echolistener unit that digitised and recorded the output of the Furuno 28kHz commercial fisheries sounder. Related datasets: Demersal trawl data collected by the Saxon Progress during the survey; Acoustic and biological data collected by the Southern Surveyor during this same survey period - see separate Marlin entry.

This data set is the laboratory analysis of Lipids, fatty acids and sterols of numerous species of marine animals from the Tasman Sea, Pacific and Southern Ocean, collected between 1986 and 2008. Some portions of the data collection and analysis are still ongoing.

This record is an overview entry for Simrad EM1002 multibeam echosounder data collected on Southern Surveyor cruise SS 01/2000. This voyage took place off around the south-east coast of Australia including Victorian, Tasmanian and South Australian waters, in the areas of the south eastern "large marine domain" and the Great Australian Bight Marine Park, during April - May 2000, under the leadership of Rudy Kloser (legs 1 and 3) and Alan Williams (leg 2). Data-set primarliy consists of multibeam echosounder data from approx 30m to 600m water depth from the Simrad EM1002 95kHz multibeam echosounder. Key data outputs are high resolution bathymetry and acoustic seabed backscatter. 15 main sites were intensively mapped with complementary ground truth information comprising video, sediment grab, benthic sled and still photoes being taken

Acoustic biomass surveys of orange roughy at St Helens Hill and St Patricks head, off Tasmania East coast, collected during Southern Surveyour voyage SS 03/99 during July-August 1999. Acoustic system comprised a Simrad EK500 single beam vertical acoustic echosounder connected to either vessel mounted transducers or transducers housed in a deep towed body. Additional acoustic data was collected with an Echolistener digitising unit connected across the Southern Surveyor's installed 28kHz commercial fisheries sounder. The deep towed body could be operate at multi-frequcies (12, 38 and 120 kHz) to enable discrimination between orange roughy and bycatch species. In-situ measures of orange roughy target strength were made using the deep towed acoustic system. Related datasets from this survey include Bottom sled; CTD; Deep tow video transects; Midoc Midwater trawl; Echolistener data from catcher vessel FV Saxon Progress's echosounder; and Demersal trawl data from catcher vessel FV Saxon Progress.

The IMOS Bio-Acoustic Ship Of Opportunity (BA-SOOP) sub-facility is part of a major international effort that aims to determine the distribution and abundance of mid-trophic level organisms (meso-zooplanktonic and micro-nektonic) preyed by top predators (sharks, tuna) by using commercial fishing vessels (SOOP), research vessels, automated oceanic moorings, acoustic recorders, drifters and gliders. The MAAS (Mid-trophic Automatic Acoustic Sampler) project targets two levels of technology: a high level suited to large platforms such as fixed moorings, vessels or AUV and low level platforms adapted to a large number of autonomous drifters. BA-SOOP commenced on the 1st of July 2010 to collect underway acoustic data from commercial fishing and research vessels. At present, nine vessels are participating in the BA-SOOP program. Six are commercial fishing vessels that have agreed to record data during transits to and from fishing grounds. The remaining three are scientific research vessels collecting underway acoustic data during transits and science operations. Bio acoustic signals measure the distribution of mid-water prey species (micronekton) such as small fish, squid, krill and jellyfish. Micronekton form the core of the ocean food web, transferring energy from primary producers at the ocean surface to top predators such as tunas, billfish, sharks, seals and seabirds. The mass and distribution of micronekton reflects broad-scale patterns in the structure and function of the ocean, as well as the dynamics of marine ecosystems. The mapping complements established observing systems such as physical sampling of ocean currents, surveys of ocean chemistry and biology (plankton and zooplankton), and electronic tagging and tracking of large marine fish and mammals. The combined information greatly enhances the capacity of marine scientists to monitor shifts in food availability over time, assisting in the near real-time monitoring and modelling of oceanography, ecosystems, fisheries and climate change, and in understanding the behaviour of top predators. A full metadata record is also stored in each netCDF file. The document SOOP-BA NetCDF manual v1.0.doc describes the netCDF format and metadata fields that have been defined.
