    38kHz Simrad ES60 acoustic data collected by FV Rehua during its 2008 transit from New Zealand to Australia prior to commencing commercial fishing of spawning Blue Grenadier on the west coast of Tasmania. FV Rehua is one of the Sealord factory/freezer vessels from New Zealand which fishes Blue Grenadier along the Tasmanian West Coast. Acoustic data is held by the CSIRO Marine Science Acoustic Group (Hobart). Additional data: gps embedded in ES60 .raw files, Wildlife computers MK9 temperature/depth loggers attached to headline of trawl net. During this transit Mark Lewis from CSIRO was onboard and carried out a series of midwater trawls with the MIDOC net over the course of the transit. Related data set for MIDOC sampling: Marlin ID 8355

    38kHz Simrad ES60 acoustic data collected during commercial fishing of spawning orange roughy off the Tasmanian east coast in 2004. Acoustic data is held by the CSIRO Marine Science Acoustic Group (Hobart). Additional data: gps embedded in ES60 .raw files, Wildlife computers MK9 temperature/depth loggers attached to headline of trawl net, AMFA (Australian Fisheries Mangement Authority) observer biological data (species, length, weight, sex, stage)(contact AFMA Observer section), AFMA trawl shot log - filled in by ships officers for each trawl shot, showing catch, location etc (contact AFMA Observer section).

  • The O&A Acoustic Doppler Current Profiler (ADCP) data set includes data collected during the voyages of Australia's Marine National Facility, and of various CSIRO marine research vessels. ADCP data consists of vertical current profiles binned at depth intervals of between 2 to 16 metres. The subset extracted for MARVL contains data on the continental shelf as defined by the 200 metre depth contour from the 2012 Bathymetric dataset merged (spatial union) with the Exclusive Economic Zone (EEZ) in the Australian Maritime Boundary dataset (http://www.ga.gov.au/metadata-gateway/metadata/record/gcat_63565) available from Geosciences Australia (GA). This subset of the data contains 77,693 ADCP profile records from 155 voyages and includes corrected U and V values at a centred binned depth and spans from 1995 to the present. The full data set is held in the O&A Information & Datacentre Data Warehouse, which currently holds over 387,181 ADCP profile records from more than 222 voyages collected since 1987. This data includes corrected U and V values at a centred binned depth. Individual metadata records have been created for each research voyage.
