38kHz Simrad ES60 acoustic data collected during commercial fishing of spawning blue grenadier off the Tasmanian west coast in winter of 2003. Petersen was one of three factory freezer vessels collection acoustic and biological data as part of the FRDC project gt76a. Acoustic data is held by the CSIRO Marine Science Acoustic Group (Hobart). Complementary data sets would be acoustic data collected by vessels FV Aoraki and FV Petersen as well as biological measures of fish collected by CSIRO and AFMA observers during the 2003 season.

38kHz Simrad ES60 acoustic data collected during commercial fishing of spawning blue grenadier off the Tasmanian west coast in 2002. FV Ocean Dawn was one of three factory freezer vessels collection acoustic and biological data as part of a FRDC project. Acoustic data is held by the CSIRO Marine Science Acoustic Group (Hobart). Additional data: gps embedded in ES60 .raw files, 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). Complementary data sets as per above collected by vessels FV Aoraki and FV Petersen during the 2002 season. ES60 history files only. No cruise track or digitised echogram data available. Note cruise dates here indicate the period for which we hold data. This is a subset of the voyage duration. The actual start/end dates of this voyage are not known. This information is probably in the trawl log sheets of which we have copies.
