OCD200201: 38kHz Acoustic Data from Blue Grenadier Fishing, Tasmania 2002

38kHz Simrad ES60 acoustic data collected during commercial fishing for spawning blue grenadier off the Tasmanian west coast in 2002. The data was gathered by the FV Ocean Dawn as part of an FRDC project, with complementary data from two other vessels. Acoustic data is held by the CSIRO Marine Science Acoustic Group in Hobart.

Use Cases

• Analyze fish biomass and distribution based on 38kHz acoustic backscatter data.
• Correlate catch data with acoustic signatures using linked biological data on species, length, and weight.
• Map fishing activity and trawl locations using embedded GPS data mentioned in the description.
• Study spawning behavior of blue grenadier using time-series acoustic data from the 2002 season.

Strengths

• Data is part of a coordinated FRDC project involving three factory freezer vessels.
• Includes complementary biological and trawl log data from the Australian Fisheries Management Authority.
• Acoustic data is managed by the CSIRO Marine Science Acoustic Group, a known research institution.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset contains only ES60 history files; no cruise track or digitised echogram data is available.
