FV Ocean Dawn ES60 Acoustic Data for Tasmanian Blue Grenadier Fishing

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

Use Cases

• Analyze spawning blue grenadier distribution based on acoustic data collected during commercial fishing.
• Correlate acoustic signals with biological catch data (species, length, weight, sex, stage) provided by AFMA observers.
• Map fishing activity and trawl shot locations based on GPS data embedded in the ES60 .raw files.
• Compare acoustic data collection methods across three factory freezer vessels (FV Ocean Dawn, FV Aoraki, FV Petersen) during the 2002 season.

Strengths

• Acoustic data is complemented by biological data (species, length, weight, sex, stage) from AFMA observers.
• GPS data is embedded within the ES60 .raw files, providing spatial context.
• Data collection was part of a structured FRDC project involving three factory freezer vessels.

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 ES60 history files only, with no cruise track or digitised echogram data available.
