OCD200201: 2002 Blue Grenadier Spawning Acoustic Data from Tasmanian West Coast

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 factory freezer vessel 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

• Analyzing fish school density and distribution based on 38kHz acoustic backscatter.
• Correlating acoustic data with biological samples (species, length, weight, sex, stage) from AFMA observers.
• Mapping fishing effort and trawl locations using GPS data embedded in the .raw files.
• Studying commercial fishing patterns during the 2002 spawning season off Tasmania.

Strengths

• Data collected as part of a formal FRDC (Fisheries Research and Development Corporation) project.
• Complementary biological and trawl log data available from the Australian Fisheries Management Authority.
• Acoustic data from three factory freezer vessels (FV Ocean Dawn, FV Aoraki, FV Petersen) during the 2002 season.

Limitations

• Data consists of ES60 history files only; no cruise track or digitized echogram data is available.
• The provided cruise dates represent only a subset of the voyage duration; actual start/end dates are not known.
• Column-level documentation is absent; field semantics must be inferred after download.
