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

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

Use Cases

• Analyzing fish spawning behavior based on acoustic data collected during commercial fishing.
• Correlating catch data (species, length, weight) with acoustic backscatter signals.
• Mapping fishing effort and trawl locations using GPS data embedded in the acoustic files.
• Studying blue grenadier population dynamics off the Tasmanian west coast during the 2002 season.

Strengths

• Data collection was part of a formal FRDC project involving three factory freezer vessels.
• Complementary biological and trawl log data exists, though access requires contacting AFMA.

Limitations

• Cruise dates provided are a subset of the voyage; actual start/end dates are unknown.
• Column-level documentation is absent; field semantics must be inferred after download.
• No cruise track or digitised echogram data is available, only ES60 history files.
