GA353: AUV Seafloor Imagery from Gippsland Basin Post-Seismic Survey

Gippsland Basin seafloor images collected by an AUV-Phoenix vehicle from June 19-25, 2015. The dataset contains stereo camera images, track files, and mosaics from 12 sites, intended to analyze potential impacts of a seismic survey on scallops. Data was collected by Australian Marine Ecology and the University of Sydney for the Gippsland Marine Environmental Monitoring project.

Use Cases

• Assess changes in scallop populations based on high-resolution seafloor imagery.
• Map seafloor habitats using post-processed geotiff images and mosaics.
• Analyze AUV navigation and image quality issues based on documented strobe failures and strong currents.

Strengths

• Stereo image pairs collected at 2 Hz with a target altitude of 2 meters above the seabed.
• Cameras were calibrated in a pool immediately prior to the survey.
• Includes post-processed geotiffs, track files, and compressed mosaics for each station.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Strong currents and strobe failures at specific stations resulted in truncated transects and reduced image quality.
