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

Stereo camera images of the seafloor collected by an AUV-Phoenix autonomous underwater vehicle from 19-25 June 2015. The dataset is part of the Gippsland Marine Environmental Monitoring project, developed by Geoscience Australia and partners to assess potential impacts of seismic operations on marine organisms. It includes post-processed geotiffs, track files, and image mosaics from 12 survey stations.

Use Cases

• Detecting and counting scallop populations based on high-resolution seafloor imagery.
• Assessing changes in seafloor morphology before and after seismic surveys using geotiff images.
• Training computer vision models for marine species identification using stereo image pairs.
• Analyzing AUV navigation and image coverage patterns using provided track files.

Strengths

• Stereo image pairs collected at 2 Hz with a calibrated camera system, suggesting precise spatial measurements.
• Images have a resolution of 1388 x 1038 pixels from high-sensitivity CCD cameras.
• Data collection targeted a consistent 2 m altitude above the seabed, likely providing uniform scale.

Limitations

• Strong currents truncated transects at Stations 14, 37, and 47, and strobe failure reduced image quality at Stations 40 and 47.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
