GA353: Seafloor Stereo Imagery from Gippsland Basin AUV Survey

Gippsland Basin, Australia, seafloor imagery collected by an autonomous underwater vehicle (AUV) from June 19-25, 2015. The dataset includes stereo image pairs, track files, and mosaics from 12 sites, captured to assess potential impacts of seismic operations on scallops. Data was collected by Australian Marine Ecology Pty Ltd and the University of Sydney for the Gippsland Marine Environmental Monitoring project.

Use Cases

• Detect and count scallops based on high-resolution stereo seafloor imagery.
• Analyze changes in seafloor composition using georeferenced image mosaics.
• Train object detection models for marine species using calibrated underwater images.
• Assess the environmental impact of seismic surveys by comparing pre- and post-survey imagery.

Strengths

• Stereo image pairs were collected at 2 Hz with a target altitude of 2 meters, providing detailed seabed coverage.
• Cameras were calibrated in a pool immediately prior to the survey, which likely improves geometric accuracy.
• Dataset includes post-processed geotiffs, track files, and compressed mosaics for multiple analysis approaches.

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 for large-scale ML training.
