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

12 sites were surveyed by the AUV-Phoenix from June 19-25, 2015, collecting stereo image pairs at 2 Hz. The dataset contains post-processed geotiffs, track files, and mosaics from a single camera, part of the Gippsland Marine Environmental Monitoring project to assess seismic survey impacts on scallops. The data was collected by Australian Marine Ecology Pty Ltd and the University of Sydney's Australian Centre for Field Robotics.

Use Cases

• Assessing potential impacts on scallop populations based on seafloor imagery collected before and after a seismic survey.
• Analyzing seafloor composition and structure based on high-resolution stereo images taken at a 2-meter altitude.
• Mapping benthic habitats using geotiff images and combined mosaics from 12 survey sites.
• Studying the operational challenges of AUV data collection in strong currents, as noted for Stations 14, 37, and 47.

Strengths

• Stereo image pairs were collected at 2 Hz with a target altitude of 2 m, using cameras with a resolution of 1388 x 1038 pixels.
• Camera lens and stereo orientation were calibrated in a pool immediately prior to the survey.
• Dataset includes post-processed geotiffs, track files, and compressed mosaics for each of the 12 stations.

Limitations

• Strong currents resulted in 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.
