GA353: Seafloor AUV Imagery for Seismic Impact Assessment

June 19-25, 2015 imagery of the seafloor collected by an Iver AUV-Phoenix after a seismic survey in the Gippsland Basin. The dataset includes stereo camera images, track files, and mosaics from 12 sites, collected as part of the Gippsland Marine Environmental Monitoring project to assess 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

• Detecting and counting scallops based on high-resolution stereo image pairs.
• Analyzing seafloor composition and habitat changes based on post-processed geotiffs and mosaics.
• Mapping AUV survey tracks and image locations based on provided geospatial track files.
• Assessing image quality and coverage issues based on documented strobe failures and truncated transects.

Strengths

• Images were collected with calibrated stereo cameras at a high resolution of 1388 x 1038 pixels.
• Data includes post-processed geotiffs, track files, and compressed mosaics for 12 distinct sites.
• Documentation includes a Word file detailing folder structure, file types, and post-processing steps.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Image quality was reduced at Stations 40 and 47 due to strobe failure, and transects were truncated at Stations 14, 37, and 47 due to strong currents.
