GA353: Seafloor AUV Imagery from Gippsland Basin After Seismic Survey

Stereo image pairs of the seafloor were collected at 2 Hz from an autonomous underwater vehicle (AUV) at a target altitude of 2 meters. This dataset contains post-processed geotiffs, track files, and mosaics from 12 sites surveyed in June 2015 to analyze potential impacts of seismic operations on scallops. The data was collected by Australian Marine Ecology and the University of Sydney for the Gippsland Marine Environmental Monitoring project.

Use Cases

• Assessing changes in scallop populations based on pre- and post-seismic survey imagery mentioned in the description
• Analyzing seafloor habitat composition using high-resolution stereo camera images
• Mapping benthic features and creating mosaics from the combined geotiff files
• Studying the effects of strong currents on AUV survey operations and data quality

Strengths

• High-resolution imagery from calibrated stereo cameras with a resolution of 1388 x 1038 pixels
• Includes post-processed geotiffs, track files, and compressed mosaics for each station
• Data collection followed a specific protocol with target altitude of 2m and speed of 1 m/s

Limitations

• Strong currents resulted in truncated transects at Stations 14, 37, and 47
• Strobe failure on Stations 40 and 47 resulted in reduced image quality
• Column-level documentation is absent; field semantics must be inferred after download
