IN2017_V01: Seabed Imagery and Sensor Data from Sabrina Coast, East Antarctica

January to March 2017 survey collected six camera tow transects on the RV Investigator. The dataset includes oblique downward-facing still images and high-definition video from the Sabrina Coast seafloor between 480 and 1680 meters depth, along with CTD, altimeter, and pressure sensor metadata. It is published with the permission of Geoscience Australia and the Marine National Facility.

Use Cases

• Classify benthic species and habitats based on color-corrected seabed still images.
• Analyze seafloor topography and features using video footage and altimeter data.
• Model oceanographic conditions (temperature, salinity) using synchronized CTD sensor readings.
• Assess the impact of survey methodology (e.g., ship speed, tow path) on image quality and data alignment.

Strengths

• Imagery includes color correction to remove blue bias, improving visual analysis.
• Metadata includes precise location, depth, altitude, and CTD measurements for environmental context.
• Data collection used specialized equipment including a Deep Tow Camera system with scale lasers and multiple sensors.

Limitations

• A timing error creates an offset between image files and CTD/altimeter/pressure sensor data.
• For one tow (A008CAM02), location data is based on ship's position and layback calculations due to USBL failure.
• Column-level documentation is absent; field semantics must be inferred after download.
