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

Six camera tow transects collected seafloor imagery and sensor data on the RV Investigator from January to March 2017. The survey targeted the upper slope and outer continental shelf of the Sabrina Coast in East Antarctica at depths between 480 and 1680 meters. The dataset includes colour-corrected still images, high-definition video, and associated metadata from sensors like CTD, altimeter, and pressure sensors.

Use Cases

• Classifying benthic organisms based on colour-corrected seafloor imagery.
• Analyzing seafloor topography and substrate based on altimeter and pressure sensor data.
• Studying oceanographic conditions (temperature, salinity) from CTD sensor data linked to image locations.
• Training computer vision models for automated detection of marine fauna in oblique downward-facing images.

Strengths

• Includes six distinct camera tow transects with detailed sensor metadata.
• Imagery was colour corrected to remove blue bias, improving visual analysis.
• Sensor suite includes CTD, altimeter, pressure, and USBL for locational data.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• A timing error created an offset between sensor data (CTD, altimeter, pressure) and the images.
• Row count is unknown, which may limit suitability assessment.
