Seabed Imagery from Sabrina Coast Survey, East Antarctica

Six camera tow transects collected oblique still images and high-definition video of the Sabrina Coast seafloor between 480 and 1680 meters depth. Imagery was captured using a Canon 1DX and C300 camera system during the RV Investigator voyage IN2017_V01 from January to March 2017. The dataset includes associated sensor data for CTD, altitude, and pressure, published by Geoscience Australia.

Use Cases

• Classify benthic fauna and habitat types based on high-definition seafloor imagery.
• Analyze seafloor geomorphology and substrate composition using oblique still images.
• Correlate biological communities with environmental parameters based on co-located CTD sensor data.
• Study the distribution of marine life across depth gradients from 480 to 1680 meters.

Strengths

• Imagery includes both high-resolution stills (Canon 1DX) and HD video (Canon C300).
• Data is enriched with concurrent sensor readings for CTD, altitude, and pressure.
• Images were color-corrected post-collection to remove blue bias.
• Survey targeted a specific depth range (480-1680 m) on the Antarctic upper slope and shelf.

Limitations

• Metadata completeness is limited; column-level documentation is absent.
• A timing error caused an offset between image frames and sensor data, noted as being resolved.
• One tow (A008CAM02) had a USBL failure, with positions based on ship location and layback calculations.
• Row count and dataset size are unknown, which may limit suitability assessment.
