IN2017_V01: Seabed Imagery from the Sabrina Coast, East Antarctica

East Antarctic seafloor imagery from six camera tow transects conducted between January and March 2017 on the RV Investigator. The survey targeted the upper slope and outer continental shelf of the Sabrina Coast at depths between 480 and 1680 meters. Imagery was collected using a Deep Tow Camera system capturing still images and HD video, accompanied by sensor data for CTD, altitude, and pressure.

Use Cases

• Classifying benthic fauna and habitat types based on high-definition still and video imagery.
• Analyzing seafloor geomorphology and substrate composition from oblique camera transects.
• Correlating biological observations with environmental parameters like temperature, salinity, and depth.
• Training computer vision models for automated detection of marine organisms in seabed imagery.

Strengths

• Imagery includes both high-resolution still images from a Canon 1DX and HD video from a Canon C300.
• Sensor suite provides concurrent CTD, altimeter, pressure, and positional data for environmental context.
• Six distinct camera tow transects provide spatial coverage of the Sabrina Coast upper slope.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• A timing error caused an offset between image frames and sensor data, which the data provider notes is being resolved.
