CTD Camera Images from the 2021 TEMPO Antarctic Voyage

Deep-sea camera images collected to investigate krill activity near the seafloor in the East Antarctic Southern Ocean. The dataset contains raw seafloor images and metadata from the RV Investigator voyage IN2021_V01, which took place from 29 January to 24 March 2021. Images were captured using a Canon HFG10 camera mounted to a CTD rosette frame during full-depth deployments.

Use Cases

• Analyze krill presence and behavior in abyssal environments based on deep-sea imagery.
• Study seafloor composition and benthic habitats based on high-quality still images.
• Correlate biological observations with oceanographic data from concurrent CTD deployments.
• Investigate the effects of ship and cable motion on underwater imaging based on the described capture process.

Strengths

• Images collected during every full-depth CTD deployment throughout the voyage.
• Highest-quality image(s) selected for each CTD deployment are included.
• Specific camera model (Canon HFG10) and detailed capture procedure are documented.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to the single 2021 voyage.
