We have trialled a real-time video image processing system that detects motion in the hole in the ice when a seal surfaces. We then record the following two 2 minutes to document when and how seals use the hole and if they bring toothfish they’d caught to the surface for processing (They can’t eat toothfish underwater). We plan to use this system to document and monitor the sampling sites, to look for a correlation between the presence of seals and toothfish catch rates.
