BOI Dropped Underwater Video (DUV) data in the Bay of Islands - RV Hawere

The Dropped Underwater Video (DUV) data provide supplementary information for the characterisation of the demersal fish communities within the Bay of Islands, especially in shallow waters. This system was deployed at 76 sites by RV Hawere. Each deployment was about 30 minutes long and the camera was flown at 2–3 m above the seabed, depending on the visibility.

Supplemental Information
Fish below 5cm will not be represented in the data because they were too small to be identified. Not all fish that were identified were measured due to their orientation to the camera and some of those fish that were not identified were able to be measured.
