Video data collection

The Coral Reef/Hardbottom Monitoring Project collects video data. Shown here, a scientist swims a video camera along a 20m transect line (faint yellow line). The camera is held at a constant height of 40cm by looking at a pair of laser dots. When the dots overlap, the camera is exactly 40 cm above the bottom. We swim very slowly during this video data collection, taking about 5 minutes to swim a 20m long transect. Coral staff do this for about 10 kilometers (6 miles) each summer. The Coral Reef/Hardbottom Monitoring Project video transects combined cover about three quarters of a square kilometer of reef habitat.

FWC Facts:
Just like fish, blue crabs use gills to breathe. But unlike fish, blue crabs can survive out of water for over 24 hours, as long as their gills are kept moist.
