Yes, we do. There are reports on all patrol activities over the years that have been documented. The region I showed you is the northern complex. In 2012 I went to a suite of different spots in the central complex, and I didn't go to the southern complex—it's considerably damaged. The reason I work in the northern complex is that I know I can get really good information for the physiology, the information that's required.
The damage is devastating. I took colleagues a couple of weeks ago on the last couple of dives we did to see some of the places in the northern part of the northern complex where there are broken sponges.
The next questions are what the recovery potential is, what really happens as the next step, and how we can monitor this. We should be protecting these areas even if there is damage.
