We have been pioneering methods for surveying both coral and temperate reefs using diver-held and AUV systems. Our latest innovation allows us to reliably survey 100m2 areas with our diver operated system. A pole is installed in the middle of the survey area with a rope wound around a 15cm diameter tube. As the diver swims around the pole, the line is paid out allowing full coverage of the survey area to be achieved. This method was adopted during recent surveys of reefs at Lizard Island affected by Cyclone Ita.
