The Percent Live Coral Cover attribute describes the hardbottom area of the seafloor that is colonized by live hard and soft corals, as interpreted from a video camera looking straight down at the sea floor from 1-2 meters height. To get an estimate of total percent coral cover on the scale of the polygon level (i.e., >100m²) in areas with patchy hardbottom cover, the percent coral cover needs to be combined with the percent hardbottom modifier. It is important to note that the percent live coral cover class is different from percent biological cover, which denotes the patchiness of biological cover at the scale of the polygon including both hard and soft bottom. |
