High Profile reef

Three main rocky reef classes have been identified in the SeaMap Tasmania habitat classifications. These classes include high profile reef, medium profile reef and low profile reef. An additional category defined as patchy reef is baed on the spatial  structuring that results in distinct patches of reef between areas of unconsolidated substrate.

High profile reef is used to characterise the consolidated seabed when the vertical profile changes by up to 4 m across a linear distance of 10 m. It is usually coincident with steep underwater cliffs, large boulder fields or areas of very high rugosity.
