| Aggregate Reef | High relief, lacking sand channels of spur and groove. |
| Aggregated Patch Reef | Clustered patch reefs that individually are too small (less than the minimum mapping unit) or are too close together to map separately. |
| Mud | Fine sediment, often associated with river discharge and (or) build-up of organic material in areas sheltered from high-energy waves and currents. |
| Pavement | Flat, low-relief, solid carbonate or volcanic rock. |
| Reef Rubble | Dead, unstable coral rubble. |
| Rock/Boulder (Volcanic and Carbonate) | Solid carbonate blocks and/or boulders or volcanic rock. |
| Sand | Coarse sediment typically found in areas exposed to currents or wave energy. |
| Scattered Coral/Rock | Substrate with scattered rocks or small, isolated coral heads that are too small to be delineated individually (smaller than an individual patch reef) |

|---|---|
| Bank/Shelf | The edge of the bank/shelf where depth increases rapidly into deep, oceanic water. |
| Channel | Naturally occurring channels that often cut across several other zones. |
| Fore Reef | Area from the seaward edge of the reef crest that slopes into deeper water to the landward edge of the bank/shelf platform. |
| Reef Crest | The flattened, emergent (especially during low tides) or nearly emergent segment of a reef. This zone lies between the back reef and fore reef zones. |
| Reef Flat | Shallow (semi-exposed) area between the shoreline intertidal zone and the reef crest of a fringing reef. This zone is protected from the high-energy waves commonly experienced on the shelf and reef crest. |
| Vertical Wall | Area with near-vertical slope. |
