<strong>Status</strong> <strong>of</strong> <strong>Coral</strong> <strong>Reefs</strong> in <strong>the</strong> Eastern Caribbean<br />

<strong>the</strong>n <strong>the</strong>re is a gently sloping sandy shelf and extensive patch reefs in depths <strong>of</strong> 6-15m. A<br />

bank reef runs parallel to, and approximately 1000m from <strong>the</strong> shore, and is continuous with<br />

<strong>the</strong> west coast bank reef. The south-east coast is fully exposed to <strong>the</strong> Atlantic swells with<br />

heavy surf. There are no actively growing fringing reefs, however <strong>the</strong>re is a flat, shallow<br />

bank reef, 400-800m from shore running roughly parallel to it. The east coast is fully<br />

exposed to Atlantic swells and consists <strong>of</strong> limestone pavements in <strong>the</strong> sou<strong>the</strong>rn areas as a<br />

gently sloping featureless ramp from <strong>the</strong> beach <strong>of</strong>f <strong>the</strong> Scotland District out to 40-60m.<br />

Fur<strong>the</strong>r north (<strong>of</strong>f Pico Tenerife), <strong>the</strong> bottom type changes abruptly as <strong>the</strong>re is a submarine<br />

canyon. North <strong>of</strong> <strong>the</strong> canyon, <strong>the</strong> shelf is terraced and carbonate rich, while to <strong>the</strong> south it<br />

is more terrestrial and <strong>the</strong> slope is more gentle. The north coast has a rock terrace which<br />

extends seaward from <strong>the</strong> base <strong>of</strong> 100m cliffs out to 40-60m, ending in a ridge parallel to<br />

shore with ano<strong>the</strong>r terrace and isolated ridges and mounds fur<strong>the</strong>r seaward. The north<br />

west coast is particularly well sheltered and supports <strong>the</strong> most extensive and diverse hard<br />

coral reefs on <strong>the</strong> island.<br />
