Barbados Ridge
submarine feature, Caribbean Sea
Barbados Ridge, submarine ridge of the Caribbean Sea rising from the southern end of the axis of the Puerto Rico Trench. The Barbados Ridge is paralleled on either side by a shallow trough. Negative gravity anomalies (observed gravity values less than theoretically calculated values because of a mass deficiency at depth in the Earth) associated with the Puerto Rico Trench extend over the Barbados Ridge, and thus structural continuity between these two features is established.
