<P> The Puerto Rico Trench is located on the boundary between the Caribbean Sea and the Atlantic Ocean . The oceanic trench is associated with a complex transition between the Lesser Antilles subduction zone to the south and the major transform fault zone or plate boundary , which extends west between Cuba and Hispaniola through the Cayman Trench to the coast of Central America . The trench is 800 kilometres ( 497 mi ) long and has a maximum depth of 8,648 metres ( 28,373 ft ) or 5.373 miles at Milwaukee Deep , which is the deepest point in the Atlantic Ocean and the deepest point not in the Pacific Ocean . </P>
