The Puerto Rico trench is the deepest part of the Atlantic Ocean, and due to its depth, it has not undergone much study in the past 25 years. However, on this recent expedition of its ocean floor, researchers were able to catch a glimpse of some rarely viewed creatures.
With ambient ocean music playing in the background, this video will not only amaze your eyes, but you will somehow get lost in the ocean yourself, even if only for two minutes. The Puerto Rico Trench reaches a maximum depth of 28,373 feet, and every foot of it provides amazing insight on the ecosystems that live beneath the ocean’s tides.
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.
Scientific studies have concluded that an earthquake occurring along this fault zone could generate a significant tsunami. The island of Puerto Rico which lies immediately to the south of the fault zone and the trench, suffered a destructive tsunami soon after the 1918 San Fermín earthquake.
