The Oceanic Trench I have decided to find informationm on is the Puerto Rico Trench which is the deepest place in the Atlantic Ocean, plunging more than five miles below sea level. Lying about 75 miles north of the island of Puerto Rico, this long, narrow gash in the seafloor extends to the east for nearly 1,100 miles. The region remains poorly understood, largely because of its great depth makes it difficult to study. Even specially operated vehicles and other deep-sea research tools have not been able to reach the bottom of the trench, yet recent exploration cruises and mapping projects have begun to unravel the mystery. The Trench began to form about 70 million years ago, as the North American and Caribbean tectonic plates started to grind past each other along the Bunce Fault system
