Milwaukee Deep, also known as The Milwaukee Depth, (Lua error in package.lua at line 80: module 'strict' not found.) is the deepest part of the Atlantic Ocean and is part of the Puerto Rico Trench.[1] It has a maximum depth of at least 27,493 feet (8,380 m). It is just 76.0 miles (122.3 km) north of the coast of Puerto Rico at Punto Palmas Altas in Manatí.[2][3]

This ocean floor feature is named for the USS Milwaukee (CL-5), a U.S. Navy Omaha class cruiser, which discovered the Milwaukee Deep on February 14, 1939 with a reading of 28,680 feet (8,740 m).[4][5]

On August 19, 1952, the U.S. Fish and Wildlife vessel Theodore N. Gill obtained a reading of 28,560 feet (8,710 m) at (Lua error in package.lua at line 80: module 'strict' not found.), virtually identical with the Milwaukee's reading.

The existence of deep water to the Atlantic Ocean side of the Caribbean has been known for more than a century. One of the area's earliest soundings was obtained June 12, 1852 by Lt. S. P. Lee, U.S. Navy brig Dolphin, with a reading of 22,950 feet (7,000 m) at (Lua error in package.lua at line 80: module 'strict' not found.).[6]
