The Puerto Rico Trench is located on the boundary between the North Atlantic Ocean and Caribbean Sea, parallel to and north of Puerto Rico, where the oceanic trench reaches the deepest points in the Atlantic Ocean. The trench is associated with a complex transition from the Lesser Antilles frontal subduction zone between the South American ...
Milwaukee Deep, also known as the Milwaukee Depth, is the deepest part of the Puerto Rico Trench, constituting the deepest points in the Atlantic Ocean. [1] Together with the surrounding seabed area, known as Brownson Deep, the Milwaukee Deep forms an elongated depression that constitutes the floor of the trench.
The South Sandwich Trench is a deep arcuate trench in the South Atlantic Ocean lying 100 kilometres (62 mi) to the east of the South Sandwich Islands. It is the deepest trench of the Southern Atlantic Ocean, and the second-deepest of the Atlantic Ocean after the Puerto Rico Trench.
Near the equator, the Mid-Atlantic Ridge is divided into the North Atlantic Ridge and the South Atlantic Ridge by the Romanche Trench, a narrow submarine trench with a maximum depth of 7,758 m (25,453 ft), one of the deepest locations of the Atlantic Ocean. This trench, however, is not regarded as the boundary between the North and South ...
The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of 10,994 m (36,070 ft) below sea level. Oceanic trenches are a feature of the Earth's distinctive plate tectonics .
Lying about 75 mi (121 km) north of Puerto Rico in the Atlantic Ocean at the boundary between the Caribbean and North American plates is the Puerto Rico Trench, the largest and deepest trench in the Atlantic. The trench is 1,090 mi (1,750 km) long and about 97 km (60 mi) wide. At its deepest point, named the Milwaukee Depth, it is 27,493 ft ...
The hadal zone, also known as the hadopelagic zone, is the deepest region of the ocean, lying within oceanic trenches.The hadal zone ranges from around 6 to 11 km (3.7 to 6.8 mi; 20,000 to 36,000 ft) below sea level, and exists in long, narrow, topographic V-shaped depressions.
The trench has a depth of 7,761 m (25,463 ft), is 300 km (190 mi) long, has an average width of 19 km (12 mi), and allows for a major circulation of deep-ocean-basin water from the west Atlantic to the east Atlantic basins. Deep water flow through the trench is from west to east with a rate of 3.6 Sverdrups (million m 3 /s) of 1.57 °C (34.83 ...
