Milwaukee Deep at (), 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 at (). Milwaukee Deep Milwaukee Deep, also known as The Milwaukee Depth, () is the deepest part of the Atlantic Ocean and is part of the Puerto Rico Trench. It has a maximum depth of at least . It is just north of the coast of Puerto
Ocean current by varying temperatures and salinity which affect the density of the water, which in turn, defines each oceanic region. Because the movement of deep water in ocean basins is caused by density-driven forces and gravity, deep waters sink into deep ocean basins at high latitudes where the temperatures are cold enough to cause the density to increase. Ocean currents are measured in sverdrup (sv), where 1 sv is equivalent to a volume flow rate of per second. Surface currents are found on the surface of an ocean, and are driven by large scale wind currents. They are directly affected by
