This phenomenon is due to the differences in temperature, speed, and amount of dissolved sediments in the waters of the two rivers. The Rio Negro flows at near 2 km/h (1.2 mph) at a temperature of 28 °C (82 °F), while the Rio Solimões flows between 4 and 6 km/h (2.5–3.7 mph) at a temperature of 22 °C (72 °F). [ 1 ]
If there were no mixing in the ocean, the deep ocean would be a cold stagnant pool with a thin warm surface layer. [ 16 ] While the meridional overturning circulation (also referred to as the thermohaline circulation ) redistributes about 2 PW of heat from the tropics to polar regions, the energy source for this flow is the interior mixing ...
Maps exhibiting the world's oceanic waters. A continuous body of water encircling Earth, the World/Global Ocean is divided into a number of principal areas. Five oceanic divisions are usually recognized: Pacific, Atlantic, Indian, Arctic, and Southern/Antarctic; the last two listed are sometimes consolidated into the first three.
The stratified configuration of the ocean can act as a barrier to water mixing, which impacts the efficiency of vertical exchanges of heat, carbon, oxygen, and other constituents. Thus, stratification is a central element of Earth's climate system. Global upper-ocean stratification continued its increasing trend in 2022 and was among the top ...
Brackish water, sometimes termed brack water, [1] [2] is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root brak.
Parting of the Waters is an unusual hydrologic site at Two Ocean Pass on the Great Divide, within the Teton Wilderness area of Bridger-Teton National Forest, Wyoming, USA. Two Ocean Pass separates the headwaters of Pacific Creek, which flows west to the Pacific Ocean, and Atlantic Creek, which flows east to the Atlantic Ocean.
World map of the five-ocean model with approximate boundaries. This list of countries which border two or more oceans includes both sovereign states and dependencies, provided the same contiguous territory borders on more than one of the five named oceans, the Pacific, Atlantic, Indian, Southern, and Arctic.

Open ocean convection is a process in which the mesoscale ocean circulation and large, strong winds mix layers of water at different depths. Fresher water lying over the saltier or warmer over the colder leads to the stratification of water, or its separation into layers. Strong winds cause evaporation, so the ocean surface cools, weakening the ...
