LANGMUIRCIRCULATION
Langmuir circulation
In physical oceanography, Langmuir circulation consists of a series of shallow, slow, counter-rotating vortices at the ocean's surface. These circulations are developed when a particular type of wind blows steadily over the sea surface. Irving Langmuir discovered this phenomenon after observing windrows of seaweed in the Sargasso Sea in 1927. Langmuir circulations usually circulate water with a depth of no more than, which does not allow upwelling to bring nutrient-rich waters from the pycnocline – typically with a depth of more than – to the ocean surface.The above text is a snippet from Wikipedia: Langmuir circulation
