Lomonosov current

The Lomonosov current (also called Lomonosov Under Current or Equatorial Under-Current) is a deep current in the Atlantic Ocean.

The Lomonosov current was discovered in 1959 during the 5th cruisecite book |first=A.G.|last=Kolesnikov|title=Techenie Lomonosova|url= |accessdate=2008-04-21|accessyear=|accessmonth=|edition=|series=|year=1966|publisher=Naukova dumka|location=Kiev|pages=p.4|language=Russian] [cite web|url=http://www.mhi.iuf.net/cruises/cruises.htm |title=Cruises of the MHI's Research Vessels |accessdate=2008-04-21 |publisher=Marine Hydrophysical Institute] of the research vessel "Mikhail Lomonosov" by an expedition of the Marine Hydrophysical Institute of the Ukrainian SSR Academy of Sciences, based in Sevastopol.

One of them, that was set at the intersection of this meridian with the equator under the thin layer of the South Equatorial Current had recorded the strong current eastwards. Its average flow speed was 96 cm per second and maximal speed — 119 cm per second. It is named after Mikhail Lomonosov.

The Lomonosov current is 200km wide, 150m thick and flows to the east. It starts near the coast of Brazil at some 5°N, crosses the equator and ends at some 5°S in the Gulf of Guinea. Its speed ranges from 60 to 130 cm per second, maximal speed being achieved at depths between 50m and 125m. [cite web|url=http://www.fao.org/DOCREP/005/T0081E/T0081E03.htm#ch3.3.2 |title=3.3.2.
