Open ocean convection is a process in which the ... are reported to be several hours to several days. [3] ... γ and β are found to be equal to 3.9 ± 0.9 and 12 ± ...
This was sufficient to allow computing of spreading rates over the last 700,000 years on many mid-ocean ridges by locating the closest reversed crust boundary to the crest of a mid-ocean ridge. [11] Marine magnetic anomalies were found later to span the vast flanks of the ridges. [ 9 ]
Harry Hammond Hess (May 24, 1906 – August 25, 1969) was an American geologist and a United States Navy officer in World War II who is considered one of the "founding fathers" of the unifying theory of plate tectonics.
Enhanced surface (upper level) westerly winds occur near the west (east) side of the active convection. [5] Ocean currents, up to 100 metres (330 ft) in depth from the ocean surface, follow in phase with the east-wind component of the surface winds. In advance, or to the east, of the MJO enhanced activity, winds aloft are westerly.
Forced convection: when a fluid is forced to flow over the surface by an internal source such as fans, by stirring, and pumps, creating an artificially induced convection current. [ 3 ] In many real-life applications (e.g. heat losses at solar central receivers or cooling of photovoltaic panels), natural and forced convection occur at the same ...
[1] [3] The scientists' goal was to prove that there was life in the deepest parts of the ocean. [3] Using a sounding rope, dropped over the edge of the ship, the team was able to capture ample amounts of data. Part of their discovery was that the deepest part of the ocean was not in the middle.

Scientists believe they’ve discovered an ancient ocean floor comprising a new layer between Earth’s mantle and core.
Mantle convection is the slow creeping motion of Earth's rocky mantle caused by convection currents carrying heat from the interior of the Earth to the surface. [33] It is one of 3 driving forces that causes tectonic plates to move around the Earth's surface.
