An overlooked role of the subtropical gyre circulation in regulating the AMOC - Ocean2Climate - AMOC  (Apr 14, 2022) |
|
Apr 14, 2022 · It is a common practice in Physical Oceanography to separate the Atlantic Ocean circulations into the meridional overturning and wind-driven gyre components with an assumption that the two components are largely independent of each other. An article published in Nature Communications suggests that the two components are not at all independent. The study shows that the upper-ocean water that flows northward into the North Atlantic circulates the subtropical gyre at least once before leaving the gyre. This process is necessary to achieve an increase in water density and depth through air-sea interaction (i.e., loss of heat and freshwater to the atmosphere) and interior mixing ... Read more ... |

Thermohaline Meridional Overturning Circulation on Enceladus - Ocean2Climate - AMOC  (Apr 08, 2021) |
|
Apr 08, 2021 · Enceladus is a miniature-size Saturn’s moon (Earth’s moon is about 7 times larger) known to have a deep ocean (~ 40km) beneath the thick icy crust (~20km). It has been suggested that Enceladus’s interior ocean is heated from below through hydrothermal activity, powered by tidal dissipation. The ocean should in turn carry the heat to the surface to counter balance the heat loss to the icy crust. The heating from the bottom and the cooling from the surface suggest that the ocean is in motion driven by vertical convection. A new study published in Nature Geoscience noticed a large meridional variation in the ice thickness, ranging from about 35 km in the equatorial regions ... Read more ... |
