Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. [ 1 ] [ 2 ] The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content , factors which together determine the density of sea ...
This freezing and melting of sea ice, with their accompanying salinity changes, supply local buoyancy forcing that influences ocean circulation. [ 25 ] The calving of a previously grounded ice sheet into the ocean as an iceberg as well as the melting of ice shelfs related to warm ocean water constitute a net freshwater influx, not only on a ...
The wind forcing driving this circulation therefore has an outsize influence on the freshwater transport into the Atlantic. [5] Besides, it is thought to control the stability and functioning of the thermohaline circulation. The Tasman Outflow is also directly influenced by wind forcing, especially by winds in the Southern and Pacific Ocean.
This process is significant in thermohaline circulation, contributing to the global ocean's deep water mass formation. [1] Overflows influence global climate by transporting heat and salt, impacting sea levels, and affecting marine ecosystems. Overflows are driven by differences in water density, usually due to variations in temperature and ...
Winds drive ocean currents in the upper 100 meters of the ocean's surface. However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.
Due to global warming and increased glacier melt, thermohaline circulation patterns may be altered by increasing amounts of freshwater released into oceans and, therefore, changing ocean salinity. Thermohaline circulation is responsible for bringing up cold, nutrient-rich water from the depths of the ocean, a process known as upwelling. [69]
