Thermohaline is derived from the Greek: thermo- for heat and -haline for salt, which constitute the density of water. 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. The seawater is first heated and then undergoes chemical modification through reaction with the host rock as it continues downward, reaching maximum temperatures that … Aspects of effects of seamounts and seamount chains on oceanic flow and thermohaline structure are discussed on the basis of recent theoretical and observational findings. Thermohaline Circulation. B-Thermohaline circulation brings surface waters from the poles toward the equator, where the water then sinks and returns toward the poles. Why is the Chesapeake Bay an estuary? Relevance. along the east coast of the U.S. in the Gulf of Mexico. clockwise north of equator, counter clockwise south of equator. How to use thermohaline in a sentence. The thermohaline circulation is a term for the global density-driven circulation of the oceans.Derivation is from thermo-for heat and -haline for salt, which together determine the density of sea water.Wind driven surface currents (such as the Gulf Stream) head polewards from the equatorial Atlantic Ocean, cooling all the while … A large scale zonal ecosystem. Thermohaline circulation begins in the Earth's polar regions. D- In thermohaline circulation, surface waters become more dense as … Furthermore, thermohaline circulation can oscillate on the timescale of … Therefore, it influences the … DOC in the Mediterranean Sea. Thermohaline Circulation Implications for Climate . The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content, factors which together determine the density of sea … The large scale circulation of the oceans is similarly driven by warm water rising and colder water sinking. convection current. What is the general pattern of thermohaline circulation? What is meant by thermohaline circulation? A good example of thermohaline circulation is found where? Water is transferred around the world as part of what is known as the ocean conveyor belt system or the thermohaline circulation system. Effect of Ocean Freshening on Thermohaline Circulation THC is density-driven and depends on large differences in salinity between low and high latitude waters. Thermohaline circulation can have multiple states and oscillations over a broad range of spatial and temporal scales. The general circulation of the oceans consists primarily of the wind-driven currents. No shortcut exists for determining property fluxes from the mass circulation without knowledge of the corresponding property … Source(s): oceanography class. in the central South Pacific. Hydrothermal circulation occurs when seawater percolates downward through fractured ocean crust along the volcanic mid-ocean ridge (MOR) system. The thermohaline circulation is an impor-tant factor in the earth’s climate because it transports roughly 10 15 W of heat poleward into high latitudes, about one fourth of the total heat transport of the ocean/atmosphere circu-lation system. Figure 3: A simplified diagram showing the ocean’s thermohaline circulation. Ekman transport is part of Ekman motion theory, first investigated in 1902 by Vagn Walfrid Ekman.Winds are the main source of energy for ocean circulation, and Ekman Transport is a component of wind-driven ocean current. explain the processes that drive thermohaline circulation; interpret a T-S diagram to identify water masses; identify the major global sites of deep water formation; identify the major global water masses; explain how deep water circulates throughout the world ocean; Ocean waters are constantly in motion, from ocean-scale surface … The state of the atmosphere at a local level usually on a short Page 5/26. 2.
