How does sea ice affect global climate? NOAA's
Water below sea ice has a higher concentration of salt and is denser than the surrounding ocean water, so it sinks and moves from the surface In this way, sea ice contributes to the circulation of the global ocean conveyor beltThe global conveyor belt is a strong, but easily disrupted process Research suggests that the conveyor belt may be affected by climate change If global warming results inEffects of Climate Change NOAA's National Ocean Service

NOAA's National Ocean Service: Education Currents
Thermohaline circulation drives a globalscale system of currents called the “global conveyor belt” The conveyor belt begins on the surface of the ocean near the pole in the North Atlantic Here, the water is chilled by arctic temperatures It also gets saltier because when sea ice forms, the salt does not freeze and is left behind in2023年9月22日· The global conveyor belt includes both surface and deep ocean currents that circulate the globe in a 1,000year cycle The global conveyor belt’s circulation is the result of two simultaneous processes:Ocean Currents and Climate National Geographic
Thermohaline Circulation NOAA's National Ocean
Currents Tutorial Thermohaline circulation begins in the Earth's polar regions When ocean water in these areas gets very cold, sea ice forms The surrounding seawater gets saltier, increases in density and sinksIt is estimated that any predefined cubic meter of water takes about 1,000 years to completely the journey along the total conveyor belt In addition, the conveyor moves an immense ring of water—more than 100 hours the flow of this Amazon River (Ross, 1995) The global ocean conveyor belt is ampere constantly poignant system of deepoceanThe Global Conveyor Belt Currents: NOAA's National Ocean Service
Thermohaline Circulation NOAA's National Ocean Service
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 deepocean 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 circulationOn a global scale, this sinking and rising of ocean water creates what scientists call the 'great ocean conveyor belt’ This conveyor belt affects the Earth's climate by driving warm water from the Equator and cold water from the poles around the Earth It takes water almost 1000 years to move through the whole conveyor belt So there youWhat are Ocean Currents? | Every Full Moon | Ocean Today

Why does the ocean get colder at depth? NOAA's National Ocean Service
Cold water has a higher density than warm water Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface The sinking and transport of cold, salty water at depth combined with the winddriven flow of warm water at the surface creates a complexThis deflection is called the Coriolis effect Click the image for a larger view Coastal currents are affected by local winds Surface ocean currents, which occur on the open ocean, are driven by a complex global wind system To understand the effects of winds on ocean currents, one first needs to understand the Coriolis force and the EkmanThe Coriolis Effect NOAA's National Ocean Service
Currents Subject Review NOAA's National Ocean Service
Global winds drag on the ocean’s surface, causing the water to move in the direction that the wind is blowing and thus create surface ocean currents Deflection of these currents by Earth’s rotation produces spiral currents called Each of the major oceanwide gyres is flanked by a strong and narrow “western boundary current
