Strømmene i oceanerne er forbundet i en form for 'transportbånd', som transporterer varme rundt på planeten. Drivkraften bag strømmen er til dels forskelle i densiteten af vand i oceanerne, skabt af forskelle i temperatur og salinitet, dette kaldes den termohaline cirkulation

This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice. As a consequence the surrounding seawater gets saltier, because when sea ice forms, the salt is left behind. As the seawater gets saltier, its density increases, and it starts to sink 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 adjective thermohaline derives from thermo-referring to temperature and -haline referring to salt content, factors which together determine the density of sea water A shutdown or slowdown of the thermohaline circulation is a hypothesized effect of global warming on a major ocean circulation.. Data from NASA in 2010 suggested that the Atlantic Meridional Overturning Circulation (AMOC) had not slowed down, but may have actually sped up slightly since 1993. A 2015 study suggested that the AMOC has weakened by 15-20% in 200 years

The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. These two regions don't mix except in certain special areas, which creates a large slow current called the thermohaline circulation.This website, presented by NASA's Global Precipitation Measurement (GPM) mission, provides students and educators with resources to learn about. The sinking that drives the thermohaline circulation depends critically on the water being sufficiently cold and salty. Therefore, any factor that changes the state of the conditions for circulation, can result in a slow-down of the thermohaline circulation, and thereby dramatically influence the climatic state and driving further climate change

Ordet er sammensat af thermo for varme og haline for havsalt. Det globale kredsløb kaldes også havenes store transportbånd. Den thermohaline cirkulation har stor betydning for Jordens klima

Et nyt studie har skabt overskrifter verden over samt ansporet til nyhedsreportager, der advarer om risikoen for, at Europa og USA er på vej mod en 'lang frostperiode' eller en 'is-apokalypse'.. Studiet, der er publiceret i Science Advances, har afsløret, at de eksisterende klimamodeller måske overvurderer stabiliteten af de nordatlantiske havstrømme, den såkaldte 'termohaline cirkulation. Thermohaline Circulation. Driven by density and salinity differences-- heating and cooling at the surface (upwelling and downwelling) and freshwater (evaporation/sea ice formation) cause water to move. Wind Driven Currents Thermohaline circulation: Thermohaline circulation, the component of general oceanic circulation controlled by horizontal differences in temperature and salinity. It continually replaces seawater at depth with water from the surface and slowly replaces surface water elsewhere with water rising from deeper depths What is the thermohaline circulation (THC)? As opposed to wind-driven currents and tides (which are due to the gravity of moon and sun), the thermohaline circulation (Fig. 1) is that part of the ocean circulation which is driven by density differences. Sea water density depends on temperature and salinity, hence the name thermo-haline One of the most well-known climate patterns that we have come to recognize and better understand is the El Niño. Every three to seven years during the months of December and January, the balance between, wind, ocean currents, oceanic and atmospheric temperature and bioshpere breaks down, resulting in a severe impact on global weather

Ekman spiral a theoretical consideration of the effect of a steady wind blowing over an ocean of unlimited dept and breadth and of uniform viscosity; result is a surface flow of 45 degrees to the right of the wind in the NH; water at increasing depth below the surface will drift in directions increasingly more slowly and to the right until at about 100 m depth it may move in a direction. Scientists across the globe are trying to figure out why the ocean is becoming more violent and what, if anything, can be done about it. Ocean currents, including the ocean conveyor belt, play a key role in determining how the ocean distributes heat energy throughout the planet, thereby regulating and stabilizing climate patterns [7] Initially, the d18O record from each site, measured on benthic foraminifera, was correlated to the chronology of Shackleton et al. [1990] (Figure 2)

This activity helps the students to visualize the effects of temperature and salinity on water density, and the resulting thermohaline circulation. Important processes visualized in this demonstration are upwelling, downwelling, and the formation of haloclines, thermoclines and pycnoclines. In addition, mixing by advection is clearly demonstrated Samtidig sørger processen for at holde gang i den globale cirkulation og Grønlandspumpen er således en nødvendighed for Golfstrømmens transport af varmt vand til at mildne de Nordvesteuropæiske vintre, sammenlignet med vintrene på de samme breddegrader i Canada og Sibirien -Den thermorhaline cirkulation? Der bliver mere vand, og vandet vil blive koldere. -Vandets saltindhold? Når havvandet fryser til is, fryser saltet ikke med. Saltet presses ud af isen og ender i vandet igen. Et højt saltindhold gør vandet tungere. Så saltindholdet vil alts
