WebbAlthough this process is relatively slow, tremendous volumes of water are moved, which transport heat, nutrients, solids, and other materials vast distances. Thermohaline circulation also drives warmer surface waters poleward from the subtropics, which moderates the climate of Iceland and other coastal areas of Europe. WebbWhat are Ocean Currents? Ocean currents are defined as the large-scale movements of water in the oceans in a definite direction. If the mass of the water moving on the surface of an ocean is broad, slow, and shallow, it is termed drift. But how do we measure ocean current?

As CNN reports this morning, ocean currents now appear to be slowing down, not speeding up, due to global warming. And, remember, as CNN tells us, climate scientists predicted this all along. Webb10 apr. 2024 · We're talking about changes that take 1,000 years, but are happening in just a few decades. Research carried out by Australian scientists and published in Nature, in fact, has highlighted how the melting of Antarctic ice could, in just 3 decades, lead to a rapid slowdown of deep currents. In fact, currents could slow by 40% by 2050.

Webb8 okt. 2009 · 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. The ocean currents, the movement of the ocean in the surface layer, are driven mostly by the wind.
