The Gulf Stream Explained

  • Published: 11 October 2013
  • Learn about the role of the sea in global warming.

    The global conveyer belt is part of the large-scale ocean circulation that is driven by differences in the density of the waters. It plays a key role in keeping the climate at balance and Europe warm. Global warming may change it forever with unforeseeable consequences.

    Short videos, explaining things. For example Evolution, the Universe, Stock Market or controversial topics like Fracking. Because we love science.

    We would love to interact more with you, our viewers to figure out what topics you want to see. If you have a suggestion for future videos or feedback, drop us a line! :)

    That was super useful! Just one thing: 2:26 the salt content doesn't rise by water evaporating (it's way to cold for that) but by water turning into ice which increase the concentration of salt in the water. It also increase in density turning into colder water as explained at the beginning of the video.

      Sorry scientists, I have a hard time believing in all of this.
      How is it possible to track this currents in the first place.
      Seriously. How? In this large scale.
      You just made a pretty videos with arrows pointing the currents ...

      I just watched a documentary on Netflix, which claims, millions of pounds of sand travel thousands of kilometers through air, from Africa to the amazon.

      I don’t believe that either.

        You should believe the scientists who have put in the time and effort to understand these, not disbelieve it due to your ignorance. I you really wanted to know, just research it. Search engines are at your fingertips.

        In any case, I used to work for the NOAA, and we use many buoys to track several aspects of the ocean at many depths. Using this information, we can tell where the current is moving and how its properties change from one location to another. This is just one of many ways we can tell. We also have satellite observation technology and floating GPS trackers.

        Just google "NOAA How Are Currents Measured" and you will get a very in depth article about how it's done.

      Im doing a project in college, in which Im making an engine using the thermohaline circulation as inspiration. And from this, Ive found one problem: the circulation system doesn't work as an engine, it works as a heat exchanger... the difference may not matter to the lay man, but still...

                    So, saltier water is denser than less salty water... and the very salty Gulf Stream stops because it won't fall when the ice caps melt more and cause the surrounding water to become less salty?
                    Did I understand what they said correctly?

                      at 1:25 a rise in salt content? did he meant to say a rise in the salt concentration (due to water evaporation and salt content staying the same)?
