Where the Oceans Meet

 

A remarkable video from a cruise ship of where the Atlantic Ocean and the Pacific Ocean meet. The Straights of Juan del Fuego, at the tip of South America, (South of Argentina and Chile) is where the Atlantic Ocean and the Pacific Ocean meet.

However, their waters do not mix.  The video is incredible.  So... why don't the waters mix?

Because there is a huge difference in salinity.  The clear water of the Pacific Ocean that comes from melting glaciers, is cool and low in salt, while the water from the Atlantic Ocean has a high salt concentration from many rivers along South America.  Therefore, the two oceans have different densities, which makes the waters almost impossible to mix.

In the video, you can also tell which ocean is which.  If you look in the background near the end of the video,  you'll see a landmass in the distance, that's South America so the cruise ship was heading from West to East.  The Pacific is Blue. and the Atlantic is muddy green.
