Skagen, where the Baltic and North Seas meet | nomad* | Scoop.it

Skagen is the northernmost point of Denmark, where the Baltic and North Seas meet. The two opposing tides in this place can not merge because they have different densities.

 

"I am pretty confident that what you are seeing is a result of the melting glaciers being composed of fresh water and the ocean has a higher percentage of salt causing the two bodies of water to have different densities and therefore makes it more difficult to mix. I'm told they will eventually mix given enough time."
