In the Gulf of Alaska, there is an interesting occurrence where two different kinds of water come together but don’t mix. This special event is called a “marine-estuarine front.” In this area, freshwater from glaciers and rivers mixes with saltwater from the ocean.
Because the freshwater is less dense, it stays on top of the saltwater. You can see a visible line where the two types of water meet because they have different colors and clarity.
It’s a beautiful sight that shows how our oceans can have different layers and characteristics.
