Where the river meets the sea.
Here we can see the river water from Copper River in Alaska meet the Ocean. The river water is rich in sediment and has a lighter blue to it than the dark blue of the sea. The water does eventually mix. Sometimes this phenomenon can be seen from space. This photo is sometimes inaccurately labelled as where two oceans meet.
