River terminator

Looks photoshopped, doesn’t it? 

Yeah, it’s not. 

In the Gulf of Alaska there is a liquid demarcation at the point where glacial water meets with the open ocean. The water that comes from glaciers is rich in sediment, so it becomes a light, milky color. This glacial water is eventually picked up by the currents and mixed in with the ocean water, but when it’s first introduced, there can be lines of demarcation between the two. These borders aren’t by any means permanent; they are eventually erased by the power of the slow-moving currents that circulate this dense water into the center of the Gulf of Alaska.
