A video taken by travelers across the ocean where the Pacific and Atlantic meet, has been making rounds on the internet.
The place is informally dubbed as “the place where two oceans meet.” Not only because it is a rare view, but people are more curios as to the reason why they do not mix.
The explanation to this is quite simple, though there are many misconceptions regarding this phenomena.
The two types of water do not mix, simply because their densities differ due to difference in their salinity.
Ken Bruland, professor of ocean sciences at University of California-Santa Cruz, once examined hoe eddies – slow moving currents – ranging into the hundreds of kilometers in diameter, swirl out from the Alaska coast into the Gulf of Alaska.
“Glacier rivers in the summertime are like buzzsaws eroding away the mountains there,” Bruland said. “In the process, they lift up all this material — they call it glacial flour — that can be carried out.”
Once these glacial rivers pour out into the larger body of water, they’re picked up by ocean currents, moving east to west, and begin to circulate there. This is one of the primary methods that iron – found in the clay and sediment of the glacial runoff – is transported to iron-deprives regions in the middle of the Gulf of Alaska.
To answer the question as to whether these oceans mix, Bruland said, “They do eventually mix, but you do come across these really strong gradients at these specific moments in time.”
Such boarders are never static, he added, as they move around and disapper altogether, depending on the level of sediment and the whims of the water.
