Where two seas of different densities collide, taken off the Alaskan coast.
It still amazes me that this exists.
who took this
okay, first of all, this is not where two seas collide, this is just a very dark beach. second, it was taken in the southern coast of iceland, not alaska. check the source! http://www.flickr.com/photos/smari/750306571/in/photostream/
the original picture of the merging oceans in alaska is this one: http://www.flickr.com/photos/kentsmith9/4955772693/ and it’s not really two oceans but the ocean and the melting water of a glacier. you can check out a nice explanation of the phenomenom here: http://www.alaskadispatch.com/article/mythbusting-place-where-two-oceans-meet-gulf-alaska
aaaaand that’s all my lesson for the day :)
