Christ, how bloody weird is that picture? I’ve been showing everyone that for two days. It turns out that this strange natural phenomenon occurs when sediment-heavy water enters the ocean from valleys and rivers. There is a density difference, which occurs because of the salinity and temperature variation of each ocean. They are mixing together, but deep beneath the surface. This occurs at Cape Horn, the southernmost headland of the Tierra del Fuego archipelago of Southern Chile and in the Bay of Alaska and it’s really bloody weird.
