    Default Is this a whirlpool or vortex?

    This looks like a whirlpool at the south of this island.

    A vortex

    Software is like entropy. It is difficult to grasp, weighs nothing, and obeys the second law of thermodynamics; i.e., it always increases.

    My mind works better in sentences with spaces and long paragraphs loose me sometimes cause I need to picture what is going on at the same time I am reading.

    I've seen this kind of thing around. You can find then in places with land that juts out like the tip of the island.

    I don't think it's a powerful 'whirlpool' sort of vortex. I'm mostly not sure if it's a collision of currents of water around the tip of the island, or a collision of wind patterns on top of the water. I THINK the most likely answer is 'wind patterns'.

    This is a classic version of it, though. The reason I think it's not a powerful whirlpool is that the wave pattern is remarkably unchanged across the top of it. I'd think if it were something within the water causing it, that the waves would be different or distorted in some way inside to reflect the water moving in different directions.

    To me that's what leaves wind as the most likely culpirt that causes the patterns on top of the water. Of course, that would make it a WIND vortex! They call them 'von Karman' vortecies, and when there are enough clouds around they make some remarkable photos. Whether that's what this is, I can't say for sure. Here's some interesting links though.

    Here's a link to search results at Visible Earth.

    A good page.

    There is no subsurface rock structure...

    if there is no substructure, what is under the water? if you look closely you can see the waves going accross the whirl pattern created by the rocks.
