Alex Mustard - Sand Ripples Advancing

As a wave washes over a shallow sand bar, the sand along the top of the ripples is washed up into the water column as little clouds and transported horizontally allowing the sand ripples to advance. I took this with a fisheye lens and purposely placed the horizon high in the frame to add some distortion to this scene.

Location: Cayman Islands, Caribbean Sea.
