Emperor penguins head for the open ocean in search of food. The brownish patches above them are microalgae that cling to the sea ice and start to photosynthesize in spring. The photographer’s day camp was on one of these floes.

Third place. I really like this different take on flow visualization. Though it’s not a close up of the flow itself, it still shows the disturbance the penguins make in the water. The composition of the photo is also really nice.
