Not only have photographs from the shuttle given us a new perspective on the clouds, they have provided new information to oceanographers. For example, when the water surface is caught in sunglint in oblique photographs we see previously undetected swirling watery gyres and intricate wave systems known as ocean eddies. The ringlets of cloud in this photograph, taken over the Atlantic Ocean off the west coast of Africa a little north of the Tropic of Capricorn, reflect cold water eddies in the ocean below.
