Below the whitecaps breaking on the sea surface, so-called internal waves ripple through the water. These waves can long distances, but rarely does evidence of their existence surface — unless you're looking down from space, that is.
This photograph, taken on Jan. 18 by a crewmember on the International Space Station, shows internal waves north of the Caribbean island of Trinidad, as featured by NASA's Earth Observatory. From space, the appearance of the waves is enhanced due to reflected sunlight, or sunglint, aimed back at the space station, making the waves visible to an astronaut's camera.
