February 7, 2013. In the ocean there are more waves than it seems at first glance.

In the lower part of the white crests breaking the sea surface, it is so-called inner ripple waves through water. These waves can travel great distances, but, nevertheless, the evidence of their existence is rarely found on the surface — but if you look out of space, you can see them.

This photo was taken on January 18 members of the crew of the International Space Station. It shows internal waves north of the Caribbean island of Trinidad, as specified Earth Observatory, NASA project. When viewed from space, visibility is enhanced by the wave reflection of sunlight, or solar flare directed back to the space station, resulting in a wave of camera detected astronaut.

Most embossed wave one can seen in the upper left corner of the photo, they move to the north-west due to tidal currents in Trinidad, according to the data of the Earth Observatory. Another set one can seen moving from the north-east, most likely, he appeared on the edge of the continental shelf, where seabed drops sharply,  according to the website of the Observatory.

Internal waves seen in all the oceans and in the atmosphere, according to data of the Laboratory of Experimental and Nonlinear Dynamics at the Massachusetts Institute of Technology. They arise because of differences in the density of the layers of water (due to changes in temperature or salt content, for example), when the water moves through the special relief such as seamounts and continental shelf. The waves are huge size, up to 100 meters (about 330 feet) in width and reach hundreds of kilometers, according to the release of the University of Massachusetts on a new method of studying the waves.

One can to consider and milk sediment plume at the edge of the photos on the north-west. The precipitate forms the equatorial current that moves from west to east, from Africa to the Caribbean side, and pumped strong easterly winds, according to the website of the Observatory of Earth.
