Summary edit

Description
English: This wide field-of-view image photographed by an Expedition 38 crew member on the International Space Station shows an east-west swath of the southwestern Indian Ocean.
  • Two remote islands, part of the French Southern and Antarctic Lands, appear in the center of the image. Possession Island (right center) and East Island (center) are both only 18 kilometers long. A smaller island, Ile aux Cochons (Pigs Island), lies 100 kilometers to the west. Each island has set up V-shaped trains of waves, like bow waves, as the air flows over the islands from the west (right to left). The bow-wave patterns are overlaid on the low regional stratus (blanket) cloud that is so common in the southern Indian Ocean at 50 degrees south latitude.
  • This view was taken from more than 400 kilometers above the sea surface and reveals relationships that could not be readily understood by someone standing on one of the islands. For example, larger and higher islands produce larger waves. So the largest are being generated by Possession Island (934 meters above sea level at the highest point), and East Island, versus much smaller waves developed downwind of the tiny Ile de Pingouins (340 meters above sea level high, invisible below the cloud deck).
  • Other patterns also can be detected. Waves in an upper layer can be seen casting shadows onto a lower layer (lower left). In the top half of the image the waves are making thicker and thinner zones in the clouds of the lower layer. Wave trains from Possession Island and Ile aux Cochons are interacting in a cross-hatch pattern (center).
