Marsh Island, Louisiana

Marsh Island, located along the southwestern coastline of Louisiana, is a remnant of an abandoned lobe of the Mississippi River Delta formed approximately 5,000–7,500 years ago. It is composed primarily of organic-rich muds and brackish marsh vegetation, but some peat (layers of vegetation that have partially decomposed while submerged in water) is also present.

The featured astronaut photograph ISS015-E-7725 was acquired May 11, 2007, by the Expedition 15 crew with a Kodak 760C digital camera using a 400 mm lens. The image is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Laboratory, Johnson Space Center. The image in this article has been cropped and enhanced to improve contrast. The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth.
