Salton Sea

Dividing up water resources in southern California is always a controversial activity. Water allocations for the agriculture in the Imperial Valley, the Salton Sea, and the expanding urban and residential growth in San Diego County were in limbo until a recent agreement was drafted, allowing San Diego to buy conserved Colorado River water from the Imperial Valley. This astronaut photograph details an algal bloom in the Salton Sea, where such blooms continue to be a problem. They are caused by high concentrations of nutrients, especially nitrogen and phosphorous, that drain into the basin from the agricultural run-off. As the algae dies and decomposes, oxygen levels in the sea drop, causing fish kills and hazardous conditions for other wildlife.

Astronaut photographs ISS007-E-16876 and ISS007-E-17038 were taken from the International Space Station on October 9 and 11, 2003 (respectively) with a Kodak DCS760 digital camera equipped with 70 mm and 800 mm lenses. Image content was provided by Cynthia A. Evans (Lockheed Martin / Earth Observations Laboratory, Johnson Space Center). 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.
