![]() ![]() Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. 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. However, salt ponds have also been successfully converted to wetlands, and the shallow ponds can support shellfish and bird populations.Īstronaut photograph ISS010-E-6681 was acquired Novemwith a Kodak 760C digital camera with a 180 mm lens, and is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Group, Johnson Space Center. The hypersaline conditions are toxic to preexisting ecosystems in and around the converted land, and valuable coastal wetlands may be impacted by flooding, changing water levels and salinities. Commercial solar salt ponds are frequently controversial components of coastal ecosystems. Global demand for salt is on the rise, primarily because salt is a basic feedstock to the chemical industry (the largest salt consumer).

Australia Country Nation Cultural Vector Seamless Pattern. Complex chemical and biological adjustments occur in the system each time the configuration of ponds is changed. Today, this salt farm comprises over 50 ponds’the newest pond is the outermost pond in Useless Inlet, which provides the first evaporation cycle to increase the salinity of the water prior to entering the next pond. This particular salt farm opened in 1967 and expanded operations in the 1990s. The salt (sodium chloride) is produced when ponds are repeatedly flooded with seawater, which is progressively concentrated by evaporation. This image shows large solar salt works developed in Useless Loop and Useless Inlet, Shark Bay, Western Australia (for a regional image of Shark Bay, see Phytoplankton in Shark Bay ).
