"One of the orbiting windows to our world, an Earth-observing satellite named Envisat, took this image in early December 2011 showing a phytoplankton bloom swirling into a figure-8 in the South Atlantic Ocean about 600 km east of the Falkland Islands. The European Space Agency says that since the phytoplankton are sensitive to environmental changes, it is important to monitor and model them for climate change calculations and to identify potentially harmful blooms. Sensors on the satellites can monitor these algal blooms and make an initial identification of its species and toxicity.
Blooms like this are common in the spring and summer, and it is currently summer in the southern hemisphere.
These microscopic organisms are the base of the marine food chain, and play a huge role in the removal of carbon dioxide from the atmosphere and the production of oxygen in the oceans. Besides being beautiful to see from space, phytoplankton help regulate the carbon cycle, and are important to the global climate system."
