River Plumes Threaten Great Barrier Reef

Published March 29, 2007
In late February 2007, NASA satellite images revealed that even the outer portions of the Australia’s Great Barrier Reef can be bathed in land-based pollution carried far offshore by plumes of river water. Conventional thinking was that river plumes affected only the lagoon and the inner portions of the reef. But images from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite verify a new theory that not even the outer reefs are spared the impact of land-based pollution, which includes excess sediment, fertilizers, and pesticides.

Thames River Plume in the North Sea
3600 x 4800 2 MB - JPEG
Published March 27, 2007
Though the River Thames pours into the North Sea in southeast England, the river does not end there. Its plume of fresh water, colored tan by the earth picked up on its journey across England, flows through the dark blue waters of the North Sea along the coast of Belgium, the Netherlands, and Germany before fading in a cloud of green near Denmark.
