CSIRO Imagery Shows Great Barrier Reef at Risk from River Plumes

CSIRO Media Release – 20 February 2007

Sediment run-off, appearing as browns and aquas, appears to have clouded the entire inner-reef. At the top of the photo, run-off from the Daintree River (1), a yellow-brown in colour, travels away from the coast towards Balt Reef and the Trinity Opening (2). Sediment plumes emanating from Cairns' Baron and Mulgrave Rivers can be seen merging with similar plumes from southern rivers into a plume travelling over 100kms through the Grafton Passage (3) and into the open ocean.

This image shows how the sediment plumes have travelled further, travelling beyond the reef into the ocean, but have started to disperse.
