Western Australia’s Kimberley region, with a coastline along the Timor Sea, is pictured in this Envisat image. Off the coast in the lower left we can see a group of three coral reefs, known as the Rowley Shoals. Near the centre of the image is King Sound – a large gulf measuring about 120 km long and 50 km wide. On the upper-right side is Australia’s largest artificial lake by volume, Lake Argyle, on the Ord River.

This image was acquired on 28 September 2010 by Envisat’s MERIS instrument.
