Sediments in Blue Mud Bay, Australia13.4S 136.1E
Sediments frame the coast of the Gulf of Carpentaria, in Australia, giving it a golden hue that progressively fades to green and then turquoise as they diffuse into the gulf. Visible in the upper left quadrant, west of the island of Groote Eylandt, is Blue Mud Bay.
The bay, greenish-blue from sediments, as its name suggests, is a large, shallow, partly enclosed bay on the eastern coast of Arnhem Land, in the Northern Territory of Australia, facing Groote Eylandt on the western side of the Gulf of Carpentaria. The bay is about 90 km in length and up to 35 km in width. Its 45 km wide mouth stretches from Cape Shield in the north-east to Cape Barrow in the south-west, with Woodah Island in between. It has a diverse inner coastline of many small bays, inlets, headlands and islands, bordered by intertidal mudflats and mangroves merging into freshwater floodplains.
