The 100 m false-colour image of 24 June 2015 shows us Exmouth Gulf, in the north-west of Western Australia. Exmouth Gulf is a rich marine environment. It is a nursery for humpback whales, dugong and turtles. The mangrove systems on the eastern margins are areas of high primary productivity feeding and restocking both the Gulf and the famed nearby Ningaloo Reef. The Gulf sustains one of Western Australia's largest prawn fisheries.
