YOUR SHOT | WATER Gavin Marchio Sydney, Australia Thousands of tons of dense dust made news when it blanketed parts of Australia last fall. To "capture the amazing scene," the 45-year-old Marchio set up his camera and tripod beneath the Sydney Harbour Bridge at the break of a deep-red dawn. Ethan Daniels Berkeley, California Relaxing between dives off Palau's Ulong Island, Daniels, 37, saw a germinating coconut bobbing in clear, shallow water along an empty beach. The sight made him reach for his camera---and reminded him of the many ways different species can take root in a new land.
