| Rowley Shoals, Timor Sea: This astronaut photograph highlights
the coral
reef atolls known as Rowley Shoals, located in the southwestern
Timor Sea. Three reef areas make up the shoals—Mermaid Reef, Clerke
Reef, and Imperieuse Reef—which extend approximately 100 kilometers
(62 miles) from northeast to southwest. Only Clerke Reef and
Imperieuse Reef have white sandy islets (or cays) that remain above
water. Imperieuse Reef also has the only permanent man-made
structure: a lighthouse on Cunningham Islet, a cay at the northern
end of the reef. Rowley Shoals is located off the northwestern Australia coastline, approximately 300 kilometers (185 miles) west of the city of Broome. Since the late 1970s, fishing and diving expeditions have frequented the atolls. Clerke and Imperieuse Reefs are part of the Rowley Shoals Marine Park, established in 1990. Mermaid Reef is managed as the Mermaid Reef Marine National Nature Reserve, established in 1991. The biodiversity of the atolls is impressive, with 233 coral species and 688 fish species more typical of Southeast Asia than other Western Australian reef ecosystems. Species include staghorn coral, giant clams, giant potato cod, maori wrasse, mackerel, and tuna. In addition, Bedwell Island (a cay in Clerke Reef) hosts a colony of red-tailed tropicbirds, as well as species of shearwaters, sea eagles, terns, plovers, and egrets. |
