Kingman Reef, Protected coral reef in Pacific Ocean, United States
Located 920 miles southwest of Honolulu, Kingman Reef includes a central lagoon measuring 5 by 9.5 miles with surrounding coral formations.
First observed in 1798 by Edmund Fanning, the reef received its name from W. Kingman who documented detailed descriptions in 1853.
The reef became a critical stopover point during the 1930s for commercial seaplane routes connecting Hawaii and American Samoa.
Access to Kingman Reef National Wildlife Refuge requires obtaining a Special Use Permit through the U.S. Fish and Wildlife Service.
The reef contains three times more species of stony corals than Hawaiian Islands, with 38 genera and 130 distinct species present.
