Kure Atoll or Ocean Island is an atoll in the Pacific Ocean 48 nautical miles (89 km; 55 mi) beyond Midway Atoll in the Northwestern Hawaiian Islands. The only land of significant size is called Green Island and is a habitat for hundreds of thousands of seabirds. A short, unused and unmaintained runway and a portion of one building, both from a former United States Coast Guard LORAN station, are located on the island.
