Palmyra Atoll is one of the Northern Line Islands (southeast of Kingman Reef and north of Kiribati Line Islands), located almost due south of the Hawaiian Islands, roughly one-third of the way between Hawaii and American Samoa. The nearest continent is almost 5,400 kilometers (3,400 miles) to the northeast. The atoll is 4.6 sq mi (12 kmĀ²), and it is located in the equatorial Northern Pacific Ocean. Its 9 mi (14 km) of coastline has one anchorage known as West Lagoon.
It is an unoccupied equatorial Northern Pacific atoll administered as an unorganized incorporated territory by the United States federal government. The 12-square-kilometer (4.6 sq mi) territory hosts a variable temporary population of 4-25 "non-occupants", namely staff and scientists employed by various departments of the U.S. Government and by The Nature Conservancy, as well as a rotating mix of Palmyra Atoll Research Consortium scholars pursuing research.
