The isolated atoll has been under the control of the U.S. military since 1934.[1] During that time, it was variously used as a naval refueling depot,[2] an airbase,[3] a testing site for nuclear[4] and biological weapons,[5] a secret missile base,[6] and a site for the storage and disposal of chemical weapons[7] and Agent Orange.[8] Those activities left the area environmentally contaminated. The USAF completed remediating the contamination in 2004, and today performs only periodic monitoring.[9]
The island is home to thriving communities of nesting seabirds and has significant marine biodiversity. USAF and USFWS teams carry out environmental monitoring and maintenance to protect the native wildlife.[10]
