From World War Ii Outposts to Pacific Sanctuaries: the Changing Relevance of the U. S. Minor Outlying Islands
The physical land of these outlying islands faces precarious conditions. Kingman Reef sits mostly underwater at high tide. Baker and Jarvis rise barely a few meters above sea level, offering zero natural fresh water, no soil depth, and scrub brush vulnerable to ocean overwash.
Palmyra Atoll stands as a rare exception of sustained scientific habitation. The Nature Conservancy, operating alongside federal agencies, manages a small research station housing visiting marine biologists, climatologists, and ecologists. Because Palmyra was spared heavy agricultural development and lacks native human populations, its lagoons serve as an undisturbed baseline for how coral reef structures respond to warming sea surface temperatures, ocean acidification, and invasive species eradications without local land-based pollution.
Farther west, the celestial mechanics of solar eclipses occasionally draw rare permitted vessels toward these waters. When the path of totality crosses the central Pacific, private expeditions chart courses near the maritime borders of Howland or Baker, capturing views of astronomical events across horizons unmarred by modern light pollution. Yet even during these rare visits, researchers confront the mounting reality of shifting oceanic tides. As sea levels rise throughout the twenty-first century, the physical viability of these atolls will test the legal doctrines governing whether a submerged reef continues to anchor an Exclusive Economic Zone under maritime law.
