Pacific survey finds 15 breeding seabird species, 132 turtle nests and two unusual fish observations

Some of the world's healthiest marine ecosystems may still exist in places so remote that human activity has had little influence on their wildlife and habitats. Scientists surveying two isolated Pacific atolls have documented thriving seabird colonies, green sea turtle nesting grounds, diverse fish communities and extensive coral reefs.

The findings offer a rare picture of what relatively undisturbed tropical ocean ecosystems can look like.The findings come from a study published on November 11, 2026, in Frontiers in Marine Science, titled From the sky to the deep sea: ecosystem structure and ecological integrity across the National Marine Sanctuaries of Bikar and Bokak, Marshall Islands. The research, led by marine ecologist Dr Alan Friedlander of the University of Hawai'i, examined ecosystems across two remote atolls in the Marshall Islands.
