Marshall Islands atolls named first national marine sanctuary

Remote Pacific ecosystems remain intact

A new study published in Frontiers in Marine Science identifies two coral atolls as some of the most intact ecosystems remaining globally. Researchers from the University of Hawai'i conducted extensive monitoring across land, sea and sky environments between 2023 and now. The team used scuba gear, underwater video cameras and deep-sea deployments to assess biodiversity levels in these remote locations. Dr Alan Friedlander served as chief scientist for Pristine Seas during this joint expedition effort.

Bikar and Bokak differ biologically

The northernmost atolls lie 116 kilometers and 385 kilometers from the nearest inhabited island respectively. Bikar supports almost exclusive sea turtle nesting with 132 recorded green sea turtle nest pits found there. Bokak features higher reef fish biomass while supporting coral-dominated reef communities instead of algae. Scientists recorded 15 seabird colonies, 266 groups of reef fish and 79 groups of deep-sea fishes across both sites.

Community safeguards fragile habitats

The community of Utirik Atoll has traditionally safeguarded these fragile ecosystems for decades before official protection began. Two years after the initial assessment, authorities declared the area a sanctuary under the Reimaanlok vision framework. This national conservation plan ensures island life thrives while protecting marine and terrestrial resources for future generations.
