New underwater and coastal surveys in Pohnpei, Federated States of Micronesia, have identified extensive star-shaped coral pavements submerged near ancient basalt ruins. These platforms are believed to be the sites of "Deep-Reef" festivals, where the community honored marine deities during specific lunar alignments. The coral used for the pavements was specifically selected for its branching shapes, which mimic the constellations used by ancient navigators.
Researchers found evidence of communal shell-trumpeting and maritime offerings of pearl-shell jewelry within the crevices of the coral structures. These festivals likely served as a time of maritime truce between warring clans, allowing for the shared use of rich fishing grounds. The discovery highlights the deep integration of celestial navigation and marine ecology in ancient Micronesian cultural heritage.
