Aono Raina High Sea

Aono Raina High Sea surrounds the Line Islands, a chain of atolls and coral islands stretched across the central Pacific south of Hawaii. The Gilbertese name Aono Raina identifies the equatorial island group. Reef flats, lagoons and narrow passages break the ocean into scattered landfalls, while ocean swells, currents and long distances make navigation the decisive skill for anyone moving between them.

The Line Islands include Kiritimati, one of the largest coral atolls in the world, together with Teraina, Tabuaeran and smaller uninhabited reefs. Archaeological remains of marae platforms and village complexes survive on several islands. They show occupation from at least the fourteenth century and suggest that some communities remained permanently or seasonally settled. These landfalls supported fishing, gathering and exchange across a sea with few fixed points.

European ships entered the chain during the eighteenth century, and its position near major Pacific tracks gradually brought explorers, whalers and traders. Coconut groves supplied copra, while reefs and lagoons provided fish. None of these activities changed the basic geography: settlements were small, water and food depended on the reef, and every voyage relied on winds and currents. The surrounding sea linked the atolls while preserving the isolation of each lagoon.
