Mystery behind Moana: After 1,700 years, why did Polynesians suddenly sail east?
Archaeologists are investigating the 'long pause' in Polynesian migration, a 1,700-year period where expansion into the Pacific stalled. New climate evidence is being analyzed to explain why these voyagers suddenly resumed their eastward migration between 900 and 1100 AD.
Why it matters
Understanding historical migration patterns provides insight into how ancient civilizations adapted to climate shifts and maritime challenges.

The same question drives both the plot of Moana and decades of archaeological research: why, after centuries of relative stability, did Polynesian voyagers suddenly begin settling islands thousands of kilometres away across the Pacific?
The latest Moana movie is a live-action adaptation of a Disney animated movie of the same name. While the films are fictional, they draw inspiration from the rich seafaring heritage of Polynesian peoples, whose ancestors undertook one of the greatest episodes of maritime exploration in human history.
New climate evidence may help us understand why they embarked on these voyages.
