In 2026, Australian researchers combined satellite images and desktop mapping to uncover more than 1,000 previously uncharted coral reefs

In a groundbreaking study, researchers have unveiled over 1,000 previously hidden coral reefs off the northern coast of Australia, utilizing innovative satellite imaging techniques. This extensive mapping has exposed underwater ecosystems that were once shrouded in sediment. Importantly, these reefs, similar in significance to the Great Barrier Reef, highlight their critical role in marine biodiversity and coastal defense.
