Lizard Island Research Station Documents Major 2022 Coral Spawning Event on Great Barrier Reef

Researchers at the Lizard Island Research Station observed a significant coral spawning event in November 2022 on the Great Barrier Reef. The mass spawning occurred primarily on November 12 at North Point, following the full moon on November 8. Scientists from the station monitored the phenomenon over two nights, noting that many hard coral species release egg and sperm bundles simultaneously in an annual reproductive event. The timing is influenced by lunar cycles and light conditions, with researchers using artificial lighting manipulation in aquarium studies. The event represents a critical annual opportunity for coral genetic mixing and reef regeneration.
