Coral core from Olowalu Reef reveals 250 years of climate change
Original: Ancient Coral Core from Olowalu Reef Reveals 250 Years of Climate and Land-Use Change
Scientists have extracted an ancient coral core from Olowalu Reef on Maui, Hawaii, capturing roughly 250 years of environmental history. The core's chemical makeup records shifts in ocean temperature, rainfall and land-use practices, offering a long-term baseline of how runoff and climate change have affected the reef. Researchers say it will help guide restoration and conservation of Hawaiian reefs.
Why now: A newly reported centuries-long reef record offers rare historical evidence of climate and land-use impacts on Hawaiian corals.
