Mesophotic reefs are little-known ecosystems that range from 30 to 150 meters (100 to 500 feet) below the ocean’s surface.
A new study has cast doubt on the extent to which mesophotic reefs may be a refuge for shallower species hit by overfishing, warming waters and extreme weather.
It finds that mesophotic reefs are just as vulnerable as shallower reefs to warming seas and ocean acidification — both impacts of climate change — and storm damage.
Climate change remains the gravest threat to coral ecosystems, both shallow and mesophotic.
