8-day undersea mission begins experiment to improve coral reef restoration
Scientists have begun an eight-day mission, in which they are living and working at 60 feet below the sea surface, to determine why some species of coral colonies survive transplanting after a disturbance, such as a storm, while other colonies die. Coral reefs worldwide are suffering from the com...
