Undersea Gliders May Help Oceanographers Understand "Dead Zones"


Most hypoxic or dead zones are caused by human activity, due to river runoff and an overabundance of nutrients from land that flow into oceans, gulfs or estuaries. The nutrients fuel excessive growth of phytoplankton. When these tiny plants die, their decay uses up the water's oxygen supply.
