Ocean Dead Zones

Oceanographers are using robotic undersea "gliders" to study "dead zones" in the seas. Agricultural runoff, carried to the ocean by rivers, can cause plankton blooms which lower oxygen levels in the water. Lacking oxygen, many marine creatures die. Climate change may influence the frequency and extent of these blooms.
