Scientists hoping to better understand the fragile ecosystem on and around Antarctica have begun delegating data collection to satellite-guided robotic subs. The hope is that these sea gliders, which can dive hundreds of meters and stay in the water for months at a time, will help to unlock the secrets of phytoplankton blooms that nourish the organisms in Antarctica's Ross Sea for a few months each year before mysteriously disappearing.
