Throughout history, tidal waves have drowned us, storm surges have sunk cities, and hurricanes and cyclones--fueled by the ocean--have blown away all in their path. Today, science forecasts that the oceans are getting fiercer, rising up to reshape our coastlines and create untold devastation, social unrest, and economic crisis. Track the history and evolution of the ocean's seven deadliest zones--locations that throughout history have been the direct causes of human devastation by floods, tsunamis, hurricanes, whirlpools, ice, underwater volcanoes, and shipping graveyards. Using expedition footage, 3D animation, and commentary from leading oceanographers, we'll depict the awesome cosmic and geological fluctuations that make the oceans deadly over time.

The crushing weight of water generates the Underwater Universe's ultimate weapon: Pressure. It has banished humans from much of the world's oceans, only a handful have defied it head on and survived. The deeper man goes, the greater the power of water.

The pull of the moon and spin of the earth generates mighty forces in the oceans that sweep relentlessly around the planet. Four of the Underwater Universe's most powerful tides and currents pose the greatest potential threat to mankind.

The Underwater Universe generates three types of deadly waves, each bigger and more destructive than the last: Rogue, Monster, and Tsunami. This episode will progress from bigger to bigger waves and explore how these killers are born.

The predators of the Underwater Universe have evolved to become our planet's most efficient killing machines. This episode explores the top five deadliest animals that no thinking human wants to tangle with, each more deadly than the next.
