Digital underwater tips, hints and advice - the hottest emerging topic - from a recognised authority on the teaching of underwater photography

KILLER SHOCKWAVES: The Underwater Universe generates three types of deadly waves, each bigger and more destructive than the last: Rogue, Monster and Tsunami. Explore how these killers are born and what makes each unique. These battering rams of the underwater universe are the ocean s attempt to destroy us even on land, and they strike without warning.

PREDATORS OF THE DEEP: Bone crushing jaws, needle sharp teeth, venom so painful victims scream even after they re unconscious. The predators of the Underwater Universe have evolved to become our planet s most efficient killing machines. Discover the top five predators that prowl the ocean depths and how the top predator in the Underwater Universe might soon be replaced by another, far more menacing killer as ocean conditions change and traditional apex predators die out.

FATAL PRESSURE: 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. Is it possible for anything to survive the deepest place on Earth some seven miles down? Plunge through five ocean zones, each deadlier than the last, to uncover the mysteries of Fatal Pressure.

TIDES AND CURRENTS OF DEATH: The pull of the moon and spin of the earth generate mighty forces in the oceans that sweep relentlessly around the planet: tides and currents. Four of the Underwater Universe s most powerful tides and currents pose the greatest potential threat to mankind. How did an ocean current trigger the planet s most devastating mass extinction event? And could it happen again?

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 oceans 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, well depict the awesome cosmic and geological fluctuations that make the oceans deadly over time.

Ancient underwater cities can be found around the globe, but could these aquatic worlds be the ruins of unknown civilizations--or even proof of extraterrestrial visitations? The infamous tale of the long lost city of Atlantis may be a preserved memory of an ancient alien metropolis. Beneath Lake Titicaca in Peru, the ruins of recently discovered temples support local legends of an underwater UFO base. Ancient Indian texts, known as Sangams, describe sunken cities where aliens and humans intermingled thousands of years ago. Who could have built the 600-foot stepped stone structure off the coast of Japan--a site that may predate the Egyptian pyramids by thousands of years? Could evidence of ancient alien contact lie buried in Earth s deepest oceans?
