Big Pacific The Pacific Ocean covers one third of the Earth's surface. It is larger than all Earth's land combined, holds half of our world's water, and hides the deepest place on our planet. It is a place where huge and iconic, rare and dazzling creatures live - and where creatures yet to be discovered lurk. The Pacific sees the most violent storms, creates the most powerful waves, and is powered by the strongest currents. It boasts the largest coral reefs and the richest kelp forests. It's submarine landscape plummets from sea grass prairies to the ultimate abyss, and it's tropical seamounts starkly contrast with it's massive ice floes.
