The Mysterious Ocean

by David Meyer

Dr. Jon Copley provides an illuminating tour through the sunlit surfaces and Stygian darkness of the world’s oceans.

Ocean explorers have been studying the deep since the 1800s, yet much of what’s below the surface remains a mystery. Dr. Jon Copley – scientific adviser for the BBC TV series, Blue Planet II – outlines historical, biological and environmental facts and provides glimpses of the ocean’s wonder. His short but surprisingly comprehensive book will delight science nerds and armchair adventurers alike.

Six Miles Deep

The deepest part of the ocean is the Pacific’s Mariana Trench, at 10,916 meters – more than six miles – deep. On average, the Earth’s oceans are 3,400 meters deep. Much of the ocean’s floor remains a mystery.
