Deep time is the timescale of the geological events that have shaped our planet. Whilst so immense as to challenge human understanding, its evidence is nonetheless visible all around us. Through explanations of the latest research and over 200 fascinating images, Deep Time explores this evidence, from the visible layers in ancient rock to the hiss of static on the radio, and from fossilized shark's teeth to underwater forests. These relics of ancient epochs, many of which we can see and touch today, connect our present to the distant past and answer broader questions about our place in the timeline of the Earth. Charting 4.5 billion years of geological history, this is the story of our world, from its birth to the dawn of civilization.

What lies beneath the surface of the ocean has mystified humankind for millennia. We have explored more of the surface of the Moon than we have of the deep sea. From vampire squid to giant spider crabs, and from hydrothermal vents to bioluminescence, its watery depths are both fascinating and terrifying. Deep Water explores, through spectacular images and expert text, how this unique habitat came into being, what lives there and why, how it has evolved and what the future will bring for this dark and mysterious environment.
