Anybody who loves the sea will enjoy Dorling Kindersley's sumptuous new book 'Ocean: The World's Last Wilderness Revealed.' It costs £30 but it's worth every penny: it's a big book in every sense: more than 500 large format pages, covering every aspect of the world's oceans, from the surface to the floor.
Introduced by Fabien Cousteau, grandson of the legendary underwater explorer Jacques, this beautifully illustrated guide begins with an introduction to the water itself, the geology of the oceans, circulation and climate, and tides and waves.
The next section looks at Ocean Environments, starting with the coasts and seashore, then progressing through shallow seas to the open ocean and finally the polar regions.
Then there's Ocean Life, from bacteria to sea mammals, by way of seaweed, sponges, molluscs, arthropods, fish, reptiles, birds, and much more besides. And the final part of the book is a comprehensive Atlas of the Oceans.
The book underlines the oceans' power and importance to our planet - as the birthplace of life on Earth, a crucial element of our climate, and as a vital but increasingly fragile resource for humans.
Featuring the latest developments in ocean exploration and satellite maps of the entire sea floor, the book is packed with awe-inspiring images of ocean life. Dive in for a view of a world few of us have ever experienced.
This book would make a great Christmas present for any sailor - but if you buy it as a gift for someone else you're guaranteed to want to keep it for yourself!
