SHORTLISTED FOR THE MARITIME FOUNDATION AWARD FOR BEST BOOK 2024 A fascinating and original look at how the sea has defined Britain - and decided the course of its history - for thousands of years. Being an island nation is a core part of the British identity. An estimated two thirds of the world's population have never seen the sea, but in the UK that drops to under 10 per cent. Yet most people don't appreciate the impact our position on the edge of a continental shelf has had on our history, going back thousands of years. Our coast neither starts nor ends at the beach, and this eye-opening book takes a look beneath the surface to explore the forces of nature that have made Britain what it is. We experience some of the highest tides on the planet and we are battered with waves that have travelled halfway around the globe before they get here, but most of what we understand about our unique waters has only been discovered in living memory. In this fascinating guided tour of the fantastically varied British coastline, Professor David Bowers combines oceanography with maritime history, explaining tides, currents and waves in an accessible way whilst revealing how they have been responsible for both salvation (the Channel alone checked the Nazi advance in 1940) and disaster (such as the catastrophic 1953 flooding that led to the ingenious development of the Thames tidal barrier). He covers everything from how ocean swell waves were first recorded here in preparation for the D-Day landings, to how the first underwater light measurements paved the way to modern ocean satellite observation. This is a story 8,000 years in the making, ever since the country broke away from mainland Europe in the Mesolithic era, and in his insightful and irreverent telling of it Professor Bowers shows that the British Isles are defined by the sea, regardless of whether you look at them from land or water. With exclusive photos and specially commissioned illustrations, the book encourages you to visit all the places it explores, but when you stand on the beach or clifftop you will never think of Britain in quite the same way again.

David Bowers was born in Liverpool and grew up by the sea in North Wales. In his mid-twenties he decided to seek his fortune in the North Sea oil fields and, as a first step on the way to this goal, he trained to be an oceanographer. He never made a second step and the fortune didn't appear, but he did instead find a career researching into, and teaching about, the secrets of the ocean. This work has taken him to Australia, Africa and North America and on many scientific research cruises in the seas around the British Isles. David taught courses on oceanography for many years at Bangor University, from where he retired as an Emeritus Professor. He believes that science should be shared with the general public and that it is important that books make scientific discoveries accessible to all.
