Ebb and Flow: Tides and Life on Our Once and Future Planet (Paperback)

Susan Lundy of the Gulf Islands Driftwood [Nov. 28, 2007 writes: "Koppel successfully walks the line between presenting complex material in a readable way without 'dumbing down' the content. Each chapter opens with an anecdote drawn mostly from Koppel's many experiences on the sea. The stories segue into the chapters, giving life to the science, reiterating the role tides play in everyday existence and putting the reader right into the scene."

Mark Lardas of the Galveston (Texas) Daily News [Oct. 28, 2007 writes: "Despite the formidable complexity of the science of tides, Koppel packages his explanations approachably. You do not need to be a rocket science to understand him, yet everyone-even scientists-will find this book absorbing..a fascinating mix of science, history and memoir, which is completely entertaining."

Cherie Thiessen of Canada's book industry magazine, Quill & Quire [Dec. 28, 2007 writes: "[The book has been in the making for more than 20 years..It's been worth the wait. Koppel, who has been praised for his ability to explain complicated science to the average reader, isdoing it again. Beginning with the earliest human attempts to explain the phenomenon of the oceans' movements, carrying on through to Isaac Newton's breakthrough in tidal theory in the 17th century, and on to the adventures of later European explorers as they learned firsthand that all tides are not created equal, the book mixes fact with personal experiences and observations."

Tom Hawthorn, of the Toronto Globe and Mail [Jan. 2, 2008], writes that "Koppel never lost the curiosity he held as a boy for a natural order that lifted an island’s dock as much as four metres twice a day, and a lifetime's travel has led to an exploration of the phenomena...[He] finds the rise and fall of empires mirrored in the sea's ebb and flow, incorporating Julius Caesar and Alexander the Great in his captivating look at tides. He examines the complex science of tides and explores their possible future as an energy source...A veteran magazine writer, Mr. Koppel knows how to tell a story."
