From the New York Times-bestselling author of The Secret World of Weather and The Lost Art of Reading Nature’s Signs, learn to tap into nature and notice the hidden clues all around you Before GPS, before the compass, and even before cartography, humankind was navigating. Now this singular guide helps us rediscover what our ancestors long understood—that a windswept tree, the depth of a puddle, or a trill of birdsong can help us find our way, if we know what to look and listen for. Adventurer and navigation expert Tristan Gooley unlocks the directional clues hidden in the sun, moon, stars, clouds, weather patterns, lengthening shadows, changing tides, plant growth, and the habits of wildlife. Rich with navigational anecdotes collected across ages, continents, and cultures, The Natural Navigator will help keep you on course and open your eyes to the wonders, large and small, of the natural world.
From Cnut to D-Day: the history and science of the unceasing tide explored for the first time. Half of the world's population lives in coastal regions lapped by tidal waters. Yet how little most of us know about the tide. Our ability to predict and understand the tide depends on centuries of science, from the observations of Aristotle and the theories of Newton to today's supercomputer calculations. This story is punctuated here by notable tidal episodes in history, from Caesar's thwarted invasion of Britain to the catastrophic flooding of Venice, and interwoven with a rich folklore that continues to inspire art and literature today. With Aldersey-Williams as our guide to the most feared and celebrated tidal features on the planet, from the original maelstrøm in Scandinavia to the world's highest tides in Nova Scotia to the crumbling coast of East Anglia, the importance of the tide, and the way it has shaped - and will continue to shape - our civilization, becomes startlingly clear.
Contains daily predicted times of slack water and predicted times and velocities of maximum current.
The tide is important to Earth's climate, the biological productivity of our seas, and our hunt for renewable energy sources. It is also thought to have played a role in the evolution of life on Earth. This book explains the nature and cause of the tide, its observation and prediction, unusual tides, and their relevance to us.
Four seasons of immersion in New England’s Great Marsh “Like Wendell Berry and Rachel Carson, Hanlon is a true poet-ecologist, sharing in exquisitely resonant prose her patient observations of nature’s most intimate details. As she and her husband, through summer and snow, swim their local creeks and estuaries, we marvel at the timeless yet fragile terrain of both marshlands and marriage. This is the book to awaken all of us, right now, to how our coastline is changing and what it means for our future.” —Julia Glass, author of Three Junes and A House Among the Trees The Great Marsh is the largest continuous stretch of salt marsh in New England, extending from Cape Ann to New Hampshire. Patricia Hanlon and her husband built their home and raised their children alongside it. But it is not until the children are grown that they begin to swim the tidal estuary daily. Immersing herself, she experiences, with all her senses in all seasons, the vigor of a place where the two ecosystems of fresh and salt water mix, merge, and create new life. In Swimming to the Top of the Tide, Hanlon lyrically charts her explorations, at once intimate and scientific. Noting the disruptions caused by human intervention, she bears witness to the vitality of the watersheds, their essential role in the natural world, and the responsibility of those who love them to contribute to their sustainability. Patricia Hanlon is a visual artist who paints the beautiful ecosystem of New England’s Great Marsh and is involved in the watershed organizations of Greater Boston. Swimming to the Top of the Tide is her first book.
Engineers’ dreams and fossil energy replacement schemes can come true. Man has been tapping the energy of the sea to provide power for his industries for centuries. Tidal energy combined with that of waves and marine winds rank among those most successfully put the work. Large scale plants are capital intensive but smaller ones, particularly built in China, have proven profitable. Since the initiation of the St Malo project in France, similar projects have gone into active service where methods have been devised to cut down on costs, new types of turbines developed and cost competitiveness considerably improved. Tidal power has enormous potential. The book reviews recent progress in extracting power from the ocean, surveys the history of tidal power harnessing and updates a prior publication by the author.
