Tides And The Ocean

Surfers, sailors, and anyone who loves the ocean will enjoy this visual exploration of the world's seas along its shores, including rip tides, swells, waves, and tsunamis. Tide is the vertical motion of water, something so subtle it is impossible to see with the naked eye. Inspired by his travels around the world's coastline in a camper van with his young family, William Thomson captures the cycles of the sea's movement, and intersperses his adventures surfing the waves and charting the tides. Throughout Tides and the Ocean are his graphic renderings of unusual tidal maps, as well as other forms of water movement, including rip, rapids, swell, stream, tide, wave, whirlpool, and tsunami. Tides and the Ocean explains how the tides surge when the moon and sun align with the earth; how ocean streams alternate direction every six hours (which is invaluable information for kayakers, paddle boarders, and fishermen); why skyscraper-sized tsunamis occur frequently in an Alaskan Bay; and the most deadly beach orientation for rip currents. Also emphasized throughout is the importance of keeping the world's oceans healthy and full of life. Published in time for beach travel, this large-format hardcover is ideal for anyone who knows and loves the sea, and who wants to understand, discover, surf, or sail it better.

In Tides: The Science and Spirit of the Ocean, writer, sailor, and surfer Jonathan White takes readers across the globe to discover the science and spirit of ocean tides. In the Arctic, White shimmies under the ice with an Inuit elder to hunt for mussels in the dark cavities left behind at low tide; in China, he races the Silver Dragon, a twenty-five-foot tidal bore that crashes eighty miles up the Qiantang River; in France, he interviews the monks that live in the tide-wrapped monastery of Mont Saint-Michel; in Chile and Scotland, he investigates the growth of tidal power generation; and in Panama and Venice, he delves into how the threat of sea level rise is changing human culture—the very old and very new. Tides combines lyrical prose, colorful adventure travel, and provocative scientific inquiry into the elemental, mysterious paradox that keeps our planet’s waters in constant motion. Photographs, scientific figures, line drawings, and sixteen color photos dramatically illustrate this engaging, expert tour of the tides.

A self-contained introduction to tides, explaining the origin of tidal constituents and their wave propagation in oceans and coastal seas.

A textbook that explains the causes of potentially devastating changes in sea level.

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.

In the first half of the nineteenth century, the British sought to master the physical properties of the oceans; in the second half, they lorded over large portions of the oceans’ outer rim. The dominance of Her Majesty’s navy was due in no small part to collaboration between the British Admiralty, the maritime community, and the scientific elite. Together, they transformed the vast emptiness of the ocean into an ordered and bounded grid. In the process, the modern scientist emerged. Science itself expanded from a limited and local undertaking receiving parsimonious state support to worldwide and relatively well financed research involving a hierarchy of practitioners. Analyzing the economic, political, social, and scientific changes on which the British sailed to power, Tides of History shows how the British Admiralty collaborated closely not only with scholars, such as William Whewell, but also with the maritime community —sailors, local tide table makers, dockyard officials, and harbormasters—in order to systematize knowledge of the world’s oceans, coasts, ports, and estuaries. As Michael S. Reidy points out, Britain’s security and prosperity as a maritime nation depended on its ability to maneuver through the oceans and dominate coasts and channels. The practice of science and the rise of the scientist became inextricably linked to the process of European expansion.

A history of the study of the tides over two millennia, from Ancient Greeks to present sophisticated space-age techniques.

The tide is the greatest synchronised movement of matter on our planet. Every drop of seawater takes part in tidal motion, driven by the gravitational pull of the moon and sun. At the coast, we see the tide as a twice-daily rise and fall of sea level that moves the edge of the sea up and down a beach or cliff-face. In some places, the tide is small but at others it can rise in a few hours by the height of a three storey building; it then has to be treated with great respect by those who live and work by the sea. In this Very Short Introduction David George Bowers and Emyr Martyn Roberts explore what we know about the tides. Blending clear explanations of well known tidal phenomena with recent insights in the deep ocean and coastal seas, Bowers and Roberts use examples from around the world, to tell the story of the tide, considering its nature and causes, its observation and prediction, and unusual tides and their relevance. They explore why tides have attracted the attention of some of the world's greatest scientists, from the initial challenge of explaining why there are two tides a day when the moon and sun pass overhead just once; a problem that was solved by Isaac Newton. In the 19th century, scientists unravelled the rhythms of the tide; good tidal predictions in the form of tide tables were then possible. The predictions were made on beautiful tide predicting machines constructed of brass and mahogany, some of which can still be seen in maritime museums. In the 20th century, the importance of tides as mixers of sea water became evident. As Bowers and Roberts explore, tidal mixing of the ocean is essential for maintaining its deep circulation, a key part of the climate-control system of our planet. In inshore waters, tidal mixing enhances biological productivity, influences sea temperature and turbidity and creates dramatic features such as maelstroms and tidal bores. In the 21st century, space probes are examining the effects of tidal processes on the moons of Jupiter and Saturn and the possibility of tidally-heated liquid oceans with their own ecosystems. Looking to the cutting edge of tidal research, Bowers and Roberts also consider how we can study the role of the tide in the geological and biological evolution of our own planet with innovative computer models.
