In Part I (Schwiderski, 1978a) of this report, a unique hydrodynamical interpolation technique was introduced, extensively tested, and evaluated in order to compute partial global ocean tides in great detail and with a high degree of accuracy. This novel method has been applied to construct the diurnal principal solar (P1) ocean tide with a relative accuracy of better than 5 cm anywhere in the open oceans. The resulting tidal amplitudes and phases are tabulated on a 1 deg X 1 deg grid system in an atlas of 42 deg X 71 deg overlapping charts covering the whole oceanic globe. A corresponding atlas of global corange and cotidal maps is included to provide the reader with a quick general overview of the major tidal phenomena. The specifying hydrodynamical parameters of the model are listed along with quoted sources of empirical tide data, and significant tidal features are explained and discussed. As expected, since the periods of the diurnal tides P1 (24.07h) and K1 (23.93 h) differ by only 0.14 h, these two tides resemble very closely each other (compare Part IV). Significant differences occur only in regions of rapid tidal variations. Of course, P1 resembles also the diurnal 01 tide but to a visibly lesser degree (see Part V). (Author).

In Part I (Schwiderski, 1978a) of this report, a unique hydrodynamical interpolation technique was introduced, extensively tested, and evaluated in order to compute partial global ocean tides in great detail and with a high degree of accuracy. This novel method has been applied to construct the diurnal elliptical lunar (Q1) ocean tide with a relative accuracy of better than 5 cm anywhere in the open oceans. The resulting tidal amplitudes and phases are tabulated on a 1 x 1 deg grid system in an atlas of 42 x 71 deg overlapping charts covering the whole oceanic globe. A corresponding atlas of global corange and cotidal maps is included to provide the reader with a quick general overview of the major tidal phenomena. The specifying hydrodynamical parameters of the model are listed along with quoted sources of empirical tide data, and significant tidal features are explained and discussed. The diurnal Q1 tide resembles all other computed diurnal tides K1, O1, and P1 (see Part IV, V, and VII). Qualitative similarities exist also between the diurnal and semidiurnal species M2, S2, N2, and K2 (see Parts II, III, VI, and VIII). (Author).

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.
