Jonathan traveled the world researching and writing this book – and he’s got amazing stories to tell!


Jonathan enjoys speaking to audiences of all kinds. He has given talks and keynote presentations at museums, aquariums, yacht clubs, government institutions, book clubs, writing conferences, grade schools, bookstores, and universities. Examples include the Seattle Center for Wooden Boats, the SeaDoc Society, the Northwest Straits Marine Conservation Initiative, The Evergreen State College, Orcas Island High School, and the Padilla Bay Marine Reserve. Sailors, surfers, fishers, divers, kayakers, and beachcombers all know the importance of time and tide, but most people don’t know how complex and poetic the phenomenon is. How do you explain, for example, that the tide is twenty-eight feet on the west side of Panama and only ten inches on the east side? Or that some places see one tide a day, while others see two or even six tides a day? What’s a double high tide, or a double low tide? These are among the topics Jonathan has fun describing, illustrated with photographs and stories — and always in simple, accessible language that emphasizes the tide’s mystery and beauty.


“You’d think an audience full of sailors, kayakers, surfers, fishermen/women and people who live at the coast and walk the beach daily would know about tides. We all learned how much we didn’t know. Jonathan presented a fascinating and informative slide show, talk, and book reading for our Manzanita Writers’ Series to a larger than average crowd. The Q&A could have gone on all night. We’ve been getting kudos about his presentation all week since. Jonathan’s passion for the subject and his depth of research is evident. The book really manages to combine the science and the stories, beliefs, and effects of tides around the world, in an engaging “non-dry” way that keeps you reading.”
– Kathie Hightower, co-founder of the Manzanita Writers’ Series

“Jonathan is a consummate story-teller. It becomes apparent that he lives and breathes ‘Tides’, and carries his fascinating experiences from Europe to China, from northeastern Canada to the tropics as an essential part of his soul. The result is that listeners are emotionally transported with Jonathan to these amazing locations; you feel the excitement and reverence for the combined power of water, earth and moon, the same passion for exploration and understanding. And you’ll have fun, sharing laughter, smiles and amazement-and likely appreciation that Jonathan put himself in dangerous places so you can see and feel what he saw and felt…without personal risk.”
– Jeff Renner, Chief Meteorologist, King-TV, and host of Seattle Aquarium’s “Sound Conversations.”

“Jonathan took the San Francisco Bay Area by storm. An interview on PBS radio the day before, sold out Lecture audience, and outstanding program. The evening was just the right balance between science and adventure, with stunning visuals and interesting stories. His book, and this lecture, received rave reviews.”
– Brian Baird, Director, Coast and Ocean Program- The Bay Institute/Aquarium of the Bay, San Francisco, CA
