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.
