The hydrodynamic forces produced by breaking waves make the rocky intertidal zone one of the most physical stressful environments on Earth. Although the classical in-line hydrodynamic forces are well studied and characterized, an undescribed force -- known as the impingement force -- may be the largest hydrodynamic force in the intertidal zone. Impingement is characterized by a sharp, transient spike in force at the instant of wave arrival, and very few measurements of it exist. I measured impingement in the laboratory, using a gravity-driven water cannon to simulate waves and tested which variables affect impingement magnitude. I show that impingement is likely drag, rather than an undescribed hydrodynamic force; it likely occurs due to brief increases in flow velocity at the front of a wave. To assess the frequency and magnitudes of impingement events in the field, I built a force transducer to record high-frequency forces in the intertidal zone. Impingement events occur in 2-7% of waves in the field, but surprisingly, the average magnitude of impingement events is lower than the average maximum force produced by all recorded waves in this study. This suggests that impingement is not the largest hydrodynamic risk to organisms, and future work measuring flows in the intertidal zone should focus on identifying large transient forces regardless of where they occur in a wave. Using these measurements, I explore the likely effects of brief forces on intertidal organisms in two ways: first, I model a limpet as a mechanical spring-mass-damper system and show that its foot has the capacity to reduce the effective force on the animal. I also predict dislodgment rates of three species of gastropod using the maximum forces recorded in my field study. At my site, snails are very susceptible to wave-induced dislodgment. This dissertation illustrates the necessity of recording high-frequency flows when studying intertidal hydrodynamics.

"This is the book I have been waiting for! Written by experts in each field, this Encyclopedia provides a wealth of information not only about the tidepool and shore life but also the oceanography associated with these habitats. This will be a major reference guide for years to come."--Dr. Nigella Hillgarth, Executive Director, Birch Aquarium at Scripps, Scripps Institution of Oceanography "The "Encyclopedia of Tidepools and Rocky Shores" covers much more than one might guess. It ranges from oceanography, to physiology, biomechanics, and conservation science, along with the expected treatment of the diverse groups of organisms that live in those habitats. The coverage of each topic is kept short and comprehensible to almost everyone, from high schools to colleges, and certainly to the general public interested in learning more about this fascinating part of our natural world. Best of all, the editors have managed to get some of the best scientists in the world, the absolute experts in their fields, to write the articles. The relatively short length of each entry also makes this book an ideal source for assigned readings to accompany marine biology, ecology, or oceanography classes, laboratories and field trips. It will be much appreciated by teachers and students."--Ken Sebens, Director of the Friday Harbor Marine Laboratories, University of Washington "The place where vast oceans meet the land is wondrous, complex and fascinating. Visitors from research scientists to toddlers have explored these ecosystems--one of nature's most popular theme parks. Anyone who has spent time amongst the sea stars, crabs and kelp departs full of unanswered questions. Now these questions can beanswered by dipping into the "Encyclopedia of Tidepools and Rocky Shores," The editors and contributors to this reference have created a new standard that will be an immediate classic."--Leon Panetta, Director, The Leon & Sylvia Panetta Institute for Public Policy "This volume is a wonderful introduction to the hidden and fascinating world of rocky tidepools. Grab a copy and head out with your kids or students for an outdoor experience that's sure to get them hooked. From remarkable adaptations of marine algae to weird animal life histories, tidepools hold amazing stories to tell. They deserve our interest--and our care--as part of earth's natural systems that sustain us all."--Julie Packard, Executive Director, Monterey Bay Aquarium "Tide pool lovers the world around will satisfy their curiosity, uncover new gems of insight and renew their wonder of nature at lands' end in this authoritative, fascinating and insightful compilation. Revealed within are the secrets of rocky shores and tide pools--that most dynamic of interfaces between the land and the sea, that treasure chest of rich biodiversity and keen insight, that world where science, literature, beauty and stewardship combine to form the now that integrates the past and tempts the future."--Jane Lubchenco, Wayne and Gladys Valley Professor of Marine Biology, Oregon State University

The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

Intertidal Deposits: River Mouths, Tidal Flats, and Coastal Lagoons combines the authors personal and professional experience with the mass of available literature to present a cohesive overview of intertidal deposits and the widely diverse conditions of their formation worldwide. This includes the strong influence of water movements, climate, sediment particle characteristics, vegetation, fauna, and man. Intertidal areas are important for many reasons both scientifically and economically and recently, a growing concern for conservation of these fragile regions strives to preserve and protect their natural balance. This book, written by an international expert in the field, concentrates on the more important intertidal areas distinguished by size and morphology, tidal range, the degree and type of vegetational cover, the amount and type of benthic fauna, the extent of human exploitation, and the degree of previous study.

The aim of this open access book is to review and analyse the goods and services of bivalve shellfish. How they are defined, what determines the ecological functions that are the basis for the goods and services, what controversies in the use of goods and services exist, and what is needed for sustainable exploitation of bivalves from the perspective of the various stakeholders. The book is focused on the goods and services, and not on impacts of shellfish aquaculture on the benthic environment, or on threats like biotoxins; neither is it a shellfish culture handbook although it can be used in evaluating shellfish culture. The reviews and analysis are based on case studies that exemplify the concept, and show the strengths and weaknesses of the current applications. The multi-authored reviews cover ecological, economic and social aspects of bivalve goods and services. The book provides new insights for scientists, students, shellfish producers, policy advisors, nature conservationists and decision makers. This book is open access under the CC BY license.
