A Science Friday Best Science Book of the Year A Kirkus Reviews Best Nonfiction Book of the Year A Library Journal Best Science and Technology Book of the Year A Tampa Bay Times Best Book of the Year A stunning history of seashells and the animals that make them that "will have you marveling at nature…Barnett’s account remarkably spirals out, appropriately, to become a much larger story about the sea, about global history and about environmental crises and preservation" (John Williams, New York Times Book Review). Seashells have been the most coveted and collected of nature’s creations since the dawn of humanity. They were money before coins, jewelry before gems, art before canvas. In The Sound of the Sea, acclaimed environmental author Cynthia Barnett blends cultural history and science to trace our long love affair with seashells and the hidden lives of the mollusks that make them. Spiraling out from the great cities of shell that once rose in North America to the warming waters of the Maldives and the slave castles of Ghana, Barnett has created an unforgettable history of our world through an examination of the unassuming seashell. She begins with their childhood wonder, unwinds surprising histories like the origin of Shell Oil as a family business importing exotic shells, and charts what shells and the soft animals that build them are telling scientists about our warming, acidifying seas. From the eerie calls of early shell trumpets to the evolutionary miracle of spines and spires and the modern science of carbon capture inspired by shell, Barnett circles to her central point of listening to nature’s wisdom—and acting on what seashells have to say about taking care of each other and our world.

For the 119 species of marine mammals, as well as for some other aquatic animals, sound is the primary means of learning about the environment and of communicating, navigating, and foraging. The possibility that human-generated noise could harm marine mammals or significantly interfere with their normal activities is an issue of increasing concern. Noise and its potential impacts have been regulated since the passage of the Marine Mammal Protection Act of 1972. Public awareness of the issue escalated in 1990s when researchers began using high-intensity sound to measure ocean climate changes. More recently, the stranding of beaked whales in proximity to Navy sonar use has again put the issue in the spotlight. Ocean Noise and Marine Mammals reviews sources of noise in the ocean environment, what is known of the responses of marine mammals to acoustic disturbance, and what models exist for describing ocean noise and marine mammal responses. Recommendations are made for future data gathering efforts, studies of marine mammal behavior and physiology, and modeling efforts necessary to determine what the long- and short-term impacts of ocean noise on marine mammals.

In Horizon, Sea, Sound: Caribbean and African Women’s Cultural Critiques of Nation, Andrea Davis imagines new reciprocal relationships beyond the competitive forms of belonging suggested by the nation-state. The book employs the tropes of horizon, sea, and sound as a critique of nation-state discourses and formations, including multicultural citizenship, racial capitalism, settler colonialism, and the hierarchical nuclear family. Drawing on Tina Campt’s discussion of Black feminist futurity, Davis offers the concept future now, which is both central to Black freedom and a joint social justice project that rejects existing structures of white supremacy. Calling for new affiliations of community among Black, Indigenous, and other racialized women, and offering new reflections on the relationship between the Caribbean and Canada, she articulates a diaspora poetics that privileges our shared humanity. In advancing these claims, Davis turns to the expressive cultures (novels, poetry, theater, and music) of Caribbean and African women artists in Canada, including work by Dionne Brand, M. NourbeSe Philip, Esi Edugyan, Ramabai Espinet, Nalo Hopkinson, Amai Kuda, and Djanet Sears. Davis considers the ways in which the diasporic characters these artists create redraw the boundaries of their horizons, invoke the fluid histories of the Caribbean Sea to overcome the brutalization of plantation histories, use sound to enter and reenter archives, and shapeshift to survive in the face of conquest. The book will interest readers of literary and cultural studies, critical race theories, and Black diasporic studies.

This moving tale explores the relationship between a young boy, Samuel Sullivan, and his mother. Samuel is remembering the precious times he spent with his mother before she became ill and went away. With the love and support of his grandparents, Samuel gradually starts to understand and little by little realises that although his mother is gone, she is with him always.Jacqueline Harvey wrote this story one evening after an afternoon fishing trip to South Golden Beach, north of Byron Bay. A young boy about nine years old arrived with his fishing rod in hand accompanied by his very pregnant mother, and the pair evoked in her feelings of the incredible, often unspoken love, between a parent and child. Jacqueline began to think about a young boy she had known who had lost his mother at a young age, and the poignancy of his devastation and ultimate survival.Samuel s anger, grief and eventual acceptance of his mother s death are brilliantly depicted in Warren Crossett s beautiful illustrations.

The developments in the field of ocean acoustics over recent years make this book an important reference for specialists in acoustics, oceanography, marine biology, and related fields. Fundamentals of Acoustical Oceanography also encourages a new generation of scientists, engineers, and entrepreneurs to apply the modern methods of acoustical physics to probe the unknown sea. The book is an authoritative, modern text with examples and exercises. It contains techniques to solve the direct problems, solutions of inverse problems, and an extensive bibliography from the earliest use of sound in the sea to present references. Written by internationally recognized scientists, the book provides background to measure ocean parameters and processes, find life and objects in the sea, communicate underwater, and survey the boundaries of the sea. Fundamentals of Acoustical Oceanography explains principles of underwater sound propagation, and describes how both actively probing sonars and passively listening hydrophones can reveal what the eye cannot see over vast ranges of the turbid ocean. This book demonstrates how to use acoustical remote sensing, variations in sound transmission, in situ acoustical measurements, and computer and laboratory models to identify the physical and biological parameters and processes in the sea. * Offers an integrated, modern approach to passive and active underwater acoustics * Contains many examples of laboratory scale models of ocean-acoustic environments, as well as descriptions of experiments at sea * Covers remote sensing of marine life and the seafloor * Includes signal processing of ocean sounds, physical and biological noises at sea, and inversions * resents sound sources, receivers, and calibration * Explains high intensities; explosive waves, parametric sources, cavitation, shock waves, and streaming * Covers microbubbles from breaking waves, rainfall, dispersion, and attenuation * Describes sound propagation along ray paths and caustics * Presents sound transmissions and normal mode methods in ocean waveguides

All life — whether on land or in the sea — depends on the oceans for two things: • Oxygen. Most of Earth’s oxygen is produced by phytoplankton in the sea. These humble, one-celled organisms, rather than the spectacular rain forests, are the true lungs of the planet. • Climate control. Our climate is regulated by the ocean’s currents, winds, and water-cycle activity. Sea Sick is the first book to examine the current state of the world’s oceans — the great unexamined ecological crisis of the planet — and the fact that we are altering everything about them; temperature, salinity, acidity, ice cover, volume, circulation, and, of course, the life within them. Alanna Mitchell joins the crews of leading scientists in nine of the global ocean’s hotspots to see firsthand what is really happening around the world. Whether it’s the impact of coral reef bleaching, the puzzle of the oxygen-less dead zones such as the one in the Gulf of Mexico, or the shocking implications of the changing Ph balance of the sea, Mitchell explains the science behind the story to create an engaging, accessible yet authoritative account.

This Technical Report presents the outcome of a Working Group that was established to determine broadly applicable sound exposure guidelines for fishes and sea turtles. After consideration of the diversity of fish and sea turtles, guidelines were developed for broad groups of animals, defined by the way they detect sound. Different sound sources were considered in terms of their acoustic characteristics and appropriate metrics defined for measurement of the received levels. The resultant sound exposure guidelines are presented in a set of tables. In some cases numerical guidelines are provided, expressed in appropriate metrics. When there were insufficient data to support numerical values, the relative likelihood of effects occurring was evaluated, although the actual likelihood of effects depends on the received level. These sound exposure guidelines, which are based on the best scientific information at the time of writing, should be treated as interim. The expectation is that with more research the guidelines can be refined and more cells in the tables completed. Recommendations are put forward defining the research requirements of highest priority for extending these interim exposure guidelines.
