"A Beachcomber's Journal" is a photographic guide to a large collection of items, most of which have been found around the coastline in Monifieth, Angus, Scotland. It explores the history and origins of these finds as well as highlighting the environmental impact of marine pollution. It also provides a window into the past 100 years or so of what we ate and drank and reflects upon the changing tastes throughout the decades. The finds are from 2018 through to early 2022 and are grouped into types. It covers the effects on the marine environment in particular of the Covid 19 Pandemic from lockdown in early 2020 when the world became a much quieter place through to 2022 when freedoms were gradually restored and life began to be more "normal ". Once the most severe travel restrictions were lifted, there was a huge influx of visitors to what had previously been quiet beaches and a noticeable effect on the environment. This book raises awareness of what history literally lies beneath our feet as well as appreciating the natural beauty to be found on our beaches. We can all play our part in helping to protect the environment, both for marine life and for future generations.

Real-life applications are discussed and end of chapter problems help ensure full understanding. Students and practicing engineers will find this an invaluable resource for developing problem solving and design skills in a challenging ocean environment through the use of engineering mathematics.

"From New York Times bestselling author Susan Casey, an awe-inspiring portrait of the mysterious world beneath the waves, and the men and women who seek to uncover its secrets For all of human history, the deep ocean has been a source of wonder and terror, an unknown realm that evoked a singular, compelling question: What's down there? Unable to answer this for centuries, people believed the deep was a sinister realm of fiendish creatures and deadly peril. But now, cutting-edge technologies allow scientists and explorers to dive miles beneath the surface, and we are beginning to understand this strange and exotic underworld: A place of soaring mountains, smoldering volcanoes, and valleys 7,000 feet deeper than Everest is high, where tectonic plates collide and separate, and extraordinary life forms operate under different rules. Far from a dark void, the deep is a vibrant realm that's home to pink gelatinous predators and shimmering creatures a hundred feet long and ancient animals with glass skeletons and sharks that live for half a millennium-among countless other marvels. Susan Casey is our premiere chronicler of the aquatic world. For The Underworld she traversed the globe, joining scientists and explorers on dives to the deepest places on the planet, interviewing the marine geologists, marine biologists, and oceanographers who are searching for knowledge in this vast unseen realm. She takes us on a fascinating journey through the history of deep-sea exploration, from the myths and legends of the ancient world to storied shipwrecks we can now reach on the bottom, to the first intrepid bathysphere pilots, to the scientists who are just beginning to understand the mind-blowing complexity and ecological importance of the quadrillions of creatures who live in realms long thought to be devoid of life. Throughout this journey, she learned how vital the deep is to the future of the planet, and how urgent it is that we understand it in a time of increasing threats from climate change, industrial fishing, pollution, and the mining companies that are also exploring its depths. The Underworld is Susan Casey's most beautiful and thrilling book yet, a gorgeous evocation of the natural world and a powerful call to arms"--

Designing a wind turbine is an interdisciplinary process that requires an understanding of challenges for all parties involved. The authors deliver an effective and economic way to organize such a design by respecting all the challenges involved. The book provides such insight by utilizing specific examples of existing modern designs. Detailed descriptions and explanations are given for those components of the wind turbine that are normally developed by the so-called original equipment manufacturers (OEM) of a particular type. The OEM needs to have full knowledge of the complete system that consists of all parts being rotor blades, nacelle, drive train, tower, and foundation including the dynamic properties and the response to the controller action. This full knowledge is called system competence. For a wind turbine the drive train is the most important system. It consists of many components like shafts, bearings, gearbox, and generator for a wind turbine with a gear box; in systems without a gearbox a large generator has to be integrated into the drive train.

The Discovery of the calcareous Ioffe Drift in the SW Atlantic in 2010 opens new perspectives in the contourite theory. Although demonstrating similar behavior relative to bottom water dynamics, rather rare and poorly studied calcareous contourites differ from their terrigenous analogs in origin, grain-size distribution, chemical and mineral composition of sedimentary particles. The detailed multidisciplinary study of the Ioffe Drift produces new knowledge on biogenic contourites deposited in pelagic realm, in conditions of low biological productivity and terrigenous material supply, under the influence of the Antarctic Bottom Water flow from the Vema Channel. The major intervals of prevailing erosion are inferred on the drift from 2.51/2.59 to 1.9 Ma and from 1.6 to 0.81 Ma thus indicating strong paleoceanographic changes most likely associated with the reorganization of deep-sea circulation and increased bottom water production in the Southern Ocean during the Early Pleistocene and,in particular, around the Mid-Pleistocene Transition.

Drawing on the expertise of marine researchers from both the natural and social sciences, this book examines how we, as both scientists and societies, can return to a sustainable co-existence with the ocean and use the tools of transdisciplinarity to bring together the diverse forms of knowledge needed to achieve this important task.

This unique textbook presents an introduction to the interdisciplinary field of marine studies, exploring the dynamic relationship between people and the marine environment.

The dramatic and action-packed story of the last mysterious place on earth?the world's seafloor?and the deep-sea divers, ocean mappers, marine biologists, entrepreneurs, and adventurers involved in the historic push to chart it, as well as the opportunities, challenges, and perils this exploration holds now and for the future.Five oceans?the Atlantic, the Pacific, the Indian, the Arctic, and the Southern?cover approximately 70 percent of the earth. Yet we know little about what lies beneath them. By the early 2020s, less than twenty-five percent of the ocean's floor has been charted, most close to shorelines, and over three quarters of the ocean lies in in what is called the Deep Sea, depths below a thousand meters. Now, the race is on to completely map the ocean's floor by 2030?an epic project involving scientists, investors, militaries, and private explorers who are cooperating and competing to get an accurate reading of this vast terrain and understand its contours and environment. In The Deepest Map, Laura Trethewey documents this race to the bottom, following global efforts around the world, from crowdsourcing to advances in technology, recent scientific discoveries to tales of dangerous dives in untested and costly submersibles. The lure of ocean exploration has attracted many, including the likes of James Cameron, Richard Branson, Ray Dalio, and Eric Schmidt. The Deepest Map follows a cast of intriguing characters, from early mappers such as Marie Tharp, a woman working in the male-dominated fields of oceanography and geology whose discoveries have added significantly to our knowledge; Victor Vescovo, a man obsessed with reaching the deepest depths of each of the five oceans, and his young, brilliant, and fearless mapper Cassie Bongiovanni; and the diverse entrepreneurs looking to explore and exploit this uncharted territory and its resources.In The Deepest Map, ocean discovery converges with humanity's origin story; in mapping the ocean floor, scientists are actively tracing our roots back to the most inhospitable places on earth where life began?and flourished. But for every conservationist looking to protect the seafloor, there are others who see its commercial potential. Will a new map exacerbate pollution and the degradation of this natural resource? How will the race remake political power structures in years to come? Trethewey probes these questions as countries and conglomerates wrestle over the riches that may lie at the bottom of the sea.The future of humanity depends on our ability to protect this vast, precious, and often ignored resource. A true tale of science, nature, technology, and an extreme outdoor adventure The Deepest Map illuminates why we love?and fear?the earth's final frontier and is a crucial addition to the increasingly urgent conversation about climate change.

This book is a unique and authoritative review of chemical fronts in the ocean world.

Oil and natural gas represent more than 50 percent of the worldwide energy supply, with high energy demand driven by population growth and improving standards of living. Despite significant progress in reducing the amount of oil in the sea from consumption, exploration, transportation, and production, risks remain. This report, the fourth in a series, documents the current state-of-knowledge on inputs, fates and effects of oil in the sea, reflecting almost 20 additional years of research, including long-term effects from spills such as the Exxon Valdez and a decade-long boom in oil spill science research following the Deepwater Horizon oil spill. The report finds that land-based sources of oil are the biggest input of oil to the sea, far outweighing other sources, and it also notes that the effects of chronic inputs on the marine environment, such as land-based runoff, are very different than that from an acute input, such as a spill. Steps to prevent chronic land-based oil inputs include reducing gasoline vehicle usage, improving fuel efficiency, increasing usage of electric vehicles, replacing older vehicles. The report identifies research gaps and provides specific recommendations aimed at preventing future accidental spills and ensuring oil spill responders are equipped with the best response tools and information to limit oil's impact on the marine environment.

The Ocean Sunfishes: Evolution, Biology and Conservation is the first book to gather into one comprehensive volume our fundamental knowledge of the world-record holding, charismatic ocean behemoths in the family Molidae.

This book presents state-of-the-art perspectives on the Blue Economy. It applies important geographical and sustainability transitions perspectives and underscores how Blue Economy dynamics are situated in regional contexts and shaped by the people who live there.The book highlights the Blue Economy concept as a potential driver of regionally sensitive, ecologically embedded, and community-focused sustainability. The scope for Blue Economy to form a core "cog" in our low-carbon future is obvious, from the potential for renewable energy production and coastal resilience building to possibilities for sustainable food production and the delivery of economic opportunities for peripheral communities. However, fundamental questions remain on how to meaningfully deliver these promises, such as how to avoid embedding a model of damaging extractivism, as per the terrestrial economy, and how to deliver on the key social sustainability principles of human well-being, equity, and justice when planning and developing blue economies. As the UN Decade of Ocean Science for Sustainable Development opens, this book provides a timely reminder of the richness, diversity, and potential of coastal and marine spaces. It advances geographical and transdisciplinary understandings of the Blue Economy and sets a baseline for continued scholarly engagement with the Blue Economy from a variety of perspectives.This timely contribution will be of interest to policy makers, academics, industry leaders, decision makers, and stakeholders working in or connected to the Blue Economy Sphere and working in the fields of Economic Geography, Regional Development, Public Policy and Planning, Environmental Studies, and Coastal Zone Management.
