The image most of us have of whalers includes harpoons and intentional trauma. Yet eating commercially caught seafood leads to whales' entanglement and slow death in rope and nets, and the global shipping routes that bring us readily available goods often lead to death by collision. We-all of us-are whalers, marine scientist and veterinarian Michael J. Moore contends. But we do not have to be. Drawing on over forty years of fieldwork with humpback, pilot, fin, and in particular, North Atlantic right whales-a species whose population has declined more than twenty percent since 2017-Moore takes us with him as he performs whale necropsies on animals stranded on beaches, in his independent research alongside whalers using explosive harpoons, and as he tracks injured whales to deliver sedatives. The whales' plight is a complex, confounding, and disturbing one. We learn of existing but poorly enforced conservation laws and of perennial (and often failed) efforts to balance the push for fisheries profit versus the protection of endangered species caught by accident. But despite these challenges, Moore's tale is an optimistic one. He shows us how technologies for rope-less fishing and the acoustic tracking of whale migrations make a dramatic difference. And he looks ahead with hope as our growing understanding of these extraordinary creatures fuels an ever-stronger drive for change.

Longlisted for the Wainwright Prize Shortlisted for the Richard Jeffries Award The story of one woman's passion for glaciers As one of the world's leading glaciologists, Professor Jemma Wadham has devoted her career to the glaciers that cover one-tenth of the Earth's land surface. Today, however, these 'ice rivers' are in peril. High up in the Alps, Andes and Himalaya, once-indomitable glaciers are retreating; in Antarctica, meanwhile, thinning ice sheets are releasing meltwater to sensitive marine foodwebs, and may be unlocking vast quantities of methane stored deep beneath them. The potential consequences for humanity are almost unfathomable. Jemma's first encounter with a glacier, as a student, sparked her love of these icy landscapes. There is nowhere on Earth she feels more alive. Whether abseiling down crevasses, skidooing across frozen fjords, exploring ice caverns, or dodging polar bears - for a glaciologist, it's all in a day's work. Prompted by an illness that took her to the brink of death and back, in Ice Rivers Jemma recalls twenty-five years of expeditions around the globe, revealing why the glaciers mean so much to her - and what they should mean to us. As she guides us from the Alps to the Andes, the importance of the ice to crucial ecosystems and human livelihoods becomes clear - our lives are entwined with these coldest places on the planet. This is a memoir like no other: an eye-witness account by a top scientist at the frontline of the climate crisis, and an impassioned love letter to the glaciers that are her obsession.

Die Anregung, dies Buch zu schreihen, trat an dem Abend an mich heran, an dem ich zum ersten Male versuchte, die biologischen Ergebnisse der "Meteor"-Expedition in groBen Umrissen einem wissenschaftlichen Kreise vorzutragen. Die Erinnerungen jahrelanger Seefahrt, auf der langsam eine groBe Gesamtanschauung vom Leben des Weltmeers in mir herangewachsen war, verbanden sich in dieser Stunde mit Erinnerungen weit zuriickliegender Jahre: Ich dachte an die Zeit, da ich einen der groBten deutschen Meister versUind lidher Wissenschaft, Alexander von Humboldt, zum ersten Male las. Ich habe vielleicht nie wieder so stark wie damals reine Wissenschaft als in das Leben eingreifende Macht ernpfunden. Spater, inmitten der Oberfiille von Wissenschaft aller Art, ist mir dies Gefiihl oft verlorengegangen. Das Wesentliche, das wirklich Wissenswerte wird heute von so viel weniger Wichtigern, selbst Wertlosem iiberwuchert, dill. man leicht den Blick fiir die grofien Ziige des Ganzen verliert. Die Wissenschaft wachst in vielen ihrer Teile wie ein unbe schnittener Baurn, an dem die fruchtbaren Zweige unter dem Wuchem der unfruchtbaren leiden. Ich habe mich daher viel urn die Frage bemiiht: Was ist wissenswert? Und warum ist etwas wissenswert? - Gewifi vieles deswegen, weil es Nutzen bringt. Aber den Wert der Wissenschaft an der praktischen Verwertharkeit ihrer Er gebnisse messen oder gar die "angewandte" Wissenschaft hoher als die "reine," zweckunbewuBte bewerten, das hieBe, v Apfel und Trauben nach ihrem Nahrwert sehatzen wollen."

Colin Speedie's new book takes us from swashbuckling hunts of giant sharks by reckless individuals with makeshift harpoons, through an age of mass slaughter, to the author's personal shark-tracking adventures in the name of conservation.There are few marine creatures as spectacular as the Basking Shark. At up to 11 metres in length and seven tonnes in weight, this colossal, plankton-feeding fish is one of the largest in the world, second only to the whale shark. Historically, Basking Sharks were a familiar sight in the northern hemisphere - off the coasts of Norway, Scotland, Ireland, Canada and the USA, for example. In an 18th Century world without electricity, they became the focus of active hunting for their huge livers containing large amounts of valuable oil, primarily used in lamps.Catch numbers were small enough to leave populations largely intact, but during the 20th Century a new breed of hunter joined the fray, some driven as much by a need for adventure as for financial gain. With improved equipment and experience, they exploited the shark on an industrial scale that drastically reduced numbers, leading to localised near-extinction in some areas.From the 1970's onward a new generation took to the seas, this time with conservation in mind to identify where the shark might still be found in the waters around the British Isles, employing new technologies to solve long-standing mysteries about the behaviour of this elusive creature. Using the best of both old and new research techniques, the case was built to justify the species becoming one of the most protected sharks in the oceans.Today, the Basking Shark is a much-loved cornerstone of our natural heritage. There are positive signs that the population has stabilised and may even be slowly recovering from the damage of the past, proving that timely conservation measures can be effective.Join us on a journey amidst wild seas, places, people and conservation history in the battle to protect this iconic creature - a true sea monster's tale.

Sea Turtles: Field Research and Conservation is a comprehensive reference of experiences with sea turtle species from global experts. This book looks at the human side of protecting and studying these unique animals around the world, as well as the challenges involved, such as cultural differences and conducting research in remote locations. Led by a renowned expert in sea turtle conservation, this book addresses the largest issue facing sea turtle species currently; nearly all species of sea turtles are endangered due to poaching, fishing snares, climate change, and more. Chapters in this book range from the use of cutting-edge technology to learn more about this elusive reptile, to working with communities with long histories of sea turtle trade and consumption. It provides readers with firsthand accounts of sea turtle conservation efforts from conservationists based around the world and offers important suggestions and solutions for ensuring the future of these sea turtle species. Sea Turtles: Field Research and Conservation is the ideal resource for field biologist and marine conservationists, specifically those working in marine herpetology and with sea turtle species. Policymakers concerned with marine conservation, wildlife protection, and sustainable development, will also find this a useful reference for efforts and directions to enact change and save sea turtles from extinction.

Whether through loss of habitat or cascading community effects, diseases can shape the very nature of the marine environment. Despite their significant impacts, studies of marine diseases have tended to lag behind their terrestrial equivalents, particularly with regards to their ecological effects. However, in recent decades global research focused on marine disease ecology has expanded at an accelerating rate. This is due in part to increases in disease emergence across many taxa, but can also be attributed to a broader realization that the parasites responsible for disease are themselves important members of marine communities. Understanding their ecological relationships with the environment and their hosts is critical to understanding, conserving, and managing natural and exploited populations, communities, and ecosystems. Courses on marine disease ecology are now starting to emerge and this first textbook in the field will be ideally placed to serve them. Marine Disease Ecology is suitable for graduate students and researchers in the fields of marine disease ecology, aquaculture, fisheries, veterinary science, evolution and conservation. It will also be of relevance and use to a broader interdisciplinary audience of government agencies, NGOs, and marine resource managers.
