Download or read book Sea Ice written by David N. Thomas and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea ice, which covers up to 7% of the planet’s surface, is a major component of the world’s oceans, partly driving ocean circulation and global climate patterns. It provides a habitat for a rich diversity of marine organisms, and is an extremely valuable source of information in studies of global climate change and the evolution of present day life forms. Increasingly sea ice is being used as a proxy for extraterrestrial ice covered systems. Sea Ice provides a comprehensive review of our current available knowledge of polar pack ice, the study of which is severely constrained by the logistic difficulties of working in such harsh and remote regions of the earth. The book’s editors, Drs Thomas and Dieckmann have drawn together an impressive group of international contributing authors, providing a well-edited and integrated volume, which will stand for many years as the standard work on the subject. Contents of the book include details of the growth, microstructure and properties of sea ice, large-scale variations in thickness and characteristics, its primary production, micro-and macrobiology, sea ice as a habitat for birds and mammals, sea ice biogeochemistry, particulate flux, and the distribution and significance of palaeo sea ice. Sea Ice is an essential purchase for oceanographers and marine scientists, environmental scientists, biologists, geochemists and geologists. All those involved in the study of global climate change will find this book to contain a wealth of important information. All libraries in universities and research establishments where these subjects are studied and taught will need multiple copies on their shelves. David Thomas is at the School of Ocean Sciences, University of Wales, Bangor, UK. Gerhard Dieckmann is at the Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany

Available in PDF, EPUB and Kindle. Book excerpt: "Many of the papers in this volume present new and innovative research into the processes of maritime colonisation, processes that affect archaeological contexts from islands to continents. Others shift focus from process to the archaeology of maritime places from the Bering to the Torres Straits, providing highly detailed discussions of how living by and with the sea is woven into all elements of human life from subsistence to trade and to ritual. Of equal importance are more abstract discussions of islands as natural places refashioned by human occupation, either through the introduction of new organisms or new systems of production and consumption. These transformation stories gain further texture (and variety) through close examinations of some of the more significant consequences of colonisation and migration, particularly the creation of new cultural identities. A final set of papers explores the ways in which the techniques of archaelogical sciences have provided insights into the fauna of the islands and the human history of such places."--Provided by publisher.

Download or read book Ethology and Behavioral Ecology of Sea Otters and Polar Bears written by Randall W. Davis and published by Springer Nature. This book was released on 2021-07-03 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.

Download or read book Sea Mammals and Oil Confronting the Risks written by Joseph Geraci and published by Elsevier. This book was released on 2012-12-02 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea Mammals and Oil: Confronting the Risks summarizes the effects of spilled petroleum, or “oil , on five groups of marine mammals, including seals, whales and dolphins, sea otters, polar bears, and manatees. It poses questions concerning the extent of oil spill effects on marine mammals; the vulnerability of each species; and the probable effects to humans, domestic animals, and laboratory animals. After an introduction to the composition and fate of petroleum and spill-treating agents in the marine environment, the book discusses the use of risk assessment and mathematical/computer models in evaluating the effects of oil in marine mammal populations. Chapters 3 to 11 examine the ecological perspectives, physiologic, and toxic effects of oil on five mammal groups. The effect of oil on their behavior and the detection and avoidance of oil spill are also discussed. With a strong focus on risk assessment, this book is ideal for petroleum chemists and technologists, marine biologists, and veterinary medicine researchers.
