Download or read book Marine Geomorphometry written by Vanessa Lucieer and published by MDPI. This book was released on 2019-06-25 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geomorphometry is the science of quantitative terrain characterization and analysis, and has traditionally focused on the investigation of terrestrial and planetary landscapes. However, applications of marine geomorphometry have now moved beyond the simple adoption of techniques developed for terrestrial studies, driven by the rise in the acquisition of high-resolution seafloor data and by the availability of user-friendly spatial analytical tools. Considering that the seafloor represents 71% of the surface of our planet, this is an important step towards understanding the Earth in its entirety. This volume is the first one dedicated to marine applications of geomorphometry. It showcases studies addressing the five steps of geomorphometry: sampling a surface (e.g., the seafloor), generating a Digital Terrain Model (DTM) from samples, preprocessing the DTM for subsequent analyses (e.g., correcting for errors and artifacts), deriving terrain attributes and/or extracting terrain features from the DTM, and using and explaining those terrain attributes and features in a given context. Throughout these studies, authors address a range of challenges and issues associated with applying geomorphometric techniques to the complex marine environment, including issues related to spatial scale, data quality, and linking seafloor topography with physical, geological, biological, and ecological processes. As marine geomorphometry becomes increasingly recognized as a sub-discipline of geomorphometry, this volume brings together a collection of research articles that reflect the types of studies that are helping to chart the course for the future of marine geomorphometry.

Available in PDF, EPUB and Kindle. Book excerpt: Fishes of the Last Frontier answers many of your fish questions and others you haven't even thought of yet in a nontechnical, plain talk voice. Learn about the fishes that are of value or special interest to Alaskans: how fish are able to survive and grow, how they get along with each other--or not--and what they eat, where and how our Alaska fishes spawn, the difference between a red and a redd, and the difference between anadromous and catadromous and why that is important. The author, a fishery scientist with nearly 50 years of experience and training, including more than 30 years in Alaska, describes the life history characteristics of 43 species of fishes valuable or important in some way to Alaskans. He delves into various aspects of biology and ecology of fish and provides insight into how humans and fish interact. The processes of fishery management in Alaska are described. Fishes of the Last Frontier includes fishes from throughout Alaska in fresh, brackish, and marine waters and sport, commercial, and subsistence fisheries. Learn not just how anadromous fish find their way home but also how scientists were able to learn the details. Nontechnical readers have reported the presentations as enjoyable, understandable, and informative.
Download or read book Sustainable Tourism in Rural Europe written by Donald Macleod and published by Routledge. This book was released on 2010-10-04 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rural Europe is a highly developed tourism region, representing advanced tourism experience and supposed modern approaches to this industry. That said, it remains highly sensitive and fragile in terms of environmental, social, economic and cultural impacts. This volume focuses on rural Europe as a fascinating example of how tourism development impacts on the communities and the environment of rural regions and offers insights into how long term sustainability could be achieved in this specific region and correspondingly in other rural parts of the world. Sustainable Tourism in Rural Europe contains contributions from leading international scholars that review and analyse the concept and practice of sustainable tourism in this region through a multidisciplinary approach that embodies the view that sustainable tourism warrants a holistic approach in terms of its impacts and development potential. Divided into three sections: Key Themes and Issues; The State and Development; The Local Community and Development, this book addresses contentious and vital issues through theory, detailed research and case studies, offering real world approaches to sustainable development, showing problems including local politics which challenge abstract models. It introduces cutting edge research dealing with contemporary developments throughout Europe and consequential lessons/implications for other rural parts of the world. This volume will be of interest to students, researchers and academics in the areas of Tourism, Geography and Environmental Studies.
Download or read book Sound Truth and Corporate Myth written by Riki Ott and published by . This book was released on 2005 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr. Riki Ott exposes the profound legacy of the Exxon Valdez oil spill and how readers can help reshape our global energy future. The author chronicles the long-lasting environmental harm to Prince William Sound, Alaska, and investigates the health problems suffered by many cleanup workers. Exxon's spill provided a portal to understanding a startling truth: oil is much more toxic than we previously thought. Sound Truth and Corporate Myth$ frames the larger story of discovery of the truly toxic nature of oil. This book shows how one particular fraction of crude oil, polycyclic aromatic hydrocarbons or PAHs, may well be the new DDT of the 21st century. In 1999, the U.S. Environmental Protection Agency listed 22 PAHs in crude oil as "persistent, bioaccumulative, and toxic (PBT) pollutants." Sharing this list of extreme human health hazards are the more commonly known pollutants--mercury, lead, dioxin, PCBs, and DDT. The latter are all highly regulated chemicals and some, such as DDT and PCBs, have been banned in the United States. Sound Truth and Corporate Myth$ traces 15 years of lingering harm to humans and wildlife from the Exxon Valdez oil spill. It reveals how corporate greed, government short-sightedness, and manipulation of the truth and the media have kept the public from learning the deadly nature of PAHs. The author provides relevant information and practical recommendations for people and policy-makers at this critical juncture in the history of civilization. This book will inspire people to reduce their own consumption of fossil fuels and, in so doing, help permanently shift society to a clean energy future.

Download or read book Cod written by George A. Rose and published by Breakwater Books. This book was released on 2007 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: The devastation of many of the greatest North Atlantic cod stocks, particularly those of Newfoundland and Labrador and the Grand Banks, has become an icon for the unsustainable relation between human exploitation and Nature. Here, George Rose tells the full story of that devastation, in scientific detail, for the first time - from the formation of the North Atlantic marine ecosystems to the massive stock declines in the last half of the 20th century. Politics and the fisheries are inextricably entwined. In Cod, Rose recounts the many political influences on the fisheries over several centuries and describes how neglect from the late 1800s onward led to insufficient scientific knowledge and little protection for the stocks when massive Euro-Russian fleets targeted the Grand Banks after World War II, destroying the most prolific fishery the world has known. Cod is no armchair account, but a controversial one that includes original information on the North Atlantic fisheries.
