Book Description
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.
Seafloor Geomorphology as Benthic Habitat
Author: Peter T HarrisPublisher: Elsevier

Category : Science
Languages : en
Pages : 1076
Book Description
Seafloor Geomorphology as Benthic Habitat: GeoHab Atlas of Seafloor Geomorphic Features and Benthic Habitats, Second Edition, provides an updated synthesis of seabed geomorphology and benthic habitats. This new edition includes new case studies from all geographic areas and habitats that were not included in the previous edition, including the Arctic, Asia, Africa and South America. Using multibeam sonar, the benthic ecology of submarine features, such as fjords, sand banks, coral reefs, seamounts, canyons, mud volcanoes and spreading ridges is revealed in unprecedented detail. This timely release offers new understanding for researchers in Marine Biodiversity, environmental managers, ecologists, and more. Explores the relationships between seabed geomorphology, oceanography and biology Provides global case studies which directly focus on habitats, including both biological and physical data Describes ways to detect change in the marine environment (change in the condition of benthic habitats), a critical aspect for judging the performance of policies and legislation
The Nature of Southeast Alaska

Category : Nature
Languages : en
Pages : 429
Book Description
“Unlike the standard nature guides that explain how to recognize common animals, Nature stresses the web of interrelationships that link the regional flora and fauna. This affectionate examination of some of North America’s most spectacular surviving old-growth forests will delight backpackers and armchair naturalists.” —Los Angeles Times Book Review Everything you ever wanted to know about the flora and fauna of Southeast Alaska is contained in the third edition of this lively field guide to the natural world, from bears to banana slugs, mountains to murrelets. The authors, who are both Alaskan residents and biologists, combine scientific research with personal experiences to make a definitive field guide for residents of or visitors to Southeast Alaska. The unique features of the book include: In-depth information about how wildlife coexists with the environment Detailed discussions of mammals, birds, fish, invertebrates, fungi, and plants Detailed map of wilderness areas in Southeast Alaska More than 200 black-and-white illustrations A bibliography, list of common and scientific names, and an index New to this edition: More than 100 new illustrations, many never before published, as well as new maps and photos Major expansion of sections on geology, old-growth forests, marine mammals, and amphibians Fifty-two new sidebars—written in the first person to give the text a more personal touch—that describe recent findings or experiences. Sweeping updates and elaborations to chapter narratives—often thanks to technology unknown in 1992. In-depth guide to Southeast Alaska’s flora and fauna; more than an identification manual, Nature explores how the species and habitats encountered in the woods and waters of Southeast Alaska fit into the bigger picture.

Book Description
Seals, seabirds, whales and dolphins are at the top of marine food chains: studying their ecology can help identify and monitor changes in wider marine ecosystems. This book examines our current understanding of marine predator ecology and investigates how it can be used in management and conservation of marine habitats.

Fishes of the Last Frontier
Author: Bill HauserPublisher: Publication Consultants
ISBN: 1594335230
Category : Nature
Languages : en
Pages : 320
Book Description
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.
Sound Truth and Corporate Myth$
Author: Riki OttPublisher:
ISBN:
Category : Alaskan nonfiction
Languages : en
Pages : 604
Book Description
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.
