Book Description
Many factors influence the formation of shipwreck sites: the materials from which the ship was built, the underwater environment, and subsequent events such as human activity, storms, and chemical reactions. In this first volume to comprehensively catalogue the physical and cultural processes affecting submerged ships, Matthew Keith brings together experts in diverse fields such as geology, soil and wood chemistry, micro- and marine biology, and sediment dynamics. The case studies identify and examine the natural and anthropogenic processes--corrosion and degradation on one hand, fishing and trawling on the other--that contribute to the present condition of shipwreck sites. The contributors also discuss how these varied and often overlapping events influence the archaeological record. Offering an in-depth analysis of emerging technologies and methods—acoustic positioning, computer modeling, and site reconstruction--this is an essential study for the research and preservation of submerged heritage sites.

Book Description
The Atlantic Walrus: Multidisciplinary insights into human-animal interactions addresses the key dimensions of long-term human walrus interactions across the Atlantic Arctic and subarctic regions, over the past millennia. This book brings together research from across the social and natural sciences to explore walrus biology, human culture, environmental conditions and their reciprocal effects. Together, 13 chapters of this book reconstruct the early evolution of walruses, walrus biology, the cultural significance and ecological impact of prehistoric and indigenous hunting practices, as well as the effects of commercial hunting and international trade. This book also examines historic and ongoing management strategies and, the importance of new research methodologies in revealing hitherto unknown details of the past, and concludes by discussing the future for Atlantic walruses in the face of climate change and increased human activities in the Arctic. This volume is an ideal resource for those who are seeking to understand an iconic Arctic species and its long and complex relationship with humans. This includes individuals and researchers with a personal or professional connection to walruses or the Arctic, as well as marine biologists, zoologists, conservationists, paleontologists, archaeologists, anthropologists, historians, indigenous communities, natural resource managers and government agencies. - Provides succinct overviews of the biology of the Atlantic Walrus (Odobenus rosmarus rosmarus) as well as human cultures within the North Atlantic Arctic and the surrounding region by consolidating research which until now has been scattered across fields and academic publications - Editorial team of inter-disciplinary researchers ensuring the breadth, depth and integration of material covered throughout the volume - Thirteen chapters, each authored by leading international researchers and experts on the Atlantic Walrus - Considers the inter-relatedness and complexity of species biology, ecological change, human culture, and anthropogenic pressures onto the Atlantic Walrus, all while remaining accessible to readers from different disciplines or a more generalist audience - Draws upon the latest methods in marine mammal and archaeological research - Assesses historical management of the species, while also considering current and future conservation efforts in light of human activities and climate change - Text supported by striking and insightful new maps and scientific illustrations, ideal for teaching and outreach

Book Description
Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.
