Many marine mammals communicate by emitting sounds that pass through water. Such sounds can be received across great distances and can influence the behavior of these undersea creatures. In the past few decades, the oceans have become increasingly noisy, as underwater sounds from propellers, sonars, and other human activities make it difficult for marine mammals to communicate. This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also examined. An essential addition to any marine biologist's library, Marine Mammals and Noise will be especially appealing to marine mammalogists, researchers, policy makers and regulators, and marine biologists and oceanographers using sound in their research.

In the early eighteenth century, West Greenland became a colonial territory of Denmark. Nevertheless, a large number of Inuit communities maintained significant aspects of their cultural and economic practices. When home rule was introduced in 1979, the benign paternalism of colonial days was superseded by the incorporation of ethnic and institutional relations under a unified political system in Greenland. A national Greenlandic Inuit community was created, forcing further cultural adaptation on the part of the Inuit. Jens Dahl analyses life in Saqqaq, a small Greenlandic hunting community, and explores the changes that have taken place there over the last couple of decades. As modern technology is introduced and the worldviews of the Greenlandic Inuit change, the hunting community continues to base its life on a traditional notions, including an economy involving sharing, exchanging, and free access to the hunting and fishing grounds. Dahl demonstrates that Saqqaq and other communities have adapted to colonial and post-colonial influences by combining their practices of hunting and fishing with other forms of employment. In the midst of these economic developments, however, hunters are losing control over their traditional lands. Dahl discusses this conflict within the political context, making "Saqqaq" a unique and valuable example of Inuit survival in the modern world.

The meeting of Aquatic Noise 2013 will introduce participants to the most recent research data, regulatory issues and thinking about effects of man-made noise and will foster critical cross-disciplinary discussion between the participants. Emphasis will be on the cross-fertilization of ideas and findings across species and noise sources. As with its predecessor, The Effects of Noise on Aquatic Life: 3rd International Conference will encourage discussion of the impact of underwater sound, its regulation and mitigation of its effects. With over 100 contributions from leading researchers, a wide range of sources of underwater sound will be considered.

In this landmark new work, the major authorities in the field from around the world present a wealth of research data, coverage of regulatory issues, and thinking about the effects of man-made noise on marine mammals, turtles, amphibians, fishes, and invertebrates. The various themes of the book were chosen to cover the wide range of basic and cutting edge information on this topic. They include the hearing abilities of aquatic animals; communication by means of underwater sound; the description of aquatic soundscapes; different sound sources and their characteristics; the effects of sound on behavior; and assessing, mitigating, and monitoring the effects of aquatic noise. Emphasis is on the cross-fertilization of ideas and findings across species and noise sources. With over 140 contributions from leading researchers, the sources of underwater sound and their effects are discussed in detail.
