Book Description
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.

Book Description
In Arctic Canada, Hudson Bay is a site of great exploration history, aboriginal culture, and a vast marine wilderness supporting large populations of marine mammals and birds. These include some of the most iconic Arctic animals like beluga, narwhal, bowhead whales, and polar bears. Due to the challenges of conducting field research in this region, some of the mysteries of where these animals move, and how they are able to survive in such seemingly inhospitable, ice-choked habitats are just now being unlocked. For example, are polar bears being replaced by killer whales? This new information could not be more salient, as the Hudson Bay Region is undergoing rapid environmental change due to global warming, as well as increased pressures from industrial development interests. A Little Less Arctic brings together some of the world’s leading Arctic scientists to present the current state of knowledge on the physical and biological characteristics of Hudson Bay.

Book Description
Ashley is a young woman broken by choices- some her own, some not. Looking to escape the haunting grip of her past, she embarks on a several-state winter road trip only to pass a sight that changes her life completely: jutting from a dirty snow bank, a small human hand holds its palm up to the sky. Driven by an uncharacteristic need for redemption, Ashley returns to investigate. There, she encounters a seemingly helpful, if disturbed local man and the county sheriff. It isn't until the sheriff begins to question Ashley that the terror of her situation dawns: the body in the snow isn't a snowplow accident, but a murder victim, and by coming back to investigate, Ashley has placed herself directly in the serial killers' path. As the next twenty-two hours unfold, Ashley is confronted with a terrible choice: take advantage of her one chance for escape, or attempt rescue of the killers' last remaining victim, possibly sacrificing herself in the process. Only by embracing the ghosts of her past will Ashley survive her descent into the disturbing madness of the freezing season.
