The Gray Whale: Eschrichtius robustus provides an introduction to the understanding of Eschrichtius robustus or the gray whale. This book explores the life processes, reproduction, and growth of large cetacean populations. Organized into four parts encompassing 25 chapters, this book begins with an overview of the gray whale evolution, fossils, and subfossil remains, range, and systematics in historical times. This text then presents the historical of gray whale exploitation and the economic importance of these whales to humans. Other chapters consider the gray whale migration, abundance, and seasonal distribution in the wake of the California population's recovery from depletion. This book discusses as well the methods used in shore-based censuses during migration and in aerial surveys of gray whales taken on their winter grounds. The final chapter deals with some innovative approaches to the study of free-ranging cetaceans. This book is a valuable resource for anthropologists, paleontologists, biologists, and naturalists.

Once hunted by whalers and now the darling of ecotourists, the gray whale has become part of the culture, history, politics, and geography of Mexico's most isolated region. After the harvesting of gray whales was banned by international law in 1946, their populations rebounded; but while they are no longer hunted for their oil, these creatures are now chased up and down the lagoons of southern Baja California by whalewatchers. This book uses the biology and politics associated with gray whales in Mexican waters to present an unusual case study in conservation and politics. It provides an inside look at how gray whale conservation decisions are made in Mexico City and examines how those policies and programs are carried out in the calving grounds of San Ignacio Lagoon and Magdalena Bay, where catering to ecotourists is now an integral part of the local economy. More than a study of conservation politics, Dedina's book puts a human face on wildlife conservation. The author lived for two years with residents of Baja communities to understand their attitudes about wildlife conservation and Mexican politics, and he accompanied many in daily activities to show the extent to which the local economy depends on whalewatching. "It is ironic," observes Dedina, "that residents of some of the most isolated fishing villages in North America are helping to redefine our relationship with wild animals. Americans and Europeans brought the gray whale population to the brink of extinction. The inhabitants of San Ignacio Lagoon and Magdalena Bay are helping us to celebrate the whales' survival." By showing us how these animals have helped shape the lifeways of the people with whom they share the lagoons, Saving the Gray Whale demonstrates that gray whales represent both a destructive past and a future with hope.

"Eye of the Whale focuses on one great whale in particularthe coastal-traveling California gray whale. Gray whales make the longest migration of any mammal - from the lagoons of Baja California to the feeding grounds of the Bering Strait between Alaska and Siberia (nearly 6,000 miles). That the gray whale exists today is nothing short of miraculous. Whaling fleets twice massacred the species to near extinction - first during the nineteenth century and again during the early part of the twentieth century."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

The South Atlantic plays a critical role in the couplingofoceanic processes between the Antarctic and the lower latitudes. The Antarctic Ocean, along with the adjacent southern seas, is of substantial importance for global climate and for the distributionofwater masses because itprovides large regions ofthe world ocean with intermediate and bottom waters. In contrast to the North Atlantic, the Southern Ocean acts more as an "information distributor", as opposed to an amplifier. Just as the North Atlantic is influencedby the South Atlantic through the contributionofwarm surface water,the incomingsupply ofNADW - in the area of the Southern Ocean as Circumantarctic Deep Water - influences the oceanography ofthe Antarctic. The competing influences from the northern and southern oceans on the current and mass budget systems can be best studied in the South Atlantic. Not only do changes in the current systems in the eastern Atlantic high-production regions affect the energy budget, they also influence the nutrient inventories, and therefore impact the entire productivity ofthe ocean. In addition, the broad region of the polar front is a critical area with respect to productivity-related circulation since it is the source of Antarctic Intermediate Water. Although theAntarctic Intermediate Watertoday liesdeeper than the water that rises in the upwelling regions, it is the long-term source ofnutrients that are ultimately responsible for the supply oforganic matter to the sea floor and to sediments.
