Book Description
The Southern Ocean surrounding the Antarctic continent is vast, in particular, its history, its isolation, and climate, making it a unique "laboratory case" for experimental evolution, adaptation and ecology. Its evolutionary history of adaptation provide a wealth of information on the functioning of the biosphere and its potential. The Southern Ocean is the result of a history of nearly 40 million years marked by the opening of the Straits south of Australia and South America and intense cooling. The violence of its weather, its very low temperatures, the formation of huge ice-covered areas, as its isolation makes the Southern Ocean a world apart. This book discusses the consequences for the evolution, ecology and biodiversity of the region, including endemism, slowed metabolism, longevity, gigantism, and its larval stages; features which make this vast ocean a "natural laboratory" for exploring the ecological adaptive processes, scalable to work in extreme environmental conditions. Today, biodiversity of the Southern Ocean is facing global change, particularly in regional warming and acidification of water bodies. Unable to migrate further south, how will she cope, if any, to visitors from the North? - Designed for curious readers to discover the immense ocean surrounding the most isolated and most inhospitable continent on the planet. - Describes the Southern Ocean facing biodiversification due to global change - Authored by scientists with experience of expeditions to the Southern Ocean

Book Description
First published in 1993, The Biology of the Southern Ocean has been referred to as international research at its best and an invaluable reference. Drawing on the considerable volume of information published in the last ten years, this second edition retains the format that made the first edition a popular bestseller, while updating the information

Book Description
The book is based on results from the Russian expedition in the region of the Antarctic Peninsula and Powell Basin in the northern part of the Weddell Sea, as well as on the review of earlier research in the region. The main goal of the research was to collect the newest data and study the physical properties and ecology of this key region of the Southern Ocean. Data analysis is supplemented with numerical modeling of the atmosphere-ocean interaction and circulation in the adjacent region, including research on rogue waves. The focus of the study was the Antarctic Circumpolar Current, currents and water properties in the Bransfield Strait and Antarctic Sound, properties of seawater, currents, ecosystem and biological communities in the Powell Basin of the northwestern Weddell Sea, and their variations. An attempt is made to reveal the role of various components of the Antarctic environment in the formation of biological productivity and maintenance of the Antarctic krill population. This is especially important as in the last decades the Antarctic environment has experienced significant changes related to the global climatic trends.

Book Description
BIOMASS (Biological Investigations of Marine Antarctic Systems and Stocks) was a unique, large-scale, long-term, international research programme established in 1977 to investigate the ecology of the Southern Ocean. Its main aim was to gain a greater understanding of the biological systems and stocks in the marine Antarctic environment, thereby providing a sound basis for the future management of the living resources within this immense ocean. The programme was drawn to a close in 1991 and its completion marked by a colloquium which brought together key researchers to summarise and review the results obtained. This volume, arising from that colloquium, provides a succinct, state-of-the-art account of the ecology of the Southern Ocean and serves as a comprehensive record of this unique and successful international project.

Book Description
Based on actual data of Soviet whaling, and reliable methodologies that existed at the time when this monograph was written, it examines the distribution and migration patterns of whales of the Southern Ocean. It defines distinct populations on the basis of phenes, as well as whale breeding zones, which are located in the adjacent to the Southern Ocean waters at lower latitudes. The book records the presence of a new species of killer whale in the Southern Ocean - Orcinus nana. Prenatal growth patterns, pregnancy and lactation duration, mean sizes of new-born whales are determined. Methods for the graphic recording of registering structures are described, and an original method for their decoding is proposed to determine animal age. The age of sexual and physical maturity, life expectancy is determined. Earlier unknown “pair formations” on the lower jaw of baleen whales and sperm whales are described, together with their macro, histological and electronic microscopic structure. The impact of the extermination of whales on the Southern Ocean ecosystem is examined, recommendations for control of the current state of whale populations are given, and perspectives of whale population recovery are estimated. Regions that could be used as testing areas for whale registration method are defined. The book is intended for biologist-cytologists, ecologists and other specialists interested in cetaceans, and for biology students.

Book Description
“This bracing history charts the myths, the exploration, and the inhabitants of the all-too-real and wild circumpolar ocean to our south.” —The Sydney Morning Herald, Pick of the Week Unlike the Pacific, Atlantic, Indian, and Arctic Oceans with their long maritime histories, little is known about the Southern Ocean. This book takes readers beyond the familiar heroic narratives of polar exploration to explore the nature of this stormy circumpolar ocean and its place in Western and Indigenous histories. Drawing from a vast archive of charts and maps, sea captains’ journals, whalers’ log books, missionaries’ correspondence, voyagers’ letters, scientific reports, stories, myths, and her own experiences, Joy McCann embarks on a voyage of discovery across its surfaces and into its depths, revealing its distinctive physical and biological processes as well as the people, species, events, and ideas that have shaped our perceptions of it. The result is both a global story of changing scientific knowledge about oceans and their vulnerability to human actions and a local one, showing how the Southern Ocean has defined and sustained southern environments and people over time. Beautifully and powerfully written, Wild Sea will raise a broader awareness and appreciation of the natural and cultural history of this little-known ocean and its emerging importance as a barometer of planetary climate change. “A sensitive portrait of a complex ecosystem, from krill to blue whales, and of the ice, winds, and currents that are critical to the circulation of the world’s oceans.” —Harper’s “Wilderness seekers will rejoice in this stirring portrait . . . McCann deftly navigates both natural glories and archival complexities.” —Nature

Book Description
This book gives a unique insight into the current knowledge of krill population dynamics including distribution, biomass, production, recruitment, growth and mortality rates. Detailed analysis is provided on food and feeding, reproduction and krill behaviour. The volume provides an overview on the aspects of natural challenges to the species, which involve predation, parasites and the commercial exploitation of the resource and its management. A chapter on genetics shows the results of population subdivision and summarizes recent work on sequencing transcriptomes for studying gene function as part of the physiology of live krill. The focus of Chapter 4 is on physiological functions such as biochemical composition, metabolic activity and growth change with ontogeny and season; and will demonstrate which environmental factors are the main drivers for variability. Further discussed in this chapter are the bottle necks which occur in the annual life cycle of krill, and the mechanisms krill have adapted to cope with severe environmental condition.
