During the intensification of research activities in the Southern Ocean in recent years, both at national levels and through international cooperation in such projects as BIOMASS with its FIBEX and SIBEX phases, the need was felt increasingly for closer collaboration between biologists, meteorologists, and oceanographers in the study of the interaction between the atmospheric forces, the water masses, and the living resources. Better knowledge in this regard is not only of scientific interest but also of practical importance, especially for the management of the resources and the protection of the Antarctic marine ecosystem. As a follow-up on a recommendation by the IOC Program Group for the Southern Oceans made in March 1983, the Intergovernmental Oceanographic Commission organized a meeting of experts on oceanography related to the dynamics of the Antarctic ecosystems. During this meeting, held in Kiel, Federal Republic of Ger many, in May 1984, biologists and oceanographers involved in BIOMASS activities met with the oceanographers of SCOR Working Group 74 to discuss ways and means for additional physical and chemical observations in the oceanographic research within BIOMASS. It was the time when large fluctuations in the distribution of krill with subsequent detrimental effects on predator species dependent on krill had just been observed, and the question arose whether this was possibly the result of changes in the Antarctic water circulation.

The subject of the book, considering the study of the interactions between atmospheric forces, water masses, and living resources in the Southern Oceans, is not only of scientific interest but also of practical importance, especially for the management of the resources and the protection of the Antarctic marine ecosystem. What is known on the variability in the Antarctic ocean circulation and what are possible causes for such variations? To what extent and how does this variability influence primary productivity, zooplankton, and in particular, the distribution and abundance of krill? What are the subsequent effects on krill predators, such as seals, penguins, fishes and squid? The book reviews present knowledge and encourages further work in this field.

The sea ice surrounding Antarctica has increased in extent and concentration from the late 1970s, when satellite-based measurements began, until 2015. Although this increasing trend is modest, it is surprising given the overall warming of the global climate and the region. Indeed, climate models, which incorporate our best understanding of the processes affecting the region, generally simulate a decrease in sea ice. Moreover, sea ice in the Arctic has exhibited pronounced declines over the same period, consistent with global climate model simulations. For these reasons, the behavior of Antarctic sea ice has presented a conundrum for global climate change science. The National Academies of Sciences, Engineering, and Medicine held a workshop in January 2016, to bring together scientists with different sets of expertise and perspectives to further explore potential mechanisms driving the evolution of recent Antarctic sea ice variability and to discuss ways to advance understanding of Antarctic sea ice and its relationship to the broader ocean-climate system. This publication summarizes the presentations and discussions from the workshop.

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.

Antarctica is no longer a 'pole apart'. From a scientific perspective, the Antarctic ice sheet, ocean and climate systems are intimately linked with the global climate and are now seen to be of international significance for understanding climate change. From an economic perspective, the Antarctic is perceived to have great potential as a source of marine resources although the extent of speculated mineral and hydrocarbon resources is unknown. From a conservation perspective, the continent of Antarctica represents the ideal image of unspoiled wilderness. Antarctic Environments and Resources is an accessible and timely new geography of the Antarctic which examines the differing and sometimes conflicting interests in the great southern continent, the Southern Ocean and the subantarctic islands against a background of the physical and natural systems of the region and their interactions. It charts the development of human involvement in the area, focusing on the exploitation of resources from early sealing to modern fisheries, tourism and science, and it assesses the consequent impacts on the natural environment. The text also reviews the emerging framework for future environmental management developed under the Antarctic Treaty System. This is an ideal text for undergraduates studying glacial geomorphology, environmental management, polar regions and the Antarctic.

Understanding Sea-Level Rise and Variability identifies the major impacts of sea-level rise, presents up-to-date assessments of past sea-level change, thoroughly explores all of the factors contributing to sea-level rise, and explores how sea-level extreme events might change. It identifies what is known in each area and what research and observations are required to reduce the uncertainties in our understanding of sea-level rise so that more reliable future projections can be made. A synthesis of findings provides a concise summary of past, present and future sea-level rise and its impacts on society. Key Features: Book includes contributions from a range of international sea level experts Multidisciplinary Four color throughout Describes the limits of our understanding of this crucial issue as well as pointing to directions for future research The book is for everyone interested in sea-level rise and its impacts, including policy makers, research funders, scientists, students, coastal managers and engineers.

Since its discovery Antarctica has held a deep fascination for biologists. Extreme environmental conditions, seasonality and isolation have lead to some of the most striking examples of natural selection and adaptation on Earth. Paradoxically, some of these adaptations may pose constraints on the ability of the Antarctic biota to respond to climate change. Parts of Antarctica are showing some of the largest changes in temperature and other environmental conditions in the world. In this volume, published in association with the Royal Society, leading polar scientists present a synthesis of the latest research on the biological systems in Antarctica, covering organisms from microbes to vertebrate higher predators. This book comes at a time when new technologies and approaches allow the implications of climate change and other direct human impacts on Antarctica to be viewed at a range of scales; across entire regions, whole ecosystems and down to the level of species and variation within their genomes. Chapters address both Antarctic terrestrial and marine ecosystems, and the scientific and management challenges of the future are explored.

The study of Antarctic communities can provide a valuable step forward in investigating the control of community development, the utilization of habitats and the interaction among species in both species rich and species poor communities. This book contains chapters characterizing the present approaches to both aquatic and terrestrial communities in the Antarctic. From biodiversity to trophic flows, from ecophysiological strategies to the impacts of environmental change and the effects of human disturbance, this volume provides an up to the minute overview of community studies in an area covering ten percent of the Earth's surface.
