Based on the research findings of 60 years, the author describes the origins of the Agulhas Current, its behaviour, its influence on the adjacent continental shelf, its effect on local weather and its role in linking the Indian and Atlantic Oceans. The text is well-illustrated and includes asides on the history of research on the Current. An exhaustive bibliography gives easy access to present knowledge on this important current system.

Throughout the twentieth century, glaciologists and geophysicists from Denmark, Norway and Sweden made important scientific contributions across the Arctic and Antarctic. This research was of acute security and policy interest during the Cold War, as knowledge of the polar regions assumed military importance. But scientists also helped make the polar regions Nordic spaces in a cultural and political sense, with scientists from Norden punching far above their weight in terms of population, geographical size or economic activity. This volume presents an image of Norden that stretches far beyond its conventional limits, covering a vast area in the North Atlantic and the Arctic Sea, as well as parts of Antarctica. Rich in resources, scarce in population, but critically important in global and regional geopolitics, these spaces were contested by major powers such as Russia, the United States, Canada and, in the Antarctic, Argentina, Australia, South Africa and others. The empirical focus on Danish, Norwegian and Swedish influence in the polar regions during the twentieth century embraces a diverse array of themes, from the role of science in policy and diplomacy to the tensions between nationalism and internationalism, with clear relevance to the important role science plays in contemporary discussions about Nordic engagement with the polar regions.

This book provides a modern, synthetic overview of what is known about the structure, functioning and interactions of marine and terrestrial systems at the Prince Edward Islands. Building on more than 50 years of biological, geological, meteorological, and oceanographic research, it demonstrates not only how inextricably linked marine and terrestrial systems at the islands are, but also how global environmental challenges, such as climate change, biological invasions, and over exploitation, are playing out at the regional and local levels in the Southern Ocean.

This memoir is the first to review all of Antarctica’s volcanism between 200 million years ago and the Present. The region is still volcanically active. The volume is an amalgamation of in-depth syntheses, which are presented within distinctly different tectonic settings. Each is described in terms of (1) the volcanology and eruptive palaeoenvironments; (2) petrology and origin of magma; and (3) active volcanism, including tephrochronology. Important volcanic episodes include: astonishingly voluminous mafic and felsic volcanic deposits associated with the Jurassic break-up of Gondwana; the construction and progressive demise of a major Jurassic to Present continental arc, including back-arc alkaline basalts and volcanism in a young ensialic marginal basin; Miocene to Pleistocene mafic volcanism associated with post-subduction slab-window formation; numerous Neogene alkaline volcanoes, including the massive Erebus volcano and its persistent phonolitic lava lake, that are widely distributed within and adjacent to one of the world’s major zones of lithospheric extension (the West Antarctic Rift System); and very young ultrapotassic volcanism erupted subglacially and forming a world-wide type example (Gaussberg).

The Antarctic provides a suite of scenarios useful for investigating the range of climate change effects on terrestrial and limnetic biota. The purpose of the book is to provide, based on the most up to date knowledge, a synthesis of the likely effects of climate change on Antarctic terrestrial and limnetic ecosystems and, thereby, to contribute to their management and conservation, based on the information.

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.
