Available in PDF, EPUB and Kindle. Book excerpt: The second volume of “Adaptation and Evolution in Marine Environments – The Impacts of Global Change on Biodiversity” from the series “From Pole to Pole” integrates the marine biology contribution of the first tome to the IPY 2007-2009, presenting overviews of organisms (from bacteria and ciliates to higher vertebrates) thriving on polar continental shelves, slopes and deep sea. The speed and extent of warming in the Arctic and in regions of Antarctica (the Peninsula, at the present ) are greater than elsewhere. Changes impact several parameters, in particular the extent of sea ice; organisms, ecosystems and communities that became finely adapted to increasing cold in the course of millions of years are now becoming vulnerable, and biodiversity is threatened. Investigating evolutionary adaptations helps to foresee the impact of changes in temperate areas, highlighting the invaluable contribution of polar marine research to present and future outcomes of the IPY in the Earth system scenario.

Available in PDF, EPUB and Kindle. Book excerpt: The wreck in 1866 of the General Grant in the desolate sub-Antarctic Auckland Islands is one of the world’s great nautical mysteries, a story that still tantalises and thrills. When the ship was crushed in a cave beneath a sheer cliff face, a few crew members and a handful of passengers managed to escape in a lifeboat. For more than two years they lived a hand-to-mouth existence on a nearby island before they were rescued. This story is extraordinary in itself, but soon compelling legends spread that the ship had sunk with a fabulous hoard of gold from the Victorian goldfields. For 140 years, expeditions and bounty hunters have searched for the ship and her elusive cargo. In the relentless seas of the Auckland Islands, it has been a soul-destroying endeavour. Locating the vessel has been difficult enough; finding the gold has proved impossible – unless one of those early expeditions really did find it … In this book Madelene Ferguson Allen and Ken Scadden tell the full story of the voyage from Melbourne, the shipwreck, the plight of the castaways and the search for the gold. At this distance in time, separating the facts from the legends is difficult, but they have scrupulously researched the events of the shipwreck and examined every subsequent search for the gold. The story is more remarkable than fiction, a tale of heroes and cads, heartbreak and loss, hope and despair, hunger and greed. As it has bewitched so many in the past, so it will haunt readers long after the last page is turned.

Download or read book Antarctic Ecosystems written by Alex D. Rogers and published by John Wiley & Sons. This book was released on 2012-03-12 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2010-09-02 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although international scientific cooperation - particularly in meteorology - was established previous to the first International Polar Year, the IPY-1 (1882-83) is considered to be the first revolutionary step towards an extensive international cooperation in the polar areas for the benefit of science rather than national prestige and territorial gain. This was followed by IPY-2 (1932-33) and IPY-3 - actually the International Geophysical Year (1957-58) - before the crowning effort of IPY-4 (2007-08). The history of these years is recounted here and explains the political, economic, technical and scientific conditions and expectations that laid the basis for each IPY and which gradually expanded both the scope and extent of our understanding of the complexities in polar regions

Download or read book In a Crystal Land written by Dean Beeby and published by . This book was released on 1994 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In a Crystal Land for the first time chronicles the adventures of Canadians who, often at the risk of their lives, contributed to the exploration of Antarctica, the last terrestrial frontier. More than a dozen Canadians were recruited as members of landmark south polar expeditions, largely for their cold-weather expertise. Physicists, geologists, surveyors, dog-drivers, aviators - many of them were the first to set eyes on Antarctica's ice plains, nunataks, mountain ranges, and glaciers. Their stories are told here, based on accounts found in journals, logbooks, and letters, and, in some cases, on personal interviews." "From a Victorian expedition (1899-1900) that was the first to winter on the continent, to the first multinational assault on Antarctica; from a windswept encampment named Camp Winnipeg to the 'crystalline chambers and sapphire corridors' of the Ross Ice Shelf, Dean Beeby animates a wealth of research uncovering tales of bravery and madness, heartbreak and revelry. In a Crystal Land restores these Canadians to their rightful place in the history of Antarctic exploration."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Antarctic Subglacial Aquatic Environments written by Martin J. Siegert and published by American Geophysical Union. This book was released on 2011-01-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 192. Antarctic Subglacial Aquatic Environments is the first volume on this important and fascinating subject. With its underlying theme of bridging existing knowledge to future research, it is a benchmark in the history of subglacial lake exploration and study, containing up-to-date discussions about the history and background of subglacial aquatic environments and future exploration. The main topics addressed are identification, location, physiography, and hydrology of 387 subglacial lakes; protocols for environmental stewardship and protection of subglacial lake environments; details of three programs aiming to explore Vostok Subglacial Lake, Ellsworth Subglacial Lake, and Whillans Subglacial Lake over the next 3–5 years; assessment of technological requirements for exploration programs based on best practices for environmental stewardship and scientific success; and knowledge of subglacial lakes as habitats for microbial life and as recorders of past climate and ice sheet change. Its uniqueness, breadth, and inclusiveness will appeal to microbiologists and those interested in life in extreme environments, paleoclimatologists and those interested in sedimentary records of past changes, glaciologists striving to understand how water beneath glaciers affects their flow, and those engaged in developing technology to undertake direct measurement and sampling of extreme environments on Earth and in the solar system.

This book was released on 2013-06-29 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic troposphere (0 to ca. 8 km) plays an important role in environmental concerns for global change. It is a unique chemical reactor influenced by human activity and the Arctic ocean. It is surrounded by industrialized continents that in winter contribute gaseous and particulate pollution (Arctic haze). It is underlain by the flat Arctic ocean from which it is separated by a crack-ridden ice membrane 3 to 4 m thick. Ocean to atmosphere exchange of heat, water vapor and marine biogenic gases influence the composition of the reactor. From September 21 to December 21 to March 21, the region north of the Arctic circle goes from a completely sunlit situation to a completely dark one and then back to light. At the same time the lower troposphere is stably stratified. This hinders vertical mixing. During this light period, surface temperature reaches as low as -40°C. In this environment, chemical reactions involving sunlight are generally much slower than further south. Thus, the abundance of photochemically reactive compounds in the atmosphere can be high prior to polar sunrise. Between complete dark in February and complete light in April, a number of chemical changes in the lower troposphere take place.
