Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to describe the ecology of high latitude lakes, rivers and glacial environments in both the North and South polar regions. From the lake-rich floodplains of the Arctic to the deep, enigmatic waters of Lake Vostok, Antarctica, these regions contain some of the most extraordinary aquatic ecosystems on Earth. They provide a fascinating diversity of habitats for plant, animal and microbial communities, and are proving to be valuable model systems for exploring many ecological themes including landscape-lake interactions, adaptation of life to environmental extremes, and controls on the structure and functioning of aquatic ecosystems. Some of these waters also have direct global implications, including permafrost thaw lakes as sources of greenhouse gases, subglacial aquatic environments as a storehouse of ancient microbes, and Arctic rivers as major inputs of freshwater and organic carbon to the World Ocean. Given that many polar areas are experiencing greater climate warming than at lower latitudes, these ecosystems can also be viewed as sentinels of global change. This timely volume brings together many of the world's leading researchers in polar limnology to describe these diverse aquatic environments and their ecology. It introduces each major ecosystem type, examines the similarities and differences between Arctic and Antarctic systems as well as their responses to environmental change, and describes new frontiers for future research. A glossary of terms is provided for non-specialists, and a set of colour plates introduces the ecosystems and their biota. Polar Lakes and Rivers will be of value to students and specialist researchers alike, as well as to those with a more general interest in aquatic ecology, polar environments or global change who require an authoritative overview of this fast emerging topic.
Download or read book Second Assessment of Climate Change for the Baltic Sea Basin written by The BACC II Author Team and published by Springer. This book was released on 2015-04-03 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an update of the first BACC assessment, published in 2008. It offers new and updated scientific findings in regional climate research for the Baltic Sea basin. These include climate changes since the last glaciation (approx. 12,000 years ago), changes in the recent past (the last 200 years), climate projections up until 2100 using state-of-the-art regional climate models and an assessment of climate-change impacts on terrestrial, freshwater and marine ecosystems. There are dedicated new chapters on sea-level rise, coastal erosion and impacts on urban areas. A new set of chapters deals with possible causes of regional climate change along with the global effects of increased greenhouse gas concentrations, namely atmospheric aerosols and land-cover change. The evidence collected and presented in this book shows that the regional climate has already started to change and this is expected to continue. Projections of potential future climates show that the region will probably become considerably warmer and wetter in some parts, but dryer in others. Terrestrial and aquatic ecosystems have already shown adjustments to increased temperatures and are expected to undergo further changes in the near future. The BACC II Author Team consists of 141 scientists from 12 countries, covering various disciplines related to climate research and related impacts. BACC II is a project of the Baltic Earth research network and contributes to the World Climate Research Programme.
Download or read book The Holocene written by Neil Roberts and published by John Wiley & Sons. This book was released on 2013-11-26 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Holocene provides students, researchers and lay-readers with the remarkable story of how the natural world has been transformed since the end of the last Ice Age around 15,000 years ago. This period has witnessed a shift from environmental changes determined by natural forces to those dominated by human actions, including those of climate and greenhouse gases. Understanding the environmental changes - both natural and anthropogenic - that have occurred during the Holocene is of crucial importance if we are to achieve a sustainable environmental future. Revised and updated to take full account of the most recent advances, the third edition of this classic text includes substantial material on the scientific methods that are used to reconstruct and date past environments, as well as new concepts such as the Anthropocene. The book is fully-illustrated, global in coverage, and contains case studies, a glossary and more than 500 new references.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Erie is critical in understanding regional paleoclimate and hydrology because it is the shallowest and volumetrically the smallest of the Great Lakes, therefore, it is very sensitive and vulnerable to environmental and hydrologic changes, including perturbations by humans. This study is a basic approach to evaluate past climatic history using five deep sediment cores from western, central and eastern basin of the Lake Erie. Particle size analysis (Malvern UM 2000), reflectance measurements (handheld Minolta CM-2600d), XRF analysis, XRD, MS and Age dating were carried out using homogenized sediments at 10 cm resolution. The freshwater Reservoir correction was recalculated for three basins of Lake Erie and for Lake Michigan and Huron using modern 14C dates which has previously been referred to as the `hardwater effect'. Prior calculation of the hard water effect for Lake Michigan and Lake Huron (Moore et al., 1998) varies from 226 to 375 14C yrs and 326 to 498 14C yrs respectively. The revised FWRC values obtained from published data document a generally increasing trend among the circulation pathway from Lake Michigan to Lake Huron with increasing ages of 265 ± 53 14C yrs in Southern Lake Michigan, 226 ± 61 14C yrs in Northern Lake Michigan, and 375 ± 41 14C yrs in Green Bay area. The average FWRC value for Northern Lake Huron is 348 ± 70 14C yrs; For Georgian Bay is 345 ± 70 14C yrs and Southern Lake Huron is 459 ± 61 14C yrs. Calculated freshwater reservoir correction value for Lake Erie western basin is 464 ± 51 14C yrs and the central basin is 678 ± 46 14C yrs, and for eastern basin 732 ± 64 14C yrs. The FWRC value increased from west to east in Lake Erie. These changes are likely related to basin depth, carbonate preservation differences and changes in circulation within the basins. The linear sedimentation rate (LSR) and Mass Accumulation Rate (MAR) is gradually increasing from western basin to central basin and highest is obtained in the eastern basin. Paleoclimate proxies of the Lake sediment indicate paleo-productivity, environmental changes and hydrological changes from last deglaciation. Data from sediment cores revealed that three major stratigraphy changes in sediment profiles during post younger Dryas period, Holocene Hypsithermal including Nipissing phases and Neoglacial period. These shifts in multi proxy data agree with drainage changes in Upper Great Lakes water to Lake Erie during last deglaciation and Holocene periods.
