Book excerpt: "The objective of the Yukon Ice Seasonality Experiment (YISEX) is to obtain an understanding of physical processes affecting ice cover on northern lake and river systems. Towards this goal, limnological studies were carried out during the winters of 1982/83 and 1983/84 on lake Laberge, a long (48 km), narrow (4.2 km), deep (mean depth = 54 m), medium residence-time (Tr = 1.06 a) lake in the Yukon Territory. A record is given here of the evolution of thermal structure, ice growth and decay, and the attendant meteorological and hydrological conditions"--Abstract.

Download or read book Freezing of Lakes and the Evolution of Their Ice Cover written by Matti Leppäranta and published by Springer Nature. This book was released on 2023-07-05 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book updates the first edition for the status of knowledge in the physics of lake ice and the interactions between the ice cover and the liquid water underneath. Since the first edition was written in 2013, there has been a lot of progress in the field, in particular concerning environmental questions and the impact of climate change. Life conditions in ice-covered lakes and practical matters are now brought more into the picture so that the revision also properly serves as a handbook for applications. The author has worked widely with boreal lakes, polar lakes and Central Asian lakes that provides a wide geographical spectrum. Chapter 1 gives a brief overview and presents the research fields. The second chapter contains the classification of ice-covered lakes and observation techniques, especially remote sensing. In Chapter 3, the structure and properties of lake ice are presented including optics and geochemistry. Ice growth and melting are treated in Chapter 4, while the following chapter focuses on ice mechanics with applications to traffic on ice and ice loads. Chapter 6 goes into the exotic environment of pro-glacial lakes. Chapter 7 contains the stratification and circulation of the water body beneath lake ice, Chapter 8 presents the winter ecology of freezing lakes and discusses the lake ice interface toward the society, and Chapter 9 summarizes the climate change impact on lake ice seasons. The book ends into a brief closing chapter and list of references. Research problems for student learning are listed throughout the book. Annexes are included to provide numerical data of constants and standard formulae to help practical calculations and student tasks. Lake ice closely interacts with human living conditions, but people have learnt to live with that and to utilize the ice. In the present time this is true for on-ice traffic and recreation activities. Ice fishing has become a widely enjoyed hobby, and winter sports such as skiing, skating, and ice sailing are popular activities on frozen lakes. The lake ice response to eventual climate warming would appear as a shortening of the ice season due to the increasing air temperature and also as changing of the quality of the ice seasons via changes in ice thickness and structure. The book gives the whole story of lake ice into a single volume. The second, revised edition updates the content based on recent progress in winter limnology and ice physics research and applications. The author has contributed to lake ice research since the 1980s. In particular, his topics have been lake ice structure and thermodynamics, light transfer in ice and snow, ice mechanics in large lakes, and lake ice climatology. Mathematical modeling of ice growth, drift, and decay are covered in this research.

Download or read book Encyclopedia of Snow Ice and Glaciers written by Vijay P. Singh and published by Springer Science & Business Media. This book was released on 2011-07-01 with total page 1301 pages. Available in PDF, EPUB and Kindle. Book excerpt: The earth’s cryosphere, which includes snow, glaciers, ice caps, ice sheets, ice shelves, sea ice, river and lake ice, and permafrost, contains about 75% of the earth’s fresh water. It exists at almost all latitudes, from the tropics to the poles, and plays a vital role in controlling the global climate system. It also provides direct visible evidence of the effect of climate change, and, therefore, requires proper understanding of its complex dynamics. This encyclopedia mainly focuses on the various aspects of snow, ice and glaciers, but also covers other cryospheric branches, and provides up-to-date information and basic concepts on relevant topics. It includes alphabetically arranged and professionally written, comprehensive and authoritative academic articles by well-known international experts in individual fields. The encyclopedia contains a broad spectrum of topics, ranging from the atmospheric processes responsible for snow formation; transformation of snow to ice and changes in their properties; classification of ice and glaciers and their worldwide distribution; glaciation and ice ages; glacier dynamics; glacier surface and subsurface characteristics; geomorphic processes and landscape formation; hydrology and sedimentary systems; permafrost degradation; hazards caused by cryospheric changes; and trends of glacier retreat on the global scale along with the impact of climate change. This book can serve as a source of reference at the undergraduate and graduate level and help to better understand snow, ice and glaciers. It will also be an indispensable tool containing specialized literature for geologists, geographers, climatologists, hydrologists, and water resources engineers; as well as for those who are engaged in the practice of agricultural and civil engineering, earth sciences, environmental sciences and engineering, ecosystem management, and other relevant subjects.

Download or read book The First International Lake Ladoga Symposium written by Heikki Simola and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Ladoga is the largest lake in Europe and, with its surface of 17,891 km2 and volume of 837 km3, it ranks among the top fifteen of the world's freshwater bodies. The ecological condition of Lake Ladoga is of concern to several million people living in its surroundings. There is evidence of water quality degradation and gradual eutrophication of the lake during the past decades; on the other hand, pollution control measures have improved the situation in many of the most polluted sites near industrial effluent sources. The first international Lake Ladoga Symposium was held in St. Petersburg on 22-26 November, 1993. The symposium was attended by 160 scientists, and about half of the papers presented at the symposium have been edited for this book. The contributions are grouped under the following headings: Present state of Lake Ladoga; Hydrodynamics of Lake Ladoga and other large water bodies; Water quality and pollution; Ecological studies of Lake Ladoga biota; History of Lake Ladoga and rates of change in its environment; Research methods for large lakes. Besides providing up-to-date information on the state of the lake, the papers deal with studies of many other large lakes of the cold-temperature zone and the general problems and methods of large lake research. Furthermore, the book is a valuable source of reference to the voluminous Russian limnological literature.

Download or read book Polar Lakes and Rivers written by Warwick F. Vincent and published by OUP Oxford. This book was released on 2008-09-11 with total page 352 pages. 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.
