Remote Sensing in Northern Hydrology by Claude R. Dugua Pdf

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 163. The North, with its vast and varied landscapes, sparse population, and cold climate has always challenged its explorers: physically, mentally, logistically, and technically. The scientific community in particular has known such challenges in the past and does so today, especially in light of the projected intensification of climate change at high latitudes. Indeed, there are clear signs that change is already ongoing in many environmental variables: Air temperature and annual precipitation (including snowfall) are increasing in many regions; spring snow cover extent is decreasing; lake and river ice freeze-up dates are occurring later and breakup dates earlier; glaciers are retreating rapidly; permafrost temperatures are increasing and, in many cases, the permafrost is thawing; and sea-ice extent is at record minimums and thinning.

Remote Sensing and Geospatial Approaches for Studying the Environment Affected by Human Activities by Jun Li,Xinyi Shen,Qiusheng Wu Pdf

Over recent decades, intense human activities, including urban expansion, industrial emissions, farming, deforestation, mining, tourism, and land reclamation, have significantly transformed the natural environment. These changes give rise to environmental challenges like arable land degradation, deforestation, air and water pollution. Effective environmental protection and governance are crucial, particularly in environmentally vulnerable areas like farming-pastoral transitional zones, wetlands, arid regions, coastlines, and alpine-cold regions. Remote sensing proves invaluable in assessing environmental parameters and monitoring regional or global environmental changes over long-term history. Geospatial methods, grounded in remotely sensed images and other datasets, help analyze the compounded effects of multiple factors influenced by human activities. This reprint focuses on new theories, datasets, methods, findings, and applications to address essential questions about environmental changes. It explores how to monitor changes resulting from human activities, quantify their environmental impact, and assess the combined influence of natural disturbances and human alterations. The goal is to uncover patterns and mechanisms of environmental evolution, fostering knowledge exchange and innovative research for effective environmental protection and governance.

Eurasian Arctic Land Cover and Land Use in a Changing Climate by Garik Gutman,Anni Reissell Pdf

This volume is a compilation of studies on interactions of land-cover/land-use change with climate in a region where the climate warming is most pronounced compared to other areas of the globe. The climate warming in the far North, and in the Arctic region of Northern Eurasia in particular, affects both the landscape and human activities, and hence human dimensions are an important aspect of the topic. Environmental pollution together with climate warming may produce irreversible damages to the current Arctic ecosystems. Regional land-atmosphere feedbacks may have large global importance. Remote sensing is a primary tool in studying vast northern territories where in situ observations are sporadic. State-of-the-art methods of satellite remote sensing combined with GIS and models are used to tackle science questions and provide an outlook of current land-cover changes and potential scenarios for the future. Audience: The book is a truly international effort involving U.S. and European scientists. It is directed at the broad science community including graduate students, academics and other professionals in this field.

Polar Remote Sensing by Dan Lubin,Robert Massom Pdf

The polar regions, perhaps more than any other places on Earth, give the geophysical scientist a sense of exploration. This sensibility is genuine, for not only is high-latitude ?eldwork arduous with many locations seldom or never visited, but there remains much fundamental knowledge yet to be discovered about how the polar regions interact with the global climate system. The range of opportunities for new discovery becomes strikingly clear when we realize that the high latitudes are not one region but are really two vastly di?erent worlds. The high Arctic is a frozen ocean surrounded by land, and is home to fragile ecosystems and unique modes of human habitation. The Antarctic is a frozen continent without regular human habitation, covered by ice sheets taller than many mountain ranges and surrounded by the Earth’s most forbidding ocean. When we consider global change as applied to the Arctic, we discuss impacts to a region whose surface and lower atmospheric temperatures are near the triple point of water throughout much of the year. The most consistent signatures of climate warming have occurred at northern high latitudes (IPCC, 2001), and the potential impacts of a few degrees increase in surface temperature include a reduction in sea ice extent, a positive feedback to climate warming due to lowering of surface albedo, and changes to surface runo? that might a?ect the Arctic Ocean’s salinity and circulation.

Arctic Hydrology, Permafrost and Ecosystems by Daqing Yang,Douglas L. Kane Pdf

This book provides a comprehensive, up-to-date assessment of the key terrestrial components of the Arctic system, i.e., its hydrology, permafrost, and ecology, drawing on the latest research results from across the circumpolar regions. The Arctic is an integrated system, the elements of which are closely linked by the atmosphere, ocean, and land. Using an integrated system approach, the book’s 30 chapters, written by a diverse team of leading scholars, carefully examine Arctic climate variability/change, large river hydrology, lakes and wetlands, snow cover and ice processes, permafrost characteristics, vegetation/landscape changes, and the future trajectory of Arctic system evolution. The discussions cover the fundamental features of and processes in the Arctic system, with a special focus on critical knowledge gaps, i.e., the interactions and feedbacks between water, permafrost, and ecosystem, such as snow pack and permafrost changes and their impacts on basin hydrology and ecology, river flow, geochemistry, and energy fluxes to the Arctic Ocean, and the structure and function of the Arctic ecosystem in response to past/future changes in climate, hydrology, and permafrost conditions. Given its scope, the book offers a valuable resource for researchers, graduate students, environmentalists, managers, and administrators who are concerned with the northern environment and resources.

Global Climate Change and Cold Regions Ecosystems by John M. Kimble Pdf

Global Climate Change and Cold Regions Ecosystems provides information on soil processes and the carbon cycle in cold ecoregions as well as the soil carbon pool and its fluxes in the soils of cold ecoregions. Filling a void in this area of soil science, this resource explains soil processes influencing C dynamics under natural and disturbed ecosystems. The soils of the cold region ecosystems serve as a net sink of atmospheric C. However, an increase in global temperature could render them a net source. In the event of global warming, the cold regions ecosystems-arctic, sub-arctic, alpine, Antarctic, boreal forests, and peatlands-will undergo radical changes. Potential environmental change could drastically increase the active soil layer and influence the large C pool found in them. Topics include: soil C pools in different cold ecoregions, the impact of natural and anthropogenic disturbances on the soil C pool, the method of assessment of C and other properties of soils of the cold regions ecosytems while focusing on the fate of C in permafrost soils. Global Climate Change and Cold Regions Ecosystems covers the current and possible future effects of the cold ecoregions soil C pool on the global carbon pool.

Responses to Climate Change in the Cold Biomes by Hans J. De Boeck,Erika Hiltbrunner,Anke Jentsch,Vigdis Vandvik Pdf

Climate change is thought to be especially relevant to ecosystems in the cold biomes. Observed warming has been higher in cold climates through various positive feedbacks, especially declining snow and ice cover, and climate projections indicate further rapid warming in the decades to come. Temperature change can have profound impacts in cold biome ecosystems, either directly in terms of impacts on physiology or growing season length, or indirectly via changes in nutrient cycling. The regions focused on here are the (sub)arctic and the (sub)alpine areas, both characterized by short growing seasons and low annual temperatures, but with different radiation environments depending on latitude. Climate change can have impacts in all seasons. Increased spring temperatures can accelerate snowmelt, leading to an earlier onset of the growing season, while warmer summers may stimulate primary productivity through temperatures closer to metabolic optima and/or increased mineralization rates. Winter warming can lead to the vegetation being damaged because of exposure to harsh frost without insulating snow cover. In all of this, concurrent changes in precipitation also play an important role: increased snowfall can buffer warming-induced advances in snowmelt, a higher ratio of rain to snow can greatly accelerate snowmelt in winter and spring, and summer drought may reverse growth-stimulation by warming directly (drought stress) or indirectly (e.g. impaired nutrient uptake). Micro-climate is crucial in these systems and requires particular attention as it can vary widely across the landscape, creating different growing environments in the space of a few meters or even less. Interest in cold region responses to climate change does not only arise from the fact that they harbor unique ecosystems that may be endangered, but also because they store large amounts of carbon that may be released under climate change. However, research is challenging because of the remoteness of many of these areas and the harsh conditions during much of the year. In spite of this, some studies have been carried out over an extensive period, spanning decades and yielding information on for example plant community reorganization (including invasions), and changes in phenology above- and/or belowground. Other studies focus on shorter term effects, such as impacts of heat waves, late frosts or other anomalous weather, including longer term (after-) effects that may differ drastically from other regions because of the short growing season in cold climates. Ultimately, models are used to predict future changes in vegetation along latitudinal or elevational gradients, although phenology and microclimatic variation may pose particular challenges. Contributions to this Research Topic focus on climate change, encompassing both changes in the mean (gradual warming) and variability (heat waves, altered precipitation distribution) in cold biomes. The Topic contains reports on observed changes or events, but also research making use of experimentally imposed environmental changes. The focus is varied, including phenology, physiology, soil and vegetation science and biogeochemistry, with the aim of providing a comprehensive overview of observed and expected responses to climate change in cold biome ecosystems.
