Advances in Remote Sensing Technology and the Three Poles
John Wiley & Sons Inc (Verlag)
978-1-119-78772-3 (ISBN)
Advances in Remote Sensing Technology and the Three Poles is a multidisciplinary approach studying the lithosphere, hydrosphere (encompassing both limnosphere, and oceanosphere), atmosphere, biosphere, and anthroposphere, of the Arctic, the Antarctic and the Himalayas. The drastic effects of climate change on polar environments bring to the fore the often subtle links between climate change and processes in the hydrosphere, biosphere, and lithosphere, while unanswered questions of the polar regions will help plan and formulate future research projects.
Sample topics covered in the work include:
Terrestrial net primary production of the Arctic and modeling of Arctic landform evolution
Glaciers and glacial environments, including a geological, geophysical, and geospatial survey of Himalayan glaciers
Sea ice dynamics in the Antarctic region under a changing climate, the Quaternary geology and geomorphology of Antarctica
Continuous satellite missions, data availability, and the nature of future satellite missions, including scientific data sharing policies in different countries
Software, tools, models, and remote sensing technology for investigating polar and other environments
For postgraduates and researchers working in remote sensing, photogrammetry, and landscape evolution modeling, Advances in Remote Sensing Technology and the Three Poles is a crucial resource for understanding current technological capabilities in the field along with the latest scientific research that has been conducted in polar areas.
