TL;DR: Climate change strongly impacts regions in high latitudes and altitudes that store high amounts of carbon in yet frozen ground, and the authors show that the consequence of these changes is global warming of permafrost at depths greater than 10 m in the Northern Hemisphere, in mountains, and in Antarctica.
Journal ArticleDOI

TL;DR: In this paper, a review of the application of multi-temporal remote sensing for monitoring changes of Arctic tundra lands is presented, focusing on results from the National Science Foundation Land-Air-Ice Interactions (LAII) program and on optical remote sensing techniques.
Journal ArticleDOI
Shrinking thermokarst ponds and groundwater dynamics in discontinuous permafrost near council, Alaska
Kenji Yoshikawa,Larry D. Hinzman +1 more
TL;DR: In this article, the authors used synthetic aperture radar (SAR) data for classification of terrain units and surface water properties, while historical aerial photographs and satellite images (IKONOS) were used for assessment of pond shrinking and recent thermokarst progression.
