Seasonal thaw settlement at drained thermokarst lake basins, Arctic Alaska
Drained thermokarst lake basins (DTLBs) are ubiquitous landforms on Arctic tundra lowland. Their dynamic states are seldom investigated, despite their importance for landscape stability, hydrology, nutrient fluxes, and carbon cycling. Here we report results based on highresolution Interferometric Synthetic Aperture Radar (InSAR) measurements using space-borne data for a study area located on th...
متن کاملModeling the subsurface thermal impact of Arctic thaw lakes in a warming climate
Warming air temperatures in the Arctic are modifying the rates of thermokarst processes along Alaska’s Arctic Coastal Plain. The Arctic Coastal Plain is dominated by thaw lakes. These kilometer-scale lakes are the most visible surface features in the region, and they provide important habitats for migratory birds. The lakes are formed by thermokarst processes, and are therefore susceptible to c...
متن کاملDisappearing Arctic lakes.
Historical archived satellite images were compared with contemporary satellite data to track ongoing changes in more than 10,000 large lakes in rapidly warming Siberia. A widespread decline in lake abundance and area has occurred since 1973, despite slight precipitation increases to the region. The spatial pattern of lake disappearance suggests (i) that thaw and "breaching" of permafrost is dri...
متن کاملRecent primary production increases in arctic lakes
[1] A new application of reflectance spectroscopy enables inferences of lake sediment chlorophyll a concentrations and hence of historical trends in lacustrine primary production. In a survey of six arctic lakes on Baffin Island (Nunavut, Canada), pronounced increases of spectrally-inferred chlorophyll a concentrations are consistently expressed in sediments deposited during the 20th century. C...
