Monitoring Inter- and Intra-Seasonal Dynamics of Rapidly Degrading Ice-Rich Permafrost Riverbanks in the Lena Delta with TerraSAR-X Time Series
Arctic warming is leading to substantial changes to permafrost including rapid degradation of ice and ice-rich coasts and riverbanks. In this study, we present and evaluate a high spatiotemporal resolution three-year time series of X-Band microwave satellite data from the TerraSAR-X (TSX) satellite to quantify cliff-top erosion (CTE) of an ice-rich permafrost riverbank in the central Lena Delta...
متن کاملMonitoring Bedfast Ice and Ice Phenology in Lakes of the Lena River Delta Using TerraSAR-X Backscatter and Coherence Time Series
Thermokarst lakes and ponds are major elements of permafrost landscapes, occupying up to 40% of the land area in some Arctic regions. Shallow lakes freeze to the bed, thus preventing permafrost thaw underneath them and limiting the length of the period with greenhouse gas production in the unfrozen lake sediments. Radar remote sensing permits to distinguish lakes with bedfast ice due to the dif...
متن کاملUsing Terrasar-x Imagery for the Monitoring of Permafrost Dynamics in Northern Quebec
Due to its high spatial resolution, TerraSar-X imagery offers new possibilities to observe and monitor the Earth and provide information about small scale landscape features. Such small-scale targets are the so-called lithalsas – typical permafrost features in the discontinuous permafrost zone forming mounds between 5 and 10 m in height and up to several 100 m2 in size. Those lithalsas are expe...
