Yamal lakes (Siberia): properties derived from optical and SAR remote sensing
In this study a number of approaches was used to understand the process of organic transport to the lakes in several key sites of Russian Arctic. Among these approaches were i) direct field observations of “lake – catchment” systems, water sampling (2011-2014), geodetic (2011, 2014) and bathymetric...
