Spatial distribution of small thermokarst lakes of Western Siberia on imagies KH-7 and GeoEye-1

Abstract: ВведениеВ настоящее время проводятся обширные исследования эмиссии парниковых газов в ат-мосферу из водных объектов в болотно-тундровых ландшафтах в северных широтах плане-ты. Мерзлота, являясь хранилищем законсервированного углерода в обширных мерзлых торфяных болотах севера Евразии и Америки, при потеплении климата может стать источ-ником возникновения еще большего потепления при высвобождении парниковых газов [1]. По данным [2], наиболее активным источником эмиссии метана и углекислого газа в аркти-ческих и… Show more

“…A consideration of very small thaw ponds (0.005 to 0.02 ha) in thermokarst-affected regions of the WSL increases the relative surface coverage by lakes to 10%-40%, with an average value of 20%, as shown using Canopus-V data on 18 test sites from 400 to 4000 ha each [82]. However, the decreasing of the minimum lake size to less than 0.1 ha over the whole area of the WSL goes beyond the goals of the present study.…”
