Measuring freezing and thawing in the Kola peatlands with GPR

The active layer of permafrost which freezes and thaws is seasonally monitored using ground-penetrating radar (GPR) for variation in activity and thickness, especially in response to recent climate change. Ryazantsev wanted to find out whether GPR can provide useful information about thermal factors such as soil temperature change, thermal insulation and thermal conductivity. Remote sensing…

Mounds of mires

Researchers from Tuvan and Tomsk universities wanted to understand the impact of climate change on palsa mires which are frozen mounds of peat bogs found in the highlands of southern Siberia. They are caused by permafrost and can be several metres high and up to several hundred km2 in area. When reading existing research they…
