Rapid initialization of retrogressive thaw slumps in the Canadian high Arctic and their response to climate and terrain factors
MKW Jones, WH Pollard… - Environmental Research …, 2019 - iopscience.iop.org
An increase in retrogressive thaw slump (RTS) activity has been observed in the Arctic in
recent decades. However, a gap exists between observations in high Arctic polar desert …
