Active‐layer mapping at regional scales: a 13‐year spatial time series for the Kuparuk region, north‐central Alaska
Abstract Results from extensive, spatially‐oriented field investigations conducted in the Kuparuk River region of north‐central Alaska were used in conjunction with a simple analytical procedure to provide a comprehensive analysis of active‐layer variability under contemporary climate. This approach...
