Fig. 3: Implications of the redistribution of fluvial energy across a lengthening summer thaw season in small High Arctic watersheds (10 km2) underlain by continuous permafrost.
From: Emerging dominance of summer rainfall driving High Arctic terrestrial-aquatic connectivity
Daily mean (±1 SD) air temperature (2003–2019), active layer depth (2012–2019), growing degree day (GDD; 2003–2019) and total daily rainfall (2003–2019) from the CBAWO. A shift in higher stream powers to later in the summer/fall shoulder season enhances the potential for terrestrial-aquatic connectivity in response to rainfall inputs when annual summer air temperatures, active layer depths, and vegetation productivity are at their annual maximums.
