Journal ArticleDOI
Winter stream temperature in the rain-on-snow zone of the Pacific Northwest: influences of hillslope runoff and transient snow cover
Jason A. Leach,R. D. Moore +1 more
TL;DR: In this paper, the authors examined the influence of transient snow cover on stream temperature over 13 winters and found that when snow was not present, daily stream temperature during winter rain events tended to increase with increasing air temperature.
Journal ArticleDOI
Evaluating topography-based predictions of shallow lateral groundwater discharge zones for a boreal lake–stream system
Jason A. Leach,William Lidberg,Lenka Kuglerová,Andrés Peralta-Tapia,Anneli Ågren,Hjalmar Laudon +5 more
TL;DR: In this article, the authors evaluated a topography-based prediction of subsurface discharge zones along a 1500 m headwater stream reach using temperature and water isotope tracers, showing that the predicted magnitude of groundwater inflows estimated from upslope contributing area did not always agree with tracer estimates.
Journal ArticleDOI
Empirical Stream Thermal Sensitivities May Underestimate Stream Temperature Response to Climate Warming
Journal ArticleDOI
Estimation of forest harvesting-induced stream temperature changes and bioenergetic consequences for cutthroat trout in a coastal stream in British Columbia, Canada
TL;DR: In this article, the Wisconsin Bioenergetics Model was used to simulate growth of coastal cutthroat trout (Oncorhynchus clarki CLarki) for the first year following fry emergence using the predicted and observed stream temperatures to generate scenarios representing with and no-harvest thermal regimes.
Journal ArticleDOI
Aquatic export of young dissolved and gaseous carbon from a pristine boreal fen: Implications for peat carbon stock stability
Audrey Campeau,Kevin Bishop,Michael F. Billett,Mark H. Garnett,Hjalmar Laudon,Jason A. Leach,Mats Nilsson,Mats G. Öquist,Marcus B. Wallin +8 more
TL;DR: Overall, the results demonstrate little to no mobilization of ancient C stocks from this boreal peatland and a relatively large resilience of the source of aquatic C export to forecasted hydroclimatic changes.
