Regional trends in aquatic recovery from acidification in North America and Europe
John L. Stoddard,Dean S. Jeffries,A. Lükewille,Thomas A. Clair,Peter J. Dillon,Charles T. Driscoll,Martin Forsius,M. Johannessen,Jeffrey S. Kahl,James H. Kellogg,A. Kemp,Jaakko Mannio,Don Monteith,Peter S. Murdoch,S. Patrick,A. Rebsdorf,Brit Lisa Skjelkvåle,M. P. Stainton,T. Traaen,H. van Dam,Katherine E. Webster,J. Wieting,A. Wilander +22 more
TL;DR: This article analyzed regional trends between 1980 and 1995 in indicators of acidification (sulphate, nitrate and base-cation concentrations, and measured (Gran) alkalinity) for 205 lakes and streams in eight regions of North America and Europe.
Journal ArticleDOI
Biological Mercury Hotspots in the Northeastern United States and Southeastern Canada
David C. Evers,Young-Ji Han,Charles T. Driscoll,Neil C. Kamman,M. Wing Goodale,Kathleen F. Lambert,Thomas M. Holsen,Celia Y. Chen,Thomas A. Clair,Tom Butler +9 more
TL;DR: Biological mercury hotspots were identified in the northeastern United States and southeastern Canada using a data set of biotic Hg concentrations using eight layers representing three major taxa and more than 7300 observations were used to locate five biological Hg hotspots and nine areas of concern as discussed by the authors.
Journal ArticleDOI
Generality of fractal 1/f scaling in catchment tracer time series, and its implications for catchment travel time distributions
Sarah E. Godsey,Wenche Aas,Thomas A. Clair,Heleen A. de Wit,Ivan J. Fernandez,J. Steve Kahl,Iain A. Malcolm,Colin Neal,Margaret Neal,Sarah J. Nelson,Stephen A. Norton,Marisa C. Palucis,Brit Lisa Skjelkvåle,Chris Soulsby,Doerthe Tetzlaff,James W. Kirchner,James W. Kirchner +16 more
TL;DR: In this paper, the authors used spectral analysis of long-term tracer time series from 22 catchments in North America and Europe to demonstrate that 1/f fractal scaling of stream chemistry is a common feature of these catchments.
Journal ArticleDOI
Assessing the recovery of lakes in southeastern Canada from the effects of acidic deposition.
Dean S. Jeffries,Thomas A. Clair,Suzanne Couture,Peter J. Dillon,Jacques Dupont,Wendel Keller,D. K. McNicol,Michael A. Turner,Robert Vet,Russell Weeber +9 more
TL;DR: Chemical and biological models predict that much greater SO2 emission reductions than those presently required by legislation will be needed to promote widespread chemical and latterly, biological recovery in southeastern Canada.
Journal ArticleDOI
Predicting export of dissolved organic carbon from forested catchments in glaciated landscapes with shallow soils
TL;DR: In this article, a simple model of dissolved organic carbon (DOC) loading to surface waters that is applicable to headwater catchments in forested regions on glaciated landscapes was presented, where the proportion of wetlands within the catchments would explain the majority of variation in average annual DOC export.
