Topographic control of snow distribution in an alpine watershed of western Canada inferred from spatially-filtered MODIS snow products
snow cover fraction Quesnel River Basin snow cover duration
2009/4/28
A spatial filter (SF) is used to reduce cloud coverage in Moderate Resolution Imaging Spectroradiometer (MODIS) 8-day maximum snow cover extent products (MOD10A2) from 2000–2007, which are obtained fr...
Effects of forest harvesting on summer stream temperatures in New Brunswick, Canada: an inter-catchment, multiple-year comparison
terrain attributes solar radiation
2009/3/24
This paper presents a pre- and post-harvest comparison of stream temperatures collected in five neighbouring streams (sub-catchments) over a period of five years (1994-1998). The aim of the study was ...
Controls on the fate and transport of methylmercury in a boreal headwater catchment, northwestern Ontario, Canada
methylmercury methylation hydrology boreal catchment
2009/3/17
The fate and transport of methylmercury (MeHg) were studied in a small boreal catchment. Hydrological processes largely govern the magnitude of the flux of MeHg. Seasonal and inter-annual variability ...

2009/3/17
The potential impact of future climate change on runoff generation processes in two southern British Columbia catchments was explored using the Canadian Centre for Climate Modelling Analysis General C...
Coherent response of lakes in Ontario, Canada to reductions in sulphur deposition: the effects of climate on sulphate concentrations
Atmospheric deposition lake recovery temporal trends
2009/3/12
Sulphate deposition in south-central Ontario declined between 1976 and 2000 by more than 50%, whereas lake sulphate (SO42–) concentrations decreased by, on average, only half as much. To investigate t...
Probable changes in lake chemistry in Canada’s Atlantic Provinces under proposed North American emission reductions
Atlantic Canada monitoring networks acidification predictions MAGIC
2009/3/12
Atlantic Canada, located in the extreme north-eastern portion of North America, receives acid precipitation from all major acid emission sources on the eastern part of the continent. The region was gl...
