Weekly precipitation quantity has been measured at both at the primary meteorological site as well as at five other sites within the watershed. Daily precipitation quantity has been measured at the primary meteorological site until 2017. Weekly chemistry analysis of H+, major ions, nutrients and...

This study set out to provide an up-to-date portrait of the per- and polyfluoroalkyl substances (PFAS) contamination status in a freshwater food web from the St. Lawrence River (QC, Canada). Water, sediments, aquatic vegetation, invertebrates, and some fish species were targeted for analysis. All...

A series of surface climate parameters have been measured by members of the Climate Processes Section at the Borden Forest Research Station (44°19’N, 79°56’W) beginning in January 2006. The initial data included precipitation. In 2007, carbon dioxide fluxes from the soil (soil respiration) began...
