Abstract. The transformations of chemical constituents in subterranean estuaries (STEs) control the delivery nutrient loads from coastal aquifers to ocean. It is important determine processes and sources that alter concentrations at a local scale order estimate accurate regional global fluxes via submarine groundwater discharge (SGD), particularly boreal environments, where data are still very scarce. Here, biogeochemical nitrogen (N) species were examined within STE microtidal sandy beach...
Submarine groundwater discharge (SGD) is now recognized as an important coastal process affecting local and regional sources of solutes to oceans. The objective this study was compare SGD estimates through Martinique Beach (Îles-de-la-Madeleine, QC, Canada) using different sampling techniques in order quantify fluxes dissolved organic inorganic carbon (DOC, DIC) exported a embayment. These were estimated hydrogeological geochemical methods, including direct measurement via seepage meters...
Abstract Over the last 40 years, dissolved organic carbon (DOC) has been increasing in freshwater across many boreal regions. The extent to which these long‐term changes have affected lake CO 2 dynamics is unclear. We studied temporal trends DOC and pressure of (pCO ) over years 15 lakes two regions Ontario (Canada) subjected browning abatement SO deposition. Whereas from 1980 1999 there were no significant pCO any lakes, a increase was observed 2000 2017. Although concentrations increased...
Abstract The paper presents evidence of the complexity describing carbon transport from submarine groundwater discharge and chemical reactions in subterranean estuary. Vertical horizontal profiles total alkalinity (TA) dissolved inorganic (DIC) concentrations were analyzed a cross-shore transect sandy beach an evaluation DIC TA fluxes to coastal waters is proposed based on velocities hydrogeology. study was conducted Magdalen Islands Gulf St. Lawrence (QC, Canada) where unconfined sandstone...
