Modeling hydrologic controls on particulate organic carbon contributions to beach aquifer biogeochemical reactivity

Abstract The intertidal zone of beach aquifers hosts biogeochemical transformations of terrestrially‐derived nutrients that are mediated by reactive organic carbon from seawater infiltration. While dissolved organic carbon is often assumed the sole reactive organic carbon component, advected and entrapped particulate organic carbon (POC) is also capable of supporting chemical reactions. Retarded advection of POC relative […]
