Sediment degradation experiments for a low gradient stream suggest the watershed’s connectivity regime exhibits control on stream biogeochemistry
We carried out aerobic incubation experiments to assess oxidation and mineralization-nitrification rates and changes in stable isotopic ratios for sediment and dissolved organic matter and nitrate.

Linking seasonal changes in organic matter composition and nutrients to shifting hydraulic gradients in coastal urban canals
We investigate how time-variable interactions among coastal water source contributions influence the concentrations of dissolved organic carbon (DOC), nutrients, and DOM composition in urban canals..
