| Abstract | Subterranean estuaries (STEs), the subsurface mixing zones of
terrestrial groundwater and seawater, substantially influence solute
fluxes to the oceans. Solutes brought by groundwater from land and
solutes brought from the sea can undergo biogeochemical reactions, often
mediated by microbes, which determine the composition of fluids
discharging from STEs (e.g., submarine groundwater discharge), which may
have consequences showing in coastal ecosystems. While at the local
scale (meters), processes have been intensively studied, the impact of
STE processes on solute fluxes to the coastal ocean remains poorly
constrained at the regional scale (kilometers). In the present communication, we review the processes that occur in STEs, focusing mainly on fluid flow and biogeochemical transformations of nitrogen, phosphorus, carbon, sulfur and trace metal. We highlight the spatio-temporal dynamics and measurable manifestations of those processes. The objective of this contribution is to provide a perspective on how tracer studies, geophysical methods, remote sensing and hydrogeological modeling could exploit such manifestations to estimate the regional-scale impact of processes in STEs on solute fluxes to the coastal ocean. |
