Collaborative Research: Are Carbon Fluxes from Marine Sediments Enhanced by Submarine Ground Water Discharge?
Goals and Objectives
Water flow into estuaries is one of the primary controls on the quantities and distributions of dissolved constituents including pollutants and nutrients. Flow paths for water and associated constituents that can be easily quantified for estuaries include surface water runoff, atmospheric deposition, and evapotranspiration. One additional and potentially significant source of water that is more difficult to quantify is the submarine discharge of ground water (SGD). Previously, this term has been defined to include both marine and terrestrially derived ground water components, but the magnitude of this SGD has been poorly defined because of difficulties associated with locating and measuring the flow and perhaps by uncertainties about its composition. The marine component of SGD represents an important flux of water across the sediment–water interface. Processes that drive recirculation of seawater through sediments, or the marine SGD, and create a subterranean mixing zone also set up a critical boundary zone for diagenetic reactions.
