AB: The discharge of the fresh water component of groundwater to the near-shore marine environment is a difficult process to quantify because of numerous processes that interact to influence the rate of fluid exchange across the seabed interface. Examples are presented that illustrate some of the factors that must be considered when comparing model-based predictions of the volumetric fresh water discharge to estimates derived from either direct measurement or by inference from geochemical tracers. Two sites will be considered; one a near-shore experiment within Apalachee Bay in the northeastern Gulf of Mexico, and the other a regional-scale study of submarine groundwater discharge on the continental margin off the Mississippi River delta.
