Development of an Automated Seepage Meter for Quantifying Submarine Groundwater Discharge in the Coastal Zone

Nutrient-rich, submarine groundwater discharge (SGD) seeps into neighboring bodies of water may result in the eutrophication of salt marshes, bays and other coastal waters. This project seeks to deliver SGD measurement technology to oceanographers, industry and coastal managers through the development of a low-cost and easy to operate automated seepage meter. The key innovation in this new seepage meter will be the development of a low power, low cost spectrophotometric sensor for determining groundwater flow based on dye dilution.
