Coastal Groundwater: Groundwater Sea Water Exchange (Waquoit Bay)


Seasonal saline outflow occurs and has been measured between 13 and 35 m from shore, but the zone likely extends to the shoreline, where measurements were not possible. Discharge measurements reveal that net saline discharge offshore over a tidal cycle (~0.026 m3/s), due only to seasonal saline exchange, is greater than the total saline outflow from other circulation mechanisms (~0.023 m3/s, which may also include some seasonal outflow).
