Measurement of submarine groundwater discharge in Kahana Bay, O‘ahu, Hawai‘i
Submarine groundwater discharge (SGD) is neither well understood nor commonly investigated in Hawai‘i, but it is recognized as a potential pollution source to coastal environments. Between 1998 and 2000, this study located and quantified both total SGD and the terrestrial SGD fraction ( ftgw) in Kahana Bay, O‘ahu. CTD casts were used to profile the water structure and identify potential areas o...
متن کاملInvestigation of submarine groundwater discharge
Coastal hydrogeologists and oceanographers now recognize the potentially significant contribution that submarine groundwater discharge (SGD) could make to the coastal ocean. SGD may be both volumetrically and chemically important to coastal water and chemical budgets. A worldwide compilation of observed SGD shows that groundwater seepage from the land to the ocean occurs in many environments al...
متن کاملSubmarine groundwater discharge in Northern Monterey Bay, California: Evaluation by mixing and mass balance models
Article history: Received 28 July 2015 Received in revised form 19 January 2016 Accepted 20 January 2016 Available online 26 January 2016 Monterey Bay, California (CA) receives nutrients from multiple sources, including river discharge, upwelling of deep water, and submarine groundwater discharge (SGD). Here we evaluate the relative importance of these sources to Northern Monterey Bay with a mi...
متن کاملSubmarine groundwater discharge of nutrients and copper to an urban subestuary of Chesapeake Bay (Elizabeth River)
We investigated the role submarine groundwater discharge (SGD) plays in the delivery of nutrients and copper to the Elizabeth River (Virginia) estuary, a major subestuary of lower Chesapeake Bay. Using an approach based on radium isotopes, we concluded that two distinct sources of groundwater were equally impacting the estuary: a surface (marsh) aquifer and deep aquifer source each with a uniqu...
متن کاملSpatial distribution and budget for submarine groundwater discharge in Eckernförde Bay (Western Baltic Sea)
Submarine groundwater discharge (SGD) from subseafloor aquifers, through muddy sediments, was studied in Eckernförde Bay (western Baltic Sea). The fluid discharge was clearly traced by 222Rn enrichment in the water column and by the chloride profiles in pore water. At several sites, a considerable decrease in chloride, to levels less than 10% of bottom-water concentrations, was observed within ...
