Characteristics of the Ground-Water Seepage into Great South Bay

Abstract

from the abstract, "The water quality and salinity in Great South Bay represent a balance between the amount of seawater that enters the bay through its inlets and the amount of freshwater that is supplied from Long Island. Streamflow accounts for most of the freshwater supplied to the bay. This source is routinely gaged by the U.S. Geological Survey. The second largest contribution is the submarine outflow of ground water across the bay floor. Direct measurements of this source are reported here. This is the first such study of the submarine outflow into Great South Bay or, indeed, into any coastal body of water."
