Abstract A survey of the chemical composition of five coastal dune ponds on the Outer Banks, North Carolina, showed the ponds to be more similar to underlying groundwater than to dilute seawater or average river water. With a mean total ionic content of 3.14 mmol l−1 the ponds were decidedly fresh. Variations in chemistry between the ponds resulted from physiographic association with leached or unleached dunes, and from different soil types in the pond basins. Near isothermal conditions were found in all but one pond. Oxygen levels were reduced at depth in every pond (10 to 25% saturation). Comparative data show the influences on major ion chemistry in these ponds to be substantially different from those of some other coastal dune waters.
