THE flow of ground water directly into the coastal ocean has been studied previously by in situ measurements, seep meters and diffusion gradient models1. Although these techniques provide ample

Tracer studies reveal that submarine groundwater discharge provides globally important fluxes of nutrients, carbon, and metals to coastal waters.
Groundwater and pore water inputs to the coastal zone
Both terrestrial and marine forces drive underground fluid flows in the coastal zone. Hydraulic gradients on land result in groundwater seepage near shore and may contribute to flows further out on
Quantifying submarine groundwater discharge in the coastal zone via multiple methods.
Measurement of 223Ra and 224Ra in coastal waters using a delayed coincidence counter
We describe a nuclear detector system for measuring low activities of 223Ra and 224Ra in natural waters based on an original design of Giffin et al. (1963). Samples are obtained by adsorbing 223Ra

Coastal surface waters in the South Atlantic Bight contain elevated activities of 223Ra (t1/2 = 11.4 days) and 224Ra (t1/2 = 3.66 days). These elevated dissolved activities are due to continual input
