| Abstract: | SUMMARY. 1. An inexpensive pumping and reservoir system has been developed for circulating water over intact sediment cores. The system facilitates both measurement and manipulation of supernatant properties and flow velocities.
2. The apparatus has been used to evaluate the effect of flow velocity and pH on nutrient exchange at the sediment-water interface. |
