A Benthic Chamber for Intensely Metabolic Lotic Systems

We have designed a flow-through benthic chamber that has the desirable characteristics of: simulation of tidal currents, continuous operation, ability to measure photosynthesis, respiration and nutrient exchanges, and maintenance of near-ambient oxygen conditions in a highly metabolic environment.

Description
Summary:We have designed a flow-through benthic chamber that has the desirable characteristics of: simulation of tidal currents, continuous operation, ability to measure photosynthesis, respiration and nutrient exchanges, and maintenance of near-ambient oxygen conditions in a highly metabolic environment. The apparatus is based on a 1.3 m long Plexiglas tunnel, closed at both ends, with both constant circulation and periodic flushing. The results of a 9-month study at one location in Flax Pond, a Long Island, New York, tidal pond, show large seasonal variations, influences of both sunlight intensity and seasonality, and a P/R ratio of less than one.
