Abstract : A method for sampling toxin flux rates across a benthic boundary relies upon deploying an apparatus having a frame which houses a container having an open bottom for isolating a volume of fluid above a benthic fluid boundary. A sampling system periodically samples and stores samples of the isolated fluid and an oxygenation system maintains a constant dissolved oxygen level within the container. The device is then retrieved and the samples analyzed. In this way, the toxin flux rate across the fluid boundary may he determined.
