Reducing the effects of fouling on chlorophyll estimates derived from long-term deployments of optical instruments
Two methods to alleviate the problem of fouling of moored flow tube optical instruments are presented. A chemical method diffuses a concentrated solution of bromine into the flow tube between sampling periods, creating a toxic environment for microorganisms. An optical method removes a baseline valu...
