Iodine-dispensing antifoulant implemented with dispensing shutter

Sensors, such as optical sensors and other sensors used in an aqueous environment are protected from biological contamination by applying a biocide behind a shutter. The shutter is capable of covering a subject portion of the sensor or surrounding mounting surface adjacent the sensor in at least a semi-sealing manner. A well or reservoir forms a chamber in the shutter that is capable of holding a biocide having a limited water solubility and a low environmental toxicity in the aqueous environment, for example, anhydrous iodine crystals. The reservoir is in communication with the portion of the sensor while positioned against the portion of the sensor or surrounding mounting surface adjacent the sensor.
