In 2002 a devastating oyster parasite (MSX) was found in the Bras d’Or Lakes of Cape Breton. Environmental parameters affecting the transmission and life cycle of MSX are not well understood. However field observations so far indicate temperature and salinity are critical. Wireless sensor technology can provide robust, reliable and near real time field data collection of such parameters. This paper addresses an implementation of wireless sensors for the timely and cost-effective monitoring and dissemination of bio-physical parameters of interest in the Bras d’Or Lakes.
