Abstract
Arete will develop a non-fouling, robust, monolithic, sensor package that will yield accurate salinity calculations from temperature and conductivity measurements. The sensor comprises a unique conductivity cell, a thick-film thermistor, and an embedded ultrasonic cleaning device used to remove all incipient detritus from the sensor head. The temperature and conductivity measurements will be programmable for intervals varying from sparse to continuous measurements in order to conserve power and to suit applications requirements. The frequency and amplitude (and the resulting surface acceleration) of the ultrasonic oscillation in the integral cleaner will be selected to disrupt and dislodge the smallest unicellular organisms that are at the vanguard of biofouling. The cleaner will be activated for only a few short intervals each day to disrupt the early adhesions of fouling organisms. The clean sensor surface will ensure proper sensor accuracy before recalibration for at least one year.
