Abstract

Techniques and apparatus inhibit, limit, or remove biofouling and certain inorganic accumulations, to increase the longevity of accurate in-situ oceanographic and other underwater measurements. The invention deters formation of an initial bacterial layer and other precipitation, without harming the environment. The invention integrates an ultrasonic source (24) into a sensor or other device, or its supporting structures. The ultrasonic source vibrates one or more critical surfaces (12) of the device at a frequency and amplitude that dislodge early accumulations, thus preventing the rest of the fouling sequence. The ultrasonic driver is activated for short periods and low duty cycles, and in some cases preferably while the device is not operating.
