LONG-TERM GOAL The long-term goal is to develop an Underwater Intelligent Sensor Protection System (UISPS) to keep underwater radiometers free of algae growth and other contaminants. UISPS will allow long-term autonomous radiometric measurements (in the order of one year), which are not currently possible. OBJECTIVES The objectives of this program were the design and assembly of the prototype, perform preliminary testing in laboratory, debug the system as necessary, and perform testing in an

APPROACH One of the important limiting factors in carrying out long-term measurements underwater is the bio fouling that accumulates on the instrument and corrupts the data. Our approach to designing an instrument capable of long-term measurement is to periodically clean the instrument's sensor window. The cleaning itself is accomplished by mechanical means. The instrument is taken through a cleaning cycle periodically. The logic of the measurement and cleaning cycles is controlled by an on board computer. This provides a means of varying the frequency of the cleaning cycle. The computer also controls the data acquisition.
