Abstract
WE BELIEVE IT MAY BE POSSIBLE TO DETECT INTERNAL WAVE REGULARITIES GENERATED BY MOVING SUBMARINES BY USING NON-ACOUSTIC MICROTHERMAL ARRAY MEASUREMENTS SENSITIVE AT THE 0.001 DEG C LEVEL OR BELOW. TYPICALLY OCEANIC MICROTHERMAL TEMPERATURE GRADIENT MEASUREMENTS ARE COMPUTED AS SMALL DIFFERENCES (...) BETWEEN THERMISTOR MEASURED TEMPERATURES T(2) AND T(1) AT TWO DIFFERENT LEVELS ON A TOWED ARRAY. ANY ABSOLUTE ERRORS IN THE MEASUREMENT OF THE LARGE INPUT TEMPERATURE (T2) AND T(1) ARE THUS TREMENDOUSLY MAGNIFIED IN .... WE PROPOSE INSTEAD A COMPLETELY DIFFERENT TECHNIQUE WHICH INTRINSICALLY MEASURES SUCH SMALL ... DIRECTLY RATHER THAN BY SUBTRACTION OF TWO LARGE INDIVIDUAL SEA TEMPERATURE MEASUREMENTS FROM VERTICALLY SEPARATED THERMISTORS. IN THE PHASE I RESEARCH WE WILL DEMONSTRATE BOTH THEORETICALLY AND VIA A LABORATORY PROTOTYPE DEVICE THAT OUR PROPOSED OCEAN MICROTHERMAL SENSOR TECHNIQUE HAS A READABLE RESOLUTION AND STABILITY OF 0.0001 DEG C AND A ABSOLUTE ACCURACY IN ... EXCEEDING 0.0001 DEG C AT A 10 HERTZ OR FASTER DIGITAL SAMPLING RATE.
