Extensive measurements in the Atlantic Ocean 4 degrees C have shown the attenuation of sound below 10 kHz to be anomalously high. In order to determine the temperature dependency of this anomaly, a similar experiment has been conducted in the warmer water 22 degrees C of the Red Sea. The results show a shift in the apparent relaxation frequency from the 1 kHz observed in the Atlantic to 1.5 kHz, resulting in higher values of the attenuation coefficients in the range 1-6 kHz. The computer activation energy is comparable with that expected for hydrogen bonding. Author
