Abstract : Temperature-jump measurements in sea water over the time domain 0.00001 to 0.01 sec reveal a single relaxation of 0.00015 sec at 9.7C, which appears to correspond to the approximately 1 kHz relaxation found from long range sound propagation. Laboratory measurements indicate the relaxation to originate from boron with the B(OH)3 - B(OH)4 - equilibrium the likely relaxing process. (Author)
