Resource Evaluation of Marine Gas Hydrates by Seafloor Compliance

O-05 RESOURCE EVALUATION OF MARINE GAS HYDRATES BY SEAFLOOR COMPLIANCE 1 ELEANOR C. WILLOUGHBY and R. NIGEL EDWARDS Department of Physics University of Toronto 60 St. George St. Toronto Ont M5S 1A7 Canada SUMMARY: Methane hydrate changes the physical properties especially by increasing shear strength of the marine sediments in which it is found. Compliance is defined as the transfer function between the vertical displacement of the seafloor and the corresponding pressure expressed as a function of frequency. Since it is sensitive to the elastic parameters of the underlying sediments particularly the shear modulus it is an apt tool for
