EVALUATION OF METHANE CONCENTRATION IN WATER COLUMN, IN METHANE BUBBLE DISCHARGE AREA

摘要

FIELD: physics.;SUBSTANCE: acoustic signal is emitted toward sea bottom. Signal of sound reradiation from water column is received. Gas flares are isolated from receive signal. Gas flare inclination is used to evaluate the stream velocity profile and direction. Density of gas flare sources on sea bottom and methane flow direction in water for every flare are calculated. Obtained data allows the determination of methane concentration in water column in the area of methane discharge.;EFFECT: higher efficiency and accuracy of evaluation.;1 dwg
