Abstract
- To understand the propagation characteristics of the low-frequency band by gas sediments, the
sound source moved from the north to the south. The RLs gradually increased with approach to the hydrophone, and reached its highest level at the closest point of approach (CPA) nearest the hydrophone. The RLs from the CPA to the boundary line separating the gas area decreased with the same slope. However, after the sound source entered the area where the gas layer was present, the reduction ratio of the RLs decreased rapidly, due to the effects of the gas bubbles in the sediment.e closest point of approach (CPA) nearest the hydrophone. The RLs from the CPA to the boundary line separating the gas area decreased with the same slope. However, after the sound source entered the area where the gas layer was present, the reduction ratio of the RLs decreased rapidly, due to the effects of the gas bubbles in the sediment.
