(^_^) 新颖性：The method involves towing a floatation device (107) through a body of water e.g. lake, by a tow vessel i.e. seismic vessel, where the device is coupled to a set of seismic energy sources (119) e.g. air guns. Buoyancy of the device is reduced to cause the device to submerge in response to a navigation hazard i.e. ice by allowing water to enter a set of liquid tight chambers (108 ........ (请QQ直接登录后查看全文)
