Abstract：It is necessary to investigate water depth,sea floor and tide before seismic field work in shallow waters.Water depth is directly refated to seismic streamer depth and receiving effect,and tide data can be used to choose optimum shot time and to calculate feathering angle(i.e.,the angle included between seismic line and seismic streamer).In shallow waters of North Bay,quite good seismic data can be obtamed using the field method in which 36-trace spread whose total length is 2Km and 36-fold multiplicity are used,and in which seismic streamer and air gun with the capacity of 1930 cubic inches are put at the depth of 6m.
