Abstract：Before designing the airgun array in transient zone of shallow sea, it should investigate geophysical feature of explored targets and lithology of sea bottom and select the appropriate sink depth of airgun array, working water depth of airgun and size of airgun array according to depth of water. After that, using Nucleus airgun array simulating software to simulate the array, determine several airgun arrays by bob ratio, peak-to-peak value and frequency feature and define the final airgun array by experiments. It is shown by practices of two seismic objects: A and B that the characters of water area and geophysical feature of layers in the objective zone are fully considered in the designed airgun array, which achieved good prospecting effects.
