The　dynamic　shear　modulus　G　is　one　of　the　vital　parameters　for　the　dynamic　properties　of　marine　soils　and　is　crucial　for　marine　geotechnical　engineering　design.　In　order　to　investigate　the　G　characteristics　of　various　marine　soils,　a　series　of　resonant　column　tests　were　performed　on　undisturbed　marine　soils　with　various　depths　taken　from　Bohai　Bay,　Yangtze　River　estuary,　and　Jintang　Strait,　respectively.　In　addition,　the　maximum　dynamic　shear　modulus　G(max)　and　strain-compatible　G　of　the　tested　marine　soils　were　compared　with　the　marine　and　terrestrial　soils　from　the　published　literature.　A　remarkable　finding　is　that,　compared　with　terrestrial　soils,　the　marine　soils　in　different　sea　area　present　the　stronger　nonlinear　behavior　with　lower　shear　modulus　due　to　the　special　depositional　environment.　With　the　increasing　of　H,　G　in　each　strain　range　increase,　and　the　dynamic　characteristics　of　the　marine　soils　gradually　transition　from　nonlinear　to　linear,　the　G(max)　and　reference　shear　strain　gamma(0)　value　of　marine　soils　in　different　sea　areas　increases　linearly　with　the　increasing　H,　but　the　G(max)　and　gamma(0)　growth　rate　varied　with　the　sea　environment　and　soil　type.　Based　on　the　quantitative　prediction　equation　of　the　G(max)　and　G　attenuation　relationship　(G/G(max)　similar　to　gamma)　of　various　marine　soils,　a　new　prediction　equation　can　be　also　established　to　predict　G　value　in　different　depth　and　strain　levels　of　various　marine　soils.　The　proposed　equation　are　validated　by　independent　experimental　data　of　marine　and　terrestrial　soils　from　the　literature.　In　this　regard,　the　proposed　procedure　provides　a　significant　advantage　in　the　evaluation　of　dynamic　properties　of　marine　soils　in　practice.
