Sound Propagation South of Martha's Vineyard.
An experiment was performed south of Martha's Vineyard, Massachusetts, on the Long Island platform using an embedded triaxial geophone and a colocated hydrophone as a receiver. The data shows low propagation loss even with a strong negative sound velocity gradient in the water. The signals from...
