OBC Surveys

The OBC cable was placed on the ocean floor at a depth of roughly 450 m. Multicomponent phones were spaced every 12.32 m along the entire length of the model. As the model is 2D only the x and z components of the wavefield were measured. Marmousi2 OBC survey data should have header information configured as shown in table 4.
