Abstract
A method for removing the air wave effect from offshore frequency domain controlled source electromagnetic survey data. The region of interest is modeled with () and without () a top air layer. The electromagnetic field due to the source is computed at the survey receiver positions for each source position for both models. The difference between the fields computed () from the two models is the air wave effect, which is then subtracted () from the field data for the corresponding source-receiver geometry.
