EMD is a signal processing technique useful in study non-stationary physical processes. In this study We expanded EMD tool introducing the weighted mode EMD. High resolution seismic data are optimal filtering adopting the weighted mode EMD. Results are used to image complex geology in Gulf of Mexico continental shelf. Seismic anomalies might suggest presence of gas hydrates buried sediments.
