Abstract
The present invention concerns a method of processing marine data and a processing apparatus for the same. The processing method according to the present invention comprises obtaining a per-profile initial total magnetic anomaly from raw data; obtaining a filtered total magnetic anomaly by filtering out a high-frequency component from the initial total magnetic anomaly; obtaining a reference corrected total magnetic anomaly by correcting the filtered total magnetic anomaly with respect to a reference total magnetic anomaly; and showing a per-profile total magnetic anomaly using the reference corrected total magnetic anomaly.
