Marine remote sensing of hydrocarbons based on EM-soundings does not work very well in case of shallow waters due to strong airwave contributions. In this paper we investigate a multi-component signal processing approach which has the potential to attenuate such airwaves. Tests of the technique employing synthetic North Sea data gave significant improvements.doi:10.2529/piers060822070325 fatcat:zkljnkiphbhaldwx6ejlcve5bi
