On the Removal of MT Signals from SBL Data

Abstract: When performing a seabed logging (SBL) survey during a period of high magnetotelluric (MT) activity, it is not uncommon for MT signals-due to their highly variable and nonstationary nature-to significantly reduce the quality of SBL data. In the most dramatic instances, this can create the need for retowing some SBL lines at a high additional cost. We propose and describe a simple method to partially remove MT signals that may be superimposed to SBL data acquired during periods of high MT activity, and subseque… Show more

“…In conventional CSEM data acquisition it is recognized that the MT noise is correlated over large distances. De la Kethulle de Ryhove and Maaø (2008) described the use of a remote reference node to estimate this spatially‐correlated noise well away from the source.…”
