Knowledge of the sea surface and reflection coefficient allows approximate correction of the prediction errors. Based on a novel dual‐sensor towed streamer acquisition we propose a multiple prediction approach from the down‐going vertical velocity field and up‐going pressure field. This approach handles the sea surface variations implicitly and may reduce bad‐weather‐related acquisition downtime.Permalink: https://doi.org/10.1190/1.2792994FiguresReferencesRelatedDetailsCited ByPrediction of signatures of airgun arrays using dual near‐field hydrophones5 March 2019 | Geophysical Prospecting, Vol. 67, No. 6Migration of primaries and multiples using an imaging condition for amplitude-normalized separated wavefieldsAlba Ordoñez, Walter Söllner, Tilman Klüver, and Leiv J.
