Then place the invasive mint in a slightly smaller pot liner. More info about gravel in bottom of a pot can be found at: Peer reviewed only Published between: A Wiener-Levinson filter adjusts the amplitude and phase of the estimated multiples to match the original data. Accurate seawater velocity is critical important for correct depth migration images since an inaccurate seawater average velocity could result in a predicated target depth error of more than hundreds of meters.
In those circumstances wherein the water bottom is relatively flat, the downward-going reverberation distortion at the source, and the upward-going reverberation distortion at the detector are approximately the same. The water bottom reflectivity that gives the minimum value over the suite of processed traces is determined to give a set of selected reflectivities each of the analysis points within a time window. Optimum parabolic Radon transform parameters derived. The method of claim 1 , wherein separating source-side wavefield into source-side up-going and down-coming wavefield comprising a step selected from: The analysis of the stored values is based upon the following rationale: This multiple model is removed from the original data using Optimum Least-Squares filtering over whole ensemble.

Example gathers prior to radon prior to Pre-STM. Such computer-readable media may include computer storage media and communication media. Combined primary wave response signal at time t 1 has an amplitude of MT 2 , identical to the amplitude of the primary wave response signal in Fig. Subterranean formations to be explored, such as formations and for simplicity, only two are shown and discussed , lie below a body of water The distortion function introduced by a single reflection in the water layer is illustrated by FIGS. Streamer length is 5,m with group interval of
Background of the Art In marine seismic exploration, seismic energy is generated by sources towed behind a vessel. After normal moveout NMO correction, a shot or CMP gather can be thought of as being composed of many different parabolic or hyperbolic events. Drainage of excess water is vital for the health of plant roots.
