Fig. 7: Example for estimating the motion of a reflection patch of ~200 m in length on line C15.
From: Intensifying stratified turbulence and mixing towards the oceanic submesoscale front
a Pre-stack seismic reflection data for each shot (sh) along the streamer channels (ch) in a time (depth) window of 0.08 s (60 m). b Instantaneous amplitudes showing the reflection anomaly in (a). c Summation of the instantaneous amplitudes used for tracking the energy peak for each shot. The dashed lines are the alignments of the reference moving velocities. d Spatial vespagram for searching the optimal velocity of the reflection patch by slant stacking. e Seismic image showing the concerned reflection patch (black box) and its moving direction (cyan arrow). The upper left and lower right subsets are close-ups of the seismic reflection patch and its instantaneous amplitude, respectively.
