Fig. 2: Wide-angle seismic data recorded on OBH 502 along profile RFR96-01.
From: Discovery of flat seismic reflections in the mantle beneath the young Juan de Fuca Plate
a The primary seismic phases are direct water wave (P0, magenta), crustal P-wave refractions (Pg, green) and crust-mantle boundary (Moho) P-wave reflections (PmP, orange). The presence of multiples is shown in a dashed green line. The mantle reflection events, the focus of this study, are marked in blue and red arrows. In green arrows, we mark P-to-S converted energy. The black boxes (b) and (c) show the close-up regions on the right focusing on the mantle reflection events (blue and red arrows). Yellow filled red curves indicate seismic waveforms for Pg and mantle reflected waves demonstrating the polarities of the mantle reflections. The bottom panel shows seafloor bathymetry along the line with the location of OBH indicated.
