a Seismic reflection images of the RK02 profile showing magmatic intrusion breaching the seafloor. Here, unlike the RK01 profile (Fig. 5), ~ 1-km-wide transparent bodies indicating volcanic conduits penetrate the shallow crust or sedimentary layers to form obvious volcanic mounds on the seafloor (b, c). They are also accompanied by small fragments of seismic reflectors at their roots which are interpreted to be intruded sills (small blue arrows)
