(a), (b) Detail of Line KIN_054 seismic profile and (c), (d) corresponding heat flow plot; location in Fig. 4. Yellow arrowheads denote the BSR. Red arrowheads in (b) indicate the relic and migrated BSRs caused by erosion. Red lines and orange translucent zone in (a) and (b) indicate the interpreted faults and cover sediment, respectively. Red and blue arrows in (c) and (d) denote local increasing and decreasing trends of heat flow, respectively. Gaps in BSR-derived heat flow data exist in (d) because heat flow cannot be estimated where the BSR is absent or weak. Note that the high heat flow anomaly around 50 km in (b) corresponds to a feature in the seafloor topography
