Figure F2. This 3.5-kHz echo sounder recording shows that the seafloor dips smoothly ~6 m from the junction box to the drill site (proposed Site H2O-5). One subbottom horizon at ~9 m is fairly uniform throughout the area. Based on drilling results, this is a mid-sediment reflector. A second reflector at ~30 m below the junction box can be associated with basaltic basement although it appears only occasionally in the record. PDR = precision depth recorder.
