“…At 0515 h on 20 January 2013, we started a visual and 3.5 kHz subbottom seafloor survey by moving the ship 95 m east of Hole U1415K (see Table T1 and Fig. F3 in the "Bench site survey" chapter [Gillis et al, 2014a]). Unfortunately, the 3.5 kHz pinger ceased working before the survey commenced, but we continued with the visual inspection of the seafloor.…”
