Figure F1. A photomosaic of the hard-rock base at Hole 735B installed during Leg 118. The smaller image to the left shows the hole itself through the open throat of the base. The base is 17 ft by 17 ft by 11 ft high. The mosaic was constructed from frames grabbed from a video sequence obtained near the seafloor using the Canadian ROPOS in the spring of 1998. The survey was carried out using the vessel James Clark Ross of the British Antarctic Survey. The figure was provided courtesy of the expedition's co-chief scientists, H.J.B. Dick, P.T. Robinson, C. MacLeod, and S. Allerton.
