Fig. 3. Cross sections below Pit 3 showing the gentle parabolic trajectory of Boreholes (a) MH-1, (b) MH-2, (c) MH-3, (d) MH-4, and (e) MH-5 from Site 1 that were sampled in this study. Each projection is along an individual bearing shown in Fig. 2b. Seamist labels mark the maximum deployment of dedicated flexible liner systems in each borehole (MH-1 was not sampled). Stations 1 and 2 in Borehole MH-3 depict locations of gas sampling and testing portholes during the first Seamist deployment.
