Two main seismic sources were shared by all of the systems described above. The first, and most extensively used source, was a vibroseis truck shipped over from the University of Calgary and the second was a well traveled 'thumper' from Otago. Both sources were used daily for shooting either into the various arrays of 'Cubes' and Aries lines or the downhole instruments from different locations throughout the valley. The vibe truck alone did roughly 9000 'sweeps' during the two weeks of shooting.  Vic students Danielle Lindsay (summer student with newly coronated head of school John Townend) and Chet Hopp (PhD, Geophysics) were on hand to provide much needed muscle and moral support. Thier responsibilities were varied but mostly consisted of deployment, maintenance and retrieval of the various above-ground seismic systems. In particular, the Aries II system from Calgary required multiple days to lay out the kilometers of cable, batteries and geophones as well as regular daily maintenance and troubleshooting.
