Thank you.
Our understanding of low-impact seismic was mainly based on the 1999 program that was undertaken on Sable Island. The sound sources that were used came from two vibroseismic trucks that were barged onto the island. They're about the size of gravel trucks. They emit a sound down through the soil, and then there were geophones on the island to receive them. The trucks were kept to the outside of the island, on the beaches, completely out of the vegetated areas, away from wildlife and vegetation. There was a code of practice put into place.
Zoe Lucas, who is an island resident, and also the head of the Green Horse Society and the leading environmentalist for Sable Island, was involved in that program. They negotiated with Mobil changes to that program. They changed the timing of it to avoid the nesting of endangered species, foaling of horses, pupping of seals. They did it in a non-linear fashion because that's one of the environmental concerns about seismic in the boreal and other ecosystems: it's just done without any thought to the landscape. In this case, it was altered.
So there was a whole range of things that went into putting in place a low-impact seismic program.
