Explosives.

Twenty four Anzomex P explosive primers (0.5 kg each.) with detonators were fired beneath the sea ice for the Vertical Seismic Profiling experiment on 30 November. Seal observations in the drill site area were made daily from the shift change helicopters and seals investigated if within 2 km of the drill site. Lone seals were noted on 10 November 1.4 and 1 km North West of the drill site but they had left after two days. A single seal was noted on 23 November 0.6+ km south of the drill rig and remained less than 24 hours. All seals did not have ice holes when investigated and were transient. No seals were observed in the drill site area on the 7 days leading up to the VSP experiment.

A explosive cutter was used to sever the sea riser casing at the sea floor in 178 m of water on 01 December.
