PERMIT ISSUED UNDER THE ANTARCTIC ENVIRONMENTAL PROTECTION ACT 1994

26. Permit No. 98/02 issued 30/10/98 to CRP approved (Appendix 3):

a.	Controlled access to Granite House (refer Para 22),
b.	Use of explosives to cut the sea riser casing at the sea floor on completion of drilling,page 7
c.	Use of explosives under the sea ice to carry out vertical seismic profiling (VSP) as part of scientific down-hole logging.

27. One explosive device - a Colliding Detonator Cutter - was used to successfully cut the casing at sea floor (178m) to enable the rest of the sea riser to be recovered. At the surface the explosion was detectable only as a 'pinging' sound transmitted up the casing pipe.

28. Twenty four explosive charges were safely and successfully fired as part of the VSP experiment on 30 November. The Science Support Manager who was responsible for this, had ensured no marine life, namely seals, was in the area at the time of the explosions. Refer to his EOS Report for more detail.
