Description
Summary:See Readme file . data collected as header, depth (m), diameter (cm) Borehole diameter greatly enlarged at two depths: (a) 60 m at level of sub-surface water well and (b) 376 m where hydraulic connection was first made with ocean cavity beneath shelf (probably through englacial conduits in marine ice layer. Note - depths provided in spatial coverage are referenced back to sea level. The minimum depth of 65 metres asl refers to the height of the ice surface. AM01 borehole drilled January 2002. Profiling measurements conducted to test borehole diameter integrity. AM01b borehole drilled mid-December 2003. No new caliper data collected due to faulty wiring on instrument winch slip ring.
