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 asl refers to the height of the ice surface.
