Amery Ice Shelf - hot water drill borehole, 2005-06 - AM04 caliper data

See Readme file . data collected as header, depth (m), diameter (cm) Borehole diameter was attempted to be wide enough to allow passage of a large ADCP instrument . this worked well in the upper parts of the borehole but not at great depth in the permeable marine ice layer (530-600 m). Note - depths...

Description
Summary:See Readme file . data collected as header, depth (m), diameter (cm) Borehole diameter was attempted to be wide enough to allow passage of a large ADCP instrument . this worked well in the upper parts of the borehole but not at great depth in the permeable marine ice layer (530-600 m). Note - depths and altitudes provided in spatial coverage are referenced back to sea level. The minimum depth asl refers to the height of the ice surface. AM04 borehole drilled January 2006. Profiling measurements conducted to test borehole diameter integrity.
