Behavior of a deep hole drilled in ice at Vostok Station

A coring hole (5G) was drilled at Vostok station down to the depth of 2500m using an electro-thermal drilling system. Relationships between ice core, hole diameters, and drill speed are presented. The hole was only partially filled with fluid (of density of 860kg m^<-3>) so that ice pressure w...
