|Modification of the PICO 5.2-inch Ice Coring Drill to Sample Rock at the Base of Glaciers
|Bruce R Koci
PICO has developed a deep ice coring drill designed to take a 5.2-in diameter core in a fluid-filled (n-butyl acetate) hole. It is desirable that this drill, or an alternative method, be capable of sampling to rock contact and beyond to ascertain that the ice-bedrock interface has been reached.
