Driller Mike Jayred and science assistant Jacob Ward operate the Blue Ice Drill at Taylor Glacier, Antarctica, during the 2014-15 field season.
The Blue Ice Drill - Deep (BID-Deep) is based on the original Blue Ice Drill (BID) but with greater depth capability.
The BID-Deep system was first tested in Greenland during the 2014 Arctic field season. A 187-meter core was drilled during the 2014 test, with poor core quality witnessed after approximately 140 meters. IDDO engineers subsequently designed less aggressive cutters to help improve core quality at increased depths.
A subsequent test of the BID-Deep system was conducted down to 125 meters at Taylor Glacier during the 2014-15 Antarctic field season. During the test, the quality of the large-diameter core was found to suffer below a depth of 70 meters.
The BID-Deep system was further tested in Greenland during the 2015 Arctic field season using new cutters in an effort to improve core quality at depth. The drill was able to drill to approximately 155 meters using the new step cutters and trying a variety of other techniques before core quality was no longer acceptable.
