Comments	Complete unit operating is ~1000 lbs. Heaviest component is winch (on sled) at ~500 lbs.	Shipping weight and cube listed above includes all spares, tools, two generators and shipping cases.			Complete unit operating ~800 lbs. Heaviest component is the winch (on sled) 400 lbs. Winch control box 250 lbs.	Shipping weight includes generator and 100 or 200 meter winch, depending on the required depth; complete operating weight is 800-1700 lbs; uses 4-Inch Drill system winches	Shipping weight listed above includes all spares and shipping cases. For ultra-lightweight deployments, where spares and shipping cases can be left at a base camp, the weight of the winch, tower, one control box and one sonde is estimated at 604 lbs.	Operable in ambient temperatures down to -25°C. A back-packable tent for housing drilling operations is also included.
Restrictions			* The depth capability of the BID-Deep is largely influenced by site/ice characteristics. The current equipment is likely reaching its operational limits and assuring acceptable core quality at depths of 200 m would require a re-design of the system. * IDP is discussing with the science community several approaches for drilling good quality ice core in blue ice, which may include design and fabrication of a modified BID or the development of a large-diameter thermal drill.

Comments	Intermittent ice coring possible by replacing non-coring bit with core barrel assembly
Restrictions	In light of use of a drilling fluid, it is critical to select sites where the ice is frozen to the bedrock and is free of cracks and/or the presence of liquid water. Any voids within the ice or near the bed will result in a pressure drop and loss of fluid flow and would halt drilling. In addition, site selection should favor areas where the bed geometry and ice flow minimize pre-existing stresses present in the ice, reducing the risk of hydro fracture during drilling.
