Entry ID: Hot_Water_Drill_Systems_NSF_PLR_1146554_1.0


Summary
Abstract: A new, clean, hot-water drill system (HWDS) was developed by the ANDRILL Science Management Office, University of Nebraska-Lincoln, for use in the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project to gain access to Subglacial Lake Whillans (SLW) in January 2013 beneath ~800 m of ice in West Antarctica (84.240 S, 153.694 W), as well as at the grounding zone (GZ) of the Ross ...

Purpose: The primary goal of this project was to describe the overall design of the WISSARD (Whillans Ice Stream Subglacial Access Research Drilling) Project?s hot water drill system (HWDS). The UNL design of WISSARD HWDS is comprised of the following primary modules and containers: (1) a Melt Tank (MT), (2) a 3700 gallon capacity Water Supply Tank (WST), (3) a Water Filtration and decontamination Unit ...

Quality This is raw data concerning the drill system parameters used during the drilling at each site where the WISSARD hot water drill was used to provide an access hole through the ice. The available data include: (1) date and time stamped entries in the drillers logbook, with relevant comments, which can be combined with date and time-stamped data collected from select drill system sensors; the sensor data record: (2) the drill output water flow rate (in units of gallons per minute, gpm), (3) the drill output water pressure (in units of pounds per square inch, psi), and (4) the head measured in the borehole by a pressure sensor located at the borehole submersible pump (in units of meters).
