Abstract:

The WISSARD hot water drilling system includes a water treatment system designed to remove micron and sub-micron sized particles (biotic and abiotic), irradiate the drilling water with germicidal UV radiation, and pasteurize the water to reduce the viability of persisting microbial contamination. The purpose of this system is to generate and deliver a clean and reliable supply of hot water for drilling boreholes through the ice sheet and into Subglacial Lake Whillans (SLW) and the interconnected subglacial drainage system. Figure 1 provides a schematic of the drilling system components, together with the location of selected sampling ports used for collection of the water for microbiological analysis.
