We now have a well cavity, and well pump installed. To make the cavity 80m below the surface of the ice shelf the hot water drillers use a drill attachment called a ‘Christmas Tree’ that sprays water in multiple directions. The well pump is vital, circulating water through the system, pumping an endless supply to drill our main borehole right through the 580m ice shelf. It’s heavy piece of kit, with numerous cables and hoses. It was all hands on deck to ensure a safe and successful install! (for more images see Gallery)
