The U.S. National Science Foundation Ice Drilling Program (IDP) was established by the National Science Foundation (NSF) to lead integrated planning for ice coring and drilling and provision of drills and drilling services.

2022年2月23日 · Taking its power from Earth’s core, geothermal energy is generated when hot water is pumped to the surface, converted into steam, and used to rotate an aboveground turbine. The motion of the...

2017年1月20日 · Hot-water drilling provides a rapid and relatively inexpensive method for drilling holes in warm and cold ice. The major problem facing a driller in attempting to drill a bore hole in cold ice to great depths is that the hole will refreeze rapidly over time.

Hot-water drills (HWDs), with their inherent speed, offer the only feasible alternative for accessing deep aquatic subglacial environments, using and recycling multiple times the water melted from the surrounding ice sheet to create access holes that are water filled.

The IDP Small Hot Water Drills (SHWD) use hot water to create shallow holes in ice. They are non-coring and are typically used to produce holes 100-200 mm in diameter down to a maximum practical depth of 60 meters.

British Antarctic Survey has developed and applied the technique of hot-water drilling to provide subglacial access for more than 40 years. This technique enables direct observations and sampling of the ocean and seabed beneath floating ice …

To be able to drill nonetheless, researchers have a trick up their sleeve: melting the water they need for drilling right on top of the ice shelf. In the following, AWI engineer Jörg Brozek explains in detail how the process works. First of all, we prepare the starting water (image 1).

2019年2月7日 · Numerous hot-water drills have been constructed by combining water pumps and heating units, with individual specifications matched to achieve certain drilling rates over anticipated ranges of borehole depths, borehole widths, and ice temperatures.

The IceCube Drill is a specialized hot water drilling system used to create deep boreholes in the Antarctic ice to deploy and maintain the sensors of the IceCube Neutrino Observatory, enabling the detection and study of elusive cosmic neutrinos.
