Hot-water rescue ice drilling system to recover subglacial lake exploring sonde: General concept
Autonomous sondes are used to study the Antarctic subglacial environment, yet they risk of being frozen in ice due to heating failure. To recover an accidently frozen sonde this paper describes a concept for a hot-water rescue ice drilling system. A special hot-water drill tool was designed to drill downward along the cable/sonde and melt surrounding ice. Theoretical estimation indicated the power system needed to provide hot water at a flow rate of 25 L/min and a pressure of more than 4.2 MPa to release the sonde at ice depth of 500 m. Laboratory testing and field testing near the Chinese Zhongshan Station in Antarctica demonstrated rationality of the concept. Potential risks were estimated and corresponding solutions presented. The hot-water rescue ice drilling system mentioned in the paper provides a safety guarantee for subglacial lake successful exploration, furthermore supports more ideas for future ice sheet exploration.
期刊介绍：
Polar Science is an international, peer-reviewed quarterly journal. It is dedicated to publishing original research articles for sciences relating to the polar regions of the Earth and other planets. Polar Science aims to cover 15 disciplines which are listed below; they cover most aspects of physical sciences, geosciences and life sciences, together with engineering and social sciences. Articles should attract the interest of broad polar science communities, and not be limited to the interests of those who work under specific research subjects. Polar Science also has an Open Archive whereby published articles are made freely available from ScienceDirect after an embargo period of 24 months from the date of publication.
