JPL Greenland Moulin Exploration Probe
- Monday, 06 July 2009
A probe was designed to investigate the moulins (melt water drainage channels on an ice cap) and ice-hydrology interaction in the Greenland Ice Cap. By using commercially available components, the strong and reliable system has been developed that has a high-definition video recording element, is lightweight, and has buoyancy that is easily adjustable for neutrality or to be slightly positive in the water, enabling different deployment scenarios.
The system is in a small (20×20×20-cm), watertight Lexan box that can follow the water into the ice, but then be retrieved by tether. The system is rated for a water depth of 100 meters. The purpose of this system is to gain understanding about the interaction between the ice and the melt water and how this interaction may be accelerating the melting of glaciers and, in general, an overall better understanding of global warming.
