Development of a high resolution ice echo sounder for Arctic ice sheet

An ice core experiment conducted jointly by Japan and Canada was initiated in the Arctic region three years ago. It is now planned to drill the ice cap in the Canadian Arctic which would yield ice samples that have been in existence for hundreds of years. To start this study, ion concentrations, micro particles chemistry and the electrical properties of the ice and melt water having been measured to reconstruct paleoclimate/environment in the Arctic region. In order to support this program, a new type of echo sounder has been developed by Communications Research Laboratory (CRL). It has a capability of detecting the structure of ice beneath a surface with high resolution.<
