ICEWAVEGUIDE

Obtaining insights about ice mechanical resistance and its level of structural damage would be a substantial contribution to current knowledge, for example for multi-physics modeling purposes. This information could be integrated radar- or sonar-based applications as well. Also, it should be emphasized that with the present methodology the measure is continuous for as long as the seismic array is left to record ambient noise. Note that associated costs are very reasonable. Current daily price for renting a 1-component seismic sensor is $1.5, making the total price of $1500/day for the experiment at Vallunden Lake. We anticipate that this cost should go down significantly in the close future thanks to constant technological advances. Indeed, in the last 10 years this cost has gone down by a factor 10 and this tendency should continue. Moreover, one of the conclusions of the ICEWAVEGUIDE project is the optimal number of sensors to use for a measurement campaign. This number should be significantly less than on Vallunden Lake where a very dense array will be used, precisely to provide and answer to this question. Hence, from what precedes, we expect the daily cost associated with sensors rental for future experiments to be very low (less than $1000/day). Compared to alternative methods such as an AUV or radar antennae currently used in glaciology, a financial gain is expected.
