Overview of the 250 mobile seismological stations (Fairfield nodes) received in Sveagruva (Svalbard - Norway) for deployment as part of the Icewaveguide project.
The sea ice is disappearing with global warming, and if the trend is clear over the last few decades, scientists are still wondering about the speed of this disappearance, which seems much greater than the models predict.To better assess the quality of the polar ice (its thickness, its degree of fra...

The sea ice is disappearing with global warming, and if the trend is clear over the last few decades, scientists are still wondering about the speed of this disappearance, which seems much greater than the models predict.To better assess the quality of the polar ice (its thickness, its degree of fracturing), a team of scientists conducted a reconnaissance and test expedition in February and March 2019. The objective was to listen to the natural vibrations of the ice pack to deduce its mechanical characteristics (thickness, solidity, etc.). A pilot site was identified in Svalbard, at 78° north latitude, as close as possible to the Arctic pack ice. 250 seismic sensors (seismometers) from the SisMob mobile instrument park of Résif were installed there for one month to record the vibrations and murmurs of this small ephemeral pack ice (it forms only a few months per year) in the Sveagruva fjord.This picture shows the inventory of the stations and their preparation for deployment on Lake Vallunden (Svalbard - Norway) during Icewaveguide project.During the transport phase the nodes are switched off. Once on site they must be ""reactivated"". This step is done thanks to the yellow tablet that can be seen on the ground. It is connected to the nodes via the cable and allows the dialogue with the nodes. The first action carried out is therefore the starting of the nodes, an action which will allow the reception of the satellites necessary for the good synchronization of the data.
