description |
Dans le cadre de l’intégration aux dispositions européens EPOS, Résif s'est transformé en octobre 2023 en Epos-France, une nouvelle infrastructure de recherche aux contours thématiques plus larges et en accord avec ceux de sa grande sœur européenne. 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 one of the one hundred autonomous seismological stations (Fairfield nodes) belonging to the national park of land mobile seismological instruments (Sismob) which were installed for a measurement campaign on the frozen lake of Vallunden (Svalbard - Norway).The ice was first excavated using a specific tool, designed in the laboratory and made by a subcontractor. This ice-cutting tool made it possible to quickly dig a hole the size of the nodes, thus facilitating their positioning.Sismob is one of the specific actions of the French Réseau sismologique et géodésique français Résif, a national research infrastructure dedicated to the observation and understanding of the internal Earth structure and dynamics. Résif is based on observation networks of high technological level, composed of seismological, geodetic and gravimetric instruments deployed densely throughout ... |
