Improved understanding of current and potential future natural hazards is vital for those living and working in the Arctic
Natural hazards, such as extreme precipitation, snow avalanches and earthquakes, pose a threat to populations and infrastructure across the Arctic. The ice masses of the Arctic present several specific types of hazards, including being the major contributor to global sea level rise through melting and as producers of icebergs presenting a hazard to ships.
The goal is to use data coming from INTAROS to improve understanding of current and potential future natural hazards in the Arctic to help a range of stakeholders to be identified in the project.
Specifically, the work focusses on three areas:
improving avalanche forecasts by improving the forecasts of extreme precipitation events which is an important input to avalanche forecast models. This is done using in-situ snow and meteorological observations.
earthquake hazard assessment by use of the seismological data collected through INTAROS. This data will be used to show the benefits of seafloor monitoring in the Arctic Ocean, both on its own but also when used with onshore monitoring information, for the detection of earthquakes and to the measure of earthquake source parameters.
calculating the amount of ice lost from glaciers either by ice melting or ice breaking off from the glaciers themselves. The aim is to derive the contribution of the Greenland ice sheet and Svalbard glaciers and ice caps to sea level rise, via such melting as well as the solid ice discharge and freshwater inputs to the ocean using INTAROS data. This will done by combining satellite based ice velocity maps, in-situ calibrated surface mass-balance maps and ice thickness datasets.
