A monthly open webinar series in which the Flagship’s researchers offer snapshots into their current work and activities within the FAME - Flagship of Advanced Mathematics for Sensing, Imaging and Modelling.
This webinar will be presented by Professor Gregor Hillers, from the University of Helsinki, on the topic:
A seismic experiment to image and monitor the lake ice dynamics and properties of the boreal Lake Pääjärvi.
Professor Hillers’ DYNALake project explores a novel approach for quantifying methane ebullition from a boreal lake using passive seismic tomography of the lake ice cover together with interdisciplinary observation methods. The basis for this and many other non-invasive monitoring and imaging applications is the analysis of elastic waves that is used to estimate properties of the propagation medium. The DYNALake centerpiece is a dense array of 200 seismic geophones that we deployed in February 2025 on the ~30 cm thick ice sheet of Lake Pääjärvi some 100 km north of Helsinki.
Welcome!
