Waves and Wave-Based Imaging in Virtual and experimental Environments

ESR3.3: Gil AVERBUCHSolid earth, oceans and atmosphere

My name is Gil AVERBUCH and I am a PhD candidate at the department of applied geophysics in TU Delft ,The Netherlands. I did my undergraduate degree in geophysics and my M.Sc in geophysics and atmospheric sciences. Both in the department of Geosciences in Tel Aviv University, Israel. My main interest is probing the atmosphere using infrasound (low frequency sound waves in the atmosphere) signals, infrasound wave propagation modeling and earth-ocean-atmosphere coupling i.e. the relationship between seismic waves, hydro-acoustic and infrasound waves. Since infrasound waves are sensitive to variations in the atmosphere, their detection can be used to probe the atmosphere with interferometric techniques. In order to study earth-ocean-atmosphere coupling I am using both numerical simulations based on finite differences and finite/spectral elements for full wave modeling and ray tracing models.

It has been shown recently that elastic waves from underwater sources (earthquakes, volcanos) generate airborne acoustic signals that can be measured by the global infrasound network. The student will explore this newly discovered phenomenon in detail.

Expected results:

The nature and global distribution of underwater infrasound sources will be determined for the first time. To characterize the sources, additional seismological and hydro-acoustic measurements will be analysed. Infrasound recordings from these sources will be used jointly with microbarom/seismic data to map the stratospheric wind and temperature structure through interferometric techniques. The spatial and temporal resolution will be much higher than that achieved by satellite observations, which only measure temperature.
