In the Physical Acoustics Laboratory (PAL), we are interested in extracting information from scattered waves in heterogeneous media. Indoors, these waves are of ultrasonic frequencies, excited and detected with lasers. Outside, our waves are in the seismic frequency band.

Seismic Station AUCK is our home-built TC1 seismometer on campus

As our wavelengths span orders of magnitudes, so do our applications. Outside, we study CO2 sequestration and geothermal exploration, as well as micro-seismicity for fluid reservoir characterization. In the laboratory, we do rock physics in collaboration with the PORO lab, ice core tomography, and medical imaging.

News & Announcements

  • Resonance on ice Today, research in collaboration with the University of Otago was published in The Cryosphere. In it, we monitor the temperature dependence of the elastic properties and the attenuation constant of ice, based on resonance measurements in the Physical Acoustics Lab. In the image at the top you can see how resonant peaks shift and attenuate ...
  • Josiah became a father (for the second time) With great joy we share  the news that Josiah (MSc alum and current PhD candidate in the Physical Acoustics Lab) and Kinga are now the proud parents of  two daughters! Xylia’s new little sister is named Nadzieja.
  • More recognition for Sam’s research Already on a roll, Sam Hitchman entered the Faculty of Science postgraduate poster competition. His poster on laser ultrasonic investigations of apple ripeness was awarded “high distinction.” We congratulate Sam with this top-8 finish in a field of 65 posters in contention!
