Ultrasound Imaging of Ice

Ultrasound measurments on ice.

“Ice cores provide direct information about how greenhouse gas concentrations have changed in the past, and they also provide direct evidence that the climate can change abruptly under some circumstances.” British Antarctic Survey

Our aim is to understand ice anisotropy and its impact on ice flow and stability in predicting future sea level rise. It proposes a new ultrasound method to determine crystal orientation fabric, identifying grain geometry with pulse-echo, without damaging the sample, unlike the current method of using polarised light microscopy.
