Data-adaptive global full-waveform inversion

In this video Dr. Sölvi Thrastarson presents a novel approach to global-scale full-waveform inversion (FWI) that can reduce computational cost by over an order of magnitude, compared to previously published methods, without sacrificing physical and mathematical rigour. This is based on data-adaptation, and thereby application-oriented specialization, on two complementary levels.

hey, old friend! May you have a promising future in the ice world!

Dear Dr Sölvi. Could these results indicate that the Hollywood blockbuster The Core was ahead of its time?
