Twice Daily, Down the Race

A Dairy Herd's Walk to Milking as a Repeatable Seismic Source for Imaging a Buried Palaeochannel

A research poster from the School of Emergent Priorities records 42 passes of a 412-cow dairy herd along its race to milking on a 96-geophone line and stacks the footfall into Rayleigh-wave dispersion spanning 5.5 to 31 Hz, against 12 to 23 Hz from overnight noise on the same line. The herd-derived shear-wave section agrees with a sledgehammer reference to within 6% to 12 m and resolves a slow lens beneath chainage 64 to 122 m, which a cored hole confirms as a sandy-gravel palaeochannel fill with its base at 8.7 m.
