Near‐surface environmentally forced changes in the Ross Ice Shelf observed with ambient seismic noise
Near‐surface environmentally forced changes in the Ross Ice Shelf observed with ambient seismic noise
Continuous seismic observations across the Ross Ice Shelf reveal ubiquitous ambientresonances at frequencies >5 Hz. These firn-trapped surface wave signals arise through wind and snowbedform interactions coupled with very low velocity structures. Progressive and long-term spectral changesare associated with surface snow redistribution by wind and with a January 2016 regional melt event.
