Near‐surface environmentally forced changes in the Ross Ice Shelf observed with ambient seismic noise
Submitted by susan on Wed, 2018-10-17 15:47
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.
