Sea floor bathymetry under Ekström Ice Shelf, Antarctica, from a compilation of seismic vibroseis data
A gridded bathymetry of the sea floor under Ekström Ice Shelf, Antarctica. The seismic data used to map the bathymetry were collected between 2010 and 2018, using two different seismic vibroseis sources. The same snow streamer was used for all data acquisition - a 1500 m long, 60 channel snow stream...
