Seismic facies investigation and late Quaternary glacial history of the Chilean shelf and fjords and Antarctic Peninsula fjords
High-resolution seismic data collected in inland waters Chile and the Antarctic Peninsula (41$\sp\circ$S-65$\sp\circ$S) were interpreted using seismic facies analysis. Piston cores provide some lithologic control on the interpretation of the seismic data. These data span a latitudinal transect that...
