Central and eastern Bransfield basins (Antarctica) from high-resolution swath-bathymetry data
For the first time complete swath bathymetric maps of central and eastern Bransfield basins are presented at a medium scale and detailed morphological descriptions are provided. Bathymetry reveals morphological structures which provide important information about the structure, volcanism, and kinema...
