Fig. 2

Morpho-bathymetric map of the area covered by the multibeam data collected in the BOOST Project along the Pacific side of northern Victoria Land. The BOOST morpho-bathymetric data are superposed onto the digital bathymetric and topographic model of IBSCO24 to fill the areas not covered by the BOOST data. The black segments indicate the five BOOST multichannel seismic lines, while the seismic profile BGR80-100 shows a non-linear trend (processed seismic data of Cruise BGR80 1980 is available at: https://resource.bgr.de/describe/?url=https%3 A//resource.bgr.de%2FMetadata%2FDataset%2F68d180de-f9c6-242f-e8d8-716bba000a36&graph=https%3 A//resource.bgr.de/Metadata/&distinct=0).

The dotted white segments show the traces of the eight bathymetric profiles reported in the top left of the figure, which cross the main morpho-bathymetric features of the area. The yellow segment is the marine magnetic profile (AB) acquired along the southern part of the line BOOST 3. Abbreviations: CH, major channel of the study area; NGT, north glacial trough; MGPL, mega-scale parallel lineations; PMH, prominent morpho-bathymetric high; SGT, southern glacial trough; TMF, trough mouth fan. The morpho-bathymetric map of Fig. 2 was created with the software Global Mapper, version 18.2.2, Blue Marble Geographics (www.globalmapper.it).
