Seafloor and Ocean Crust Structure of the Kerguelen Plateau from Marine Geophysical and Satellite Altimetry Datasets

The volcanic Kerguelen Islands are formed on one of the world’s largest submarine plateaus. Located in remote segment southern Indian Ocean close to Antarctica, Plateau is notable for a complex tectonic origin and geologic formation related Cretaceous history continents. This reflected varying age oceanic crust adjacent plateau highly heterogeneous bathymetry Plateau, with seafloor structure differing northern segments. Remote sensing data derived from marine gravity satellite radar altimetry surveys serve as an important source information mapping features. study incorporates geospatial NOAA, EMAG2, WDMAM, ETOPO1, EGM96 datasets refine extent distribution extracted cartographic joint analysis topography, magnetic anomalies, grids based integrated performed using Generic Mapping Tools (GMT) programming suite. submerged features (Broken Ridge, Crozet Islands, fabric, orientation, frequency anomalies) enables their correspondence free-air geodynamic setting, seabed southwest Ocean. results show that integrating advanced scripting language improves identification visualization objects. include 11 new maps region covering contributes increasing knowledge French Southern Antarctic Lands.
