oa The use of geoinformation technologies for visualization the features of the underwater terrain of the Antarctic Territories and the geological processes which contributed to its formation

The aim of the presented work is creating a 3D image of the seafloor of the northwest coast of the Antarctic Peninsula in the area of Argentine Islands at the location of the Ukrainian Antarctic station “Academician Vernadsky”. The bathymetric maps of the seafloor of this water area became the actual material. Depths of 730 points in the area of 5,6 km 2 were taken to create the database. ArcGIS methods of spatial analysis were used to create the 3D model: Arc Map 10.1.4, Arc Scene 10.1.4, and Surfer 10. The simulation results are compared by different methods. It was concluded that there is an undeniable advantage of the model built by Arc GIS methods, which give an idea of the smallest elements of underwater terrain. The main geological processes that have formed the modern morphology of the seafloor are the tectonics of fault character and the exogenous erosion glacial plowing processes, processes of the suspension flows that created the submarine valleys between the islands and canyons on the continental slope.
