We develop an information computing system for geomorphometric modelling of the topography of the Arctic Ocean floor. The system development includes the following main stages: (1) Adaptation of previously developed computational methods of geomorphometry and algorithms of interactive three-dimensional (3D) visualization to handle and process big digital elevation models (DEMs); (2) Development of software implementing these methods and algorithms; (3) Selection of the most accurate, free, publicly available DEM describing the topography of the Arctic Ocean floor; (4) Filtering (noise and artefact reduction) of the selected DEM; (5) Derivation of models of morphometric variables from the filtered DEM for several scales; (6) Creation of interactive multiscale 3D morphometric models; (7) Development of a geoportal. The system will provide: (a) Storage of a big DEM of the ocean floor; (b) Derivation of models of morphometric variables from this DEM; (c) Interactive multiscale 3D visualization of the obtained models; and (d) Free access to this information via Internet. The system is created to support hydrographic, marine geomorphological, geological, geophysical, and oceanological studies of the Arctic Region. The study is supported by the Russian Foundation for Basic Research, grant # 18-07-00223.
