We develop a system for three-dimensional (3D) geomorphometric modeling of the Arctic Ocean floor. Previously, a test, low-resolution desktop version of the system was created. Here we present results of the next stage of the project. In this stage, we develop multiscale, desktop and web versions of the system. As an input data, we utilize the International Bathymetric Chart of the Arctic Ocean (IBCAO) 3.0, which represents a 500-m gridded digital elevation model (DEM) of the Arctic Ocean floor and adjacent land territories. To process, visualize, and operate the data, the following software are used: (1) Blender 2.79b, an open-source 3D modeling, rendering, and animation engine software. (2) BlenderGIS addon designed for import and processing of basic geospatial data. (3) LandLord software for geomorphometric calculations. (4) Verge3D, a powerful and intuitive toolkit, which allows Blender users creating immersive web-based experiences. The main steps of the processing are: (a) Geomorphometric calculations. (b) Importing the IBCAO DEM and morphometric models into Blender. (c) 3D modeling. (d) Exporting the 3D models into the web. A final version of the system will provide: (1) Storage of the DEM of the Arctic Ocean floor. (2) Storage of models for 18 morphometric variables derived from the DEM. (3) Interactive, real-time 3D visualization of the morphometric models. (4) Free access to this information via Internet. The system will be used to support marine geomorphological and geological studies of the Arctic Region. The study is supported by the Russian Foundation for Basic Research, grants ## 18-07-00223 and 18-07-00354.
