Abramova 1 1 Geological Institute Russian Academy of Sciences, Russia ABSTRACT Several types of artifacts have been identified in digital bathymetry models which represent shape of the Arctic seafloor. This work presents the classifica- tion of the types of artifacts encountered in several versions of bathymetry grids such as IBCAO, GEBCO grid, SRTM30_Plus and Global Topography. All of the above-listed products are publicly available through the internet. The artifacts observed could mislead geological interpretations; therefore it is necessary to emphasize the limitations of the portrayal of the seabed by digital bathymetry models. Any digital bathymetry model is a compilation of various data sources with different accuracies, resolution and distribution. Artifacts in the bathyme- try grids are characterized by presence and distribution of the source data. They can be caused by systematic errors in the source data, differences in source data horizontal resolution, by the lack of source data, by gridding algorithm and interpolation method (e. g. filling data gaps with gravity, spline interpolation). The encountered artifacts were classified according to the sounding source data types which characterize them. These include: multibeam surveys, singlebeam surveys, single spot sounding, depth contours digitized from contour maps, “patching” different data sources, coastline dataset used for gridding, as well as the lack of any data. The observed artificial “morphology” in bathymetry grids include small and large scale artificial features: ridges and troughs, peak-like or pit-like features, flat areas, deeps and rises, artificial steps, terracing on slopes and negative depth values on land. Keywords: artifact, digital bathymetry model, IBCAO, GEBCO, Arctic INTRODUCTION The release of global (e. g. GEBCO [13], SRTM30_Plus [2], Global Topography and regional compilations (e. g. IBCAO [6]) improved our understanding in the most of earth processes, since bathymetry serves as the base map for any geological, geophysical, environmen- tal or oceanographic investigation. Beyond fundamental research bathymetric applications vary from navigation purposes to studies of coastal erosion and environmental issues. The off-shore conti- nental shelf bathymetry is of particular interest to coastal states’ resource sovereignty, exploration for natural resources, submarine cable planning, habitat mapping, fisheries management, predicting landslides and modeling tsunami impact [1]. Nowadays there is a drastic increase in the number of applications of digital bathymetry 1 St. Petersburg, Russia, 17–19 May 2018 Theory and Methods of Polar Science and not only for the scientific purposes. Ever since the release of such exploratory tool as Ocean layer in Google Earth, basically an- yone can explore and interpret marine environments and the shape of the ocean floor. Meanwhile even in the current bathymetric era of high resolution and accuracy multibeam echo sounding and global remote sensing technologies (satellite
