The authors describe creating a corporate template for a spatial database that allows collecting all materials obtained during sea engineering complex geological and geophysical surveys conducted by the JSC Marine Arctic Geological Expedition into a systematized structure. Organization, features and functionality of the database are considered due to the data collected in 2022 as a result of field work aimed at justifying the feasibility of using a site on the Kara Sea shelf for the place of a semi-submersible drilling rig. The developed database is unique for the region, but at the same time universal for the specifics of the research. It does not only provide for the storage of information on a wide variety of work types (including high-resolution seismic exploration, low- and high-frequency continuous seismoacoustic profiling, side-scan sonar, differential magnetometry, multibeam bathymetric survey, sampling and electrical exploration using the near-zone field establishment sounding method) but also serves as a convenient tool for preparing a unified catalog of thematic maps
