Criteria for the Outer Limit of the Continental Shelf of the Coastal States According to the Requirements of the UN Convention on the Law of the Sea. G. D. Naryshkin, D. M. Petrov, A A. Yermolayev, S. P. Alekseyev, A. V. Kostenich – Navigation and Hydrography. – 2013. – No. 36. – Ð. 61–68.
By the results of hydrographic surveys the bottom relief of the Arctic basin is one of the best studied areas of the world ocean whose different-scale forms of relief are represented by different-scale bathymetric charts and morphological maps. Analysis of the bathymetric data base enabled to determine the specific features of the bottom relief and regional regime of the basin sedimentation which resulted in arbitrary geological interpretation of the submarine features that is at variance with the well-known classification of the bottom relief and different hydrodynamic models. Especially these contradictions became apparent when implementing the requirements of the International Convention on the Law of the Sea (1982) for substantiation of the outer limit of continental shelf of the coastal states in the Arctic basin. To provide the agreement between the obtained notions of the basin bottom relief and the accepted notions and terms of geomorphology, it is necessary to consider in detail the criteria of the outer limit of the continental shelf that are defined by the requirements of the Convention, including the direction of explorations on this problem.
Key words: the Arctic Ocean, bottom relief, sea borders, the Arctic basin, UN Convention on the Law of the Sea (UNCLOS).

The Technique of Refining the Geopotential Field Over the Oceans. I. A. Gotyur, A. V. Kostromitinov – Navigation and Hydrography. – 2013. – No. 36. – Ð. 97–102.
The following technique based on spline approximation is offered. It allows to use the information about the field with the refinement of geopotential field over the oceans. The weather satellite data are the source of cloud field information. To construct the approximation spline that allows to obtain the refined values of the geopotential, the zonal and meridional components of the wind velocity vector are used as the values of directional derivatives. The zonal and meridional components are determined using the satellite data.
Key words: refinement of geopotential field, use of weather satellite data, correlative extreme method, spline approximation.
