Marine boundary specialists need precise location of key features on the sea bed and marine geological information for the preparation and evaluation of national claims for jurisdiction over seabed resources beyond 200 nautical miles, according to the provisions of Arcticle 76 of the Law of the Sea. Aditionally, such geophysical data are needed in several scientific disciplines, and international multidisciplinary cooperation are be established.

The Arctic Basin includes deep-water sea bed with surrounding shelf seas and adjacent lands drained towards the abyssal core. It is unique in the presence of a variety of structural elements and assemblages forming here a complex mosaic of tectonic features ranging from ancient crystalline shields to spreading modern ocean floor. It is also one of the World's major reserves of mineral resources, including hydrocarbons, coals and precious hard minerals.

Geological and geophysical exploration in the Arctic Basin has been under way for many decades. A wealth of earth science data of both fundamental and applied value has been accumulated by geological surveys, academic institutions, polar research organizations and commercial industrial groups.
An international proposal for cooperation for compilation of a geological-geophysical atlas summarizing available data would help to expand understanding of global geological evolution and adequatly assess to mineral resource potential of the Arctic regions.

The lack of accurate bathymetry in the Arctic is no less a disadvantage for shorebound investigators who require reliable, detailed information. Oceanographers need to know more about underwater relief to improve their models of Arctic Ocean circulation. These studies advance our understanding of the global weather machine and help predict the transport of contaminents.

Detailed bathymetry is essential for environmentalists, who study the sometimes destructive interactions between man and the sea floor, e.g. the dispersion of toxic wastes, or the impact of moving ice on seabed installations.

Geoscientists need detailed information for wide range of investigations from the present distribution of bottom sediments, to the tectonic history of oceanic regions.

Such project aim products among others such as: Bathymetry Map, Orographic Map, Map of Magnetic Anomalies, Map of Gravity Anomalies, Map of Thicknes of the Earth Crust, Map of Total Sediments Thickness, Geological Map, Map of Quaternary Deposits, Tectonic Map, Geomorphological Map, Map of Recent Tectonic Movements, Map of Oil & Gas Potential, Map of Hard Minerals Occurrences, Metallogenic Map and Transarctic Crustal Profiles.
