The evidential base of this application includes geology and geophysics evidence from nine Russian scientific expeditions. They were launched by Ministry of natural resources and environmental protection in cooperation with the Ministry of Defence and Russian Academy of Sciences. It is important to note that the expeditions were performed by scientific icebreakers and submarines. Moreover a geological office has conducted acquisitions of bathymetric multibeam sounder, integrated seismic exploration, airborne geophysical measurements and geological sampling of the main Amerasian and Eurasian basins' structures. During the work researchers used a unique technology, specially designed for difficult ice conditions. The icebreaking research vessel "Akademik Fedorov" was refitted specifically for seismic operations in ice thickness up to three meters.
