The authors are grateful to the Ministry of Natural Resources and Environment of the Russian Federation and to the Federal Subsoil Resources Management Agency for the opportunity to publish this paper. We are especially grateful to the professional and dedicated crews of all vessels, submarines, airplanes and helicopters and to all the specialized researchers from different countries taking part in these Arctic Expeditions. Many friends and colleagues, such as the late R. Scott, are in our memory for their pioneering contributions. Processing of all data of many kinds was conducted in different companies in Russia as well as other countries. We express many thanks to Tim Horscroft and Gillian Foulger for the invitation to write this paper. Gillian Foulger proposed the title and general structure of this paper. The work of AMN, SIF, KFS, EAR and NNZ was supported by RFBR grants ( 18-05-70011 and 18-05-00495 ). The work of SGS was supported by RFBR (Russian Foundation for Basic Research, Russia) grant 18-05-70061 . We thank the anonymous reviewers for generous, detailed, and constructive criticism and editing of out text.

N2 - Over a period of the past 15–20 years, the Russian Government implemented the Arctic Mega Project for geological and comprehensive study of the Arctic Ocean. In this paper we discuss the methods that were used in the implementation of this project. In the course of several expeditions, multiple types of data were acquired, which included: (1) seismic data of different types, (2) subbottom profiler data, (3) geological sampling on slopes of the Mendeleev Rise with the use of special equipment, (4) borehole drilling, (5) gravity and magnetic anomalies, (6) offshore geodetic data, (7) multi-beam bathymetry surveys, and (8) field surveys on multiple Arctic islands. Several nuclear icebreakers and a scientific research submarine were deployed in these operations. Specifically, more than 23,000 km of 2D multi-channel seismic lines and more than 4000 km of wide-angle refraction/reflection seismic lines were acquired, in addition to subbottom profiles for the Eurasia Basin and new bathymetric data of the Arctic Ocean. The new database is intended to facilitate the development of new insights into Arctic geology and geodynamics and contribute to a better understanding of the structure and tectonic evolution of the Arctic Ocean as a whole.
