Estimation of Sea Ice Drift Velocity
The Arctic is an important region containing large amount of unused potential. It is expected that a large amount of the worlds undiscovered oil and gas resources are located here, and the shortest route between northern Europe and eastern Asia called the Northern Sea Route (NSR) goes through the ar...

The Arctic is an important region containing large amount of unused potential. It is expected that a large amount of the worlds undiscovered oil and gas resources are located here, and the shortest route between northern Europe and eastern Asia called the Northern Sea Route (NSR) goes through the area.
