The Arctic Ocean is one of the least known regions of the world's oceans. Major questions still remain concerning its origins and the processes the led to its evolution; the principal reason is the paucity of seismic data available. While some of this can be attributed to the harshness of the environment on men and machines, it is the ice cover that is the principal limiting factor. It is not stable or contiguous enough to support the use of land techniques, yet only the sturdiest ice breakers can maneuver within it, thereby preventing the use of routine marine procedures. As a result, seismic exploration in the Arctic has been a peculiar mix of land and marine techniques.
