There is a possibility that the incursion was instigated as part of a temporal loop; In a later Borg incursion in 2373 the Borg launched a Borg sphere which travelled back in time to attempt to prevent Earth's first contact with the Vulcans in 2063. Fortunately the USS Enterprise-E followed the sphere back in time and stopped the Borg. While the Enterprise did destroy the sphere, some debris did crash-land in the Arctic Circle, where it remained beneath the ice for the next century. In 2153 the debris were discovered and investigated by the Arctic Archaeology Team. The team discovered two frozen Borg drones, which after being removed from the ice were able to regenerate and subsequently assimilated the team and their ship. The starship Enterprise was ordered to intercept the vessel, and recover the team if possible. After two confrontations, it was clear that the team was beyond recovery and the ship was destroyed. Dr. Phlox, who was nearly assimilated, reported that he felt a group consciousness which attempted to transmit a series of numbers. Later analysis of the numbers by T'Pol revealed that they gave Earth's coordinates, and were sent to the Delta Quadrant, though would not be of an immediate concern as the message would take two-hundred years to reach its destination.
