The A-6 excavation team, also known as the Arctic Archaeology Team 3, was a Human arctic archaeology group from the Earth Sciences Institute that studied the debris from a Borg sphere found in the Arctic Circle in 2153.
During their excavation, they found two Borg drones frozen in the ice of a glacier and still intact. Not knowing what they had found, the team allowed the Borgs' regeneration process to resuscitate the drones, and were later assimilated. The drones and assimilated team subsequently left Earth's system in their spacecraft Arctic One, which was also assimilated.
The team was supposed to check in with the Science Council, and when they didn't after three days, Starfleet was notified and investigated. (ENT: "Regeneration")
The assignment patch for the A-6 excavation team (which was auctioned of in the It's A Wrap! sale and auction on eBay [1](X) ) read only "Arctic Archaeology Team 3" and the names Moinger [sic], Rooney, and Drake. The same logo was also seen on several equipment pieces of the team.
