I
see auks surprisingly little from survey vessels and oil platforms in
the North Sea. Sometimes they seem very tame and feed right next to the
vessel - possibly attracted by the aerated water caused by DP vessels.
Auks have been seen diving to incredible depths by ROVs (Remotely
Operated Vehicles) operating on oilfields and pipelines in the North
Sea - with such birds captured on video as they "fly" past the vehicle.
