A spectacular video showing killer whales in the North Sea has gone online.
The footage was shot from an emergency response and rescue vessel (ERRV) stationed 100 nautical miles north-east of Lerwick.
It comes after the vessel’s chief officer, Graeme Hately, posted pictures of the Orcas on the “Life at Sea on an ERRV” Facebook page.
Under his YouTube username Bigwavemaster1, Mr Hately has recorded other spectacular events such a huge wave hitting the ship. The youtube page has racked up millions of hits online.
Mr Hately, who lives in Nottinghamshire, records a video blog for the crew and is always on the look out for unusual happenings.
