A university researcher has said it was a "huge honour" after he helped create the latest Sir David Attenborough documentary.
Dr Bryce Stewart, an associate professor at the University of Plymouth, worked with broadcasters on the film Ocean.
Dr Stewart's guidance was required when the crew showcased a carefully controlled study as part of the film to better understand the effects of dredging – a method of fishing which sees boats tow a heavy metal frame with a bag or net – on marine life.
He said: "It was a huge honour to work on the film Ocean with David Attenborough, and I had the privilege of helping film some of the scenes and advising on the script."
