AS PART of the 11th International Deep-Sea Biology Symposium held in July at the National Oceanography Centre in Southampton, maritime researchers and professionals were invited to submit photographs and video clips to the first BP Kongsberg Maritime international deep-sea image competition.

An image of a shark taken by researchers at Oceanlab – the University of Aberdeen’s deep-sea research facility – was selected for the Highly Commended Award in the Underwater Images, +200m category.

Nicola King, a PhD student at Oceanlab, said: “The image is of a shark, Deania calcea, of which the common name is the Birdbeak dogfish, with cutthroat eels, Synaphobranchus kaupii, in the background.

“The image was taken off the west coast of Ireland in April 2004 at 931m depth. The camera is positioned on a lander – an automous free-fall system, looking out onto a baited arm.”

King explained that the scavenging animals are attracted by the smell of the mackerel they use for the bait. She said: “We can now use the information from the images to assess abundance – how many scavenging animals there are, the number of scavenging species within the region, and their size.

“These images are significant as they photograph animals which are being affected by overfishing in this region.”

The images were judged on their visual impact, their importance to science, the novelty, the rarity of the subject, but most of all the way they capture the essence of the deep ocean and how we explore it today.
