North East Faroe-Shetland Channel: Blog #3

Sid the stonecrab left the house early today to get a head start on his early morning seabed scavenge. At these depths there is no natural light, the water is clear and nearly as cold as that at the poles. The seabed here is not barren, however... far from it. Sid passes through areas thick with a variety of deep sea sponges growing in fantastic forms and sizes as he forages. The area supports a variety of other animals too like cushion stars, brittle stars, pencil urchins, anemones, squat lobsters and fish like ling, torsk and deep sea red fish.



Suddenly, a brightness he has never seen before descends from above, stopping just metres away from him. The brightly lit metallic object pauses for only a moment before moving on, bobbing along its way in the deep. Little does Sid know that hundreds of meters above him, the Marine Research Vessel Scotia is carrying out an extensive survey of the sponge grounds that are his home. In a joint operation, JNCC and Marine Scotland Science (MSS) have been surveying the North-east Faroe-Shetland Channel Nature Conservation Marine Protected Area (NEF NCMPA) for the last week as part of the UK’s MPA monitoring. 


Now that the storm on the surface has abated, the sea is again calm enough to resume survey operations. The joint survey team have been collecting video and photographs of the seabed for the last 36 hours using a dropframe camera system. The sophisticated camera systems are repeatedly lowered off the back of the ‘Scotia’ into the deep in search of their quarry: the deep-sea sponges and their associated animals, including Sid (much to his surprise!). The intrepid crew, a mixture of professional seamen and scientists, will keep up this work twenty-four hours a day until they have collected enough footage to form a picture of this little-known area of seabed. This work will help to better understand and protect Sid’s home among the amazing deep-sea sponges of the Northern North Sea.
