JNCC/CEFAS April Survey in the North Sea

The time has come again for our JNCC survey staff to join Cefas staff on their research vessel, the Cefas Endeavour, for a 2-week-long survey to Farnes East and North-east of Farnes Deep Marine Conservation Zones (MCZs), within offshore English waters. Monitoring MPAs in general, help us understand how these sites contribute to network of marine protected areas (MPAs) around the UK coastline. Farnes East MCZ has been selected due to the need for a bigger dataset to allow management to be well informed regarding the status of the site. North-east of Farnes Deep MCZ has been chosen due to the need to assess the effects of proposed management measures.

Figure 1: Locations of the sites to be surveyed this April.

Farnes East MCZ contains a glacial trench forming the deepest part of the MCZ. The site is designated for a large variety of sediment types, seapen and burrowing megafauna, and the presence of Ocean quahog. The main focus of this survey is to investigate the glacial trench and the subtidal mud feature within it.
The bivalve mollusc, ocean quahog (Arctica islandica) is a protected feature of conservation importance is found at this site. Additionally, sea pens and burrowing species such as the Norway lobster (Nephrops norvegicus) make their home within the muddy habitats of this MPA.
Our team will be using a combination of mini-Hamon grab and drop-frame camera equipment to better understand the subtidal mud feature within the site. They also aim to identify the quality and quantity of the Habitat Feature of Community Importance (FOCI), sea-pen and burrowing megafauna communities.

North East of Farnes Deep MCZ (NEFD) is mainly composed of sandy sediment, with smaller patches of gravelly sand and mud, which are all protected substrates. These substrates are known to support a diverse range of marine flora and fauna such as anemones, worms, molluscs, echinoderms and fish species.

Wyville-Thomson Ridge SAC: Blog #2

Blowing away those end of survey blues

After beating a retreat from another storm that was blowing across the exposed North Atlantic, we busied ourselves with working at some more sheltered contingency stations East of the Shetland Islands. It seems that you can’t hide forever though, and as the winds picked up, we sought more shelter inshore and sat out a bumpy (and for many of us, sleepless) night.

The following morning, while the southerly gales had died down, the residual swell meant slow progress as we steamed south.

It was fair to say that at this point, team morale was at a low ebb. The rough seas, the unsettled stomachs and the long shifts had taken their toll. But as a group of us were on the bridge after lunch looking at a group of pelagic mackerel trawlers, a cry rang out which lifted everyone’s spirits……"ORCA!"

A bull killer whale came across our bow while a much larger group crossed our wake. They were leaping clear of the water, as they made a beeline for the trawlers, probably excited at the thought of a nice meal awaiting them as the trawlers hauled their nets packed with fish.

It’s amazing how just a fleeting glimpse of some amazing cetaceans can really lift the spirits of the team. For many, it had been their first Orca sighting ever, and for others, their first in UK waters. We carried on the steam to our next survey location with a little spring in our steps, as we got on with our work.

Wyville-Thomson Ridge SAC: Blog #1

Bedrock 'n' Roll

On October 29th, Laura, Neil and I made the long journey from Peterborough to Shetland to join the MRV Scotia and crew, ready to get involved in leg two of the offshore seabed survey. It was pretty darn chilly in Lerwick, but we were raring to go and conditions looked good (as did we!).

We set sail from Shetland at 10am on Monday, October 30th and made our way out to the Wyville Thomson Ridge Special Area of Conservation. This protected area sits about 150 kilometres off Cape Wrath in Scotland, has an area slightly larger than Shetland itself, and is home to some pretty cool marine life. The ridge is a rocky plateau in the middle of the ocean which has areas of bedrock, boulders, cobbles and gravel, made by huge glaciers ploughing into the seabed at the end of the last ice age. It might not sound like a very glamourous place to live, but the rock, boulders and cobbles provide the perfect surface for many seabed creatures to cling on to.

We arrived at the site at about 4:30am on Tuesday, October 31st and plunged our camera system into the depths of the Atlantic Ocean to see what we could find. Laura, Joey and I are part of the night-shift team working midnight to midday, so there’s a lot that goes on in the wee small hours of the morning, in complete darkness… with a coffee (or seven!) in hand. Once our camera arrived on the seabed, expertly controlled by our Marine Scotland colleagues, we eagerly waited to see what the site had in store. 

So far, we’ve seen some brilliant examples of many kinds of colourful deep-sea sponges, sea cucumbers, starfish, anemones, sea urchins and fish. The ‘drop camera’ lets us take video footage of the seabed and still photographs so that we can identify the marine life in more detail. The kit works perfectly as long as the sea isn’t too rough – but the North Atlantic in November isn’t known for its calmness, and some poor weather conditions soon blew in (thankfully we all had our sea legs by that point!).

Having stuck it out for many choppy hours at Wyville Thomson Ridge, we decided to move to a slightly more sheltered site closer to shore so that we could keep working in the poor weather. The site selected was the West Shetland Shelf Nature Conservation MPA. We don’t yet have a good understanding of the sediments and biological communities that live in this protected site, so it was a great opportunity to take a more detailed look using our seabed grabbing gear. We also got a fleeting visit from some inquisitive common dolphin during the night shift, a welcome sight for our bleary eyes!

The Scotia team will be working non-stop, around the clock to make sure we get the most out of this survey trip, whatever the weather throws at us. Collecting information on the biological communities in these unique and exciting offshore sites is really valuable for advice and conservation, as often little is known about what’s living deep beneath the waves (apart, of course, from Sid the stonecrab).

A Day in the Life of a Marine Scientist

I’m Tammy Noble-James, Marine Protected Areas Monitoring Officer at JNCC, and I’ve been aboard the Scotia since we began our survey of North-East Faroe Shetland Channel NCMPA and Wyville Thomson Ridge SAC on 20th October. Having completed leg one of the survey, myself and my shift-mate Jess Taylor (the ‘A team’ as we like to refer to ourselves), have added Offshore Survey Manager Neil Golding to our well-oiled JNCC machine. This is an account of our typical day…

09:30: Having pressed snooze several times I drag myself out of bed and psyche myself up for some exercise. Hitting the ‘gym’ (a shipping container with rowing machine and exercise bike) several times a week is essential to feel vaguely human. It’s easy to become sedentary on the ship, and my colleagues delight in trying to fatten me up with tasty ‘Percy Pig’ sweets on shift, so a burst of activity is a good way to start the day. After the bike session Neil and I suffer through some bootcamp circuits.

Home comforts and survey essentials!
10:30: I hit the shower (no easy feat when the waves are high), and relax in my cabin for a while. We are lucky on this trip; there is enough space for everyone to have their own en-suite cabin. This makes a huge difference when offshore for any length of time; personal space is at a premium when we spend all our work, eating and leisure time together! My cabin is cosy and I never get tired of watching the waves crashing against the porthole.

11:30: Lunchtime. The job of the offshore chef is fraught with danger… get it wrong and you could have a mutiny on your hands, or at least a seriously grumpy crew. Luckily, we have a fantastic galley crew who work tirelessly to keep us well-fed and happy with a menu of delightful grub.

12:00: The day shift begins, with a turbo cup of coffee and a handover with the night crew. They have completed 10 drop camera stations whilst we were asleep, adding significantly to our knowledge of the stony reef habitat within the Wyville Thomson Ridge SAC, and slowly building the first datapoint in our monitoring time series for the site.

12:30: Our first camera transect of the day. The three of us JNCC scientists and a Marine Scotland Science electronic engineer are in the camera operations centre (another shipping container), all working to collect georeferenced images of the seabed. Our engineer deploys the drop frame camera through the murky depths, passing the odd jellyfish, until we reach the rocky seabed at 450 metres. We take photographs and positional data as the camera glides above the seabed, spotting sponges, redfish, sea cucumbers, sea stars, sea urchins and squat lobsters. This rocky material, deposited thousands of years ago by icebergs ploughing through the seabed, provides a complex habitat and attachment surface for a wide range of deep-sea creatures.

The 'A Team' in the camera operations centre.
15:00: Time for more coffee. We have around 30 minutes to travel between each camera transect, during which we refresh our caffeine levels whilst keeping on top of our data management. When we’ve completed our data entry, Dave the deck technician drops in to teach us some nautical knot-tying skills.

17:30: We change out of our protective gear and head up to the mess for a delicious curry. There are a few faces missing at the table… some newly arrived scientists are suffering a bout of sea sickness and are tentatively nibbling on crackers in their cabins. This debilitating condition is unfortunately all too common up here in the Atlantic due to the stormy November weather. Just another sacrifice in the name of science!

00:00: We made it! After 12 hours of toil we are delighted to find we’ve completed 11 transects (one more than the night shift!). Our colleagues arrive to relieve us, and we are free to enjoy twelve hours of unfettered freedom and sleep before we come back and do it all over again.

North East Faroe-Shetland Channel NCMPA: Blog #4

We’re halfway there…

Hello once more from the Scotia, where the first leg of our JNCC and Marine Scotland Science Marine Protected Area monitoring survey has drawn to a close. We have begun making our way from North-east Faroe Shetland Channel NCMPA to Lerwick, Shetland for a day in port to facilitate a staff change before we make for our second survey site (Wyville Thomson Ridge SCI), which is situated to the north-west of Scotland. 

We have collected a lot of very useful information about this site in what has been a great week and a half out here on the north-eastern edge of the UK’s waters.

We have collected data from four survey areas (Boxes A, B, C, and D). The black crosses in the image below show the 37 locations where we completed drop-frame camera stations in Boxes A, B and C. We also completed 15 camera chariot transects in these boxes and collected 8 seabed samples from Box D. 

Thanks to the persistent hard work of the crew and JNCC and Marine Scotland Science scientists aboard, and some good luck with weather, we have achieved our objectives and now have a comprehensive dataset describing the deep-sea sponges and other animals we have observed (some of which have been mentioned and shown in previous blogs), and the seabed habitats which support them. This dataset can now be used to help monitor change within this MPA into the future. 

We will continue to blog throughout the second leg of this survey, so please do stay tuned for new updates and images from the good people on the good ship Scotia!

North East Faroe-Shetland Channel NCMPA: 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.

North East Faroe-Shetland Channel: Blog #2

We have been busy here at North-east Faroe Shetland Channel since the last blog post. We have all managed to get our sea legs now and have managed to complete all of the chariot video tows. This type of video tow is useful as the equipment can be towed much quicker and for longer than the drop frame camera system (more on that later), allowing us to view a much larger area of seabed. During these tows we have seen a large variety of deep-sea sponges and many different deep-sea fish.

To make the most of the time we have at sea, the team has been split into two, allowing sampling to happen 24 hours a day. Half the team works the “day” shift, midday to midnight, and the other half work “night” shifts midnight to midday. 

We have also been making headway with the grab sampling. This consists of sending the equivalent of a large spade down to the 500m depth and scooping up a small amount of the seabed which we then subsample to investigate sediment particle size. The remainder of the sample is sieved through two different sized sieves to see what marine life and seabed material we have picked up in this area. 

Listening to a variety of musical tunes, going through the decades from 70’s to 80’s, through the shifts has helped the work move along, with the addition of tasty meals and plenty of chocolate and biscuit snacks. We are now moving onto the drop-camera survey. This camera allows us to take high quality still images, which will later be used to identify the different animals seen in the chariot videos.

Sadly, Storm Brian managed to find us yesterday evening, raising the waves to stomach churning levels. Work was suspended as the winds picked up to levels which did not allow us to continue grabbing or video work. This gave the team plenty of time to make sure all the information we had collected was backed up to the various hard drives and computers. It also allowed some time for making sure all of the data is in the correct format, writing blog posts and fixing any computer glitches.
