The sun is back!

We left Rockall Bank a couple of days ago and steamed back inshore (past foggy Rockall!) to a new site at the Hebridean Terrace Seamount which is about 50 miles or so west of the Outer Hebrides where we've been conducting a short survey for JNCC. Underwater the site looks pretty cool, with some impressive cliffs sticking up from the seabed and it looks like a completely different set of fish as well. It's not going to be possible to tell whether the differences are caused by depth (the seamount is much deeper than our previous sites, at 1200-1800m compared to 800m) or by the different habitat, but it's very interesting to see.

Unfortunately, the surface is less exciting and we've had barely any sightings of anything since we got here. Even our entourage of fulmars and gulls has left us now, so I've spent much of the weekend wondering what the hell to talk about today. In true British style, it turns out I'm going to rely on that old classic: the weather!

Well not really, but just enough to say that the clouds finally lifted last night and we were treated to the first clear(ish) sunset in almost two weeks which brought out the scientists and their cameras!

A Day in the Life... On a Research Cruise

There’s nothing quite like the combination of fog, rain and a big swell at sea to really limit your options for photography! The weather yesterday and today has been too poor to put the ROV in the water and too foggy to get any decent photographs so we’ve had a quiet couple of days to catch up on some writing and data processing in the labs. But, all work and no play makes scientists at sea go crazy, so I thought today I’d write a little bit about a typical day on a research cruise and what we get up to out here to maintain some semblance of sanity!

Bet you can't spot me!

I’m writing this during my third offshore cruise, and during each one the scientists have been put on (usually 12-hour) shifts so we can keep working around the clock. The RRS James Cook costs about £50,000 per day to hire (including fuel, consumables and crew wages etc.) so it’s important to try and make the most of every hour we can get on board, especially since the chance to participate in a research cruise often represents a one-off opportunity to get your data. Unlike other fields, with deep-sea research it’s not like you can just pop 300 miles back offshore if you forget something or lose a sample! With that in mind, even working for 12 hours or more through a night shift doesn’t seem quite so bad.

So regardless of what time you actually wake up, a typical day will start, as it does anywhere, with breakfast and a coffee in the ship’s galley before checking in with the shift leader to see what the programme of work will be for the day. The shift leaders are responsible for keeping things running through their shift and will liase directly with the expedition’s Principle Scientist and to make sure that everyone gets the samples they need from the trip. They are also the ones who will be at the forefront when plans need to change to allow repairs to be done on a piece of kit or if bad weather comes in and forces us to rethink what we’re going to do for the day.

Nothing like a giant bucket of mud to keep everyone happy!

Since every research cruise is designed with a particular purpose in mind, the type of work being done will depend very much on what the aims are. The cruises I’ve participated in have mostly focused on ecological surveying using ROVs, towed cameras or trawling for example, but we’ve also done plenty of mud sampling, box coring, water collections and acoustic mapping as well. Regardless of what type of cruise it is though, one of the things I really enjoy about working on these ships is the real sense of camaraderie that develops from joining in with the deck work in particular, whether it’s carting buckets of water around for the on-board aquaria or being up to your elbows in abyssal mud at 2am on a pitching ship!

But like I said, you can’t work for 14 hours a day for 4 weeks straight without needing some downtime, and fortunately the cruise ships I’ve been on have been well-supplied in terms of entertainment. The James Cook for example has a video room for watching films in, a small library full of novels, a good-sized social area for watching TV and even a Wii with a few games! For me as well there’s also the photography to keep me busy, whether it’s shooting the wildlife or shooting photos of the work that we’re all doing.

Wii tournaments can get pretty intense

So that’s more or less it really for a typical day at sea! The weather has just kept on getting worse and the captain’s ordered the decks secured now while we head to our next station through a 3-4m swell (about 10-12 feet I think), but the birds seem to be thoroughly enjoying themselves so I’m off to try and get some shots of the stormy seas!

Thanks to Karl Attard and Millie Sharkey for providing today's photos :)

Rain? Time to get the macro lens out!

Well, it’s a rainy grey day out here in the middle of the sea, which actually makes a really nice change from the sunshine (yes I’m Scottish, yes I miss rain!), but as much as I enjoy shooting in the rain, with everyone hiding inside on their laptops and the wildlife pretty subdued it seemed a good time to get out the macro lens and try some specimen shots.

 Even the fulmars looked fed up with the weather

In order to get decent quality images of the animals we’re collecting with the ROV and the boxcores, I brought along a little 10L aquarium tank, a big strip of black cotton to surround it with and a couple of sheets of 2mm plexiglass to act as a sort of clear shelf inside the tank to support the animals (thanks to Millie Sharkey at Bristol Uni for her advice on the setup!). We set it up tonight in one of the outdoor labs and immediately entered into a bitter battle against the constant condensation forming on the glass... Once the cold room empties out a bit I’ll need to try and grab a space in there, but I’ll need to wait for the science to get done first.

I’ve only got one flashgun with me, so unless I can find some other sort of torch or waterproof lamp, I’ll be going for the side-lit look!  Anyway, here’s a few first attempts:

So it’s an all right start I think! Some of these have had a bit of work done to them in Photoshop to remove reflections from the glass and particles from the water, but otherwise they’ve only had the usual contrast and sharpening. If anyone has any handy tips for improving the lighting on these though I'd be really grateful! Chances are we're only going to have the one light source, but we can probably build more or less anything we need.

Wind, waves and wildlife!

Well, the good weather finally left us and we’ve had a grey and windy day today which has come as a bit of a shock to the system after all the sunshine we’ve been treated to the last week! Still, it’s great news for photographing seabirds though, as they seem to prefer a bit of wind for flying in to help them glide over the waves, or sit in the up draughts alongside our six-storey  ship. I must admit, it’s been great to be outside on the back deck shooting seabirds in flight again! I think the last time I was really able to stop and shoot seabirds was probably back in 2010 when I was working on the fishing boats. I’ve had a few trips in the meantime obviously, but I’ve been mostly shooting coastal birds for a while now and it’s brilliant to be back out with the gannets again.

The mystery of why there are so many birds around has been solved as well and it turns out that they’re all here making the most of the food waste that gets dumped from the kitchens. All our other waste is either recycled or incinerated on board to minimise the environmental impact of the ship while it’s working, so it’s only biodegradable waste that is put over the side. Still, it’s good enough for the fulmars and gulls, though it’s a little strange watching them fight over bits of watermelon

The fulmars are here in one of the largest groups I’ve ever seen around a ship and there are probably at least 100 of them following us around. I love how at home seabirds are in the oceans regardless of what the sea state is like and it’s great watching them shrug off breaking waves and strong winds like it’s nothing at all.

For a little while we were also joined by a few gannets which circled the ship for about an hour or so, gliding around the ship and floating in the air by the bows.

More entertainingly, for some reason every time the gannets landed on the sea they would target a fulmar and force them to rush out of the way. I’ve no idea why they were doing this since nothing was feeding at this point, but I don’t know an awful lot about birds so if anyone else has any suggestions I’d love to hear them!

The gannets liked to use the fulmars as landing pads for some reason

Deep-Sea Science at the Outer Hebrides

So, after spending two years of my life working on the Isle of Lewis looking at fisheries bycatch I’m back in the Hebrides again doing deep-sea research. This time around we’re here for one week of a four week cruise investigating the effects of global climate change and ocean acidification on the cold-water coral Lophelia pertusa (yes, Scotland has its very own coral reefs!). Or at least, that’s what everyone else is studying – my interest in this cruise is to collect video transect data from the Remotely Operated Vehicle (ROV) and use that to look at how fish use the reefs and surrounding areas as habitat.

So far things have been going pretty well, and it's been crazy busy with collecting samples, hosting a BBC film crew and school group from Benecula and dealing with the constant stream of video files coming out of the ROV! We had a few teething problems with the ROV during the first couple of days of the cruise, but they seem to have been more or less sorted out and we’ve been able to conduct some good long dives for sample collection and filming plenty of video footage for me to go through when we’re all back on land! I can’t put up any of the underwater images as yet since they belong to the cruise, but we should be putting a few up on the official cruise blog some time soon. In the meantime, I can share some of the surface shots of the gear we’re using.

This is our ROV and the most important (and expensive) piece of gear we have. With this we're able to collect precise samples, film everything we see underwater and even conduct experiments on the seabed.

Recovering the box corer. This piece of kit goes down on a winch cable and activates when it hits the bottom forcing the scoops closed and (hopefully) bringing us back up a big box of mud!

We did some maintenance work today as well for one of the long-term monitoring stations out here. This is the team preparing to put everything back.

As far as the wildlife goes, it’s been fairly quiet around the ship so far with relatively few sightings (which is a bit surprising considering that the perfectly calm weather we’ve been having is ideal for whale and dolphin spotting). Still, we have seen a few common dolphins and were visited by a basking shark a couple of evenings ago which was very cool!

I’ve been experimenting with taking some video footage with the 7D too, and I’ve got a few nice clips which I’ll get up online when I get home. Sadly the internet connection out here is far too limited to allow any kind of video upload, but to be honest we’re pretty lucky to get anything at all so I’m not complaining. We’ve also got a new mascot on board which doesn’t seem to want to leave the ship and has been here for about 3 days...

Anyone recognise this pigeon? It's still on board...

Anyway, we’re heading offshore now so the next update will be from the middle of the Rockall Trough (that’s about 200 miles west of Scotland).

The last land we'll see for 3 weeks. Could definitely be worse!
