Last night we got A LOT of rain. Bizarrely, it made all the frogs come out and they were so loud they kept us up most of the night!

 

 

We woke up bright and early (this is becoming the norm now!) and the sun was there to greet us. But alas, so was the wind. We set up a mock Attenborough Studio right on the beach – complete with chairs, coffee table and an audience! And after a few technical glitches, we video-linked live to London and spoke to Nature Live host Natalie and Professor Geoff Boxshall. Great fun and Geoff even put in a request for some specimens so we’ll be heading to the other side of the island later in the week to collect some copepods for him.

Diva and I also live-chatted with some schools online – Bowhunt, Wigmore, Elmshurst and Ashcroft – who asked some great questions! We’re looking forward to the next session on Tuesday.

 

Helena and Diva showed how diligent they were; while the sun was shining they were hunched over their microscopes looking for new species. Extra credit for them!

 

 

 

 

After lunch we all headed out to the sea grass beds to see what we could find.

This is an area of shallow sea grass that becomes visible at low tide and is home to an array of marine life. I was warned to wear shoes as the sea grass beds are teeming with lionfish - very dangerous. Nick, who grew up on the island, told me that they’re an invasive species, originally from the Indo-Pacific. The reason they’re so dangerous to fish in these waters is that some of the fish don’t actually recognise them as predators and there’s nothing around that predates them.

 

P1000172.jpg

Above: Beautiful, but beware of lionfish...

 

During our beach bioblitz we found anemones, sea squirts, conch shells, sea urchins…and 2 lionfish!

The good news is that the weather is improving so we're going on the boat tomorrow! Hopefully we’ll find the whale bones and some Osedax!

We are all waking up really early - around 6am when the sun comes up. After breakfast we loaded up the golf carts with spades, sieves and sampling jars and we were ready to go panning for worms. We ventured out to the mangroves on the other side of the island, where we were relieved to find that the wind was much less intense.

 

helena.jpg

Once we reached the marina we had to get out to the sampling site and what better way than to kayak. Then we had to do some serious digging, put the muddy sand into a bucket and kayak the samples back to the shore. To be fair, Nick did a lot of the hard work!

 

It was then up to Diva and Helena to sieve through all the mud, this may sound easy but when you’re looking for tiny creatures you have to be very precise and it can take quite a while.

 

 

We found a few large creatures, such as sea cucumbers and a giant anemone, but the really exciting stuff is only visible under the microscope. Helena was really excited as she thinks she has found a new species of the marine worm Ophryotrocha under the microscope! Obviously we can't tell for sure until we get back to the Museum but it's great to think that it might be so.

 

 

Above: Could this be a new species of the marine worm Ophryotrocha?

 

One of the other highlights of the day was that Gill got to see Cassiopeia jellyfish for the first time in the wild!

After lunch (which was rice and beans!) we spent a good part of the day testing REX before we send him into the deep later in the week. Adrian and Leigh set up a mission control in a repurposed bathroom on the beach and we sat and watched REX manoeuvre through the shallow sea grass beds.

Here is when REX met a lionfish…

 

 

On Thu 8 Mar (which is tomorrow for me as I write this) we'll be linking live to the Attenborough Studio so do join us if you can!

After a very early start and a shaky flight across the Atlantic we landed in Nassau.

That was the easy bit we found, as we then had to catch various modes of transport until we reached base camp but, luckily, none of them involved 12 hour hikes! After landing in a windy Nassau we had to get a small plane. It was slightly terrifying but the pilot was amazing.

We then met our taxi driver, Fredrick, who as well as driving visitors around the island also grows the best tomatoes and cabbages on Eleuthera, where we are staying. He took us on a detour to his farm and gave us a stock of fresh vegetables. We were very grateful and it was a great example of Bahamian hospitality. On the down side, I got bitten by ants while digging up cabbages on the farm. Fredrick escaped unscathed.

Next, was the Night Rider water taxi that took us a short way across the ocean where we were met by Adrian (who had flown out a couple of days earlier) and our final mode of transportation … golf carts! My golf cart driving lesson is tomorrow and I am VERY excited.

We begin with all the science in the morning. Tonight we're just settling in to our new beach home…

The Museum has recently acquired a great bit of kit that allows us to complete our work in the Bahamas. It’s a remotely-operated vehicle that we lovingly call REX (short for Remotely-operated vehicle for Education and eXploration).

 

rov-REX-in-the-water.jpg

 

It has the ability to go to depths of 200 metres and we’ll be using it to retrieve the experiments that were laid down late last year. It has a robotic arm too and apparently if you can play XBox you can operate it pretty easily!

 

robot arm.jpg

 

The really special thing about REX is that it has a HD camera attached to it so we can film amazing footage of the sea and the life within it. It’s important for scientists to observe how animals behave in their natural environment, especially when it comes to creatures like jellyfish, as when you bring them up to the surface they look like amorphous blobs.

 

Like I’ve said before I’m really looking forward to seeing sharks and going by the video shot last year I won’t be disappointed!

One of the objectives of our field trip to the Bahamas is to see if a species of the bone-eating worm, Osedax, can be found there, which would be a first for science. However, if we're to find Osedax worms in tropical waters we need to lure them to us.

 

We know that these bizarre creatures bore into the bones of dead whales that have fallen to the seafloor. Finding a whale skeleton naturally in the waters in the Caribbean could take weeks or months and although a stay that long sounds like an attractive prospect it wouldn't be the most economical. Instead, the team thought to sink pieces of whale bone and wood to attract the worms.

 

So, in October 2011, Adrian Glover and Nick Higgs went to the Bahamas to do just that. Here is a picture of the experiments...

Weighted baskets with bones and wood attached - the floats will (hopefully!) help to locate them

The baskets were dropped to the sea floor at different depths; one each at 19m, 30m and 55m.

 

Here is the experiment that was lowered at 19m in October - will we be able to find it on our return?

Now, 6 months later, we're going to retrieve them and hopefully in that time an Osedax species will have colonised them and we'll find the first record of the worms in the Caribbean. We’ll keep you posted!

Will we find Osedax in tropical waters?

On Friday and Saturday, I introduced everyone else who is going to the Bahamas, and now there’s only me left:

 

Being a Nature Live host, I have always worked closely with Museum scientists but I’ve never had the opportunity to accompany them on a field trip. I feel extremely lucky to be going to the Bahamas and it will definitely make a change from being in the Attenborough Studio at the Museum (see me hosting a recent session about the Bahamas with Adrian Glover here).

 

The really exciting thing for me about this field work trip is being able to engage our visitors with Museum science as it happens, live, on the other side of the Atlantic. Hopefully it will help people see we are much more than the ‘Dinosaur museum’!

 

Highlight?

A highlight for me would be to see sharks, even if it is through our eyes in the ocean - the remotely operated vehicle, REX. I also hope we find a new species of Osedax so that I can have first dibs on naming it! (I realise I won’t get the honour but a girl can dream!)

 

Anything worrying me?

I am a little worried about the possibility of getting sea sick. I don’t do well on boats – a fact I have kept to myself until now!

 

I hope you’ll follow our trip and check in for the latest on our journey...

What do you do at the Museum?

I'm a Media Technician supporting Nature Live and other learning programmes.

 

What’s the best bit about your job?

I’m lucky, my job is pretty diverse. One minute I’m fixing the interactive exhibitions in the Museum’s galleries and the next I’m doing a Nature Live with video-links to NASA. I’m constantly researching all the coolest gadgets and trying to integrate them into our live events. I get to work with computers, cameras, video editing, special effects and sound.

 

What are you most excited about seeing on the trip?

Amazing HD footage of marine life - techno geek I know! But my favourite thing about this trip specifically is being able to reach out to Museum visitors and helping them engage with the science that goes on here.

 

Is anything worrying you about the trip?

I’m worried about getting sand in the technical equipment. Oh and sun burn.

What do you study at the Museum?

I study string jellyfish, or siphonophores, which are very delicate deep sea species that pass their whole life cycle in the plankton, and are not normally found anywhere near the shore because of turbulence.

 

The only jellyfish that lives on the surface of the water is the Physalia - also known as the Portuguese man of war. Once it has matured it has a massive float which means it cannot sink below the water.

 

What are you most excited about finding/seeing on the trip?

Rarely collected species of siphonophores from the Tongue of the Ocean - several new species were described from the area in the 1980s to 1990s - but have not been found since. I have only ever seen about 2 live siphonophores in my life, as I work on preserved material, so anything will be exciting for me.

 

What do you miss the most when you go on field work?

Probably my husband, who will be at home whilst I’m in the Bahamas. This trip is a first for me because I am a non-funded Scientific Associate in the Museum, and just do my research for fun, not money! This is the first time I’ve ever been offered a place on a Museum expedition, so I am very excited to be going, and grateful for being invited to participate.

Helena-Wiklund.jpg

What do you study at the Museum?

I study polychaetes (marine segmented worms), from the deep sea and from whale-falls and hydrothermal vents. Polychaetes are related to earth worms but usually a lot prettier and more colourful. I am describing new species that we discover in the deep sea samples, and I sequence their DNA to see how they are related to each other.

 

The DNA sequences can also be used to study how these worms move around in the sea. It can be useful to know if they can go anywhere else if their current habitat becomes inhospitable or if they're stuck in one place and doomed when bad things happen.

 

What are you most excited about finding/seeing on the trip?

If we get those whale bones up from the sea floor, I am sure that there are undescribed worm species on them. I am very curious to see what they look like, and also to bring them back to the lab and sequence their DNA to see where they belong among the other worms from similar habitats.

 

Where have you been previously on field work?

In my undergraduate studies I spent one year on Svalbard studying Arctic Biology, and we went on several field trips both on sea and on land. And then I've been to New Zealand, Chile and on an expedition to the Mid-Atlantic Ridge, and on several expeditions at sea back home in Sweden.

 

What is your favourite thing about going on field work?

My favourite thing is getting the samples! It's a lot like looking for treasure; whenever the sampling gear comes aboard we're all very excited to see what is brought up with it. Even a heap of mud can cause quite a shuffle when everybody wants to see what's in it and pick out the things they work on.

Leigh-Marsh.jpg

What do you study?

I am studying for a PhD at the University of Southampton, based at the National Oceanography Centre, but I work with colleagues at the Natural History Museum. I use video footage taken by a remotely-operated vehicle (ROV) to study animals that live at hydrothermal vents.

 

What are you most excited about seeing/finding on the trip?

Taking REX into the Blue Hole. Who knows what we will find 200m down…

 

Where have you been previously on field work?

I have worked in the North Sea, English Channel and the Antarctic, so I am looking forward to working somewhere hot for a change!

 

What is your best experience whilst on field work?

Being one of the first people to see the hydrothermal vents in the Antarctic. They're not easy to find, but we managed to discover two new vent fields. This new discovery yielded several new species to science, including the much talked about 'Hoff crab'.

 

Is anything worrying you about the trip?

Working with electronics and water is always a risky business! Let’s hope everything is plugged in and water-tight!

 

What advice would you give to someone going on field work for the first time?

Take your favourite tea bags and your own mug!

 

-----------------------

 

That's it for today - tomorrow we'll meet the rest of the team.

Nick-Higgs.jpg

What do you study at the Museum?

I study animals that live on dead whale skeletons and how this affects the formation of whale fossils. I am particularly interested in the Osedax bone-eating worms!

 

What are you most excited about seeing on the trip?

I am really excited about seeing what kind of animals live in the deep water of the Bahamas. I grew up nearby and have always wondered what was living beyond the shallow water that I could reach while diving.

 

Where have you been previously on field work?

I have been to California, Japan and Sweden on field work before to study what happens to dead whales in these areas.

 

What is your least favourite thing about going on field work?

I’m really lucky be to able to travel to so many places as part of my job and I love it. But my least favourite thing is the preparation involved. Going to another country and bringing back samples involves a LOT of paperwork and planning, especially if you’re dealing with specially protected animals like whales.

 

Is anything worrying you about the trip?

I’m a little worried about not finding all of the experiments we prepared last time we were in the Bahamas. We dropped one very near an underwater cliff so let’s hope it didn’t fall down into the abyss!

 

What advice would you give to someone going on field work for the first time?

Remember that other people have different cultural backgrounds with different norms that you should respect. This is easy to forget when travelling to English speaking countries.

Diva-Amon.jpg

What do you study?

At the museum, my project looks at organic falls - these are large packages of food like dead whales and trees that sink to the seafloor. Once on the seafloor they provide lots of food and shelter for many deep sea animals and a whole new ecosystem is formed. My background is mainly deep sea biology but growing up in the Caribbean has allowed me to have good knowledge of tropical biology also.

 

What are you most excited about seeing/finding on the trip?

It would be incredible to find some Osedax worms on the bone packages we put down in October when we were last there, as they would be the first ones found in tropical waters. I’m also really looking forward to seeing some sharks as the Bahamas recently declared their national waters as a shark sanctuary.

 

Where have you been previously on field work?

I have previously done some field work off Bermuda and more importantly, I was part of the scientific team that journeyed to the Cayman Trench to discover the world's deepest hydrothermal vents. I've also done some work in my home of Trinidad and Tobago.

 

What is your best experience whilst on field work?

The best experience I've had while on field work would be when we saw the first live footage of the world’s deepest hydrothermal vents and the amazing animals living around them. It was so amazing to realise that our expedition were the first people on the planet to see this environment. I definitely shed a tear or two.

 

What advice would you give to someone going on field work for the first time?

Preparation is key - always have a back-up plan!

Adrian-Glover.jpg

 

What do you study at the Museum?

My main interest is deep-sea biology and in particular the diversity, evolution and ecology of the marine annelid worms - the polychaetes. These are incredibly diverse in the deep-sea, the least explored and largest ecosystem on the planet.

 

What are you most excited about seeing/finding on the trip?

Although our main science goal is the retrieval of a set of important colonisation experiments, I am secretly most excited about taking our little underwater robot 'REX' to its deepest depth rating - 200m. I would like to take it below the warm surface waters into the cooler, darker deep waters - the twilight zone - to observe the marine life using this new low-cost deep-sea approach that we are pioneering on this trip.

 

Where have you been previously been on field work?

I have been fortunate enough to be involved in field work all over the world. Mostly it has been in rather cold places (the Southern Ocean, the Antarctic and the North Sea). I am looking forward to a tropical trip for a change!

 

What is your best experience whilst on field work?

The best experience has been our first discovery of the enigmatic Osedax worms whilst on a sampling trip in Sweden. It was incredible to find these bizarre animals living so close to a marine lab, in shallow water. It reinforced to me how little we know even the accessible parts of our oceans.

Now that Tom has returned safely from his botanical trip to Costa Rica, I'll be heading off to the Bahamas with scientists from the Museum and the University of Southampton. Our destination is the remote island of Eleuthera in the Bahamas and most of our time will be spent on a boat.

 

google-earth-bahamas.jpg

(Click images to see them full size)

 

We’ll be using a Remotely-Operated Vehicle (ROV), called REX, to survey the fauna that live in this little explored part of the Caribbean. The really exciting bit is that in some cases this will be the first time that scientists have dropped a camera into these waters.

 

Aside from the observatory work, the team are also looking for a particular worm that likes to live on whale bones. Osedax worms have been found in every ocean in which scientists have looked for them, including the Antarctic, but will they also be found in the tropical waters of the Caribbean?

 

As part of the Museum’s Nature Live programme, I’m lucky enough be joining the trip and I’ll be sending back daily reports in the form of blog posts, pictures and videos. Get in touch with the field trip by using the comments section at the end of each blog.

 

For a chance to experience the trip come to the Museum's Attenborough Studio at 14:30 on 8, 9 and 10 March to see us in a live-video-link to the Bahamas.

It's Oscars time so please forgive me but it has to be done... the trip would not have been possible without the following people at the Museum:

 

The Learning Department and specifically Honor, Abigail, Martin and Stephen for letting me leave the office for a couple of weeks. Thanks!

 

The Nature Live team, particularly Jo Kessler for hosting the live-video-link events so expertly, and Ivvet Modinou, Natalie Mills and Ana Rita Claro Rodrigues for your support and good ideas. Also, thanks to Museum scientists Erica McAlister and Gavin Broad for being in the Studio to help prepare the ground with the audience for the live-video-links.

 

Tony and Adam in Special Effects for training me to use the satellite phone and other kit, coming to the realisation that I was likely to break it yet still letting me take it into a remote area of tropical forest in a completely different country (I hope you now feel it has been tested properly!).

 

To Jonathan for posting my blogs every day (even at the weekend) and for providing a forum for the live-chats we’ve held with UK school children as part of Nature Live in the Field - and also thanks to them and their teachers for some great questions and comments!

 

To Grace for developing the schools side of the project and for keeping me busy

 

In Costa Rica, a huge thank you to:

 

Our porters and guides in the La Amistad National Park, and Frank Gonzales at INBIO for sorting out the logistics of the trip and for providing me with a filming permit.

 

The rest of the botany team: Holger Thues, Jo Wilbraham and Neil Brummit - I hope I have been at least a little bit useful and that I have not wound you up too much with endless questions?

 

Daniel Santa Maria for my new nick name!

 

Finally, to Alex Monro for organising the trip and my part in it. I have had a wonderful time and I am so thankful to you for giving me this opportunity to follow science as it happens in the field. Thank you!

 

Day 17 PIC 2.jpg

 

I asked the scientists what they thought….

 

 

P.S. This is not the end for Field work with Nature Live as, starting from the 7 March my Nature Live colleague Ivvet Modinou will arrive in the Bahamas with a team of scientists to report on a field trip exploring the life in our oceans. It should have some great footage as they'll be using a mini-submersible in their research!

 

Keep in touch with the Field work with Nature Live community and subscribe to the RSS feed for this blog and you will receive updates whenever a new post appears.

 

And remember, you can meet more Museum scientists every day at Nature Live events held in the Museum’s Attenborough studio at 14:30 (and also 12:30 every weekend and throughout the holidays).

 

I hope to see you at a Nature Live event soon!
