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.

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.

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.
