Researching polychaete worms in the Falkland Islands

In November 2011 I visited the Falkland Islands to start a project looking at the distribution and identification of the marine bristleworms (polychaetes). The visit was part funded by the Shackleton Scholarship Fund and, following a highly successful visit, a second grant was awarded in April 2012 to fund a second trip in January 2013. The additional fieldwork will concentrate on the island of West Falkland which was not sampled at all on the last trip as well as visiting a few extra sites on East Falkland to gain more comprehensive coverage of that island too. The combination of the two trips together will provide data from all around the coasts of both islands as well as Falkland Sound in between them and will be the most detailed survey of the polychaetes of the intertidal and inshore regions for that area to date.

Check back regularly to see what I've been up to.

No sampling today and very glad I was too as a torrential hailstorm (photo 1) battered the office windows! A third parcel is now with the post office and will hopefully be winging its way up the Atlantic by the end of the week. The rest of today has been spent preparing for my trip to West Falkland tomorrow. I will be over there for 10 days touring my way around the island to try and get as good coverage of the shoreline as I can. As my choice of shores is largely dictated by the existence of roads by which to reach them and places I can stay my choice of sites was fairly restricted but I think I have a fairly good itinerary.

The ferry goes from New Haven to Port Howard in the evening which gives me time to catch the tide in New Haven just after lunch (why miss an opportunity?!). I’ll then be travelling south down the east coast to Fox Bay, further south and west to Port Stephens before turning north to South Harbour. From there I keep heading north this time up the west coast, stopping in at Chartres and Roy Cove before reaching Dunbar in the northwest. From Dunbar I will move along the north coast to Hill Cove, West Lagoons and Shallow Bay before heading back to Port Howard and digging a few holes there for good measure. Then its back to Stanley, get the last parcels on their way home before packing myself off too. Photo 2 shows the locations of the various sites.

It will certainly be interesting to visit the shores on the west and see if there is any obvious difference in the fauna there, particularly as I get up to the northwestern areas. That part of the islands is affected by more northerly temperate currents rather than the colder southerly currents dominating the southeast so potentially there may be many different species there.

Internet access is unlikely for most of the tour although I am hoping to be able to send short updates for the blog whenever possible by text to report any notable events!

Yesterday (Monday) was probably the warmest day so far. Not necessarily the day you would pick for a dusty 3 hour drive across the island but that’s how it was. I was very thankful that the car had working air con as you can’t open the windows while driving unless you want the interior to be caked in half an inch of dust when you arrive. The timings of the tides meant that I would be able to catch both an evening tide and then a morning tide too, getting 2 sites done in the area. Unfortunately the tides at the moment are not the biggest so there is less beach exposed and available for sampling. Still at least I would get something - or so I hoped - North Arm turned out to be a very poor site for polychaetes indeed.

Monday night I picked a small creek just before the settlement (Photo 1). Rocky around the edges, the sheltered aspect meant that much of it was made up of very soft muddy sediment, the kind your boot sinks into and then stays. However, I found I could move around so long as I didn’t stay still too long but despite several attempts I was finding very little in the soft mud. Eventually I started finding some lugworms but by the end of nearly 2 hours I had found little else even though I had tried several places around the creek. It certainly made for a less arduous evening’s work than usual anyway.

The next morning, I tried the shoreline at the other end of the settlement. This proved to be very rocky with extensive mussel beds (Photo 2). The areas outside of the mussel beds had very coarse loose sand that again seemed to harbour very little in the way of obvious animals. However, I collected what I could find and then washed and sieved some of the sediment through a 0.5 mm mesh sieve. This is our standard way of getting a more complete view of the life in the sediment as the smaller worms will ‘float off’ in the swirled sediment and then be held on the fine mesh of the sieve as the water is poured through. The residue on the mesh is then washed into a pot and kept to be later sorted through under a microscope when any tiny animals can then be picked out. I did this for the general sandy sediment and also for some samples of the mussel beds which I washed off in a bucket and then poured through the sieve also. Hopefully there will be many more animals in there that I hadn’t been able to see without a microscope.

The long drive back then beckoned followed by more washing of previous samples and transferring them from formaldehyde to ethanol. Tomorrow I will be able to pack more pots and get at least one if not two more parcels of specimens on the way back to the UK. Photo 3 shows where North Arm is in the Falkland Islands.

The weather today has been absolutely glorious. I realize that most people reading this will probably hate me for saying that, due to the current weather in the UK but it’s true. Managed to get out for a local dive this morning, a little further up the coast near York Point, east of Cape Pembroke. The dive site was a small rock rising a couple of metres above the surface (photo 1). It was only very shallow but there was an amazing amount of life on the colourful reef, including, most importantly of course, worm life. The main downside of sampling underwater out here is the prevalence not just of kelp, but of giant kelp (photo 2). This stuff gets everywhere, in your face, round your legs and just generally in the way!

One of the reasons we had gone there was so that I could see and sample some Phragmatopoma reef (as mentioned in the previous blog) and although not large we did find some (photo 3). There were also many fan worms (photo 4), another large worm known as the parchment worm (Chaetopterus sp.) for its thick papery tube and a colony of other smaller, thinner-tubed worms (photo 5) in the same family but a different genus to Chaetopterus.

Sadly, that one dive was the only one we did but I have enough work to keep me going into the evening now looking through them.

Tomorrow, I am heading south to North Arm, the southern-most settlement and furthest south the road goes on East Falkland. The tide times are such that I will be able to make both the evening and the next morning tides in order to get plenty done before heading back to Stanley on Tuesday.

19.01.13: I’ve just come back from 2 days out on Saunders Island, one of the larger outer islands in the north west of the area. The island is host to a mountain of wildlife and I was hoping to see lots of this while at the same time being able to continue my sampling on such a distant point. Although I was staying in the settlement on the east coast of the island, the owners gave me a lift to one of the more northern parts of the island known as The Neck (photo 1). This is a narrow stretch of land with sandy bays to the north and south so the idea was to try and sample both sides and be able to compare them. The low tide was not until the evening at 7.30pm and the owners generously agreed to come back and fetch me at 8pm so I would be able to do my sampling (it’s a 10 mile hike back to the settlement from there). The late tide also meant that I had time to do some walking of my own and visit the different penguin colonies in the area: Magellanic, Gentoo (photo 2), King and Rockhopper, all charming as ever particularly the curious gentoos who will come right up to you if you sit down and wait patiently. I was also surprised, and not a little dismayed, to find a large population of caracaras (photo 3) in the area, not my favourite bird as many will know. Any time you stop moving or put anything down, however briefly, a caracara will almost immediately turn up and start investigating, poking things with a very sharp talon to see if its worth flying off with.

Once the tide was about half way out on the north beach I set about poking around with my trowel. Nothing. Hmm. More holes, still nothing. This wasn’t good, the clean white/grey sand beaches the penguins are so fond of is obviously very bad for worms. I found nothing at all in the high shore region so tramped disconsolately down the beach before deciding to go and try the south beach. Nothing. Another hole, still nothing, the caracaras were shadowing me, either hoping or expecting me to give up and drop dead at any second. As I plodded along this beach my eye was suddenly caught by a discrepancy on the surface. Looking closer the little grey spots looked like small worm casts, so out came the trowel. Success! I was so happy, I wasn’t going to leave with nothing! There weren’t many but I did manage to collect a small variety of worms, always keeping a sharp eye on anything I put down and occasionally having to shoo-off the insistent thieving birdlife. As I moved further down the shore with the tide, the casts became slightly more common and I felt that at least I would have a representative collection for the area. Beaches are not always teeming with worms and this was obviously one of those. At the end I went back over to the north beach to see if I had missed those small signs of worm life. I still couldn’t see anything but had a dig down at low water and did find a sparse population of worms to collect. The worms in this habitat apparently only inhabit the mid-low shore and not high shore at all.

The next day, blessed with blue skies and warm sunshine, I planned a hike up the east coast towards a sandy bay one of the owners had told me about where he said he had seen evidence of worms before. I knew it wasn’t close and 2.5 hours later I made it. As low water had been early morning I knew I wouldn’t be able to sample properly but at least would be able to do a bit from midshore upwards. I stared in dismay at the billions of tiny worm holes (photo 4) on the surface of the soft sand. The only way to do this beach justice would be several hours and a large spade, neither of which I had. With the tide rapidly encroaching I did what I could before retreating. I realized there was not a single penguin to be seen on this beach. It would seem that penguins and worms do not mix, a good beach for one is a bad beach for the other. I continued my hike a short distance further so I could see one of the other main highlights of the island, the black-browed albatross colony (photo 5) that breed here, then I headed back.

I used the late tide that night to investigate the local harbour 5 minutes from the settlement, happily poking around the mud and rocky foreshore. Amazingly, there were many polychaetes (family Cirratulidae, photo 6) sitting right out on the surface of the mud all over the place. Under the flat rocks of the foreshore I found large white sipunculans (photo 7), relatives of the polychaete group and a species of polychaete that I don’t think I have had anywhere else, a definite highlight for the trip.

Saturday (today) saw me return to Stanley with my haul and I then spent the rest of the morning doing more formaldehyde washing-out from last weeks specimens and packing my first box ready to post back on Monday!

Falkland Islands 2013: January 17th update

Posted by Peter Howlett on 20 January 2013

16.01.13: There was no sampling planned today but instead I took an opportunity to look after the samples I took on the first 2 days out. My samples are always ‘fixed’ in formaldehyde to preserve the animals properly for later investigation but formaldehyde is acidic and it is not good to keep specimens in the fluid for too long. After at least 2 days being ‘fixed’, they are washed with freshwater to remove the formaldehyde as well as the salt from the seawater and then placed into 70% ethanol for better long term preservation. The last time I was here I left this job until the last few days of stay and then it took me a very long time to get through all of the samples. This time, particularly as I do not have much time between the end of sampling and my flight home, I am trying to be more efficient and do this job roughly every week which means it will be fairly quick each time and I can then also get the samples packaged up and sent off at intervals. This in turn avoids trundling multiple boxes down the post office and seeing the horror on the person’s face as they peer over the counter at the pile on the floor to be processed for recorded delivery!

The next job on the list was to start writing the public talk I will be giving next week at Government House here in Stanley. The talk is on the progress of the project looking at the polychaete life in the Falkland Islands and will give a summary of the results so far from the last trip, including details of three new species discovered, as well as the purpose of this trip and where I will be visiting while here. Hopefully anyone who comes along will agree that the work is well worth doing and producing important results.

Unfortunately, the diving expedition I was due to go on for the next few days has had to be cancelled due to others being unavailable although I am promised some diving at least on Sunday if not Saturday as well. Instead I have planned a last minute trip to one of the outer islands, Saunders Island. Like many others, this island is a nature reserve although the owners have given me permission to do some extra sampling there. This will be part leisure as well as getting extra sampling in (never travel without your trusty trowel, sieve and pots) and I am looking forward to seeing some penguins again. This will also be the farthest north I get to on this trip and as such an important addition to the route. Wifi does not exist that far out so no updates until the weekend (or after).

Due to a technical hitch the sampling at Whalebone Cove was postponed. Low tide was in fact 2 hours later than I thought as I had subtracted rather than added 1 hour for summertime, oops! Instead I got on the road to make the tide in the north (which I had worked out correctly). Three hours in the car brought me to Race Point Farm near Port San Carlos. This is in the northwest of East Falkland and had a very rocky shore with some large crevices in the rocks. These crevices could be split open with a spade and inside, hiding in the built up silt, were some very large worms indeed of the family Eunicidae (also known as ‘bobbit worms’ – google the phrase and you’ll find some footage of relatives of these worms hunting). The biggest of these measured around 20cm in length and as these worms have jaws I kept my fingers well away from the bitey end! The wind was whistling around the shore and despite being summer, my fingers were certainly cold. There was plenty to find though with colourful paddleworms being particularly common (photo 1). My bed for the night was a surprisingly cosy caravan at Elephant Beach Farm slightly further north. Despite how this sounds it really was comfortable, being fully equipped with power, hot shower and cooker and, even better, a freshly baked loaf of bread and some fresh eggs from the hens outside my door to keep me going.

Port Salvador was the next port of call and after calling in on the landowner, Nick Pitaluga, for a chat, he very kindly offered to drive me up to near Cape Bougainville right on the north tip of the coastline to sample there. This had originally been where I wanted to go but the road does not go that far and I had no desire (or permission) to take the hire car off road. The bone-rattling drive there, mostly on a visible track but the last part just generally cross-country toward the sea, confirmed that I would never have made it even halfway there without a guide. The exposed coastline was unsurprisingly rocky with long ledges of rock running out from the shore (photo 2). The tides are very low right now and the ledges were exposed right down into the kelp zone, where the enormous blades (nearly 1cm thick) of Lessonia kelp draped themselves over the rock and were so heavy they could barely be moved out of the way (photo 3). Underneath, in the cool damp crevices I found long tubes cemented to the rock. These turned out to be the home of large sabellariid worms (Phragmatopoma sp. photo 4), a relative of which lives in the UK and is known as the honeycomb worm for the tubes and occasionally reefs, it builds. Out here, this worm also sometimes creates reefs although here the tubes were individual. The worms inside are large, over 5 cm in length. I didn’t find any specimens of this family last time I was here so this was a very exciting find for me. Several scaleworms were also found sheltering in the crevices (photo 5).

On the drive back to the settlement I could see the sandy shores near it now exposed by the tide. These looked interesting so I decided to go back to the area the next day to do some digging there. This turned out to be a very rich beach and it was easy to see why there were so many wading birds around. The shore was literally covered with worm-holes and casts (photo 6) and I spent 3 hours working my around and down the shore with the tide. The weather by this time had changed from occasionally sunny (constantly windy) with a need for suncream even though I was feeling mildly hypothermic to mostly sunny with a feeling that I really might actually need the suncream (still windy).

On the drive back to Stanley that evening I felt that the first few days collecting had gone well. My main current concern is the fact that everyone I meet keeps trying to feed me either tea and cake or tea and biscuits (occasionally both). I have now given up on my post-Christmas attempt to wean myself off sugar.

On Wednesday I made it to Whalebone Cove having now worked the tides out properly. Amazingly the wind had dropped (not stopped obviously) which helped the tide go out as low as possible. This was important because I was after some particular lugworms that are only found at very low water. I found these last time and they appear to be different to the others higher up the shore. However, I didn’t find very many before so I needed to collect more to be sure that differences I see are not just natural variation but a definite consistent difference in body form. The wind and tide were kind and allowed me to get what I needed so then it was back to the lab to inspect my catch. Photo 7 shows a map with the locations of the sites mentioned above.

South Atlantic Environmental Research Institute, created in 2012.
The pilot managed to jam the wing tip under the wing of the only other plane on the ground!
Map of the Falkland Islands showing sites where sampling was carried out in 2011.

It hasn’t been the best start. It’s never a good sign when your plane stalls on the tarmac while taxiing to the runway and everything goes dark. As calls of ‘get the jump leads out’ echoed around the plane, the pilot turned the key again and off we flew, landing at Ascension Island 8 hours later. Sat in the middle row of seats I was unaware of the events outside the plane but as we stopped the pilot, with a slightly embarrassed tone, announced that we would be delayed getting off the plane. It quickly circulated, from those that had witnessed the event, that our wing was now jammed under that of the only other plane on the tarmac. Great. The next 12 hours were a long story that involved our plane being declared unserviceable (after being separated from the other plane) and then, surprisingly and not a little worryingly, it was suddenly serviceable again, we were herded back on and on we flew. The landing at Mount Pleasant airport was mildly bumpy in the gale force winds that greeted us at 1am, 10 hours later than originally due but at least we were there.

This time I am based at the South Atlantic Environmental Research Institute (SAERI) in Stanley, a new organisation that was created in early 2012. Its objective is to be a world class academic institute, based in the Falkland Islands, operating in the South Atlantic from the equator down to the ice in Antarctica, conducting world class research, teaching students, and building capacity within and between the UK South Atlantic Overseas Territories (UK OTs). The institute’s remit includes the natural and physical sciences (see http://www.south-atlantic-research.org).

Today I am just sorting out my itinerary and equipment and visiting the different facilities I will be using while I’m here. Then from tomorrow I’ll be back out on the beaches chasing worms. The first stop will be Whalebone Cove, a bay just outside Stanley that I visited last time. The lugworms I collected from there turned out to be very interesting indeed with a potentially new species involved and I would like to see if I can investigate those a little more. Then it’s a drive to the northwest for an afternoon tide.

It’s extremely windy here at the moment, even more so than usual, so I am hoping that this drops a little. It is sunny and warm though which is a nice change from the wet and grey weather I left behind and much better for sampling in.

The map of the Falkland Islands shows the sites I visited last year - this year I will mainly be sampling on the West Falkland.

Adélie Penguin in the Museum's collections
Adélie Penguin in the Museum's collections. The Adélie Penguin is the only other truly Antarctic penguin. It is about half the size of the Emperor Penguin and weighs between 4 and 6 kg. Adélie Penguins look as though they are being affected by the climate change happening around the Antarctic Peninsula. Adélies only occur where there is plenty of pack-ice in the sea. As the peninsula has warmed there is now less pack-ice in the height of the summer and the Adélie Penguins appear to be moving further south to stay with the pack-ice.

This morning I presented my last talk to the Fisheries Department which was about the methods of collecting and identifying polychaetes. It seemed to go down reasonably well and then I handed back my key and left for the last time.


My samples are now officially with the Post Office hopefully to be on their way back to the UK shortly. As for me my journey back starts at 5am tomorrow morning. It will already be daylight then and will be the last time I see daylight at that time of the morning for a few months to come. Arrival back in the UK is likely to be a bit of a shock for me I think as there is currently around 8 or 9 hours less daylight there each day than here and the weather is now decidedly wetter and colder. Shortest day is fast approaching in the UK with longest day due here next week. Ah well.


Several weeks ago I pointed out that my challenge would be to still be finding new animals on Day 28. By my calculations that would actually be today so I failed there as there has been no new sampling since Friday which was Day 25. However, as I did have a new worm that day, from my final site, I think that’s pretty good going!


My sampling here has gone well and I’m really pleased with the variety of animals I have been able to collect. I’m looking forward to being able to spend some time looking at them in more detail in the New Year. I’ve enjoyed my time here and had an amazing opportunity to visit a place and see things that many others won’t get a chance to and I appreciate how lucky I’ve been.


I know that some of the people I’ve meet here have also been reading this blog and I’d like to take the opportunity to thank everyone involved for all of the help I’ve had getting out here and during my stay, from loaning me cars to get around to coming out on the shores with me or taking me diving to get more samples. This trip wouldn’t have been nearly as successful without all of your help.  

 
The Shallow Marine Surveys Group, whose survey work I piggy-backed to go diving, do a fantastic job out here with their dive surveys, mostly as volunteers with a few grants to help with costs and the Fisheries Department allowed me free run of their lab at all hours.


Not least of course I must thank the Shackleton Scholarship Fund and National Museum Wales who have funded and supported this visit.


Thank you all!

My directions turned out to be accurate and easy to follow and I arrived at Teal Creek in plenty of time for the tide. The biggest problem I had was deciding where to stop along the creek. At the time I arrived the tide still had a way to go out so it was difficult to know how much ground would be uncovered. I made my decision and walked out into the small inlet off the creek (photo 1). The area was very soft but the depth of the mud varied and I didn’t venture too far into deeper areas, wary of getting stuck. As I dug around I was surprised to find the same new ragworm that I had found at Sand Bay the previous day, having not found it at any site before and now two in a row. There were also many of the bamboo worms that seem to dominate the shores here.


I left the creek shortly before actual low tide in order to give myself time to get over to Camilla Creek where low tide would be in just over 2 hours time. The tide hadn’t gone down much for a while so I didn’t think I would be missing anything new being uncovered.  As I drove out past the previous choices I had had for stopping in the area I realised that the earlier bays had much larger areas of mud flat exposed and I thought maybe I had made a mistake in my choice of sampling site. However, on reflection, the water had retreated to the far side of the creek from these bays and that would have left me with no access to water across the mud which is essential during the collecting, so I probably did make the right choice after all.


Camilla Creek was reached fairly quickly with some expanses of mud flat already exposed. It was a much larger, wider creek (photo 2) than Teal but the shore itself seemed more gravelly leading down to it. I quickly realised that although the approach was easier, the mud itself was softer and deeper and probably not to be ventured too far into without additional company for safety and better sampling gear than what now felt like a very short pair of wellies. After extricating myself from the mud I skirted around the edge of the water level in the small bay sampling different spots and finding quite a variety of different mud, sand and hard areas to try.


Eventually it was time to leave for the journey back. This time I kept the window tightly shut and arrived back slightly less dusty than the previous night. There was at least one new worm for my list from the samples in the form of another different paddleworm (photo 3).


Saturday saw the last of the formaldehyde to alcohol changing where possible. The later samples would all have to stay in formaldehyde though as they needed to stay in that fluid for at least a few days to make sure they were properly ‘fixed’ before being moved to alcohol. That will now be done after both I and they arrive back in Cardiff. This was then followed by several hours of painstakingly sealing and taping around the lid of each pot and then sealing them into bags in order to reduce the risk of any fluid leakage during transport. As there were around 200 pots to do this took a while! The photo shows all of the pots at various stages of packing.


This morning (Sunday) saw a few more hours of sealing and packing until I had 7 boxes of packed samples ready for posting tomorrow (I can’t bring them back on the plane with me sadly).
There had been plans to do a last shore dive locally this afternoon but unfortunately the wind has scuppered our plans, blowing strongly all day. As it would have been a shallow site with entry off the shore, the windy conditions would have made getting in and out of the water difficult, conditions underwater uncomfortable and visibility poor, so an obvious decision was made. Still disappointing though as everyone had told me what a lovely dive it was going to be!


Tomorrow’s plan includes my final talk at the Fisheries Department in the morning followed by getting those parcels on their way and then getting my own packing started. Only one more day left here!

Wow, what a glorious day! It’s a bank holiday here but unlike most in the UK, a bank holiday with fantastic weather. The temperature is 18degC, that may not sound that high but it feels very warm and the burn factor is quite high. It’s been strange driving along listening to the radio reporting the weather in the UK which I hear is particularly bad right now. I am very thankful for being where I am!

This morning’s sampling site was Sand Bay, near Port Harriet, about a half hour drive out of Stanley. The bay opens out quickly to a wide area of sand (photo 1). The sand varies quite widely across the bay from very coarse to fine, sometimes with gravel or rocks and in other places just sand. The animals themselves also seemed to change accordingly so it was worth dotting my sampling sites around the bay.

Although at first this bay didn’t seem that much different to several of the other sites I’ve been to, a couple of the samples turned up some very different animals.

The most interesting was in a patch of the ‘solid’ sand, no stones but with some layers of old plant material as you dug down. Burrowing into those layers were a different sort of ragworm to any of those I’ve seen in any of my other samples, with striking red and white colours along its body (photo 2). I spent a while collecting several of these as they were obviously a different species to those I already had.

There was also a different type of paddleworm, the longest yet (photo 3), from one of the other sample spots. I only found one of these though.

By the time the tide turned, I had a large collection of pots from the different sites around the bay and a few animals that I already knew would be new to my list. As I wanted to get some photos of the ragworm with its colours I decided to go back into Stanley to the Fisheries lab rather than head straight out towards Darwin. I wasn’t that far away and it was worth the time. After a quick photo session I then got back on the road again, back out past where I had already been that morning and on to Darwin which would be nearly a 2 hour drive.

As it was such a warm and dry day I had the window open slightly but wasn’t prepared for just how much dust was created driving along the gravel roads. It was only when I arrived here at Darwin that I realised that the car, both inside as well as out, and myself, were coated in the dust.

I have been given instructions on how to get to the two creeks I want to sample tomorrow and hopefully they will also provide some interesting finds to end the week.
