Follow up…

September 8, 2009

You may be wondering what’s happened since the end of our Arctic trip, so I thought I’d write a short post to keep you updated.

The short story is that many of us are still analysing data and writing up our results. Once scientists get back to “the real world”, like everyone, we have lots of other things to deal with. It is a bit of a shock to the system coming home after a long field trip or a research cruise. Not only do we have to integrate ourselves back into normal society but we have to get back into the routine of working, cooking, cleaning and attending to family needs. We have been a bit spoilt being in the Arctic, because we are taken care of – all our cleaning and cooking is done for us, so we can just spend all the time focussing on enjoying the science.

I would like to update this blog with some of the interesting results that will hopefully come out of this trip. The information should start coming out soon, so as soon as it does, we will get the information out to you. Watch this space…

We had the first EPOCA annual meeting in Plymouth at the beginning of July and it was a good opportunity to catch up with everyone from the trip. This was quite a mixed meeting, with lots of session dealing with project management and how everyone was getting on with their individual role in EPOCA. But there were a few snippets of science data as well. The concern over the Arctic ocean was one of the most relevant – cruise and model data suggesting that continued emissions of CO2 will result in the Arctic becoming undersaturated with respect to aragonite (the mineral pteropods and other shelled organisms use to form their shells) by the year 2030. Steeve Comeau’s work on pteropods from last summer in the Arctic showed that pteropods seem to be affected by these changes in aragonite conditions, so that doesn’t look good for them. Other work is showing that the double whamy of temperature and ocean acidifcation are going to cause complicated interacting impacts. And although ocean acidifcation is no doubt important, we should not forget the multitude of other stresses that humans are forcing on our fragile environment.

Going home

June 1, 2009

We have had an eventful last few days in the lab. The sediment experiment finished on Thursday, so Bonnie and Lara spent a long day in the lab slicing sediment cores up so that they could take home samples for analysis. On Saturday the urchin experiment finished so Hannah, Bonnie and I (with help for Lara, thanks!) spent a good number of hours taking more samples from the last set of urchins. Axinja and Sandra moved their experimental tanks over to the small experiment room, where the nutrient experiments had been; and by dinner we had completely cleared the large experiment room ready for packing and tidying the next day.

We had a bit of free time on Friday to relax in between all the experiments, so Lara, Bonnie and I took a walk down the fjord to visit Corbel. Corbel is an extension of the AWIPEV base – a few small huts grouped together about 6 km down the fjord from the main village. At the moment there are about 5 or 6 French scientists working there. They work on a mix of different topics, ranging from glaciology to ornithology (studying birds – there is a large cliff nearby where many of the gulls and terns nest). They started to build the huts last September and are now adding a few more solar panals and testing out a wind generator so that they are completely self sufficient for energy. The idea is that the scientists are a lot closer to the things that they study, and save time and energy travelling back and forth between study sites.

Sunday and Monday have been our packing days. Steeve, Axinja and Sandra are staying some extra time so that laboratory is not too empty but it feels strange having an empty experiment room again. Our last day is filled with beautiful sunshine so once we have packed we are going to go enjoy our last afternoon in the snow and sun.

Search for the sea butterflies…

May 25, 2009

This last week has been a very routine week in the lab. Most of our time has spent taking samples of the water conditions in our experimental containers, sampling the urchin blood (see Hannah’s blog), measuring turnover rates (see blog) and carrying out fertilisation experiments (again, see Hannah’s blog but also check out the study 10 page for a video and update). So this weekend we were very organised and managed to get all our main sampling done so that we could have a bit more time to see the area around the base while we are here. It seems a shame to come all the way to the Arctic to then spend all the time inside a laboratory!

On Saturday we joined Steeve on his search for Pteropods. Steeve has not been having much luck in getting these tiny floating snails so far (they look a bit like butterflies because they use their foot a bit like wings). Last week he managed to take the boat a little bit further out of the fjord and found an area where he collected around 80 or so of these creatures; so on Saturday we went back to the spot to find some more. This involved taking out two small boats and driving about 15 km from the base out of the fjord. It was an extremely calm day but our early start meant that the mist was still covering the fjord and although the water was as flat as a mirror it was a little spooky speeding out into the mist in our boats. As the mist lifted we were treated to amazing views of the bright blue glaciers creeping up to the waters edge surrounded by dark mountains.

Once we arrived at the site, we switched off our engine and let the boat drift around (we were the support team in case anything went wrong) while Steeve and his crew got on with sorting out the plankton net and buckets. Collecting pteropods is a bit of a fine art, they are quite small and delicate so the plankton net was lowered gently down about 50 m in the water and then slowly bought back up again. Steeve retrieved the large container from the end of the net and carefully plucked out any pteropods.

After about 5 or 6 plankton tows Steeve had collected over 40 pteropods, which is still not enough for his experiment but our time was running out – every time we leave the base we have to take a radio, a rifle and a flare gun, as well as inform someone on base what time we will be back and where we will be going – so we headed back to base. Snow was still falling as we returned, even though the mist had lifted but there were still no waves and just the wind from the boat keeping us cold. We saw quite a few birds, lots of fulmars, some skuas and even some puffins. I’ve got a video to put up soon and they will feature in that.

The weather has turned again now. The sun came out on Sunday for the first time in about 5 days and we had a beautiful but bitterly cold day. The wind picked up throughout Sunday afternoon and by the evening it was snowing again. This morning we woke up to more snow and strong winds, it is now minus 7 ºC but with wind chill it is down to minus 22 ºC, which is the coldest it has been since we arrived. The divers cannot go out and Steeve has to wait another day to continue his search for the sea butterflies…

Living in the Village

May 10, 2009

Hannah and I spent the other night making a video about Ny Alesund and some of the aspects of life on a research base…. its a little bit random but shows the main buildings in the village, the rooms we sleep in, the Huskies, the mess where we go to eat and some other bits and pieces…

Ice is nice but wetter is better…

May 9, 2009

Sea ice is very dynamic, it is constantly changing, and is very quick to change. You’ll have noticed that when we first arrived in Ny Alesund the fjord was completely full of sea ice – very nice for photos but not a good start for trying to collect animals and sediment…

Frozen fjord

At the end of the first week the ice breaker had come in and broken up the ice. Luckily  this was followed by an easterly strom-force wind, which blew the broken ice out the fjord – maybe we’ll get some experiments going after all…

Fjord opening up during the storm

This was good news because we were able to launch to the dive boat. However storms don’t last forever and there was still a lot of ice in the fjord. The last few days we have had very nice sunny weather but this has made everything quite cold again – its been between -2 oC and -5 oC. We woke the other morning to find the fjord re-freezing, and the dive boat in the middle of it – oh dear, and still not a mud sample in sight…

Dive boat stuck in new "pancake" ice

Sea water freezes at about -1.8 oC but the exact value depends on how salty it is. When it starts to freeze it happens in small patches which slowly grow outwards and look a bit like lilly-pads or pancakes (in fact it is called pancake ice). When they get big enough they bump up against the neighbouring pancakes and these then get thicker and thicker and melt and freeze together. Sea ice can crack down these joins quite easily and this is what forms leads or paths in the ice, which ships can use to pass through.

In the distance we could also see that the thicker, whiter, sea ice was starting to block up the end of the fjord as well as new ice forming nearer the shore – I’m getting a feeling of de ja vu…

Freezing fjord

And so the game begins again… This afternoon it has slowly got more stormy, the wind has picked up (easterly again) and the ice is being pushed out and the divers are doing their best to keep us happy – the sediment might be here by this evening, then its only another few hundred serripes, urchins and gastropods left for them to collect, no problem!

The cargo arrives…

May 7, 2009

Ny AlesundAfter much waiting and hoping, the cargo ship finally docked at Ny Alesund on Tuesday (5th May). It arrived around 8 am and didn’t finish unloading and reloading until about 5.30 pm.

This was great news for us because many of the scientists still had several boxes of equipment that they had been waiting for so that they could start carrying out there experiments. Unfortunately there is still a few bits missing but hopefully by Monday we should have a full complement of equipment!

It was also very exciting because this is the first ship that has arrived in Ny Alesund since December and it brings with it much needed new stock of food and drinks. The base has been relying heavily on frozen and preservable food as well as the odd plane load of food but the variety of food soon gets a bit limited! So we now have fresh fruit and veg, salad for lunch, yogurts for breakfast and lots of eggs!

The final and possibly most important aspect of the ship’s passing was that is made way for us to launch the dive boat. This was great news for us because many of the studies have been on hold waiting for access to the boat so that animals and sediment can be collected. Hopefully there will be fewer problems now, although the fjord is still very icey and not all the dive sites are ice free yet.
