Today was a big day all round, and it started grey and snowy, with feelings of tense anticipation. For the scientists, it’s the next step towards the work they’ve put so much effort into over the last up to four years. If the mesocosms can be put in place successfully, they can lower the sacks and close them up to start the world’s biggest experiment on ocean acidification. If not, they’re in a bad way.
For the Greenpeace team, it’s time to put the giant testtubes they’ve carefully brought up to the Arctic from Kiel in Germany into the water, the fruition of their work with the scientist team. It’s a premiere all round. Not only is it a new and large-scale experiment, it’s a premiere in terms of Greenpeace and an official science body working together. As Martin Kaiser, Greenpeace climate campaigner from Germany and Professor Ulf Riebesell explained to me, the memorandum of understanding stipulates clearly who does what. The scientists are independent, doing their own work, grateful to Greenpeace for providing the boat without which none of this could have happened. Greenpeace is responsible for the logistics and helping because they want the data on the effects of ocean acidification on Arctic ocean ecosystems and organisms to be collected. Everybody stresses there are no foregone conclusions. Lab tests have indicated calcifying organisms are likely to suffer badly, but only this bigger experiment will give an indication of how whole systems react.
Let me give you the rest of the day in pictures.

The crew on the Esperanza were up bright and breezy and ready to start loading the mesocosms from the quay onto the boat at 8. Well you can’t say crack of dawn, since it’s light all night.
The scientists were down to keep an eye on operations

and IFM Geomar engineer Detlef Hoffmann, who seems to me to have been spending his life going up and down in the lift fixing up the mesocosms was back in place.

One by one, the first 3 mesocosms were lifted onto the Esperanza.

Professor Ulf, who’s coordinated the experiment, and Klaus, who designed the mesocosms, watch anxiously from the deck of the Esperanza.

At the deployment site, number one goes over, steady as she goes…

In the scientists\’s boat, Prof. Jean Pierre, the EPOCA coordinator,keeps an anxious eye.

The IFM technical experts in the dinghy do the necessary to affix the equipment.

Having “suited up” and gone into one of the Greenpeace dinghy, I’m able to follow the next “mesocosm overboard” operation from the water, looking up to the Esperanza.

The Greenpeace communications team are busy documenting this slightly different “campaign”.

Down she goes…

Well met, IFM Geomar.

Ulf has got on his survival gear and come down to check it out for himself.

And Greenpeace climate campaigner Martin Kaiser, on board the Esperanza, can be happy with the results so far.

Before I go any further:
Professor Jean-Pierre Gattuso, the coordinator of the whole EPOCA project, (see last blog post) has drawn my attention to the websites for the EPOCA project and suggested Ice Blog readers might like a look, so here they are. Thanks Jean-Pierre:

Sunday afternoon: the plan is to deploy the mesocosms in the fjord Monday morning if the weather remains stable. So Sebastian Krug from IFM Geomar, who is responsible for the logistics of the deployment, took some of his colleagues out in a boat with a remote-controlled underwater camera

this afternoon to check the anchors which have been put down to hold the floating test-tube constructions and make sure the lines coming up are not tangled and everything is where it should be. I was able to join them.
We need survival suits for this as the water is around freezing point. Everybody gets a briefing on the dangers of hypothermia up here, which sets in very quickly if you fall into the water without a suit, and nobody takes any chances.

Sebastian’s colleagues Andrea Ludwig, Sine Klaasen and Kai Schulz from IFM Geomar, the Kiel University marine science institute that’s managing all this, are also doing test runs with their equipment to take water samples and transport them back to the world’s most northerly marine lab in the base at Ny Alesund. They will be doing this with samples from the mesocosms regularly, once they’re in place and have been “dosed” with the required doses of CO2, a different amount in each mesocosm to simulate, in situ, what would happen if the ocean acidifies to a particular amount, according to the different IPCC scenarios, depending on how much CO2 we continue to emit in the coming decades. Kai is responsible for adding the CO2.

It started off as a grey day with snowflakes, but the sun came out surprisingly in between. The weather changes quickly and frequently here in the Arctic. You have to make the best of every sunray.

Thanks Meike.
We got close up to this iceberg in the fjord. Hoping it and its colleagues will keep a safe distance from the mesocosms site.

Our little friend did his work underwater.

He makes some interesting blubbering and spitting sounds as he goes down (which you’ll hear when you tune into the radio stories on this project some time in the not too distant future! Keep an eye on the DW website and Living Planet

Nathan (Living Planet host), I hope you have plenty of space for this one, it’s a very exciting project.
The anchors are looking good, so weather and ice permitting, it’s full speed ahead for deployment on Monday morning. The scientists are getting excited, some nervous. They’ve been working for several years preparing this and it is the first of its kind. The crew on the Greenpeace boat are also excited about it all. They are playing a key role in getting this world premiere on the stage.

We didn’t get the usual 7.30 morning wake up knock on the door this morning, a Sunday treat.
Still, when I looked out onto the pier, Professor Jean-Pierre Gattuso, the coordinator of the whole EPOCA project, was out there in a shower of sleet preparing test samples.

When I looked up the fjord to the huge glaciers, there was some floating ice to be seen in the distance. The mesocosms will be placed at the other,more sheltered end, but the one thing that could cause a problem, the scientists have told me, is if the wind changes and blows the icebergs down this way. The frames for the mesocosms are very stable, but the ice could damage the plastic sacks.I\’m told there will be some kind of barrier put round to protect them, still this is the main factor causing a little apprehension as the actual deployment comes closer. The team would like to start the experiment as soon as possible, but logistics have pushed the deployment back a little, probably to start tomorrow.

The world\’s most northerly post office (open once a week I believe!) looks picturesque even in a shower of sleet.
Meanwhile, the sun has been putting in the odd appearance, although it still keeps snowing or sleeeting, which gives a lovely light to the place. I think so anyway. The place is very quiet so far, probably a mixture of Sunday and the weather. Seems a shame to me not to be out and about.
Our resident Svalbard reindeer seems to think the same. Here he’s heading across the snow:

And as the summer comes in, he’s finding more and more tasty greenery:

Ny Alesund is a very unique kind of place. On the one hand, at 79° north, it’s a really remote location. At the same time, thanks to all the scientific interest, the small village is very well equipped to provide accommodation for a small group of privileged scientists who get permission to work here for some time during “their” research season. It’s a radio-silent area to avoid disturbing sensitive measuring equipment. Imagine a place with no mobile phones!
In winter, there are only a maximum of 30 people here, including the logistics staff. I’ve just been talking to Marcus Schumacher, who was the station leader until recently and is now the coordinator of the EPOCA research project on ocean acidification. He says there’s a great community feeling, just a few people in the long, winter months. Then, in March and April the glaciologists come in, when the snow is firm enough to get to the glaciers on snowmobiles. They’ve gone now, and the others are coming in, biologists, geologists, etc.
The village is a collection of different coloured buildings, occupied by a very international set of people. The Norwegians, obviously, have a station.

The French and Germans have a combined AWIPEV station.The Chinese have a station, so do the Koreans. 4 Indian scientists have just arrived at their station.

I dropped in there this morning and had a coffee chat with some of the team. More about their work at a later stage when I’ve interviewed them on their work. I was also made welcome by the head of the Norwegian station, who is actually German. (Science is very international). Again more later on the interesting things I discussed with him. The problem with being here is there are so many interesting things going on it’s hard to decide what to write when and to make sure you don’t miss anything while you’re writing – especially since it never gets dark and there’s no clear end to the “working day” for anybody. The sun has come out today for the first time since I’ve been here, so the urge to get out and take photos while the light is good is very strong.

At the moment there’s a special buzz about the place, with the team of scientists and technicians just arrived for the EPOCA ocean acidification project. At the same time, the Greenpeace ship came in with the mesocosms and loads of other equipment supplies for the project. Marcus is coordinating all this – must be quite a challenge. All of a sudden, this small, exclusive research station has trebled its population or something like that. It also means more people sharing the laboratory space and other equipment. Sandra Heinrich, a German PhD student who’s working here on macroalgae in the fjord showed me round the marine lab today.

This is her 4th time here, and she says it’s an ideal place to work. She really feels the difference since the arrival of all the extra people.
Another interesting thing is the cooperation between science and Greenpeace. This cooperation between the ngo best known for its spectacular protests and campaigns and an established scientific research organisation is a premiere. There was a lot of discussion beforehand on whether it was a good idea. The project was having problems finding a suitable boat, because they need the equipment to be up here for 5 weeks. Greenpeace stepped in with an offer to transport the mesocosms on the Esperanza, as they were planning an Arctic expedition anyway. It all seems to be working very well, in spite of some sensitivities. I know some of the scientists are wary of being associated with a campaign group, because they don’t want to compromise their scientific neutrality or be seen to be taking sides. At the same time the issue of ocean acidification is one that’s based on chemistry and facts, so not a controversial topic like climate change.
The Greenpeace team are doing a great job, very professional and keen to facilitate the scientific research in every way possible.

Another interesting relationship has been between some of the Norwegian seamen whose boat has been brought in to assist with some of the work. Given the country’s policy on whaling, it’s not surprising that the occasional tension has been felt. So far though, scientists, whale and seal hunters and the Greenpeace team are working well together in the interests of science and, I’m convinced, for the good of the planet.


View from my porthole.

The mesocosms are impressive pieces of equipment. It’s only when you see them up close and with people beside them that you realise how big they are and what a logistical challenge it is to get them up here to the Arctic and deployed in the Kongsfjord.

Professor Ulf Riebesell has been explaining to me exactly how they work.

He arrived two days ago and it’s “all systems go“, now that the season has started and the fjord is more or less ice free – at least at the point chosen here. There are nine separate “tubes“, which will be lowered from the Esperanza once everything is ready, each to contain their own little mini-cosmos of ocean life. The ocean absorbs around 30% of the CO2 we emit – good to buffer climate change, says Ulf, but bad for the creatures in the ocean that rely on calcium to form their shells or skeletons.
Co2 reacts with water and forms carbonic acid which makes oceans slowly more acidic. Lab experiments show that some organisms have a hard time, especially calcifying organisms, which need calcium to form their shells and skeletons.
On a global scale, this has implications for example for coral reefs, with their huge biodiversity, importance for coastal protection, the food supply and also for tourism. Calcifying organisms are everywhere, Ulf stresses, many organisms in ocean depend on forming calcium carbonate and are crucial links in the food webs. Scientists here will be looking particularly at a type of snail,the pteropod up to 1 cm in length, which, as our Professor puts it, have transformed their feet into wings. They’re also knows as butterflies of the sea.
They’re a key link in the food web between algae and higher trophic forms like whales etc. But they form their shells from material very susceptible to acidification. The scientists want to see what happens if they are affected by acidification, and what that would mean for the food web.
The Greenpeace boat has also transported loads of equipment the scientists will need to collect and test the samples in the Ny Alesund marine lab.

The Arctic, says Ulf, is the place to be to study ocean acidification. Cold waters take up more gas than warm. The polar oceans are close to the stage where water becomes corrosive for organisms depending on calcification. In 20-30 years some parts of Arctic will be completely corrosive for many organisms. Now that’s a scary thought.
And while there’s a lot of debate going on about what extent of climate change will have what effect – with ocean acidification, there’s no debate, Ulf says. It’s a chemical process and it’s easy to model how acidification will increase with certain levels of CO2 emissions. The big unknown is how it will affect marine life. And that’s the point of the giant test-tubes in this Arctic fjord. Unlike a lab experiment, which will look at individual organisms, the scientists here are looking at whole communities of life-forms. A daunting task – with potentially devastating results. We need to do something to reduce the CO2 emissions very, very soon, says the Kiel professor.
