More of the end… disassembling the mesocosms (by Angela)

It’s been a week since the mesocosms were dismantled, each time three of them were pulled out of the sea and “attaked” by the Villefranche group. To see and help on this gave the opportunity to understand the magnitude of the logistic behind.

The engineers that concived the structure were at the harbour helping and taking care that everything was stored and treated properly for the next experiments. Every single tube had to be washed, packed and stored; ropes and buoys cleaned and with out air, plastics folded and packed for recycling. The divers had long days taking the things out of the water and the rest of the team with the afterwards. Some people took a bath inside the mesocosms while cutting the ropes, I am sure most of us wanted to do that. Now everything is packed and ready to use for the next experiment. Así que: buen viento y buena mar!

All right. The LOV team has completed its task of cleaning the Stareso harbor, disassembling the mesocosms and make clear the laboratories. Home sweet home!
But I will miss Stareso, Corsica and this mission for MedSeA Project ..
I will miss the sunrises and sunsets, spectacular landscapes, the madness with colleagues, Winkler party (!) and not just that, all works by night, the alarm set at 3.30 am for the process sampling, the different cultures and shared knowledges.

It was a wonderful experience for me (super!), where fatigue has begun to be felt at about half the work but not prevented us from achieving our set goals. Everything has been completed, almost everything went smoothly and I’m very happy.
Now we just have to work on the data obtained, as far as I’m concerned about the analysis of O2 and make some considerations .. but I am compelled to share the office of the Laboratory of Villefranche with this researcher …

Samir at home…

and after all..

I hope to see you all together soon!!


It was mentioned before that acidification is being done gradually, it was my turn to join one of those steps!. First Frederic saturated the big water tank up to a million ppm CO2. Then we filled the “little” 20 litter bottles and put them in the boat together with the “spider” that looked more like a fine shower, few things more …and ready!

It was a windy morning so the platforms were moving a bit, we placed all bottles on them and after a little struggling we managed to arrive to the mesocosms. We pumped 40 litters in one and 60 litters in another. We even got a few time to chill out while pumping ;)And on the way back: frijoles! beans! were waiting for us.


Preparing the labs and hungry eel

Most scientists have arrived to the Stareso station, plans have been discussed and our first general meeting was held. Everybody is installing the equipment, so the labs have change a lot from yesterday to today; from a messy mass of boxes, bottles, tubes, cables and pumps to proper laboratories.

However not everything was that easy: yesterday one of the mesocosms lost water and so, all of them needed to be open and acidified again. The divers needed to repair again!.  Since the acidification is gradual, this caused a delay of two days in our original plans.  And today, the day started with a hungry eel having a taste of finger for breakfast. But work won´t stop, we will have test samplings at 8pm in the next two days and hopefully Andy’s finger will have some extra time to heel before starting the experiment.

Some leave, other arrive

People from the preparation step gradually leave. David and Jean-Yves, who were here to do videos of the preparation as well as sub-marine sequences, left Tuesday. They were happy of the movies they have done on our work and the biodiversity around Stareso. Jean-Michel and Bruno (our jukebox) left this afternoon!!

They left… the mesocosms also!! Yesterday morning we had the bad surprise to see a new repartition between the 3 sets of mesocosms. After 4 intensive days of wind one of the line maintaining a set of mesocosms broke!! Since Saturday evening it blows a lot, we had a maximum wind of 50knots!! It was a good test for the anchor’s resistance but after 4 days of the line didn’t resist. The divers went quickly to repare.

The 3 sets should be aligned and not like a triangle…

So, before other participants arrive, between Saturday and Sunday, we still have preparation to finish the installation. Today we tested the three platforms to receive people when sampling. They consist in an assemblage of cubis and linked with the mesocosms by ropes. We also did a test if someone fall in water to go back on the platform… it’s not an easy job when alone with jellyfish around!! But we’ll never be alone on a platform, 3 people will be together for sampling 3 mesocosms.

Beautiful colors on the installation. At the bottom of the dock, the grey floating system is one of the platform we’ll use to take the samples.

The show must go on

It’s been a week now that the LOV team invaded the Stareso station. It took us several days to build the mesocosms and to anchor them in a site located feww hundred meters from the harbor. The divers did a very good job, the 9 mesocosms are now deployed and should be closed by tomorrow. Then we will fix the roofs and the pH regulation can start. We’ll explain in a post how we will acidify the mesocosms.

Concerning the labs, everything has been cleaned and we already installed all our material. Now, we wait for our colleagues to arrive to finish the installation !
