Naiara Berrojalbiz: "The goal is to analyze climate change at the poles"

Traveling to the Arctic is a stimulating experience for anyone, more for a researcher, since these types of options are very scarce. Duranguesa Naiara Berrojalbiz took full advantage of this opportunity. He is doing a doctoral thesis at the Institute of Chemistry and Environmental Research of the CSIC of Barcelona. In summer, the ship BIO Hesperides participated in a campaign in the Arctic, and is now just around a campaign in the Antarctic. A few weeks ago he spent a few days at home and we chatted with him about the previous trip: To the Arctic BIO Hesperides in.

How is BIO Hesperides? It has been described as a floating laboratory.

And so it is. In fact, the boat itself and its crew are also military, but its main objective is the one dedicated to science. An important part is the laboratories, which have measuring instruments and, above all, oceanographic measuring devices.

Let's talk about your project: Project Atos.

Last year, 2007-2008, was the fourth international polar year, in which numerous polar research projects emerged. The Atos project follows this philosophy. In our case, we seek information on climate change to combat it. Therefore, the goal is to analyze what climate change is at the poles.

For this, two campaigns: one in the Arctic and one in the Antarctic. You have already joined, you have been in the Arctic. Is there any reason to start?

It is above all a question of logistics and calendar of the ship itself. In fact, this campaign, that of Antarctica, was planned for last year, within the international polar year, but due to logistical problems, we will do it this year. In both cases the project is the same and the objectives are the same.

How do you remember your trip to the Arctic?

We took the boat in Iceland, in Reykjavik. We made our tour and left us in the Svalbardas. In the sea we were only thirty days - in Antarctica we will be forty-two days - something shorter but of great intensity.

What was a day like in the Arctic?

Normally we started the day with a station, that is, the boat remained at a certain point. We started taking samples and measurements: fishing, taking plankton samples (phytoplankton, zooplankton...) and also taking water samples for analysis (inorganic and organic pollutants, primary productivity... a little bit of everything). It is a multidisciplinary team: biologists, chemists, physicists... And everyone analyzes their area. It's nice, because we work together and come up with nice ideas.

Sampling on trips to the Poles is one of the tasks of Naiara and her companions.

And once collected the samples?

Then, in our case, everything has to meet well to take it to Barcelona. We analyze persistent organic pollutants, called POPs. They require very clean conditions and very long processes for analysis and extraction of information. Therefore, we must collect very well the samples on the boat so as not to contaminate them on the way. Once assembled, we sent them to Barcelona, and so, once back to Barcelona, we have a work of months processing these samples.

Do you research right there?

Yes, we do degradation experiments and others right there, and we also work in collaboration with other groups. But the truth is that our main objective is the collection and collection of samples.

Working in that place, right?

Yes, the landscape is wonderful. Among other things, we saw seals, whales and a polar bear!

On their trip to the Arctic they were fortunate to see a polar bear closely.

He mentioned the polar bear, because contaminants enter the trophic chain, so they focus on animals located at the end of the chain. And the polar bear, for example, is very polluted.

Yes, polar bears have many contaminants that tend to bioaccumulate. And not only bears, but also inuit. Inuit children have had dysfunctions in some organs and have apparently told mothers not to breastfeed children, since the pollutants accumulated by the mother are expelled through milk.

It is surprising that the pollution generated by the cars here affects the poles.

And not only pollutants caused by combustion of engines, but also pesticides, and contaminants present in different substances of daily use. These pollutants pass into the air, many are persistent and, along with the air, reach the poles. Due to their temperature and pressure conditions, these contaminants accumulate, passing into water and storing in ice.

Therefore, we should take water samples, air samples, plankton and ice. The analysis of the samples involves analyzing the behavior of permanent contaminants when data is available. We pursue persistent organic compounds. They are characterized by being toxic to animals, bioaccumulative and durable to travel over long distances.

In addition to working, Naiara enjoyed the landscape and nature of the Arctic.

I'm curious, how is a boat's laboratory? The balance of the sea risks falling... Is the material glass?

Yes, yes, it is glass. But we already have a lot of experience and we put everything well tied, everything in place for nothing to spoil. However, in the Arctic we had a relaxed atmosphere.

In my case I have the fifth campaign at sea. Before, I have also visited the Mediterranean and the Atlantic, where it has touched the bad weather. In these cases, it is best to stop working.

Bio Hesperides binary
In the Arctic, 17 July 2008
(...) Anyway, don't think the game takes us away from our main goal -- for the reason it makes us get out of the bed of the group. Know that soño every night with filtration systems, insulating tape and permanent markers (all the tools necessary for a good laboratory). These thirty days are polluting and will be my reason for being. With Romá, Silvia and Cristóbal we formed the POP group of the boat. With this I do not mean that we give concerts on deck to set the luminous Arctic nights (although the musical option that is heard in our laboratory would enjoy the ear of the most demanding melodic).

Our main obligation is to know better the behavior and distribution of POPs in cold waters of the Arctic Ocean, Persistent Organic Pollutants, trying to determine their impact on this ecosystem so affected by climate change. Although these pollutants are generated by human activities (industry, agriculture, etc. ), due to their physical-chemical characteristics they are relatively persistent (difficult to degrade), durable enough so that the air masses can be driven thousands of kilometers from the source to distant places like the Arctic. In this way, the atmosphere is a source of POP that allows the passage to ocean waters, where they are stored in living organisms. This phenomenon produces an increase in harmful toxic effects both in the lower links (plankton) of the trophic chain and in the upper ones (seal, polar bear, man). In this way, to collect all the possible data about the presence of pollutants in the different media of the ecosystem (atmosphere, water and planktonic organisms), during the 30 days that this adventure will last, we will filter hundreds of cubic meters of air and how many liters of water, until filling the suitcases with filters, extracts, samples and kilos of statistics; we carry with us a work of months of analysis and processing (what I thought was wrong).
I just have to take advantage of the time left in BIO Hesperides, as we are in the final stretch of the campaign. So I think I'm going to leak, or watch a movie, or have a coffee, or all at once, if not.
