Sailing yacht TARA on new mission in the Mediterranean

May 29, 2014

Written by Zuzana Bednarova

Following more than four years of sailing around the world and the Arctic, sailing yacht Tara has set sail for a new mission in the popular Mediterranean yacht charter destinations, which will last until November 2014. The objectives of this mission are to accomplish scientific study concerning plastic pollution, and to promote awareness of environmental challenges in the Mediterranean region.

450 million people live along the Mediterranean coasts in 22 bordering countries. Due to its geography and climate, the Mediterranean Sea hosts close to 8% of global marine biodiversity, although representing only 0.8% of the ocean’s surface.

Today’s cities are saturated and almost 30% of the world’s maritime traffic is concentrated in the Mediterranean. Problems related to pollution from land are increasing, putting pressure on the marine ecosystem essential for the people of the region, and for life in general. Among the pollutants is the growing presence of micro-plastics.

These are most likely incorporated into the food chain, and thus into our diets. It is therefore urgent to find concrete solutions such as water treatment, waste management, biodegradable plastics, promotion of sustainable tourism, and the creation of Marine Protected Areas (MPAs) – solutions proposed decades ago by the Barcelona Convention, the U.N. Convention on Biological Diversity, and also by the European Union.

A scientific study on plastic will be conducted aboard expedition yacht Tara coordinated by the Laboratoire de Villefranchesur-mer (Université Pierre et Marie Curie and CNRS) and the University of Michigan (USA).

The accumulation of plastic debris in nature is “one of the most ubiquitous and long-lasting recent changes to the surface of our planet…” (Barnes et al, 2009), and one of the major environmental concerns of our time. Yet we know too little about what happens to these plastics and their role in ecosystem dynamics to predict their future impacts on the oceans of our planet and on humans.

To fill this gap, scientists board Tara yacht will undertake an interdisciplinary mission to better understand the impacts of plastic on the Mediterranean ecosystem. They will quantify plastic fragments, and measure their size and weight. They will also identify the types of plastic (and adhering organic pollutants) found in the sea, and study the dynamics and function of microbial communities (bacteria, protozans, micro-algae, molluscs, crustaceans) living on the plastic. Included in the latter are questions about the probable entry of these molecules into the food chain – a subject virtually unexplored in the Mediterranean. This floating plastic carted by large rivers flowing into the Mediterranean became a component of the ecosystem that influences the chemistry of the sea,” says Dr. Gaby Gorsky, chief scientist of the mission and director of the Oceanographic Observatory of Villefranche-sur-Mer.

This work will complement the research accomplished aboard Tara yacht in the Pacific during the Tara Oceans expedition in October 2011, and in the Arctic in 2013, and will add to the research carried out by the MED Expeditionin the north-western Mediterranean.

The results of this scientific study aim to influence the policy-makers and populations of countries bordering the Mediterranean towards better waste management and sanitation. The results will also encourage industrial innovation in developing new bio-degradable plastics.

Two scientists in charge of research protocols will always be on board, guided by satellite data via ground stations. Net hauls will be performed at the water’s surface, night and day, when sailing yacht Tara is at sea.

SCIENTIFIC GOALS OF THE TARA MEDITERRANEAN EXPEDITION:
– Evaluate the spatial distribution of floating plastic fragments (0.3 to 50 mm) in the Mediterranean Sea
– Chemical analyses of the different plastics
– Scanning electron microscopy, stereo microscopy and genomic analysis of microbial communities attached to the plastic
– Study the plankton ecosystems in contact with plastic fragments – day and night variability
– Record environmental characteristics – temperature, salinity, turbidity, pigments, ocean color

The team from the University of Maine (USA) in collaboration with NASA will also install instruments aboard superyacht Tara to measure turbidity in relation with algal pigments and satellite measurements.

SCIENTIFIC DIRECTOR:
Gaby Gorsky, Professor at UPMC, director of the Oceanographic Observatory of Villefranche sur mer (Université Pierre et Marie Curie and CNRS)
