PlanetSolar begins her hunt for ocean eddies in the North Atlantic

After several days of waiting for favorable weather, the MS Tûranor Planet Solar, the largest solar boat in the world, left the city of Boston, carrying 3 scientific team members from the University of Geneva (UNIGE), and a researcher from the Woods Hole Oceanographic Institution, the largest center of its kind in the world, with whom UNIGE is collaborating for this expedition. This important stopover in the capital of Massachusetts was crucial in the planning of the “DeepWater” expedition’s itinerary, which had initially planned for a stop in Iceland, a transatlantic crossing in the direction of Norway, coming to a close in Paris.After many discussions, hesitations and negotiations, the scientific committee—headed by Professor Martin Beniston and PlanetSolar’s captain Gérard d’Aboville—made the strategic decision to adjust the “DeepWater” expedition’s itinerary. The boat will not sail to Iceland; the measurement campaign will concentrate on the ocean eddies located between Boston and St. John’s (Canada). An additional stopover has therefore been added before St. John’s: Halifax (Canada). “Although the days are still long around Iceland in mid-August, the low angle of the sun relative to the boat’s photovoltaic panels would compromise the optimal acquisition of solar radiation. These sunlight conditions and the bleak weather forecasts for the rest of the summer prevented us from being able to guarantee a precise arrival date, which poses a number of logistical problems with regard to the scientific team members’ rotation” says Gérard d’Aboville.The MS Tûranor left the Mediterranean about three weeks later than planned. The

weather conditions were extremely poor this past spring, delaying the boat’s departure from the shipyard where she had been docked for major maintenance and optimizations. “The new navigation plan will enable us to concentrate more on the region of ocean eddies—large vortices that break off from the main part of the Gulf Stream. These phenomena influence heat exchanges with the atmosphere as well as the growth of phytoplankton where the powerful current leaves the east coast of the United States” says Professor Martin Beniston. “This new itinerary is an opportunity for our research. In fact, our route will follow a series of zigzags that enter and exit the Gulf Stream while intercepting several ocean eddies. This is the area where we expect to find the most interesting scientific results” he says. The solar catamaran is leaving Boston today, a stopover that was given a positive assessment by PlanetSolar and UNIGE thanks to the involvement of the public and of important institutions such as the Boston Children’s Museum, the Boston Science Museum, the MIT Energy Club, and the Woods Hole Oceanographic Institution..The “PlanetSolar DeepWater” Scientific Expedition Launched in Florida in early June, the “PlanetSolar DeepWater” expedition will strive to collect a continuous series of physical and biological measurements along the Gulf Stream, both in the water and in the air, using advanced instruments and the expertise of the UNIGE scientists. Led by Professor Martin Beniston, climatologist and director of the Institute of Environmental Science at UNIGE, the research team will study the key parameters of climate regulation, namely aerosols and phytoplankton, in order to better understand the complex interactions between the ocean and the atmosphere, as well as the role these interactions play in climate change.About PlanetSolar: The MS Tûranor PlanetSolar, built in Kiel, Germany, is a catamaran powered exclusively by solar energy. On May 4, 2012, after sailing for 584 days, the MS Tûranor PlanetSolar completed the first solar-powered

trip around the world. For her 2013 expeditions, the ship underwent major maintenance operations. The most significant optimization was related to the propulsion system—the surface propellers were replaced by a completely immerged system. In addition, the MS Tûranor PlanetSolar crew is comprised of: Gérard d’Aboville (Captain), Andrew Mikkelsen (Second), Antoine Simon (electrical engineer), Hugo Buratti (seaman and steward), and Vincent Brunet (steward). During the “PlanetSolar DeepWater” expedition, the UNIGE scientific team will round out the crew.After leaving Las Palmas (Spain) on April 26, 2013, the catamaran reached St. Martin (French West Indies) 22 days later. A new feat for PlanetSolar, who broke her own world record speed for a solar-powered transatlantic crossing, set in 26 days during her trip around the world. In order to fund the 2013 campaign, PlanetSolar SA is supported by the University of Geneva, Ciel électricité, Switcher, the Swiss AOC-IGP Association, Younicos, Plantbacter, Actides, GoPro, Jean-René Germanier SA, BCCC Attorneys-at-Law, Tempur, Hempel, Présence Suisse, Energissima, l’UIM, YELLO, and Waste Free Oceans. About the University of Geneva: Founded in 1559 by Jean Calvin and Théodore de Bèze, the University of Geneva (UNIGE) is now the second largest “Haute École” in Switzerland, and ranks among the top 100 universities in the world. Crown jewel of the Calvin community, the institution enjoys a privileged international reputation and cultivates its openness to the world. UNIGE welcomes approximately 16,000 students each year to its eight colleges, dealing with the essential domains of science, medicine, literature, economic and social sciences, law, theology, psychology, education, translation, and interpretation sciences. UNIGE has three missions: education, research, and service to the community. Additionally, UNIGE has been a member of the League of European Research Universities (LERU) since 2002. The University of Geneva would like to thank the Wright Foundation, the Henri Moser Foundation, and a generous anonymous donor for their support for the PlanetSolar DeepWater scientific campaign. —-– News from: PlanetSolar —– http://goodnews.ws/
