PlanetSolar drops anchor in St. John's, the northernmost point the solar vessel has ever reached

During the afternoon of August 1, the gigantic catamaran arrived in the city of St. John's (Canada). Leaving Halifax (Canada) on July 22, the ship and her crew are continuing on their “PlanetSolar DeepWater” scientific expedition, a measurement campaign conducted along the Gulf Stream.

This scientific adventure is a unique opportunity for researchers from the University of Geneva (UNIGE) to observe and analyze eddies. By reaching Newfoundland, a region known for its difficult navigational conditions and frequent fog, the MS Tûranor PlanetSolar demonstrated that solar navigation is possible even in the heart of areas with intermittent sunlight.

St. John's is the most northerly point the world's largest solar boat has ever reached. After leaving Halifax, the journey that separated the two Canadian cities enabled UNIGE scientists to pursue their research and analysis of the phenomenon of eddies—large vortices that break away from the main part of the Gulf Stream. They have an effect on heat exchanges with the atmosphere and phytoplankton growth. Between Boston and Halifax, the data collected showed a noticeable increase in the number of aerosols as the ship gradually moved closer to Canada.

This time, the UNIGE scientific team intercepted the vortices off the coast of Nova Scotia. "Although the data collected thus far is still in a very preliminary phase of analysis, the aerosol measurements seem to suggest that the quantity of microparticles suspended in the air, emitted by the ocean, is higher than anticipated. The truth is, our knowledge about oceanic aerosols is very incomplete, and the measurements taken by the "Biobox" (developed by the Applied Physics Groups at the University of Geneva) could deliver completely unprecedented results and thereby shed new light on oceanic influence on climate," says Professor Martin Beniston, climatologist and director of the Institute of Environmental Science at UNIGE.

“This trip, carried out in a zigzag, was tricky, and was a significant challenge in terms of solar navigation,” says Gérard d'Aboville, captain of the MS Tûranor PlanetSolar. “In fact, the Newfoundland region is known for its dense fog, because the cold Labrador Current meets the warm Gulf Stream Current there. In addition, a northeasterly wind slowed down our journey,” adds d'Aboville.

The stopover in St. John's will last until August 5, allowing the “PlanetSolar DeepWater” scientific teammates a rotation. The MS Tûranor PlanetSolar will then set off into the vastness of the North Atlantic, heading for the United Kingdom. Over 3'500 kilometers await the ship and her crew.

The “PlanetSolar DeepWater” scientific Expedition

Launched in Florida in early June, the “PlanetSolar DeepWater” expedition is striving 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 is studying 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), Brieuc Delbot (Second), Antoine Simon (electrical engineer), Hugo Buratti (seaman and steward), and Vincent Brunet (steward). During the “PlanetSolar DeepWater” expedition, the UNIGE scientific team is rounding out the crew.

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, 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.

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
