Vendee Globe route seen from above

15.12.2008
Wind and wave data from ESA’s Envisat satellite radar are being used to observe meteorological conditions in the track of the Vendee Globe solo round-the-world yacht race.

CLS, a subsidiary of the French Space Agency (CNES), acting through its new radar applications division (formerly the BOOST Technologies Company), is using the race to demonstrate the ability of Envisat radar imagery to operationally observe oceans at high resolution.

Based on the trajectory and speed of the boats, CLS is acquiring data over the area skippers will be sailing into slightly ahead of their arrival time in order to monitor the metocean conditions.

Although skippers are forbidden to receive outside assistance in the Vendee Globe race, these data will be helpful for skippers planning optimal routes in races where new types of meteorological information will be allowed.

"These innovative techniques providing wind and wave information at unprecedented resolution will certainly be directly transmitted to sailors in other races in the future to help them determine the most appropriate route in challenging regions of fast-changing metocean conditions such as the Canary Islands or the Saint Helene high pressure system," said Dr Fabrice Collard of France's CLS radar application division in Brest.

These wind and wave product demonstrations, originally tested over Europe, are part of an ESA research project on innovative retrieval techniques. The development and processing techniques are being extended to Envisat Advanced Synthetic Aperture Radar (ASAR) data acquired along the Vendee Globe route.

The Vendee Globe takes sailors through severe wind and wave conditions in the Southern Ocean, which is also home to many icebergs. The data used in this test was originally acquired for the purpose of iceberg detection.

The long swells and high winds typical of the Southern Ocean have been clearly identified with a high-resolution variability that may provide new insight for the understanding of complex and remote seas.

As part of the Global Monitoring for Environment and Security (GMES), a joint initiative of the European Commission and ESA, ESA has undertaken the development of Sentinel-1 for the continuation of SAR operational applications.

Dr Vincent Kerbaol, head of the radar application division of CLS said: "This ESA and CLS research demonstration using Envisat data provides an excellent taste of the wind and wave products that will be delivered operationally to the GMES services using the next generation SAR onboard ESA’s Sentinel-1 satellite to enhance the maritime safety and awareness."

CLS will hold a press conference on 16 December 2008 at the Vendee Globe headquarters in Paris where they will present the principles of iceberg detection using Envisat ASAR data. By invitation from CLS, ESA and CNES will participate in the conference.

Im Focus: Solving the mystery of quantum light in thin layers

A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna)

It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to...

Im Focus: An ultrafast glimpse of the photochemistry of the atmosphere

Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols.

The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between radiation and matter. Light strikes particles...

Im Focus: Shaping nanoparticles for improved quantum information technology

Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.

Researchers at the Center for Nanoscale Materials (CNM), a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Argonne National...

Im Focus: Novel Material for Shipbuilding

A new research project at the TH Mittelhessen focusses on the development of a novel light weight design concept for leisure boats and yachts. Professor Stephan Marzi from the THM Institute of Mechanics and Materials collaborates with Krake Catamarane, which is a shipyard located in Apolda, Thuringia.

The project is set up in an international cooperation with Professor Anders Biel from Karlstad University in Sweden and the Swedish company Lamera from...

Im Focus: Controlling superconducting regions within an exotic metal

Superconductivity has fascinated scientists for many years since it offers the potential to revolutionize current technologies. Materials only become superconductors - meaning that electrons can travel in them with no resistance - at very low temperatures. These days, this unique zero resistance superconductivity is commonly found in a number of technologies, such as magnetic resonance imaging (MRI).

Future technologies, however, will harness the total synchrony of electronic behavior in superconductors - a property called the phase. There is currently a...
