Danish expedition ship tracked by Envisat satellite

14.08.2006
The Danish ship Vædderen has embarked from Copenhagen on its science expedition trip, Galathea 3. As part of the ‘Satellite Eye for Galathea 3’ project, ESA’s Envisat satellite will acquire data along the ship’s sailing route throughout its eight-month voyage.

The purpose of the expedition is to carry out research on climate and weather changes, earthquakes, tsunamis and animal and plant marine life. The Satellite Eye project – coordinated by Risø National Laboratory and sponsored by ESA and Egmont Fonden – is mainly an educational project and ensures the delivery of daily Envisat satellite images of the ship’s route as well as other relevant locations along its track.

Daily observations of sea surface temperature, sea level height, chlorophyll and ocean colour, along with ocean wind mapping will be analysed onboard by a teacher-student team.

Scientists will be working with the teams to analyse the incoming satellite images and to produce easily understood educational reports for the public. Satellite images will also be acquired over each harbour Vædderen visits to show the development and changes of harbour towns.

Charlotte Hasager, Project Coordinator and senior scientist at Risø National Laboratory, said: "The project is already a success because some 15 projects onboard Galathea 3 are now planning to use the satellite images. Students will also learn about our planet through Earth Observation technology. Satellite images stimulate most people to ask questions about what we are seeing and how we are able to see it."

The satellite data will quantify the highly dynamical processes in the marine, atmospheric and coastal environment. Under the Satellite Eye project, the images will be loaded to a database in near-real-time and made available to schools and the scientific community via a satellite link to the ship. All educational material will be available to schools and the public through ESA’s Eduspace multi-language website and the Danish educational website. Images during the cruise will also be displayed in Google Earth.

The course takes the ship to the North Atlantic, with stops in the Faroe Islands and Greenland. The route will then turn south along the west coast of Africa to Cape Town before continuing to Australia and Antarctica, then north along the west coast of South America to the Galapagos Islands, through the Panama Canal, the Caribbean and New York. The expedition concludes its circumnavigation of the globe with a voyage across the Atlantic and will return to Copenhagen in April 2007.

The expedition is deeply rooted in history with the first Galathea Expedition, commissioned by King Christian VIII, dating back to 1845. The second Galathea Expedition occurred in 1950. Both were circumnavigations of the globe and yielded remarkable scientific results.

Galathea 3 marks the first time the expedition has been carried out since the development of Earth Observation from satellites. Visiting the same places as the previous expeditions, Galathea 3 is set to follow up on the research carried out by its predecessors. Several members of the Danish press are travelling onboard Vædderen to document the event, and a film and book are already in the planning.

The Vædderen ship belongs to the Danish navy and has undergone extensive rebuilding and modernisation to make it suitable and well-functioning for such an expedition. It has also been furnished with laboratories, advanced apparatus and other equipment necessary for the researchers to carry out their projects. The instruments onboard Vædderen will observe similar parameters as the satellite observations, in order to build a cross-referenced complementary archive of satellite and ground measurements and allow accurate calibration and validation exercises.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
