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: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
