Thanks to a partnership between the Canadian Space Agency (CSA), MacDonald, Dettwiler and Associates Ltd. (MDA), the prime contractor for the RADARSAT-2 program, and the Canadian Cryospheric Information Network (CCIN) at UWaterloo, the mosaic is free and fully accessible to the academic world and the public.

Using Synthetic Aperture Radar with multiple polarization modes aboard the RADARSAT-2 satellite, the CSA collected more than 3,150 images of the continent in the autumn of 2008, comprising a single pole-to-coast map covering all of Antarctica. This is the first such map of the area since RADARSAT-1 created one in 1997.
“The mosaic provides an update on the ever-changing ice cover in this area that will be of great interest to climatologists, geologists, biologists and oceanographers,” said Professor Ellsworth LeDrew, director of the CCIN and a professor in the Faculty of Environment at Waterloo.
“When compared to the previous Antarctic RADARSAT-1 mosaic, we can map changes in the icescape with unprecedented accuracy and confidence. The earth’s polar regions are considered a bellwether for the effects of climate change.”
Professor LeDrew is at the forefront of a cultural shift in the way researchers discover, share and preserve their research data. The CCIN links international researchers around the world with numerous government, university and private organizations to provide data and information management infrastructure for the Canadian cryospheric community. This mosaic map of the Antarctic is the latest addition to the CCIN’s Polar Data Catalogue. It is available on the Polar Data Catalogue website.
“The Polar Data Catalogue’s mandate is to make such information freely available to scientists, students and the public to enhance our understanding and stewardship of the polar regions,” said Professor LeDrew. “We are proud to work with the Canadian Space Agency and MDA to bring this outstanding Canadian technology and science to the international community.”
Next up for the partnership is a similar mosaic for Greenland, which will provide further crucial information about our shifting climate in the northern hemisphere. There are also plans to continue creating mosaics of Antarctica every few years to provide more data for researchers.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
