The Copernicus Earth-observation program delivers a steady stream of
information about how the planet changes from day to day.
Run by the European Commission and the European Space
Agency, Copernicus uses satellites called Sentinels that continuously monitor
Earth from space and tools on the ground for calibration and cross-checking.Continue reading International eye in the sky
Ninety-nine per cent of all tsunami-related deaths have occurred in the Asia-Pacific region, according to the United Nations Economic and Social Commission for Asia and the Pacific. Indonesian and Australian scientists have been working to reduce this figure—by creating artificial earthquakes and tsunamis.
Building off more than 15 years of research from Indonesian, Singaporean, American, and Australian scientists, the team created a collection of scenarios, for earthquakes of different magnitudes and the resulting tsunamis that would affect West Sumatra, Indonesia.

Researchers at Geoscience Australia have unravelled the development of a unique seafloor community thriving in complete darkness below the giant ice sheets of Antarctica.The community beneath the Amery Ice Shelf in Antarctica is 100 kilometres from open water and hidden from view by ice half a kilometre thick. This ecosystem has developed very slowly over the past 9,000 years, since the end of the last glaciation.
Today it is home to animals such as sponges and bryozoans fed by plankton carried in on the current. Dr Alix Post studied shell fossils within core samples where she unexpectedly found evidence of these isolated ecosystems.
