Snow and Ice
One tenth of the Earth's surface is permanently covered in ice, but snow and ice is present across the world in varying amounts during the seasons. This process of ice forming and melting is an important indication of climate change, and satellites play a vital role in tracking this.
Satellite observations can also help to track glaciers and icebergs, and help plot safe shipping routes through icy conditions.

While two explorers were having problems cruising the ice across the North Pole on skies, due to bad weather and complications with equipment, the Copernicus Sentinel-1 satellites lent a hand to guide rescuers through the maze of ice and water to save the day.
Over the last few months, a chunk of Antarctica's Larsen C ice shelf has been hanging on precariously as a deep crack cut across the ice. Witnessed by the Copernicus Sentinel-1 mission, a lump of ice more than twice the size of Luxembourg has now broken off, spawning one of the largest icebergs on record and changing the outline of the Antarctic Peninsula forever.

Sea ice is a rapidly changing phenomenon. Timely measurements over large areas, at high spatial and temporal resolutions, are fundamental for its surveillance.

One of Greenland's glaciers is losing five billion tonnes of ice a year to the ocean, according to researchers. While these new findings may be disturbing, they are reinforced by a concerted effort to map changes in ice sheets with different sensors from space agencies around the world.

With the new Earth observation satellites carrying a range of technologies such as radar and multispectral imaging instruments for land, ocean and atmospheric monitoring, data are available for the next 20-30 years. However, this means little unless there are capable people handling them.

From climate change monitoring to supporting humanitarian aid and crisis situations, early data applications from the month-old Sentinel-1A satellite show how the radar mission's critical observations can be used to keep us and our planet safe.

Daugaard Jensen Gletscher, Greenland, is a large tidewater glacier covering an estimated 4% of the Greenland ice sheet. In this study the team investigate whether recent changes in the dynamics and mass balance of this sector of the Greenland ice sheet are reflected in the behaviour of this particular glacier.

After two decades of satellite observations, an international team of experts brought together by ESA and NASA has produced the most accurate assessment of ice losses from Antarctica and Greenland to date. This study finds that the combined rate of ice sheet melting is increasing.
