We are glad to inform the CryoSat scientific community that the reprocessed CryoSat Ocean Baseline C data for all of 2012 has been published on the Science Server and is available for download.

Following the successful CryoSat Quality Working Group Meeting held from 26 to 28 November 2018, the upcoming CryoSat Ice Baseline-D data products have been further refined.

The Baseline-D ice chain will be transferred to operation on 27 May 2019 and will include several evolutions as well as a new data format (NetCDF).

By combining 25 years of ESA satellite data, scientists have discovered that warming ocean waters have caused the ice to thin so rapidly that 24% of the glacier ice in West Antarctica is now affected.

Unfortunately ice is a hot topic when it comes to understanding and monitoring how this fragile component of the Earth system is being affected by climate change. Scientists, therefore, go to great lengths to study changes happening in the remote icy reaches of our planet – a subject that is being discussed in detail at this week's Living Planet Symposium in Italy.

Using a 25-year record of ESA satellite data, recent research shows that the pace at which Greenland is losing ice is getting faster.

In a major collaborative effort, scientists from around the world have used information from satellites to reveal that ice melting in Antarctica has not only raised sea levels by 7.6 mm since 1992, but, critically, almost half of this rise has occurred in the last five years.

Thanks to ESA's CryoSat mission, a new map of Antarctica provides the most accurate 3D view ever of the continent's vast ice sheet and floating ice shelves.

While ESA's CryoSat continues to provide clear insight into how much sea ice is being lost and how the Antarctic and Greenlandic ice sheets are changing, the mission has again surpassed its original scope by revealing exactly how mountain glaciers are also succumbing to change.

ESA's CryoSat mission has revealed that, over the last seven years, Antarctica has lost an area of underwater ice the size of Greater London. This is because warm ocean water beneath the continent's floating margins is eating away at the ice attached to the seabed.

We are all aware that Antarctica's ice shelves are thinning, but recently scientists have also discovered huge canyons cutting through the underbelly of these shelves, potentially making them even more fragile. Thanks to the CryoSat and Sentinel-1 missions, new light is being shed on this hidden world.

All eyes are on Antarctica's Larsen C ice shelf as a deep crack continues to cut across the ice, leaving a huge chunk clinging on.

Science

Almost 80% of the Earth's fresh water is locked up in the cryosphere, i.e. snow, ice and permafrost. The cryosphere plays an important role in moderating the global climate and as such, the consequences of receding ice cover due to global warming are far reaching and complex. Due to its high albedo, ice masses directly affect the global energy budget by reflecting about 80% of incident sunlight back out to space.
