Ice velocity is an essential parameter to study ice sheet and glacier dynamics. It is needed to estimate the mass flux and discharge of ice from the accumulation zone to the ocean and hence influences estimates of ice sheet mass balance and sea level rise. Furthermore, ice velocity measurements constitute valuable input for constraining and …
Kicking-off next 1 July, a 15m€ project funded by the European Union is about to promote the integration of international environmental observing systems for the Arctic and improve the tailoring of these systems to the needs of various user groups – including local inhabitants, academia, industry and decision makers – for the 2021-2025 period.

The ALBATROSS Project (ALtimetry for BAthymetry and Tide Retrievals for the Southern Ocean, Sea ice and ice Shelves) , led by NOVELTIS in collaboration with DTU, NPI and UCL, is one of the activities funded by ESA in the frame of the Polar Science Cluster, with the objective to foster collaborative research and interdisciplinary networking …
Sea ice in key Arctic coastal regions is thinning at a rate of 70–100% faster than previously thought. These values, reported in a paper recently published in The Cryosphere, are derived when the sea ice thickness in the period 2002–2018 is calculated using new snow data with more realistic variability and trends. Results are outcomes …
Between 2010 and 2019, the Gulf of Alaska lost 76 Gt of ice per year while High Mountain Asia lost 28 Gt of ice per year. These losses are equivalent to adding 0.21 mm and 0.05 mm to sea level rise per year, respectively. The results, based on interferometric swath processing of CryoSat-2 altimeter data, …
The Glacier Science in the Alps project is part of the Alps Regional Initiative and is aimed at maximising the scientific return of European investments in EO specifically from Sentinel-1 and Sentinel-2 specifically to provide first enhanced observation capacity for glaciers in the Alps beyond area to glacier velocity and end of season snow cover …
A seminal article on the progress of satellite altimetry and its future has been published on-line in Advances in Space Research on 23 March 2021. It is authored by the International Altimetry Team, which is composed of more than 360 co-authors. In 2018, in Ponta Delgada, the Azores, Portugal, celebrations took place for 25 years …
How to take advantage of optical satellites with near-simultaneous acquisitions to monitor fast displacements that occur at or near the Earth’s surface over large scales? Replying to this question with respect to spring river ice break-up and associated ice-runs at Northern latitudes was the objective of a study by Living Planet fellow Bas Altena who …
Using a 25-year record of satellite observations over the Getz region in West Antarctica, scientists have discovered that the pace at which glaciers flow towards the ocean is accelerating. This new research, which includes data from the Copernicus Sentinel-1 mission and ESA’s CryoSat mission, will help determine if these glaciers could collapse in the next …
