Estimating sea ice thickness is essential to monitor the effects of long-term climatic change and understand their consequences for Arctic ecosystems. The continued sea ice loss – widely observed through EO data since 1979 – is bringing to an increased Arctic maritime activity for which timely forecasts of ice conditions are required too, to ensure …
Develop and validate novel methods for Sea State retrieval from Sentinel-1 Interferometric Wide Swath (IWS) products. Produce experimental S-1 IWS Sea State products and demonstrate their value for coastal science, operational wave models, and selected test areas including the marginal ice zone in the Arctic. Demonstrate multi-mission EO synergies in the Mediterranean utilising ocean geophysical …
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 …
The Cryosphere Virtual Lab is a system that uses recent information and communication technologies to facilitate the exploitation analysis, sharing, mining and visualization of the massive amounts of earth observation data available on the cryosphere. The system utilises available satellite, in-situ and model data from ESA/EU, Svalbard Observatory (SIOS) and other sources. CVL fosters collaboration between …
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 European Space Agency (ESA) organised the 6th Advanced Course on Radar Polarimetry dedicated to training the next generation of Earth Observation (EO) scientists to exploit dual and fully polarimetric data for science and applications development. Due to the COVID-19 pandemic, the event took place in an online format. A total of 40 post-graduate, PhD …
