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, …
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 …
Accurate estimates of sea ice thickness are essential for numerical weather prediction, ice extent forecasts for navigability and to demonstrate the impacts of climate change on sea ice. The main source of uncertainty in sea ice thickness measurements from radar altimetry is due to snow. Scattering of the radar signal as it travels through snow …
Using CryoSat-2 interferometric synthetic aperture radar (SARIn) altimetry together with NASA’s operation IceBridge and IceSat-2 Lidar data in a multi-layer neural network (NN) in order to enhance CryoSat-2 SARIn swath measurements. Further investigation will be carried out into the use of these corrections to derive surface condition state and change. The European Space Agency (ESA), …
HYDROCOASTAL was a project aimed at maximising the exploitation of SAR and SARIn altimeter measurements in the coastal zone and inland waters, by evaluating and implementing new approaches to process data from CryoSat-2 and Sentinel-3. Optical data from Sentinel-2 MSI and Sentinel-3 OLCI instruments will also be used in generating River Discharge products. New SAR …
The CryoTEMPO-EOLIS (Elevation Over Land Ice from Swath) product, now operationally available at on the CryoSat Dissemination Server, exploits CryoSat’s SARIn mode and the novel Swath processing technique to deliver increased spatial and temporal coverage of time-dependent elevation over land ice, a critical metric for tracking ice mass trends. This is the outcome of a …
Ice sheets are a key component of the Earth system, impacting on global sea level, ocean circulation and bio-geochemical processes. Significant quantities of liquid water are being produced and transported at the ice sheet surface, base, and beneath its floating sections, and this water is in turn interacting with the ice sheet itself. Surface meltwater …
Living Planet Fellowship research project carried out by Jack Landy. Arctic-SummIT will deliver, for the first time, a sea ice thickness product during summer months from the ESA Cryosat-2 satellite. As the extent of Arctic sea ice has declined at unprecedented speed over the past few decades, we have been able to view only limited …
The aimof this activity is To exploit the synergy between Sentinel instruments and other mission EO datasets together with in situ measurements in complex waters and improve scientific understanding of ocean and coastal processes and impacts.The main objective of the project is to develop a virtual plateform to allow oceanographers to discover the existence and …
