Impact of rheology on probabilistic forecasts of sea ice trajectories: application for search and rescue operations in the Arctic [PDF]

open access: yesThe Cryosphere, 2018
We present a sensitivity analysis and discuss the probabilistic forecast capabilities of the novel sea ice model neXtSIM used in hindcast mode. The study pertains to the response of the model to the uncertainty on winds using probabilistic forecasts ...

Operational SAR-based sea ice drift monitoring over the Baltic Sea [PDF]

open access: yesOcean Science, 2012
An algorithm for computing ice drift from pairs of synthetic aperture radar (SAR) images covering a common area has been developed at FMI. The algorithm has been developed based on the C-band SAR data over the Baltic Sea. It is based on phase correlation

Impact of Sea Ice Drift Retrieval Errors, Discretization and Grid Type on Calculations of Ice Deformation [PDF]

open access: yesRemote Sensing, 2018
We studied two issues to be considered in the calculation of parameters characterizing sea ice deformation: the effect of uncertainties in an automatically retrieved sea ice drift field, and the influence of the type of drift vector grid.

Multiscale variations in Arctic sea ice motion and links to atmospheric and oceanic conditions [PDF]

open access: yesThe Cryosphere, 2021
Arctic sea ice drift motion affects the global material balance, energy exchange and climate change and seriously affects the navigational safety of ships along certain channels.

Validating satellite derived and modelled sea-ice drift in the Laptev Sea with in situ measurements from the winter of 2007/2008 [PDF]

open access: yesPolar Research, 2011
A correct representation of the ice movement in an Arctic sea-ice–ocean coupled model is essential for a realistic sea-ice and ocean simulation. The aim of this study is to validate the observational and simulated sea-ice drift for the Laptev Sea ...

Atmospheric drivers of a winter-to-spring Lagrangian sea-ice drift in the Eastern Antarctic marginal ice zone

open access: yesJournal of Glaciology, 2022
Sea-ice drift in the Antarctic marginal ice zone (MIZ) is discussed using data from a 4-month-long drift of a buoy deployed on a pancake ice floe during the winter sea-ice expansion.

Towards a swath-to-swath sea-ice drift product for the Copernicus Imaging Microwave Radiometer mission [PDF]

open access: yesThe Cryosphere, 2021
Across spatial and temporal scales, sea-ice motion has implications for ship navigation, the sea-ice thickness distribution, sea-ice export to lower latitudes and re-circulation in the polar seas, among others.

Relationships between Arctic sea ice drift and strength modelled by NEMO-LIM3.6 [PDF]

open access: yesThe Cryosphere, 2017
Sea ice cover and thickness have substantially decreased in the Arctic Ocean since the beginning of the satellite era. As a result, sea ice strength has been reduced, allowing more deformation and fracturing and leading to increased sea ice drift ...

Instantaneous sea ice drift speed from TanDEM-X interferometry [PDF]

open access: yesThe Cryosphere, 2019
The drift of sea ice is an important geophysical process with widespread implications for the ocean energy budget and ecosystems. Drifting sea ice can also threaten marine operations and present a hazard for ocean vessels and installations.

Sea Ice Drift from GPS Tracker Deployed in the Arctic Ocean [PDF]

open access: yesGeo Data, 2023
Sea ice is monitored on a regular basis by satellite observation; however, image-based drift tracking is imprecise as the time interval forming the image-pair is too large to capture the actual trajectory of ice drift. In this study, drift trajectory and
