Geographic muting of changes in the Arctic sea ice cover [PDF]
, 2010 The seasonal cycle in Arctic sea ice extent is asymmetric. Its amplitude has grown in recent decades as the ice has retreated more rapidly in summer than in winter.

Sensors, 2019 Observing sea ice by very high-resolution (VHR) images not only improves the quality of lower-resolution remote sensing products (e.g., sea ice concentration, distribution of melt ponds and pressure ridges, sea ice surface roughness, etc.) by providing ...

New insight into the influence of the Greenland high on summer Arctic sea ice
Environmental Research Letters, 2022 The Greenland high (GL-high) coincides with a local center of action of the summer North Atlantic Oscillation and is known to have significant influence on Greenland ice sheet melting and summer Arctic sea ice. However, the mechanism behind the influence

Classification of sea ice types in Sentinel-1 synthetic aperture radar images [PDF]
The Cryosphere, 2020 A new Sentinel-1 image-based sea ice classification algorithm using a machine-learning-based model trained in a semi-automated manner is proposed to support daily ice charting.

ASTER-Derived High-Resolution Ice Surface Temperature for the Arctic Coast
Remote Sensing, 2018 Ice surface temperature (IST) controls the rate of sea ice growth and the heat exchange between the atmosphere and ocean. In this study, high-resolution IST using the Advanced Spaceborne Thermal Emission and Reflection radiometer (ASTER) thermal infrared

Arctic oscillation and Arctic sea‐ice oscillation [PDF]
Geophysical Research Letters, 2000 The variability of the sea‐ice cover in the Arctic and subpolar regions associated with the Arctic Oscillation (AO) was investigated using historical data from 1901 to 1997. Unrotating principal component analyses (or empirical orthogonal functions, EOFs) were applied to demeaned, normalized sea‐level pressure (SLP), surface air temperature (SAT), and ...

The impact of a seasonally ice free Arctic Ocean on the temperature, precipitation and surface mass balance of Svalbard [PDF]
, 2012 The observed decline in summer sea ice extent since the 1970s is predicted to continue until the Arctic Ocean is seasonally ice free during the 21st Century. This will lead to a much perturbed Arctic climate with large changes in ocean surface energy flux.

, 2012 The Arctic is currently undergoing rapid environmental changes (ACIA, 2005; IPCC, 2007). One of the most striking of these changes is the decline in the floating sea ice cover. Sea ice is frozen sea water that forms in winter as temperatures drop and darkness sets over the northern high latitudes.

Predicting September sea ice: Ensemble skill of the SEARCH Sea Ice Outlook 2008-2013 [PDF]
, 2014 Since 2008, the Study of Environmental Arctic Change Sea Ice Outlook has solicited predictions of September sea-ice extent from the Arctic research community.

Prediction of Arctic Sea Ice Concentration Using a Fully Data Driven Deep Neural Network
Remote Sensing, 2017 The Arctic sea ice is an important indicator of the progress of global warming and climate change. Prediction of Arctic sea ice concentration has been investigated by many disciplines and predictions have been made using a variety of methods.
