Sea ice concentration impacts dissolved organic gases in the Canadian Arctic [PDF]
Biogeosciences, 2021 Abstract. The marginal sea ice zone has been identified as a source of different climate active gases to the atmosphere due to its unique biogeochemistry. However, it remains highly undersampled and the impact of changes in sea ice concentration on the distributions of these gases is poorly understood.

Assimilation of sea-ice concentration in a global climate model — physical and statistical aspects [PDF]
, 2012 We investigate the initialisation of Northern Hemisphere sea ice in the global climate model ECHAM5/MPI-OM by assimilating sea-ice concentration data. The analysis updates for concentration are given by Newtonian relaxation, and we discuss different ways

Relationship between sea ice concentration and sea ice albedo over Antarctica
Korean Journal of Remote Sensing, 2015 Abstract : Sea ice is a key parameter for understanding the climate change in cryosphere. In this study,we investigated the correlation with the factors that influenced change of the sea ice extent. We used the SeaIce Concentration (SIC) from Ocean and Sea Ice Satellite Application Facility (OSI-SAF), and surface albedoprovided by The Satellite ...

On sea ice concentration anomaly coherence in the southern Beaufort Sea [PDF]
Geophysical Research Letters, 2005 The circumpolar flaw lead polynya system is a region of enhanced biological productivity and for significant portions of the annual cycle, dominates the exchange of energy and mass across the ocean‐sea ice‐atmosphere (OSA) interface. We investigate the nature of sea ice concentration (SIC) anomalies for spatial and temporal statistical persistence ...
