Sea ice concentration . Sea ice concentration is the fraction of an observational area covered completely by sea ice. Sea ice extent . Sea ice extent represents the total area covered partially or totally by sea ice. For remote sensing applications, a lower threshold of 15 % in the fraction ...

a, Sea ice concentration (SIC) trends over 1979−2014, which are linearly congruent with the observed IPO and AMV trends over 1979−2014. The congruent trends are estimated by summing over the multiplicative products of the observed IPO trend and the regression coefficient for the IPO at eac...
53Altmetric Metrics Abstract Decline in winter sea-ice concentration (SIC) in the Barents-Kara Sea significantly impacts climate through increased heat release to the atmosphere. However, the past Barents-Kara SIC decrease rate is underestimated in the majority of Coupled Model Intercomparison Project ...

Fig. 2. Map of sea-ice concentration off Lützow–Holm Bay from SSM/I data in early December (1–10 Dec) for (a) the mean of 1989–2012 and (b) 2011, and in late December (21–31 Dec) for (c) the mean of 1989–2012 and (d) 2011. 2. Data and methods This study uses dat...
Application of a similar filter for use with sea-ice concentration maps derived with the special-sensor microwave imager (SSM/I) sensor is less successful. This results from the position of the 19.35 GHz SSM/I channels, which are closer to the center of the 22.2 GHz atmospheric water-vapor ...
These data demonstrate congruent increase in sea-ice concentration/persistence and wind stress-related sea-surface turbulence in the two regions since 7 cal ka BP, with a particularly strong signal since 4.5–3.5 cal ka BP. Comparison of these high latitude records with sea ice and turbulence ...
1740 m MSL) and sea-level in close proximity to the coring sites (82.5 °N, 55 °W, 0 m MSL) (Fig.4). The annual mean sea-ice concentration (1978–2021) was extracted from the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS)65(Fig.3). Sea-ice concentration data ...
A classification system for obtaining the sea ice concentration from satellite based single-polarized SAR data is presented. The method is based on a supervised neural network classification of second-order grey level statistics features. Learning Vector Quantization is used for describing the boundaries...
