The Sea Ice Analysis Tool allows users to analyze monthly-averaged or daily sea ice extent and concentration via interactive maps. In addition, users can plot monthly ice extent anomalies, map sea ice concentration anomalies, and display images of trends in sea ice concentration, all for a variety of date, climatology, and trend ranges. N.B. Per the University of Bremen: Thin sea ice occurs during the freezing season. In the melting season, the thickness of sea ice is highly variable and the emission properties in the microwave change due to the wetness of the surface and occurrence of melt ponds in the Arctic. Therefore, thickness data are calculated only during the freezing. The climate of the Arctic is characterized by long, cold winters and short, cool summers. There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winter. Some parts of the Arctic are covered by ice (sea ice, glacial ice, or snow) year-round, and nearly all parts of the Arctic experience long periods with.   As in recent winters, ice extent was well below normal in the Barents Sea, compensating for the extensive ice in the Bering Sea. As discussed in previous posts, the high Bering Sea ice extent this winter stemmed from unusually low air temperatures and persistent winds that helped to .

  Historic variations in Arctic sea ice is a series that attempts to determine the arctic warming events through the Holocene which commenced some years ago. Part 1 covered the warm period from approx. to This paper – Part 2 – examines the period of warming with a decade long overlap.   Below is the global ice extent on 7 April Note that while ice is gone from the Gulf of St. Lawrence, polar bears seldom venture that far south, as is also true for the southern Bering Sea in the western Arctic, where the ice will likely retreat north quickly. The high-latitudinal albedo bias is associated with the biases in sea-ice and snow (Figure 3a), in which we see that sea ice cover over Barents Sea, Gulf of Alaska and the Antarctic are.

  In any case, most Arctic sea ice melts in the summer before reaching its minimum annual extent in the fall, which means that summer weather and currents had the greatest impact on the extent of ice in the Arctic north of Europe. Because sea ice retreated from Svalbard in the summer, it was also the crucial season for whaling. The alarms are sounding about lack of ice extent in the Bering Sea, studiously ignoring what else is happening in the Arctic. For instance, the above image shows the last 10 days on the European side, with the Barents Sea on the right growing steadily to a new maximum. Nominal ice melting equates to nominal sea level rise from glacial melt water. All these facts tie together and helped confirm their reliability. During this same to time frame, the extent and mass of the polar ice caps diminished very slightly, again correlating . munity of Wales in Bering Strait (Fig. a). The different ice types, open water, (pixel) in the satellite imagery typically used to determine ice concentration and extent for studies of sea ice climatology. Several of these pixels, 25 by 25 km in extent, are shown in Fig. b, for a satellite scene 15 Indigenous Knowledge and Sea File Size: KB.
