根据第一段第一句话"Scientists say "extreme" warm air high over the Arctic Ocean this week is melting sea ice and sending very cold air to Europe.(科学家说,本周北冰洋上空的“极端”暖空气正在融化海冰,并向欧洲输送非常冷的空气。)"可知,北冰洋的高气温融化了海冰并且往欧洲输送了冷空气,所以欧洲...
The field of Arctic sea ice prediction on “weather time scales” is still in its infancy with little existing understanding of the limits of predictability. This is especially true for sea ice deformation along so-called Linear Kinematic Features (LKFs) including leads that are relevant for marin...
Siberian Sea, while SIT presented a larger downward trend in the northern Canadian Archipelago, northern Greenland, and the East Siberian Sea. Regarding to the seasonal trend of sea ice on sub-region scale, the reduction rate of SIA exhibited an apparent spatial heterogeneity among seasons, especi...

The spatial distribution of the average pan-Arctic lead frequencies reveals, moreover, distinct patterns of predominant fracture zones in the Beaufort Sea and along the shelf-breaks, mainly in the Siberian sector of the Arctic Ocean as well as the well-known polynya and fast-ice locations. ...
Satellite passive-microwave data for November 1978 through December 1996 reveal marked seasonal, regional, and interannual variabilities, with an overall decreasing trend of 34,300±3700 km2/yr (2.8%/decade) in Arctic sea ice extents over the 18.2-year period. Decreases occur in all seasons and ...
For areas that are sea ice cover as observed by SAR but they are not masked by the IMS (either due to the uncertainty of the IMS data or due to drift of sea ice over time), the subsequent processing step involving a homogeneity test after sea ice masking can further discard these ...

Here we produce Arctic sea ice biomarker proxy records for the penultimate glacial (Marine Isotope Stage 6) and the subsequent last interglacial (Marine Isotope Stage 5e). The latter is a time interval when the high latitudes were significantly warmer than today. We document that even under such...
