values. While the sea-ice extent was reduced in the Arctic marginal seas in the early and middle Holocene (Extended Data Fig. 2), central Arctic site B28 was probably perennially ice covered throughout the Holocene39, suggesting that higher early and middle Holocene nitrate consumption occurred ...
The ice concentration data are used to calculate ice extent, which is the sum of the areas of all pixels in the region of interest containing at least 15% sea-ice concentration. Ice extents have been determined for the Arctic and the Antarctic for each month since November 1978 and have ...
(Bottom) Time series of annual Arctic sea ice extent (solid curve; 106 km2) and its 1979–1989 climatology (dashed curve). We use the ERSSTv3b data to estimate the long-term trend, and there are appreciable differences among SST data sets. Fig. 2 compares the 1880–2011 linear trend ...
This publication is the 19th edition of the Arctic sea-ice atlases prepared by the JIC. The atlas contains weekly charts depicting Northern Hemisphere and Great Lakes ice conditions and extent. The significant use of high resolution satellite imagery, combined with valuable ice reconnaissance data ...
Exactly at the same time the summer season got a sea ice extent never observed and 1 ½ years later the biggest temperature jump in the Northern North Atlantic and adjacent sector in the Arctic ever observed (Fig.14). First QUESTION: What was the role and impact of navel war on the se...

The well-documented decrease in the annual minimum Arctic sea ice extent over the past few decades is an alarming indicator of current climate change. However, much less is known about the thickness of the Arctic sea ice. Developing accurate forecasting models is critical to better predict its ...
CNNs) to improve vegetation classification for field-scale products. We believe that the publicly available data (Alaskan Existing Vegetation Type (AKEVT) map) over our study region is inaccurate at the field-scale level (e.g., <2 km2), since this was prepared for a large extent of Alaska...
The satellite record analysis for monthly differences of Arctic sea ice extent (SIE) shows that the most significant accelerated monthly sea ice reduction occurred between June and July although, on ...
