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 ...
Our simulation efforts reveal similar boreal spring (March) sea ice extent in the LIG time slices as in the PI simulation. While sea ice concentrations were slightly lower in June during the early LIG (130 ka) and the middle LIG (125 ka) compared to PI concentrations, the largest ...
sediment-laden ice differ substantially from those of clean ice and that sediment tends to accumulate at the ice surface during the first melt season, remote-sensing techniques provide a valuable tool for mapping the extent of particle-laden ice in the Arctic basin and assessing its particulate ...
global warming has led to widespread shrinking of the cryosphere, with mass loss from ice sheets and glaciers (very high confidence), reductions in snow cover (high confidence) and Arctic sea ice extent and thickness (very high confidence), and increased permafrost temperature (very high confidence...
(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 ...
Arctic sea ice drift; neXtSIM; ensemble forecasting; wind perturbation; ice cohesion perturbation Graphical Abstract1. Introduction Sea ice covering the polar oceans is an important component of the Earth System. The dramatic changes in sea ice extent and volume in the Arctic have been regularly ...
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 ...
The effects of this storm on the sea ice concentration maps are in plain sight. Slowly sea ice area and extent data are trickling in and for now the changes are quite large. The sea ice extent chart from theDanish Meteorological Instituteis showing huge drops and has almost reached a new ...
(3) What are the possible effects of different configurations of the CMIP6 models (coarse/fine resolution etc.) on the simulations of snow depth over Arctic sea ice? 2. Data 2 2.1. Satellite-derived snow depth --> 2.1. Satellite-derived snow depth ...
