Effects of deglaciation on circumpolar distribution of arctic vegetation
An understanding of the factors controlling the distribution of arctic vegetation will allow better prediction of the effects of climate change. This study examines the effect of the age of landscapes on the distribution of arctic vegetation. We compared time since deglaciation with the distribution of vegetation types and Advanced Very High Resolution Radiometer (AVHRR) satellite measures of g...
متن کاملCircumpolar Tundra and Its Largest Pan-Arctic river
The Arctic freshwater budget is critical for understanding the climate in the northern 22 regions. However, the hydrology of the Arctic circumpolar tundra region (ACTR) and the largest 23 pan-Arctic rivers are still not well understood. In the present paper, we analyze the spatiotemporal 24 variations in terrestrial water storage (TWS) of the ACTR, including three of its largest pan-Arctic 25 r...
متن کاملNDVI patterns and phytomass distribution in the circumpolar Arctic
The Circumpolar Arctic Vegetation Map (CAVM) was used to analyze the distribution of NDVI and phytomass in the Arctic, providing data for understanding arctic vegetation patterns, assessing change, and calibrating models. The dominant trend in the analysis of Normalized Difference Vegetation Index (NDVI) was a decrease from south to north, correlating with bioclimate subzones and vegetation uni...
متن کاملAssessing the carbon balance of circumpolar Arctic tundra using remote sensing and process modeling.
This paper reviews the current status of using remote sensing and process-based modeling approaches to assess the contemporary and future circumpolar carbon balance of Arctic tundra, including the exchange of both carbon dioxide and methane with the atmosphere. Analyses based on remote sensing approaches that use a 20-year data record of satellite data indicate that tundra is greening in the Ar...
متن کاملAdaptation in Arctic circumpolar communities: food and water security in a changing climate
The AMAP Human Health Assessment Group has developed different adaptation strategies through a long-term collaboration with all Arctic countries. Different adaptation strategies are discussed, with examples mainly from native population groups in Alaska.
