Siberian Shelf - Wikipedia
The Siberian Shelf is a coastal shelf in the Arctic Ocean and is the largest continental shelf of the Earth, a part of the continental shelf of Russia. It extends from the continent of Eurasia in the general area of North Siberia (hence the name) into the Arctic Ocean .
Fires Char the Siberian Arctic - NASA Earth Observatory
2024年7月18日 · “Fires are a natural part of boreal and high Arctic landscapes in Sakha and the broader Siberian Arctic,” said Kevin Smith, a U.S. Forest Service plant physiologist and co-author of a 2022 analysis of wildland fire activity in the Siberian Arctic. “However, the frequency, severity, and area encompassed by current wildfire conditions are ...
Remobilization of dormant carbon from Siberian-Arctic ... - Science
This amplified permafrost carbon release by one order of magnitude, particularly during the last deglaciation when global sea-level rise caused rapid flooding of the land area thereafter constituting the vast East Siberian Arctic Shelf.
Early snowmelt and polar jet dynamics co-influence recent …
2022年11月3日 · We show that early snowmelt together with an anomalous Arctic front jet over northeastern Siberia promoted unusually warm and dry surface conditions, followed by anomalously high lightning and fire activity. Since 1966, spring snowmelt has started 1.7 days earlier each decade.
Extensive fires in southeastern Siberian permafrost linked to
2020年1月8日 · Here, we analyze fire activity and relevant large-scale atmospheric conditions over southeastern Siberia, which has the largest burned area fraction in the circumboreal and high-level carbon emissions due to high-density peatlands.
Wildfires in the Siberian Arctic - MDPI
2022年7月21日 · Arctic soils naturally store large quantities of C, as peat has formed throughout the Holocene. For the Siberian Arctic, we used observations from the MODIS remote sensing instrument to document changes in frequency, geographic extent, and seasonal timing of wildfires as well as vegetation productivity (GPP, NPP, EVI).
Siberian Arctic black carbon: gas flaring and wildfire impact
2022年5月6日 · The largest oil and gas producing regions of northwestern Siberia are located along the main low-level pathway of air masses entering the Arctic and thus make a disproportionally large contribution to the Arctic lower troposphere (Stohl, 2006).
Large transboundary health impact of Arctic wildfire smoke - Nature
2024年4月13日 · Rapid warming at high latitudes, particularly in Siberia, has led to large wildfires in recent years that cause widespread smoke plumes. These fires lead to substantial deterioration in summer...
Methane Releases From Arctic Shelf May Be Much Larger and …
2010年3月4日 · The East Siberian Arctic Shelf is a methane-rich area that encompasses more than 2 million square kilometers of seafloor in the Arctic Ocean. It is more than three times as large as the nearby Siberian wetlands, which have been considered the primary Northern Hemisphere source of atmospheric methane.
Arctic Warming Is Driving Siberian Wildfires - Eos
2024年9月19日 · Wildfire activity in central Siberia, Russia, has doubled in the past 2 decades, scorching vast areas of forest and releasing carbon stored in the rich soils and permafrost underneath. The...
