Tundra recovery post-fire in the Yukon–Kuskokwim Delta, Alaska
The extent of wildfires in tundra ecosystems has dramatically increased since the turn of the 21st century due to climate change and the resulting amplified Arctic warming. We simultaneously studied the recovery of vegetation, subsurface soil moisture, and active layer thickness (ALT) post-fire in the permafrost-underlain uplands of the Yukon–Kuskokwim Delta in southwestern Alaska to understand the interaction between these factors and their pote…
Isotopic seasonality of fluvial-derived greenhouse gases implies active layer deepening
Climate change in the northern circumpolar regions is rapidly thawing organic-rich permafrost soils, leading to the substantial release of dissolved CO 2 and CH 4 into river systems. This mobilization impacts local ecosystems and regional climate feedback loops, playing a crucial role in the Arctic carbon cycle. Here, we analyze the stable carbon ( δ 13 C) and radiocarbon (F 14 C) isotopic compositions of dissolved CO 2 and CH 4 in the Sagavanirk…
Do beaver ponds increase methane emissions along Arctic tundra streams
Beaver engineering in the Arctic tundra induces hydrologic and geomorphic changes that are favorable to methane (CH 4 ) production. Beaver-mediated methane emissions are driven by inundation of existing vegetation, conversion from lotic to lentic systems, accumulation of organic rich sediments, elevated water tables, anaerobic conditions, and thawing permafrost. Ground-based measurements of CH 4 emissions from beaver ponds in permafrost landscape…
Arctic-boreal lakes of interior Alaska dominated by contemporary carbon
Northern high-latitude lakes are critical sites for carbon processing and serve as potential conduits for the emission of permafrost-derived carbon and greenhouse gases. However, the fate and emission pathways of permafrost carbon in these systems remain uncertain. Here, we used the natural abundance of radiocarbon to identify and trace the predominant sources of methane, carbon dioxide, dissolved inorganic and organic carbon in nine lakes within…
Tundra fire increases the likelihood of methane hotspot formation in the Yukon–Kuskokwim Delta, Alaska, USA
Rapid warming in Arctic tundra may lead to drier soils in summer and greater lightning ignition rates, likely culminating in enhanced wildfire risk. Increased wildfire frequency and intensity leads to greater conversion of permafrost carbon to greenhouse gas emissions. Here, we quantify the effect of recent tundra fires on the creation of methane (CH 4 ) emission hotspots, a fingerprint of the permafrost carbon feedback. We utilized high-resoluti…
Geomorphological patterns of remotely sensed methane hot spots in the Mackenzie Delta, Canada
We studied geomorphological controls on methane (CH 4 ) hotspots in the Mackenzie Delta region in northern Canada using airborne imaging spectroscopy collected as part of the Arctic Boreal Vulnerability Experiment. Methane emissions hotspots were retrieved at ∼25 m 2 spatial resolution from a ∼10 000 km 2 NASA’s Next Generation Airborne Visible/Infrared Imaging Spectrometer survey of the Mackenzie Delta acquired 31 July–3 August 2017. Separating …
