The Arctic Coastal Erosion Model: Overview, Developments, and Calibration at Drew Point, Alaska
Abstract Permafrost coastlines are experiencing significant erosion as polar amplification has enhanced the effects of climate change in the Arctic. Warmer temperatures are increasing thermo‐denudation and more energetic oceans are increasing thermo‐abrasion in unlithified, ice‐bonded permafrost coastlines which comprise at least 40% of the circum ...

Accelerating thermokarst lake changes on the Qinghai-Tibetan Plateau
Abstract As significant evidence of ice-rich permafrost degradation due to climate warming, thermokarst lake was developing and undergoing substantial changes. Thermokarst lake was an essential ecosystem component, which significantly impacted the global carbon cycle, hydrology process and the stability of the Qinghai-Tibet Engineering Corridor.

Past and present thermokarst lake dynamics in the Yedoma Ice Complex region of North-Eastern Yakutia [PDF]
Thermokarst lakes are typical components of the yedoma-alas dominated relief in the coastal lowlands of North- Eastern Yakutia and formed as a result of thawing Late Pleistocene ice-rich Yedoma Ice Complex (IC) deposits.

Abstract Arctic lake, bay and lagoon ice regimes play a crucial role in understanding permafrost stability, hydrology, and carbon cycling in permafrost regions. This study integrates field and Synthetic Aperture Radar (SAR) data from Sentinel‐1 to improve the classification of Arctic lake, bay and lagoon ice regimes, with a particular focus on the ...

Multiyear measurements of ebullitive methane flux from three subarctic lakes [PDF]
Ebullition (bubbling) from small lakes and ponds at high latitudes is an important yet unconstrained source of atmospheric methane (CH4). Small water bodies are most abundant in permanently frozen peatlands, and it is speculated that their emissions will

Retrogressive Thaw Slumps Produce a Changing Disturbance Regime for Arctic Stream Invertebrates
Climate change is causing permafrost to thaw, resulting in the formation of large craters in the ground called thaw slumps, which deposit sediments and nutrients into rivers and continually impact stream ecosystems over time. We returned to slump impacted streams 10 years after an initial sample period and found that slumps permanently change streams ...

Deep Yedoma permafrost: A synthesis of depositional characteristics and carbon vulnerability [PDF]
Permafrost is a distinct feature of the terrestrial Arctic and is vulnerable to climate warming. Permafrost degrades in different ways, including deepening of a seasonally unfrozen surface and localized but rapid development of deep thaw features ...

Abstract Permafrost degradation under a warming climate has altered hydrological and biogeochemical processes across the Arctic. Although increasing fluxes of weathering‐derived ions (e.g., Ca2+, Mg2+, and SO42−) have been reported in Arctic rivers, the underlying mechanisms and hotspots within basins remain poorly understood due to limited analysis of
