Assessing the influence of lake and watershed attributes on snowmelt bypass at thermokarst lakes [PDF]

open access: yesHydrology and Earth System Sciences, 2022
Snow represents the largest potential source of water for thermokarst lakes, but the runoff generated by snowmelt (freshet) can flow beneath lake ice and via the outlet without mixing with and replacing pre-snowmelt lake water.

Identifying Thermokarst Lakes Using Deep Learning and High-Resolution Satellite Images

open access: yesScience of Remote Sensing
Thermokarst lakes play a critical role in hydrologic connectivity, permafrost stability, and carbon exchange from local to regional scales. Due to the typically small sizes and highly dynamic nature of thermokarst lakes, their identification in large ...

Estimating nutrient stoichiometry and cascading influences on plankton in thermokarst lakes on the Qinghai-Tibet Plateau

open access: yesCommunications Earth & Environment
Thermokarst lakes play a critical role in global biogeochemistry. Here we delved into nutrient stoichiometry and its cascading effects on plankton communities across thermokarst lakes on the Qinghai-Tibet Plateau.

Arctic Thermokarst Lakes – Carbon Comes and Goes [PDF]

open access: yes
This PhD project focused on the physical and biogeochemical variability of Arctic thermokarst lake sediments and the resulting impact on the greenhouse gas (GHG) emissions of these lakes. A better understanding of this topic is of importance because thermokarst lakes induce large-scale erosion of sediment organic carbon (SOC) along their shorelines ...

Chemoautotrophic carbon fixation in thermokarst lakes on the Tibetan Plateau. [PDF]

open access: yesNat Commun
Dissolved organic carbon (DOC) derived from thermokarst lakes is usually considered to be prone to microbial degradation and releases substantial carbon dioxide to the atmosphere, potentially enhancing the positive permafrost carbon (C)-climate feedback.

Roles of Thermokarst Lakes in a Warming World [PDF]

open access: yesTrends in Microbiology, 2020
Permafrost covers a quarter of the northern hemisphere land surface and contains twice the amount of carbon that is currently present in the atmosphere. Future climate change is expected to reduce its near-surface cover by over 90% by the end of the 21st century, leading to thermokarst lake formation.

Lake‐Atmosphere Heat Flux Dynamics of a Thermokarst Lake in Arctic Siberia [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2018
AbstractWe conducted eddy covariance measurements from April to August 2014 on a Siberian thermokarst lake. The study site is located in the Lena River Delta and characterized as a floating ice lake. Heat fluxes differed in magnitudes, directions and temporal patterns depending on the lake surface conditions (“frozen” ice cover, ice cover melt, and ...

Ecological stability of zooplankton communities in changing arctic lakes over three decades. [PDF]

open access: yesEcology
Abstract In the Arctic, rapid warming is altering disturbance regimes, creating an urgent need to assess the ecological stability of these relatively pristine ecosystems. The Arctic landscape has thousands of lakes that are experiencing both gradual, persistent disturbances (e.g., warming) and increased frequency and intensity of pulse disturbances (e ...

Thermokarst Lake Susceptibility Assessment Induced by Permafrost Degradation in the Qinghai–Tibet Plateau Using Machine Learning Methods

open access: yesRemote Sensing, 2023
The rapidly warming climate on the Qinghai–Tibet Plateau (QTP) leads to permafrost degradation, and the thawing of ice-rich permafrost induces land subsidence to facilitate the development of thermokarst lakes.
