Journal ArticleDOI
Assessing the influence of lake and watershed attributes on snowmelt bypass at thermokarst lakes
TL;DR: In this paper , isotope data were used to estimate the amount of lake water replaced by freshet and to observe how the water sources of lakes changed in response to the freshet.

Modern Eastern Canadian Arctic Lake Water Isotopes Exhibit Latitudinal Patterns in Inflow Seasonality and Minimal Evaporative Enrichment
TL;DR: In this paper , the authors used modern lake water isotopes (δ18O and δ2H) collected between 1994-1997 and 2017-2021 from a transect of sites spanning a Québec-to-Ellesmere Island gradient to evaluate the effects of inflow seasonality and evaporative enrichment on the lake water composition of lake water.

Ecosystem responses of shallow thermokarst lakes to climate-driven hydrological change: Insights from long-term monitoring of periphytic diatom community composition at Old Crow Flats (Yukon, Canada).
Wathiq Jassim Mohammed,Lauren A. MacDonald,Kathryn E. Thomas,Ian McDonald,Kevin W. Turner,Brent B. Wolfe,Roland I. Hall +6 more
TL;DR: In this article , periphytic diatom community composition in biofilms accrued on artificial-substrate samplers at 14 lakes collected mostly annually during 2008-2019 CE was analyzed.
Journal ArticleDOI
Hydrological, meteorological, and watershed controls on the water balance of thermokarst lakes between Inuvik and Tuktoyaktuk, Northwest Territories, Canada
TL;DR: In this article , water isotope data were used to calculate the average isotope composition of lake source water (δI) and the ratio of evaporation to inflow (E/I).

Liquid-vapor fractionation of oxygen and hydrogen isotopes of water from the freezing to the critical temperature
Juske Horita,David J. Wesolowski +1 more
TL;DR: In this paper, the equilibrium fractionation factors of oxygen and hydrogen isotopes between liquid water and water vapor have been precisely determined from 25 to 350°C on the VSMOW-SLAP scale.

Shrinking thermokarst ponds and groundwater dynamics in discontinuous permafrost near council, Alaska
Kenji Yoshikawa,Larry D. Hinzman +1 more
TL;DR: In this article, the authors used synthetic aperture radar (SAR) data for classification of terrain units and surface water properties, while historical aerial photographs and satellite images (IKONOS) were used for assessment of pond shrinking and recent thermokarst progression.

Effects of climate change on the freshwaters of arctic and subarctic north america
Wayne R. Rouse,Marianne S. V. Douglas,Robert E. Hecky,Anne E. Hershey,George W. Kling,Lance F. W. Lesack,Philip Marsh,Michael P. McDonald,Barbara J. Nicholson,Nigel T. Roulet,John P. Smol +10 more
TL;DR: In this paper, the authors studied the effect of climate change on the water balance in the arctic and subarctic regions of North America and found that precipitation changes will play an important role in precipitation changes associated with climate warming.
Journal ArticleDOI
Crossing the final ecological threshold in high Arctic ponds
TL;DR: Findings that some high Arctic ponds, which paleolimnological data indicate have been permanent water bodies for millennia, are now completely drying during the polar summer are described, linking the disappearance of the ponds to increased evaporation/precipitation ratios probably associated with climatic warming.

Spring snow cover extent reductions in the 2008–2012 period exceeding climate model projections
Chris Derksen,Ross Brown +1 more
TL;DR: In this article, the authors analyzed the Northern Hemisphere spring terrestrial snow cover extent (SCE) from the NOAA snow chart Climate Data Record (CDR) for the April to June period (when snow cover is mainly located over the Arctic) has revealed statistically significant reductions in May and June SCE.
