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.

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.

Arctic Landscapes in Transition: Responses to Thawing Permafrost
Joel C. Rowland,Charles Jones,G. Altmann,R. Bryan,Benjamin T. Crosby,Larry D. Hinzman,D. L. Kane,David M. Lawrence,A. Mancino,Philip Marsh,James P. McNamara,V. E. Romanvosky,Horacio Toniolo,Bryan J. Travis,Erin Trochim,Cathy J. Wilson,G. L. Geernaert +16 more
TL;DR: In this paper, the authors show that over the past several decades, geomorphic processes in the Arctic have been changing or intensifying due to global warming and that lakes, ponds, and wetlands appear to be more dynamic, growing in some areas, shrinking in others, and changing distribution across lowland regions.
BookDOI
Long-term environmental change in Arctic and Antarctic lakes
TL;DR: Pienitz et al. as discussed by the authors introduced the concept of high-latitude lake sediments as a proxy for high-altitude lakes and proposed a method to obtain high-level geochronology of high latitude lakes.
Journal ArticleDOI
Reduction in areal extent of high-latitude wetlands in response to permafrost thaw
TL;DR: In this article, model simulations suggest that the areal extent of wetlands declines when permafrost thaws, and that wetlands take up and store carbon, and release methane through the decomposition of organic matter.

Future Changes in Northern Hemisphere Snowfall
TL;DR: In this article, the authors used simulations performed with 18 coupled atmosphere-ocean global climatemodels from phase 5 of the Coupled Model Intercomparison Project (CMIP5), and analyzed the Northern Hemisphere snowfall under the representative concentration pathway (RCP4.5) scenario for the period 2006 to 2100.

TL;DR: In this article, a comparison of Landsat multispectral scanner (MSS) imagery from the mid-1970s to Landsat 7 enhanced thematic mapper (ETM+) imagery from around 2000 shows that 50 lakes completely or partially drained over the approximately 25 year period, indicating landscape stability.
