Despite a century of warming, increased snowfall has buffered the ice phenology of North America’s largest high-elevation lake against climate change

Environmental Research Letters
Lakes are sentinels of environmental change. In cold climates, lake ice phenology—the timing and duration of ice cover during winter—is a key control on ecosystem function.

Water temperature, mixing, and ice phenology in the arctic–alpine Lake Darfáljávri (Lake Tarfala), northern Sweden

Arctic, Antarctic, and Alpine Research
In the rapidly warming circumpolar Arctic, recent research of lakes has focused on their climatology and ecology but is challenged by sparsity of wintertime data. At the c. 48-m-deep and c.

Ice Phenology and Thickness in Small Arctic Lakes: Field Observations and Mechanistic Controls

Water Resources Research
The Arctic is the fastest‐warming region globally. Lake ice is a sentinel indicator of Arctic change, with wide impacts on hydrological regimes, biodiversity, and ecosystem services.

Variable phenology but consistent loss of ice cover on 1213 Minnesota lakes

Limnology and Oceanography Letters
Lake ice cover is declining globally with important implications for lake ecosystems. Ice loss studies often rely on small numbers of lakes with long‐term data. We analyzed variation and trends in ice cover phenology from 1213 lakes over 74 yr (1949–2022)

Understanding two key processes associated with alpine lake ice phenology using a coupled atmosphere-lake model

Journal of Hydrology: Regional Studies, 2023
Study region: Lake Nam-Co, a typical deep alpine lake in the central of Tibetan Plateau. Study focus: This study investigates the role of surface turbulent fluxes in simulating lake freeze-up and the role of solar radiation transfer (when lake ice exists) in simulating the lake ice break-up.

Phenological Changes and Driving Forces of Lake Ice in Central Asia from 2002 to 2020

Remote Sensing, 2022
Lake ice phenology is an indicator of past and present climate, it is sensitive to regional and global climate change. In the past few decades, the climate of Central Asia has changed significantly due to global warming and anthropogenic activities ...

Variation in Ice Phenology of Large Lakes over the Northern Hemisphere Based on Passive Microwave Remote Sensing Data

Remote Sensing, 2021
Ice phenology data of 22 large lakes of the Northern Hemisphere for 40 years (1979–2018) have been retrieved from passive microwave remote sensing brightness temperature (Tb). The results were compared with site-observation data and visual interpretation

An automated method to monitor lake ice phenology [PDF]

Limnology and Oceanography: Methods, 2011
A simple method to automatically measure the date of ice‐on, the date of ice‐off, and the duration of lake ice cover is described. The presence of ice cover is detected by recording water temperature just below the ice/water interface and just above the lake bottom using moored temperature sensors.

Arctic-Boreal Lake Phenology Shows a Relationship between Earlier Lake Ice-Out and Later Green-Up [PDF]

Remote Sensing, 2021
Satellite remote sensing has transformed our understanding of Earth processes. One component of the Earth system where large uncertainties remain are Arctic and boreal freshwater lakes. With only short periods of open water due to annual ice cover, lake productivity in these regions is extremely sensitive to warming induced changes in ice cover. At the

Spatiotemporal characteristics of Qinghai Lake ice phenology between 2000 and 2016 [PDF]

Journal of Geographical Sciences, 2019
Lake ice phenology is considered a sensitive indicator of regional climate change. We utilized time series information of this kind extracted from a series of multi-source remote sensing (RS) datasets including the MOD09GQ surface reflectance product, Landsat TM/ETM+ images, and meteorological records to analyze spatiotemporal variations of ice ...
