Arctic sea ice decline contributes to thinning lake ice trend in northern Alaska

Environmental Research Letters, 2016
Field measurements, satellite observations, and models document a thinning trend in seasonal Arctic lake ice growth, causing a shift from bedfast to floating ice conditions. September sea ice concentrations in the Arctic Ocean since 1991 correlate well (

A Ten-Year Record of Supraglacial Lake Evolution and Rapid Drainage in West Greenland Using an Automated Processing Algorithm for Multispectral Imagery [PDF]

, 2013
The rapid drainage of supraglacial lakes introduces large pulses of meltwater to the subglacial environment and creates moulins, surface-to-bed conduits for future melt.

Ice thickness and water level estimation for ice-covered lakes with satellite altimetry waveforms and backscattering coefficients [PDF]

The Cryosphere, 2023
Lake ice, serving as a sensitive indicator of climate change, is an important regulator of regional hydroclimate and lake ecosystems. For ice-covered lakes, traditional satellite altimetry-based water level estimation is often subject to winter anomalies

Determining lake surface water temperatures worldwide using a tuned one-dimensional lake model (FLake, v1) [PDF]

, 2016
A tuning method for FLake, a one-dimensional (1-D) freshwater lake model, is applied for the individual tuning of 244 globally distributed large lakes using observed lake surface water temperatures (LSWTs) derived from along-track scanning radiometers ...

Mixing, stratification, and plankton under lake‐ice during winter in a large lake: Implications for spring dissolved oxygen levels

Limnology and Oceanography, 2020
The mixing and stratification present under ice‐covered lakes during winter can potentially influence the oxygen concentrations in the subsequent spring.

Scientific access into Mercer Subglacial Lake: scientific objectives, drilling operations and initial observations

Annals of Glaciology, 2021
The Subglacial Antarctic Lakes Scientific Access (SALSA) Project accessed Mercer Subglacial Lake using environmentally clean hot-water drilling to examine interactions among ice, water, sediment, rock, microbes and carbon reservoirs within the lake water

Shrinking sea ice, increasing snowfall and thinning lake ice: a complex Arctic linkage explained [PDF]

, 2016
The dramatic shrinkage of Arctic sea ice is one of the starkest symptoms of global warming, with potentially severe and far-reaching impacts on arctic marine and terrestrial ecology (Post et al 2013 Science 341 519–24) and northern hemisphere climate ...

Nonlinear temperature response of lake ice breakup [PDF]

, 2004
A uniquely comprehensive set of four decades of ice breakup data from 196 Swedish lakes covering 13degrees of latitude (55.7degrees N to 68.4degrees N) shows the relationship between the timing of lake ice breakup and air temperature to be an arc cosine ...
