Past and Future Changes in Arctic Lake and River Ice [PDF]

, 2011
Paleolimnological evidence from some Arctic lakes suggests that longer ice-free seasons have been experienced since the beginning of the nineteenth century.

Climate regulates alpine lake ice cover phenology and aquatic ecosystem structure [PDF]

Geophysical Research Letters, 2016
AbstractHigh‐elevation aquatic ecosystems are highly vulnerable to climate change, yet relatively few records are available to characterize shifts in ecosystem structure or their underlying mechanisms. Using a long‐term data set on seven alpine lakes (3126 to 3620 m) in Colorado, USA, we show that ice‐off dates have shifted 7 days earlier over the past

Brief communication: Improving lake ice modeling in ORCHIDEE-FLake model using MODIS albedo data [PDF]

The Cryosphere
The FLake lake model embedded in the ORCHIDEE land surface model was recently updated to better represent winter ice cover. MODIS albedo data and the Great Lakes ice cover fraction dataset over the Laurentian Great Lakes were used to calibrate and ...

Ice Concentration Scaling Laws for Freshwater Lakes in Numerical Weather and Climate Prediction

Geophysical Research Letters, 2023
If lake ice is assumed to deform and fail as a linear viscoelastic material under the action of wind stress, then a simple ice concentration scaling law can be constructed suitable for one‐dimensional lake models embedded within environmental prediction ...

Variations of Lake Ice Phenology Derived from MODIS LST Products and the Influencing Factors in Northeast China

Remote Sensing
Lake ice phenology serves as a sensitive indicator of climate change in the lake-rich Northeast China. In this study, the freeze-up date (FUD), break-up date (BUD), and ice cover duration (ICD) of 31 lakes were extracted from a time series of the land ...

Ecology under lake ice [PDF]

, 2016
Winter conditions are rapidly changing in temperate ecosystems, particularly for those that experience periods of snow and ice cover. Relatively little is known of winter ecology in these systems, due to a historical research focus on summer ‘growing ...

Investigating Changes in Chlorophyll a and Other Water Chemistry Variables in Response to Global Environmental Change [PDF]

, 2020
Changes in water quality are influenced by climate change and other anthropogenic stressors. We 1) assessed changes in water quality in lakes in the Laurentian Great Lakes region, and 2) compiled water quality data for lakes across the world to assess ...

Manifestation of climatic change in the ice phenology of Lake Ladoga over the past 55 years

Лëд и снег, 2021
The article presents results of monitoring changes in some phenological characteristics of the ice cover of Lake Ladoga over the past 55 years. A steady tendency has been observed for a decrease in the duration of ice formation and the area of fast ice ...
