Phenology, food webs, and fish: The effects of shifted ice phenology across multiple trophic levels

Ecosphere
Winter plays a crucial role in structuring temperate aquatic ecosystems, influencing the timing of multiple processes across trophic levels including phytoplankton blooms, zooplankton production, and the reproduction and recruitment of fish species like ...

Ice phenology interactions with water and air temperatures in high mountain lakes

Science of the Total Environment
Ice phenology is of great importance for the thermal structure of lakes and ponds and the biology of lake species. Under the current climate change conditions, ice-cover duration has been reduced by an advance in ice-off, and a delay in ice-on, and future projections foresee this trend as continuing.

Influence of Atmospheric Rivers on Lake Ice Phenology in the Northern Hemisphere

Geophysical Research Letters
Atmospheric rivers (ARs) can rapidly alter regional hydrothermal conditions and directly affect lake ice. This study presents the first assessment of AR impacts on lake ice phenology across the Northern Hemisphere. AR events were associated with positive

A 41-year (1979–2019) passive-microwave-derived lake ice phenology data record of the Northern Hemisphere [PDF]

Earth System Science Data, 2022
Seasonal ice cover is one of the important attributes of lakes in middle- and high-latitude regions. The annual freeze-up and breakup dates as well as the duration of ice cover (i.e., lake ice phenology) are sensitive to the weather and climate; hence ...

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 ...

Geographic variation and temporal trends in ice phenology in Norwegian lakes during the period 1890–2020 [PDF]

The Cryosphere, 2021
Long-term observations of ice phenology in lakes are ideal for studying climatic variation in time and space. We used a large set of observations from 1890 to 2020 of the timing of freeze-up and break-up, and the length of ice-free season, for 101 ...

Sea-ice algal phenology in a warmer Arctic [PDF]

Science Advances, 2019
<p>The Arctic sea-ice decline is among the most emblematic manifestations of climate change and is occurring before we understand its ecological consequences. We investigated future changes in algal productivity combining a biogeochemical model for sympagic algae with sea-ice drivers from an ensemble of 18 CMIP5 climate models ...

Satellite microwave assessment of Northern Hemisphere lake ice phenology from 2002 to 2015 [PDF]

The Cryosphere, 2017
A new automated method enabling consistent satellite assessment of seasonal lake ice phenology at 5 km resolution was developed for all lake pixels (water coverage  ≥  90 %) in the Northern Hemisphere using 36.5 GHz H-polarized brightness temperature (Tb)

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.
