Long-term characteristics of ice phenology in Karelian lakes [PDF]

open access: yesEstonian Journal of Earth Sciences, 2013
The statistical relationships between lake ice phenology (freeze and break-up dates, ice duration), air temperature and North Atlantic Oscillation (NAO) index are analysed for eight lakes in Karelia from 1950 to 2009.

Climate change and Northern Hemisphere lake and river ice phenology from 1931–2005 [PDF]

open access: yesThe Cryosphere, 2021
At high latitudes and altitudes one of the main controls on hydrological and biogeochemical processes is the breakup and freeze-up of lake and river ice.

Potential of GNSS-R for the Monitoring of Lake Ice Phenology

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article introduces the first use of global navigation satellite system (GNSS) reflectometry for monitoring lake ice phenology. This is demonstrated using Qinghai Lake, Tibetan Plateau, as a case study.

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

open access: yesEcosphere
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 ...

Monitoring Bedfast Ice and Ice Phenology in Lakes of the Lena River Delta Using TerraSAR-X Backscatter and Coherence Time Series

open access: yesRemote Sensing, 2016
Thermokarst lakes and ponds are major elements of permafrost landscapes, occupying up to 40% of the land area in some Arctic regions. Shallow lakes freeze to the bed, thus preventing permafrost thaw underneath them and limiting the length of the period ...

Evaluating RADARSAT-2 for the Monitoring of Lake Ice Phenology Events in Mid-Latitudes [PDF]

open access: yesRemote Sensing, 2018
Lake ice is an important component in understanding the local climate as changes in temperature have an impact on the timing of key ice phenology events. In recent years, there has been a decline in the in-situ monitoring of lake ice events in Canada and

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

open access: yesEarth 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

open access: yesRemote 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]

open access: yesThe 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]

open access: yesScience 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 ...
