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

An Automatic Method to Detect Lake Ice Phenology Using MODIS Daily Temperature Imagery
Remote Sensing, 2021 Lake ice phenology is a climate-sensitive indicator. However, ground-based monitoring suffers from the limitations of human vision and the difficulty of its implementation in harsh environments.

Atmospheric circulation and its impact on ice phenology in Scandinavia [PDF]
, 2004 Atmospheric circulation is important in affecting surface climate and ecosystems. In this study, we compared the impact of north-atlantic and regional atmospheric circulation, as represented by the North Atlantic Oscillation (NAO) index and a set of regional circulation indices, on ice phenology of 50 Scandinavian lakes.

Ice Phenology in Eurasian Lakes over Spatial Location and Altitude [PDF]
Water, 2022 Eurasian freezing lakes cover an almost 180° wide longitude sector between the latitudes 30° and 75° N, and their altitudes range from below the sea surface level up to 5 km elevation. Ice phenology varies widely in this region. However, these variations and their influence factors have been little studied.

Potential of GNSS-R for the Monitoring of Lake Ice Phenology
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingThis 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.

The ice phenology as a predictor of Planktothrix rubescens bloom in vegetation season in temperate lakes. [PDF]
Front MicrobiolIntroductionGlobal warming affects air and water temperatures, which impacts the phenology of lakes and aquatic ecosystems. These changes are most noticeable during winter, when the potentially toxic Planktothrix rubescens forms its inoculum for annual blooms. Mostly, research has been conducted on alpine lakes, where blooms have persisted for decades,

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

Beavers on Ice: Factors Influencing Emergence Phenology in Boreal Canada. [PDF]
Glob Chang BiolABSTRACT The influence of climate change on emergence phenology of hibernating mammals in northern latitudes is receiving increased attention, yet for freshwater semi‐aquatic mammals such as beavers, which do not hibernate and therefore maintain an obligatory dependence on freshwater habitats throughout the year, little is known about

Shorter Ice Duration and Changing Phenology Influence Under-Ice Lake Temperature Dynamics. [PDF]
J Geophys Res BiogeosciAbstractTemperate lakes worldwide are losing ice cover but the implications for under‐ice thermal dynamics are poorly constrained. Using a 92‐year record of ice phenology from a temperate and historically dimictic lake, we examined trends, variability, and drivers of ice phenology and under‐ice temperatures.
