“…In Mohonk Lake, ice-on and ice duration changed twice as fast compared to other northern hemisphere lakes (Sharma et al, 2021) and the high rate of change was consistent with other mountain lakes, which show more rapid ice loss than lower-elevation systems (Christianson et al, 2021;Kainz et al, 2017). The rapid change in ice phenology was a result of regional and local climatic shifts.…”

Temperate lakes worldwide are losing ice cover, however implications for under-ice thermal dynamics are poorly constrained. Using a 90-year record of ice phenology from a temperate lake, we examined trends, variability, and drivers of ice phenology. The onset of ice formation decreased by 2.3 days decade-1 which can be largely attributed to warming air temperatures. Ice-off date has become substantially more variable with spring air temperatures and cumulative February through April snowfall explaining over 80% of the variation in timing. As a result of changing ice phenology, total ice duration consequently contracted by a month and more than doubled in variability. Using weekly under-ice temperature profiles for the most recent 36 years, shorter ice duration decreased winter inverse stratification and extended the spring mixing period. These results illustrate how changing ice phenology can affect summer thermal dynamics.

“…Lakes observed are similar in terms of their locations near population centers and lower elevations, which leads to a relatively homogenous group of observations. For example, we have little understanding or observations of lakes found in more remote, alpine regions (Christianson et al., 2021; Kainz et al., 2017; Pociask‐Karteczka & Choiński, 2012; Preston et al., 2016), or in the Southern Hemisphere. To branch out and observe a wider collection of lakes for a fuller understanding of lake ice phenology on a global scale, we require the use of newer technologies to fill gaps and expand observations, shifting from an intensive understanding of a single lake or grouping of lakes to an extensive summary of lake observations (Sharma, Meyer, et al., 2020).…”

Lake ice phenology is a critical component of the cryosphere and a sensitive indicator of climate change that has some of the longest records related to climate science. Records commenced for numerous reasons including navigation, hydropower development, and individual curiosity, demonstrating the value of lake ice as a seasonal event of significant importance to a broad swath of peoples and countries. At the same time, lake ice loss has been rapid and widespread with lakes losing ice at an average rate of 17 days per century. In this Perspective, we examine the earliest known records of ice cover and the scientific studies that developed from that practice of record keeping. Studies in lake ice began in the nineteenth Century and have included relationships between climate, biology, and ice cover. Early studies developed some of the foundational principles that limnologists and climate scientists are still exploring, such as the relationship between ice phenology and climate variables, large‐scale climate oscillations, and morphological characteristics, with implications for lake ice physical structure and under‐ice ecosystems in a warming climate. We conclude with an examination of the state of the field and how these centuries‐long lake ice records can continue to inform cutting edge science by validating satellite remote sensing techniques, in addition to modeling approaches and collaborations across disciplines, that can improve our understanding of the loss of lake ice in a warmer world.

“…Data show increasing chlorophyll a since 2013, and highly variable PAR that is higher in the last 5 years than the first 5 years of record. The long‐term trend has been associated with changing ice cover phenology and warming spring temperatures (Christianson et al, 2021 ; Preston et al, 2016 ). High interannual variability and an underlying long‐term trend prevent the detection of a COVID‐related effect on the 2020 season.…”

The period of disrupted human activity caused by the COVID-19 pandemic, coined the "anthropause," altered the nature of interactions between humans and ecosystems. It is uncertain how the anthropause has changed ecosystem states, functions, and feedback to human systems through shifts in ecosystem services. Here, we used an existing disturbance framework to propose new investigation pathways for coordinated studies of distributed, long-term socialecological research to capture effects of the anthropause. Although it is still too early to comprehensively evaluate effects due to pandemic-related delays in data availability and ecological response lags, we detail three case studies
