- Abstract
- The quality of lake ice is of uppermost importance for ice safety and under-ice
ecology, but its temporal and spatial variability is largely unknown. Here we
conducted a coordinated lake ice quality sampling campaign across the
Northern Hemisphere during one of the warmest winters since 1880 and show
that lake ice during 2020/2021 commonly consisted of unstable white ice, at
times contributing up to 100% to the total ice thickness. We observed that
white ice increased over the winter season, becoming thickest and constituting
the largest proportion of the ice layer towards the end of the ice cover season
when fatal winter drownings occur most often and light limits the growth and
reproduction of primary... (More) - The quality of lake ice is of uppermost importance for ice safety and under-ice

reproduction of primary producers. We attribute the dominance of white ice
before ice-off to air temperatures varying around the freezing point, a condition
which occurs more frequently during warmer winters. Thus, under continued global warming, the prevalence of white ice is likely to substantially increase during the critical period before ice-off, for which we adjusted commonly used equations for human ice safety and light transmittance through ice.
