We would like to call your
attention to a session at the ASLO Aquatic Sciences 2021
Virtual Meeting (22-27 June 2021) that will bring together pre
sentations on aquatic physical, chemical, and biological processes beneath
ice covers (details below). Please consider submitting an abstract to our session before the 12 Marc
h 2021 deadline, and share widely with colleagues who might be int
erested.
We look forward to seeing your abstracts!

Sessi
on SS49: Limnological Processes Beneath Ice Cover
Ice cover i
s fundamental to the seasonal cycles of inland waters and is a permanent fe
ature of many high-latitude aquatic environments. The presence of ice limit
s light penetration, influences water column mixing and diminishes atmosphe
ric ventilation. These influences produce a cascade of effects on water col
umn and sediment physiological and biogeochemical processes. For exam
ple, long term datasets collected from ice covered lakes in the polar regio
ns have revealed unique physiological adaptations to permanent ice cover, a
nd investigations of temperate systems during the ice covered season have h
ighlighted the importance of under ice processes in the regeneration of nut
rients. Experimental data show that autotrophic and heterotrophic organisms
respond at the individual and community level to the formation of ice-cove
r. Rising global temperatures are decreasing ice cover duration and alterin
g ice thickness, which clearly have implications for freshwater biogeochemi
stry. This session aims to further our understanding of limnological proces
ses under lake ice and highlight the consequences of changing ice covers fo
r limnological processes across local, regional and global scales. We welco
me submissions focused on any aspect of limnology including physical, biolo
gical, and chemical processes under ice cover and during open water – ice c
over transitions, especially those that aim to link biogeophysical processe
s.
