ASLO Aquatic Sciences 2021 Limnological Processes Beneath Ice Cover Session
From Tuesday 22 June 2021
To Sunday 27 June 2021
Location Online

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 presentations on aquatic physical, chemical, and biological processes beneath ice covers (details below). Please consider submitting an abstract to our session before the 12 March 2021 deadline, and share widely with colleagues who might be interested.

We look forward to seeing your abstracts!

Session SS49: Limnological Processes Beneath Ice Cover
Ice cover is fundamental to the seasonal cycles of inland waters and is a permanent feature of many high-latitude aquatic environments. The presence of ice limits light penetration, influences water column mixing and diminishes atmospheric ventilation. These influences produce a cascade of effects on water column and sediment physiological and biogeochemical processes.  For example, long term datasets collected from ice covered lakes in the polar regions have revealed unique physiological adaptations to permanent ice cover, and investigations of temperate systems during the ice covered season have highlighted the importance of under ice processes in the regeneration of nutrients. Experimental data show that autotrophic and heterotrophic organisms respond at the individual and community level to the formation of ice-cover. Rising global temperatures are decreasing ice cover duration and altering ice thickness, which clearly have implications for freshwater biogeochemistry. This session aims to further our understanding of limnological processes under lake ice and highlight the consequences of changing ice covers for limnological processes across local, regional and global scales. We welcome submissions focused on any aspect of limnology including physical, biological, and chemical processes under ice cover and during open water – ice cover transitions, especially those that aim to link biogeophysical processes.
