New papers continue to emerge from our 2019 AGU Chapman Conference on Winter Limnology, many published in the special issue of JGR Biogeosciences that was developed at the conference. A recent one develops the Lake Ice Continuum Concept as a conceptual model for understanding how key aspects of the physical, chemical, and ecological structure and function of lakes vary along a continuum of winter climate conditions mediated by ice and snow cover. It is co-led by first authors who contributed equally – Emily Cavaliere, Isabelle Fournier, Vendy Hazuková, Garrett Rue and Steve Sadro.
