The American Geophysical Union (AGU) is accepting abstracts for the 2023 AGU Fall Meeting. This hybrid meeting will take place 11-15 December 2023 in San Francisco, California and online.
The following sessions are accepting abstracts:
SESSION C014 - Coupled-system Processes of the Central Arctic Atmosphere-Sea Ice-Ocean System: Harnessing Field Observations and Advancing Models
Conveners: Matthew Shupe, Amy Solomon, David Clemens-Sewall, and Emelia Chamberlain
The central Arctic coupled environmental system is changing rapidly, with dramatic implications for climate, weather, ecosystems, and society. Importantly, many of these changes and processes are interdependent. For example, thinner and less extensive sea ice can impact the flow of heat, the exchange of gases, seasonal melt and freeze of ice, ice dynamics, light available for biological productivity, and many other related physical, biogeochemical, and ecological processes. In this session, conveners welcome field, laboratory, remote sensing, and modeling studies that examine all aspects of the changing central Arctic coupled system, especially including processes that cut across the atmosphere, sea ice, snow, ocean, biogeochemistry, and ecosystem. Submissions are encouraged that incorporate cross-disciplinary research topics, examine interseasonal linkages, conduct observation-model synthesis, and/or bridge the spatial and temporal scales between in situ observations and large scale remote-sensing and modeling. Contributions from recent central Arctic field campaigns like MOSAiC are particularly relevant.

SESSION B024 - Consequences of Changing Seasonality for Phenology and Biogeochemical Cycling in a Warming Arctic
Conveners: Amanda Young, Haley Dunleavy, and Marion Syndonia Bret-Harte
As Arctic ecosystems undergo rapid change through warming and an intensified precipitation regime, these changes are not uniform throughout the year but have varying seasonal impacts. Changing seasonality is likely to alter not only important ecosystem functions, but also the timing of linked biotic and abiotic processes in the Arctic’s tundra, streams, and lakes. This could potentially lead to mismatches between organisms and their environments, with implications for carbon and nutrient cycling, permafrost stability, and culturally significant food webs. Conveners invite presentations that use observational and experimental studies to identify seasonal responses of organisms and ecosystems to climate change across different spatial and temporal scales in terrestrial and aquatic Arctic ecosystems. This session will provide a forum to link the consequences of changing seasons through remote sensing, long-term monitoring, and studies on phenology, and population, community, and ecosystem ecology to address ecological dynamics in high-latitude ecosystems, and to promote collaboration.
Invited presenters include stream hydrologist Arial Shogren (University of Alabama) and climate change ecologist Eric Post (University of California Davis) in the conversation about changes in Arctic seasonality.
