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 A022 - Atmospheric Composition and Chemistry in the New Arctic
Conveners: Rebecca J. Sheesley, Claudia I. Czimczik, and Kelley Barsanti

Climate is changing rapidly in the Arctic. This session will provide a platform for discussion of long-term monitoring, field campaigns, remote sensing studies, and modeling efforts to describe, understand, and predict the changing land-atmosphere interactions and associated impacts on atmospheric composition and chemistry of the Arctic region.

Long-term monitoring of key parameters including plant distribution, permafrost, sea ice cover and atmospheric composition can be used to identify trends. Intensive campaigns can provide detailed characterization to improve understanding of complex emissions and processes while also providing validation and intercomparison points for modeling efforts. Biogenic emissions including volatile organic compounds and bioaerosols can have a large impact on atmospheric composition and cloud-aerosol interactions. Understanding the impacts and distribution of wildfire emissions continues to be of crucial in the Arctic and near-Arctic.

By bringing together research from various disciplines this session provides an opportunity to better understand ongoing transformation of the Arctic.

SESSION C011 - Arctic Coastal Dynamics: Rates, Impacts, Hazards and Implications for the Future
Conveners: Louise Melanie Farquharson, Anna M. Irrgang, Melissa Ward Jones, and Benjamin M Jones

Arctic coastlines are highly vulnerable to anthropogenic and climate-driven changes. Coastal hazards like erosion and flooding are intensifying and creating risks for coastal communities. The goal of this session is to create a platform for discussing recent research on the changes in Arctic coastal dynamics, resulting hazards and risks, and advances in modeling. Conveners invite studies that cover topics related to Arctic coastal changes, the driving forces, geomorphological processes, modeling approaches and impacts on ecosystem ecology,biogeochemistry, infrastructure, and social systems. Further, conveners discuss the co-production of knowledge and tools for forecasting coastal hazards and risks to quantify their social and economic impacts. Conveners welcome abstracts on cross-disciplinary studies at the nexus of 1) environmental variables that influence nearshore hydrological, geomorphological, ecological, and biogeochemical processes; 2) variability in coastal change and key driving forces; 3) collaborative approaches from communities, researchers and agencies to develop monitoring programs to support hazard forecasting.

SESSION HE002 - Arctic Ocean Changes and Processes
Conveners: Benjamin Rabe, Ying-Chih Fang, Alexandra Jahn, and Laura Whitmore

This session aims to foster discussion between pan-arctic, regional, observational, modeling, and societal activities in Arctic Ocean research. Changes in Arctic Ocean surface temperature, sea ice, and ocean circulation are ongoing and may have regional or global forcing,responses, and economic implications. Phenomena such as Atlantification and Pacification highlight the importance of both regional processes as well as the connection to the rest of the world’s oceans. Efforts in the form of large-scale hydrographic surveys and process studies – as well as satellite interpretation, earth system, and regional ocean modeling – have contributed to our understanding of climate responses and drivers and the Arctic Ocean’s role in the global climate system. Observations now cover several decades of physical, chemical and biological variables, thanks to various observational programs that provide the context for multidecadal changes. Coordinated modeling efforts and process studies are also crucial to understand these changes. Conveners invite contributions from studies investigating small-, mesoscale, regional, or pan-Arctic domains or the subarctic-arctic connection. Interdisciplinary studies of the atmosphere-sea ice-ocean system, chemical processes, and the ecosystem are invited. Conveners also welcome contributions related to Arctic Ocean research paradigms, outreach activities and links to societal issues.
