Session Proposal: Advances in Arctic Carbon Cycling: Perspectives from Multiple Proxies, Timescales, and Methods (AGU25)

C001
Advances in Arctic Carbon Cycling: Perspectives from Multiple Proxies, Timescales, and Methods

Session ID#: 251810

Session Description:
The Arctic region stores a globally significant amount of carbon, which is vulnerable to release as the Arctic continues to warm and permafrost thaws. A lack of baseline data on many Arctic systems makes it challenging to interpret change and predict the fate of the Arctic carbon reservoir. As a result, it is increasingly important to understand the nuances of the Arctic carbon cycle, including but not limited to the terrestrial to aquatic transfer of carbon, carbon burial in the Arctic Ocean, and biogeochemical transformations that drive carbon dioxide and methane release. This session aims to bring together scientists studying any aspect of the Arctic carbon cycle. We welcome research on different Arctic systems (e.g., lake, river, ocean, soil), and studies that encompass a variety of proxies, methods, and timescales (modern or paleo).
