The American Geophysical Union (AGU) is currently accepting abstract submissions for the 2019 Fall Meeting. The meeting will be held 9-13 December 2019 in San Francisco, California.

Conveners of the following three sessions invite abstract submissions:

SESSION B028: Causes and Consequences of Changing Disturbance Regimes in Boreal Forests across the Globe
Conveners: Heather Dawn Alexander, Jennie DeMarco, Alison Paulson, and Rebecca E. Hewitt

Arctic and sub-arctic boreal forests are warming at an accelerated rate compared to the rest of the globe. Coincident with this warming have been changes in disturbance regimes, including increased wildfire activity, insect and pathogen outbreaks, and permafrost thermokarsting, which can disrupt forest ecosystem structure, composition, and function, and affect forest recovery. Boreal forest resiliency post-disturbance could have large consequences for global climate because of complex biogeophysical feedbacks that impact carbon sequestration, hydrological cycling, and surface energy fluxes. To better understand the interacting processes that determine boreal forest resiliency and vulnerability following disturbance and feedbacks to the climate system, conveners invite contributions from scientists whose research focuses on the causes and consequences of changing disturbance regimes in boreal forests across the globe. Presentations can address any spatial or temporal scale, from microbial to remotely sensed landscape-level processes affected by the relationships between climate, disturbance, and vegetation in the boreal forest.

SESSION B017: Arctic Land Surface Energy Fluxes and their Impact on the Earth System under Current and Future Conditions
Conveners: Jacqueline Oehri, Gabriela Schaepman-Strub, Michael M. Loranty, and Sara M. Morris

Climate over Arctic land warmed considerably by up to 5°C in the last century and a substantial increase in temperature and precipitation is projected for the 21st century. These changes indicate alterations in Arctic land surface energy fluxes. However, despite their importance, the Arctic land surface energy budget and its components have received relatively little attention in the past. This session aims to improve the current understanding of the Arctic surface energy budget and its relevance for the Earth System. Conveners invite researchers to present theoretical, observational, empirical, and modeling studies on Arctic surface energy fluxes and the energy budget and interactions with processes such as carbon and water cycling, permafrost thaw, and biodiversity change. Conveners invite researches of all relevant disciplines (e.g., remote-sensing, climatology, ecology) and scales (local, pan-arctic, global) to present their findings, data, and/or methods.

SESSION C007: Arctic Coastal Change: Circumpolar Truths and Future Outcomes
Conveners: Anna M. Irrgang, Louise Melanie Farquharson, Ming Xiao, and Craig T. Connolly

Arctic coastlines are highly vulnerable to anthropogenic and climate-driven changes. The goal of this session is to create a platform for discussing and presenting recent research on the changes in Arctic coastal dynamics from a broad interdisciplinary perspective. Conveners invite a breadth of studies that cover topics related to Arctic coastal changes, including the driving forces, geomorphological processes, and potential impacts on ecosystem ecology, biogeochemistry, infrastructure, and social systems. Specifically, conveners welcome abstracts on cross-disciplinary studies at the nexus of 1) environmental variables that influence nearshore hydrological, geomorphological, ecological, and biogeochemical processes; 2) spatial and temporal variability in coastal change and key driving forces; and 3) the impacts of Arctic coastal change on nearshore ecosystem function, coastal communities, infrastructure, and hazards. Conveners also welcome studies which utilize paleoenvironments as an analogue for current and future change, as well as studies that explore new technologies and methods.
