Dear colleagues,
We would like to draw your attention to the following session at the AGU 2020 Fall Meeting being held on 7 – 11 December 2020. This year's meeting will be mainly virtual and will have reduced registration rates.
Biogeochemical dynamics in glacial ecosystems driven by climate change (B014)
https://agu.confex.com/agu/fm20/prelim.cgi/Session/101735
Glaciers and ice sheets, the Earth's largest freshwater reservoirs, are drastically changing in response to climatic warming. Rising temperatures and anthropogenic influences on glaciers in polar and mountain regions enhance microbial growth leading to intensified biogeochemical cycling of carbon and nitrogen. Surface and subglacial biogeochemical processes affect downstream ecosystems: for example, microbial growth and particulates lead to reduced albedo on glacial surfaces, increased meltwater generation and changes to organic matter flux, potentially enhancing subglacial greenhouse gas production. Recent advances in molecular techniques and high-resolution chemical analysis significantly improve our understanding of biogeochemical cycling, helping to integrate data into global models. In this session, we invite observational, experimental, and modelling contributions that lead to a better understanding of biogeochemical cycles driven by microbial communities in glacial ecosystems. We encourage submissions that provide insight into carbon and macro/micro-nutrient exchange, microbial activity, and microbial community connections in supraglacial, subglacial and downstream ecosystems through space and time.
Conveners: Matthias Winkel (GFZ-Potsdam), Trinity Hamilton (University of Minnesota), Jon Hawkings (Florida State University/GFZ-Potsdam) and Trista Vick-Majors (Michigan Tech)
We would be delighted if you consider submitting an abstract. The deadline for submissions is July 29th (11.59 PM EDT). Please forward this message to any colleagues who you think might be interested.
Best wishes,
Matthias, Trinity, Jon and Tristy
