New paper in Ecosystems led by @biogeobob.bsky.social! Fun NSF-funded collaboration tracing the immediate & delayed whole-stream respiration of dissolved organic carbon using 13C-glucose & 13C-fescue leachate additions + 13C-DIC analyses w/ Michelle Baker & Stephen Plont. 💧🌎

New R script for calculating dissolved GHG concentrations & air-water fluxes (CO2, CH4, N4O) directly from headspace data in inland waters (from ppmv to mmol/m2/d). Built on the great work of R. Marcé(Rheadspace.R) and K.S. Aho (headspace_calcs). github.com/songchunlin/...

New research has shown rivers release ancient carbon dioxide into the atmosphere, uncovering a greater role for plants and soil in the carbon cycle 🌱 Featuring @profbobhilton.bsky.social‬ Read the full story: buff.ly/yv82d3X

Final week for submission! Join us at AOGS 2025 in Singapore (July 27–Aug 1)! We’re hosting a session on “Aquatic Biogeochemical Cycles in Asia Under Climatic and Human Disturbances.” Submit your work by Feb 18, 2025. #AOGS2025 #Biogeochemistry www.asiaoceania.org/aogs2025/pub...

Great review paper on the carbon cycle from the entire Arctic! The authors show that carbon emissions from Arctic inland waters (262 Tg C) offset the terrestrial carbon sink (–195 Tg C), a finding consistent with the conclusion of our paper (10.1126/sciadv.adp0024). www.nature.com/articles/s43...
