Really fantastic @goldschmidt-confer.bsky.social #Goldschmidt2025 conference in Prague! Thanks @eageo.bsky.social
Some 🧪🥼⚒️ highlights #greenhouse gases in rivers & lakes; timescales of #water and element #storage in catchments; #enhancedweathering state of play; closing the geological #C budget.

Great to work with Jamie and the team on this, with fantastic 1000 year records gained from (lots of) lake coring, sedimentology and geochemistry over 5 years on @ukri.org and @leverhulme.ac.uk funded work 🧪 ⚒️ @oxuniearthsci.bsky.social

This study takes use beyond timescales we can study using modern day rivers.
1000 year lake sediment records allow us to untangle the role of extreme earthquake triggered landslide events, versus storm driven processes.
Tectonics & climate combine to moderate #carbon transfers + long term burial

Why does old river #CO2 matter?
#Soils can store carbon for thousands of years.
But this old carbon, as well as ancient carbon from rocks, is leaking sideways into rivers and making its way back to the atmosphere.
Suggests plants are working harder to take up carbon from the atmosphere

Our international research team studied more than 700 river reaches from 26 different countries across the world.
Compiling published data and making new #radiocarbon measurements from previously poorly studied rivers in the Arctic, South East Asia and China.
It was a great team to work with!
