A preprint of my article, “Subterranean karst environments as a global sink for atmospheric methane” is now online. My team and I present research on 36 caves from across the world and show that the methane concentration of cave air is depleted compared to the atmosphere. Our work demonstrates that atmospheric methane is consumed by methanotrophic bacteria living in caves. Additionally, our work shows that the methanogenic processes of carbonate reduction and acetate fermentation are widespread in the environment. The article can be found here https://www.preprints.org/manuscript/201708.0009/v1

The confirmed speakers for the Advances in origin of life research session at AGU are Dr. H. James Cleaves and Joshua Goldford. We are excited to have abstracts rolling in and we look forward to your abstract submission by August 2nd. The session page is located here. See you in New Orleans!

Our sampling from Rondônia, Brazil is showing that pastures are emitting methane whereas primary forests and secondary forests are neutral and weakly consuming respectively. What is behind the production in the pastures?

I am the primary convener for the session Advances in origin of life research at the 2017 American Geophysical Union conference in New Orleans. Abstract submission is now open and you can submit an abstract for the session here. I look forward to seeing you in New Orleans!

Is this the map to find Luke Skywalker or the current design for our environmental methane sampling system? We will install this system later this year in Brazil’s Tapajos National Forest. Special thanks to Rick Wehr for the catchy name!
