Let's give a try to the new #QuotePost functionality, so that I can remind the names of the lead authors of my new co-authored #review paper published in the @EuroGeosciences #journal #Biogeosciences, as well as which team and research center I represent in this #synthesis!

Warming Arctic lakes may release more methane than expected

The findings are important because #methane is over 25 times more powerful than #CarbonDioxide as a #GreenhouseGas. #Arctic lakes are already major natural methane sources globally, but the processes that control how methane is produced and released from lake sediments have remained poorly understood—until now.

"We were surprised by how clearly the productivity of the ecosystem was linked to methane production," said Marie. "Our results show that warmer and wetter conditions increase biological productivity in Arctic lakes, which in turn drives methane #emissions from their sediments."

Most methane was produced within the top 10 cm of lake #sediment. In these shallow layers, the combination of fresh, organic-rich material and enhanced microbial activity creates ideal conditions for methane generation. The researchers calculated how much methane is likely to diffuse from the sediment into the overlying water and eventually into the atmosphere.

"The Arctic is changing rapidly, and we need to understand all the feedback involved," said Marie. "Our work suggests that increases in ecosystem productivity—something we could think of being positive—can also increase methane release and further accelerate warming."

Gilad Antler is a really cool researcher doing #biogeoscience out of a #science station on the #RedSea, and he's looking for MSc and PhD students to join his #lab. ( #AcademicJobs )
So, he made this neat video to tell you more about it:

I´m happy that our investigation about #nitrousoxide #N2O in the Elbe Estuary is out now as a preprint in #biogeoscience
Especially the Hamburg Port produce and emit a huge amount of #N2O to the atmospere.
Spoiler: A CO2 equivalent of a middle town per year!

Tomorrow morning! Grab a coffee, put on your #AGU22 lanyard, and head over to start your Fall Meeting with some #CriticalZone research presented by members of the #BigDataCluster.

"Distinct Regulation of Riverine Inorganic Carbon by Soil CO2 and Climate" is included in 90 minutes of exploring the Frontiers of #WaterQuality.

Climate Controls on River Chemistry

"Results indicate that in places where river discharge dwindles in a warming climate, solute concentrations will elevate even without human perturbation, threatening water quality and aquatic ecosystems."
