Sulfate-reducing bacteria break down a large proportion…
Phys.orgSometimes it meant climbing mountains.
Sometimes it meant climbing buildings.
Cluster member Jeff Munroe visited 20 sites last fall as part of the 2024 Collectors Tour.
Samples from the collectors become the data used as part of our source-to-sink study of how #dust moves through the #CriticalZone

We are, quite literally, made of the landscapes we inhabit – the #air we breathe, the #water we drink, the #food we eat.
In this article, contributor Nolan Monaghan explores how biophysical processes like the carbon and nitrogen cycles bridge the local and the global, laying the groundwork for a deeper, metaphysical connection with the planet.

After the last presentation at #BOGS2024 we had presentations for
Best poster to Gemma Baker (The potential of lipid biomarkers to interpret the dietary profiles of 2 lemur species with different feeding habits)
Archie Douglas award for the best oral to Joe Hingley (Evaluating grain size controls on lipid biomarker distributions in marine sediments)
Congratulations to both!
