St Andrews Earth & Environmental Sciences

@earthscista.bsky.social

The School of Earth and Environmental Sciences at the University of St Andrews is a vibrant scientific community that studies the Earth and its neighbours in space. https://www.st-andrews.ac.uk/earth-sciences/

New findings from Rika, Eva, Tony and I: We used evolutionary biology techniques to investigate how nitrogen sustained early life on Earth, and found that ammonium was key! It could have been supplied by hydrothermal activity and other planetary processes. www.science.org/doi/10.1126/...

Abiotic sources of fixed nitrogen sustained early ecosystems for several hundred million years after the origin of life

Genomic evidence suggests early life relied on ammonium and other N molecules before biological nitrogen fixation evolved.

This afternoon, I asked faculty, staff, and research students in the School of Earth & Environmental Sciences @earthscista.bsky.social for their predictions/guesses for the highest temperature that will be recorded in the UK this week. With 34 responses, our ensemble mean is 39.2°C.

That’s a wrap on our inaugural 2nd-year @earthscista.bsky.social undergraduate field trip to the Lake District! We were blessed with predominantly glorious weather ☀️ which made measuring water quality & transport, carbon flux and boundary layer properties all the more fun 😁

Final prep underway for our inaugural 2nd-year undergrad Environmental Earth Science field trip to the Lake District next week! @earthscista.bsky.social We'll be exploring boundary layer meteorology, soil erosion, nutrient transport, water quality & carbon flux. Hoping the weather is on our side...
