Ad for 2 graduate student positions and and 1 lab and field assistant position at UCSB. More info go to audreythellman.weebly.com

Hello freshwater friends! I’m starting a lab(!!) and recruiting 2 students to start Fall 2026 and a lab/field assistant to start this Fall 2025! Research topic is broad: rivers 🛶, ice/snow ❄️, nutrients 🍂, algae 🌱see below for more info

Please pass this along to any interested folks :)

A graph of atmospheric carbon dioxide concentrations at the Mauna Loa observatory, Hawaii, from 1958 to 4th February 2025. It shows carbon dioxide levels rising at an accelerating rate over the decades. This is known to be due to emissions of carbon dioxide from human activity, mainly fossil fuel burning but also deforestation. The first CO2 concentration value in March 1958 was 315 parts per million (ppm). The latest daily value is 426 ppm. The graph also shows a seasonal cycle of a few ppm within each year, which is known to be linked to the growing season in the northern hemisphere causing a temporary uptake of carbon in spring and summer and release in autumn. The graph is produced routinely by the Scripps Institution of Oceanography, UC San Diego.

Although NOAA's page on atmospheric CO2 levels has vanished, you can still get this vital information from Ralph Keeling's team at the Scripps Institution of Oceanography, UC San Diego keelingcurve.ucsd.edu

Don't let science be hidden

I’m thrilled my @hubbardbrook.bsky.social dissertation work is finally out! If you want to read about how moss may provide room/board for algae in nutrient poor streams, check it out 🌿

Session conveners at AGU

We’re super excited for a ✨cool✨ session on freshwater ice at #AGU24!!

If you’re here we’ve got talks Wed morning in 152B at 8:30 am ft. invited speakers Kathi Jo Jankowski & @hildug.bsky.social , posters in the afternoon, AND an ice breaker social at 5pm after the posters! (GC31H, GC33M) 🧊
