So, is anyone interested in and wants to follow people doing marine biogeochemistry? I might have a starter pack for you! (also, I blame @malinodalen.bsky.social for this) bsky.app/starter-pack... Spot anyone not there (maybe you?), say something.

Does anyone know what the best temperature, salinity, pH (maybe O2) logger is for in situ application at 10m depth in seawater? Obviously a SeapHox is great but looking for something more affordable. 🌊

I am hiring! Want to join a collaborative project with hydrologists, ecologists, biogeochemists, and microbiologists? Come join us here in Boston. Looking for a tech and postdoc - links here for tech position: tinyurl.com/mpm82399 and here for postdoc: tinyurl.com/4vrra3mf please share widely! 🧪🦠

👋 at #AGU23 & interested in a PhD on climate impacts on freshwater nutrient cycling (& in moving to Aotearoa New Zealand)? Please come have a chat! Position details here: sites.google.com/view/wells-s... Where to find me: I’ll be here all week, so pls feel free to send an email/ msg.
