Oceanographer and lead of MBARI's Carbon Flux Ecology team. I think a lot about sinking particles, the carbon cycle, and microscopic creatures. Otherwise: fiber art, designing/making clothes, chickens. Views expressed here are my own.
Working with engineers and other scientists to make this dream a reality is a privilege that I don't take for granted. I can't wait to analyze this data and share soon. You can learn more about this ongoing work here: www.mbari.org/news/new-mba...

When I was in grad school I spent a lot of time thinking about individually sinking phytoplankton cells, and wondering if it actually mattered in the real ocean. It is nice to finally answer that question!

Key takeaways:
1) Most phytoplankton were exported in sinking particles.
2) Almost all of these exported taxa were packed in large particles.
3) Diatoms and Hacrobia were enriched is the key particle types.
4) POC flux magnitude is correlated with relative composition of these two taxa in particles.

I have been fantasizing about making a zine for a while now….i am sick of digital communication and algorithms.
