Abstract:
The dust used in the TOC experiment underwent only step 1. The unlabeled dust in the labeled experiment underwent steps 1 and 2, where the labeled dust underwent steps 1, 2 and 3. The unlabeled and labeled dust were analyzed for total organic carbon and δ¹³C-total organic carbon.

Dust preparation:
1) Dry heat sterilization (160°C for 2 h)
2) Washing with autoclaved artificial seawater and ultrapure water
3) Loading with ¹³C-labeled Spirulina:
→ dust was added to a solution of artificial seawater and 5% ¹³C-labeled Spirulina (conc. Ca. 95 µM) for 168 h
