Abstract:

Suspended particulate matter and elemental stoichiometry data from the mesocosms experiment conducted in the Canary Islands in autumn 2019. Depth-integrated (0-2.5m) water samples were taken in 2-days intervals over the course of 33 days. There was no evidence for significant amounts of particulate inorganic carbon, and therefore, POC and TPC measurements were averaged and interpreted as POC. This “POC TPC average” should be used for further analysis. The upwelling treatment started on day 6. Methodological details in Goldenberg et al. (doi: 10.3389/fmars.2022.1015188).
