Fig. 2

Nitrogen fixation rates (nmol N L−1 d−1) measured by 15N2 incubation (blue bars) from January to March and by FARACAS (blue line) from Jan. 27th to 28th in 2019. The error bars show standard deviation of the triplicate incubations (except for duplicates on Feb. 11th). Rates above the MQR, LODMontoya, or LODsd are depicted with green marks.
