Corrigendum: N2 fixation in the Eastern Arabian Sea: Probable Role of Heterotrophic Diazotrophs

In the original article, we made a mistake in the reporting N2 fixation and carbon uptake rates. While reporting mean N2 fixation and mean carbon uptake rates, we forgot to include the duplicate values in calculation in the original article. We provide correct values in the following sections, figures and tables as described. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way.
RESULTS AND DISCUSSION
In the sub-section “N2 Fixation Rate and Carbon Uptake”, first line of the first paragraph:
N2 fixation rates varied from 4.01 - 238.07 nM N hr-1, while carbon uptake rate ranged between 16 - 1628 nM C hr-1 (Fig. 5).
In sixteenth line of the first paragraph:
Heterotrophs contributed up to 52% to the total N2 fixation (estimated from light and dark incubations, assuming light incubations correspond to phototrophic and dark to heterotrophic).
In the eighth line:
Based on the higher N2 fixation values at the surface for dark incubation, we hypothesize that heterotrophic fixers dominantly (about 52% of total N2 fixation is by heterotrophs) play an important role in fixing N2.
In the original article, there were mistakes in Fig. 5, Fig. 6, Table 1 and Table 2 as published. The figures and tables are now redrawn and reported with the revised N2 fixation and carbon uptake rates. In Table 2, we reported areal rates wrongly in the last row. The corrected Fig. 5, Fig. 6, Table 1 and Table 2 are presented below. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way.
Conflict of Interest Statement
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
